Income tax; provide a credit for taxpayers who claim a federal income child tax credit.

Mississippi's HB 591 creates a state income tax credit for taxpayers who claim the federal child tax credit. It provides a $200 credit per child (capped at $1,000 annually) for eligible Mississippi residents who claim the federal credit on their federal return. Unused portions of the credit can be carried forward for up to five years. The bill takes effect January 1, 2026, and requires taxpayers to submit their federal return as proof.
