The IRS has never issued a revenue ruling, regulation, or other binding guidance approving or rejecting the Deferred Sales Trust. That is the honest answer to the question of whether there is an IRS ruling on a Deferred Sales Trust. The structure relies on the general installment sale rules of Internal Revenue Code Section 453, and each transaction stands or falls on its own facts if the IRS decides to look at it. In August 2023, Treasury proposed regulations that would classify closely related “monetized installment sale” arrangements as listed transactions, which narrows the ground DST promoters have relied on.
What the IRS Has and Has Not Issued
Promoters often point to “favorable IRS rulings” as evidence that the DST is blessed. The documents they cite are Private Letter Rulings issued to specific taxpayers about their own installment sale facts. A PLR applies only to the taxpayer who requested it and cannot be used as precedent by anyone else. No PLR addresses the branded Deferred Sales Trust product by name.
What those PLRs confirm is narrow and unremarkable: a promissory note that meets the statutory requirements of Section 453 is not treated as payment in the year of sale. The IRS has held that view for installment sales generally for decades. The open question with a DST is whether inserting a trust as an intermediary buyer is respected as a real transaction or collapsed as a device to avoid tax.
The absence of a revenue ruling matters. A revenue ruling would be binding authority the public could rely on. Published regulations would define when a trust-based installment sale qualifies and when it does not. Neither exists for the DST. Silence is not approval; it means the structure has not been endorsed and has not been formally rejected either.
The Statutory Basis: IRC Section 453
A DST is not authorized by any special code section. It uses the ordinary installment sale method. Under Section 453, a seller who receives at least one payment after the year of sale reports the gain proportionally as payments come in, rather than all at once.1Office of the Law Revision Counsel. 26 USC 453 Installment Method The method applies automatically to qualifying sales unless the taxpayer elects out.
For the method to work, the promissory note the seller receives cannot itself be treated as payment. A note that is payable on demand, or that is readily tradable on an established securities market, is treated as immediate payment and blows up the deferral.1Office of the Law Revision Counsel. 26 USC 453 Installment Method A DST note has to avoid both traits.
Some property is excluded from installment treatment entirely. Dealer dispositions and inventory do not qualify.2Office of the Law Revision Counsel. 26 USC 453 Installment Method A developer selling lots from a subdivision, for instance, cannot use the installment method for those sales, and running the deal through a DST does not change that.
The mechanics of the DST itself are straightforward. The seller transfers a highly appreciated asset to an irrevocable trust in exchange for a promissory note. The trust, acting through an independent trustee, sells the asset to a third-party buyer for cash. Because the seller received a note rather than cash, the theory is that no gain is recognized until the trust makes payments on the note. Everything depends on the trust being a genuine buyer rather than the seller’s agent.
The Monetized Installment Sale Proposed Regulations
The most consequential IRS development for anyone considering a DST came on August 4, 2023, when Treasury published proposed regulations that would identify “monetized installment sales” as listed transactions.3Federal Register. Identification of Monetized Installment Sale Transactions as Listed Transactions A listed transaction is one the IRS has determined to be abusive. Participating in one triggers mandatory disclosure and severe penalties if the disclosure is not made.
The targeted arrangement works like this: a seller uses an intermediary to structure an installment sale, then receives a loan for essentially the full amount of the deferred proceeds. The seller has the cash on day one but reports the transaction as an installment sale. The IRS’s position is that the intermediary is not a genuine buyer, the loan is not a real loan, and the whole structure exists to avoid tax.3Federal Register. Identification of Monetized Installment Sale Transactions as Listed Transactions
The proposed regulations reach transactions that are “substantially similar” to the described arrangement, and that phrase is deliberately broad. A DST paired with a same-day loan against the note or the trust’s assets would almost certainly be caught. Even without an explicit loan, if the seller has practical access to the trust proceeds on demand, the IRS can argue the economic substance is the same. DST promoters draw a line between their product and a monetized installment sale by pointing out that a properly structured DST does not include a loan back to the seller. That distinction may hold, but no court has confirmed it and no IRS guidance endorses it.
Penalties If the Structure Is a Listed Transaction
Under Section 6707A, failing to disclose participation in a listed transaction can cost individuals up to $100,000 per failure and entities up to $200,000.4Office of the Law Revision Counsel. 26 US Code 6707A – Penalty for Failure to Include Reportable Transaction Information With Return The IRS also gets an extended statute of limitations to assess tax on undisclosed listed transactions, so the audit window runs well past the usual three years.
Doctrines the IRS Can Use to Collapse a DST
Even setting aside the monetized installment sale regulations, the IRS has several general doctrines available to unwind a DST that lacks substance.
The economic substance doctrine, codified at Section 7701(o), lets the IRS deny tax benefits from a transaction that does not change the taxpayer’s economic position in a meaningful way beyond the tax savings. A DST that produces no business result other than deferring tax is squarely in the doctrine’s crosshairs.
