The 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 includes provisions for annual adjustments to the credit amounts based on cost-of-living increases and stipulates that if the credit exceeds the taxpayer's tax liability, the excess will be refunded.

The bill also defines a "qualifying child" and outlines the criteria for claiming the credit, including age, residency, and support requirements. Furthermore, the Secretary of Revenue is tasked with compiling an annual report on the child tax credit, detailing the number of recipients, adjusted income thresholds, aggregate credit amounts, and an analysis of the credit's effectiveness. The provisions of this section are supplemental to the existing Kansas income tax act, and the act will take effect upon publication in the statute book.
