Section 1031 has survived every major tax reform since 1921, protected by broad support from real estate, farming, and small business constituencies, and past proposals to cap or eliminate it have failed. As of March 2026, no active legislation threatens 1031 exchanges, though tax policy is always subject to change.
A century of durability
Section 1031 became law in 1921, tucked into that year's Revenue Act. The logic was straightforward: when an investor swaps one property for another of like kind - broadly, one investment property for a similar one - they haven't really cashed out. The investment is simply continuing in a new form. Tax the swap, the thinking went, and you penalize investors for moving capital around within the same asset class.
That logic has held for more than a century, across Republican and Democratic administrations, through the Great Depression, World War II, several recessions, and every major rewrite of the tax code.
Two moments show how sturdy it is. The 1986 Tax Reform Act, the most sweeping overhaul in modern memory, wiped out a long list of tax shelters and preferences; Section 1031 came through untouched. The 2017 Tax Cuts and Jobs Act (TCJA) did narrow it, limiting exchanges to real property so that equipment, vehicles, and other personal property no longer qualify - but real estate exchanges were explicitly preserved after intense lobbying from the real estate and agricultural sectors.
Recent attempts to change it
The most serious recent push came under the Biden administration. The initial Build Back Better framework proposed capping 1031 deferral at $500,000 per taxpayer per year, with gains above that line taxed right away. The cap was estimated to raise $1.95 billion over ten years - a modest figure next to the $4-7 billion the provision defers in a single year.
It never reached a floor vote. Opposition from real estate industry groups, farm organizations, and real estate caucuses in both parties kept it out of the final bill.
That pattern repeats. Both parties periodically float 1031 changes as "pay-fors" in budget proposals - revenue used to offset spending elsewhere. These are usually opening bids, and they tend to get traded away before a deal is signed.
The case for and against
Both sides of this argument have a real case.
Supporters of preserving 1031 point to:
- Capital that gets redeployed and property that gets improved rather than sat on
- An estimated 568,000 jobs a year, according to the National Association of Realtors (NAR)
- A user base that reaches well beyond the wealthy, into middle-income investors, farmers, and small businesses
- Economic activity that generates its own tax revenue through transfer taxes, agent commissions, and construction
- A hundred years of well-understood rules
- The risk that removing it would thin out transaction volume and drag on property values
Those who want to modify or scrap it point to:
- The $4-7 billion in tax revenue deferred every year
- The way deferral can turn into permanent avoidance when paired with stepped-up basis at death, where heirs inherit at current market value and the deferred gain simply disappears
- Benefits that flow disproportionately to those who already hold the most real estate
- Complexity that creates compliance costs and room for abuse
- Capital locked into real estate by tax friction that might work harder elsewhere
The political reality sits on top of the policy debate. The coalition defending Section 1031 - the National Association of Realtors, the American Farm Bureau Federation, the National Federation of Independent Business, commercial real estate organizations, and 1031 industry groups - has been remarkably good at keeping it on the books.
Where things stand in 2026
As of March 2026, the ground is quiet:
- No active legislation targets Section 1031 for real property. NAR's legislative tracker lists "None at this time" for current bills or regulations touching 1031 exchanges.
- NAR's July 2025 analysis of the enacted tax bill confirmed it added no new limits on 1031 exchanges.
- The TCJA's real-property-only limit stays in place.
- Stepped-up basis at death, the mechanism that makes 1031 deferral potentially permanent, also stays in place.
- No significant committee hearings or markups on 1031 are scheduled.
The environment is stable, for now. Broader tax reform can surface quickly, though, especially if deficit pressure, revenue needs, or the political balance shift.
Planning when the rules could change
Some investors hold off on an exchange, waiting for the law to feel permanent. That permanence never arrives. Every tax provision is subject to change, so waiting for a guarantee is waiting forever.
If 1031 were capped or eliminated, other tools exist for deferring or spreading a gain: installment sales, which stretch a gain across years as payments arrive; opportunity zones; and charitable remainder trusts (CRTs). Knowing how they work is the difference between a policy change that forces a scramble and one that is simply another decision.
Early warning tends to come from the trade groups that follow this closely - the FEA, NAR, and the IRC 1031 Coalition among them - which track legislative activity and publish updates.
There is a temptation to build elaborate structures to guard against changes that may never come. The cost of that insurance is real and paid now: fees, rigidity, compliance overhead, all set against a law that exists only in speculation.
And when tax law does change, it usually arrives with transition rules that protect deals already underway or recently closed. Retroactive changes are rare.
Section 1031 has proven remarkably durable, defended by a broad, bipartisan coalition. No tax provision is guaranteed forever, but as of early 2026 the political ground under real property exchanges looks stable.
Frequently asked questions
Could Congress eliminate 1031 exchanges retroactively?
Extremely unlikely. Retroactive tax changes are rare, legally fraught, and politically unpopular. Any change to 1031 would almost certainly apply going forward, with transition rules for exchanges already underway.
Would a cap on 1031 exchanges affect most investors?
The Biden-era proposal set a $500,000 annual cap. Against typical exchange sizes of $500,000 to $1 million, that would reach many investors but not all - those with smaller gains could still defer fully under such a cap.
What happened when personal property was removed from 1031 in 2017?
The TCJA limited 1031 to real property starting January 1, 2018. Exchanges of equipment, vehicles, aircraft, and other personal property no longer qualify. The change applied going forward, so exchanges completed before 2018 were untouched.
