My ex doest make much, maybe 30k, at most. I make a lot more than here. Normally she claims one child and I claim the other. She is single. I am married. I am wondering if this year claiming both kids would be more beneficial for me since I know she is taking the standard deduction. My wife is also in the same situation. She has 1 kid, who is my step daughter. Her ex makes maybe 50k a year and is single. I am wondering if we should claim her daughter as well. I know our exs would have to agree to this, but if doesnt benefit them any and it does us, we could split the difference. I am not sure if I am going to itemize. I have a rental property and only paid 9900 in mortgage interest on my primary residence. Does anyone have any advice?
