Quick answers

Who pays the tax bill? You do. If you have an escrow account, your mortgage servicer collects a slice each month and pays the county for you.
Why did my payment go up? Usually because your tax bill rose and your escrow account came up short.
Can I lower my bill? Sometimes. Check your assessment for mistakes, look for exemptions (like a homestead exemption), and appeal if the value looks too high.
Is it tax deductible? Property taxes can count toward the federal state and local tax (SALT) deduction if you itemize. For 2026 that cap is $40,400 for most filers, per the IRS.

Your mortgage payment has a sneaky roommate. It does not cook, it does not clean, and it shows up on your bill every single month. Its name is property tax.

Most buyers spend weeks comparing interest rates and about four minutes thinking about property taxes. That is a mistake, because in many areas the tax slice can be a big chunk of the monthly payment. Let’s pour a coffee and walk through how it all works.

What property taxes actually pay for

Property taxes are set and collected locally: by your county, city, school district and sometimes special districts. The money funds things like public schools, roads, police, fire and libraries. Your bill is roughly:

Assessed value of your home (after any exemptions) × local tax rate = your yearly tax bill

Each local government sets its own rates and rules, so two similar houses a few miles apart can have very different bills. That is why the listing price alone never tells you the full monthly cost.

How property taxes get paid through your mortgage

Most homeowners with a mortgage don’t write a check to the county. Instead, the loan comes with an escrow account. Think of it as a savings jar your servicer holds for you.

Each month you pay principal and interest plus 1/12 of your estimated yearly taxes and homeowners insurance.
The servicer keeps that money in escrow.
When the tax bill is due, the servicer pays it from the jar.

That is where the famous acronym PITI comes from: Principal, Interest, Taxes and Insurance. When you use our mortgage calculator, plug in a real tax estimate, not a guess. It changes the answer more than people expect.

Example

Say you borrow $320,000 on a 30-year fixed at 7.24% (Freddie Mac’s weekly average for Oct 29, 2026). Principal and interest come to about $2,180.79 a month.

Your yearly property tax is $4,200. That adds $350 a month to escrow. Add insurance and your real payment is well past $2,500. The tax alone is about 16% of the P&I payment.

Piece of the payment	Monthly amount (example)	Can it change?
Principal & interest (fixed rate)	$2,180.79	No, it stays the same on a fixed-rate loan
Property tax ($4,200/yr)	$350.00	Yes, when your tax bill changes
Homeowners insurance	Varies	Yes, at renewal

Assessments: where your bill really starts

Your local assessor puts a value on your home. Depending on where you live, that might happen every year or every few years. Some states also cap how fast assessed values can rise for homesteads, while others reset the value when a home sells.

That last point surprises a lot of buyers. The seller’s tax bill on the listing may be based on a value from years ago, or may include exemptions that end when they move out. Your bill could be higher after you buy. Ask your lender or the county what the tax is likely to be for you.

Escrow shortages: the “surprise, your payment went up” letter

At least once a year, your servicer reviews the escrow account. Federal rules (RESPA’s Regulation X, enforced by the CFPB) require this escrow analysis. If taxes rose, the jar may not have enough money. That gap is called a shortage.

When that happens, two things usually change:

Your monthly escrow goes up to match the new, higher tax bill.
You make up the shortage, either in one lump sum or spread out. Under Regulation X, if the shortage is at least one month’s escrow payment, the servicer can spread it over 12 months or more, but it can’t demand it all at once.

Servicers are also allowed to keep a small cushion in the account, up to one-sixth of the year’s escrow payments (about two months’ worth).

Example

Your tax bill jumps from $4,200 to $4,800. The servicer collected $350 a month, so the account is short $600.

Your new tax escrow is $4,800 ÷ 12 = $400 a month. If the $600 shortage is spread over 12 months, that adds another $50. So for the next year the tax part of your payment is about $450, up $100. Once the shortage is repaid, it drops back to about $400 (if taxes don’t rise again).

Myth buster“My rate is fixed, so my payment can never go up.” Your principal and interest are fixed. But taxes and insurance live in escrow, and those can rise. That is the most common reason a fixed-rate payment changes.

Appealing your assessment

If your home’s assessed value looks too high, you can usually appeal. The details depend on your county, but the basic steps are similar:

Check the facts first. Wrong square footage, an extra bathroom you don’t have, or a garage that isn’t there are easy wins.
Find comparable sales. Recent sales of similar homes nearby are your best evidence.
Watch the deadline. Appeal windows are often short, sometimes only weeks after the notice arrives.
Keep paying. In most places you still pay the bill while the appeal is pending.

If you win, tell your servicer. The escrow payment can be adjusted at the next review, or sooner if you ask.

Homestead exemptions and other tax breaks

Many states offer a homestead exemption for your primary home. It takes a set amount or percentage off your assessed value, which lowers your bill. Some places also have exemptions or freezes for seniors, veterans or people with disabilities.

The catch: these are rarely automatic. You usually have to apply with your county, often by a set date after you move in. Put it on your first-time home buyer checklist right next to “change the locks.”

Fun factThe word “escrow” comes from the old French word escroe, meaning a scroll or scrap of parchment. Today it means money held by a neutral third party, but it started as a piece of paper.

The federal tax side: mortgage interest and SALT

Here is the basic picture from the IRS. It only matters if you itemize deductions instead of taking the standard deduction.

State and local taxes (SALT): Property taxes, plus state income or sales tax, can be deducted up to a cap. For 2026 the IRS says the limit is $40,400 ($20,200 if married filing separately). It phases down for modified AGI above $505,000, but not below $10,000.
Mortgage interest: Interest on up to $750,000 of home loan debt ($375,000 if married filing separately) is generally deductible for loans taken out after December 15, 2017, per IRS Publication 936.

Many homeowners still find the standard deduction is bigger. A tax pro can tell you which way wins for you.

How to plan for property taxes before you buy

Look up the current tax bill on the county website, then ask what it will be after the sale.
Check your Loan Estimate: it shows estimated taxes and the escrow you’ll pay at closing.
Run your budget with a little room for tax increases using the home affordability calculator.
Apply for any homestead exemption as soon as you’re allowed to.

FAQ

Do I have to have an escrow account?

Not always. Many loans require one, especially with smaller down payments, and some government-backed loans always do. Some conventional loans let you waive escrow, sometimes for a fee. Without escrow, you pay the tax bills yourself on time.

Why did my escrow go up when my tax bill didn’t?

Homeowners insurance is also in escrow. A higher insurance premium, or a leftover shortage from last year, can push the payment up.

What happens if I get an escrow surplus?

Under Regulation X, if the surplus is $50 or more and your loan is current, the servicer generally must refund it within 30 days of the analysis. Smaller amounts can be credited to next year.

Do property taxes go down if home prices fall?

Sometimes, but slowly. It depends on when your area reassesses and on local rates. A lower value doesn’t always mean a lower bill if the tax rate goes up.

Can I deduct the escrow money I pay each month?

You deduct the property taxes actually paid to the government in that year, not the escrow deposits. Your servicer’s year-end statement (Form 1098) usually shows taxes paid.
