To calculate your Tarrant County property tax, take your home’s appraised value, subtract any exemptions each taxing entity grants you, divide by 100, and multiply by that entity’s tax rate. You do this once for every taxing unit on your property record and add the results. The Tarrant County Tax Office also publishes a free online property tax calculator that pulls your current values, exemptions, and rates automatically, so most homeowners can skip the arithmetic entirely.1Tarrant County. Tax Estimator
Tarrant County doesn’t have one countywide rate. Your property sits inside overlapping jurisdictions, each with its own rate: the county, your city, your independent school district, Tarrant County College District, and JPS Health Network. Whether you use the estimator or run the numbers by hand, you need the same three inputs for each of those entities.
The Three Numbers You Need Before You Calculate
Pull up your property record on the Tarrant Appraisal District’s public search portal before you start.2Tarrant Appraisal District. Property Search – Public Portal You can search by owner name, address, or account number. The record carries everything the calculation depends on.
Appraised value. Your record shows two values: market value (what the home would sell for) and appraised value (the figure actually used for taxes).3Texas Comptroller of Public Accounts. Valuing Property Use the appraised value. On a homesteaded property these numbers often differ because of the 10% cap described below.
Exemptions on file. The record lists which exemptions each entity has granted on your account. Exemptions only count if they’re officially recorded with TAD. If one you qualify for isn’t showing, you have to file for it; it won’t be applied retroactively for past years.
Each entity’s rate. Your record also lists every taxing entity assigned to your parcel and the current rate for each. Texas rates are stated per $100 of taxable value. Save or print this page so you have every rate in one place.
The Formula, Worked Through
For each taxing entity on your record:
- Start with your appraised value (after the 10% cap, if it applies).
- Subtract the exemptions that specific entity grants you. That’s your taxable value for that entity.
- Divide by 100.
- Multiply by that entity’s rate.
Say your home has a capped appraised value of $350,000 and you have the general homestead exemption. For the school district, subtract the $140,000 homestead exemption to get a taxable value of $210,000.4State of Texas. Texas Tax Code TAX 11.13 – Residence Homestead Divide $210,000 by 100 to get 2,100. If the school district rate is $1.05 per $100, your school tax is $2,205.
For a city with no homestead exemption and a rate of $0.55 per $100, use the full $350,000: divide by 100 to get 3,500, then multiply by $0.55 for $1,925 in city taxes. Repeat for every entity on your record and add the results. That total is your estimated annual bill.
The common mistake is applying the school district’s $140,000 homestead exemption to every entity. It doesn’t. That exemption only reduces school district taxes. Other entities may offer their own homestead exemptions, but the amounts differ and are often much smaller or zero. Check the exemption column for each entity separately.
Using the Tarrant County Online Estimator
If you’d rather skip the arithmetic, the Tarrant County Tax Office’s free estimator does all of it for you.1Tarrant County. Tax Estimator Search for your property by account number or address through the Tarrant County Tax Office site.5Tarrant County. Tarrant County Tax Office No login is required.
Once your property loads, the tool pulls in your current taxing entities and rates. You can change the appraised value or toggle exemptions on and off to see how each change moves the bottom line. It will also estimate what your bill would be if your appraisal changed, and it can calculate penalty and interest on a past-due balance. If you’re thinking about filing a protest, running the “what if” with a lower value is the fastest way to see what a reduction would actually save you.
Exemptions That Change the Math
Exemptions reduce your appraised value before any rate is applied, so they come straight off the top of the calculation. Four matter most in Tarrant County.
General Residence Homestead
If you own and live in the home as your primary residence, you get a $140,000 exemption from school district taxes.4State of Texas. Texas Tax Code TAX 11.13 – Residence Homestead This is the largest single exemption most homeowners receive. Your city, the county, and the hospital district may adopt their own optional homestead exemptions, usually smaller. Your TAD record shows which entities have granted you one.
Over-65 and Disability
Homeowners who are 65 or older or who have a qualifying disability get an additional $60,000 school district exemption on top of the standard $140,000, for a total school exemption of $200,000.4State of Texas. Texas Tax Code TAX 11.13 – Residence Homestead Other entities may adopt an optional exemption of at least $3,000 for these residents. Qualifying also triggers a tax ceiling on your school district taxes: the school portion of your bill freezes at the amount you paid in the year you first qualified and can’t increase unless you add improvements.
Disabled Veteran
Texas offers a separate exemption schedule for disabled veterans, applied to any one property the veteran designates:
- 10% to 29% rating: up to $5,000 off the assessed value
- 30% to 49%: up to $7,500
- 50% to 69%: up to $10,000
- 70% or higher: up to $12,000
Veterans rated at 100% disability, or determined individually unemployable by the VA, qualify for a complete exemption and pay zero property tax on their homestead.6State of Texas. Texas Tax Code TAX 11.22 – Disabled Veterans
The 10% Homestead Appraisal Cap
If you’ve had a homestead exemption on the property for at least two consecutive years, your appraised value can’t rise more than 10% a year regardless of market movement. The appraisal district has to limit the appraised value to the lesser of current market value or last year’s appraised value plus 10%, plus any new improvements.7State of Texas. Texas Tax Code TAX 23.23 – Limitation on Appraised Value of Residence Homestead If market value jumped 25% in a year, your appraised value still rises only 10%.
When you calculate manually, use the capped appraised value, not the market value. The two are listed separately on your TAD record, and the gap can be large.
If Your Appraised Value Looks Too High
Every dollar on the appraised-value line flows through the entire calculation, year after year, so if the starting number is wrong the bill is wrong. You can protest to the Tarrant Appraisal Review Board, a separate body from the appraisal district.8Tarrant Appraisal District. Tarrant Appraisal Review Board The deadline to file a notice of protest is May 15, or 30 days after your appraisal notice is mailed, whichever is later. Miss it and you’re locked in for the year.
Many valuations are adjusted through an informal review with TAD before a hearing is ever held. If informal talks don’t resolve it, the ARB schedules a hearing where you present evidence such as comparable sales, photos of condition issues, or an independent appraisal, and the board can order the appraisal district to lower the value.9Tarrant Appraisal District. Property Tax Protest and Appeal Procedures For a residential protest backed by two or three solid comparable sales, the process is manageable without hiring help.
