The Earned Income Tax Credit (EITC) is one of the most valuable tax credits for working people with low to moderate income. It's a refundable credit, meaning if it exceeds what you owe, you get the difference as a refund. The credit amount depends on your income, filing status, and number of qualifying children. For 2024, the maximum credit is over $7,830 for families with three or more children. Many eligible taxpayers miss this credit — check every year if you qualify.
