Many Texas buyers are surprised by how much property taxes shape their monthly housing cost. The tax bill does not come from your lender, nor is it set by your loan. It comes from local governments, and it follows its own calendar. This guide explains how that bill is created and how it ends up inside your monthly mortgage payment.
For a broader look at budgeting, including insurance, mortgage insurance, and the debt-to-income ratio, see our guide on how much of a house you can afford in Texas. This article goes deeper on property taxes.
Where your tax bill comes from
Three steps decide what you owe:
- Your county appraisal district sets a value. It appraises property as of January 1 each year. It does not set tax rates.
- Exemptions reduce the taxable value. The most common for owner-occupants is the residence homestead exemption.
- Each local taxing unit applies its own rate. School districts, counties, cities, and special districts each set a rate, usually expressed per $100 of taxable value, and the bill adds them together.
In simple terms: taxable value times each unit’s rate, added up. Because the units differ by address, a home in one neighborhood can have a very different bill than a similar home a few miles away.
How tax rates are set
Texas has a “truth-in-taxation” process. After the appraisal roll is certified, most taxing units calculate a no-new-revenue rate (a comparison rate that would raise the same taxes as last year on the same properties) and a voter-approval rate (the highest rate generally allowed without an election). Units usually adopt their rates in late summer or early fall, and bills typically go out around October 1.
How property taxes get into your monthly payment
Escrow: the monthly set-aside
Most Texas tax bills arrive once a year and are generally due by January 31. To avoid one large bill, many lenders collect a portion of your annual taxes each month in an escrow account, along with homeowners insurance. Your servicer then pays the bills when they come due. The CFPB explains that many lenders require escrow and that, because taxes and insurance can change from year to year, your total monthly payment may change as well.
That is why a payment that looks steady at closing can move later. If a home’s value rises, an exemption changes, or a taxing unit adjusts its rate, your escrow portion may be adjusted.
If you do not have escrow
Some loans do not use escrow. In that case, you pay the tax bill yourself. Penalties and interest generally begin February 1 on unpaid bills, and the CFPB warns that unpaid taxes can lead to fines, a tax lien, or even foreclosure. Even if escrow is optional for your loan, consider asking about it so you can budget in smaller monthly amounts.
Taxes at closing
In a typical Texas resale contract, current-year property taxes are prorated between buyer and seller through the closing date, and the parties adjust if the actual bill differs from the estimate. Your lender may also require you to fund the initial escrow account at closing. Ask your loan officer to explain these line items on your closing documents.
The homestead exemption: apply for it
If you will live in the home as your primary residence, you may qualify for a residence homestead exemption, which lowers the value used to calculate certain taxes. Our affordability guide covers the basics. A few practical points:
- You apply with the appraisal district in the county where the home is located, not with the state. The form is Form 50-114.
- The general filing deadline is April 30 of the tax year, and late applications may be allowed for a limited time.
- If you buy after January 1, the Comptroller says you may be eligible for the exemption for the applicable portion of the year, provided the prior owner did not receive the same exemption for that year.
- Once granted, you generally do not need to reapply every year unless the appraisal district asks, and you must notify it when you no longer qualify.
Do not assume a seller’s exemption carries over. Ask your agent and title company to check it early.
Reading your appraisal notice and protesting a value
Every year the appraisal district may mail a notice of appraised value. For a homestead whose value has increased, the Comptroller says notices are due by April 1, and for other property, by May 1 or as soon as practical afterward. If you disagree with the value, you have the right to protest to your county’s appraisal review board (ARB).
- The usual deadline is May 15 or 30 days after the notice is mailed, whichever is later.
- The notice explains how to file and how to request an informal meeting with the appraisal district before a formal hearing.
- A protest can address the value or a denied exemption. It does not change the tax rates set by the taxing units.
- A protest may or may not lower your value. Results are not guaranteed.
A homestead also has a limit on how fast its appraised value can rise year to year, which begins after your first qualifying year. That limit does not cover the value of new improvements, such as an addition.
New construction, MUDs, and PIDs: extra items to ask about
New construction and supplemental bills
Value is based on the property’s condition on January 1. A home still being built on that date may be taxed on land and only the completed part of the structure. After the home is finished, it is generally appraised at full value on a later January 1. In addition, state law allows an appraisal district to add property omitted from the roll in the previous three years, which can result in a supplemental or corrected bill. That means a builder’s or seller’s recent tax bill may not show what your tax bill will be once the home is fully appraised. Ask your loan officer how taxes were estimated for your loan.
Municipal utility districts (MUDs)
Some newer neighborhoods are inside a MUD, which levies its own tax on top of the others. Texas law requires sellers to provide buyers with notice of the district’s current tax rate before the contract is signed. Ask how and when the MUD bills.
Public improvement districts (PIDs)
A PID is different. It charges a special assessment, not a property tax, to pay for improvements or services in the district. Sellers must give buyers a statutory notice before the contract is signed, and the buyer signs; levies are recorded at closing. The assessment is usually paid in annual installments, may be paid in full at any time, and may show up on the county tax bill or be collected by a trustee instead. Some lenders include it in escrow, so ask which applies to your home.
| Item | What it is | What to ask |
|---|---|---|
| Property tax | Local taxes based on value, less exemptions | Which units tax this address, and is the homestead exemption in place? |
| MUD tax | An additional district tax in some neighborhoods | What is the current rate, and who collects it? |
| PID assessment | A special assessment, not a tax | What are the installments, and is it paid through escrow? |
| Escrow | A monthly set-aside for taxes and insurance | How was the tax estimate calculated, and how often can it change? |
Questions to ask before you make an offer
- What are the current tax bill and exemptions on this specific address?
- Is the home new, or recently improved, so the appraised value may rise?
- Is it in a MUD or PID, and where can I see the notice?
- Will my loan use escrow, and what is the estimated tax amount?
Frequently asked questions
Does my lender set my property taxes?
No. Local taxing units set rates, and the appraisal district sets values. Your lender or servicer collects part of the bill through escrow, if your loan has one.
Why did my escrow payment change?
Because taxes and insurance can change from year to year. If either goes up or down, the escrow portion of your payment can change as well.
Is a PID assessment the same as a property tax?
No. It is a special assessment, though it can look like a tax and may appear on your tax bill.
