If you’re a homeowner or planning to become one, it’s essential to get familiar with the 1098 form. Whether you’re looking to claim mortgage interest deductions or just curious about how taxes work, this guide will break down everything you need to know about the 1098 form and how it can help you save money on your taxes. The process may seem overwhelming at first, but by the end of this article, you’ll be confident in your understanding of this important tax document.


What Is Form 1098?


The 1098 form, also known as the Mortgage Interest Statement, is a tax form that lenders use to report how much mortgage interest you’ve paid over the course of the year. If you’ve paid $600 or more in mortgage interest, you’ll receive a 1098 form from your lender, which you can use to calculate your deductions on your annual tax return.


The form is not just for mortgage interest—it can also include information on points paid, mortgage insurance premiums, and overpaid interest. Understanding how to properly use this form can make a significant difference when you file your taxes, especially if you’re itemizing deductions. Let's dive deeper into how it works.


Who Receives Form 1098?


If you have a mortgage and paid more than $600 in interest during the tax year, your lender is legally required to send you a 1098 form mortgage interest statement. This document will typically arrive by January 31st of the following year. Most homeowners with qualified mortgages will receive one, as it is the primary tool for documenting interest paid on homes.


However, there are situations where a lender may not send the form. For instance, if your interest paid is less than $600, or if you are paying interest to a private lender, you might not receive a form. Even in these cases, you could still deduct the interest—you just need to track it on your own and report it correctly.



What Information Does Form 1098 Include?


The 1098 form contains several key pieces of information that you’ll need to report on your tax return. Here’s a quick breakdown of what each box on the form represents:


Box 1: Interest Paid

This is perhaps the most crucial box on the form. It shows the total interest you’ve paid to your lender over the course of the year. This amount is typically deductible and is reported on your Schedule A if you’re itemizing your deductions.


Box 2: Outstanding Mortgage Principal

This box shows the total amount of principal still owed on your mortgage. While it’s not directly related to your deduction, it’s important to keep track of this as it shows how much you still owe on your home.


Box 3: Mortgage Origination Date

The origination date of your mortgage is the date your mortgage was issued. This is particularly important if you’ve refinanced or taken out a new loan within the year.


Box 4: Refund of Overpaid Interest

If you’ve overpaid your mortgage interest, this box will show the amount you’ve been refunded. This can affect the total deductible amount of interest for the year, so it’s essential to factor it into your calculations.


Box 5: Mortgage Insurance Premiums

Mortgage insurance premiums can also be deductible under certain conditions. If you have private mortgage insurance (PMI), this box will display the total amount paid, which you can then report on your tax return.


Box 6: Points Paid

If you paid points to lower your mortgage’s interest rate, this box will show the total amount paid. Points are generally deductible, but they may need to be spread out over the life of the loan rather than deducted all at once.


How to Use Form 1098 for Tax Deductions


Now that you understand what’s on the 1098 form, let’s talk about how to actually use it to your advantage. Most homeowners will use the information on this form to deduct mortgage interest on their federal tax return. However, to claim this deduction, you need to be itemizing deductions on Schedule A.


Deducting Mortgage Interest on Schedule A

The most straightforward way to use the 1098 for mortgage interest is by entering the amounts from Box 1 on Schedule A of your Form 1040. This will reduce your taxable income, potentially saving you thousands of dollars depending on your tax bracket. If you paid points or mortgage insurance premiums, those amounts may also be deductible.


Points and Insurance Premiums Deductions

If you paid points (prepaid interest), these may be deductible as well, but they’re often amortized over the life of the loan. If the points are for a mortgage on your primary residence, you might be able to deduct them fully in the year they were paid.

Mortgage insurance premiums can also be deducted, but there are income limits. If your adjusted gross income is too high, you may not qualify for this deduction.


Form 1098 for Rental Properties


Things get a little trickier when it comes to rental properties. If you have a rental property, you’ll need to report your mortgage interest on Schedule E instead of Schedule A. This is because the interest on a rental property is considered a business expense.


Schedule E: Reporting Rental Property Deductions

On Schedule E, you’ll report the interest paid on your rental property mortgage, along with other rental-related expenses. This will help reduce your taxable rental income, just like you would reduce your personal income with deductions on Schedule A. However, points paid on a rental property mortgage must be amortized over the life of the loan.


Deducting Mortgage Interest for Vacation Homes


If you own a vacation home, the process for claiming mortgage interest deductions is slightly different. If you don’t rent out your vacation home, you can deduct mortgage interest on Schedule A just like your primary residence.


However, if you rent out your vacation home for more than 14 days, you’ll need to split the mortgage interest between personal use and rental use. For the portion of time it was rented out, you’ll report that interest on Schedule E.


Additional 1098 Forms You Should Know About


While most homeowners are familiar with the 1098 form mortgage interest statement, there are other versions of the 1098 form that cover different types of tax deductions.

Form 1098-E: Student Loan Interest


If you’ve paid $600 or more in student loan interest, you’ll receive a Form 1098-E from your lender. This interest can be deducted as an adjustment to income, even if you don’t itemize.

Form 1098-T: Tuition Payments


The 1098-T is issued by educational institutions to report tuition payments. You can use this form to claim the American Opportunity Credit or the Lifetime Learning Credit.

Form 1098-C: Vehicle Donations


If you’ve donated a car, boat, or airplane to a charity, you’ll receive a 1098-C. This form helps you claim a tax deduction for your charitable donation.


Requirements for Claiming Mortgage Interest Deductions


Not everyone can claim a mortgage interest deduction. To qualify, you must meet certain criteria set by the IRS.


Eligibility Criteria

To deduct mortgage interest, you must be the primary borrower on the loan and actively making payments. The mortgage must also be secured by your home, which can be a house, condo, mobile home, or even a boat with living facilities.


Loan Amount Limits

The mortgage interest deduction is limited to interest paid on the first $750,000 of mortgage debt (or $375,000 if filing separately). If your mortgage originated before December 16, 2017, the limit is $1 million.



Common Errors to Avoid When Filing Form 1098


Filing taxes can be stressful, and mistakes happen. However, there are a few common errors to avoid when dealing with your 1098 form.


Misreporting Interest

Make sure the amount of interest you report matches what’s on Box 1 of your 1098 form. Misreporting this can trigger an audit or delay your refund.


Forgetting to Include Points

Many taxpayers forget to include points paid on their mortgage. Make sure to check Box 6 and deduct any eligible points on your tax return.


Failing to Itemize Deductions

You can only deduct mortgage interest if you’re itemizing deductions. If your total itemized deductions don’t exceed the standard deduction, you might not benefit from itemizing.



When You Might Not Receive Form 1098


In some situations, you might not receive a 1098 form even if you paid interest on a mortgage. This typically happens if you paid less than $600 in interest or if you’re paying interest to a private lender.


Even without the form, you can still deduct mortgage interest—you’ll just need to keep accurate records of your payments.


1099 INT vs 1098


The 1099 form for mortgage interest (specifically the 1099-INT) is used for reporting interest earned, whereas the 1098 is used to report interest paid. For example, if you have a savings account, the bank will issue a 1099-INT to report the interest you’ve earned on that account. On the other hand, the 1098 reports the interest you’ve paid to your mortgage lender.


Conclusion

Understanding how to use the 1098 form is essential for homeowners looking to maximize their tax savings. This form allows you to deduct mortgage interest, which can significantly reduce your taxable income, provided you meet the eligibility requirements and choose to itemize your deductions. Whether you’re a homeowner, landlord, or own a vacation property, the 1098 form mortgage interest statement is a valuable tool for reducing your overall tax burden.
