A 1031 exchange lets a real estate investor sell an investment property and roll the proceeds into a new one without paying capital gains tax in the year of the sale. The tax is not forgiven — it is deferred, carried forward into the replacement property's cost basis — but deferral compounds. An investor who keeps exchanging properties over decades can defer gains indefinitely, and the basis question can reset entirely if the property passes to heirs. Here is how the mechanics actually work and how to weigh it against just selling and paying the tax.
What changed in 2026
- 1031 exchanges remain limited to real property. The 2017 tax law removed personal property (equipment, vehicles, art) from eligibility, and that has not changed.
- Delaware Statutory Trusts (DSTs) grew as a replacement option for investors who want to exchange out of active management into a passive, professionally managed interest.
- Qualified intermediary requirements stayed strict — proceeds must pass through a QI and never touch the seller's hands or accounts.
- State-level conformity varies more than people expect — a handful of states do not fully honor federal 1031 deferral for state tax purposes, so check the rules where the property sits.
How the deferral actually works
Sell an investment property, and normally you owe capital gains tax (plus depreciation recapture) on the gain in that tax year. A 1031 exchange defers all of it by treating the transaction as a continuation of the same investment rather than a sale and a separate purchase — provided you follow the rules exactly:
- Use a qualified intermediary (QI). The QI holds the sale proceeds. You never receive the cash directly — doing so disqualifies the exchange immediately.
- Identify replacement property within 45 days of closing the sale. You can identify up to three properties regardless of value, or more under specific value-based rules.
- Close on the replacement within 180 days of the original sale (not 180 days from identification).
- Match or exceed value and debt. To defer 100% of the gain, the replacement property must be equal or greater in value, and equal or greater in debt, or the gap must be covered with additional cash.

1031 exchange vs the alternatives
- Sell and pay the tax. Simple, no deadlines, no replacement property required — but you lose the deferred amount to tax immediately, which is real capital that stops compounding.
- Opportunity zone fund. Defers gains from any asset (not just real estate) if reinvested within 180 days, with different holding-period benefits — a broader but differently structured deferral tool.
- Installment sale. Spreads the gain, and the tax, over the years you receive payments, rather than deferring it entirely — useful when you are financing the buyer directly.
- Hold until death. Heirs can receive a stepped-up basis, which can eliminate the deferred gain entirely rather than just postponing it — the reason many long-term investors chain exchanges until they stop investing.
Common mistakes
Missing the 45-day identification window. It is calendar days, not business days, and it does not extend for weekends or holidays. Line up a qualified intermediary and a shortlist of replacement properties before you close the sale.
Touching the sale proceeds. Even briefly. The funds must go from title company to qualified intermediary to the new purchase — any detour through the seller's own account disqualifies the exchange.
Under-buying on value or debt. Buying a replacement property for less than the sale price, or with less debt than the original without adding cash to cover the gap, creates "boot" — the difference becomes taxable.
Assuming every state honors it the same way. A few states claw back deferred gain if you eventually sell a replacement property located outside that state. Check before assuming full conformity.
FAQ
Does a 1031 exchange eliminate capital gains tax?
No, it defers it. The gain rolls into the replacement property's lower cost basis, so the deferred tax is generally owed eventually unless the property is held until death or exchanged again.
Can I exchange a rental property for a Delaware Statutory Trust?
Yes. DSTs are a common way to exchange out of hands-on property management into a passive, professionally managed fractional interest while still qualifying as like-kind real property.
What happens if I cannot find a replacement property in time?
The exchange fails, and the sale is treated as a normal taxable sale in that year. This is why lining up a qualified intermediary and candidate properties before closing matters so much.
Is a 1031 exchange worth it for a small gain?
Not always. The intermediary fees and the constraint of finding a qualifying replacement property within tight deadlines can outweigh the benefit for a modest gain — run the numbers against simply paying the tax.
