Changes five numeric income breakpoint values used to compute long-term capital gains tax brackets by amending the Internal Revenue Code provision cited as 1(j)(5)(B). The replacements take effect for taxable years beginning after December 31, 2024.

The change is narrowly targeted: it only substitutes specific numeric thresholds in the capital gains bracket formula. It does not create new credits, programs, or reporting requirements, but will affect how much tax some taxpayers owe on capital gains and will require updates to tax forms, software, and IRS instructions for the affected years.
