Touch the money — even for a moment — and the exchange is dead. The Qualified Intermediary exists for one purpose: to stand between you, the Exchangor, and every dollar that flows through your 1031 transaction.

You Cannot Control the Proceeds

The rule is absolute. If you receive or control the proceeds from the sale of your Relinquished Property you are disqualified from the Section 1031 Exchange. No partial credit, no grace period. The entire tax deferral collapses.

This is why the QI's core function is to handle the money so that the Exchangor never touches it. The QI stands between you and the money.

The QI Is Not Your Agent

This point deserves its own section because it is routinely misunderstood. The Qualified Intermediary is an independent third party. THE QUALIFIED INTERMEDIARY IS NOT YOUR AGENT AND YOU SHOULD NOT TAKE LEGAL OR ANY OTHER ADVICE FROM HIM. The QI is paid by the Exchangor to ensure that everything regarding the Net Sales Proceeds is done in accordance with the rules of Section 1031 — and then to provide written proof of how it was done. That is the scope of the engagement. If you have legal questions about your exchange, get a lawyer. The QI is not that person.

What the QI Actually Does

The QI holds the money. When the Exchangor the Relinquished Property, the Net Sales Proceeds are transferred to the QI, not to the Exchangor. When the Exchangor is ready to close on the Replacement Property, the QI releases those funds directly to the Closer to complete the purchase.

The Risk You Cannot Ignore

The Qualified Intermediary could end up losing or stealing all of your money. This is not a theoretical concern. The industry has seen QI failures that left Exchangors with wiped-out proceeds and a completed tax event they could no longer defer. The instruction is direct — do not allow the QI to take possession of your funds in a way that leaves you without recourse. Choosing and monitoring your QI is not a formality; it is one of the highest-stakes decisions in the entire exchange.

Who Can Be the Exchangor

The Exchangor doesn't have to be an individual. An LLC, a partnership, a corporation, or any business entity can be the Exchangor — provided the Replacement Property is taken in the same name that held the Relinquished Property. There is a narrow exception for a single-member LLC treated as a disregarded entity, but the underlying principle holds: the entity that sells is the entity that buys, and the QI holds the funds in between.

Sell a duplex for $400,000 that you paid $200,000 for and you might expect to owe tax on $200,000 of profit. But after a decade of depreciation deductions, the IRS sees a gain of $265,400 — and it taxes two different slices of it at two different rates, producing a federal bill of $56,350 before a single state adds its share.

How the Basis Falls to $134,600

Assume that the Taxpayer bought his duplex for $200,000 cash, allocating $180,000 to the building and $20,000 to the land. Land can't be depreciated — the theory is that land isn't "used up" in the process of producing income the way a building is. So only the $180,000 building value goes onto the depreciation schedule.

Residential rental property is depreciated over 27.5 years using straight-line depreciation, meaning the same amount comes off each year: $6,540 annually, or $545 a month. Over ten years, the Taxpayer has claimed $65,400 in depreciation deductions.

That depreciation doesn't just reduce his taxable income year by year — it also reduces his basis in the property. Basis is what the Taxpayer paid, plus any capital improvements, minus depreciation taken. With no improvements and $65,400 in depreciation claimed, his depreciated basis is $134,600 (that's $200,000 minus $65,400).

Why the Gain Is $265,400, Not $200,000

When the Taxpayer sells for $400,000, the IRS computes his capital gain as the difference between his sales price and his depreciated basis — not what he originally paid.

$400,000 minus $134,600 equals $265,400.

That number is $65,400 larger than his true economic profit, and it's no coincidence: the figure exactly matches the depreciation he claimed. Every dollar of depreciation deduction he took over ten years lowered his basis by a dollar and, by that same amount, increased the gain the IRS will tax when he sells.

Two Gains, Two Tax Rates

The $265,400 gain is really two separate amounts that the tax code treats differently.

The first is true capital gain: the difference between what the Taxpayer paid ($200,000) and what he sold for ($400,000), which is $200,000. This is taxed at the long-term capital gains rate — 20% in his bracket — producing a tax of $40,000.

The second is depreciation recapture: the $65,400 that depreciation deductions carved out of his basis. The IRS requires him to "recapture" those deductions at sale. Because his straight-line depreciation was the same amount each year, the recapture rate is capped at 25%, yielding a tax of $16,350.

Add them together: $40,000 plus $16,350 equals $56,350 in federal tax on a sale where the Taxpayer's out-of-pocket cost was $200,000 and his true profit was the same.

What Changes — and What Doesn't

The source of the purchase money doesn't affect any of this. If the Taxpayer had borrowed $150,000 of the purchase price instead of paying all cash, his gain and his tax liability would be identical — he still paid $200,000 for the property and sold it for $400,000. Paying off the loan at closing doesn't change the sales price the IRS sees.

Capital improvements do matter. In a later scenario, the Taxpayer adds garages for $30,000 and claims $7,644 in depreciation on them. Those improvements raise his basis, reduce his gain, and change the split between the regular-gain and recapture buckets — but the two-rate structure stays exactly the same.

The State Tax Line

Every number above is federal only. Most states impose their own income or capital gains tax on top of it, and some municipalities add another layer. The combined federal, state, and local bite will depend entirely on where you live— and that combined number is what a Section 1031 exchange is designed to defer.

Since January 1, 2018, the Tax Cuts and Jobs Act has drawn a hard line inside every real estate transaction: the building exchanges, the contents don't. The furniture, fixtures, appliances, and equipment — what real estate professionals call FF&E — sit on the taxable side of that line, full stop.

What the Law Changed

Before 2018, personal property rode along with the real estate in a Section 1031 exchange without distinction. The beds, the refrigerators, the window units, the washers and dryers — all of it deferred right alongside the building. The Tax Cuts and Jobs Act ended that treatment. Section 1031 now applies to real property only, and the personal property involved in the deal is no longer part of the exchange. Whatever tax is owed on the sale of that FF&E is owed now, not later.

The Mechanics: One Closing, Two Transactions

The split happens at both ends of the exchange. When you sell your relinquished property, the portion of the sales price attributable to the FF&E is treated as a separate sale from the sale of the real estate itself. When you buy your replacement property, the FF&E inside that building is likewise a separate purchase — outside the exchange, outside the deferral.

In practical terms, every deal with furnished units requires an allocation of the sales price and the purchase price between the real estate and the personal property. That allocation isn't optional or cosmetic; it determines what portion of your transaction the exchange actually protects.

Why Almost Every Deal Is Affected

It's tempting to think this only applies to furnished vacation rentals or short-term units. It isn't that narrow. Almost every property you will ever exchange has some furniture, fixtures, or equipment in it — a duplex with appliances, an apartment building with window units and washers and dryers, a commercial space with built-in equipment.

