How to Avoid Capital Gains Tax on Real Estate: Eight Legal Methods and What Each Saves

The eight methods compared

Every method either removes the gain, defers it to a later year, or spreads it. None are available for every property, and several carry costs or risks. Use the table to see which fits your sale before reading the details.

Exclude the gain on your home

The only complete exclusion for a living owner is the main-home rule. Own it and live in it for 2 of the 5 years before sale and you exclude up to $250,000 of gain, or $500,000 filing jointly. Depreciation you claimed after May 6, 1997 is not excluded.

A rental that becomes your residence for the last two years can qualify in part. The full rules are on selling a house.

Defer with a 1031 exchange

For investment or business real estate, a like-kind exchange under IRC 1031 defers all the gain if you identify replacement property within 45 days and close within 180 days, using a qualified intermediary, and buy property of equal or greater value with all the proceeds.

Since 2018, only real property qualifies. The gain is not forgiven; your basis carries into the new property, and the deferred gain and depreciation recapture come due when you eventually sell for cash.

If you cannot find a replacement, an installment sale instead of a 1031 is the common alternative, and a failed exchange has its own consequences (failed 1031 exchange). Start with the 1031 exchange analysis.

Spread the gain with an installment sale

If you receive at least one payment after the year of sale, you can report the gain as payments come in (IRC 453). Each payment carries a gross-profit share of gain. In our Arizona example the rental produces a $750,000 gain.

Sold for cash in one year, the federal and state tax is $180,283. Sold on a five-year note with equal principal payments, tax is $152,378 in total, a difference of $27,905, because the long-term gain is spread across lower brackets and below the 3.8% NIIT threshold in some years.

Depreciation recapture is reported in year one regardless of when you are paid, so the $150,000 of unrecaptured 1250 gain is in the first year. Note interest is taxable. Run your own case in the installment sale analysis.

Hold until death for a stepped-up basis

Property included in a decedent's estate takes a basis equal to its fair market value at death (IRC 1014). An heir who inherits a building bought for $200,000 and worth $950,000 and sells it at $1,000,000 has a $40,000 gain, not an $800,000 one, and pays $7,980 of tax in Illinois on the example.

Heirs also receive long-term treatment automatically. This is the largest single tax-avoidance feature in the code for real estate, and the reason many owners never sell. The cost is that the property stays illiquid and concentrated. See step-up at death and inherited property.

Opportunity zones, charitable trusts and donation

A Qualified Opportunity Fund investment of capital gain within 180 days of the sale defers recognition of the invested gain, and the program was changed by 2025 legislation (see opportunity zones).

A charitable remainder trust sells the property inside the trust without immediate tax and pays you income for a term or life, spreading the gain over the payout (IRC 664). Donating the property outright to a qualified charity avoids the gain and produces a deduction.

Each commits the property or the proceeds to a structure you cannot reverse.

What none of these remove: depreciation and the 3.8% surtax

Depreciation taken on rental real estate is taxed on a sale at up to 25% in 2026 (unrecaptured section 1250 gain) unless you defer through a 1031 or hold until death. Investors with modified AGI above $250,000 joint or $200,000 single also owe the 3.8% net investment income tax on the gain (IRC 1411).

Check both on your own sale in the capital gains tax calculator, and see depreciation recapture for how the 25% layer is computed.
