What Is a DST in Tax? Delaware Statutory Trust and 1031 Rules

In tax, DST stands for Delaware Statutory Trust, a legal entity formed under Delaware law that lets multiple investors hold fractional interests in commercial real estate while the IRS still treats each investor as a direct owner of the underlying property. That classification is what makes the structure useful: it preserves the tax treatment of direct real estate ownership, including eligibility for Section 1031 like-kind exchanges, while turning day-to-day management over to a professional trustee.

How a Delaware Statutory Trust Is Built

A DST is formed under Delaware’s Title 12, Chapter 38, which creates an entity legally separate from the people who invest in it.¹ A professional trustee holds legal title to the real estate. Investors, called beneficial owners, hold proportionate interests in the trust’s income and assets. A governing instrument spells out what the trustee can do and what rights the investors have.

A single DST might hold an apartment complex, a medical office building, or an industrial warehouse. Investors collect their share of rental income and claim their share of tax deductions, but they never field a call from a tenant or negotiate a lease.

How the IRS Classifies a DST

The whole tax strategy rests on IRS Revenue Ruling 2004-86, which holds that a properly structured DST is a grantor trust for federal income tax purposes.² Grantor trust status means the IRS looks through the trust and treats each investor as owning an undivided fractional interest in the physical property itself.³

That distinction carries everything. If the IRS classified the trust as a partnership or corporation, income would be taxed at the entity level or investor interests would be treated as business shares rather than real property. Either outcome would end the trust’s usefulness for 1031 exchanges. Because the grantor trust classification makes each investor a direct property owner in the eyes of the IRS, all income, deductions, and credits flow through to each investor’s personal return based on ownership percentage. The trust itself pays no federal income tax.

Using a DST in a Section 1031 Exchange

Section 1031 of the Internal Revenue Code lets you defer capital gains taxes when you sell investment real estate and reinvest the proceeds in like-kind replacement property.⁴ Revenue Ruling 2004-86 confirms that a beneficial interest in a qualifying DST counts as like-kind replacement property, because the IRS views it as direct ownership of real estate rather than a security or business interest.²

For a longtime landlord selling a property with substantial deferred gain, this solves a real problem. You can roll the proceeds into a professionally managed DST, keep the tax deferral, and step out of active property management.

The 45-Day and 180-Day Deadlines

The 1031 timeline is unforgiving. From the day you sell your relinquished property, you have 45 days to identify potential replacement properties in writing. You then have 180 days from the sale date, or the due date of your tax return for that year if it comes first, to close on the replacement property.⁴ Miss either deadline and the entire gain becomes taxable. These deadlines cannot be extended for any reason except presidentially declared disasters.⁵

Part of the appeal of DSTs is that sponsors offer pre-packaged deals already structured and ready to accept investment, which makes hitting these deadlines more realistic than sourcing and negotiating a new property from scratch.

How “Boot” Can Trigger a Tax Bill

You can still owe taxes inside a 1031 exchange if the math doesn’t balance. Any cash you receive, or any reduction in your mortgage debt, creates “boot,” and boot is taxable.⁴ If you sell a property carrying $500,000 in mortgage debt but your DST interest only carries $400,000 in allocated debt, the $100,000 difference is mortgage boot and you owe taxes on it. To fully defer, the replacement property’s equity and debt must equal or exceed the equity and debt of the property you sold. You can offset mortgage boot by adding extra cash to the exchange, but cash boot cannot be offset by taking on additional debt.

Which Taxes a DST Exchange Defers

When a 1031 exchange into a DST works as intended, you defer three separate federal taxes that would otherwise come due on a straight sale:

Long-term capital gains tax. For 2026, the federal rate is 0%, 15%, or 20% depending on taxable income. Most investors selling substantial investment property land in the 15% or 20% bracket.
Depreciation recapture tax. If you claimed depreciation deductions on the property, the IRS taxes those previously claimed deductions at a maximum rate of 25% when you sell. This is unrecaptured Section 1250 gain.
Net investment income tax. High-income investors pay an additional 3.8% tax on the lesser of net investment income or the amount their modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). These thresholds are not adjusted for inflation.⁶⁷

An investor in the 20% capital gains bracket who also owes the 3.8% NIIT and faces 25% depreciation recapture can see a combined federal tax bite approaching 30% or more on portions of the sale proceeds. A DST exchange defers all of it. The word is defer, not eliminate. Those taxes come due whenever the investor eventually sells without rolling into another exchange.

How DST Income and Depreciation Are Reported

Because the IRS treats DST investors as direct property owners, each investor claims their own depreciation deductions. When a DST is acquired as replacement property in a 1031 exchange, the investor’s adjusted cost basis carries forward from the relinquished property and continues depreciating on the same schedule. Any additional basis created by higher debt in the replacement property starts a new depreciation schedule: 27.5 years for residential property or 39 years for commercial property. These deductions offset rental income on the investor’s return, often reducing or eliminating current tax liability on DST distributions.

