Choosing between a deferred sales trust and a 1031 exchange comes down to what you’re selling, whether you want to stay in real estate, and how much legal uncertainty you can live with. A 1031 exchange is the older, safer route: sell investment real estate, buy replacement real estate, and defer the capital gains tax indefinitely. A deferred sales trust is more flexible, working with almost any appreciated asset and letting you diversify out of real estate, but it relies on a structure the IRS has publicly criticized and proposed to flag as a listed transaction. For most investors staying in real estate, the 1031 exchange wins on cost, certainty, and estate planning. For sellers of businesses, practices, or other assets that don’t qualify for 1031 treatment, the installment trust may be the only deferral option available, and it deserves careful legal review before you commit.
How Each One Defers the Tax
The two strategies solve the same problem through different mechanics.
A 1031 exchange, authorized by Section 1031 of the Internal Revenue Code, lets you sell investment real estate and roll the proceeds into replacement real estate of equal or greater value without paying capital gains tax at the time of the swap.1Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Your original cost basis carries into the new property. The tax isn’t erased, just postponed until you eventually sell without exchanging again.
A deferred sales trust relies on Section 453, the installment sale rules.2Office of the Law Revision Counsel. 26 USC 453 – Installment Method You sell your asset to a trust in exchange for an installment note, and the trust then sells the asset to the end buyer. Because you’re paid over time rather than in a lump sum, you recognize gain only as payments come in. The trust invests the proceeds and pays you on a schedule that can stretch over decades.
What You Can Sell With Each
Asset scope is where these two strategies split most sharply.
Section 1031 is limited to real property held for investment or business use. Rental houses, commercial buildings, and raw land all qualify. Personal residences do not, though a vacation property can qualify under a safe harbor if it’s rented at fair market value for at least 14 days per year and personal use stays below the greater of 14 days or 10 percent of the days rented.1Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Before 2018, personal property like equipment could be exchanged, but the Tax Cuts and Jobs Act narrowed the section to real estate only. Foreign real estate is also out; domestic and overseas real property are not considered like-kind.
The installment sale rules cover much broader ground. You can use an installment structure for a private business, a professional practice, a partnership interest, artwork, a patent, or a primary residence where the gain exceeds the Section 121 exclusion of $250,000 for single filers or $500,000 for married couples filing jointly.3Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence For many of these assets, an installment sale is the only deferral option that exists.
One important exclusion: publicly traded stock and securities can’t use the installment method. Section 453(k) requires the full gain to be recognized in the year of sale.2Office of the Law Revision Counsel. 26 USC 453 – Installment Method Whether cryptocurrency traded on major exchanges falls under that same exclusion is unsettled, and anyone considering an installment sale of crypto should get a written tax opinion first.
What You Can Do With the Money Afterward
A 1031 exchange keeps your capital in real estate. Full stop. Replacement property must be equal or greater in value, must be held for investment or business use, and any cash you pocket or debt you shed becomes taxable “boot” in the year of the exchange. If you want to exit real estate, a 1031 exchange won’t help you.
A deferred sales trust unlocks diversification. Once the trust sells the asset, the proceeds can be invested in stocks, bonds, mutual funds, or a mixed portfolio managed by the trustee. You’re no longer tied to a single property, a single sector, or a single market. Payments come out of the trust on the installment schedule, and you owe tax only on the gain portion of what you receive.2Office of the Law Revision Counsel. 26 USC 453 – Installment Method Take interest-only payments and the principal stays inside the trust, with the deferral continuing.
Because payments are spread over years, an installment structure also lets you manage your annual bracket. Long-term capital gains hit 20 percent, with a 3.8 percent net investment income tax on top for higher earners.4Internal Revenue Service. Topic No. 559, Net Investment Income Tax Careful payment sizing can keep more of your gain in the 15 percent bracket and below the NIIT threshold. A 1031 exchange doesn’t offer that lever because the whole gain is deferred at once.
Deadlines That Apply to One and Not the Other
The 1031 exchange runs on strict clocks that catch people out.
From the day you close on the sale of your old property, you have 45 calendar days to identify replacement properties in writing, and 180 days total from the sale to close on the replacement.5Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031 These windows run concurrently. If your tax return due date falls before day 180, the exchange period ends on the return due date unless you extend. Miss either deadline and the exchange dies, making the full gain immediately taxable.
Most investors identify replacements under the three-property rule, which allows up to three candidates regardless of combined value. Alternatives exist, but the three-property rule is the workhorse because the fallback options either cap total value or require you to actually acquire 95 percent of what you named.
The deferred sales trust has no reinvestment deadline. Because deferral is tied to when you receive payments rather than when you replace an asset, there’s no 45-day scramble and no 180-day closing pressure. In hot markets where replacement properties are scarce or overpriced, that absence of a ticking clock is one of the trust’s clearest advantages.
Costs on Day One and Every Year After
Cost is where the two structures diverge over time.
A 1031 exchange requires a qualified intermediary to hold the sale proceeds. You can’t touch the money during the exchange; constructive receipt kills the deferral.1Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Intermediary fees for a standard exchange typically run $800 to $1,800 as a flat charge. Qualified intermediaries are not federally regulated, so vet them carefully. Once the exchange closes, the cost is done.
