Five legitimate-sounding ways to defer the tax on a sale — but they differ wildly in risk, flexibility, and what they require of you. Here's an honest side-by-side, including the IRS-scrutiny differences the promoters won't mention.
When you're facing a big capital gain, you'll hear about several deferral structures. They are not interchangeable. Here's an honest comparison of the five most common — including which ones the IRS has been scrutinizing.
| Structure | How it defers | Requires | IRS standing |
|---|---|---|---|
| Structured Installment Sale (§453) | Spread proceeds over years; taxed as received | Nothing to buy; carrier-funded payments | Built on the §453 statute — recognized |
| 1031 Exchange | Roll gain into like-kind real property | Replacement property within 45/180 days | Well-established (real property only) |
| Deferred Sales Trust | Trust buys/resells; pays you over time | Third-party trust + trustee | Gray area — no IRS ruling |
| Opportunity Zone | Defer + potential step-up | Invest in a QOF; current designations sunset after 2026 | Statutory but time-limited |
| Charitable Remainder Trust | Defer + income + charity | Irrevocable trust; charitable intent | Well-established |
The "best" deferral structure depends on what you're selling, whether you want to keep owning, and how much tax risk you'll accept. For most sellers of a business, land, stock, or a property they want to exit, a structured installment sale is the cleanest fit. Run your numbers before you decide.
It depends on the asset. For real estate you want to keep, a 1031 exchange. For a business, land, stock, or property you want to exit, a structured installment sale under §453 is usually the most flexible and conservative. A charitable remainder trust fits charitable goals.
A 1031 defers tax only if you reinvest in like-kind real estate within strict deadlines. A structured installment sale spreads the gain over years without buying anything and works for assets a 1031 can't cover, like a business or stock.
Generally no. 1031 exchanges and structured installment sales rest on well-established statute, while Deferred Sales Trusts operate in a gray area without a specific IRS ruling and have drawn enforcement scrutiny of related arrangements.
Opportunity Zones remain available, but the current zone designations are set to sunset after 2026 and the benefit structure changes over time. They require investing in a Qualified Opportunity Fund, unlike a structured installment sale.
A 1031 exchange does not work for a business sale (it's for like-kind real estate). A structured installment sale, a charitable remainder trust, or in some cases an Opportunity Zone investment can defer gain from a business sale.
