How do Deferred Sales Trusts utilize Section 453 to defer capital gains taxes?

Question

Tyler Smith · Accepted Answer

A Deferred Sales Trust (DST) is a specialized wealth planning tool designed to defer capital gains taxes by integrating IRC Section 453 installment sale rules with a third-party non-grantor trust.

How the Structure Functions
In a standard cash sale, capital gains taxes are triggered immediately upon closing. Under a DST framework, the transaction occurs in two distinct steps:
1. Sale to the Trust: Prior to closing with the end buyer, the seller enters into an installment contract with an independent, third-party non-grantor trust, selling the property or business in exchange for a term promissory note.
2. Sale to the Ultimate Buyer: The trust then sells the asset to the third-party cash buyer for the negotiated market price. Because the trust purchased the asset at fair market value immediately prior, the trust realizes zero taxable gain on its subsequent sale.

Tax Mechanics and Compliance
The seller does not receive the cash proceeds directly, avoiding constructive receipt. Gain recognition is deferred under Section 453 until the trust distributes principal payments to the seller according to the promissory note terms. In the interim, trust assets can be invested across diversified liquid portfolios to generate income that funds note payments.

Critical Risk Factors
Unlike traditional seller financing, a DST introduces significant regulatory scrutiny. The IRS examines these transactions to confirm that the trustee is truly independent, that the seller holds no managerial control over trust investments, and that the arrangement is not an abusive tax shelter. Sellers must work with experienced tax counsel to ensure the structure satisfies IRC Section 453 substance over form requirements.
