so back in 2016 tax return i filed and claim my son but then i found out later his father claim him as well ( we both got accepted and got refund) and didn't tell me by mistake (we are not married) i was in a different country by the time we do our tax
so in December 2017 we both received a letter that the other parent claim the same our son SSN. my question is who's have to file for amended and pay it back to IRS when doing tax this year 2017? how is it work for amended and how much to pay back ?
my son live with me most after he was born and his father was gone around 7 months and his father name is not not our son birth certificate just me
