This bill aims to amend the Internal Revenue Code of 1986 by significantly increasing the earned income tax credit (EITC) for parents with young children. The legislation specifically targets families with qualifying children who have not yet attained age four, enhancing the financial support available to them. For eligible individuals with one qualifying child under four, the credit percentage will increase by 42.24 percentage points . For those with two or more qualifying children under four, the credit percentage will increase by 30.07 percentage points for each of the youngest three children. The bill also adjusts the phaseout percentage, increasing it by 5 percentage points for each of the youngest three qualifying children under age four. A key provision allows the Secretary to establish a program enabling taxpayers to elect to receive any additional refund payments resulting from these increases in equal monthly increments . These amendments are set to apply to taxable years beginning after December 31, 2025, providing enhanced tax relief to working parents with young children.
