Yes, an irrevocable trust can do a 1031 exchange and defer capital gains tax when it swaps one investment property for another. The catch is that the trust’s federal tax classification, not its label in the trust document, decides who the IRS treats as the taxpayer for the exchange. Get the classification right and the mechanics look like any other 1031 exchange. Get it wrong and the deferral fails entirely.
Since the Tax Cuts and Jobs Act of 2017, Section 1031 applies only to real property. A trust hoping to exchange equipment, artwork, or other assets has no deferral available.1Internal Revenue Service. Like-Kind Exchanges – Real Estate Tax Tips
Grantor Trust or Non-Grantor Trust: Figure This Out First
Before the trustee lists the property, the trust needs to know which kind of taxpayer it is. The IRS draws a bright line between grantor and non-grantor trusts, and that line controls almost every downstream decision in the exchange.
Grantor Trusts
A grantor trust is one where the person who created it kept enough control that the IRS ignores the trust as a separate entity for income tax purposes. Under Sections 673 through 677 of the Internal Revenue Code, specific retained powers trigger this treatment: a reversionary interest in the trust assets, the power to control who benefits from the trust, certain administrative powers such as the ability to swap assets, the power to revoke the trust, or having trust income flow back to the grantor or the grantor’s spouse.2Office of the Law Revision Counsel. 26 U.S. Code 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners Any one of these is enough. The grantor reports all trust income and deductions on their personal return as if they still owned the assets directly.
For exchange purposes, that makes the grantor the taxpayer. The trust holds legal title, but the IRS sees through it. This is a common setup with irrevocable trusts used in estate planning, particularly Intentionally Defective Grantor Trusts (IDGTs), which are irrevocable for estate tax purposes but treated as the grantor’s alter ego for income tax.
Non-Grantor Trusts
When the grantor gave up enough control that none of the grantor trust triggers apply, the trust becomes its own taxpayer. It has its own Employer Identification Number, files its own Form 1041, and pays tax at trust rates on any undistributed income.3Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts For a 1031 exchange, the trust itself is the taxpayer and the beneficiaries are irrelevant to the mechanics.
The Same Taxpayer Rule
Classification matters because Section 1031 requires that the same taxpayer who disposes of the old property also acquire the replacement property.4Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment If a non-grantor trust sells a rental building, that same trust must take title to the replacement. Beneficiaries cannot buy the replacement in their own names, even if they are the ones who will eventually benefit. For a grantor trust, the grantor is the taxpayer, and title usually stays with the trust to preserve continuity.
Trouble arises with entities that change form mid-exchange. An LLC that converts to a trust between sale and purchase, or a trust that distributes the sale proceeds to beneficiaries who then buy replacement property individually, breaks continuity and triggers immediate gain recognition. Any trust considering an exchange should have its tax classification confirmed by a tax advisor before the relinquished property goes on the market.
The Standard 1031 Rules Still Apply
Once the taxpayer identity is settled, a trust’s exchange runs on the same rules as anyone else’s.
- 45-day identification window. The trust must identify potential replacement properties within 45 days of selling the relinquished property.
- 180-day completion deadline. The trust must close on the replacement property within 180 days of the sale, or by the due date (with extensions) of the tax return for the year of the sale, whichever is earlier. If the return comes due before day 180 and no extension is filed, the earlier date controls.4Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
Both properties have to be real property held for investment or business use. Property held primarily for sale, such as a flip project, does not qualify.4Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
The trust also needs a qualified intermediary to hold the sale proceeds and use them to acquire the replacement. If the funds hit the trust’s bank account, the exchange is dead. Treasury regulations disqualify anyone who has acted as the taxpayer’s employee, attorney, accountant, investment banker, broker, or real estate agent within the two years before the exchange. For trusts, this catches people off guard: the attorney who drafted the trust document or the CPA who prepares its Form 1041 cannot serve as the intermediary. Financial institutions, title companies, and escrow companies that provide routine services are excepted. Related parties are also disqualified, using a 10 percent ownership threshold instead of the usual 50 percent.5eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges
If the replacement property costs less than the relinquished property, the trust receives boot (leftover cash or debt relief), which is taxable up to the amount of boot received. The remaining gain stays deferred.6Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031 Debt relief counts as boot: a relinquished property with a $500,000 mortgage swapped for one with a $300,000 mortgage produces $200,000 of boot. When a trustee is struggling to find equal-value replacement property before day 45, accepting some boot can be better than losing the whole exchange.
