I'm trying to find out if I can claim head of Household status and claim my son as a dependant. He was 18/19 in the tax year 2010. He was in the Army for 5 months getting out at the end of May. I'm not sure how much he earned but I have a feeling that it is over the 3650 that I read about. He is not a student. He has been living with me the entire time (7 months) and not working. I have covered all of his expenses. Can I claim him if he earned under the $3650? If he did earn more than the $3650, can I file a joint return with him or can I claim his income and then take him as a qualifying child or adult? Since I’ve paid most of his expenses for the year I’d like to be able to claim him.
