<prompt> Human: So Im a single parent. I want to claim my married child, as he is a student and I fully supported him. I know the filing requirement for married couples is around 20k. My married childhis spouse made 13k 6.5k each. This therefore meets the joint return test for dependents since he is only filing to get a refund?1 Can I still claim my married child, even though he is claiming his own personal exemption? Or would this be incorrect and I would claim his exemption, and he wouldnt be able to claim his on his joint return?2 Would it be okay for my married child to claim himself personal exemption and also for me to claim him as a dependent? I thought the IRS doesnt allow multiple exemptions to be claimed.Just wanted to make sure I was looking at this scenario correctly.  <response>: I thought the IRS doesnt allow multiple exemptions to be claimed.Yup, it doesnt. So you can initially both claim him, but the IRS will send both of you a letter, and you will have to prove that you can claim him. There is in reality only one person who can claim him. The IRS has a nice tool to find out whether you can claim your married son, here: If it turns out that you cant claim him, then dont do it.
