What Happens to Your 1031 Exchange If You Die? Step-Up in Basis, DST Inheritance, and the Estate Planning Strategy Retirees Use

There’s a question that comes up almost every time a retiring real estate investor sits down to think seriously about their estate. They’ve done a 1031 exchange — or they’re considering one — and they want to know: What happens to all those deferred taxes if I die before I sell?

It’s a fair question. It’s also a crucial one. Because the answer changes the entire calculus of the 1031 exchange strategy. For many investors, it transforms a good tax deferral tool into one of the most powerful wealth-transfer mechanisms available in the U.S. tax code.

The short answer: when you die holding a 1031 exchange investment, your heirs may receive what’s called a step-up in basis — and that step-up can permanently eliminate every dollar of capital gains tax you deferred during your lifetime.

Read that again, because it matters. The taxes you deferred with each 1031 exchange don’t just stay deferred. They may disappear entirely at your death.

This article explains exactly how that works, what it means for Delaware Statutory Trust (DST) investors specifically, and how sophisticated retirees are using this strategy — known informally as “die and defer” — as a cornerstone of their estate planning.

Understanding Basis: The Foundation of Everything

Before we can discuss what happens at death, we need to understand what “basis” means in the context of real estate investing.

Your tax basis in a property is essentially what the IRS considers you to have “paid” for it — for tax purposes. When you sell a property, the taxable gain is calculated as the sale price minus your basis. A higher basis means a smaller taxable gain. A lower basis means a larger taxable gain.

When you originally purchased a rental property, your basis was generally your purchase price (plus certain closing costs). But two things happen over time that change your basis:

1. Depreciation reduces your basis. Every year you own a rental property, you take depreciation deductions — typically over a 27.5-year schedule for residential real estate. Each deduction reduces your adjusted cost basis. A property you bought for $300,000 and depreciated for 15 years might have an adjusted basis of only $150,000 or less — even though its market value has climbed to $700,000 or more.

2. A 1031 exchange carries your basis forward. When you do a 1031 exchange, you don’t start fresh. Your basis in the new replacement property is “carried over” from the old property — minus the deferred gain. In effect, all those years of appreciation and depreciation follow you into the new investment. The IRS is deferring the tax, not erasing it — the gain sits inside the replacement property like a ticking clock.

This is why many investors worry about what happens to that deferred, accumulated gain when they die.

The Step-Up in Basis at Death: How It Works

Here’s where the tax code does something remarkable.

Under current U.S. tax law (IRC Section 1014), when an asset is included in a deceased person’s taxable estate, the heir receives a new basis equal to the fair market value of the asset on the date of death. This is the “step-up in basis.”

In practical terms: if you die holding a DST investment with a fair market value of $1,200,000 and your original carried-over basis was $150,000, your heirs’ new basis becomes $1,200,000. The $1,050,000 gain that had been accumulating — much of it deferred through years of 1031 exchanges — simply vanishes. No income tax on it. Ever.

Your heirs can then sell the investment and owe capital gains tax only on appreciation that occurs after your death.

Scenario	Basis	Market Value	Taxable Gain
You sell during lifetime	$150,000 (carried-over)	$1,200,000	$1,050,000
Heir sells after inheriting (stepped-up)	$1,200,000	$1,200,000	$0

The difference in tax outcome is extraordinary. And it’s entirely legal — it’s been in the tax code for decades.

The “Die and Defer” Strategy: Intentional, Not Accidental

The step-up in basis isn’t a loophole or an accident. It’s a feature of the tax code that sophisticated investors plan around deliberately.

The “die and defer” strategy works like this:

1. Sell your investment property using a 1031 exchange to defer capital gains taxes
2. Exchange into a passive replacement property — such as a DST — that provides income without management burden
3. Continue exchanging (if needed) throughout your lifetime, each time deferring taxes further and letting your wealth compound on a pre-tax basis
4. Hold until death — at which point your heirs receive a stepped-up basis, permanently eliminating the deferred gain

The result: you enjoy passive income from your DST investments throughout retirement, your wealth grows without being eroded by capital gains taxes during your lifetime, and your heirs inherit the wealth without the tax liability you accumulated.

