A 1031 exchange defers a capital gain. It does not erase it — until the investor dies still holding the replacement property. At that point, under IRC Section 1014, basis resets to fair market value on the date of death, and the deferred gain and depreciation recapture that followed the investor through every prior exchange disappear for the heirs who inherit. That mechanism is what DST estate planning is built around, and a trust's capital structure and ownership form shape what heirs actually receive when the reset happens.
Two pieces of IRS guidance frame everything that follows. Revenue Ruling 2004-86 treats a beneficial interest in a properly structured Delaware Statutory Trust as a direct interest in real property for Section 1031 purposes, which is why a DST can serve as replacement property at all. Revenue Procedure 2002-22 addresses the older tenant-in-common route; among the conditions it lists for a favorable IRS ruling is a limit of 35 co-owners per property. It is guidance for ruling requests, not a statute.
Why DST estate planning works the way it does
"Swap till you drop" is the shorthand estate planners use. An investor defers gain through successive exchanges, and when direct ownership becomes too much to manage, a DST beneficial interest lets that deferral continue without landlord duties. The structural details behind the deferral carry more weight once the plan is to hold for life rather than simply to defer. The Top1031 directory tracks active offerings and the sponsors behind them, and the Learn library covers the underlying mechanics — identification windows, debt replacement, boot.
The step-up itself is indifferent to what happened inside the trust while the investor was alive. It applies to the fair market value of the real property interest on the date of death, whatever distributions were received or debt carried along the way. In community property states, both halves of a jointly held interest generally receive the adjustment rather than only the decedent's half. What changes with structure is everything upstream of that date: how much a disposition before death complicates the math, whether the interest divides cleanly among several heirs, and whether a mid-hold event such as a 721 UPREIT conversion changes the kind of asset being inherited.
The situation this describes
The reader here is an accredited investor who has sold, or is about to sell, an appreciated investment property and is working inside the 45-day identification window and the 180-day closing deadline. The 1031 mechanics are already familiar. The open question is narrower: if the replacement property is a DST the investor intends to hold for the rest of their life, which structural features shape the eventual transfer to heirs, and which are irrelevant to it.
One piece of context that shapes access: DST interests are securities, typically offered under Rule 506(b) or 506(c) of Regulation D. Those offerings are exempt from registration rather than registered. Under 506(c), every purchaser must be verified as accredited; 506(b) permits up to 35 non-accredited but sophisticated investors and bars general solicitation.
Structural features that bear on the estate outcome
Whether the trust is debt-free or leveraged
Debt does not block the step-up at death. It changes what happens if the position ends before death. When a leveraged trust sells, the investor either recognizes the deferred gain or completes another 1031 exchange — and in that exchange, the debt relieved at the DST level has to be replaced with new debt or additional cash, or it is treated as boot and taxed. An all-cash trust removes that variable for as long as the investor holds it. Top1031 tags this categorically — allcash, leveraged, zerocoupon, or unknown — rather than as a numeric ratio, because the category is what the filings support consistently.
Whether distributions are current or absent
A distributing DST pays income along the hold at whatever rate the offering documents describe. A zero-coupon structure is different in kind: these trusts are typically highly leveraged, with rent from a long-term, credit-tenant lease going to debt service instead of to investors, so equity builds through principal paydown rather than through cash distributions. That structure carries its own wrinkle during the hold — as interest expense falls, taxable income can rise without cash arriving to cover the tax on it. Either path reaches the same Section 1014 reset at death.
Minimum investment size and how the interest divides
A beneficial interest can generally be split among heirs down to the minimum the sponsor set at the original raise, subject to the trust agreement and to estate documentation. Tenant-in-common co-ownership sits under the 35-co-owner condition of Rev. Proc. 2002-22, which is the constraint that matters when a plan involves dividing one property's interest among several children rather than one.
Sponsor track record, and what a Sponsor Grade does not cover
A Top1031 Sponsor Grade is sponsor-level — A, B, C, D, F, or NR — built from a sponsor's tracked record and disclosure completeness. It is not a rating of any individual offering, not a forecast, not a tax opinion, and not a suitability judgment. It says nothing about how a specific trust's structure interacts with basis or step-up treatment.
