My aunt doesn't know computers that well, so I am posting here for her, hope that is okay! We are from Michigan if that matters. My aunt has two kids with her ex husband. One is 5 and one is 2. She has physical custody and they share joint legal. When tax time came around she filed and claimed them as she has the past 5 years. A few months ago her ex husband ended up filing his and she got some of his back support is how she knew he had finally got his payment. But she found out from his sister that he also had filed and claimed their kids. It is not in the order who can claim them, but they are on the schedule of every other weekend so she has them more and we know according to law she is to claim them because of having them more, not him. Whoever he had do his taxes got him the money from them too. He went off and bought a truck and took his new wife on vacation. Now the IRS sent him something about paying the money back. She wanted to know if since he did all this is it going to affect her future IRS claims and what will happen to her ex? Will they take all of his money including support if it doesn't get paid back? Thank you so much in advance!
