Estimate Your Texas Property Tax, Homestead Savings and Monthly Escrow
Use this calculator to estimate your Texas property tax bill before you receive the official statement. Enter your property value, exemptions and combined local tax rate to estimate taxable value, annual tax, monthly escrow and possible exemption savings.
Texas Property Tax Calculator
This calculator works best when you use numbers from your county appraisal district record and tax statement. If you do not know your exact combined tax rate, use your previous year’s total rate as a rough estimate, then verify it with your county tax office or the Texas Comptroller tax rate page.
Texas Property Tax Formula in Simple Words
Texas property tax is usually estimated by subtracting approved exemptions from the appraised or assessed value, then applying the combined local tax rate for your property.
Estimated Tax = Taxable Value × Combined Local Tax Rate
Taxable Value = Appraised Value – Approved Exemptions
Texas rates are often shown as dollars per $100 of taxable value. A rate of 1.85 means about $1.85 per $100 of taxable value, which is similar to 1.85% for quick estimating.
How to Find the Right Texas Property Tax Rate
The best tax rate is the combined rate shown for your exact property. Two homes in the same city can have different total rates if they are in different school districts, MUDs, emergency service districts or special districts.
The most accurate starting point is your last property tax statement because it lists each taxing unit and rate.
The county tax office or collector usually shows tax bills, balances, payment portals and taxing unit details.
The Texas Comptroller provides reported tax rate data, but you still need to match the correct taxing units for your property.
Open the Texas Comptroller tax rates page to review statewide rate data reported by appraisal districts.
Exemptions to Enter in the Calculator
Enter the total exemption amount that applies to the taxing unit you are estimating. This is where many estimates go wrong because exemption amounts can vary by taxing unit.
| Exemption Type | Who It Helps | Calculator Tip |
|---|---|---|
| Residence Homestead | Homeowners who own and occupy the property as their principal residence. | Enter the exemption amount shown on your CAD record or tax statement. |
| Over-65 Exemption | Qualifying homeowners age 65 or older. | Use this calculator with our Texas senior tax exemption guide. |
| Disabled Person | Qualifying disabled homeowners. | Check whether school tax ceiling or other limits apply. |
| Disabled Veteran | Veterans who qualify under Texas disability rating rules. | Use the exact exemption amount from the official CAD record. |
| Local Optional Exemption | Homeowners in cities, counties or special districts that adopted extra relief. | Do not assume every taxing unit offers the same optional exemption. |
For official exemption rules and forms, use the Texas Comptroller property tax exemptions page.

Common Texas Property Tax Estimate Mistakes
| Mistake | Why It Creates a Wrong Estimate | Better Action |
|---|---|---|
| Using only county tax rate | Your total bill usually includes school, city and other local taxing units. | Use the combined rate for your exact property. |
| Ignoring exemptions | Homestead, over-65 and veteran exemptions can change taxable value. | Check your CAD record before estimating. |
| Using seller’s tax bill | Seller exemptions or ceilings may not transfer to the buyer. | Estimate based on your expected ownership and exemption status. |
| Confusing appraised value and taxable value | The tax bill is based on taxable value after exemptions and limits. | Use taxable value when available. |
| Forgetting penalties | Late taxes can include penalty and interest after the due date. | Contact the county tax office for payoff amounts. |

Official Texas tax bills can include local rates, exemptions, ceilings, special districts, late penalties, interest and corrections that a simple calculator may not know.
Can this calculator estimate monthly escrow?
Yes. It divides the estimated annual tax by 12. Your lender may collect more or less depending on insurance, escrow cushion and account rules.

Yes, but buyers should be careful. The seller’s current bill may include exemptions or tax ceilings that may not apply after purchase.
Does Texas have one statewide property tax rate?
No. Texas has no state property tax. Local taxing units set rates, so tax bills vary by location and property boundaries.