The FF&E on the Buy Side

The replacement property comes with its own FF&E, and that purchase is treated as a separate transaction as well. The exchange proceeds cover the real estate; the personal property inside the building you're buying is handled independently. Getting the allocations right on both the relinquished and replacement sides is essential to understanding what you actually deferred — and what you didn't.

What Can Be Done About the Tax on FF&E

There is room to work here. The tax on the personal property portion isn't necessarily a large bill. If you end up owing taxes on the sale of the personal property in your relinquished property, there are methods to reduce it — potentially to little or nothing. The specifics of how that works are an accounting and tax matter, but the key point is that the liability isn't simply accepted as fixed. Proper allocation and planning on the FF&E side can make a material difference in what you actually owe.

The Core Discipline the TCJA Imposed

The practical discipline the Tax Cuts and Jobs Act imposed is this: you can no longer treat a furnished rental as a single asset for exchange purposes. Every Exchangor — whether an individual, an LLC, a partnership, or a corporation — now carries two sets of books through a transaction. The real estate moves through the exchange. The FF&E moves through a separate accounting. Conflating the two, or ignoring the FF&E side entirely, leaves you exposed to a tax bill you thought you had deferred.

Know what's inside the building before you close. Allocate it. Account for it separately. The exchange protects the real property; everything else is your responsibility to handle on its own terms.

A Section 1031 Exchange defers the 3.8% Net Investment Income Tax right alongside your regular capital gains tax — because gain you never recognize isn't investment income yet, and the surtax has nothing to attach to. The moment you take boot, that calculation changes.

What the Tax Is

The Net Investment Income Tax is an extra federal layer of 3.8%, added by the Affordable Care Act — sometimes called the "Obamacare tax." It applies only above specific income thresholds: single filers with more than $200,000 in annual income, and married couples filing jointly with more than $250,000. If your income sits below those lines, this tax doesn't touch you regardless of what you sell or exchange.

For those above the thresholds, it reaches net investment income — and capital gains from the sale of investment real estate fall squarely within that definition.

How the Exchange Keeps It Deferred

A clean 1031 Exchange produces no recognized gain. You sell the Relinquished Property, the proceeds move to a Qualified Intermediary, and you acquire Replacement Property of equal or greater value. Because the gain is deferred rather than recognized, it isn't investment income yet. There is nothing for the 3.8% to attach to.

This works in exactly the same way that the exchange defers your regular capital gains tax and depreciation recapture — the mechanics are the same. The surtax follows the gain. Defer the gain, and you defer the surtax along with it.

Where Boot Changes the Picture

Boot is where the 3.8% reappears. Boot is anything you receive in the exchange that isn't like-kind real property — cash left over, debt relief, or personal property pulled out of the deal. All of it is taxable up to your gain, and that recognized gain can carry the 3.8% on top of the regular tax.

Say you're a joint filer well above the $250,000 threshold. You sell a duplex, net $100,000 in cash boot, and your recognized gain equals that $100,000. The regular federal capital gains rate applies — and then the 3.8% stacks on top of it. The surtax doesn't replace your ordinary tax; it adds to it.

This is why boot deserves careful attention from higher-earning Exchangors. It isn't just a matter of "a little cash back." Every dollar of recognized boot is a dollar exposed to two separate federal taxes simultaneously.

Depreciation Recapture Carries the Same Risk

The 3.8% doesn't distinguish between capital gain and depreciation recapture when both are recognized. If you take boot and a portion of your recognized gain is attributable to depreciation you claimed on the building — taxed at a maximum of 25% under the Section 1250 recapture rules — the 3.8% layers on top of that as well. On personal property recapture, taxed as ordinary income at up to 37%, the same principle applies to any portion that is recognized rather than deferred.

A full exchange defers all of it: the capital gain, the depreciation recapture, and the 3.8% surtax. Recognized gain, however it is characterized, is the opening the surtax needs.

The Practical Takeaway

If your income is above the thresholds, your actual federal tax cost on any recognized gain will run 3.8% higher than a standard capital gains calculation shows. A clean exchange eliminates that exposure entirely for the duration of the exchange — keep exchanging, and at death your heirs take the property at stepped-up basis, potentially eliminating the deferred gain altogether. Take boot, and you hand the IRS two bites at the same apple.

The 3.8% is a relatively narrow tax — it only reaches higher earners, and only gain you actually recognize. But for those it reaches, structuring the exchange to minimize or eliminate boot isn't just about the regular tax. It's about both taxes at once.

The property you sell and the property you buy do not have to be the same at the time before you do a Section 1031 Exchange. Your Relinquished Property must already be held for investment or business when you sell it, but your Replacement Property only needs to be the type that *can* be held for investment or business by you after you purchase it. What the Seller is doing with it right now has nothing to do with your qualification.

Two Properties, Two Different Standards

When you sell your Relinquished Property — say, the duplex you've owned for ten years — it must already be investment or business property at the moment of sale. That status has to exist before the exchange begins. The safe holding period is a minimum of one year and one day, and the property has to have been genuinely held for investment or business purposes throughout.

The Replacement Property plays by a different rule. The question isn't what the current owner, the Seller, is doing with it today. The question is whether *you*, the Exchangor, can hold it for investment or business purposes after you buy it. That's it. The owner's current use is irrelevant to your qualification.

Why This Matters When You're Scouting Properties

This distinction opens up your candidate pool considerably. A property that the current owner occupies personally, uses in a way that doesn't match your plans, or has sitting idle isn't automatically disqualified just because of how it's being used today. What matters is whether the property is the type — real property — that you can hold for investment or business after closing.

And the Replacement Property has to be real property. The Tax Cuts and Jobs Act of 2018 ended 1031 treatment for personal property: art collections, antiques, airplanes, and similar assets no longer qualify. Even within a real estate transaction, the personal property component — the furniture, fixtures, and equipment the IRS calls FF&E — is carved out and treated as a separate sale. You still need to account for it, but the tax deferral runs only on the real estate itself.

The Seller's Role Is Narrow

The Seller — whoever currently owns your Replacement Property — has almost nothing to do with whether your exchange works. He needs to have appropriate property for you to buy, he must be told that the transaction involves a Section 1031 Like Kind Exchange, and he cannot be a Related Person as defined by the IRS. Beyond that, he simply delivers the property. His intentions, his holding period, his prior use — none of it touches your qualification.

If your Replacement Property is made up of multiple properties, there may be more than one Seller. That's permitted. You can replace a single relinquished property with several replacement properties, which gives you even more flexibility in building a portfolio that fits your investment goals.

One Rule That Does Apply to Replacement Property

There is a title requirement that has nothing to do with intent but everything to do with structure: you must take title to the Replacement Property in the same name in which you held the Relinquished Property. If the duplex was held in your name individually, the fourplex needs to come back in your name individually. There is an exception for a single-member LLC treated as a disregarded entity for tax purposes, but outside that carve-out, the name on the deed has to match.

