Deduct Mortgage Interest Costs This Tax Season

Owning and managing rental properties comes with many expenses, but fortunately, there are tax deductions available to help reduce your financial burden and mortgage debt. One of the most significant deductions for property owners is the mortgage interest deduction, which allows you to deduct the interest you pay on your rental property loan.

But what are the rules for claiming this benefit? This article will explain how the deduction works, the mortgage interest deduction limit, and how it can save you money during tax season.

What Is the Mortgage Interest Deduction?

Can landlords deduct mortgage interest? Fortunately, the answer is yes!

The mortgage interest deduction is a tax benefit that allows property owners to deduct the interest paid on loans used to buy, build, or improve rental properties. Mortgage interest is often one of the largest expenses for property owners, making this deduction especially valuable.

This deduction reduces your taxable rental income, lowering your overall tax liability. It applies to interest on loans used to acquire or maintain rental properties, helping you offset one of your most significant business expenses.

Below is an example of what kind of payments do and don’t qualify for the mortgage interest deduction:

Qualifies:

  • Interest on loans for substantial rental property improvements, such as adding a new roof or upgrading plumbing systems
  • Refinanced mortgage interest, assuming the loan is for rental property purposes

Does Not Qualify:

  • Principal payments (only interest is deductible)
  • Interest on loans for personal-use portions of the property, such as home office
  • Points paid during refinancing for non-rental-related purposes
  • Home equity loans or home equity loan interest
  • Acquisition debt

For example, if you took out a loan to buy a rental property and paid $10,000 in interest over the year, you could deduct the entire $10,000, assuming the loan is only for the rental property.

Understanding what qualifies for the mortgage interest deduction ensures you’re maximizing your tax savings while staying compliant with IRS rules.

How to Qualify for the Mortgage Interest Deduction

To qualify for the mortgage interest deduction, you must meet specific Internal Revenue Service (IRS) requirements related to the property, loan type, and use of funds.

The mortgage must be for a property used exclusively as a rental. If the property serves as both a rental and a personal residence, you can only deduct the portion of interest related to the rental use. Also, the IRS sets limits in Publication 936 on deductible mortgage interest for personal-use properties, but there is no mortgage interest deduction limit for rental properties as long as the loan is used for business purposes.

It’s important to note that you must maintain accurate records, including loan agreements, mortgage statements, and proof of payment. These documents should clearly show that the loan was used for rental property purposes.

Meeting the qualifications for the mortgage interest deduction allows you to take advantage of one of the most significant tax breaks available to property owners.

Calculating the Mortgage Interest Deduction

Calculating your deduction involves determining how much interest you’ve paid on your rental property loan during the tax year.

Below are the steps to calculate:

  1. Collect Loan Statements: Collect your monthly mortgage statements to find the total interest paid for the year.
  2. Adjust for Mixed-Use Properties: If the property is used for both personal and rental purposes, calculate the percentage of time it’s used for rental and apply that percentage to the total interest paid.
  3. Exclude Non-Deductible Portions: Remove any interest related to personal use or non-business-related expenses.

For example, if you paid $15,000 in mortgage interest for the year and 80% of the property is used for rental purposes, you can deduct $12,000 ($15,000 x 0.80).

Accurately calculating your mortgage interest deduction ensures you claim the correct amount and maximize your tax savings.

Claiming the Mortgage Interest Deduction

Claiming this home mortgage interest deduction requires reporting the expense on Schedule E (Form 1040), which is used to report rental property income and expenses. Mortgage interest is reported in the “Expenses” section of Schedule E. Enter the total amount under the line item labeled “Mortgage Interest.”

Ensure that the amount reported aligns with your mortgage interest statements and other documentation. Any discrepancies could trigger an audit, so double-check your calculations before filing. IRS Publication 527 provides in-depth instructions for reporting rental property expenses.

Filing the mortgage interest deduction correctly on Schedule E ensures your tax return is accurate and compliant with IRS regulations.

How Much Can I Save With the Mortgage Interest Deduction?

The amount you save with the mortgage interest deduction depends on two key factors: the total amount of interest paid on your rental property loan and your tax bracket. Because mortgage interest for rental properties is fully deductible, this deduction can provide substantial financial relief for property owners, especially those with high-interest loans or significant rental portfolios.

Rental property mortgage rates tend to be slightly higher than rates for primary residences, reflecting the increased risk perceived by lenders. According to Rocket Mortgage, the interest rate for an investment property typically runs at least 0.5% to 0.75% higher than what the same borrower might pay for a primary residence. While this difference may lead to higher monthly payments compared to a home loan for personal use, the interest payments made on these loans become a valuable deduction during tax season.

Let’s say you deduct $12,000 in mortgage interest and fall into the 24% tax bracket. This deduction would reduce your tax liability by $2,880 ($12,000 x 0.24).

By reducing your taxable income, the mortgage interest deduction improves your cash flow, allowing you to reinvest in your property or expand your rental portfolio.

Understanding how the mortgage interest deduction lowers your tax burden emphasizes its importance as a financial planning tool for property owners.

Leveraging Mortgage Interest Deductions for Savings
