How deferred sales trusts and installment sales work

Quick answer: A "deferred sales trust" is a marketed name for an arrangement built on the installment-sale rules under IRC Section 453 — it lets a seller spread capital gain recognition over time by receiving payments from a trust instead of a lump sum at closing. The IRS publications provided don't use the term "deferred sales trust," but the underlying mechanics come from the installment sale rules in Publication 537.

What it is

An installment sale, as defined by the IRS, is simply a sale of property where you receive at least one payment after the tax year of the sale.¹ Under that method, if you realize a gain on an installment sale, you may be able to report part of your gain when you receive each payment. This method of reporting gain is called the installment method.² A "deferred sales trust" typically layers a trust as an intermediary that receives the sale proceeds and then pays the original seller over time under a note — structurally similar to an installment sale, but routed through a trust rather than directly from buyer to seller.

How it works — the mechanics that matter

• Escrow/trust arrangements can defeat installment treatment if not structured carefully. If the sales agreement calls for the buyer to establish an irrevocable escrow account from which the remaining installment payments (including interest) are to be made, these sales can't be reported on the installment method.³ That's because the buyer's obligation is paid in full when the balance of the purchase price is deposited into the escrow account. When an escrow account is established, you no longer rely on the buyer for the rest of the payments, but on the escrow arrangement.⁴
• There is a narrow exception. If an escrow arrangement imposes a substantial restriction on your right to receive the sale proceeds, the sale can be reported on the installment method, provided it otherwise qualifies. For an escrow arrangement to impose a substantial restriction, it must serve a bona fide purpose of the buyer, that is, a real and definite restriction placed on the seller or a specific economic benefit conferred on the buyer.⁵ A trust structure marketed as a "deferred sales trust" would need to satisfy this kind of restriction to preserve deferral — otherwise the full gain could be taxed immediately, as in the escrow example below.
• Large sales can trigger an interest charge on the deferred tax. If the sales price exceeds $150,000, and the total balance of all nondealer installment obligations arising during, and outstanding at the close of, the tax year is more than $5 million⁶, the seller must pay interest on the deferred tax related to any obligation that arises during a tax year from the disposition of property under the installment method⁷.
• Pledging the note as collateral can accelerate gain. If you use an installment obligation to secure any debt, the net proceeds from the debt may be treated as a payment on the installment obligation. This is known as the pledge rule, and it applies if the selling price of the property is over $150,000.⁸ This matters because some deferred-sales-trust arrangements involve the seller borrowing against the trust's note.

Example (illustrative, from the documents)

Publication 537 shows what happens when a trust-like escrow fails the test: you sell property for $100,000. The sales agreement calls for a down payment of $10,000 and payment of $15,000 in each of the next 6 years to be made from an irrevocable escrow account containing the balance of the purchase price plus interest. You can't report the sale on the installment method because the full purchase price is considered received in the year of sale.⁹ This illustrates the core risk: if the trust arrangement is deemed to have taken the seller out of the buyer's credit risk, deferral disappears entirely.

Risks and limits

• Escrow/trust structures that pay off the buyer's obligation in full up front destroy installment deferral.
• The $5 million pledge/interest-charge rules can impose real carrying costs on large transactions.
• None of the provided documents address the specific "deferred sales trust" product as marketed by promoters, its use of an independent third-party trustee, or IRS rulings (if any) blessing that specific structure.

In practice

These rules can defer recognition of gain — they don't eliminate it. The character of the gain (capital vs. ordinary) carries over to the payments received. Whether a given trust structure actually qualifies depends heavily on drafting and facts not covered in these documents.

Given the complexity and audit risk of trust-based deferral structures, this is a case where getting advice from a CPA or tax attorney who can review the actual trust documents is essential before proceeding.
