About Connecticut Schedule CT-EITC
Connecticut Schedule CT-EITC is used by eligible full-year Connecticut residents to claim the Connecticut earned income tax credit. The schedule starts by asking whether you claimed the federal earned income credit for the same tax year, then uses the federal EIC amount to calculate the Connecticut credit.
If you were a Connecticut nonresident or part-year resident during 2025, Schedule CT-EITC says to stop because you do not qualify for the Connecticut earned income tax credit. Attach completed Schedule CT-EITC to the back of Form CT-1040 or Form CT-1040X when claiming the credit.