This strategy works because of the interaction between three provisions of the tax code:

• IRC Section 1031 — defers capital gains on like-kind exchanges
• IRC Section 1014 — steps up basis to fair market value at death
• IRC Section 167/168 — allows ongoing depreciation deductions on replacement property (DSTs pass through depreciation to beneficial owners)

Together, these provisions create a powerful and entirely legal wealth-preservation engine.

What Happens to a DST When the Investor Dies?

Now let’s get specific about Delaware Statutory Trusts, because DSTs have unique structural features that affect how they’re handled in estate planning.

Your DST Interest Is Personal Property

When you invest in a DST, you hold a beneficial interest in the trust — not direct title to real property. This beneficial interest is personal property, similar in estate treatment to stock or a limited partnership interest. It can be:

• Held in a revocable living trust
• Transferred to heirs through a will
• Titled in a way that allows it to pass outside of probate

This is actually an advantage compared to directly-owned real estate. A building in three states creates probate complexity in three jurisdictions. A DST beneficial interest is a single asset that flows through your estate plan like any financial investment.

DST Income Continues After Death

One important practical point: DST distributions don’t stop when you die. The trust continues to hold its property, the tenants continue to pay rent, and income distributions continue to flow — they simply flow to your estate or trust until the interest is properly transferred to your heirs.

This means there’s no income interruption during the estate administration process, which can be a significant comfort to surviving spouses or family members depending on that income.

Heirs Receive the Stepped-Up Basis

When your DST beneficial interest passes to your heirs, they receive the stepped-up basis as described above. They then have several options:

Option 1: Continue holding the DST. They can hold the beneficial interest and continue receiving income distributions. Their stepped-up basis means that when the DST eventually sells the underlying property, their taxable gain will be calculated from the stepped-up amount — not from your original carried-over basis.

Option 2: Sell the interest. Because basis has been stepped up, your heirs can sell the DST beneficial interest (if the secondary market allows) with little or no capital gains exposure, assuming they sell close to the date-of-death value.

Option 3: Execute their own 1031 exchange. Your heirs can take their stepped-up interest into a new 1031 exchange when the DST is liquidated, deferring any appreciation that has occurred since your death. The cycle continues — now with a clean, stepped-up starting point.

How DSTs Work With Revocable Living Trusts

Most estate planning attorneys recommend that real estate investors — and DST investors in particular — hold their assets inside a revocable living trust (also called a grantor trust or family trust). Here’s why this matters enormously for DST investors.

The Probate Advantage

Without a living trust, assets typically must pass through probate — a public, court-supervised process that can take months or years and may involve significant legal fees. For a DST investor, probate in multiple states is generally not an issue (since the DST interest is personal property), but probate can still delay the transfer of your investment to your heirs.

A revocable living trust allows your DST interest to transfer to your beneficiaries immediately, without court involvement.

The Tax Treatment Is Preserved

From the IRS’s perspective, assets held in a revocable grantor trust are treated as if they’re owned directly by the grantor (you). This means:

• Your 1031 exchange can be completed using a revocable trust
• The DST beneficial interest held in a revocable trust still qualifies for the step-up in basis at death
• Your estate tax exposure is not affected by the trust structure

This is a critical point: a properly structured revocable living trust does not compromise the 1031 exchange treatment or the step-up in basis. Your estate attorney and tax advisor should confirm the trust is properly drafted, but this is standard practice for DST investors.

Naming Your Trust as the DST Investor

When you invest in a DST through a 1031 exchange, you can often take title to the beneficial interest in the name of your revocable living trust (e.g., “The Smith Family Trust dated January 15, 2020”). This allows the interest to flow directly to your named beneficiaries upon your death without probate — exactly as designed.

