The "More Homes on the Market Act" aims to amend the Internal Revenue Code of 1986 by substantially increasing the tax exclusion for capital gains realized from the sale of a principal residence. This legislation would double the current exclusion amounts, raising them from $250,000 to $500,000 for single filers and from $500,000 to $1,000,000 for those filing jointly. A significant new provision introduces an inflation adjustment mechanism for these increased exclusion amounts. Beginning in taxable years after 2025, the $500,000 and $1,000,000 thresholds will be indexed to the cost-of-living, ensuring their value is maintained over time. These changes would apply to all sales and exchanges occurring after the bill's enactment.
