How Property Taxes Affect Your Mortgage (What Homeowners Need to Know)

When you calculate your monthly housing costs, the price of the home is only one part of the equation. Understanding how property taxes affect your mortgage is vital because these taxes can add hundreds of dollars to your monthly bill. In most cases, your lender collects these taxes from you every month and pays them to the local government on your behalf.

In this guide, we will break down what property taxes are, how they are calculated by your city or county, and why they often cause your mortgage payment to go up even if you have a fixed interest rate. By the end of this article, you will know exactly how to plan for these costs in 2026 and beyond.

The Role of the Escrow Account

Most homeowners don’t write a separate check to the tax office. Instead, your lender uses an Escrow Account. This is basically a holding account where a portion of your monthly mortgage payment is set aside specifically for taxes and insurance.

This is a major part of how mortgage payments are calculated. The bank takes your estimated annual property tax bill, divides it by 12, and adds that amount to your principal and interest payment. When the tax bill is due at the end of the year, the bank pays it using the funds you’ve been saving in your escrow account all year long.

Quick Tip: Your “Loan Estimate” will show you exactly how much the lender expects your monthly property tax cost to be before you even sign the closing papers.

Takeaway: Your monthly payment is actually a bundle of costs, with property taxes acting as a “savings account” managed by your bank.

Why Your Mortgage Payment Changes

It can be a shock to see your mortgage bill go up when you have a “fixed-rate” loan. This happens because property taxes are not fixed. As your home’s value increases or your local government changes its budget, your tax bill will fluctuate.

If your taxes go up, your lender will perform an “Escrow Analysis.” If they find there isn’t enough money in your account to cover the new, higher tax bill, they will increase your monthly mortgage payment to make up the difference. This is one of the most common reasons why the math behind how mortgage payments are calculated shifts over time.

Factors That Influence Your Tax Bill

  • Assessed Value: What the local tax assessor thinks your home is worth.
  • Mill Rate: The tax rate set by your local town or county.
  • Local Referendums: New taxes approved by voters for schools, parks, or emergency services.

Takeaway: Even with a stable loan, your “Total Payment” can change annually based on the tax needs of your local community.

How to Lower Your Tax Burden

While you can’t opt out of property taxes, you can take steps to ensure you aren’t overpaying. Many homeowners don’t realize they have options to lower this part of their mortgage bill.

Strategy How it Works Potential Result
Homestead Exemption A tax break for people who use the home as their primary residence. Significant annual savings.
Tax Appeal Formally challenging the assessor’s value of your home. Lower assessed value = lower taxes.
Special Exemptions Discounts for seniors, veterans, or people with disabilities. Reduced or capped tax rates.

Reducing your taxes is just as effective as learning how extra payments reduce interest when it comes to saving money. Both strategies help you keep more of your hard-earned cash.

Frequently Asked Questions (FAQ)

What is an “Escrow Shortage”?

An escrow shortage happens when your property taxes or insurance costs end up being higher than the bank predicted. To fix this, the bank will usually give you two options: pay the difference in one lump sum, or spread the shortage out over the next 12 monthly mortgage payments.

Are property taxes tax-deductible?

In many cases, yes. Under current 2026 tax laws, you can often deduct up to a certain amount of your state and local taxes (SALT) from your federal income taxes. You should consult with a tax professional to see how much of your specific property tax payment can be deducted.

Do I have to use an escrow account?

Some lenders allow you to pay your taxes and insurance yourself (called “waiving escrow”) if you have at least 20% equity in your home. However, some lenders may charge a small fee for this, and you must be disciplined enough to save the money yourself for when the big annual bills arrive.
