Selling an asset for a large gain in one year can push you into higher brackets and across income thresholds. An installment sale — where the buyer pays over several years — spreads the gain across the years payments are received.
That can meaningfully reduce total tax by keeping each year's income lower. It also makes you the buyer's lender, which is a different business from selling something.
What changed in 2026
- Bracket and threshold management stayed the main driver. Spreading income to avoid crossing thresholds remained the principal benefit.
- Interest rate environment affected the note terms. Higher rates made seller financing more attractive to sellers and more expensive for buyers.
- Recapture treatment stayed unchanged. The exclusion of recapture from installment treatment continued to limit the benefit for depreciated property.
- Alternative deferral structures got more scrutiny. Arrangements marketed as achieving similar results attracted attention — see deferred sales trusts.
How the gain spreads
Each payment received consists of three components:
Return of basis — not taxable.
Gain — taxable in the year received.
Interest — taxable as ordinary income.
The gain portion of each payment is determined by the gross profit ratio: the total gain divided by the total contract price. That ratio applies to every principal payment, so gain is recognised proportionally as you are paid.
| Year |
Payment received |
Gain recognised |
| 1 |
Down payment |
Proportional share |
| 2–5 |
Annual instalments |

| Total |

Full gain, spread |
The benefit is entirely about rate. If spreading the gain keeps each year in a lower bracket, below a threshold triggering additional taxes, or below the level where deductions phase out, the total tax is lower than recognising everything at once.
Where your bracket would be the same either way, the benefit reduces to the time value of deferral, which is real but smaller.
Recapture does not spread
The limitation that most reduces the appeal for depreciated property.
Depreciation recapture is generally recognised in full in the year of sale, regardless of when payments arrive. Only the remaining gain spreads.
For a heavily depreciated rental property, recapture may be a large share of the total gain — which means a large tax bill in year one, on money you have not yet received.
That can produce a genuine cash flow problem: substantial tax due immediately against a small down payment. Sizing the down payment to cover the year-one tax is a practical necessity in those cases — see depreciation recapture.
You are the lender
The non-tax consideration that matters most.
An installment sale means you hold a note from the buyer. If they default, you have a legal process rather than money, and the asset may come back to you in worse condition than you sold it.
That risk should be priced and secured. A meaningful down payment, a security interest in the property, and genuine assessment of the buyer's ability to pay are all ordinary lending practice that sellers frequently skip because they are thinking about tax rather than credit.
Interest matters too. The note must charge adequate interest, or interest will be imputed — recharacterising part of the principal as interest, which is taxed as ordinary income rather than as gain. Charging a reasonable rate avoids that and is better for you anyway.
Common mistakes
- Assuming recapture spreads. It generally does not.
- A down payment too small to cover year-one tax. Cash flow problem immediately.
- Not securing the note. Unsecured seller financing is a poor position.
- Charging inadequate interest. Interest gets imputed at less favourable treatment.
- Not assessing the buyer's credit. Deferring tax on money you never receive.
- Overlooking the election requirement. Installment treatment may need to be affirmatively chosen or opted out of.
- Ignoring what happens if you sell the note. Disposing of it can accelerate the remaining gain.
FAQ
Can I choose not to use installment treatment?
Generally yes — you can elect out and recognise the whole gain in the year of sale, which may be preferable if you expect higher rates later or have losses to offset it now.
What if the buyer defaults?
You typically repossess, with its own tax consequences depending on what you have already recognised and what you recover. Messy, and a reason to secure the note properly.
Does this work for stock or business sales?
Installment treatment is available for many asset types with exceptions, notably for publicly traded securities and certain inventory. Business sales frequently involve components treated differently.
Can I sell the note later?
You can, and disposing of an installment obligation generally accelerates recognition of the remaining gain, which removes the deferral you structured for.
Where to go next
For the recapture that does not spread, read depreciation recapture. For the alternative deferral through reinvestment, like-kind exchange rules, and for structures marketed as alternatives, deferred sales trusts.
