The Earned Income Tax Credit (EITC or EIC) is a benefit for working people with low to moderate income. To qualify, you must meet certain requirements and file a tax return. The Earned Income Tax Credit reduces the amount of tax you owe and may give you a refund. If we determine you qualify for the Earned Income Credit, we automatically select and add this credit for you. If you qualify but have no qualifying children, you must answer a quick question about how long you have lived in the United States to determine eligibility.