The Practical Takeaway

The holding-period and intent requirements are front-loaded onto the property you're selling. By the time you're identifying and acquiring Replacement Property, the standard shifts — it becomes a forward-looking question about your intended use, not a backward-looking audit of the current owner's behavior. Scout based on what the property can become in your hands, not what it has been in someone else's.

How long you owned the property before selling it determines which tax rate applies to your profit — and the difference between those rates can dwarf almost every other variable in the transaction.

Two Brackets, One Dividing Line

Within capital gains taxation, everything hinges on a single threshold: one year. Hold a capital asset for one year or less and your profit is short-term capital gains, taxed at exactly the same rate as ordinary income — wages, salary, whatever your regular bracket happens to be. Hold it for more than one year and it qualifies for the long-term rate, a separate, lower schedule.

The top long-term rate is 20%. Short-term gains carry no such cap — they ride up with your ordinary income bracket. For a taxpayer in the top marginal bracket of 37%, that gap is enormous.

What This Looks Like With Real Numbers

The Taxpayer bought a duplex ten years ago for $200,000 and sells it for $400,000. Because he held the property for a decade, every dollar of his gain qualifies for the long-term rate. His depreciated basis is $134,600 — the $200,000 purchase price minus $65,400 in straight-line depreciation claimed over ten years — making his total capital gains $265,400.

That $265,400 splits into two pieces taxed at different rates, but both pieces are long-term. The $200,000 of true economic appreciation (the difference between what he paid and what he received) is taxed at 20%, producing a $40,000 liability. The remaining $65,400 represents depreciation recapture — the IRS clawing back the deductions Adams took each year — and that portion is taxed at a maximum rate of 25%, producing $16,350. Total federal tax: $56,350.

Had the Taxpayer held the duplex for eleven months instead of ten years, that same $200,000 of appreciation would have been taxed at his ordinary income rate — potentially 37% — rather than 20%. On that single piece alone, the short-term bill would be $74,000 versus $40,000. The clock alone created a $34,000 difference.

Depreciation Recapture Runs on Its Own Track

One nuance worth understanding: depreciation recapture doesn't move with the short-term/long-term distinction the same way appreciation does. Straight-line depreciation recapture is capped at 25% regardless — but only when the property qualifies as long-term. A short-term sale would pull recapture into ordinary income rates as well, eliminating even that cap. For Adams, at the 37% ordinary rate, the recapture bill would jump from $16,350 to roughly $24,200. Every layer of gain costs more when the holding period falls short.

Capital Improvements and Basis Don't Change the Logic

When the Taxpayer adds $30,000 in garages and takes an additional $7,644 in depreciation on them, his capital gains drop to $243,044 and his total tax liability falls to $52,261. The math shifts, but the rule doesn't — all of it is still long-term because he held the property more than a year. Capital improvements add to basis, depreciation reduces it, and the net result determines your gain. But which rate applies to that gain remains a function of time alone.

Where the money came from to buy the property, whether the Taxpayer used savings or borrowed $150,000 from a bank, changes nothing about the tax calculation. A mortgage on the property at the time of sale changes nothing either. What he paid, what he claimed in depreciation, and what he sold it for — those are the only variables. And then the clock decides the rate.

Why This Matters for Exchange Planning

A Section 1031 exchange defers the entire tax liability — the long-term capital gains, the depreciation recapture, all of it. But the incentive to defer is sharpest when you've held long enough to qualify for long-term rates. Once you're in that lower bracket, the number worth protecting is real and concrete: in this case, $52,261 in federal tax alone, before state and local taxes are added on top. Keep exchanging, and at death your heirs take the property at stepped-up basis — eliminating the deferred gain entirely.

Keep exchanging under Section 1031, and at death your heirs take the property at its Fair Market Value on the Date of Death — every deferred capital gain and every depreciation recapture balance you carried simply disappears.

What "Basis" Actually Means

When you buy a duplex for $285,000 with $10,000 in acquisition costs, your basis is $295,000. Spend $30,000 on improvements and it rises to $325,000. Then depreciation starts working against you. Separate out the $50,000 land value, and you're depreciating a $275,000 depreciable basis over 27.5 years — $10,000 a year. After five years of rental income and $50,000 in depreciation deductions, your basis has fallen to $275,000. That gap between your basis and what the property is worth is the liability you'd owe if you ever sold without exchanging.

That's the number a 1031 exchange lets you carry forward indefinitely. But "indefinitely" can mean "until death eliminates it entirely."

The Gift Trap Worth Knowing First

Gifted property does not get a step-up. Under IRC Section 1015, if someone gives you property, you inherit their basis — whatever it was when it left their hands. If that basis was low and burdened with decades of depreciation, you now own the problem. Carryover basis means carryover liability. This is why gifting highly appreciated or heavily depreciated real estate is usually the wrong move.

How Section 1014 Erases the Liability

IRC Section 1014 — "Basis of Property Acquired from a Decedent" — resets everything. The basis of inherited property becomes its Fair Market Value on the Date of Death, full stop. A property carried on the books at $275,000 after years of depreciation, and now worth $900,000, passes to an heir with a $900,000 basis. The $625,000 gap never gets taxed. The depreciation recapture that would have been ordinary income on a sale? Gone.

This is the mechanism that converts "tax-deferred" into "tax-free." Section 1031 defers the gain each time you exchange. Section 1014 cancels it at death.

How You Hold Title Changes Everything

The step-up is not automatic for every ownership structure.

For a single individual, the rule is clean: die owning the property outright, leave it to an heir, and the entire basis resets to Fair Market Value.

For married couples, it depends on the state. In a Joint Tenancy state, only the deceased spouse's share receives the step-up — the surviving spouse's own share retains its cost basis. In a Community Property state — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin, and Alaska by opt-in — the surviving spouse gets a step-up on the entire property, not just the inherited half. That double step-up is a significant advantage.

For LLCs and Partnerships, a Section 754 election upon the death of an owner allows the entity to step up the basis of the underlying property in the hands of the beneficiary. The structure preserves eligibility. A C Corporation does not — if the property sits inside a corporation when the shareholder dies, no step-up reaches the real estate. Partnerships and LLCs are the preferred vehicles precisely because they keep this option open.

The Lifetime Plan

Section 1031 keeps you exchanging up — deferring tax, consolidating equity, trading into larger or better-positioned assets across decades. Section 1014 provides the exit. Used together, the strategy is straightforward: exchange throughout your investing life to defer every gain and every recapture obligation, hold the final property in an eligible structure — your own name, a community property arrangement, an LLC or Partnership — and let the step-up at death eliminate what you deferred.

This is one of the three best concepts in the tax code for real estate investors, alongside Sections 121 and 1031. Using all three is the ultimate lifetime investing plan. The math is hard to argue with: decades of deferred gain, canceled entirely.

