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.
