Connecticut Earned Income Tax Credit

Connecticut EITC took effect in tax year 2011 and in the following years since, hundreds of thousands of Connecticut’s working families have benefited from the credit.

The state EITC, layered on top of the federal credit, is set at 40% of the federal EITC and is limited to taxpayers with earned income under $68,675.

Eligibility for the EITC is tied both to income and household size and it’s fully refundable, so even if you owe no income tax, you can still claim the full credit amount.
