Form 1098 is an information statement reporting mortgage interest and specified loan data; it supports but does not determine a borrower's deduction.
IRS Form 1098, Mortgage Interest Statement, is an information return generally filed by a lender, servicer, governmental unit, or other business recipient that receives at least $600 of mortgage interest from an individual on one mortgage during the calendar year. The payer or borrower receives a copy to help reconcile mortgage-interest and related tax records.
Form 1098 does not itself create a tax deduction. It can report interest on any obligation secured by real property, while the borrower’s deduction depends on separate rules involving debt purpose, property use, loan dates, debt limits, itemizing, and other facts.
$600 threshold is an information-reporting rule applied separately to each mortgage; it is not a minimum deduction amount.A person engaged in a trade or business generally files Form 1098 when, in that business, the person receives $600 or more of mortgage interest during the year from an individual, including a sole proprietor, on one mortgage. Financial institutions, mortgage servicers, governmental units, and some other businesses can be filers.
The reporting threshold applies mortgage by mortgage. A recipient may voluntarily file for a lower amount, while exceptions can apply based on who paid the interest and whether receipt occurred in a trade or business.
For Form 1098 reporting, a mortgage is generally an obligation secured by real property. That reporting definition is broader than the tax rules for a personal home-mortgage-interest deduction.
| Box | What it generally reports | Review point |
|---|---|---|
| 1 | Mortgage interest received from the payer or borrower | Reconcile to statements and payment records; do not assume full deductibility |
| 2 | Outstanding mortgage principal at the required measurement date | This is not necessarily year-end principal or the deductible debt limit |
| 3 | Mortgage origination date | Helps identify the loan vintage but not every refinancing or acquisition fact |
| 4 | Refund or credit of prior-year overpaid interest | May require a tax-benefit or income review if the interest was previously deducted |
| 5 | Mortgage insurance premiums received when reportable | Reporting does not establish a current deduction |
| 6 | Reportable points paid on purchase of a principal residence | Points can require separate eligibility and timing analysis |
| 7 | Indicates when the securing property’s address matches the borrower’s address | A checked box does not establish principal-residence tax treatment |
| 8 | Address or description of the property securing the mortgage | Reconcile when several properties or loans are involved |
| 9 | Number of properties securing the mortgage | Multiple collateral properties can complicate allocation |
| 10 | Other information | Review the issuer’s label and supporting records |
| 11 | Mortgage acquisition date when the reporting recipient acquired the mortgage | Different from the original mortgage date in box 3 |
The form revision and box instructions can change. Use the form and instructions for the reporting year rather than relying on an old statement’s layout.
The amount in box 1 can differ from deductible home mortgage interest for several reasons:
Conversely, a taxpayer can have potentially deductible interest that does not appear on Form 1098, such as qualifying interest below the reporting threshold or interest paid to a mortgage holder not required to file. The taxpayer still needs adequate records and must meet the substantive deduction rules.
A homeowner refinances in July and receives two Forms 1098:
| Statement | Selected reported amount |
|---|---|
| Former servicer, box 1 interest | $6,800 |
| Former servicer, box 4 refund of prior-year interest | $200 |
| New lender, box 1 interest | $7,400 |
| New lender, box 6 points | $2,000 |
Adding the two box 1 amounts gives $14,200 of reported current-year interest, but that is only the start of the review. The borrower should:
$200 refund has a current tax consequence based on prior treatmentThe example does not conclude that $14,200 plus $2,000 is deductible. It shows how Form 1098 feeds a documented tax analysis rather than replacing it.
A taxpayer with a Mortgage Credit Certificate may use Form 1098 interest as one input to Form 8396. The Form 1098 amount may still need to be allocated if the MCC’s certified indebtedness is smaller than the mortgage.
The MCC credit and mortgage-interest deduction also must be coordinated. Form 1098 does not perform that adjustment and does not show how much credit the taxpayer can use.
More than one recipient may report interest for different portions of the year. Compare issuer names, account numbers, dates, and monthly records to ensure amounts are complete and not duplicated.
The old and new loans can produce separate forms. Interest, points, principal, and dates should be tied to the correct loan, and an MCC requires a separate reissuance analysis.
The form may name one payer even when several people are liable or make payments. The tax result depends on ownership, liability, payment, filing status, and other facts, not merely whose taxpayer identification number appears first.
A seller or other mortgage holder may not be required to issue Form 1098 when interest is not received in a trade or business. The borrower should retain the note, security instrument, payment evidence, and identifying information required by applicable return instructions.
A corrected statement should be reconciled to the original and to the lender’s explanation. Do not add original and corrected amounts together.