The grantor trust rules under Sections 671 through 679 are another lever. If the seller retains too much control over the trust or its assets, the trust’s income and transactions are attributed back to the seller.5Office of the Law Revision Counsel. 26 USC 671 Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners The trust’s immediate cash sale is then treated as the seller’s own sale, and the full gain is taxed in year one.
The step transaction doctrine allows the IRS to combine prearranged steps that lack independent purpose into a single transaction. If the transfer to the trust and the resale to the end buyer are two parts of one plan, the IRS can treat the seller as having sold directly to the end buyer, with the trust ignored.
An agency argument is a related risk. If the trust simply carries out the seller’s instructions rather than acting as a genuine buyer, the IRS can treat the trust as the seller’s agent and tax the whole gain up front.
Structural Requirements That Determine Whether the DST Holds Up
Because the IRS has not blessed the structure in the abstract, everything comes down to how the specific transaction is set up. Getting any of the following wrong does not just weaken the position; it can cause the full capital gain to be recognized in the year of the original transfer.
- Trustee independence. The trustee must be unrelated to the seller and must exercise real fiduciary control. The seller cannot direct investment decisions or dictate the timing of payments beyond the terms of the note.
- Promissory note terms. The note must be unsecured and non-recourse. It cannot be payable on demand or readily tradable. The term should be commercially reasonable, and the interest rate must meet or exceed the Applicable Federal Rate to avoid imputed interest under Section 483. For April 2026, the long-term AFR is 4.62% compounded annually.6eCFR. 26 CFR 1.483-1 Interest on Certain Deferred Payments7Internal Revenue Service. Rev. Rul. 2026-7 Applicable Federal Rates
- No seller control over proceeds. Once the trust has cash, the seller cannot direct how it is invested. Evidence that the seller is managing the portfolio gives the IRS an agency argument.
- No indirect security. The note cannot be secured by cash or cash equivalents. If the trust’s assets effectively guarantee the note, the IRS can treat the note as immediate payment.
- Real economic activity. The trustee should actively manage the assets and bear investment risk. A trust that exists only on paper is the easiest kind for the IRS to collapse.
Failure on any of these points gives the IRS a path to recharacterize the deal. The result is uniform: capital gains tax on the full amount in the year of the original transfer, plus interest, plus potential accuracy-related penalties.
Costs That Cut Into the Deferral
Industry sources put upfront legal and structuring fees at roughly 1.25% to 1.5% of the transaction value. On a $5 million sale, that is $62,500 to $75,000 before anything else. Annual trustee, administrative, tax, and investment management fees can run another 1% to 3% of trust assets per year. Over a 15-year note, cumulative fees can consume a meaningful share of what deferral was supposed to save.
Large deals carry a separate cost written into the code. Section 453A imposes an interest charge on the deferred tax when the face amount of installment obligations from a tax year that remain outstanding at year-end exceeds $5 million, on property with a sales price above $150,000.8Office of the Law Revision Counsel. 26 US Code 453A – Special Rules for Nondealers The charge applies to the portion above $5 million, multiplied by the IRS underpayment rate, every year the obligation is outstanding. A $20 million note would trigger the charge on $15 million of deferred gain annually.
The audit risk itself is a cost. Because no binding guidance validates the structure, every participant carries the possibility that the IRS challenges the deal years later. If the IRS wins, the seller owes the full tax from year one, plus interest running from that date, plus penalties. Audit defense is expensive even when the taxpayer prevails.
The DST market is dominated by a small network of promoters who control the trust documents and trustee relationships. Independent evaluation of those documents is limited because they are not standardized or publicly available. Before signing, sellers should retain tax counsel with no financial connection to the promoter to review the specific structure against the requirements above.
How a DST Compares to a 1031 Exchange for Real Estate Sellers
Real estate sellers weighing the risk of a DST usually ask about the alternative. A 1031 like-kind exchange applies only to real property held for investment or productive use in a trade or business. The seller must identify replacement property within 45 days and close within 180 days of transferring the relinquished property, and the replacement must be of equal or greater value to defer the full gain.9Office of the Law Revision Counsel. 26 US Code 1031 – Exchange of Real Property Held for Productive Use in a Trade or Business or for Investment Missing either deadline kills the exchange.
A DST has no reinvestment deadline and no like-kind requirement. The trust can hold stocks, bonds, or other investments. The trade-off is legal certainty. Section 1031 rests on a statute with decades of case law, published regulations, and consistent IRS guidance. The DST rests on an interpretation of the installment sale rules that no court has validated and no binding IRS guidance addresses. For sellers who can find qualifying replacement property within the deadlines, the 1031 exchange is the more conservative path.
