Filing Taxes? What do You Need To Know About Mortgage Interest Deduction?


Have you mortgaged your home and are relaxed that your mortgage payments will be deducted from your taxable income? Well, you need to think it through. Not all of your mortgage payments are tax deductible and you can only benefit from tax deductibility if you are clear about what gets subtracted to decrease your taxable income for a lower tax payment. Let’s dive in together to learn about the IRS rules and requirements that need to be met for tax deductibility benefits.

What does the Term ‘Mortgage Interest Deduction’ Refer to?

Mortgage interest is the payment you make on your home financing loan. Mortgage interest (not all) can be deducted from your taxable income to give you relief from paying a higher amount of taxes when you are already paying mortgage expenses. You can make better estimates and draw your savings.

Along with your mortgage interest, the mortgage premium and points can also be subtracted from your taxable income, provided the criteria are met. The mortgage payments that you make in a year are deducted from the taxable income of the same year, and this amount should be calculated based on the interest payment and not the principal amount of the loan. Further, the itemization of your payments is crucial for the deduction to get accepted by the authorities.

Although the mortgage interest deduction is not a new concept, the variations in rules and deductible amounts have and are continuously changing. Due to an ever-rising homeownership rate, the authorities keep on decreasing the limits of the tax-deductible amounts. It is important to keep in the loop to claim the acceptable amounts and attain the associated advantages.

What Counts as Mortgage Interest?

According to the IRS, 'mortgage interest' is the interest on a loan secured by a qualified home. This qualified home could be your primary or secondary home. The interest payments on the mortgage or home equity loan, taken to buy, develop, or improve your primary residence or second home, are tax deductible.

The home can be any type of property, like a condo, apartment, mobile home, boat, or any such vehicle. To call the place a home, the prerequisites include sleeping, cooking, and eating spaces and amenities.

Not only interest payments can be subtracted to lower your taxes, but there are other expenses as well that come under the umbrella of mortgage interest deduction. Let’s discuss those.

  • Non-rented Second Home Interest

    If you are using the property for more than 14 days or longer than 10% of the rented-out duration, you can take away that interest from your taxable income, provided you fulfill the requirements.

  • Fees for Late Payments

    If you are penalized for paying your mortgage beyond the due date, you can deduct this fee from your taxable income when computing your mortgage interest deduction.

  • Prepayment Penalties

    You can deduct the amount of any financial penalties you incur for paying off your mortgage earlier than required from your taxable income.

  • Points

    Point payments are often made by borrowers to attain a lower interest rate. If you are one of those borrowers, you can decrease your taxable income for the year by the amount of points you paid for the same filing year.

  • Home equity loans and home equity lines of credit

    If you took out either a home equity loan or home equity line of credit (HELOC) to pay for a home improvement project, you can deduct the interest on the amount you used to upgrade your property.


What Doesn’t Count as Deductible Mortgage Payments?

There are certain expenses related to homeownership that are not deductible on your tax return. For example, you cannot deduct the cost of utilities. Other expenses that are related to mortgage include:

  • Homeowners Insurance
  • Extra principal mortgage payments
  • Title insurance
  • Settlement or closing costs
  • Deposits, down payments, appraisal fees, notary fees, or earnest money that you forfeited
  • Accrued interest on a reverse mortgage
  • Mortgage insurance premiums - There are some exceptions for certain types of loans and certain income levels.
  • Accrued interest on a third or fourth home.
  • A home equity loan money/HELOC funds - The money utilized for reasons that cannot be associated with the home.

What is the Maximum Limit you can Claim as the Mortgage Interest Deduction?

The mortgage interest deduction limit is the total amount of mortgage interest that you can deduct on your tax return. The deduction limit depends on the date you took out the mortgage as well as your filing status.

Mortgages taken out after December 15, 2017, are eligible for a $750,000 deduction ($375,000 if you're married but filing separately). This means that if the mortgage debt for your primary or secondary residence is $750,000 or less, all interest paid on that debt is deductible.

For mortgages taken out prior to December 15, 2017, the deduction limit is $1 million. Therefore, you can deduct all the interest paid on any older mortgages with balances of up to $1 million.

The deduction limit applies to the total amount of mortgage debt on your primary and second homes combined. If you have more than one mortgage, you must figure out the total interest paid on all of them and the amount that falls within the permitted limit.

Who can Claim Interest Deduction?

To qualify for the mortgage interest deduction, there are certain requirements that you are required to fulfill. One such requirement is that you must be a borrower of the loan and be in charge of making payments, and hence are legally accountable for it. If you are just a co-signer on the loan but not listed as a borrower, you are not considered legally responsible for the mortgage. This in turn means that you cannot claim the deduction.

Similarly, you are responsible for paying the mortgage interest in order to qualify for the mortgage interest deduction. If the interest was paid by someone else you cannot claim the deduction, even if you are legally responsible for the mortgage.

In addition, dependency on someone else’s tax return wouldn’t qualify you to make the deduction. This is due to the fact that dependents are not regarded as being able to support themselves and thus are not eligible to claim certain deductions on their own tax returns.

What is the Method for Claiming the Deduction?

Following the proper method of claiming a deduction would improve your chances of the tax authority’s approval. Here’s a rundown for your convenience.

  • Communicate with your Lender

    Your lender is responsible for tracking the amount of interest you have paid. He will provide you with ‘Form 1098’ at the start of the calendar year. This form shows the amount of interest you paid on your mortgage loan. It may also include information about other deductible costs, such as mortgage points or fees.

  • Itemized Deductions versus the Standard Deduction

    After receiving Form 1098, you need to determine whether to itemize your deductions on your federal income tax return or opt for the standard deduction. You can compare the two options using a Schedule A form.

    You must itemize all of your deductible expenses, including your mortgage interest, property taxes, charitable contributions, and medical costs. Alternatively, the standard deduction amount is the allowed deductible amount which differs as per the taxpayer’s filing status, age, and other relevant variables.

    If your itemized deductible costs are greater than the standard deduction limit, it can be financially beneficial to itemize and claim the mortgage interest deduction. However, if your calculations show otherwise, it is better to opt for the standard deduction. The purpose is to reduce the taxable income and taxes and maximize the gains.

  • Form 1098

    If you decide to itemize your deductions, you will need to give your Form 1098 to your tax professional to report the amount of mortgage interest paid during the year. This form is necessary to accurately claim the deduction and should be included with the homeowner's tax return.
    You can also complete Schedule A on Form 1040 by yourself. You can record the reported mortgage interest in 8a, unreported interest in 8b, and insurance premiums in 8d.

In the Case of an IRS Inquiry, what Documentation will be Needed?

If you have claimed the mortgage interest deduction, the IRS can ask for proof to ensure eligibility. You may be required to provide the following documents:

  • Copies of Form 1098 - Mortgage Interest Statement
  • Closing statement - Home or refinancing
  • Information about the buyer of your home
  • Federal tax return from the previous year

Are there any Exceptions or Special Considerations for the Mortgage Interest Deduction?

Here is a comprehensive list of special considerations for the mortgage interest deduction:

  • Office Space in the Home

    If you use a part of your property for a home office, only the portion used for living qualifies for a mortgage interest deduction. You will have to calculate the square footage that is being used for residential purposes.

  • Home Under Construction

    According to the guidelines, constructing your own qualified home gives you a 24-month period for qualification.

  • Home Sales

    You can deduct interest accrued on the loan up to the date (not including that date) of sale if you sold your home last year.

  • Points for Refinancing

    If your refinancing was done in 2021, and you made points payments to decrease your interest rate, you can subtract some amount from your taxable income spread over the duration of the new loan.

  • Second Home Rentals

    You should have used your second home yourself for more than 14 days or 10% of the rented-out days.

  • Pre-settlement Payments

    You cannot deduct the payments made during the pre-settlement period when you are purchasing the home. As you are living in that house, the payment would be considered rent, even if settlement papers label them as interest, and hence is non-deductible.

  • Destructed Home

    Any unforeseen accidents, damages, or destruction of your home won’t take away your eligibility for tax deductibility. However, you need to rebuild and live in it or sell the land within a specific time.

  • Loan Proceeds for Business Purposes

    If you are utilizing the mortgage money for business purposes, and you are a sole proprietor, the interest on the loan is recorded on Schedule C. If the money is being utilized to buy a rental property, the interest would be recorded on Schedule E.

  • Rental Property Loans

    Interest paid on a loan taken against a rental property is not tax-deductible, as the collateral is not the potential home itself.

  • Loans for Tax-exempt Investments or Insurance

    You cannot deduct mortgage interest if you used a home mortgage to purchase tax-exempt securities, single-premium life insurance, or annuity contracts.

  • Co-op Apartment Ownership

    If you own a co-op apartment, you are eligible to subtract your portion of interest of the building mortgage.

  • Timeshare

    Considering other standard requirements, you can decrease your taxable income by the amount of interest you pay on the timeshare home by regarding it as a home or second home.

Listed above are only a few exceptions. There are more that may match your special circumstances. Go through Pub.936 from the IRS to find the possible exemptions.

Bottom Line

The financial benefits of claiming the mortgage interest deduction can be substantial, especially for those who have large mortgage loans. The amount of the deduction is based on the interest paid on the mortgage loan during the tax year. In general, the more interest paid, the larger the deduction.

Being a homeowner, you can either go for the standard deduction or do the itemization of your tax return. Itemization is the essential part of claiming a deduction and getting it approved. Choose whatever amount (itemization or standard deduction) is saving you better money.
