I have 2 children with my domestic partner. We both live together with the children. I make around 125,000 a year and she is around 50,000 a year. I claim head of household since I pay over 50 % of all the bills. I have claimed the children on my tax returns in the past, should I continue to claim them on this years tax filings or should she ? Wanting to know which return would be greater when it comes to the child tax credits ? We also pay around 15,000 a year in child care.