Work with your DST sponsor and the Qualified Intermediary (QI) during the exchange process to ensure the titling is done correctly. Each sponsor has slightly different procedures, but this is a well-understood and routine practice in the DST industry.

Spousal Considerations: Community Property and Portability

If you’re married, there are additional layers of planning that interact with your DST and 1031 exchange strategy.

Community Property States

In community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), assets acquired during marriage are typically considered jointly owned. When one spouse dies, the surviving spouse may receive a full step-up in basis on community property assets — not just the decedent’s half.

This is an even more favorable treatment than in common law states, where only the decedent’s 50% share typically receives the step-up. For a married couple in a community property state holding a DST in a revocable trust, the surviving spouse may receive a complete basis reset at the first spouse’s death — again, eliminating the entire deferred gain.

Estate Tax Portability

The federal estate tax exemption is currently very high (over $13 million per individual in 2024, with a married couple able to shelter more than $27 million). Most retirees holding DSTs will not face estate tax on the DST assets themselves — though the overall estate size matters. A qualified estate planning attorney can advise on portability elections and how your DST holdings factor into your overall estate tax picture.

Risks and Considerations: What Can Go Wrong

The “die and defer” strategy is powerful, but it requires careful planning. Here are the risks to understand:

Estate Tax Law Changes

The step-up in basis provision (IRC Section 1014) has been subject to legislative debate. There have been proposals in Congress to modify or limit the step-up. As of today, the provision remains in full effect — but investors should be aware that future tax law changes could alter this strategy’s outcome. Diversification and flexibility in your planning are prudent.

Improper Exchange Documentation

The tax benefits only apply if your 1031 exchanges were properly executed. An exchange that failed to meet the 45-day identification deadline, the 180-day closing deadline, or the Qualified Intermediary requirement could mean the gains were already taxable — and there’s no step-up to rescue an improperly executed exchange.

Choosing the Wrong DST Sponsor

Not all DST investments are created equal. A DST that underperforms, defaults on its debt, or is managed by a sponsor with poor track record doesn’t just produce bad income — it produces a stepped-up basis at a lower value than expected, while your family endures years of stress. The quality of your DST sponsor matters enormously, both for income during your lifetime and for the asset your heirs inherit.

Trust Drafting Errors

A revocable living trust that is improperly drafted can create complications. If the trust isn’t properly structured for 1031 exchange participation, it could jeopardize your exchange. Make sure your estate planning attorney is familiar with 1031 exchanges and DST investments specifically — not all general practitioners are.

A Worked Example: The Ramírez Family Strategy

Let’s make this concrete with a realistic scenario.

Starting point: Eduardo and Carmen Ramírez, both 68, own a four-unit apartment building in Phoenix they purchased in 1998 for $280,000. Today it’s worth $1,100,000. Their adjusted basis (after depreciation) is $140,000. The potential tax bill on a straight sale: approximately $280,000.

Step 1 — 1031 exchange into a DST: Instead of selling outright, Eduardo and Carmen execute a 1031 exchange, moving their equity into a diversified DST portfolio through their revocable family trust. They defer the full $280,000 in potential taxes. Their carried-over basis in the DST is $140,000.

Step 2 — 15 years of passive income: From ages 68 to 83, the Ramírez family receives monthly distributions from the DST — roughly $4,000–$5,500 per month based on a 5.5% distribution rate on $1.1 million. They never fix a toilet. They never screen a tenant. They travel, they spend time with grandchildren, they live their retirement.

Step 3 — Eduardo dies at 83: The DST beneficial interest, held in the family trust, is valued at $1,250,000 at the time of his death (the properties appreciated modestly). Carmen, as surviving spouse and co-trustee, receives a full basis step-up to $1,250,000 — eliminating the $1,110,000 in accumulated (depreciated + appreciated) gain.

Step 4 — Carmen’s options: Carmen can continue holding the DST and receiving income. When the DST eventually sells its properties, any gain above $1,250,000 will be taxable — but the decades of deferred gain Eduardo accumulated are gone entirely. If Carmen later does her own 1031 exchange with her share of the proceeds at DST liquidation, she too can defer further — with a clean starting basis.