Buy a home, live in it for two years, rent it out for three — and when you sell just before the five-year window closes, Section 121 shields every dollar of capital gains, including the appreciation that built up while tenants were paying your mortgage. The only tax you'll owe is 25% depreciation recapture on whatever you claimed during the rental period.

How the Five-Year Window Works

Section 121 requires that you owned the property and used it as your primary residence for two out of the five years prior to the sale. That's the key phrase: two out of five. The IRS does not require you to sell when you move out. You can convert the home to a rental for up to three years and still qualify for the full exclusion — up to $250,000 in capital gains for a single filer, $500,000 for a married couple — when you sell before the window expires.

What makes this powerful is what Section 121 covers. The exclusion applies to all capital gains recognized at sale, not just the appreciation from your residency period. The gains that accrued while tenants were living there and the property was climbing in value are sheltered just the same as the gains from year one.

The Numbers on a $350,000 Home

Start with a $350,000 purchase. You live there two years, then rent it for three, claiming depreciation the whole time. Assuming 6.7% annual appreciation, the property sells for $484,050 just before the five-year mark.

At that point you've accumulated $134,050 in true capital gains and $38,182 in depreciation — the latter reducing your cost basis during the rental years. Section 121 eliminates the capital gains tax on the entire $134,050. In a 15% bracket, that's a tax bill that simply disappears.

What remains is the depreciation recapture. The IRS taxes that at your personal tax bracket rate, up to 25%, and 25% of $38,182 is $9,545. That's your total tax on a $134,050 gain — and as the source notes, that figure is roughly equal to the income tax you saved by claiming the depreciation in the first place, making it essentially a wash.

Order Matters: Live First, Rent Later

The sequence — residence first, rental second — produces a dramatically different result than the reverse. If you rent the property for three years first, and then move in for two, the IRS allocates gains proportionally. Only two-fifths of the capital gains qualify for the Section 121 exclusion; the remaining three-fifths are fully taxable.

Using the same $350,000 example in reverse order, the tax bill climbs to $21,610 — more than double — even before considering whether a 1031 Exchange could defer the taxable portion. Doing it in the right order cuts that to $9,545 with no exchange required.

One Structural Requirement

To qualify for Section 121 in this strategy, you must have purchased the property in your own name or through a single-member LLC treated as a disregarded entity for tax purposes. The statute requires that you actually owned the property during the period you claim as your qualifying residence. A partnership or corporation won't satisfy that test.

Why This Is the Foundation of a Long-Term Plan

Section 121 is described here as the best section of the tax code for the individual taxpayer; Section 1031 is the best for the real estate investor. Used together across a lifetime, they can eliminate capital gains entirely in some situations and defer them indefinitely in others. The live-first, rent-later sequence is the cleanest expression of that combination — a strategy that converts an ordinary home purchase into a nearly tax-free payday with one straightforward condition: sell before the five-year clock runs out.

Not all deferred gain is taxed the same way, and the difference between the two rates can be significant. The type of property that generated the depreciation determines the rate — and a Section 1031 Exchange defers both kinds in their entirety.

Two Types of Property, Two Different Tax Rates

When you hold investment real estate, you deduct depreciation each year. That deduction lowers your taxable income while you own the property — and lowers your basis dollar for dollar. When you sell, the IRS takes some of that benefit back. The portion of your gain that came from depreciation you claimed is "recaptured" and taxed at a higher rate than the rest of your capital gain.

The rate depends entirely on what kind of property produced the depreciation.

On the building itself — Section 1250 property — recapture is taxed at a maximum of 25%. That cap applies regardless of your ordinary income bracket.

On personal property such as furniture, fixtures, and equipment — Section 1245 property, also called FF&E — the recapture is taxed as ordinary income, up to 37%. That's nearly one and a half times the rate that applies to the building. The only ceiling is the depreciation you actually took; you can't be recaptured for more than you claimed.

So if you've owned a furnished rental for a decade, you're looking at two separate recapture calculations when you sell: one at up to 25% on the building's accumulated depreciation, and one at up to 37% on the beds, appliances, and equipment you've been writing off.

What the Tax Cuts and Jobs Act Changed

Before 2018, personal property rode along inside a Section 1031 Exchange without distinction. Since January 1, 2018, the exchange applies only to real property. The FF&E is carved out — its sale is treated as a separate transaction, and any tax owed on the personal property side is due in the year of sale, not deferred.

That split means every deal now has two parts. The portion of your sales price attributable to the FF&E is a separate sale from the real estate sale. The recapture on the personal property at ordinary-income rates is no longer automatically deferred.

Bonus Depreciation as an Offset

There is a practical offset available on the personal property side. Bonus Depreciation — now 100% and permanent for property placed in service after January 19, 2025 under the One Big Beautiful Bill Act — lets you write off the full cost of qualifying short-lived assets in year one rather than over several years. It applies to furniture, fixtures, equipment, and certain improvements, not to the building itself.

Critically, it applies to used property as well, as long as the property is new to you, purchased from an unrelated party, and your basis is what you paid. This means the FF&E in a Replacement Property you acquire can generate an immediate deduction that offsets the recapture triggered on the FF&E you sold — reducing what you owe in that year, sometimes to little or nothing.

The Exchange Defers Both Kinds of Recapture

On the real estate side, a Section 1031 Exchange defers the recapture right along with the rest of the gain. The 25% recapture on the building, the underlying capital gain, even the 3.8% Net Investment Income Tax that applies to higher earners — all of it stays deferred as long as you stay in the exchange. Gain you don't recognize isn't income yet, so there is nothing for any of these taxes to attach to.

Keep exchanging, and at death your heirs take the property at stepped-up basis — the accumulated recapture and deferred gain disappear entirely.

The exchange doesn't eliminate the recapture liability; it carries it forward into the Replacement Property's lower basis. But deferral has real value — and indefinite deferral, rolled from exchange to exchange, can become permanent.

Where you hold title — and where you live — determines whether one spouse's death wipes out a lifetime of deferred tax liability or merely reduces it by half.

What Stepped-Up Basis Actually Does

IRC Section 1014 resets the basis of inherited property to its fair market value as of the date of death. That single rule is what converts decades of tax-deferred gains into tax-free wealth for heirs. But for married couples, the benefit is not automatic across the board — it depends entirely on how title is held and which state the property sits in.

The Joint Tenancy Problem

When a husband and wife hold real estate as joint tenants and one spouse dies, the survivor inherits the deceased spouse's half and that half receives a stepped-up basis. The survivor's own half, however, retains its original cost basis — every dollar of depreciation taken and every dollar of appreciation built up over the years remains embedded and fully taxable on a future sale.

