HB 1659, the "Promote Child Thriving Act," creates an income tax credit for married biological parents of children under 18. It provides $500 per child for those living at home with married parents, or $1,000 per child if the parents were married before the child's birth. To qualify, parents must be legally married for the entire tax year, reside with the child for at least six months (with exceptions for military deployment or newborns), and be listed as biological parents on the birth certificate. The credit cannot reduce tax liability below zero and may be carried forward for up to 10 years if unused. This policy directly affects married couples raising biological children in Oklahoma.
