If you and at least one other person (other than your spouse if you file a joint return) were liable for and paid interest on a mortgage that was for your home, and the other person received a Form 1098 showing the interest that was paid during the year, attach a statement to your return explaining this. Show how much of the interest each of you paid, and give the name and address of the person who received the form. Deduct your share of the interest on line 11 of Schedule A (Form 1040), and print "See attached" next to the line. You will need to paper file your tax return.
Similarly, if you are the payer of record on a mortgage on which there are other borrowers entitled to a deduction for the interest shown on the Form 1098 you received, deduct only your share of the interest on line 10 of Schedule A (Form 1040). You should let each of the other borrowers know what his or her share is.
