A 1031 exchange and a step-up in basis at death are two of the most powerful tools for deferring or eliminating tax on appreciated real estate — and they are often used together. This guide compares them, explains when each shines, and how the classic "exchange until death" plan combines both.
General information only — not tax, legal, or financial advice. A 1031 exchange has strict, unforgiving deadlines and significant tax consequences. Work with a CPA and a qualified intermediary (QI) before you act. A REALTOR® cannot serve as your QI. Verify current IRS and California FTB rules with a licensed tax professional.
Two strategies, two purposes
- 1031 exchange: defers capital gain and depreciation recapture when you sell, by reinvesting in like-kind replacement property. The gain is postponed, not erased — until something else happens.
- Step-up in basis: at death, heirs generally take a basis equal to fair market value, which can wipe out the deferred (and prior) gain for income-tax purposes, subject to current law and estate tax.
How they work together
The classic plan is to exchange repeatedly during your lifetime — deferring gain each time — and then hold the final replacement property until death. Heirs inherit with a stepped-up basis, and the income tax on a lifetime of deferred gain can disappear. This is why 1031 is often framed as an estate-planning tool, not just a tax-deferral trick.

When to favor a 1031 exchange
- You are still actively investing and want to upgrade or reposition assets.
- You are not near the end of your investment horizon.
- You want to keep equity working rather than pay tax now.
- You are consolidating or diversifying your portfolio.
When the step-up is the bigger lever
- You are older or planning your estate and intend to pass property to heirs.
- You have substantial deferred gain that a step-up could eliminate.
- You want heirs to receive assets with minimal income-tax baggage.
- Your estate is below applicable estate-tax thresholds (verify current law).
The trade-offs
| 1031 exchange | Step-up at death | |
|---|---|---|
| Effect on gain | Deferred | Potentially eliminated for heirs |
| When it applies | During life, at each sale | At death |
| Liquidity | Keeps equity invested | No liquidity to you during life |
| Main risk | Deadlines, boot, recapture later | Estate-tax exposure; law changes |
Both strategies depend on current federal and California law, which can change. Verify the rules and your estate-tax exposure with your CPA and estate attorney before planning around them.

Frequently Asked Questions
Is a step-up in basis better than a 1031 exchange?
Neither is universally better — they serve different purposes. A 1031 defers gain during life; a step-up can eliminate it at death. Many investors combine both.
Can I use both strategies together?
Yes. The classic plan is to exchange repeatedly during life to defer gain, then hold the final property until death so heirs receive a stepped-up basis.
Does a 1031 exchange eliminate tax?
No, it defers tax. The gain is postponed and rolls into the replacement property's basis. Only a step-up at death (or other event) can eliminate it.
When should I favor holding for a step-up?
Generally when you are near the end of your investment horizon, intend to pass property to heirs, and have substantial deferred gain a step-up could erase.
Does estate tax affect this decision?
Yes. A large estate may face estate tax even with a step-up. Verify current thresholds and your exposure with your estate attorney and CPA.
Is this tax advice?
No. This is general educational information. Confirm strategy with your CPA and estate attorney.
