Line 11

If you paid home mortgage interest to a recipient who did not provide you with a federal Form 1098, report your deductible mortgage interest on line 11.

Seller-financed mortgage: If you paid home mortgage interest to the person who sold you the home and that person did not provide you with a federal Form 1098, write that person’s name, identifying number, and address on the lines next to line 11. If the recipient of your home mortgage payments is an individual, the identifying number is the recipient’s Social Security number (SSN). Otherwise, it is the employer identification number (EIN). You must also provide your SSN to the recipient.

Interest reported on someone else’s federal Form 1098: If you and at least one other person (other than your spouse, if filing jointly) were liable for and paid interest on the mortgage, and the home mortgage interest paid was reported on the other person’s federal Form 1098, identify the name and address of the person or persons who received a federal Form 1098 reporting the interest you paid.