Investors report their share of DST income and expenses on Schedule E of Form 1040.⁸ One detail catches people off guard: DST investors receive a grantor trust letter rather than the Schedule K-1 that partnership investors get. The letter reports the investor’s share of income and expenses but does not include depreciation figures. Each investor’s depreciation depends on their own carried-forward basis from the 1031 exchange, so the trust cannot calculate it for them. The DST usually provides the percentage allocation among land, building, and personal property so the investor and their preparer can run the numbers.

Investors must also file a state return in every state where the DST holds property, even if they live elsewhere. A DST that owns properties in three states creates three state filing obligations on top of the home state return.

Rules the Trust Must Follow to Keep Its Status

To keep its grantor trust status and remain eligible for 1031 exchanges, a DST must follow restrictions practitioners call the Seven Deadly Sins. They come directly from Revenue Ruling 2004-86, and violating any of them can get the trust reclassified as a business entity, which ends its tax benefits:²

No new capital contributions once the offering closes.
No new financing or refinancing of the existing loan, except in narrow circumstances like a loan default.
No renegotiation of existing leases and no new leases, unless a tenant defaults or goes bankrupt.
Mandatory cash distributions at least quarterly, less reasonable reserves.
Reserves held only in short-term investments or government securities.
Capital improvements limited to normal repairs, non-structural work, or work legally required.
No reinvestment of proceeds if the trust sells the property.

These constraints make a DST fundamentally different from a REIT or a real estate partnership. A REIT can buy and sell properties, renegotiate financing, and sign new tenants. A DST cannot. The trade-off for the tax treatment is a locked-in, passive investment.

Most DSTs use a master lease to work within these restrictions. A master tenant, usually an entity affiliated with the sponsor, signs a single lease with the trust and then subleases individual units to the actual occupants. The DST itself has only one tenant and one lease, so when occupants turn over the master tenant handles the new leases without the DST ever entering into a new lease agreement.

How the Deferral Ends

DST investments typically last five to ten years, ending when the trust sells the underlying property in what is called a full-cycle event. At that point investors have three options:

Cash out. Take the sale proceeds as a distribution. This triggers all the capital gains taxes and depreciation recapture deferred through the original 1031 exchange. For investors who have done multiple sequential exchanges over decades, the accumulated deferred gain can be large.
Roll into another 1031 exchange. Reinvest the proceeds in a new DST or another qualifying property to keep deferring taxes. The same 45-day and 180-day deadlines apply. You cannot touch the proceeds directly; the funds must flow through a qualified intermediary or the exchange fails.⁵
Convert to an UPREIT through a 721 exchange. Some DSTs offer the option of contributing the property into an umbrella partnership real estate investment trust. Investors receive operating partnership units that function similarly to REIT shares. The conversion is tax-deferred and effectively ends the 1031 exchange cycle, moving the investor into a more liquid investment without triggering an immediate tax bill.

For investors who hold until death, the deferred gain may be eliminated through a stepped-up basis, which is one reason financial advisors sometimes describe the strategy as “defer, defer, die.”

Who Can Invest in a DST

DST offerings are private placements sold under Regulation D of the Securities Act of 1933. Participation is limited to accredited investors, defined under Rule 501 of Regulation D as individuals with a net worth exceeding $1 million (excluding the primary residence) or annual income exceeding $200,000 individually, or $300,000 jointly with a spouse, in each of the two most recent years, with a reasonable expectation of the same income in the current year.⁹

Risks That Come With the Tax Benefits

The tax treatment is real, and so are the risks. DSTs are illiquid. There is no meaningful secondary market for DST interests, so if you need your capital back before the full-cycle event, you are largely stuck. You have no control over property management, no vote on whether to sell or refinance, and no way to force a distribution.

Performance depends on the sponsor’s competence and the underlying real estate market. Economic downturns, rising interest rates, and local market shifts all affect property values and rental income. Investors can and do lose principal. Sponsor fees for acquisition and asset management reduce returns. And the operational restrictions that protect the trust’s tax status also prevent the trustee from responding flexibly to market changes. If the largest tenant leaves, the trust cannot aggressively renegotiate lease terms to fill the space; it has to wait for the lease to formally expire or for the tenant to default.

Sequential 1031 exchanges also create a growing deferred tax liability. Each exchange carries the original basis forward, and the accumulated gain compounds. If an investor eventually cashes out rather than rolling into another exchange or converting to an UPREIT, the resulting tax bill reflects every deferral that came before it.
