Proposals to limit or eliminate 1031 exchanges appear regularly, but none has passed since the provision began in 1921, in part because real estate and agricultural groups organize to defend it. The most recent serious effort would have capped deferral at $500,000 per taxpayer, and it did not pass. Current law is unchanged.
Last updated: March 2026
The 1031 exchange has been part of the federal tax code since 1921. Nearly every recent administration has proposed narrowing or ending it, and none of those proposals has become law. The gap between how often 1031 gets threatened and how rarely anything changes is most of the story.
The legislative record
1921 to 2016: over nine decades of stability
Section 1031 was enacted in the Revenue Act of 1921. For the next 96 years it covered both real property and personal property - equipment, vehicles, artwork, and other tangible assets. Proposals surfaced from time to time, but no law materially changed the provision.
2017: the Tax Cuts and Jobs Act
The biggest change in the provision's history came with the Tax Cuts and Jobs Act, signed in December 2017. Congress limited 1031 exchanges to real property, ending the ability to swap personal property such as equipment, aircraft, and collectibles. That was a real narrowing.
Real estate exchanges, the most common and economically significant use of 1031, came through intact. For real property investors, the core benefit was untouched.
2021: the Biden administration's proposal
The most serious recent effort to limit real estate exchanges appeared in the Biden administration's budget proposals for fiscal years 2022 and 2023. The idea: cap the gain that could be deferred through a 1031 exchange at $500,000 per taxpayer per year, indexed for inflation, and tax anything above that in the year of the sale.
Versions of the cap were folded into the Build Back Better Act and later reconciliation bills across 2021 and 2022. None passed. The proposal stalled against opposition from real estate and agricultural groups and from members of both parties representing districts with large real estate and farming constituencies.
2023 to 2025: budget proposals without traction
Later administration budgets kept referencing 1031 limits in one form or another. A budget proposal is a statement of priorities, not a law. None of these reached a vote, and no bill limiting real estate exchanges gathered enough support to reach the floor of either chamber.
March 2026: current status
As of this writing, no active legislation would change Section 1031 for real estate. The current Congress has not advanced a reform proposal. The law still stands as the 2017 amendments left it.
Why 1031 has survived
Two forces have carried the provision through decades of reform attempts: research documenting what it does for the economy, and constituencies organized to defend it.
The economic research
Studies from the National Association of Realtors, academic institutions, and the Federation of Exchange Accommodators have documented the activity that 1031 exchanges generate. Their findings, as reported by those groups:
- Exchanges raise transaction volume by letting investors reinvest instead of cashing out.
- Each exchange produces transfer taxes, recording fees, and transaction-related work.
- Removing 1031 would reduce investment activity, which could weigh on property values and cut tax revenue from other sources.
- Agricultural producers use 1031 to consolidate and diversify land, so restricting it would fall hardest on rural areas.
These arguments give cover to members of Congress who might otherwise back reform as a way to raise revenue.
Industry advocacy
The real estate industry - brokers, developers, investors, title companies, qualified intermediaries, and the professionals around them - has organized to protect 1031, and agricultural groups have done the same. These constituencies fund campaigns, keep ties with members of Congress, and mobilize fast when a proposal appears.
Credible research plus organized advocacy has made 1031 hard to kill. Reform is always possible in theory; the political cost of elimination is high.
What a realistic reform could look like
If Congress did pass reform, the likelier shape is a limit rather than an end to the provision.
An annual deferral cap. The Biden-era $500,000-per-taxpayer cap is the template. It would leave small and mid-sized investors free to exchange while limiting the benefit on large deals, and it is the version that has come closest to passing.
An income-based phaseout. Reform could tie eligibility to income, for instance allowing exchanges only below a set adjusted gross income.
A property-value threshold. Reform could apply only above a certain price, for instance denying deferral on gains from properties sold for more than $5 million.
Full elimination. This is the least likely path. The research, the range of affected constituencies, and the politics all make an outright repeal much harder than a cap or phaseout.
A prospective effective date. Almost any reform would apply going forward. Completed exchanges would not be reopened, and exchanges already in progress, where the old property has sold, would likely be grandfathered. New rules would govern transactions from the effective date onward.
