Generally your lender will provide a
Form 1098 to report mortgage amounts you paid to them. These amounts could include interest, points, or mortgage insurance premiums (PMI).
If you paid your lender less than $600, your lender might not send you a
Form 1098.
You may also not get a
Form 1098 if you paid mortgage interest directly to the person who sold you your home instead of a bank or other lender. This is called a seller-financed mortgage.
In either case, the mortgage interest you paid may still be deductible. You can enter it as an other homeowner expense.
