What to check first (before you act)

Goal and timeline

Before you even look at your 1098, clarify your tax filing goal. Are you aiming to claim the mortgage interest deduction? Do you want to ensure you’re taking advantage of all eligible deductions? Your timeline is also crucial – tax forms are typically due by April 15th each year, so know your filing deadline.

Current cash flow

Understanding your current financial situation helps contextualize the information on Form 1098. How much disposable income do you have? Are you on track with your other financial goals? This isn’t directly related to reading the form, but it’s a good reminder that tax deductions are part of a larger financial picture.

Emergency fund or safety buffer

While not directly on Form 1098, having a solid emergency fund is paramount before making any tax-related decisions that might impact your cash on hand. Ensure you have 3-6 months of living expenses saved. This buffer provides peace of mind and prevents you from having to tap into investments or take on debt for unexpected events.

Debt and interest rates

Form 1098 focuses on mortgage interest, but it’s wise to have a general understanding of your other debts and their interest rates. High-interest debt, like credit cards, should often be prioritized over tax deductions that offer less immediate financial relief.

Credit impact

Your credit score is a critical component of your financial health, influencing everything from mortgage rates to insurance premiums. While Form 1098 itself doesn’t directly impact your credit, understanding your mortgage payments and interest helps you manage your overall credit obligations responsibly.

Step-by-step (simple workflow)

Step 1: Locate Form 1098

What to do: Find the Form 1098 you received from your mortgage lender. This is typically mailed to you in late January or early February.
What “good” looks like: You have the official document in hand, ready for review.
A common mistake and how to avoid it: Not receiving the form or receiving it late. Avoid this by checking your lender’s online portal for electronic statements or contacting them if you haven’t received it by mid-February.

Step 2: Verify Your Information

What to do: Check that your name, address, and Social Security Number (or Taxpayer Identification Number) are correct on the form.
What “good” looks like: All personal identifying information matches your records.
A common mistake and how to avoid it: Typos in your SSN or name. This can cause issues with the IRS. Double-check these details carefully before proceeding.

Step 3: Examine Box 1: Mortgage Interest Received

What to do: This box shows the total amount of mortgage interest you paid during the tax year.
What “good” looks like: The amount reported aligns with your own records of mortgage payments.
A common mistake and how to avoid it: Assuming the box is always accurate. Always compare it to your loan statements or amortization schedule.

Step 4: Review Box 2: Outstanding Mortgage Principal

What to do: This box shows the principal balance of your mortgage as of January 1 of the tax year.
What “good” looks like: This figure is generally consistent with your mortgage statements from the beginning of the year.
A common mistake and how to avoid it: Confusing principal with interest. This box is informational and not directly used for the interest deduction calculation itself.

Step 5: Check Box 3: Mortgage Origination Date

What to do: This box shows the date your mortgage was originated.
What “good” looks like: The date reflects when your current mortgage loan began.
A common mistake and how to avoid it: Mistaking this for a refinance date if you’ve refinanced. It refers to the original loan.

Step 6: Understand Box 4: Refund of Overpaid Interest

What to do: If your lender refunded you any interest you overpaid in a prior year, it will be reported here.
What “good” looks like: This box is blank, or the amount is clearly understood and accounted for.
A common mistake and how to avoid it: Not knowing what this box means. If it has a value, it might reduce the amount of interest you can deduct.

Step 7: Note Box 5: Mortgage Insurance Premiums

What to do: This box reports any mortgage insurance premiums you paid. These may be deductible under certain circumstances.
What “good” looks like: You understand if you paid mortgage insurance and if it’s potentially deductible.
A common mistake and how to avoid it: Assuming all mortgage insurance is deductible. There are income limitations and other rules that apply.

Step 8: Look at Box 6: Prepaid Interest

What to do: This box shows any prepaid interest you paid. This can include points paid to obtain a mortgage.
What “good” looks like: You understand if you paid points and how they are treated for tax purposes.
A common mistake and how to avoid it: Not understanding that points paid to buy a home are generally amortized over the life of the loan, though some may be deductible in the year paid.

Step 9: Review Box 7: Address of Property

What to do: This box shows the address of the property for which the mortgage was made.
What “good” looks like: The address is correct for your primary or secondary residence.
A common mistake and how to avoid it: This is usually straightforward, but ensure it corresponds to the property where you are claiming deductions.

Step 10: Check for Other Boxes

What to do: Some lenders may use other boxes on Form 1098 to report additional information, such as property taxes paid.
What “good” looks like: You are aware of any additional information provided and understand its relevance.
A common mistake and how to avoid it: Overlooking information in less common boxes that could be relevant to your tax situation.

Step 11: Compare to Your Records

What to do: Cross-reference the figures on Form 1098 with your own mortgage statements, payment histories, and any other relevant financial documents.
What “good” looks like: All figures match or any discrepancies are understood and can be explained.
A common mistake and how to avoid it: Relying solely on the 1098 without verification. Discrepancies can occur due to timing of payments or lender reporting errors.

