The only state that has something similar to a tax credit for pregnant women is Georgia. Georgia offers a Dependent Personal Exemption for Unborn Children.
Here is how to claim the exemption:
- Navigate to State Taxes > Your State Return > Georgia > Continue
- When you get to the screen "Here's the income that Georgia handles differently", scroll to the last section, "Miscellaneous", choose start or edit "Dependent Personal Exemption for Unborn Children"
- Enter the number of unborn children
