my daughter was 17 at the end of 2008. she made appx $4,000 from a part time job. She is supported totally by my wife and I. I am filing married joint, with a total income of $21,000. Can I claim my daughter as a dependent for earned income credit and child tax credit. I was told by a friend that because she made more than $3,500 I could not claim her. I have never heard of this. Thanks for any help !
