Form 1098, also known as the Mortgage Interest Statement, is an IRS form used by lenders to report the amount of interest and related expenses you paid on your mortgage during the year. If you paid $600 or more in interest on a home loan, your bank or mortgage company will send you this form so you can potentially claim a tax deduction.
1. Meaning of “Form 1098”
In plain English, Form 1098 is a “receipt” for your mortgage expenses. Most people know that owning a home comes with tax perks. The biggest perk is often the ability to deduct the interest you pay on your loan from your taxable income.
Because the IRS wants proof of how much you actually paid, they require your lender to summarize your interest, points paid at closing, and mortgage insurance premiums on this form. It’s the official paper trail that turns your monthly house payments into a potential tax break.
2. Why “Form 1098” Matters
You should care about Form 1098 because it can significantly lower your tax bill if you “itemize” your deductions. Mortgage interest is one of the largest deductions available to individual homeowners.
Without this form, you wouldn’t have the official figures needed to fill out Schedule A of your tax return. Since the IRS receives a copy of your 1098 directly from your lender, having the form ensures your numbers match what the government has on file, preventing processing delays or audits.
3. How “Form 1098” Works
Lenders are required to send out Form 1098 by January 31st if you paid at least $600 in interest. If you paid less than that, you might not get a form, but you can usually find the total on your final year-end mortgage statement.
- Box 1: Shows the total mortgage interest you paid during the year.
- Box 2: Shows the outstanding principal balance on your mortgage as of January 1st.
- Box 6: Shows “Points” paid on the purchase of your principal residence, which are often deductible in the year you bought the home.
To benefit from the form, the total of your itemized deductions (like mortgage interest, charity, and state taxes) must be higher than the Standard Deduction for your filing status.
4. Simple Example of “Form 1098”
Imagine Mike and Jenny bought a house a few years ago. In 2025, they paid $12,000 in mortgage interest. In January 2026, their bank sends them a Form 1098 showing that $12,000 in Box 1.
When they file their taxes, they see that the Standard Deduction for a married couple is $30,000 (verify exact limits for the current tax year). Because their total itemized deductions (including the $12,000 interest) only add up to $25,000, they choose the Standard Deduction instead. Even though they didn’t “use” the 1098 to deduct the interest, the form was essential for them to do the math and see which option saved them more money.
5. Who Is Affected by “Form 1098”?
This form is a staple for anyone who borrows money to own property, including:
- Homeowners: Individuals with a primary or secondary residence.
- Investors: People with mortgages on second homes (though rental property interest is handled differently on Schedule E).
- Landlords: Who may receive 1098s for business-related properties.
- Co-op and Condo Owners: Who pay a share of the building’s mortgage interest.
6. Common Mistakes Related to “Form 1098”
- Assuming it’s always deductible: There are limits on how much mortgage debt is eligible for the interest deduction (currently up to $750,000 for most homeowners). If your loan is larger, you can’t deduct the full amount in Box 1.
- Missing the “Points”: If you bought a home or refinanced, check Box 6. People often forget to deduct the points they paid at closing, which can be a huge tax saver.
- Confusing it with property taxes: While some 1098s show property taxes paid through an escrow account (usually in Box 10), others don’t. Don’t assume the 1098 is your only record for property tax deductions.
- Not checking for a digital copy: Many modern banks no longer mail paper forms. You may need to log into your online mortgage portal to download your 1098.

10. FAQs About “Form 1098”
What if my 1098 is missing?
Contact your lender immediately or check your online account. If your mortgage was sold to a different bank during the year, you might actually receive two different 1098s—one from each bank.
Can I deduct interest on a second home?
Yes, usually. The IRS allows you to deduct interest on a second home, provided the combined debt of both homes doesn’t exceed the total debt limit for the current tax year.
Does Box 1 include my principal payments?
No. Box 1 only includes the interest you paid. Paying down the principal is great for your net worth, but it is not a tax-deductible expense.
What are “Points” in Box 6?
Points are prepaid interest you pay at closing to get a lower interest rate. Depending on the type of loan, these can often be deducted entirely in the year you paid them.
11. Final Takeaway
Form 1098 is one of the few tax forms that represents a “win” for your wallet. While it reminds you of the interest you paid your bank, it also provides the legal proof you need to claim one of the most valuable deductions in the U.S. tax code. By keeping this form handy and comparing your itemized totals to the standard deduction, you can ensure you’re making the smartest move for your tax return and your home investment.
