Couple sells home for $890,000, faces $328,000 taxable gain

A couple who bought their home for $62,000 in 1984 has sold it for $890,000, but the financial implications of that sale are significant. The couple can exclude up to $500,000 of capital gains under IRS Section 121, leaving them with a taxable gain of approximately $328,000 after the exclusion. This taxable amount will impact their adjusted gross income (AGI), which plays a crucial role in determining their Medicare costs two years after the sale closes in 2026.

The timing of this sale highlights a long-standing issue with capital gains tax exclusions, particularly the Section 121 ceiling, which has not adjusted for inflation since it was set in 1997. As a result, many longtime homeowners are facing unexpected taxable gains as their properties appreciate significantly. In this case, the couple’s original home, which appreciated by over $800,000, will add $9,240 in Medicare surcharges to their expenses in 2028, further complicating their financial landscape.

The raw gain from the sale is impressive at $828,000, but the couple's situation underscores how the $250,000 and $500,000 exclusion limits, which seemed generous decades ago, now leave many homeowners vulnerable to substantial tax liabilities. Homeowners can mitigate this impact by keeping records of improvements made to their properties, which can increase their cost basis, and by carefully planning their withdrawals from retirement accounts to manage their MAGI.

As home values continue to rise, this case serves as a cautionary tale for homeowners and potential sellers. The lack of inflation adjustment for tax exclusions means that many may find themselves facing unexpected financial burdens when selling their homes. Seeking guidance from fiduciary financial advisors could help homeowners navigate these complexities and better prepare for the implications of selling their properties in today’s market.