Consider the math: a couple purchased a duplex for $295,000, spent $30,000 improving it, and took $50,000 in depreciation over five years, leaving an adjusted basis of $275,000. If the property is now worth $700,000 and one spouse dies, the surviving joint tenant steps up only the deceased's $350,000 share to fair market value. The survivor's $350,000 share still carries its old, depreciated basis. A sale after the death would produce a taxable gain on that surviving share — gain the couple spent years deferring through 1031 exchanges.

The Community Property Advantage

In the nine community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — the entire property receives a stepped-up basis when one spouse dies, not just the deceased's half. Both halves reset to fair market value on the date of death. Alaska gives married couples the option to achieve the same result by opting in to a community property arrangement.

That difference is enormous in practice. The same couple in a community property state who held that same $700,000 duplex could pass it to heirs — or allow the surviving spouse to sell it — with a basis equal to current fair market value. The capital gains accumulated over a lifetime of exchanges, and the depreciation recapture that would otherwise follow the property, disappear entirely.

Holding Title and Entity Structure

The full step-up is cleanest when property is held in an individual's name. When a partnership or LLC owns the property, the entity can make an IRC Section 754 election upon the death of a partner or member — that election produces a stepped-up basis for the beneficiary's interest in the property. It is still available, but it requires an affirmative election and adds complexity.

Corporations are a different matter. When a shareholder in a corporation dies, the property inside the corporation does not receive a stepped-up basis. The corporate structure blocks the benefit entirely — one more reason that partnerships and LLCs are the preferred entities for real estate held outside an individual's name.

The Lifetime Strategy

Stepped-up basis is only available for inherited property, never for purchased or gifted property — a gift transfers the donor's existing basis to the recipient, with no reset. That means the strategy requires holding the property until death, using Section 1031 exchanges to defer gains along the way. Keep exchanging, and at death your heirs take the property at stepped-up basis — the deferred tax never comes due.

Pairing Section 1031 with the stepped-up basis rules, and adding Section 121 for a primary residence, forms the ultimate lifetime investing plan. Community property titling is not a technicality — it is the difference between a partial erasure of deferred tax and a complete one.

Your basis in a rental property is not fixed at the moment you close — it moves, and after five years of claiming depreciation, it moves in exactly the wrong direction for your tax bill.

How Basis Is Built on Day One

IRC Section 1012 sets the rule plainly: the basis of purchased property is its cost. Buy that duplex for $285,000, add $10,000 in acquisition costs, and your starting basis is $295,000. Spend $30,000 on improvements before tenants move in, and basis rises to $325,000. That number is your anchor — every calculation that follows starts there.

Land Comes Out First

Not all of that $325,000 can be depreciated. The land under the building is never depreciable, so you have to separate it out before you can calculate a single year's deduction. Assign $50,000 to the lot, and what remains is a depreciable basis of $275,000. That $275,000 is spread over 27.5 years, producing an annual depreciation allowance of $10,000.

The arithmetic here is tidy by design — the underlying logic is what matters. Whatever your actual land value, the split is real and it determines every depreciation deduction you will ever take on that property.

The Quiet Shrinkage Over Five Years

Each year you rent the duplex and claim your $10,000 depreciation deduction, the IRS subtracts it from your basis. After five years and $50,000 in depreciation claimed, your basis in the property has dropped from $325,000 to $275,000. The property may be worth more than the day you bought it. Your basis is worth less. That gap — current market value minus reduced basis — is the taxable gain waiting for you if you ever sell.

This is how depreciation creates what investors call a "phantom gain." You took deductions against real rental income year by year, which was entirely legitimate. But the accounting doesn't forget. The basis reduction is permanent, and when a sale triggers it, depreciation recapture enters the picture alongside the capital gain.

The Exit That Resets Everything

A Section 1031 exchange lets you defer both the capital gain and the depreciation recapture by rolling the property into a like-kind replacement. Keep exchanging over a lifetime, and you defer the tax bill indefinitely — a tax-deferred outcome on every property in the chain.

But deferred is not the same as eliminated. The accumulated liability travels with you.

Where Tax-Deferred Becomes Tax-Free

IRC Section 1014 is where the math finally breaks in the investor's favor. When a property owner dies and leaves real estate to an heir, the basis of that property is stepped up to its fair market value as of the date of death. The compressed basis, the years of depreciation claimed, the deferred gain from every prior exchange — all of it is wiped away. The heir's new basis is whatever the property is worth on that day.

That is the transformation the source text names directly: stepped-up basis turns "tax-deferred" into "tax-free."

How You Hold Title Changes What Your Heirs Receive

The step-up is not automatic in every structure. In Community Property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — a surviving spouse who inherits the property receives a stepped-up basis on the entire property, including the share they already owned. In a Joint Tenancy state, only the deceased spouse's share steps up; the survivor's original cost basis stays put.

For property held in an LLC or partnership, a Section 754 election made upon a partner's death allows the entity to step up the basis of the property for the beneficiary. Corporations offer no equivalent — a shareholder's death does not step up the basis of corporate property.

The structure you choose today determines what your heirs inherit tomorrow — a full step-up, a partial one, or none at all.

When you receive real estate as a gift, you inherit the donor's tax problem along with the deed. IRC Section 1015 locks your basis to whatever basis the donor held — no reset, no step-up, no relief from years of accumulated depreciation.

What Basis Means Before We Go Further

Every piece of real property you own carries a basis — a number that determines your gain when you eventually sell. For purchased property, IRC Section 1012 sets that number at cost: what you paid, plus acquisition costs, plus improvements, minus depreciation claimed over time. A duplex purchased for $285,000 with $10,000 in closing costs starts at a $295,000 basis. Add $30,000 in improvements and it reaches $325,000. Claim five years of depreciation at $10,000 per year and the basis falls to $275,000. That figure — not the current market value — is what determines your taxable gain on a sale.

Section 1015: Carryover Basis Is the Rule for Gifts

IRC Section 1015, "Basis of Property Acquired by Gifts and Transfers in Trust," states that if property was acquired by gift, "the basis shall be the same as it would be in the hands of the donor or the last preceding owner by whom it was not acquired by gift." The statute goes on to add one narrow exception: if the donor's basis exceeds fair market value at the time of the gift, the recipient uses fair market value — but only for determining a loss, not a gain.

In plain terms, the recipient steps into the donor's shoes. If the donor bought a building decades ago, claimed years of depreciation, and now holds a basis far below market value, the person who receives that building as a gift carries the same beaten-down basis forward. The gift transfers both the asset and the embedded tax liability. Property worth $900,000 with a donor basis of $175,000 means the recipient faces a $725,000 gain the moment they sell — regardless of what they paid for the gift, which was nothing.

This is sometimes called "carryover basis" or "transferred basis." The "transferred basis" is not entirely precise terminology in tax usage, but the concept is clear: basis does not reset at the moment of the gift.

