Capital Gains Deferral, Compared: SIS vs DST vs 1031 vs OZ vs CRT

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.

The five structures at a glance

StructureHow it defersRequiresIRS standing
Structured Installment Sale (§453)Spread proceeds over years; taxed as receivedNothing to buy; carrier-funded paymentsBuilt on the §453 statute — recognized
1031 ExchangeRoll gain into like-kind real propertyReplacement property within 45/180 daysWell-established (real property only)
Deferred Sales TrustTrust buys/resells; pays you over timeThird-party trust + trusteeGray area — no IRS ruling
Opportunity ZoneDefer + potential step-upInvest in a QOF; current designations sunset after 2026Statutory but time-limited
Charitable Remainder TrustDefer + income + charityIrrevocable trust; charitable intentWell-established

How to choose

The honest bottom line:
  • The §453 structured installment sale is the most flexible and among the most conservative.
  • A 1031 is excellent — but only for like-kind real estate, on a tight clock.
  • DSTs and monetized arrangements carry the most IRS uncertainty.

The takeaway

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.

Frequently asked questions

What is the best way to defer capital gains tax on a sale?

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.

What is the difference between a 1031 exchange and a structured installment sale?

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.

Is a Deferred Sales Trust as safe as a 1031 or a structured installment sale?

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.

Can I still use an Opportunity Zone to defer gains?

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.

Which deferral structures work for selling a business?

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.
