The Earned Income Credit (EIC), also known as the Earned Income Tax Credit (EITC), is a valuable tax benefit for people who work and earn a low to moderate income. It helps reduce the amount of tax you owe and can even give you a refund even if you don’t owe any taxes.
To qualify, you must have earned income from a job or self-employment, meet yearly income limits, have a valid Social Security number, and not be claimed as someone else’s dependent.
The amount you can receive depends on your income, filing status, and whether you have qualifying children (though people without children may still qualify). Because many people are eligible and don’t realize it, it’s always worth checking each year. You must file a tax return to claim the credit, as it may result in hundreds or even thousands of dollars back.