Section 1014: The Step-Up That Gifted Property Does Not Get

IRC Section 1014 — the provision that turns "tax-deferred" into "tax-free" — applies exclusively to inherited property. It provides that the basis of a decedent's property in the hands of an heir is reset to fair market value as of the date of death. That step-up wipes out decades of deferred capital gains and depreciation recapture in a single event.

Gifted property never touches Section 1014. The step-up is reserved for property that passes through death, not property transferred during life by deed or gift. These two code sections operate in entirely different worlds — and confusing them is an expensive mistake.

The Practical Gap Between a Gift and an Inheritance

The difference between receiving property as a gift versus inheriting it can be the difference between a clean slate and a six-figure tax bill. Keep exchanging through a 1031, hold the property, and at death your heirs take the property at stepped-up basis — the gain accumulated over a lifetime of deferral disappears. Transfer that same property as a gift before death and the recipient is stuck with every dollar of deferred gain still embedded in the basis.

Holding structure at death also matters. Property held outright by one individual passes most cleanly. Spouses in community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — can receive a step-up on the entire property when one spouse dies, not just the deceased spouse's share. Joint tenancy outside community property states steps up only the decedent's portion. Partnerships and LLCs can preserve the step-up through an IRC Section 754 election upon a partner's death. Corporations get no step-up at all.

None of those paths are available to the recipient of a gift. Section 1015 leaves them exactly where the donor stood — and the donor's basis is the number that counts.

The name on the deed to your Replacement Property must be identical to the name on the deed to the Relinquished Property you sold. Get that wrong at closing and you risk losing the exchange entirely.

Why the Title Match Is Non-Negotiable

When you sell your Relinquished Property and then purchase your Replacement Property, you are the same Exchangor throughout. The IRS treats the transaction as a continuous exchange by a single taxpayer — so the entity or individual taking title at the end must be the same entity or individual that held title at the beginning. It doesn't matter how clean the rest of your exchange is: the 45-day identification window, the 180-day closing deadline, the equal-or-greater value and equity rules. If the vesting on the Replacement Property deed diverges from the vesting on the Relinquished Property deed, the structural requirement fails.

This catches people at the closing table because buyers and sellers routinely adjust vesting for estate-planning or financing reasons without thinking twice. In a 1031 exchange, you don't have that flexibility.

Who the "Exchangor" Actually Is

The Exchangor is the owner of the appreciated investment or business property who wants to defer capital gains and depreciation recapture by completing a like-kind exchange. You could be an individual or you could be an LLC, a partnership, a corporation, or any other business entity. Whichever form you take, that form must remain consistent from the Relinquished Property deed to the Replacement Property deed.

The Single-Member LLC Disregarded Entity Exception

There is one recognized exception: a single-member LLC that is treated for tax purposes as a disregarded entity.

A disregarded entity is not recognized as a separate taxpayer from its sole member. Because the IRS looks through the LLC to the individual behind it, the title mismatch between the individual's name and the LLC's name — or vice versa — does not necessarily create a different taxpayer for exchange purposes. The individual and the single-member disregarded LLC are, for tax purposes, the same person.

What matters for closing-day purposes is that this exception is narrow: it applies only to a single-member LLC with disregarded-entity status. A multi-member LLC, a partnership, or a corporation does not qualify for this carve-out. If you are thinking of using an entity structure that differs from the one on your Relinquished Property deed, confirm that it fits squarely within the disregarded-entity exception before you get to the closing table — not after.

What the Replacement Property Rules Already Require

The title-match rule sits on top of the other requirements for Replacement Property. The property must be real property — the Tax Cuts and Jobs Act of 2018 ended the ability to exchange personal property such as furniture, fixtures, and equipment (FF&E) on a tax-deferred basis. The Replacement Property must be the type of property you can hold for investment or business purposes after you purchase it; what the current owner is doing with it is irrelevant. You can buy one Replacement Property or several. But every one of those properties must be titled in the same name that appeared on the Relinquished Property deed.

The Practical Takeaway

Vesting is a closing mechanic that feels administrative until it isn't. Confirm the exact name on your Relinquished Property deed before you identify Replacement Properties, share that name explicitly with the title company handling the Replacement Property closing, and verify the draft deed before you sign. The single-member disregarded-entity exception exists, but it is the only exit from the identical-vesting requirement the source text recognizes — and relying on it without confirming your LLC actually qualifies is a risk no exchange should carry into closing.

Selling a furnished rental splits into two transactions the moment you close — one for the real estate, which your 1031 exchange can shelter, and one for the furniture, fixtures, and equipment, which it cannot. That second transaction triggers depreciation recapture, and the bill can be steep. Bonus Depreciation under the One Big Beautiful Bill Act is the most direct tool available to offset it.

Why FF&E Is Now Outside the Exchange

Before 2018, personal property rode along inside a Section 1031 exchange without distinction. The Tax Cuts and Jobs Act ended that. Since January 1, 2018, Section 1031 applies to real property only — the building, the land, and what is legally attached to them. Everything else in the deal — beds, refrigerators, window units, washers, dryers — is FF&E, and FF&E is personal property. When you sell, the portion of the sales price attributable to the FF&E is treated as a separate sale, entirely outside the exchange. Whatever tax is due on that separate sale must be paid now, not deferred.

What Depreciation Recapture Means for FF&E

Each year you held the rental, you deducted depreciation on the FF&E — a paper loss that lowered your taxable income and, dollar for dollar, lowered your basis in those assets. When you sell, the IRS takes some of that benefit back. The portion of your gain that came from depreciation you already claimed is "recaptured." On personal property like furniture and equipment — Section 1245 property — recapture is taxed as ordinary income, at rates up to 37%, though never more than the depreciation you actually took. A 1031 exchange defers recapture right along with the rest of the gain on real estate, but since FF&E no longer qualifies, its recapture is exposed and taxable in the year of sale.

How Bonus Depreciation Enters the Picture

Here is where the OBBBA changes the math. Normally you write off the cost of shorter-lived property a little at a time over several years. Bonus Depreciation lets you write off the entire cost in the first year instead. Under the One Big Beautiful Bill Act, that deduction is 100% and permanent for property placed in service after January 19, 2025. It applies to the shorter-lived assets — furniture, fixtures, equipment, and certain improvements — not to the building itself, which is real property and depreciates on the slow schedule.

The practical effect: when you buy your replacement property and it comes with FF&E, you can elect to expense the full cost of that FF&E in year one. That first-year deduction generates a loss — or at minimum reduces your taxable income — in the same year you recognize the recapture from selling the relinquished FF&E. The deduction on the new FF&E can offset, or even eliminate, the recapture tax on the old FF&E.

Used Property Qualifies — Which Matters for Almost Every Deal

Most furnished rentals are not bought new. The OBBBA does not require new property. Used FF&E qualifies for 100% Bonus Depreciation as long as three conditions are met: the property is new to you, you bought it from someone unrelated to you, and your basis in it is what you paid — not a carryover basis from a prior owner. In a typical rental acquisition, all three conditions are satisfied. The seller of the replacement property is an unrelated third party, the FF&E is property you have never owned before, and you are paying fair market value for it.