Trust-Specific Traps
Related Party Rules Reach Broadly
If the trust plans to buy replacement property from a related party or sell to one, Section 1031(f) requires both sides to hold their respective properties for at least two years after the exchange. Disposing of the property within that window retroactively disallows the deferral.4Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment For trusts, the related-party universe is broad: beneficiaries, the grantor, entities controlled by the grantor or beneficiaries, and other trusts with overlapping parties can all qualify. Narrow exceptions exist for death, involuntary conversions such as condemnation, and transactions with no tax avoidance purpose. Under Revenue Ruling 2002-83, the IRS has also taken the position that acquiring replacement property from a related party who then pockets the cash can void the exchange even when the two-year holding requirement is technically met.
Holding the Replacement Property Long Enough
Section 1031 requires the replacement property to be held for investment or business use. If a trust acquires a replacement and promptly distributes it to a beneficiary, the IRS can argue the trust never intended to hold for investment and disqualify the exchange. There is no bright-line safe harbor in the statute. Some tax advisors recommend holding for at least 12 months so the property appears on two tax returns, which helps demonstrate investment intent. Revenue Procedure 2008-16 sets a 24-month safe harbor for vacation and mixed-use properties with specific rental and personal-use requirements, though it was written for individuals and its application to trusts is less clear.
Pre-planned distributions are the most dangerous version of this. If the trust agreement requires the trustee to hand the replacement property to a beneficiary at acquisition, the IRS will treat the exchange as a disguised cash-out. Involuntary terminations like a court-ordered dissolution may be treated differently, but those are fact-specific and rare.
What If the Grantor Dies Mid-Exchange?
For a grantor trust, the grantor’s death changes the trust’s tax classification immediately. A trust that was disregarded for income tax purposes becomes either a non-grantor trust or part of the decedent’s estate, depending on the trust’s terms. That shift in taxpayer identity during an open exchange raises real questions about whether the same-taxpayer rule is satisfied. The estate or successor trustee generally can complete the exchange, but only if the trust document or estate plan gives them that authority.
The decision is not automatic because of the potential step-up in basis under Section 1014. If the property receives a step-up to fair market value at death, there may be little or no gain left to defer, making the exchange unnecessary.
Not every grantor trust property gets a step-up. In Revenue Ruling 2023-2, the IRS took the position that assets in an irrevocable grantor trust do not receive a basis adjustment under Section 1014 when the grantor dies, if those assets are not included in the grantor’s taxable estate. The ruling specifically targets IDGTs. Under it, the trust assets keep their carryover basis, and any deferred gain from a completed 1031 exchange survives too. If the trust property would not get a step-up anyway, the case for completing the exchange is stronger. If the property would be included in the grantor’s estate and receive a full step-up, completing the exchange may waste time and money on a deferral that death would have made irrelevant. Older grantors should have their estate planning documents reviewed alongside any exchange strategy.
What the Trustee Needs to Check Before Starting
The trustee drives the process. Even when the taxpayer is technically the grantor or the trust itself, the trustee signs the purchase agreements, closing documents, and the exchange agreement with the qualified intermediary, and holds legal title to both properties.
Three things need to be confirmed before the relinquished property is listed:
- The trust document authorizes the trustee to engage in 1031 exchanges. Some trust instruments restrict the transactions a trustee can enter.
- The trust’s tax classification (grantor or non-grantor) has been verified in writing by a tax advisor.
- The qualified intermediary is not a disqualified person under the two-year lookback rule.5eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges
Legal review of the exchange documents by an attorney familiar with both trust law and 1031 requirements catches issues that would otherwise surface only during an audit.
Reporting the Exchange
Every 1031 exchange is reported on Form 8824 for the tax year the relinquished property was sold.7Internal Revenue Service. Instructions for Form 8824 For a non-grantor trust, Form 8824 is filed with the trust’s Form 1041. For a grantor trust, it is filed with the grantor’s individual return, since the trust is disregarded for income tax purposes. The form calculates deferred gain and the basis of the replacement property, and requires a description of both properties, dates of transfer and acquisition, and amounts of any boot received. Failing to file it does not automatically disqualify the exchange, but it invites scrutiny and makes the deferral harder to defend later.
