Not everyone selling a property wants to buy another one.
Sometimes the honest position is that you are done. You do not want a replacement building, you do not want a DST, and you do not want to spend forty-five days under a clock choosing something you will regret. You just want the sale, and you would prefer the tax not arrive all in one year.
There is a mechanism for that, it has nothing to do with Section 1031, and it carries one trap that catches people badly enough to be worth the whole article.
What an installment sale actually does
Under Section 453, if you receive at least one payment after the year of sale, you generally report the gain as the payments come in rather than all at once.
Each payment is split three ways: a return of your basis, a slice of gain, and interest. The gain slice is set by a gross profit ratio fixed at the outset, so a fixed percentage of every principal payment is taxable gain.
Be clear about what this is and is not. A 1031 exchange defers the gain indefinitely and can eliminate it entirely at death through the step-up. An installment sale does not defer the gain, it spreads it. You will pay. The question is over how many years, and in which brackets.
Why spreading can still beat paying at once
- Bracket management. A $900,000 gain recognized in one year pushes you into the top rate and probably the net investment income tax. Spread over eight years it may sit in lower brackets throughout.
- You collect interest. The buyer is paying you interest on the unpaid balance, and that yield may exceed what you would have earned on the after-tax lump sum.
- You are actually out. No replacement property, no 45-day clock, no qualified intermediary, no exchange to fail.
And the honest costs on the other side:
- You are the bank. If the buyer defaults, you are foreclosing on a property you thought you had sold.
- Rates are not frozen. You are betting on future tax law across the whole term.
- No step-up on the gain. Unlike a chain of exchanges, the deferred gain in an installment note does not disappear at death; the remaining obligation is generally income in respect of a decedent.
The trap: recapture does not get to wait
Here is the part that ruins people's cash flow, and it is not intuitive.
Section 453(i) says that recapture income is recognized in full in the year of the sale, regardless of how little cash you actually received. Only the gain in excess of recapture gets the installment treatment.
The distinction that matters:
- Section 1245 recapture, personal property, fixtures, equipment, and anything a cost segregation study carved out of the building into 5, 7, or 15-year lives. This is ordinary income, due in year one, in full.
- Unrecaptured Section 1250 gain, the straight-line depreciation on the building itself, taxed at up to 25%. This is capital gain rather than ordinary recapture income, so it is generally not caught by 453(i) and can be spread, though it is typically recognized before the lower-taxed layers.
If you have run a cost segregation study, read that first bullet twice. Cost segregation front-loads deductions by reclassifying part of the building into shorter-lived Section 1245 property. That is excellent while you hold. On an installment sale, it creates exactly the category that cannot be spread.
What that looks like in cash
A small industrial property sells for $1.4 million against a $500,000 basis. A cost segregation study years ago reclassified $300,000 into 5 and 7-year property, since fully depreciated. Terms are 20% down with the balance over eight years.
| Amount | |
|---|---|
| Cash received at closing (20%) | $280,000 |
| Section 1245 recapture, due in year one | $300,000 |
| Tax on that recapture at 32% ordinary | About $96,000 |
| Remaining gain spread over eight years | $600,000 |
| Cash left from the down payment after that tax | About $184,000 |
Illustrative only, ignoring state tax, the capital gain portion also due in year one on the down payment, and your other income. Your CPA determines the real figures.
A third of the money you actually received in year one goes straight to tax on a gain you have mostly not collected yet. That is the phantom income problem, and the fix is not clever structuring. It is sizing the down payment so it covers the year-one bill before you sign.
How this sits next to a 1031
They are not rivals so much as answers to different questions.
| 1031 exchange | Installment sale | |
|---|---|---|
| The gain | Deferred, potentially forever | Spread, then paid |
| At death | Basis steps up, gain can vanish | Remaining obligation is generally taxable to your heirs |
| Do you buy again? | Yes, that is the point | No |
| Deadlines | 45 and 180 days | None |
| Who holds the risk | You own real estate | You hold the buyer's paper |
| Recapture | Deferred with everything else | Section 1245 portion due in year one |
They also combine. If you carry a note as part of an exchange, the note is boot, and the gain attributable to it can often be reported on the installment method as payments arrive. We covered the mechanics in seller financing inside an exchange.
One more interaction worth knowing: if an exchange fails and the money comes back to you in the following tax year, the timing can work in your favour. See what happens when an exchange fails.
Before you agree to carry paper
- Model year one first. Recapture, plus tax on the gain in the down payment, against the cash you will actually hold.
- Size the down payment to cover it. This single step prevents the phantom income problem.
- Underwrite your buyer the way a lender would, and secure the note properly against the property.
- Set adequate interest. Below-market rates get imputed, and you are taxed on interest you did not charge.
- Know you can elect out. You are permitted to report the entire gain in the year of sale if that suits your situation better, but the election has a deadline.

Common questions about installment sales
Is an installment sale a substitute for a 1031 exchange?
No. An exchange defers the gain and can eliminate it at death. An installment sale spreads the payment of a tax you will still owe.
Why is my recapture due immediately?
Section 453(i) requires recapture income to be recognized in the year of disposition regardless of payments received. Only gain above that amount is eligible for the spread.
Does depreciation on the building itself get caught by that rule?
Generally not. Straight-line depreciation on real property produces unrecaptured Section 1250 gain, which is capital gain rather than ordinary recapture income, so it can usually be spread.
Can I use both an installment sale and a 1031 exchange?
Yes, most commonly where you carry a note as part of an exchange. The note is boot, and gain attributable to it can often be reported on the installment method.
What happens if the buyer defaults?
You generally reacquire the property, with its own set of tax consequences, and you have already paid tax on gain recognized to date. Underwriting the buyer is not optional.