The Mechanics in Plain Terms

When you close on your replacement property, allocate the purchase price between the real estate and the FF&E — the same allocation exercise you performed on the sale side. The real estate portion flows into your 1031 exchange. The FF&E portion is a separate purchase, and if the property was placed in service after January 19, 2025, you can deduct 100% of that cost in the year of purchase. Set that deduction against the ordinary income generated by recapture on the FF&E you just sold, and the two positions can net to near zero.

When a shareholder in a C corporation dies, the deferred gain locked inside the corporation's real estate does not die with them — it survives, untouched, because corporate property receives no stepped-up basis at a shareholder's death. Partnerships and LLCs face no such trap: by making an IRC Section 754 election at the death of an owner, those entities can step up the basis of the underlying property in the hands of the beneficiary, turning a lifetime of tax deferral into permanent tax elimination.

What Basis Actually Means

Every piece of real estate you own has a basis — the number that determines your gain when you eventually sell. For purchased property, IRC Section 1012 sets the starting point at cost: purchase price plus acquisition costs plus improvements, minus depreciation claimed over the years. Buy a duplex for $285,000, spend $10,000 closing it and $30,000 improving it, and your basis opens at $325,000. Rent it out, and the depreciation clock runs. After five years of $10,000 annual depreciation on a $275,000 depreciable basis, that number has fallen to $275,000 — and every dollar of depreciation claimed becomes recapture exposure when you sell.

Gifted property offers no relief. Under IRC Section 1015, the recipient simply inherits the donor's basis — the accumulated gain and recapture travel with the property as if nothing happened.

The Step-Up: IRC Section 1014

Inherited property is different. IRC Section 1014(a) resets the basis of a decedent's property to its fair market value as of the date of death. Every dollar of deferred capital gain and every dollar of depreciation recapture that built up over a lifetime disappears. Tax-deferred becomes tax-free. That reset is the payoff for a strategy built around 1031 exchanges: keep exchanging, and at death your heirs take the property at stepped-up basis — the accumulated gain vanishes entirely.

The mechanism is straightforward when a single individual owns property in their own name. The complexity begins the moment a business entity is involved.

Partnerships and LLCs: The 754 Election

For real estate held in a partnership or LLC, the step-up does not happen automatically — but it is available. By making an IRC Section 754 election at the death of an owner, the partnership or LLC steps up the basis of the entity's property in the hands of the beneficiary. The gain that would otherwise survive the owner's death is extinguished at the entity level.

An LLC has flexibility here. It can elect to be treated as a disregarded entity or as a partnership for tax purposes — either way, the 754 election remains accessible. The one thing an LLC cannot do is elect to be treated as a C corporation if it wants to preserve this path.

C Corporations: The Structure That Forfeits the Exit

A C corporation provides no equivalent mechanism. When a shareholder dies, the corporation's real estate keeps its existing inside basis unchanged. The shareholder's stock may receive a stepped-up basis in the heir's hands, but the gain embedded in the property itself — capital gain and depreciation recapture accumulated over decades — remains alive inside the entity. There is no election, no workaround, no equivalent to Section 754. Holding real estate inside a C corporation is the one structure that permanently forecloses this exit.

The Spousal Angle

How much of the estate receives the step-up at death also depends on how spouses hold title. In a joint tenancy, only the deceased spouse's share steps up — the survivor's original cost basis stays put. In the nine community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), the entire property steps up at the first spouse's death, not just the decedent's half. Alaska allows spouses to opt into a community property arrangement as well.

The Full Lifetime Plan

Stepped-up basis is most powerful as the final act of a deliberate strategy. Section 1031 defers gain through every exchange. Section 121 shelters gain on a primary residence. And Section 1014 — combined with the Section 754 election where an entity holds the property — eliminates whatever remains at death. Holding real estate in a partnership or LLC preserves access to all three.

Basis is what you paid for your investment property, plus capital improvements, minus depreciation taken. Get that number right and the rest of the tax calculation follows mechanically; get it wrong and every figure downstream — gain, recapture, total tax — is wrong too.

The Formula in Plain Terms

Basis equals purchase price, plus capital improvements, minus allowable depreciation. That's it. Three inputs. But each one moves the final number, and the interactions between them are what catch investors off guard.

Building the Number Through the Examples

The Taxpayer bought a duplex for $200,000 cash. He made no improvements and claimed $65,400 in straight-line depreciation over ten years. His basis:

$200,000 − $65,400 = $134,600

He sells for $400,000. Capital gains is the difference between the sales price and basis — $400,000 minus $134,600 — so his gain is $265,400. That single basis figure drives everything.

Now change one input. Adams added garages to each unit at a cost of $30,000, then depreciated those improvements straight-line, claiming an additional $7,644. His total depreciation is now $73,044. His basis:

$200,000 + $30,000 − $73,044 = $156,956

Same sales price of $400,000. But now his capital gains is $243,044 — a different number entirely, because basis shifted. The formula didn't change; the inputs did.

Why Depreciation Cuts Both Ways

Depreciation feels like a pure benefit while you hold the property — it reduces taxable income year after year. But it also erodes basis dollar for dollar. Every $1 of depreciation claimed today lowers basis by $1 and increases the gain you'll eventually recognize by $1.

In the basic example, the Taxpayer's true economic profit was $200,000 — he paid $200,000 and sold for $400,000. But his computed capital gains was $265,400, because $65,400 of depreciation had already reduced his basis below what he paid. That $65,400 is not phantom money; it represents deductions he already received, and the IRS collects on them at sale through depreciation recapture — taxed at a maximum rate of 25%, separate from the 20% rate on true capital gains.

In the expanded example, total depreciation is $73,044 (garages included), and that entire amount faces recapture. The tax on it: $73,044 × 25% = $18,261. The remaining $170,000 of true capital gain — the difference between what he received ($400,000) and what he actually spent ($230,000, counting both the purchase and the improvements) — is taxed at 20%, producing $34,000. Total tax: $52,261.

What Doesn't Change Basis

Two things that investors commonly believe affect the math actually don't. It makes no difference whether the Taxpayer paid cash for the property or borrowed most of the purchase price. He paid $200,000 for the duplex — full stop. Likewise, it makes no difference whether the $30,000 for the garages came from savings or a home-improvement loan. The source of the money is irrelevant; the amount spent on the property is what counts. Loan balances paid off at closing reduce net proceeds, not taxable gain.

The Downstream Consequence

Because basis drives gain, and gain drives the split between capital gains tax and recapture tax, a small error in the basis calculation compounds across every line that follows. Add a capital improvement you forgot to record and basis goes up — gain goes down. Miss a year of depreciation in your records and basis is overstated — the IRS may disagree with your gain figure entirely.

