Refundable Credits
Refundable credits on the federal 1040 may be included on IA 1040, line 31, to the extent federal income tax was paid by applying the federal refundable credits, including:
- Earned Income Tax Credit
- Additional Child Tax Credit
- Recovery Rebate Credit
- First-Time Homebuyer Credit
- Existing Homebuyer Credit
- Refundable Education Credit
- Refundable Adoption Tax Credit
Any refundable federal credits that reduce federal income tax liability are allowed as a federal tax deduction — up to the amount of the federal tax paid by the refundable credits — on the Iowa return.
In determining the order of applying the refundable federal tax credits, the federal Earned Income Tax Credit (EITC) should be applied first, followed by the Additional Child Tax Credit, and then any other refundable federal credits.
Example: The following example illustrates how a refundable federal Earned Income Tax Credit (EITC) on a timely-filed 2020 federal 1040 may affect line 31 of the 2021 Iowa return.
