The 1098 form reports mortgage interest and property taxes you paid during the year to the IRS and to you. If you own a home with a mortgage, you'll receive this form from your lender by early February each year. Understanding what information appears on the form and how it connects to your tax return helps you report deductions accurately and catch errors before filing.
The articles here explain what each section of the 1098 means, why you receive multiple copies, what to do if your form arrives late or contains mistakes, and how the mortgage interest and property tax amounts relate to itemizing deductions on your tax return.
