What Is the Texas Property Tax Calculator?
The Texas Property Tax Calculator estimates the annual and monthly property tax on a Texas home from its appraised value, the Texas homestead exemption, and your local tax rate per $100 of value. Texas has no state income tax, so local property taxes fund schools, roads, and emergency services, which makes this estimate essential before you buy or budget.
- • Home buyers: Estimate the escrow payment and true monthly cost of owning a specific Texas home.
- • Current owners: Check whether claiming homestead or over-65 exemptions lowers your bill.
- • Budget planners: Convert the annual tax into a monthly figure for household cash-flow planning.
- • Relocators: Compare the tax load of homes across Texas counties and school districts.
The calculator works on the same math your county tax office uses: appraised value minus exemptions, times the rate per $100. Because Texas appraises most property at 100% of market value, the appraised value is effectively the full market value rather than a discounted assessment.
You only need three inputs to get a useful result: how much your home is worth, the exemption total you qualify for, and the combined tax rate for your address. The tool returns the annual tax, a monthly escrow amount, the taxable value, and the effective rate as a percent of the full value.
Because Texas has no state income tax, pair your property estimate with the Texas paycheck calculator to see your full local tax picture.
How the Calculator Works
The Texas Property Tax Calculator applies the standard Texas formula in three steps: subtract exemptions from the appraised value, then multiply the remaining taxable value by the tax rate expressed per $100 of value.
- Appraised value: The market value your appraisal district assigns, typically 100% of market value in Texas.
- Exemptions: Total homestead exemptions removed before tax, including the $100,000 school-district portion and any local or over-65 amounts.
- Tax rate per $100: The combined rate of all taxing units, expressed as dollars per $100 of taxable value.
- Taxable value: Appraised value minus exemptions; this is the base the rate is applied to.
Dividing the annual tax by 12 gives the monthly amount lenders collect into an escrow account. If your exemptions equal or exceed the appraised value, the taxable value and the tax both fall to zero.
The effective tax rate shows what you actually pay against the full value. It is lower than the adopted rate whenever exemptions reduce your taxable base.
Houston-area home
Appraised value $350,000, exemptions $100,000, rate $2.10 per $100.
Taxable value = 350,000 - 100,000 = 250,000. Annual tax = 250,000 x (2.10 / 100) = 250,000 x 0.021.
Annual tax = $5,250, about $437.50 per month.
The effective rate is 1.50% because the exemption lowered the taxed base below the full market value.
According to Texas Comptroller of Public Accounts, The Texas Comptroller's Property Tax Assistance Division publishes the appraisal rules, exemption amounts, and local rates that every taxing unit follows.
Since Texas trades a state income tax for local property and sales tax, the Texas sales tax calculator shows the rest of that burden.
Key Concepts Explained
Four ideas explain why Texas property tax bills vary so much from one address to the next.
Appraised value and the 100% assessment ratio
Texas law requires most property to be appraised at its market value, so unlike states that assess a fraction, your appraised value is the full market value used in the formula.
Homestead exemption
The residence homestead exemption removes $100,000 of school-district value and lets local districts add optional exemptions. It directly shrinks the taxable base before the rate is applied.
Tax rate per $100 of value
Texas rates are quoted per $100 of taxable value, not as a flat percent. A rate of $2.10 means $2.10 of tax for every $100, or 2.10% of the taxable value.
Effective versus adopted rate
The adopted rate is what the collector applies; the effective rate is your payment divided by full appraised value and falls when exemptions lower the taxable base.
Together these concepts show why two homes at the same price can owe different amounts: the exemption total and the local rate matter as much as the price.
A home in a low-rate rural district can owe far less than a similarly priced home inside a city school district with higher MUD and hospital rates. The appraised value is only half the story; the rate per $100 set by each taxing unit does the rest.
Because Texas appraises at 100% of market value, the appraised value already reflects what a willing buyer would pay. That removes the fractional-assessment math used in some states and keeps the formula intuitive: subtract exemptions, multiply by the rate.
To see how Texas local rates compare with other states, the state sales tax comparison calculator puts the structure in context.
How to Use This Calculator
Follow these steps to get a reliable estimate for your Texas property.
- 1 Find your appraised value: Look up the current appraised value on your county appraisal district notice or website.
- 2 Total your exemptions: Add the $100,000 school-district homestead exemption to any local, over-65, or disabled exemptions you claim.
- 3 Enter your combined tax rate: Use the total rate from your tax statement, shown per $100 of value, not a single district's rate.
