This bill proposes significant changes to the Internal Revenue Code of 1986 by eliminating the dollar limitations on the exclusion of gain from the sale of a principal residence . Currently, Section 121(b) of the Code allows single taxpayers to exclude up to $250,000 of gain and married couples filing jointly to exclude up to $500,000 of gain from the sale of their primary home. The legislation specifically strikes the paragraphs that establish these monetary caps, effectively allowing taxpayers to exclude the entire amount of gain from such sales. It also includes conforming amendments to ensure consistency within the relevant sections of the tax code following the removal of these limits. These changes would apply to all sales and exchanges of principal residences that occur after the date the bill is enacted into law.