Step 12: Use for Tax Filing

What to do: Use the information from Form 1098 (especially Box 1) to accurately report your mortgage interest deduction on Schedule A (Form 1040) if you itemize deductions.
What “good” looks like: You have accurately claimed all eligible deductions, potentially reducing your tax liability.
A common mistake and how to avoid it: Forgetting to claim the deduction or claiming it incorrectly. Consult tax software or a professional if unsure.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not receiving or losing Form 1098	Inability to claim the mortgage interest deduction, potential tax errors	Contact your lender immediately. Keep digital copies and organized physical files of all tax documents.
Incorrect personal information	Delays in tax processing, potential IRS notices, inability to claim deductions	Carefully review all identifying information (name, SSN, address) against official documents. Contact your lender to correct errors promptly.
Overlooking Box 5 (Mortgage Insurance Premiums)	Missing out on a potential deduction, reducing tax liability	Understand the deductibility rules for mortgage insurance premiums and check if your income qualifies. Consult a tax advisor.
Misinterpreting prepaid interest (Box 6)	Incorrectly claiming points or other prepaid interest as a deduction	Familiarize yourself with IRS rules on deducting points and prepaid interest. Generally, points are amortized.
Relying solely on Form 1098 without verification	Claiming incorrect deduction amounts, leading to underpayment or overpayment	Always cross-reference Form 1098 with your own mortgage statements and payment records.
Not itemizing deductions when eligible	Paying more tax than necessary	If your total itemized deductions (including mortgage interest) exceed the standard deduction, itemizing will likely save you money.
Incorrectly calculating the deduction	Underpaying or overpaying taxes, potential penalties and interest	Use tax software or consult a tax professional to ensure accurate calculation of your mortgage interest deduction, especially if you have complex scenarios (e.g., second homes, points).
Failing to report refunds (Box 4)	Overstating deductible interest	If you received a refund of overpaid interest, subtract it from your total deductible interest.
Not understanding the mortgage origination date	Confusion about loan terms or tax implications	This date is specific to the loan itself. It’s generally for informational purposes and not directly used in the deduction calculation.
Ignoring property taxes reported in other boxes	Missing out on potential tax deductions	Be aware that some lenders may report property taxes paid, which can also be deductible if you itemize.

Decision rules (simple if/then)

• If you paid mortgage interest during the tax year, then you likely received a Form 1098, because lenders are required to report this.
• If Box 1 of Form 1098 shows a positive amount, then you paid mortgage interest, because this is what the box represents.
• If you plan to itemize deductions on your tax return, then you should use Form 1098 to claim the mortgage interest deduction, because it substantiates your claim.
• If your total itemized deductions are less than the standard deduction, then you should take the standard deduction instead of itemizing, because it will result in a larger tax deduction.
• If Box 5 reports mortgage insurance premiums, then you may be able to deduct them, because they are sometimes deductible subject to certain income limitations.
• If you paid points to obtain your mortgage, then check Box 6 or consult your lender, because prepaid interest, including points, has specific tax treatment.
• If the information on Form 1098 does not match your records, then contact your mortgage lender, because there may be an error in reporting.
• If you have a home equity loan or line of credit, then check if the interest is reported on a separate 1098, because the deductibility rules can differ.
• If you are unsure about claiming the mortgage interest deduction, then consult a tax professional, because they can provide personalized advice based on your specific situation.
• If you used your mortgage for a second home or rental property, then consult IRS Publication 527 or a tax advisor, because the rules for deducting interest can be different.
• If you paid off your mortgage during the year, then your Form 1098 will reflect the interest paid up to the payoff date, because it reports interest received for the entire tax year.
• If you refinanced your mortgage, then you may receive a 1098 from the new lender for the period under that loan and potentially a final statement from the old lender, because each lender reports only the interest they received.

FAQ

What is Form 1098?

Form 1098 is an informational tax form that a mortgage lender sends to a borrower and the IRS. It reports the amount of mortgage interest and, in some cases, points and other amounts paid by the borrower during the tax year.

Do I have to file Form 1098?

You do not file Form 1098 yourself. Your mortgage lender files it with the IRS and sends you a copy. You use the information from Form 1098 to complete your tax return.

When will I receive Form 1098?

Lenders are generally required to send Form 1098 to borrowers by January 31st of the year following the tax year. For example, you would receive your 2023 Form 1098 by January 31, 2024.

Can I claim the mortgage interest deduction if I don’t itemize?

No, the mortgage interest deduction is an itemized deduction. If you take the standard deduction, you cannot deduct mortgage interest. You should only itemize if your total itemized deductions exceed the standard deduction amount for your filing status.

What if my Form 1098 is incorrect?

If you believe the information on your Form 1098 is incorrect, you should contact your mortgage lender immediately. They can issue a corrected form if necessary. You should also keep your own records of payments to support your tax filing.

Does Form 1098 include property taxes?

Sometimes. While Box 1 is for mortgage interest, some lenders may use other boxes or provide separate statements to report property taxes paid through an escrow account. Check your Form 1098 carefully for any additional reported amounts.

What are “points” on Form 1098?

Points are fees paid directly to a lender at closing in exchange for a lower interest rate. If reported in Box 6, they are considered prepaid interest and may be deductible in the year paid or amortized over the life of the loan, depending on specific rules.

Can I deduct interest on a home equity loan?

Interest on a home equity loan or home equity line of credit (HELOC) may be deductible if the loan proceeds were used to buy, build, or substantially improve your home that secures the loan. Consult IRS Publication 936 or a tax professional for details.