- 4 Read the results: Note the annual tax, monthly escrow amount, taxable value, and effective rate.
- 5 Compare scenarios: Re-run with and without exemptions to see the savings from filing your homestead exemption.
A San Antonio buyer comparing two offers can enter each appraised value with the same rate and exemptions to see the monthly tax difference before making an offer.
After you know the monthly tax, the gross-to-net calculator helps fit it into your take-home budget.
Benefits of Using This Calculator
The Texas Property Tax Calculator helps you act on the result rather than just see a number.
- • Plan escrow accurately: The monthly figure feeds directly into a mortgage payment estimate so you know the full carrying cost.
- • Quantify exemption savings: Running the tool with and without exemptions shows the dollars you save by filing a homestead exemption.
- • Compare counties and ISDs: Different local rates change the bill more than small price differences, helping you choose where to live.
- • Catch appraisal errors early: If the estimate is far below your bill, your appraised value may be worth protesting during the annual window.
- • Budget for no state income tax trade-off: Texas replaces income tax with property and sales tax, so the estimate shows the real local tax burden you carry.
Because Texas relies on local property taxes instead of a state income tax, this number is a large part of your total tax picture.
Running the estimate before you close lets you compare the all-in monthly cost of two offers rather than only the listed price. A lower price in a higher-rate district can cost more per month than a higher price where exemptions and rates are friendlier.
Landlords can apply the same rate math to investment homes using the rental property tax calculator before setting rent.
Factors That Affect Your Results
Several inputs and rules change the bill, and a few limits apply to any estimate.
Local tax rate by district
Your combined rate blends school, county, city, and special-district rates; small rate gaps produce large dollar differences across Texas.
Homestead and over-65 exemptions
Filing exemptions lowers the taxable base, which is the fastest legal way to cut the bill for an owner-occupied home.
Appraised value changes
Rising local values push the bill up even when the rate stays flat, which is why annual review matters.
Special districts and MUDs
Municipal utility districts and hospital districts add separate rates that raise the combined total in some neighborhoods.
- • The estimate excludes non-ad valorem charges such as MUD debt service or special assessments that may appear on your statement.
- • Rates and exemption amounts change by legislative session and locale; use current values from your tax office for a binding figure.
Treat the output as a planning estimate. Your official bill follows the rates and exemptions adopted each year by your local taxing units.
If your appraised value jumps during a countywide revaluation, your bill can rise even when the adopted rate stays flat or drops. Checking the estimate each spring, before you pay, is the best way to spot a value you should protest.
Exemptions rarely apply automatically for new buyers. Filing the residence homestead exemption with your appraisal district is what triggers the school-district savings, and the over-65 freeze only starts once you apply.
According to Texas Tax Code Chapter 11, Texas Tax Code Chapter 11 sets the residence homestead exemption at $100,000 of school-district value plus at least $10,000 more for homeowners 65 or older or disabled.
According to Texas Tax Code Chapter 26, Texas Tax Code Chapter 26 governs how each taxing unit adopts a tax rate expressed per $100 of valuation.

Frequently Asked Questions
Q: How is Texas property tax calculated?
A: Texas taxing units appraise most property at 100% of market value. Subtract any homestead exemptions, then multiply the taxable value by the combined tax rate, which is quoted per $100 of value. For example, $250,000 taxable value at $2.10 per $100 produces a $5,250 annual bill.
Q: What is the Texas homestead exemption amount?
A: The statewide residence homestead exemption removes $100,000 of school-district value as of the 2024 tax year, set by Texas Tax Code Section 11.13. Counties, cities, and other districts may add their own optional exemptions on top of that base amount.
Q: How much is the over-65 or disabled property tax exemption in Texas?
A: Homeowners who are 65 or older or who are disabled receive at least $10,000 of additional school-district exemption and a freeze of their school-tax rate. Many local jurisdictions add further exemptions, so total savings vary by address.
Q: Does Texas have a state property tax rate?
A: No. Texas has no state property tax. The rate is set locally by each school district, county, city, and special district, then combined. That is why the same home can owe very different amounts across counties and even neighborhoods.
Q: What is a Texas effective tax rate versus the adopted tax rate?
A: The adopted rate is what the tax collector applies per $100 of value. The effective rate is your actual payment divided by full appraised value; it drops below the adopted rate when exemptions lower your taxable value.
Q: How do I lower my Texas property tax bill?
A: File your residence homestead exemption with the county appraisal district, claim over-65 or disabled exemptions if eligible, and protest the appraised value during the annual protest window. Lowering appraised value or adding exemptions both reduce the taxable base.
