Learn how to leverage mortgage interest and property tax deductions to reduce your tax burden
Homeownership comes with significant financial benefits, particularly when it comes to tax time. Understanding how to maximize your mortgage-related tax deductions can save you thousands of dollars each year.

Understanding Mortgage Tax Deductions
What Are Mortgage Tax Deductions?
Mortgage tax deductions allow homeowners to reduce their taxable income by deducting mortgage interest and property taxes paid throughout the year. These deductions can significantly lower your overall tax burden, making homeownership more affordable.
The two primary mortgage-related deductions are:
- Mortgage Interest Deduction: Interest paid on up to $750,000 of mortgage debt
- Property Tax Deduction: Part of the State and Local Tax (SALT) deduction, capped at $10,000

Pro Tip: Standard Deduction vs. Itemizing
You only benefit from mortgage deductions if your total itemized deductions exceed the standard deduction. For 2023, the standard deduction is $13,850 for singles and $27,700 for married couples filing jointly. Our calculator automatically compares these amounts to determine if itemizing makes sense for you.
Understanding Tax Reform Changes
The Tax Cuts and Jobs Act of 2017 significantly changed mortgage-related deductions:
| Deduction Type | Before 2018 | After 2017 |
|---|---|---|
| Mortgage Interest Limit | $1,000,000 | $750,000 ($375,000 if married filing separately) |
| SALT Deduction Cap | Unlimited | $10,000 ($5,000 if married filing separately) |
| Standard Deduction | $6,350 single / $12,700 married | $13,850 single / $27,700 married |
| Home Equity Loan Interest | Deductible for any purpose | Only deductible if used for home improvements |
Important Considerations
Due to the higher standard deduction and SALT cap, fewer homeowners now benefit from itemizing deductions. Our calculator helps determine if itemizing makes financial sense for your specific situation.
Maximizing Your Mortgage Tax Benefits
Strategic Timing of Home Purchases
Consider these timing strategies to maximize your tax benefits:
- Make your January mortgage payment in December to accelerate the interest deduction
- Pay property taxes before year-end if you're close to itemizing threshold
- Consider making charitable contributions in the same year as large mortgage interest payments
Understanding the "Bunching" Strategy
Tax bunching involves concentrating deductible expenses into alternating years to exceed the standard deduction threshold:
- In Year 1: Make extra mortgage payments, pay property taxes early, make larger charitable contributions
- In Year 2: Take the standard deduction, defer some deductible expenses to Year 3
- This strategy can maximize deductions over a two-year period
When Itemizing Makes Sense
- Your mortgage interest + property taxes > standard deduction
- You have significant other deductions (charitable, medical)
- You're in a high tax bracket
- You live in a high-property-tax state
When Standard Deduction Is Better
- Your total deductions < standard deduction
- You have a small mortgage or low interest rate
- You're in a lower tax bracket
- You live in a low-tax state
Beyond the First Year: Long-Term Tax Planning
Your mortgage tax benefits change over time as you pay down your loan:
Early Years: Maximum Benefits
In the first years of your mortgage, most of your payment goes toward interest, maximizing your deductible amount. This is when tax benefits are highest.
Middle Years: Declining Benefits
As you pay down principal, the interest portion of your payment decreases, reducing your deductible amount each year.
Later Years: Minimal Benefits
Toward the end of your mortgage, most payments go toward principal, with little interest to deduct. You may no longer benefit from itemizing.
Planning for the Future
Use our calculator's year-by-year projections to understand how your tax benefits will decline over time. This can help with long-term financial planning and decision-making about refinancing or selling your home.
Special Considerations
Home Equity Loans and HELOCs
Under current tax law, interest on home equity debt is only deductible if the funds are used to "buy, build, or substantially improve" your home. Our calculator doesn't include these deductions by default but allows you to add them as "other deductions" if applicable.
Rental Properties
Mortgage interest on rental properties is deductible as a business expense, not as an itemized deduction. Different rules apply, and our calculator focuses on primary residence deductions.
Points and Closing Costs
Points paid to secure your mortgage may be deductible in the year paid, depending on specific IRS rules. Our calculator focuses on ongoing interest and property tax deductions.

Frequently Asked Questions
Can I still deduct mortgage interest if I take the standard deduction?
No, mortgage interest is an itemized deduction, so you must forgo the standard deduction to claim it. This is why many homeowners no longer benefit from the mortgage interest deduction after tax reform.
What if my mortgage is more than $750,000?
You can only deduct interest on the first $750,000 of mortgage debt ($375,000 if married filing separately). Interest on amounts above this limit is not deductible.
Are second homes eligible for the mortgage interest deduction?
Yes, but the $750,000 limit applies to the combined debt on your primary and secondary residences.
How does refinancing affect my deductions?
When you refinance, the new loan is subject to the same $750,000 limit. Points paid on a refinance are generally deducted over the life of the loan rather than in the first year.
What documentation do I need for these deductions?
Your mortgage lender will send you Form 1098 each year showing the interest you paid. Keep records of property tax payments and consult with a tax professional for specific documentation requirements.
