The form might look different because Box 1 Mortgage Interest Received from Payer(s)/Borrower(s) is the mortgage interest amount received from the payer of record during the tax year and includes interest and late charges. This box would not include prepaid interest or any Homeowner Assistance Funds (HAF) funds applied to interest. If the loan originated during the referenced tax year, Box 1 would include Closing Interest Paid, negative amortization (deferred interest) paid, shared appreciation amounts, default interest paid, and prepayment penalties. The IRS Form 1098, Mortgage Interest Statement, is used to report mortgage interest of $600 or more on any one mortgage during the calendar year.
