It depends who paid. Only the
person who actually paid the interest/property taxes can take the deduction. If you did not pay 100% of the mortgage
interest, you can not deduct 100% of the mortgage interest. If both of you paid 50%, then you would both report your respective amounts paid on your income tax returns.
