My boyfriend and i have lived together all year. I have 2 children from a previous marriage. I receive child support from my children's father. My boyfriend pays for shelter expenses, rent, electric, water etc. Use child support for the kids clothes, school activities and expenses and various other items for the kids. My boyfriend and i had a baby together this year as well. I was high risk for pregnancy so i worked very little. My income will be less than 3,500. I also received state medical and snap assistance. Could/ should my boyfriend claim all 3 kids?
