For nearly three decades, U.S. tax law surrounding the sale of primary residences has remained unchanged. Since 1997, homeowners have been able to exclude up to $250,000 in capital gains for individuals and $500,000 for married couples when selling their homes. At the time, those numbers seemed more than sufficient.
But today, with home prices up more than 260% since 1997, that threshold is leaving millions of sellers exposed to what many experts call a “hidden home equity tax.” In fact:
- 1 in 3 sellers today risks paying capital gains tax on their home sale.
- By 2030, more than half of all homeowners are projected to face this tax exposure.
- Retirees and longtime owners are hit hardest, often facing five-figure tax bills on gains inflated by decades of appreciation and inflation.
For homeowners who have lived in their properties for 20–30 years, this can feel less like a windfall and more like a penalty for staying put. And with housing inventory already tight, the tax code may be discouraging many older homeowners from selling—locking up much-needed homes for younger buyers.
Why This Matters for Homeowners
Capital gains are calculated as the difference between what you paid for your home (plus improvements) and what you sell it for. But here’s the problem: the IRS hasn’t adjusted the exclusion amounts for inflation.
Imagine a retiree who purchased a home in the 1990s for $150,000. That same home might now sell for $650,000. Even after accounting for the $500,000 exclusion (if married), the sellers may owe capital gains tax on the remaining $150,000—much of which is simply due to inflation, not true wealth gain.
According to research from the University of Illinois Chicago, seniors face an average federal tax bill of $41,232 when selling a home. That’s a major disincentive for empty nesters or retirees considering downsizing.
The 3 Proposals to Fix the Home Equity Tax
Lawmakers and policy groups are recognizing the strain this outdated rule puts on American homeowners. Here are the three main proposals under debate:
-
No Tax on Home Sales Act
Introduced by Rep. Marjorie Taylor Greene (R-GA) and supported in concept by President Donald Trump, this bold plan would eliminate capital gains taxes entirely for primary residence sales.
-
- ✅ Pros:
- Removes financial penalties for selling a home.
- Could encourage more older homeowners to downsize, freeing up housing inventory.
- Backed by the National Association of Realtors® (NAR), which argues homeowners shouldn’t be taxed like investors.
- ❌ Cons:
- Benefits wealthier households in high-cost markets the most.
- Would cost the government an estimated $6 billion annually in lost revenue.
-
More Homes on the Market Act
A bipartisan bill introduced by Rep. Jimmy Panetta (D-CA) and Rep. Mike Kelly (R-PA) that would:
-
- Double the exemption to $500,000 (single) / $1 million (married).
- Index the exclusion to inflation, ensuring it keeps pace with rising home values.
- ✅ Pros:
- Protects middle-class homeowners.
- Provides immediate relief without fully eliminating revenue.
- Could help increase housing supply by reducing tax-driven hesitation to sell.
- ❌ Cons:
- Doesn’t eliminate tax liability entirely for higher-cost areas.
- Still leaves some long-term owners facing exposure if home appreciation exceeds the new caps.
-
Indexing Capital Gains for Inflation
Backed by groups like the National Taxpayers Union Foundation and Cato Institute , this more technical fix would adjust the home’s cost basis for inflation.
That means instead of taxing the entire difference between purchase and sale price, the IRS would account for inflation and only tax the real appreciation.
-
- ✅ Pros:
- Most accurate reflection of actual profit.
- Prevents homeowners from paying taxes on “phantom gains” caused by inflation.
- Fairer across income levels.
- ❌ Cons:
- More complex for homeowners and the IRS to calculate.
- Provides less short-term inventory boost than eliminating the tax.
What’s at Stake for the Housing Market
Each proposal balances fairness, affordability, and housing supply differently:
- Eliminating the tax: Best short-term fix for freeing up homes, but costly in terms of government revenue.
- Raising and indexing caps: Politically feasible middle ground, giving relief to millions while maintaining some revenue.
- Indexing for inflation: Most targeted and fair, but less likely to deliver big increases in housing supply.
What’s clear is that doing nothing isn’t sustainable. Without reform, more homeowners will face unexpected tax bills, further discouraging mobility and keeping inventory tight in a market already struggling with affordability.
What Homeowners Should Do Now
If you’re thinking about selling, it’s important to:
- Know your numbers – work with a tax professional to estimate potential liability.
- Track home improvements – keeping receipts for upgrades can increase your cost basis and reduce taxable gains.
- Stay informed – these proposals could directly impact your equity strategy in the coming years.
Your home is likely your biggest wealth-building asset, and the way it’s taxed at sale can significantly affect your financial planning.
