A Deferred Sales Trust is a tax strategy that uses the installment sale rules in Section 453 of the Internal Revenue Code to spread capital gains tax on the sale of an appreciated asset over many years instead of paying it all at closing. You transfer the asset to an irrevocable trust before the sale, the trust sells it to the buyer for cash, and the trust pays you back over time through a secured, interest-bearing installment note. You recognize gain only as principal payments arrive, which can keep you in lower tax brackets and let the full sale proceeds continue compounding inside the trust.
The structure can deliver real tax deferral and investment flexibility that a 1031 exchange cannot match. It also carries ongoing fees, estate-planning tradeoffs, and legal uncertainty that a conventional installment sale does not.
How the Structure Works
Three parties are involved: you (the seller), an independent third-party trustee, and the irrevocable trust itself. Before any sale closes, you create the trust and transfer your appreciated asset into it. The trust becomes the legal owner. In exchange, the trust issues you a secured installment note promising to pay you back over an agreed schedule, with interest.
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 is set up as a non-grantor trust, meaning you cannot retain enough control over it to be treated as its owner for tax purposes. That separation between you and the proceeds is what makes the deferral work.
Why the Tax Gets Deferred
The tax logic rests on Section 453, which governs installment sales. An installment sale is any sale where at least one payment arrives after the end of the tax year in which the sale occurs.1Office of the Law Revision Counsel. 26 USC 453 – Installment Method Under installment treatment, you report gain as you actually receive principal payments, not when the trust collects the full sale price from the buyer.
The qualifying installment sale is the one between you and the trust. You transferred the asset; the trust gave you a note. Because that note pays out over years or decades, the gain gets recognized in proportion to what you receive each year. You report it annually on Form 6252, Installment Sale Income.2Internal Revenue Service. About Form 6252, Installment Sale Income
Each payment has two components. The interest portion is taxed as ordinary income in the year you receive it. The principal portion is split between a tax-free return of your original basis and a proportional share of the deferred capital gain.
One important carve-out: depreciation recapture does not get deferred. If you previously claimed depreciation on the asset, as is common with rental property, the recaptured depreciation is treated as ordinary income in the year of sale regardless of when installment payments arrive.3Internal Revenue Service.

What You Can Sell Through One
The DST structure accepts a broader range of assets than most sellers expect. Highly appreciated investment real estate is the most common case, including commercial buildings, apartment complexes, and raw land held for investment. Business interests such as C-Corporations, S-Corporations, and LLCs also qualify, as do certain intangible assets like patents or copyrights and high-value collectibles.
A primary residence can also be sold through a DST when the gain exceeds the home-sale exclusion. Single filers can exclude up to $250,000 of gain from selling a principal residence, and married couples filing jointly can exclude up to $500,000 if they meet ownership and use requirements.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Any gain above those thresholds is eligible for deferral through a DST.
Section 453 excludes several categories from installment treatment:
- Publicly traded securities. Stock or securities traded on an established market cannot use the installment method, and the full gain is recognized in the year of sale.1Office of the Law Revision Counsel. 26 USC 453 – Installment Method
- Dealer property. Real estate or personal property sold in the ordinary course of a business, like a developer selling lots, is ineligible.
- Inventory. Property that would be counted as inventory at year-end is excluded.
What Happens to the Money Inside the Trust
Once the trust collects the sale proceeds, the trustee invests them according to the trust agreement and the terms of your installment note. The money does not have to go back into real estate. The trustee can build a portfolio of stocks, bonds, mutual funds, or other financial instruments. For sellers who are tired of managing property or want to shift into more liquid holdings, that flexibility is often the main draw.
Your payment schedule is set by the installment note. It can be fixed, variable, or tied to a milestone such as retirement. The goal is to match actual income needs while keeping each year’s taxable gain manageable.
The compounding advantage is the core economic argument. Because the trust holds the full sale proceeds and only pays you incrementally, the entire principal stays invested and growing. If you had sold directly, capital gains tax would have shrunk the invested amount from day one. Whether that compounding benefit outweighs the costs and risks depends on the size of the gain, the length of the deferral, and the trust’s investment returns.
How It Compares to a 1031 Exchange
Most sellers weighing a DST are also considering a Section 1031 like-kind exchange, which is the more familiar deferral tool for real estate. The two serve different situations.
- Asset eligibility. A 1031 exchange is limited to real property held for investment or productive use in a business. A DST can handle businesses, personal property, intellectual property, and collectibles in addition to real estate.
- Reinvestment. A 1031 requires acquiring replacement real estate of equal or greater value. A DST lets the trustee invest in a diversified financial portfolio with no requirement to stay in real estate.
- Timing. In a 1031 exchange you must identify replacement property within 45 days and close within 180 days, and missing either deadline makes the entire gain taxable. A DST has no comparable deadlines.
- Debt. In a 1031, any reduction in mortgage debt from the sold property typically must be offset by new debt on the replacement, or the difference is taxed as “boot.” A DST can retire existing debt on the transferred asset without creating an immediate tax event for you.
