You must be at least age 25 but under age 65 at the end of 2007. If you are married filing a joint return, either you or your spouse must be at least age 25 but under age 65 at the end of 2007. It does not matter which spouse meets the age test, as long as one of the spouses does.

If neither you nor your spouse meets the age test, you cannot claim the EITC.
