You Owe Tax on Depreciation You Never Took
Short answer: When you sell a rental, the IRS taxes you on depreciation you were “allowed or allowable” to take — that is, the depreciation you could have claimed, whether or not you actually did. So if you skip depreciation to keep your returns simple, you don’t dodge the tax. You lose the yearly deduction and still owe recapture at sale. It’s one of the few places in the tax code where doing nothing costs you twice. (This is educational, not tax advice — see a licensed CPA/EA for your situation.)
The rule that surprises landlords
Depreciation is the deduction that makes rental property so tax-efficient. The IRS lets you treat the building (not the land) as slowly wearing out, deducting a slice of its cost every year — 27.5 years, straight-line, for residential rental property. On a paper-profitable rental, that deduction often turns taxable income negative even while your bank account grows.
Here’s the part almost nobody expects. That deduction isn’t really optional.
When you sell, the IRS reduces your cost basis — the number you subtract from the sale price to figure your gain — by the depreciation you were entitled to take. The statutory phrase is “allowed or allowable.” Allowed is what you actually deducted. Allowable is what you could have deducted under the code. The IRS uses the greater of the two.
Translation: skip depreciation, and the IRS still acts as if you took it when it calculates your gain. You gave up years of deductions and your tax bill at sale is exactly the same.
What recapture actually costs
The portion of your gain that comes from depreciation gets its own tax treatment: unrecaptured Section 1250 gain, taxed at a federal rate of up to 25% — higher than the long-term capital-gains rate on the rest of the profit.
Walk it through. Say you hold a rental for a decade and were allowed roughly $80,000 of depreciation over that time.
- If you claimed it: you got ~$80,000 of deductions across ten years, then pay recapture (up to 25%) on that amount at sale. Fair trade — you banked the benefit.
- If you didn’t claim it: you got nothing for ten years, and you still pay recapture on the full ~$80,000, because it was “allowable.” Pure loss.
Same tax at the finish line. Only one path gave you the deduction along the way.
Why this is really a bookkeeping story
The reason owners miss depreciation isn’t laziness — it’s records. To depreciate correctly you need a clean fixed-asset schedule for each property: original purchase price, the split between land and building, every capital improvement added to basis, and depreciation taken to date. Miss that, and either your preparer can’t claim the deduction or nobody’s tracking basis — and basis is exactly what recapture is calculated against.
This is where per-property books stop being paperwork and start being money. The same discipline that produces a per-property P&L is what keeps a defensible depreciation schedule — so the deduction is claimable every year and the recapture math is right (not guessed) at sale.
And if you’ve already missed years of it? There’s usually a fix — IRS Form 3115, a change in accounting method that lets you catch up missed depreciation without amending a stack of old returns. It’s a specialist filing, which is exactly why this belongs with a licensed CPA/EA — not a DIY spreadsheet.
The reframe
Most owners think of bookkeeping as recording what already happened. Depreciation recapture flips that: the IRS has already decided you’re depreciating the building, whether your books reflect it or not. Your only choice is whether you capture the benefit on the way or hand it back at the end for nothing.
That’s the quiet case for treating your books as infrastructure, not a tax-season chore. DaxHive keeps per-property books and a proper depreciation schedule — accurate, current, and tax-ready — while filing and any depreciation or recapture strategy run through licensed CPA/EA partners.

Frequently asked questions
Do you owe depreciation recapture if you never claimed depreciation? +
Generally yes. The IRS calculates recapture on depreciation allowed or allowable, meaning the amount you were entitled to claim whether or not you actually did. Skipping the deduction does not avoid the tax; it usually means you lose the yearly write-off and still owe recapture when you sell. This is not tax advice; confirm your situation with a licensed CPA or EA.
What does allowed or allowable depreciation mean? +
Allowed means the depreciation you actually deducted on your returns; allowable means the depreciation you could have deducted under the tax code. When you sell, the IRS reduces your cost basis by the greater of the two, so unclaimed depreciation still lowers your basis and raises your taxable gain.
What is unrecaptured Section 1250 gain? +
Unrecaptured Section 1250 gain is the part of your profit on a real property sale that comes from depreciation you took or could have taken. For most rental property it is taxed at a federal rate of up to 25 percent, separate from the lower long-term capital gains rate that applies to the rest of the gain.
How long do you depreciate a residential rental property? +
Residential rental property is depreciated over 27.5 years using straight-line depreciation on the building value, not the land. That means you deduct roughly one twenty-seventh-and-a-half of the building's cost each year while you hold it as a rental.
Can you fix missed depreciation from past years? +
Often yes. The usual route is IRS Form 3115, a change in accounting method that lets you claim the catch-up depreciation you missed, rather than amending years of returns. It is a specialist filing, so it should be done through a licensed CPA or EA, but it can recover deductions you left on the table.
Why does depreciation reduce my cost basis? +
Depreciation is a deduction for wear on the building, so each year you claim it your remaining investment on the books, your basis, drops by that amount. Because basis is what you subtract from the sale price to figure gain, a lower basis from years of depreciation means a larger taxable gain when you sell.
Does a 1031 exchange avoid depreciation recapture? +
A properly structured 1031 like-kind exchange can defer both capital gains and depreciation recapture into the replacement property, not erase them. The deferred amounts carry forward, so the tax generally comes due when you eventually sell without exchanging. Whether you qualify is a determination for a licensed CPA or EA.
How does good bookkeeping help with depreciation? +
Clean books keep a depreciation schedule and fixed-asset record for each property, tracking original cost, the split between land and building, improvements, and depreciation taken to date. That record is what lets your CPA claim the deduction correctly each year and calculate recapture accurately at sale instead of guessing.
Is skipping depreciation ever a good idea for a landlord? +
Rarely, because the recapture rule means you usually pay the tax at sale whether or not you took the deduction. Choosing to skip it typically forfeits years of tax savings for no benefit. There are narrow planning situations, but they are a licensed CPA or EA call, not a default.
Does depreciation recapture apply to house flips? +
Usually not in the same way, because property held mainly for resale is inventory rather than a depreciable rental asset, so flippers generally do not depreciate it and profit is taxed as ordinary income. The recapture trap specifically bites buy-and-hold rental owners who depreciate the building over time.
Does DaxHive give tax advice on depreciation? +
No. DaxHive keeps your per-property books and depreciation schedule accurate and tax-ready, and the filing and any depreciation or recapture strategy are handled through licensed CPA or EA partners. You get clean records that make the deduction claimable and the recapture calculation correct; the tax determinations stay with the licensed professional.