A deferred sales trust requires an independent third-party trustee with no family or business relationship to the seller. That independence is not optional; if the IRS decides the seller kept direct or indirect control over the proceeds, installment treatment is denied and the full gain becomes taxable in the year of sale. Trustee fees typically run 0.5 to 1.5 percent of assets under management annually. On a $5 million transaction, that’s $25,000 to $75,000 every year the trust operates, which compounds meaningfully across a multi-decade deferral. Add a tax attorney to draft the trust and a CPA who understands installment reporting, and the setup cost climbs before the first payment goes out.
The Interest Charge on Large Installment Sales
Section 453A imposes a special interest charge on large installment obligations that many deferred sales trust promoters gloss over.
If the sales price exceeds $150,000 and your outstanding installment obligations from the year’s sales exceed $5 million at year-end, you owe annual interest on the deferred tax liability tied to the portion above $5 million.6Office of the Law Revision Counsel. 26 USC 453A – Special Rules for Nondealers The charge is calculated using the IRS underpayment rate, which has run in the 7 to 8 percent range in recent years. In effect, the government charges you interest on the tax you’re deferring.
A 1031 exchange has no comparable charge because there’s no installment obligation. On transactions well above $5 million, run the math carefully. The annual interest charge, combined with trustee fees and investment management costs, can exceed what you’d pay by simply recognizing the gain and investing the after-tax proceeds. Deferral only pays off if the trust’s returns beat the combined drag.
What Happens When You Die
This is the comparison point that tends to settle the question for long-term holders.
If you die owning real estate, including property acquired through one or a chain of 1031 exchanges, your heirs receive a stepped-up basis equal to the property’s fair market value at the date of death.7Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent Every dollar of deferred gain from every prior exchange disappears. Your heirs can sell immediately with little or no capital gains tax due. That’s what makes the “swap till you drop” strategy one of the most powerful wealth-transfer tools in the code.
An installment note held at death gets the opposite treatment. Under Section 691, the remaining unreported gain is “income in respect of a decedent,” and your estate or heirs recognize that income as payments continue.8Office of the Law Revision Counsel. 26 USC 691 – Recipients of Income in Respect of Decedents No step-up. The deferred tax bill passes to the next generation along with the note. If your primary goal is moving wealth to heirs with minimal tax friction, the 1031 exchange is clearly the better tool.
The IRS Risk Sitting Under Deferred Sales Trusts
This is the piece that rarely appears in marketing decks and matters most.
The IRS has taken an increasingly hard line on monetized installment sale transactions, a broader category that captures many deferred sales trust structures. In a 2021 analysis, the agency called the theory behind these arrangements “flawed” and identified several doctrines it could use to challenge them, including economic benefit, constructive receipt, and the pledging rules under Section 453A(d).
In 2023, Treasury published proposed regulations that would classify monetized installment sale transactions as “listed transactions,” the most serious category of reportable tax shelter.9Federal Register. Identification of Monetized Installment Sale Transactions as Listed Transactions A listed transaction designation requires participants and advisors to disclose the arrangement to the IRS, and failure to disclose carries steep penalties. The IRS has also placed monetized installment sales on its annual “Dirty Dozen” list of abusive schemes.
Not every deferred sales trust is a monetized installment sale. The line the IRS is drawing turns on whether the seller effectively gets immediate access to the proceeds, typically through a loan secured by the note or trust assets, while still claiming deferral. Arrangements that reach that line are squarely in the agency’s sights. A trust where the seller genuinely waits for scheduled payments without borrowing against the note stands on firmer ground, but there is no published IRS ruling or Tax Court decision blessing the deferred sales trust structure by name.
Related-party rules under Section 453(e) create a further trap. If the trust is treated as related to the seller and it resells the property to an end buyer within two years, the gain can be pulled back to the seller immediately.2Office of the Law Revision Counsel. 26 USC 453 – Installment Method That’s why trustee independence gets so much attention.
By contrast, the 1031 exchange has been litigated for a century, refined by decades of IRS guidance, and upheld consistently. The rules are strict and unforgiving on deadlines, but they’re well understood. Legal risk on a properly executed 1031 exchange is close to zero. Legal risk on a deferred sales trust is real and unresolved. If you’re seriously considering one, pay for an independent tax opinion from an attorney who did not structure the trust, and factor the cost of a potential IRS challenge into your financial analysis.
How to Choose
If you’re selling investment real estate and plan to buy more investment real estate, the 1031 exchange is almost always the right tool. It’s cheaper, the rules are settled, and holding until death wipes out the deferred gain for your heirs.
If you’re selling a business, a professional practice, artwork, a partnership interest, or a primary residence with gain above the Section 121 limits, a 1031 exchange isn’t available to you. The installment approach may be the only deferral option, and a properly structured deferred sales trust can work, provided you use an independent trustee, avoid any borrowing against the note, get an independent tax opinion, and price in the annual trustee fees, the Section 453A interest charge if applicable, and the loss of a step-up at death.
If you’re a real estate investor who wants to diversify out of real estate entirely, neither strategy is perfect. The 1031 exchange won’t let you leave the asset class. The deferred sales trust will, but at meaningful cost and with unsettled legal risk. That trade-off is the honest heart of the choice.
