How Your Mortgage Impacts Your Taxes: What Homeowners Should Know
Yes
The Connection Between Your Mortgage and Your Taxes
Your mortgage may affect your taxes in several key ways, including:
- Mortgage interest deductions
- Property tax deductions
- Points paid at closing
- Home equity loan interest (in some cases)
However, not every homeowner benefits equally. Whether your mortgage lowers your tax bill depends on your loan details, filing status, and whether you itemize deductions.
1. Mortgage Interest Deduction
One of the most well-known tax benefits of homeownership is the mortgage interest deduction.
How it works
If you itemize deductions, you may be able to deduct interest paid on:
- A primary residence
- A second home (in some cases)
For most homeowners, interest is deductible on mortgage balances up to $750,000 (or $375,000 if married filing separately), depending on when the loan was originated.
Why it matters
In the early years of your mortgage, a larger portion of your monthly payment goes toward interest—meaning this deduction may be more valuable at the beginning of your loan term.
2. Property Taxes and Your Mortgage
Your mortgage payment often includes property taxes, which may also be deductible if you itemize.
What to know:
- State and local tax (SALT) deductions—including property taxes—are capped at $40,000 (temporary expanded cap through 2029, subject to income limits)
- Property taxes must be based on the assessed value of your home
Even though your lender may collect these taxes through escrow, they are still considered taxes you paid for deduction purposes.
3. Points Paid at Closing
If you paid mortgage points to lower your interest rate, you may be able to deduct them.
- Points paid on a purchase may be deductible in the year you bought the home
- Points paid during refinancing are usually deducted over the life of the loan
Your closing disclosure will show whether points were paid.
4. Home Equity Loans and HELOCs
Interest on home equity loans or HELOCs may be deductible—but only if the funds were used to:
- Buy
- Build
- Substantially improve your home
Interest used for credit cards, vacations, or other personal expenses is not deductible.
5. Standard Deduction vs. Itemizing
Many homeowners assume they’ll automatically get a tax break—but that’s not always the case.
When itemizing makes sense:
You may benefit from mortgage-related deductions if:
- Your mortgage interest + property taxes + other deductions exceed the standard deduction
- You live in a higher-cost or higher-tax area
- You recently purchased a home and pay higher interest
If your total deductions don’t exceed the standard deduction, your mortgage may not change your tax bill—but it still provides long-term financial value through home equity.
6. Refinancing and Taxes
Refinancing your mortgage can impact your taxes in a few ways:
- Lower interest may reduce future deductions
- Points paid during refinance are typically deducted over time
- Cash-out refinancing may affect interest deductibility if funds aren’t used for home improvements
Before refinancing, it’s smart to consider both monthly savings and tax implications.
7. Selling Your Home and Capital Gains
While this article focuses on mortgages, it’s worth noting:
Many homeowners can exclude up to $250,000 in capital gains ($500,000 for married couples) when selling a primary residence, if ownership and residency requirements are met
This is another important tax benefit tied to homeownership.
Common Tax Mistakes Homeowners Make
- Assuming mortgage interest is always deductible
- Forgetting to track property taxes paid through escrow
- Overlooking points paid at closing
- Not reviewing refinancing tax implications
- Failing to consult a tax professional when circumstances change
