Earned Income Credit - EIC

A bit of money off your taxes, if you meet a few requirements.

The EIC (also known as the Earned Income Tax Credit, or EITC) applies to people earning low to moderate incomes. It generally applies to people with children, though there are additional rules that allow some people without a qualified child to earn the credit (that grumpy 30-year-old playing Xbox in your basement probably doesn't qualify, even though he's technically your kid).