Total capital gains taxes paid on $1,100,000 of real estate wealth: $0 on all gains accumulated during Eduardo’s lifetime.

The Right Professionals for This Strategy

Implementing “die and defer” correctly requires a coordinated team:

Estate Planning Attorney — drafts your revocable living trust, ensures it’s structured for 1031 compatibility, advises on titling of DST interests, and handles the estate administration.

CPA or Tax Advisor — monitors your basis tracking across exchanges, advises on depreciation treatment, and plans for any estate tax exposure.

Financial Advisor (DST Specialist) — identifies suitable DST replacement properties, manages the exchange process with a QI, and ensures proper titling in the trust name.

Qualified Intermediary (QI) — holds your exchange funds and ensures compliance with the IRS’s procedural requirements.

This is not a DIY strategy. The savings potential is enormous — potentially hundreds of thousands of dollars in taxes permanently eliminated — but the execution must be precise.

Frequently Asked Questions

Q: Do heirs have to do a 1031 exchange to avoid taxes when the DST sells?

No. If your heirs inherit a DST interest with a stepped-up basis and the DST subsequently sells the underlying property at or near the stepped-up value, the taxable gain is minimal or zero. They don’t need to exchange — they can simply receive the proceeds. However, if the DST appreciates significantly after your death, a new 1031 exchange by your heirs could defer that post-death appreciation.

Q: What if I’m in a 1031 exchange when I die — the exchange isn’t complete yet?

An incomplete exchange — where you’ve sold the relinquished property but haven’t yet closed on the replacement — creates complications. Your estate would need to complete or abandon the exchange. This is an edge case, but it highlights why some investors prefer to complete an exchange well before anticipated health declines.

Q: Can a DST beneficial interest be held in an irrevocable trust?

Yes, but the tax treatment changes significantly. Assets in an irrevocable trust generally do not receive a step-up in basis at the grantor’s death (since they’re no longer part of the taxable estate). Irrevocable trusts are typically used for estate tax reduction, not basis step-up purposes. Your estate planning attorney can advise on which structure fits your goals.

Q: What happens to the DST’s debt at my death?

DST debt is held at the trust level, not the investor level (it’s non-recourse to individual investors). Your heirs inherit the beneficial interest inclusive of its proportionate share of trust-level debt — but they have no personal liability for it. The debt is reflected in the asset’s value and doesn’t separately transfer to your estate.

Q: Does the step-up apply to IRAs or other tax-deferred accounts?

No. The step-up in basis applies only to assets held outside of tax-deferred accounts. DST interests held in an IRA or similar account do not receive a step-up — distributions are taxed as ordinary income regardless. DSTs are generally structured for non-retirement account investors who have a 1031 exchange event. This is an important distinction.

Your Next Steps

If you’re a retiring real estate investor considering a 1031 exchange, the estate planning dimension of this strategy deserves serious attention — not as a morbid exercise, but as a genuine wealth-maximization opportunity.

Here’s what to do now:

1. Understand DSTs thoroughly — the better you understand the investment vehicle, the better you can structure it within your estate plan. Start with our complete DST Beginner’s Guide →

2. Evaluate your DST sponsor options — since the quality of the underlying investment affects both your lifetime income and what you leave behind. See our vetted DST sponsor comparison →

3. Consult an estate planning attorney — specifically one who understands 1031 exchanges and DST investments. The trust drafting and titling details matter.

4. Talk to a DST specialist — to model what your specific portfolio would look like through a 1031 exchange and how it would interact with your estate plan.

The 1031 exchange and the step-up in basis have been part of the U.S. tax code for decades. For real estate investors willing to plan carefully, they represent one of the clearest examples of working with the tax code rather than against it — building wealth during your lifetime, passing it to your family intact, and letting compound growth do its work without the drag of taxes along the way.