Where reform risk fits into a decision
Current law is the settled fact
The 1031 exchange is law today, and has been for over a century. Building a decision around what Congress might do, when no bill exists, is speculation rather than planning. An exchange that makes economic sense under current law stands on its own terms; one that doesn't isn't rescued by the deferral. The tax rule informs the investment analysis rather than replacing it.
Fear cuts both ways
Worry about losing the benefit has pushed some investors into weak replacement properties: overpaying to close inside the 180-day window, taking properties with poor fundamentals because they were available fast, or accepting Delaware Statutory Trusts (which let investors hold a fractional interest in larger properties) with unfavorable fees out of urgency. A tax deferral does not offset a replacement property that underperforms.
The mirror-image mistake is skipping an exchange that otherwise makes sense out of fear that reform might undo it. Reform risk has been present for decades. Investors who waited for certainty missed years of tax-deferred compounding in the meantime.
Records protect a completed exchange
If reform arrives with a prospective effective date, the documentation showing an exchange closed before that date is what protects the deferral. That paper trail includes the qualified intermediary agreement, the 45-day identification letter, the closing statements, and the exchange agreement. Those records function as insurance against a future cutoff.
A worked example: how a prospective cap would apply
Suppose Congress enacted a $500,000 annual deferral cap effective January 1, 2027.
Say you complete a 1031 exchange on November 15, 2026, deferring $1.2 million in gains, with the replacement property closing on December 10, 2026. That exchange finished under current law, with no cap, so the full $1.2 million deferral holds. Only exchanges beginning on or after January 1, 2027, would face the cap.
Now suppose you planned two exchanges in 2027. The first defers $400,000, within the cap. The second involves $300,000 in gains, which pushes you $200,000 over the annual limit, and you owe tax on that $200,000 in the year of the sale.
The example shows why documentation matters: proof that an exchange closed before the effective date is what establishes grandfathered status.
What to monitor
Headlines like "1031 Exchange May Be Eliminated" draw attention but rarely match the legislative reality. What matters is what Congress introduces and what committees advance. The specific triggers worth watching, the reasons for informed consultation with a tax advisor rather than panic:
- A bill specifically addressing Section 1031, with named sponsors from both parties or from majority leadership.
- A committee markup or hearing on a tax bill that includes 1031 provisions.
- A reconciliation bill with 1031 limits among its revenue-raising measures. Reconciliation is the likeliest vehicle because it needs only a simple Senate majority.
- An effective date in proposed legislation, which sets the timeline for planning.
Until one of these happens, reform is a possibility rather than a probability. If a bill with genuine support reaches committee markup, that is when timing and strategy become worth discussing with a tax advisor.
For how 1031 works under current law, see 1031 exchange rules. To run the numbers on a specific exchange, use the calculator or talk to an advisor.
As of March 2026, no bill would change Section 1031 for real estate, and reform has been proposed for decades without passing. Any reform that did pass would almost certainly apply going forward, leaving completed exchanges intact. Those are the facts; what to make of them is the reader's call.
Frequently asked questions
Did anyone actually pass a law limiting 1031 exchanges recently?
No. Limits have shown up in budget proposals from several administrations, but none became law. The most recent serious proposal, in 2021, would have capped deferral at $500,000 per taxpayer, and it did not pass.
Why does 1031 keep surviving reform attempts?
Real estate, agriculture, and related sectors have long-standing, organized advocacy. Studies from those industries and from academic researchers report that 1031 activity supports real estate investment and generates tax revenue through transaction taxes and broader economic effects.
What would happen to my current exchanges if 1031 were eliminated?
Most likely nothing. Reform would almost certainly apply going forward: completed exchanges would not be reopened, and exchanges already inside the 180-day window would likely be protected. New rules would govern future exchanges only.
Should I rush to do a 1031 exchange before it might get eliminated?
There is no bill to rush ahead of. An exchange that makes economic sense today stands on its own terms, and a tax deferral does not turn a weak deal into a good one. Reform risk has been present for decades, so the timing question is an investment question first.
What would realistically replace 1031 if it were eliminated?
If reform passed, the likelier outcome is a cap on deferral, for example $500,000 per taxpayer per year, rather than full elimination. A complete repeal is considered unlikely given the economic impact and the organized advocacy.
