1.) Can I claim Dude even if he's over 18? Well of course (yeah you're all thinking of course Star - he's a dependent; he went to some school, and you supported him duh) but did you know that I can claim him as EARNED INCOME CREDIT this year AND LAST year? Check to see exactly what qualifies your 19-24 year old child (married or not) (EITC qualifying rules) THAT is why President Obama created these tax clinics - (thank you) Didn't know that. 2.) Can I claim DF if I file Head of Household as the state considers us "common law"? We do not consider ourselves legally married. NO. If you have questions -? Here's the link to call your local office and make an appointment for help. Don't ask me I'm confused too. I just know I felt ripped off and now I have a little hope. If the EIC is anywhere NEAR what the child tax credit is? Oh happy day. If they (COMPLETELY FREE TAX HELP if you make $49,000 OR UNDER) OR CALL YOUR LOCAL UNITED WAY. yeah - thank me later....lavish me with gifts......remember me at Christmas and in August, or when you get more money back from Uncle Sam....hahah....mwah ha ha. Good Luck Everyone.
