A bipartisan push in Congress to double the capital gains tax exclusion on home sales is drawing serious attention from real estate professionals — and in Florida, where long-time homeowners are sitting on decades of appreciation, the implications are particularly significant.
Under current federal law, homeowners who sell their primary residence can exclude up to $250,000 in capital gains from taxable income ($500,000 for married couples filing jointly). That threshold has not been adjusted since 1997, when median home prices looked nothing like today’s market. Legislation now gaining traction on Capitol Hill would raise those figures to $500,000 for single filers and $1,000,000 for married couples — a change that, if passed, could fundamentally shift the calculus for millions of owners who currently see no advantage in selling.
Why the Current Threshold Is No Longer Functional
The 1997 exclusion limits made sense when the median US home sold for roughly $146,000. As of recent market data, the national median is hovering near $420,000 — and in markets like Miami, that figure is dramatically higher. According to recent reporting, Miami is now more expensive than New York City, with median prices in several submarkets well above $600,000. In that environment, a homeowner who purchased in Coral Gables in 2005 for $500,000 and is now looking at a $1.2 million sale faces a taxable gain that the 1997 exclusion simply cannot absorb.
The result is what many practitioners call a “lock-in effect.” Sellers who would otherwise downsize, relocate, or exit a market entirely choose to hold their properties because the tax bill on a sale is too steep to justify. That dynamic suppresses inventory, which in turn keeps prices elevated for buyers entering the market. In Florida, where retirement-age homeowners represent a substantial share of long-time property holders, the lock-in effect is especially pronounced.
What the Bill Proposes
The legislation circulating in Congress targets the two most common seller demographics: individual owners and married couples. The proposed new exclusions are straightforward:
- Single filers: exclusion increases from $250,000 to $500,000
- Married couples filing jointly: exclusion increases from $500,000 to $1,000,000
- Eligibility requirements: largely unchanged — the property must have been used as the primary residence for at least two of the five years preceding the sale
Some versions of the bill also include an inflation-indexing provision, which would tie the exclusion amount to consumer price increases going forward. That detail matters enormously. Without indexing, Congress would need to revisit the threshold again in another two or three decades, by which point the same lock-in problem would re-emerge.
The Florida-Specific Case
Florida’s property market adds several layers to this discussion. The state has no income tax, which makes federal capital gains treatment disproportionately important for Florida sellers — there is no state-level offset available. Additionally, Florida’s Homestead Exemption and Save Our Homes assessment cap have held down property tax bills for long-term homeowners, meaning many residents have been able to stay put comfortably even as values soared. When they do decide to sell, the federal capital gains hit can be substantial.
Consider a homeowner in South Florida’s Broward County who purchased a modest home in 2001 for $180,000. At current market values — median single-family prices in Broward have risen sharply over the past five years — that same property might list near $650,000. After selling costs, the gain could easily exceed $400,000, pushing a single filer $150,000 above the current exclusion limit. Under the proposed legislation, that same seller would pay nothing in federal capital gains tax on the transaction.
The inventory implications are real. As of recent market data, home sellers outnumber buyers 2 to 1 in Miami in some segments, yet overall supply in the broader Florida market remains constrained by owner reluctance to sell and absorb a large tax liability. Doubling the exclusion could move some of that reluctant inventory to market.
Realistic Obstacles
Congressional momentum does not guarantee passage. Several points of friction remain:
- Revenue scoring: The Joint Committee on Taxation will need to estimate the cost to the federal treasury over a ten-year window. A significant revenue reduction could complicate the bill’s path through budget reconciliation.
- Investor vs. primary owner distinction: Critics have raised concerns that a higher exclusion primarily benefits wealthier homeowners with large appreciated gains, rather than working-class families who need housing relief most.
- Timing: The current legislative calendar is crowded, and standalone tax provisions face stiff competition for floor time.
That said, bipartisan support is not trivial. The bill has attracted co-sponsors from both parties, reflecting shared constituent pressure from long-time homeowners in high-appreciation markets from Florida to California.
What Sellers and Buyers Should Do Right Now
Whether or not this bill becomes law, it raises a strategic question for Florida homeowners considering a sale in the next 12 to 24 months. If the legislation passes, the financial case for selling becomes meaningfully stronger for anyone sitting on substantial appreciation. If it stalls, the current exclusion limits remain in place — and the lock-in effect continues.
For buyers, the more important signal is inventory. Any legislation that incentivizes long-time owners to list could provide modest relief in markets where supply has kept prices stubbornly high, particularly in mid-tier Florida markets where first-time and move-up buyers are most active.
The practical step for sellers right now: run the numbers under both scenarios with a CPA before making any listing decision. Know exactly where your gain falls relative to the current $250,000 or $500,000 thresholds, and build a timeline that accounts for the possibility — not the certainty — that those thresholds increase. Waiting for a bill that may not pass is its own risk. Selling before it passes, only to see it enacted months later, is another. An informed position requires knowing both outcomes clearly before committing to either.
