A deferred sales trust is an installment-sale arrangement in which you transfer an appreciated asset to an irrevocable third-party trust before closing, the trust sells the asset to your buyer for cash, and the trust pays you back over time through a secured installment note. The point is to spread capital gains tax across many years under Section 453 of the Internal Revenue Code instead of paying it all in the year of sale.1Office of the Law Revision Counsel. 26 USC 453 – Installment Method The tax deferral can be real. So can the costs, the legal uncertainty, and the traps at death.
How the Structure Works
Three parties are involved: you (the seller), an independent trustee, and the trust itself. You create the irrevocable trust and transfer your appreciated asset into it before the sale closes. The trust becomes the legal owner. In exchange, the trust issues you a secured, interest-bearing installment note that promises to pay you back over a set number of years.
The trust then sells the asset to the end buyer for cash. You never touch that cash. Your only claim is against the trust, through the note. The trust must be a non-grantor trust, meaning you cannot retain enough control to be treated as its owner for tax purposes. That separation is what makes the deferral work, and it is also the pressure point where the whole arrangement can fall apart if the paperwork or the facts do not hold up.
How the Tax Deferral Actually Works
Section 453 defines an installment sale as any sale where at least one payment arrives after the tax year in which the sale occurs. Under installment treatment, you recognize gain as you receive principal payments, not when the trust collects the sale price from the buyer. The qualifying installment sale is the one between you and the trust: you gave up the asset, and the trust gave you the note. Because the note pays out over many years, the capital gain is recognized proportionally as payments come in. You report it each year on Form 6252, Installment Sale Income.2Internal Revenue Service. About Form 6252, Installment Sale Income
Every payment you receive has two pieces. The interest portion is ordinary income in the year received. The principal portion splits between tax-free return of basis and a proportional share of the deferred capital gain. Stretching payments across decades can keep you in lower capital gains brackets while the untaxed balance continues compounding inside the trust.
One exception matters and is easy to miss. Depreciation recapture is not deferred. If you claimed depreciation on the asset (common with rental real estate), the recaptured amount is treated as ordinary income in the year of sale regardless of when the installment payments arrive.3Internal Revenue Service.

What You Can Sell Through One
The structure handles a broader asset range than most sellers expect. Investment real estate is the most common use, including commercial buildings, apartment complexes, and land held for investment. Business interests (C-corps, S-corps, LLCs) qualify. So do certain intangibles like patents and copyrights, and high-value collectibles.
A primary residence can go through a DST when the gain exceeds the Section 121 home-sale exclusion, which is $250,000 for single filers and $500,000 for married couples filing jointly who meet the ownership and use tests.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Only the gain above those thresholds is available for deferral.
Section 453 flatly excludes several categories from installment treatment. Publicly traded stock and securities cannot use the installment method; the full gain is recognized in the year of sale. Dealer property (real estate or personal property sold in the ordinary course of a business, like a developer’s lots) does not qualify. Neither does inventory. If your asset falls in any of these categories, a DST will not defer the gain.
How It Differs From a 1031 Exchange
Most sellers considering a DST already know about the Section 1031 like-kind exchange. The two tools serve different situations.
- A 1031 exchange is limited to real property held for investment or business use. A DST can handle businesses, intellectual property, collectibles, and other non-real-estate assets in addition to real estate.
- A 1031 exchange requires you to acquire replacement real estate of equal or greater value. A DST lets the trustee build a diversified financial portfolio with no requirement to stay in real estate.
- A 1031 exchange runs on strict deadlines: 45 days to identify replacement property, 180 days to close. Miss either and the full gain becomes taxable. A DST has no comparable clock.
- In a 1031 exchange, reducing mortgage debt on the way out usually has to be offset by new debt on the replacement property, or the shortfall is taxed as boot. A DST can retire the existing debt on the transferred asset without creating an immediate tax event for you.
The 1031 exchange has one advantage the DST cannot match: decades of case law, regulations, and IRS guidance. The DST does not have that footing.
The Section 453A Interest Charge on Large Sales
If the face amount of your installment note exceeds $5 million, Section 453A imposes an additional interest charge on the deferred tax liability tied to the excess.5Office of the Law Revision Counsel. 26 USC 453A – Special Rules for Nondealers It is not a penalty. It is Congress’s way of charging you for the privilege of deferring a large tax bill.
