Depreciation Recapture on Rental Property, Calculated

Depreciation is the best deduction in rental real estate, and it comes with a tab. Every year you deduct 1/27.5 of your building's basis against rent. When you sell, the IRS collects on those years of deductions: the slice of your gain created by depreciation is taxed at your ordinary rate, capped at 25%, before the friendlier capital gains rates touch anything. That slice is depreciation recapture, formally unrecaptured Section 1250 gain.

Most guides define it and stop. The parts that actually cost people money are the ones they skip: recapture applies even if you never claimed the depreciation, the 25% is a ceiling and not a flat rate, and in the right situation the recapture bill is beatable with losses you already own. Here is the practitioner version, with the math.

The three-number calculation

Recapture needs three numbers you already have (or your bookkeeping should have):

1. Adjusted basis = purchase price + capital improvements − accumulated depreciation.
2. Total gain = net sale price (after selling costs) − adjusted basis.
3. Recapture layer = the smaller of accumulated depreciation or total gain, taxed at your ordinary rate up to 25%. The rest of the gain is long-term capital gain at 0/15/20%.

Notice what depreciation does to the math twice: it lowered your basis (which makes the gain bigger), and then that depreciation-sized slice of the gain gets the worse rate.

A worked example: the $500,000 sale

Say you bought a rental for $400,000, put $25,000 of capital improvements into it, and claimed $100,000 of depreciation over the years you held it. You sell for $500,000 net of selling costs.

Line	Amount
Purchase price	$400,000
+ Capital improvements	$25,000
− Accumulated depreciation	($100,000)
Adjusted basis	$325,000
Net sale price	$500,000
Total gain	$175,000
Recapture layer (lesser of $100,000 depreciation or $175,000 gain)	$100,000 at up to 25% → up to $25,000
Remaining long-term gain	$75,000 at 15% → $11,250
Federal tax on the sale (before state, before NIIT)	up to $36,250

Two things people miss in this table. The recapture layer is the lesser of depreciation or gain: if the property had only gained $60,000, the whole gain would be recapture and there would be no 15% layer at all. And the 25% applies only if your ordinary bracket is at least that high; a 22%-bracket seller pays 22% on the layer. High earners also add the 3.8% net investment income tax on top of both layers.

If you want this math on your own numbers before you list the property, our rental depreciation calculator tracks the accumulated total, and the sell vs hold vs 1031 calculator runs the full sale waterfall including the recapture layer.

The trap: "allowed or allowable"

The most expensive misunderstanding in this area: you owe recapture on the depreciation you were entitled to take, whether or not you took it. The IRS phrase is allowed or allowable. Your basis is reduced by the allowable depreciation either way.

So a landlord who never claimed depreciation, and there are more of them than you would think, gets the worst of both sides: no deductions during the holding years, full recapture bill at sale. Skipping depreciation does not opt you out. It just donates the annual deduction back.

If that is you, the fix before selling is Form 3115 (change in accounting method), which lets you catch up all the missed depreciation as a one-year deduction under a Section 481(a) adjustment. Catching up turns phantom recapture into real deductions first. This is worth a conversation with your CPA well before the sale closes, not after.

Three legal ways to shrink the bill

1. A 1031 exchange defers it (and the basis follows you)

A 1031 exchange defers the whole gain, recapture layer included. What actually happens mechanically: your old adjusted basis and your accumulated depreciation carry into the replacement property. The recapture is not erased, it rides along, and it comes due when you eventually sell without exchanging. Hold until death and the stepped-up basis erases the deferred gain and the recapture with it. That is the fine print of "swap till you drop."

The carryover also means your depreciation schedule on the new property starts from the carried basis, not the new purchase price, so your annual deduction is smaller than a fresh buyer's would be. Deferral is a loan from the IRS, and the collateral is your future depreciation.

If the property was ever your home, or you plan to live in the replacement someday, the exchange picks up extra clocks: can you 1031 a primary residence walks the convert-first safe harbor and the Section 121 stack, the one combination that turns part of a deferred gain into an excluded one.

2. Suspended passive losses release at sale

If your rental ran paper losses you could not deduct (the passive activity rules park them), those suspended losses release in full the year you sell in a fully taxable sale. They deduct against everything, including the recapture layer.

This is first-hand for us: on a real two-property portfolio we keep books for, roughly $206,589 of suspended passive losses had built up over the holding years. Run through the sale math, the losses releasing on an outright sale were worth more than the deferral a 1031 would buy. The instinct said exchange; the spreadsheet said sell. If you carry Form 8582 losses, the recapture layer is often much less scary than it looks, because the release offsets it dollar for dollar.

3. Keep small purchases out of basis in the first place

Recapture only applies to costs you capitalized and depreciated. Anything you expensed under the de minimis safe harbor election (generally items at or under $2,500) never enters basis, so there is nothing to recapture on it at sale. The $2,200 refrigerator you expensed in year two is a closed file; the same refrigerator capitalized would be sitting in your accumulated depreciation total waiting for the 25% layer. Expensing small items is recapture avoidance you do years in advance, one receipt at a time.

Where it lands on the return

The sale goes on Form 4797 (Sales of Business Property). The unrecaptured Section 1250 gain flows through the Schedule D worksheet to your 1040. The input that makes all of it accurate is boring: your accumulated depreciation total, straight off the depreciation schedules you have (or have not) been keeping since the year the property was placed in service.

That number is exactly the kind of thing that quietly rots in a spreadsheet. Our books track it per property, per asset, from the annual depreciation schedule through the sale waterfall, so the recapture math at exit uses the same numbers the returns claimed along the way.

The takeaway

Depreciation recapture is not a reason to skip depreciation, and it is not a flat 25% haircut. It is a known, computable layer: lesser of depreciation or gain, at your ordinary rate capped at 25%. You beat it in advance (de minimis expensing, catching up missed depreciation with Form 3115), at the exit (1031 deferral if the math favors it), or with what you already own (suspended losses releasing at sale). The one thing that makes every option work is an accurate accumulated depreciation number, kept current from year one. For what that number typically looks like at 5, 10, and 20 year holds, and the maximum bill each implies, see the depreciation data tables. Run your own sale both ways before assuming the exchange wins; ours did not.
