I am California resident. Couple years ago, I gave 1/2 of down payment to my nephew who bought a house in Ohio where he lived and worked there. He is sole owner of the house, and have his name on the mortgage. Two years after, he lost his jobs. So I have given him money to pay property tax, and monthly mortgage. He added my name on the title of his house. He has little income, so he will use standard deduction for filling his tax. Could I claim those payments for deduction from federal and state income tax? If yes for federal, and no on California, how do I remove the portion of Ohio property tax and mortgage interest from federal? Thank you
