How Texas Property Taxes Affect Your Monthly Mortgage Payment

When buyers move to Houston from out of state, the sticker shock usually isn’t the home price — it’s the monthly payment. Texas property taxes are among the highest in the country, and because your lender folds them into your mortgage payment, they can add hundreds of dollars a month on top of principal and interest. The good news is that once you understand how the tax is built and how to lower it, you can budget for it accurately and avoid surprises. Here’s how Texas property taxes really work for a Houston homeowner.

The short version: Texas has no state income tax, so it leans on property taxes instead — combined rates around Houston typically run 2% to 3.5% of a home’s value. Your lender collects that in monthly installments, which is why a Houston payment can feel high even when the loan itself is modest.

Why Texas property taxes feel so high

Texas is one of a handful of states with no personal income tax. That money has to come from somewhere, and a big share of it comes from property taxes that fund your school district, county, city, and local services. There’s no single statewide rate — instead, each taxing entity sets its own and they stack on top of each other. Add them up and a typical Greater Houston bill lands somewhere between 2% and 3.5% of the home’s assessed value per year. On a $350,000 home, that’s roughly $7,000 to $12,000 a year, or about $585 to $1,000 a month — almost always collected as part of your mortgage payment.

How the tax lands in your monthly payment

If you put less than 20% down, your lender sets up an escrow account and divides your estimated annual taxes and homeowner’s insurance into twelve pieces, adding one to each monthly payment. When the tax bill comes due at the end of the year, the lender pays it out of that account on your behalf. It’s convenient, but it has two consequences worth knowing: your monthly payment is bigger than just principal and interest, and it can change from year to year as your assessed value and the local rates move. If your escrow comes up short after a tax increase, your lender will raise the monthly amount to catch up — a common reason a payment jumps in year two.

What makes up your tax rate

Your total rate is the sum of every entity that taxes your address. The big one is almost always the school district (ISD), followed by the county and, if you’re inside city limits, the city. On top of those, many newer Cypress and Katy neighborhoods sit inside a special district — most commonly a MUD (Municipal Utility District) that funds water, sewer, and drainage and levies its own tax. A MUD can add a meaningful amount to your rate, which is why two similar homes a few miles apart can carry very different bills. When you’re comparing homes, always look at the total rate for that specific address, not the headline county number. I walk through this in more detail in my guide to MUD districts and Houston property taxes.

The homestead exemption: your biggest lever

Here’s the part that saves Houston homeowners the most money. If the home is your primary residence, you can file for a homestead exemption, which removes a chunk of your home’s value from school-district taxation before the rate is applied. As of 2026, that school-district exemption is $140,000 of value, with an additional $60,000 for homeowners 65 or older or who are disabled. On top of the savings, a homestead also caps how much your taxable value can rise each year at 10%, which protects you from runaway increases when home values climb. You file once — for free — with your county appraisal district, and it stays in place until you move. In Harris County that’s the Harris County Appraisal District; the filing deadline is generally April 30. Don’t leave this on the table — it’s one of the first things I remind every buyer to do after closing.

You can challenge your appraisal

Your tax bill is driven by the value your county appraisal district assigns each year — and you have the right to protest it if you think it’s too high. Each spring you’ll receive a notice of appraised value, and there’s a window (usually until mid-May) to file a protest with evidence like comparable sales or photos of needed repairs. Plenty of homeowners do this every year and win a reduction, and you can handle it yourself or hire a protest service that works on contingency. The Texas Comptroller publishes a clear guide to the process and the exemptions you may qualify for.

How taxes shape what you can afford

Because taxes ride inside your monthly payment, they directly affect your buying power. Two homes at the same price can qualify differently depending on their tax rate, so when you’re setting a budget it pays to think in terms of the all-in monthly number — principal, interest, taxes, and insurance — rather than the price tag alone. When I help you run the numbers with a lender, we build the real Houston tax rate for each home into the estimate, so the payment you see is the payment you’ll actually have.
