Can an Irrevocable Trust Do a 1031 Exchange?

An irrevocable trust can do a 1031 exchange and defer capital gains tax when it swaps one investment property for another, but the deferral only holds if the trust’s federal tax classification is pinned down first. That classification decides who the IRS treats as the taxpayer, and the taxpayer who sells the old property must be the same taxpayer who buys the new one. Get the classification wrong and the exchange collapses, no matter how clean the rest of the paperwork looks.

Grantor Trust or Non-Grantor Trust

The first question is not about real estate at all. It is whether the trust is a grantor trust or a non-grantor trust for income tax purposes, because the two are treated very differently.

A grantor trust is one where the person who created it kept enough control that the IRS disregards the trust as a separate entity for income tax. Under Sections 673 through 677 of the Internal Revenue Code, specific retained powers trigger this treatment: a reversionary interest, the power to control who benefits, certain administrative powers like the ability to swap assets, the power to revoke, or having trust income flow back to the grantor or the grantor’s spouse.¹ Any one is enough. The grantor reports all trust income and deductions on their personal return.

For exchange purposes, the grantor is the taxpayer. The trust holds legal title, but the IRS sees through it. This comes up constantly with Intentionally Defective Grantor Trusts (IDGTs), which are irrevocable for estate tax purposes while remaining the grantor’s alter ego for income tax.

A non-grantor trust is the opposite. The grantor gave up enough control that none of the Sections 673-677 triggers apply. The trust has its own Employer Identification Number, files its own Form 1041, and pays tax at trust rates on undistributed income.² For a 1031 exchange, the trust itself is the taxpayer. The grantor and beneficiaries are irrelevant to the exchange mechanics.

This is where most trust exchanges go wrong. A trust that assumes it is the taxpayer when the IRS actually treats the grantor as the taxpayer has mismatched the seller and the buyer. The mismatch kills the deferral. Any trustee considering an exchange should have the classification confirmed by a tax advisor before the property is listed.

The Same Taxpayer Rule

Classification matters because Section 1031 requires the taxpayer who disposed of the relinquished property to acquire the replacement property.³ The IRS enforces this strictly. If a non-grantor trust sells a rental building, the same trust must take title to the replacement. Beneficiaries cannot buy the replacement in their own names, even if they will eventually benefit from it.

The logic runs in reverse for grantor trusts. If a grantor trust sells, the grantor is the taxpayer, and the replacement needs to be acquired in a way consistent with that identity. In practice, the trust usually takes title to the replacement property just as it held the relinquished one, preserving the continuity the IRS requires.

Problems arise when the entity changes form mid-exchange. An LLC that converts to a trust between the sale and the purchase, or a trust that distributes the sale proceeds to beneficiaries who then buy property individually, breaks continuity and triggers immediate gain recognition.

Deadlines and the Real Property Limit

Once classification is settled, the mechanical rules for a trust are the same as for any other taxpayer. Two deadlines run from the day the relinquished property is sold:

45 days to identify potential replacement properties in writing.
180 days to close on the replacement, or by the due date (with extensions) of the tax return for the year of sale, whichever comes first.³

Neither deadline can be extended for good reasons or bad. A trustee still negotiating on day 46 has lost the exchange. The second rule catches people too: if the trust’s return is due before the 180th day, the earlier date controls unless the trust files an extension.

Since the Tax Cuts and Jobs Act of 2017, Section 1031 applies only to real property. A trust cannot use an exchange to defer gain on equipment, artwork, collectibles, or other intangibles.⁴ Both sides of the exchange must be real property held for investment or business use. Property held primarily for sale, like a flip, does not qualify.³

The Qualified Intermediary Trap

Almost every 1031 exchange runs through a qualified intermediary, a third party who holds the sale proceeds and uses them to acquire the replacement property. The taxpayer cannot touch the money in between. If funds hit the trust’s bank account, the exchange is dead.

The 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.⁵ For trusts this is a practical concern. The attorney who drafted the trust document and the CPA who signs the trust’s Form 1041 cannot serve as the intermediary. Trustees often assume the advisor who already knows the trust is the natural choice, and that assumption breaks the exchange.