For the Taxpayer, in the final scenario, his basis is $156,956. His capital gains is $243,044. His total federal tax bill is $52,261. Every one of those numbers is a direct output of the same three-input formula. The formula is simple; the discipline of tracking each input accurately over a ten-year hold is where the work actually lives.

Renting a property for three years before moving in costs you more than twice the taxes of the reverse approach — on the same sale price, the same property, the same five-year window. The order in which you occupy a home isn't a technicality; it's the lever that controls your entire tax outcome.

The Rule Behind the Numbers

Section 121 allows a taxpayer to exclude capital gains on a primary residence lived in for two out of the five years prior to sale — up to $250,000 for a single filer, $500,000 for a married couple. The critical language is "two out of five years." You don't have to be living there at the moment of sale. That flexibility is where strategy lives.

Live First, Rent Later: The Full Exclusion

Buy a $350,000 home, live in it for two years, then rent it out for three. Sell it just before the five-year window closes at $484,050 — a 6.7% annual appreciation rate.

Your total gain is $134,050 in true capital gains, plus $38,182 in depreciation taken during the three rental years. Under Section 121, all $134,050 of capital gains is excluded — including gains that accrued during the rental period, while you weren't living there at all. The only tax owed is the 25% depreciation recapture on the $38,182 you claimed: $9,545, and nothing more.

That recapture amount is roughly equal to the income tax you saved by claiming depreciation in the first place, making it close to a wash. The capital gains tax that would have applied to $134,050 at a 15% rate — roughly $20,000 — disappears entirely.

Rent First, Live Later: The Prorated Exclusion

Now reverse the sequence. You buy the same $350,000 property, rent it out for nearly three years, then move in and live there as your primary residence for two years. Same sale price: $484,050. Same total gain: $134,050.

The IRS doesn't care that you eventually lived there — it prorates the exclusion based on how many of the five years you actually used the property as your primary residence. Two years out of five is 40%. You exclude 40% of the capital gains: $53,620. The remaining $80,430 is taxable.

At a 15% capital gains rate, that's $12,065 in capital gains tax. Add the 25% depreciation recapture on the same $38,182 — another $9,545. Total tax bill: $21,610.

Same property. Same holding period. Same sale price. More than double the taxes — because you rented first.

Why the IRS Treats These Scenarios Differently

In the live-first scenario, the two-year residency requirement is met before the rental period begins. Section 121's exclusion covers the full appreciation over all five years, not just the portion that accrued while you were living there. The rental years ride along inside the exclusion window at no additional tax cost beyond recapture.

In the rent-first scenario, the IRS requires you to allocate gain proportionally across the ownership period. Only the fraction of time you occupied the property as a primary residence — two-fifths — shields a corresponding fraction of the gain. The rest is ordinary taxable capital gain.

One Structural Requirement Worth Knowing

To use the 121 and 1031 combination at all, the property must be held either in your own name or in an LLC treated as a disregarded entity for tax purposes. This satisfies Section 121's requirement that you actually owned the property during the five-year period. A standard multi-member LLC or a corporation won't qualify.

The Sequence Is the Strategy

The source text puts it plainly: the rent-first scenario "compares to paying $9,545 for doing the same thing, only in reverse order." That $12,065 difference — $21,610 versus $9,545 — comes entirely from which two years inside the five-year window counted as your residence. If you have flexibility in when you move in versus when you rent, the math strongly favors living there first. And if you still owe taxes after applying Section 121, a Section 1031 exchange can defer the tax on the remaining taxable gain.

Stepped-up basis is what turns "tax-deferred" into "tax-free" — and when you combine it with Section 121 and Section 1031, you have a lifetime investing strategy that shelters gains on a primary residence, defers gains on every investment property you ever sell, and then wipes the slate clean at death.

How Basis Works Before the Step-Up

To understand why the step-up matters, you need to know what basis is and how it erodes. When you buy a duplex for $285,000 with $10,000 in acquisition costs, your basis starts at $295,000. Spend $30,000 improving it and basis rises to $325,000. But then you start depreciating — and depreciation works against you. With $50,000 assigned to non-depreciable land, you have a depreciable basis of $275,000, spread over 27.5 years: $10,000 per year. After five years of rental income, you've claimed $50,000 in depreciation and your basis has fallen to $275,000. Every dollar of depreciation claimed is a dollar of gain waiting to be taxed when you sell — at depreciation recapture rates, not ordinary capital gains rates.

That's the problem Section 1031 was built to solve.

What Each Tool Does That the Others Cannot

Section 121 shelters gain on a primary residence — up to the limits the code allows. It does one job well and nothing else. It won't help you on investment property.

Section 1031 defers capital gains and depreciation recapture when you sell investment property and replace it with like-kind investment property. Keep exchanging, and the deferred gain rides along inside every replacement property you acquire. The tax bill grows, but it never comes due as long as you keep exchanging. Section 1031 cannot touch your primary residence.

Stepped-up basis — governed by IRC Section 1014 — resets the basis of inherited property to its fair market value as of the date of death. Whatever deferred gain was locked inside the property simply disappears. The heir's basis is the value on the day they inherit it, not the original purchase price minus decades of depreciation. This is the only tool that eliminates tax liability rather than deferring it, and it is only available for inherited property — not purchased property, not gifted property.

The Gifted-Property Trap

Gifting property does not trigger a step-up. Under IRC Section 1015, a recipient of gifted property takes the same basis the donor had — the carryover basis. If your basis has been ground down by years of depreciation, you hand that problem directly to the person you're trying to help. The step-up only arrives through inheritance.

How Title and Entity Choice Determine What the Heirs Actually Receive

The step-up isn't automatic in every situation — how you hold title matters enormously.

In a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — plus Alaska by opt-in), when one spouse dies, the entire property receives a stepped-up basis, including the surviving spouse's own share. In a joint tenancy arrangement outside those states, only the deceased spouse's share steps up; the survivor's share retains its cost basis.

Corporations are a dead end for this purpose — when a shareholder dies, the property inside a C corporation receives no step-up. Partnerships and LLCs, on the other hand, can make an IRC Section 754 election at the death of a partner or member, allowing the entity's property to receive a stepped-up basis in the hands of the beneficiary. This is why holding investment real estate in an LLC or partnership — rather than a corporation — is a meaningful structural decision, not just a liability question.

The Lifetime Plan in Sequence

Live in a home, sell it, shelter the gain under Section 121. Roll the proceeds into investment property and defer the gain through Section 1031 exchanges — once, or a dozen times over a career. Each exchange resets the clock without triggering tax. At death, the heirs inherit the final replacement property at its fair market value on that date. The accumulated deferred gain — capital gains and depreciation recapture built up over a lifetime — is extinguished. Tax-deferred becomes tax-free.
