You must have a filing status other than married filing separately. You must be U.S. citizen or resident alien all year, or a nonresident alien married to a U.S. citizen or resident alien and filing a joint return.

You must not be a qualifying child of another person . You must have a qualifying child who meets the age, relationship, residency, and joint return tests, and is not treated as the qualifying child of another person. If you do not have a qualifying child, you must be of age 25 but under 65 at the end of the year and not qualify as a dependent of another person, and live in the United States for more than half of the year. If you qualify for the credit, the amount of your EITC will depend on your filing status, whether you have a qualifying child, and if so, how many, and the amount of your wages and income last year.
