The amount of the credit you can get depends on your income and family size. Families with at least one qualifying child can get thousands of dollars with their tax refund. Even workers without a qualifying child may be eligible for the EITC.
When claiming the credit on your tax return, the most important thing is to get everything right. Even basic errors can cause issues. For example, make sure you report your income correctly and that any child you claim meets all the qualifying rules.
