This bill establishes a child tax credit for resident individual taxpayers in Kansas, effective for tax year 2025 and subsequent years. The credit amount varies based on the taxpayer's adjusted gross income, with a maximum credit of $600 for those earning up to $25,000, decreasing incrementally to $25 for those earning over $350,000. Married individuals filing separately can claim half the credit amount they would have received if filing jointly. Additionally, the bill mandates that all income thresholds and credit amounts will be adjusted annually based on the cost-of-living adjustments as determined by federal guidelines.

The legislation also outlines the criteria for a "qualifying child," which includes age, residency, support, and filing status requirements. It stipulates that if the credit exceeds the taxpayer's income tax liability, the excess will be refunded. Furthermore, the Secretary of Revenue is tasked with compiling an annual report on the child tax credit, detailing the number of recipients, adjusted amounts, and overall effectiveness of the credit, which must be submitted to relevant legislative committees by January 31 each year.