Hold period versus life expectancy
Offering documents describe a hold period set by the sponsor's business plan, not by an investor's life expectancy. The two horizons rarely match, which is why the questions that follow tend to be about what happens if the sponsor disposes of the property, converts it through a 721 UPREIT, or otherwise ends the hold first.
How the structures compare
All-cash offerings carry no loan, so nothing has to be replaced if the trust is sold before death and no maturity date forces a decision inside the hold. The structure removes a variable rather than adding one.
Leveraged offerings put debt into the picture. Leverage lets a given amount of equity satisfy a larger replacement-value and debt-replacement requirement, and it introduces the possibility of taxable debt relief if the position unwinds before death. That is a characteristic of the structure, not a defect in it.
Zero-coupon offerings sit at the high-leverage end and pay no current distributions. For an investor who does not need income, the deferral does not change the step-up at death, since Section 1014 applies to fair market value however the return was delivered. The leverage, though, still means debt to replace in any pre-death exchange, and phantom income to plan for during the hold.
DST versus TIC is the divisibility question rather than a basis question. Step-up treatment is the same for both; the DST interest generally divides among multiple heirs without the retitling or partition problems that come with a co-ownership position capped near 35 investors.
Comparing the structures side by side
Feature | All-cash DST | Leveraged DST | Zero-coupon DST |
|---|---|---|---|
Basis at death | Section 1014 reset to full FMV | Same reset applies | Same reset applies |
If the trust sells before death | Gain recognized or exchanged forward; no debt to replace | Relieved debt must be replaced in a forward exchange or is treated as boot | Same as leveraged, at a higher debt level |
Cash flow during the hold | Distributions at the rate stated by the sponsor | Distributions net of debt service, as reported by the sponsor | None; rent services the loan |
Tax friction during the hold | Lowest | Loan maturity inside the hold period | Taxable income can exceed cash received |
What the structure changes for an estate plan | Fewer moving parts before death | A debt-replacement calculation if the hold ends early | A debt-replacement calculation plus annual tax without cash |
Common misreadings
- Reading a Sponsor Grade as a tax signal. A Grade evaluates a sponsor, not a trust's basis mechanics or estate outcomes, and it does not stand in for a CPA's review of a specific offering.
- Treating a 721 UPREIT conversion as a non-event. Converting a beneficial interest into operating partnership units replaces real property with a partnership interest. The units are generally eligible for a step-up at death, but the one-way nature of the conversion changes the options available afterward — an inherited OP unit position cannot be 1031-exchanged the way an inherited DST interest can.
- Assuming a leveraged trust can simply refinance its way out of a maturity. Revenue Ruling 2004-86 bars the trustee from renegotiating existing debt or borrowing new funds, with a narrow exception where a loan default is imminent because of tenant bankruptcy or insolvency. Working around that generally means converting the trust to an LLC — the "springing LLC" — which changes the tax character of the interest and forecloses a further 1031 exchange. The filings, not the original marketing material, show how a given trust's debt is structured and when it matures.
Questions that come up
Does a DST interest get the same step-up as directly owned real estate?
Yes. Because Revenue Ruling 2004-86 treats the beneficial interest as an interest in real property for 1031 purposes, and because the interest is included in the gross estate at fair market value, Section 1014 resets basis on the date of death as it would for a deeded property.
What do heirs actually hold the day after?
Beneficial interests in the trust, at stepped-up basis, with the same passive posture the decedent had. When the sponsor later sells the property, the heirs face little or no deferred gain from the decedent's exchange history and can take cash or exchange forward.
Does the step-up have anything to do with estate tax?
No. Section 1014 is an income tax basis rule. The interest is still included in the gross estate at fair market value for estate tax purposes, which is a separate calculation with its own thresholds.
What happens to the step-up if the trust converts through a 721 UPREIT first?
The investor then holds operating partnership units, which are generally eligible for a step-up at death, but they are a partnership interest rather than real property — a distinction with consequences for what heirs can do next.
Where the two horizons diverge
Full-cycle data describes trusts a sponsor has already disposed of and closed. For an investor planning to hold until death rather than until the sponsor's disposition, that record measures a different horizon than the one being planned for. It is still useful context on how a sponsor has handled past exits; it is not a description of a hold that runs decades past a typical business plan. That gap between the sponsor's exit horizon and the investor's own is the part CPAs and estate counsel work through directly, rather than something to infer from a track record built around a different kind of exit.
