1997 Home Sale Tax Exclusion Has Not Been Updated for Inflation
The $250,000 individual and $500,000 married-couple capital gains exclusion, unchanged since the Taxpayer Relief Act of 1997, has lost significant real value as home prices have risen, and...
The capital gains tax exclusion applied to home sales has remained fixed at $250,000 for individuals and $500,000 for married couples since Congress established those limits in the Taxpayer Relief Act of 1997 (Public Law 105-34). That law, signed by President Bill Clinton, has not been amended in the 29 years since its enactment, according to the congressional record.
The practical effect of the static threshold is measurable. The Bureau of Labor Statistics Consumer Price Index data shows that $250,000 in 1997 is equivalent to approximately $490,000 in 2026 dollars, meaning the real value of the exclusion has declined by roughly half over that period. Homeowners in markets where median prices have risen substantially since 1997 are more likely to exceed the nominal cap and owe capital gains tax on the portion of sale proceeds above those limits.
At least one legislative proposal has been introduced in the current Congress to index the exclusion to inflation. The precise bill number, sponsorship, and committee referral status were not confirmed in available public records as of the date of this story. The text of any such bill, if introduced, would be available through Congress.gov, and committee hearing schedules would be posted on the relevant House Ways and Means or Senate Finance Committee calendars.
Critics of the current structure argue that the unchanged thresholds create a lock-in effect, in which long-term homeowners defer selling because the taxable gain would be substantial, reducing available housing inventory. Proponents of keeping the current cap contend that indexing would reduce federal revenue and primarily benefit higher-income homeowners whose properties have appreciated the most. Neither the Congressional Budget Office nor the Joint Committee on Taxation had published a scored estimate of an inflation-indexing proposal in publicly available documents reviewed for this report.
What remains unknown is the total federal revenue impact of the unchanged exclusion relative to an indexed alternative, what specific legislation has been formally introduced, and which members have signed on as sponsors. A formal CBO or JCT score, once a bill is reported out of committee, would provide the most reliable estimate of fiscal impact. The Treasury Department's Office of Tax Analysis would hold administrative data on the number of taxpayers annually affected by the existing cap.