The 1031 has one decisive advantage: it is an established, IRS-sanctioned strategy with decades of case law and regulatory guidance. The DST does not share that legal certainty.
The $5 Million Interest Charge
If the face amount of your installment note exceeds $5 million, Section 453A imposes an additional interest charge on the deferred tax liability.5Office of the Law Revision Counsel. 26 USC 453A – Special Rules for Nondealers This is not a penalty. It is Congress compensating the government for letting you defer a large bill.
The charge applies to the portion of the obligation above $5 million. Each year the obligation remains outstanding, you owe interest calculated by multiplying the deferred tax liability on the excess by the IRS underpayment rate for that period. The underpayment rate moves with federal short-term rates, so the carrying cost rises when rates are high. For large sales, this charge can meaningfully erode the compounding benefit. Any advisor proposing a DST above $5 million should model it explicitly.
What Happens When You Die
This is one of the most misunderstood parts of the DST. Many appreciated assets receive a step-up in basis at death that wipes out the unrealized gain for heirs. Installment notes do not. Under Section 691, an uncollected installment obligation is treated as income in respect of a decedent, or 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 simply because the note transfers to your estate or heirs. But the deferred gain does not disappear. Your heirs step into your shoes and continue reporting gain as payments arrive. The note is also included in your gross estate for federal estate tax purposes, valued at fair market value rather than face value, with professional valuations typically applying discounts for illiquidity, below-market interest rates, and credit risk.
The result is a potential double-tax problem: estate tax on the note’s value, income tax on the future payments. Heirs can deduct the estate tax attributable to the IRD income, which partially offsets the overlap but does not eliminate it. If your primary goal is passing wealth to the next generation tax-free, selling the asset outright and paying the capital gains tax may actually leave heirs in a better position than inheriting a DST note. Model this tradeoff carefully with an estate planning attorney before committing.
The Legal Risk You’re Accepting
The most important thing to understand is that the IRS has never formally endorsed the strategy. There is no revenue ruling, no published IRS guidance, and no Tax Court decision that specifically blesses the DST structure. The term “Deferred Sales Trust” itself is a trademarked brand name, not a category of trust recognized in the tax code. The legal foundation rests on the general installment sale rules of Section 453, applied through a trust intermediary in a way the IRS has not explicitly approved or disapproved.
Two doctrines pose the greatest risk:
- Constructive receipt. If the IRS determines you had sufficient control over the sale proceeds, or could have received them directly, the entire gain becomes taxable in the year of sale. You must have no control over the trust, cannot serve as trustee, and cannot direct how the proceeds are invested. Even indirect control, like having the trust loan funds back to you, could trigger this doctrine.
- Step-transaction doctrine. If the IRS views the 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 directly to the buyer. The more the sale to the end buyer is lined up before the trust is created, the higher this risk.
DST promoters often point to successful audits as evidence the strategy works. Surviving an audit is not the same as formal approval, and the IRS’s treatment of any individual case does not bind it in future cases. Go in knowing the deferral benefit is real if the structure holds up, and that you are accepting legal risk that does not exist with a conventional installment sale or a 1031 exchange.
What It Costs
Setting up and running a DST is not cheap. Legal and advisory fees to create the trust, draft the installment note, and structure the transaction typically run 1% to 2% of the asset’s value, with higher-value assets sometimes at a lower percentage. On a $5 million sale, expect $50,000 to $100,000 or more just to put the structure in place.
Ongoing costs include the independent trustee’s annual fee, often around 0.5% of trust assets, and investment management fees from the advisor running the portfolio, typically 0.5% to 1% of assets under management. Some structures include an annuity component to guarantee principal, which adds insurance commissions. Over a 15- or 20-year note, these layered fees can consume a meaningful share of the compounding benefit.
Before signing anything, compare total projected fees over the life of the note against actual tax savings from deferral. A DST that defers $800,000 in capital gains tax but costs $600,000 in fees over two decades is a very different proposition than the marketing suggests. Ask for a full fee disclosure in writing.
When It Fits and When It Doesn’t
The DST is strongest for sellers with a large embedded gain who want to exit a concentrated position, diversify into liquid investments, and spread the tax bill over many years. It works particularly well when a 1031 exchange is not available because the asset is a business, intellectual property, or another non-real estate holding. Sellers approaching retirement who want to turn a single illiquid asset into a flexible income stream are the classic case.
The DST is weakest when your heirs would benefit more from a step-up in basis at death, when the sale amount triggers the Section 453A interest charge, or when the fees eat too deeply into the deferral benefit. It is also a poor fit for anyone uncomfortable with legal ambiguity. If the IRS ever issues formal guidance against the structure, unwinding a DST mid-stream could be expensive and disruptive. Sellers who qualify for a 1031 exchange and are comfortable staying in real estate will almost always find the exchange simpler, cheaper, and legally safer.