There is an exception for financial institutions, title companies, and escrow companies providing routine services. The regulations also disqualify anyone related to the taxpayer under a modified related-party test, using a 10 percent ownership threshold instead of the usual 50 percent.⁵

Partial Exchanges and Boot

Nothing requires a perfectly equal swap. If the replacement property costs less than the relinquished property, or carries less debt, the trust ends up with leftover cash or debt relief. The IRS calls this boot, and it triggers taxable gain up to the amount of boot received.⁶ The rest of the gain stays deferred.

Trustees run into this often, because finding a replacement of equal or greater value inside 45 days can be hard. Taking a partial exchange and paying tax on the boot usually beats missing the deadline and losing the whole deferral. Debt relief counts as boot too. A $500,000 mortgage on the old property replaced by a $300,000 mortgage on the new one produces $200,000 of boot.

Holding the Replacement Before Distributing It

Section 1031 requires both the relinquished and replacement properties 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 it for investment and disqualify the exchange.

There is no bright-line safe harbor in the statute for how long a trust must hold the replacement before distributing. Some tax advisors recommend at least 12 months so the property appears on two tax returns, which helps demonstrate investment intent. For vacation or mixed-use properties, Revenue Procedure 2008-16 provides a 24-month safe harbor with specific rental and personal use requirements, though it was written for individual taxpayers and its application to trusts is less clear.

Pre-planned distributions are especially risky. If the trust agreement obligates the trustee to hand the replacement to a beneficiary on acquisition, the IRS will treat the exchange as a disguised cash-out rather than a continuation of the investment. The safest course is to hold and actively manage the replacement for a meaningful period before considering any distribution.

If the Grantor Dies Mid-Exchange

For grantor trusts, the grantor’s death during an open exchange creates immediate complications. The trust’s tax classification can shift the moment the grantor dies: a disregarded grantor trust becomes either a non-grantor trust or part of the decedent’s estate, depending on the trust’s terms. That shift in the taxpayer’s identity raises real questions about whether the same taxpayer rule is still satisfied.

The estate or successor trustee generally can complete the exchange, but the decision needs weighing against the 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, and completing the exchange is wasted effort. The personal representative or successor trustee needs explicit authority in the trust document to make the call.

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 Section 1014 basis adjustment 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’s property keeps its carryover basis after the grantor’s death, which means the deferred gain from a prior 1031 exchange survives as well. For older grantors, the exchange decision and the estate plan should be reviewed together.

Delaware Statutory Trusts as a Replacement Option

Trustees who cannot locate suitable replacement property inside 45 days should know about Delaware Statutory Trusts. In Revenue Ruling 2004-86, the IRS held that an interest in a properly structured DST qualifies as like-kind real property for Section 1031 purposes.⁷ A DST is a passive investment where a professional sponsor acquires and manages real estate, and investors hold beneficial interests.

For irrevocable trusts, DSTs can solve two problems at once: finding investment-quality replacement property on a tight deadline, and moving the trust out of active property management into something passive. The trade-off is strict structural limits. The DST cannot accept additional capital contributions after closing, cannot refinance existing debt, and cannot renegotiate leases except in narrow circumstances. The trustee has no management control over the underlying property, and the trust is locked into an illiquid investment for the life of the DST.

What the Trustee Should Confirm Before Starting

The trustee drives the whole process. Whether the taxpayer is the grantor or the trust itself, the trustee signs the purchase agreements, the closing documents, and the exchange agreement with the qualified intermediary, and holds legal title to both properties.

Three things should be nailed down before the relinquished property is listed:

The trust document actually authorizes the trustee to engage in 1031 exchanges. Some instruments restrict the trustee’s transaction powers.
The trust’s tax classification (grantor or non-grantor) has been confirmed by a tax advisor, in writing.
The intended qualified intermediary is not a disqualified person. The attorney who drafted the trust and the CPA who has prepared its returns within the past two years both fail this test.⁵

Legal review by an attorney familiar with both trust law and 1031 requirements usually catches issues that would otherwise only surface in an audit.