Each year the obligation is outstanding, you owe interest calculated by applying the IRS underpayment rate to the deferred tax on the portion of the note above $5 million. The underpayment rate moves with federal short-term rates, so the carrying cost of the deferral rises in higher-rate environments. On large sales, this charge can meaningfully erode the compounding benefit that makes the DST attractive in the first place. Any advisor pitching a DST for a sale above $5 million should model this cost in dollars, not gloss over it.
What Happens When You Die
The estate-planning side is where DSTs most often disappoint. Many appreciated assets get a step-up in basis at death, which wipes out the unrealized gain for heirs. Installment notes do not. Under Section 691, an uncollected installment obligation is income in respect of a decedent (IRD).6eCFR. 26 CFR 1.691(a)-5 – Installment Obligations Acquired From Decedent Your heirs inherit the note and owe income tax on the same proportion of each future payment that you would have owed.
No gain is triggered at death from the transfer itself. But the deferred gain does not disappear either. Heirs step into your shoes and keep reporting gain as payments arrive. The note is also included in your gross estate at fair market value, which a professional valuation may discount for illiquidity, below-market interest, and credit risk. That creates a potential double hit: estate tax on the value of the note, and income tax on the future payments. Heirs can deduct the estate tax attributable to the IRD income, which softens the overlap but does not erase it.
If your main goal is passing wealth to the next generation with the lowest total tax, selling outright and paying the capital gains bill can actually leave heirs better off than inheriting a note. This tradeoff needs to be modeled with an estate planning attorney before you commit.
The Legal Risk You Are Accepting
The most important fact about a deferred sales trust is that the IRS has never formally endorsed it. There is no revenue ruling, no published IRS guidance, and no Tax Court decision that specifically approves the structure. “Deferred Sales Trust” is a trademarked brand name, not a category recognized in the tax code. The legal foundation is the general installment sale rules of Section 453, applied through a trust intermediary in a configuration the IRS has neither blessed nor condemned.
Two doctrines create the real exposure. The first is constructive receipt. If the IRS determines you had enough control over the proceeds, or could have received them directly, the entire gain becomes taxable in the year of sale. You cannot serve as trustee, cannot direct investments, and cannot receive back-channel benefits from the trust. Even a loan from the trust back to you can be enough to trigger the doctrine.
The second is the step-transaction doctrine. If the IRS treats your transfer to the trust and the trust’s sale to the buyer as a single prearranged transaction rather than two independent steps, it can collapse the structure and treat you as having sold to the buyer directly. The more tightly the end sale is lined up before the trust exists, the higher this risk gets.
Promoters often point to audits their clients have survived. Surviving an audit is not the same as formal approval, and the IRS is not bound by its handling of any individual case. Go in knowing the deferral is real if the structure holds, and knowing you are accepting legal risk that does not exist with a conventional installment sale or a 1031 exchange.
What It Costs
Setting up a DST typically runs 1% to 2% of the asset’s value in legal and advisory fees, sometimes lower as a percentage on very large deals. On a $5 million sale, that’s $50,000 to $100,000 or more before the note ever pays out.
Ongoing costs stack on top. The independent trustee’s annual fee is often around 0.5% of trust assets. Investment management fees on the trust’s portfolio typically run 0.5% to 1% of assets under management. Some DST structures also include an annuity component to guarantee principal, which brings insurance commissions with it. Over a 15- or 20-year note, layered fees can consume a meaningful share of the compounding benefit the deferral was supposed to produce.
Before signing anything, compare projected total fees over the life of the note against the actual tax savings from deferral. A DST that defers $800,000 of capital gains tax but costs $600,000 in fees over two decades is not the win the pitch deck suggests. Ask for full fee disclosure in writing.
When It Makes Sense, and When It Doesn’t
A DST is strongest when you have a large embedded gain in a concentrated position, want to diversify into liquid investments, and want to spread the tax bill over many years. It particularly earns its keep when a 1031 exchange isn’t available because the asset is a business, intellectual property, or something else outside real estate. Sellers approaching retirement who want to turn a single illiquid asset into a flexible income stream are the classic fit.
It is weakest when heirs would benefit more from a step-up in basis at death, when the note face amount pushes past $5 million and drags in the Section 453A interest charge, or when fees consume too much of the deferral. It is also a poor choice for anyone uncomfortable with legal ambiguity: if the IRS ever issues formal guidance against the structure, unwinding one mid-stream will not be cheap or clean. If you qualify for a 1031 exchange and are content staying in real estate, the exchange will almost always be simpler, cheaper, and legally safer.
