This bill proposes a temporary amendment to the Internal Revenue Code of 1986, significantly increasing the capital gains exclusion for certain seniors selling their principal residence. This special provision applies to sales or exchanges occurring between January 1, 2027, and December 31, 2030 . Under this amendment, the exclusion amount for unmarried qualifying seniors would rise from $250,000 to $1,000,000 , and for married couples filing jointly, it would increase from $500,000 to $1,000,000 . Married individuals filing separately would see their exclusion increase to $500,000. To be considered a "qualifying senior," an individual must be at least 65 years old on the date of sale. Additionally, the property must be a "qualifying residence," defined as a principal residence owned by the taxpayer for a minimum of 25 years.
