Selling Your STR on Installments: What Gets Deferred, and What Doesn't

The promise, and the catch

The appeal of an installment sale is simple. Instead of taking the whole price at closing and recognizing the whole gain in one year, you let the buyer pay you over time — and you generally recognize the gain over time, too, as the payments come in. Spreading recognition across tax years changes the timing of the taxable gain; whether that actually reduces your total tax depends on your facts. That timing shift is real, and it's why §453 exists.

The catch is the part the pitch leaves out. Not all of your gain spreads with the payments. One specific slice — the income tied to the depreciation you've been claiming all along — can be pulled forward into the year of the sale even though most of the money is still years away. For a short-term-rental owner who has been aggressive with depreciation, that slice can be large enough to turn a "spread the tax" plan into a year-one cash-flow problem. Understanding which piece accelerates, and why, is the whole point of this page.

(This guide assumes the sale otherwise qualifies for installment reporting; §453 has its own eligibility rules and exceptions — and you can elect out of the method — which your tax professional should apply to the actual transaction.)

What an installment sale actually spreads

Under §453, the mechanic is a gross-profit percentage. It determines how much of each qualifying principal payment you receive is reported as installment-sale gain — so each year you recognize a proportional slice of the gain as the cash arrives, rather than all of it at closing. (P53 owns how basis is built; the actual Form 6252 percentage is a computation for your tax professional, since it folds in more than basis alone.) That deferral of the gain eligible for installment reporting is the genuine benefit of the structure.

Two things sit outside that spread and are worth separating out now, because conflating them is where owners get surprised:

• Interest is not gain. If you're financing the sale, the note charges interest, and that interest is ordinary income taxed as you receive it — a separate line from the gain (more on it below).
• Depreciation recapture is not spread. This is the big one, and it has its own rule.

The recapture trap: depreciation lands in year one

Here's the rule that breaks the "spread it all" story. Under §453(i), the depreciation-recapture income — the ordinary-income portion attributable to depreciation you've taken — is generally recognized in the year of the sale, in full, and it does not get reported on the installment method. It jumps the queue: because that income is recognized up front, it can create a real tax bill in year one even though you've collected only the first installment.

Who this hits, and how hard, depends on how you depreciated — and the pieces are different, so keep them distinct:

• If you ran a cost-segregation study, you carved out shorter-life components (think 5-, 7-, and 15-year property). The depreciation on those is subject to §1245 ordinary recapture, and that recapture is exactly what §453(i) pulls into the year of sale. The operator who accelerated deductions with cost seg — often the same reader P51 and P47 sent here — is the one most likely to face a real cash tax bill in year one.
• A building depreciated on the ordinary straight-line schedule typically generates little or no §1250 ordinary recapture, so §453(i) may accelerate little on that piece.
• Separately, there is often unrecaptured §1250 gain — a capital-gain category (not recapture in the ordinary-income sense) tied to prior building depreciation. That is not §453(i) recapture income; as capital gain it can generally still be reported across the installments. Whether and how each of these pieces applies to your sale is character-level detail this page deliberately routes to Depreciation Recapture at Sale (P54) and the Exit-Tax Anatomy page rather than working out here.

The plain-English takeaway: an installment sale can spread the gain that's eligible for installment reporting, but the ordinary depreciation-recapture income is generally recognized up front — in the year of sale. That recognition can create a substantial year-one tax liability even when most of the price is still unpaid, so model that number with your tax professional before you agree to installment terms — it's the difference between a smooth plan and a surprise.

The interest you charge is ordinary income

An installment note isn't just a way to spread gain — it's a loan, and loans carry interest. Whatever interest the buyer pays you is ordinary income, taxed as you receive it, wholly separate from the gain calculation above. And you don't get to make the interest disappear by not charging any: if the note's stated rate is too low, the rules under §483 and §1274 generally impute interest, recharacterizing part of what you thought was principal as interest income. Either way, a chunk of your annual receipts is ordinary income, separate from the installment-sale gain — plan for it, and let your tax pro run the imputed-interest rules against your actual note terms.

You just became the bank

The quiet consequence of seller-financing is that you are now the lender. That changes the risk you're holding in ways that have nothing to do with tax. The buyer's ability to keep paying is now your concern; the security for the note — what you can actually recover if they stop — matters enormously; and default, foreclosure, or renegotiation are real scenarios you need papered correctly from the start. None of that is do-it-yourself territory. The note structure, the security interest, and the default remedies are work for your real-estate attorney, and the tax treatment of every one of those scenarios is work for your tax professional.

What this means for you

An installment sale is a legitimate tool, and for the right seller it genuinely smooths the timing of a large gain. But go in with the whole picture: it spreads the gain eligible for installment reporting, not the depreciation recapture, and the recapture — especially the §1245 recapture a cost-seg operator carries — is generally recognized in the year of sale while most of the money is still outstanding. On top of that, the interest is ordinary income, and you've taken on a lender's risk. Whether to sell at all, and whether to sell versus exchange or refinance, is a separate decision (that's "Should I Sell, 1031, or Refinance?"). If you do sell on installments, the year-one recapture math and the note structure are the two things to nail down first — with your own tax professional and real-estate attorney, every time.

The bottom line

An installment sale under §453 does one real thing well: it lets you report the gain that's eligible for installment reporting as you actually receive the money, using a gross-profit percentage, instead of all at once. What it does not do is spread the depreciation recapture — under §453(i) the ordinary recapture income, most notably the §1245 recapture a cost-seg owner carries, is generally recognized in the year of sale regardless of when you're paid, which can create a real year-one tax liability. Add ordinary-income interest (stated or imputed under §483/§1274) and a lender's credit-and-default risk, and the honest summary is: the structure can help, but "spread the sale, spread the tax" is only half true. Model the year-one recapture number and paper the note with your tax professional and real-estate attorney before you commit.
