How to Calculate Mortgage Interest Deduction Over $750,000

Calculating mortgage interest deduction over $750,000 can be a complex task for many homeowners. With the Tax Cuts and Jobs Act of 2017, the deduction for mortgage interest has been limited to loans of $750,000 or less for newly purchased homes. However, homeowners who already have loans in excess of this amount can still deduct interest on their existing loans. In this article, we will guide you through the process of calculating your mortgage interest deduction over $750,000 and help you understand the necessary steps to ensure you maximize your deduction.

Understanding the Basics

Before diving into the calculation, it’s important to understand the basics of mortgage interest deduction. This deduction allows homeowners to reduce their taxable income by the amount of interest they pay on their mortgage loans. However, there are certain criteria that must be met to qualify for this deduction:

1. The mortgage must be used to buy, build, or substantially improve a primary or secondary home.
2. The mortgage must be secured by the home.
3. The interest must be paid to a lender during the tax year.

Calculating the Deduction

To calculate your mortgage interest deduction over $750,000, follow these steps:

1. Gather all necessary documents: Collect your mortgage statements, property tax bills, and any other relevant financial information.

2. Identify eligible loans: Determine which loans are eligible for the deduction. If you have multiple mortgages, identify the ones that are secured by your primary or secondary home.

3. Calculate the interest paid: For each eligible loan, calculate the total interest paid during the tax year. This information can typically be found on your mortgage statements.

4. Apply the $750,000 limit: If the total interest paid exceeds $750,000, you can only deduct interest up to this limit. For example, if you paid $1 million in interest, you can only deduct $750,000.

5. Combine interest from multiple loans: If you have multiple eligible loans, combine the interest paid on each loan to determine your total deduction.

6. Determine your taxable income: Subtract the total mortgage interest deduction from your taxable income. This will reduce your taxable income and potentially lower your tax liability.

Reporting the Deduction

To report your mortgage interest deduction over $750,000, follow these guidelines:

1. Use Form 1098: Your lender will send you Form 1098, which shows the total interest you paid during the tax year. Keep this form for your records.

2. Fill out Schedule A: Complete Schedule A (Form 1040) to report your mortgage interest deduction. Enter the total interest paid on eligible loans up to $750,000.

3. Attach the forms: Attach Form 1098 and Schedule A to your tax return.

By following these steps, you can accurately calculate your mortgage interest deduction over $750,000 and take advantage of this valuable tax benefit. However, it’s always a good idea to consult with a tax professional to ensure you are maximizing your deductions and complying with all tax regulations.
