What Is the Mortgage Interest Deduction Limit?

In 2017, the Tax Cuts and Jobs Act (TCJA) made big changes to mortgage interest deduction guidelines. These changes put stricter limits on how much you can deduct.

Tax Filing StatusBefore Dec 16, 2017After Dec 15, 2017
Joint filing$1,000,000$ 750,000
Individual filing$500,000$ 375,000

How Can You Claim Mortgage Interest Deduction?

To claim the mortgage interest deduction, you need to follow the steps below:

1. Obtain Form 1098 From Your Lender

Your lender provides you with Form 1098, which reports the total mortgage interest you paid during the tax year. You’ll need this form to claim the deduction accurately.

2. Choose to Itemize Deductions

When you file your tax return, you must opt for itemizing deductions rather than taking the standard deduction. Itemizing allows you to claim specific deductions, including mortgage interest.

3. Complete Schedule A (Form 1040)

Schedule A is the tax form used to list your itemized deductions. On line 8A, you’ll enter the mortgage interest amount from your Form 1098. This will reduce your taxable income.

4. File Necessary Documents

Depending on your mortgage type, you’ll need to file different forms along with your Form 1040:

  • For mortgages on your primary residence, file Schedule A and Form 1040.
  • For a rental property, report the interest on Schedule E.
  • If it’s for a home office or business purpose, use Schedule C.

5. File Your Tax Return

After completing the required forms (Form 1040 and any additional schedules), review them for accuracy, sign them, and submit your tax return to the IRS. You can e-file or mail in your return.

    ✍️ Note: Only claim itemized deductions like mortgage interest if your total exceeds the standard deduction amount.

How to Calculate Tax Deduction on Mortgage Interest?

Let’s consider a scenario where your taxable income is $60,000. You purchased a home with a mortgage of $200,000 at an annual interest rate of 4%. Throughout the tax year, you paid $8,000 in mortgage interest.

Now, let’s see how this affects your tax return assuming a tax rate of 20%:

ScenarioWithout Mortgage Interest DeductionWith Mortgage Interest Deduction
Income$60,000$60,000
Itemized Deductions$0$8,000
Taxable Income$60,000$60,000 – $8,000 = $52,000
Estimated Tax Owed (20%)$12,000$10,400

By claiming this deduction, your taxable income is reduced by $8,000. This results in a potential tax saving of $1,600.

What Qualifies as Mortgage Interest Tax Deductible?

  1. Primary and Secondary Home Loans: You can deduct interest on loans secured by your primary residence and one additional home. This includes loans taken out to buy the house or as construction loans.
  1. Home Improvement Loans: Interest on loans used for substantial home improvements that add value to your property or prolong its life qualifies for deductions. This does not include routine maintenance.
  1. Refinanced Loans: If you refinance your mortgage, the interest on the new loan qualifies for the deduction. This applies as long as the principal does not exceed the original loan amount. Any additional amount used for home improvements also qualifies.
  1. Home Equity Loans and Lines of Credit: Interest on home equity loans or lines of credit is deductible if the loan is used to buy, build, or improve your home. 
  1. Mortgages for Rental Properties: If you have a loan on a rental property, the interest is deductible but not on your tax return. Instead, it’s reported on Schedule E (Form 1040).
  1. Mortgage Points: Prepaid interest in the form of mortgage points you have paid can be deducted, either in the year of payment or over the loan’s life.
  1. Other Deductible Interest: Several other types of interest payments can also qualify as mortgage interest deductions:
    • Late payment charges on your mortgage.
    • Prepayment penalties incurred due to early loan payoff.
    • Interest paid before selling your home (deductible for the period before the sale, even if it occurs during the year).

What Do Not Qualify as Mortgage Tax Deductibles?

Here’s a quick rundown of some common costs that don’t qualify for this deduction:
