Understanding Mortgage Interest Deductions

They’re here to encourage homeownership by allowing taxpayers to deduct interest paid on their home loans from their taxable income. Historically, this deduction has undergone several legislation changes, most notably with recent tax reforms that have adjusted the amount of deductible mortgage interest and modified the rules for home equity debt deductions.

Eligibility Criteria for Mortgage Interest Deductions
Who gets in on this benefit?
To qualify for mortgage interest deductions, homeowners must meet specific requirements. The mortgage must be secured by a primary home or a second home, and the funds obtained through the mortgage must have been used to buy, build, or substantially improve the home. Distinctions are made between primary residences and investment properties, with different rules applying to each. See our FAQs below for more details.

For mortgages taken out after December 15, 2017, the deduction is limited to the interest on the first $750,000 of mortgage debt. This change affects homeowners’ taxable income, potentially increasing their tax liability. This tax legislation still applies today.
The Impact of Refinancing on Your Deductions

Tax Strategies for Overcoming Mortgage Interest Limitations
Looking for a workaround? Interest tracing is a method that can help homeowners circumvent the limitations on deducting mortgage interest.

By tracing the interest related to the portion used for the rental property, the homeowner can deduct that interest as a rental expense, thereby maximizing their deductions.
Record-keeping and Documentation for Mortgage Interest Deductions

Homeowners should keep detailed documentation of all mortgage interest paid, as well as how loan proceeds are used, to ensure compliance with IRS requirements and to facilitate audit-proofing of interest tracing activities.

Beyond mortgage interest, homeowners can deduct other expenses related to homeownership, such as property taxes (up to a $10,000 limit) and home office expenses if they meet specific criteria. The requirements are harsh, don’t believe everything you see on social media. These deductions can complement mortgage interest deductions, further reducing taxable income.
