Child Tax Credit for Pregnant Moms Act of 2023 This bill allows a child tax credit for an unborn child who is born alive. It also allows the credit upon certification that a mother's pregnancy resulted in a miscarriage (the involuntary death of an unborn child who was carried in the womb for less than 20 weeks) or that the child was stillborn (the involuntary death of an unborn child who was carried in the womb for 20 weeks or more).
