Use Form 1098, Mortgage Interest Statement, to report mortgage interest (including points, defined later) of $600 or more you received during the year in the course of your trade or business from an individual, including a sole proprietor. Report only interest on a mortgage, defined later.
File a separate Form 1098 for each mortgage. The $600 threshold applies separately to each mortgage, so you are not required to file Form 1098 for a mortgage on which you have received less than $600 in interest, even if an individual paid you over $600 in total on multiple mortgages. You may, at your option, file Form 1098 to report mortgage interest of less than $600, but if you do, you are subject to the rules in these instructions.
If an overpayment of interest on an adjustable rate mortgage or other mortgage was made in a prior year and you refund (or credit) that overpayment, you may have to file Form 1098 to report the refund (or credit) of the overpayment. See Reimbursement of Overpaid Interest, later.
Also use Form 1098 to report MIP of $600 or more you received during the calendar year in the course of your trade or business from an individual, including a sole proprietor, but only if section 163(h)(3)(E) applies. See the instructions for Box 5, Mortgage Insurance Premiums on page 6.
