I have two teenage children (one is 18, one is almost 17). They both have after school/weekend jobs. Can I still claim them on my taxes if they work? If I claim them, will they be able to file a tax return? I am a single mother and their dad does not have any sort of custody. He pays child support only sporadically. Oh yes, I also take the Earned Income Credit on my taxes. Will I be able to continue to claim EIC?
