Texas property tax calculator, built for exam math.
Calculate taxable value and annual property tax using appraised value, the homestead exemption, and the Texas rate stated per $100 of value.
Texas property tax math starts with taxable value. Subtract the homestead exemption from the appraised value first, then divide taxable value by 100 and multiply by the rate per $100 of value. For a homestead, the 10% appraisal cap limits how much the appraised value can rise each year before you start. Texas has no state income tax and no statewide real estate transfer tax.
Divide taxable value by 100, then multiply by the rate per $100 of value.
Subtract the homestead exemption, divide by 100, then multiply by the rate per $100.
A qualified homestead exemption reduces taxable value before the rate is applied.
A homestead's appraised value cannot rise more than 10% per year, regardless of market value.
If a question states mills, convert: 1 mill = $1 per $1,000 = $0.10 per $100.
Start with appraised value, subtract the exemption, then apply the per-$100 rate.
Homestead matters because a qualified homestead can claim an exemption that lowers the taxable value.
For a homestead, this is the appraised value after the 10% homestead appraisal cap has been applied by the appraisal district.
Texas states tax rates per $100 of value. A mills mode is included for questions that use the per-$1,000 unit.
Texas rates are stated per $100 of value. Divide the taxable value by 100, then multiply by the rate. Dividing by 1,000 is the mills unit.
The homestead exemption reduces the taxable value before the rate is applied; it does not reduce the tax dollar-for-dollar.
Subtract the exemption before applying the rate. Do not multiply the full appraised value by the rate first.
The 10% homestead appraisal cap limits how much a homestead's appraised value can rise year over year. It changes the appraised value going in, not the rate.
Apply the homestead exemption to the appraised value first, then divide by 100 and multiply by the rate. Dividing by 1,000 is the mills unit, not the Texas per-$100 standard.
Five Texas property tax traps to check before you trust the answer.
- Unit trap: divide taxable value by 100 (per $100), not 1,000, unless the rate is stated in mills.
- Exemption sequence trap: subtract the homestead exemption before applying the rate.
- Exemption value trap: the exemption reduces taxable value, not the tax dollar-for-dollar.
- Homestead eligibility trap: do not apply a homestead exemption to a rental, second home, or raw land.
- 10% cap trap: the homestead appraisal cap limits the appraised value going in; it is not a rate.

A home has a $260,000 taxable value and a tax rate of $2.10 per $100 of value. What is the annual property tax?
Using this as a Texas homestead exemption calculator
This tool doubles as a Texas homestead exemption calculator. Enter the appraised value and the homestead exemption amount the question gives. The calculator subtracts the exemption from the appraised value to produce the taxable value, then applies the rate per $100. Texas homestead exemption amounts vary by taxing unit, so use the figure in the stem rather than memorizing a single number.
What the exemption produces
The result is a single taxable value: appraised value minus the homestead exemption. Stop there if a question asks only for taxable value, or continue to apply the rate per $100 for the tax. For a qualified homestead, the 10% appraisal cap limits how much the appraised value can rise year over year before the exemption is subtracted.
Texas protects a qualified residence homestead with a 10% appraisal cap: the appraised value used for taxes cannot increase more than 10% per year (plus the value of new improvements), even when market value rises faster. This is a Texas rule under the Texas Tax Code, not any other state's program. Confirm current exemption amounts and cap details with the Texas Comptroller.
Which taxable value should you use?
The exam often gives appraised value, a homestead exemption, and a rate per $100. Sort those pieces before you touch the calculator.
Did the problem give appraised value or taxable value?
If it gives taxable value, use it directly. If it gives appraised value and an exemption, subtract the exemption first.
Is the property a qualified homestead?
Only a primary-residence homestead can claim the homestead exemption. Do not subtract it for rentals, second homes, or raw land.
Does the problem describe a year-over-year increase with the 10% cap?
Apply the 10% homestead appraisal cap to find this year's appraised value first, then subtract the exemption. The cap limits the appraised value, not the rate.
Is the rate stated per $100 or in mills?
Texas states rates per $100 of value. If a question uses mills, convert to per $100 (divide mills by 10) or divide value by 1,000 instead of 100.
Does the problem ask for tax or taxable value?
Stop where the question asks. Some exam answers are the taxable value, not the final tax bill.
What this calculator is built to answer
This calculator turns appraised value, the homestead exemption, and the rate per $100 into the taxable value and annual tax a Texas exam question is likely to ask for.
Why property tax math trips students up
Property tax questions are not hard because of the multiplication. They are hard because candidates divide by 1,000 instead of 100, or apply the rate before subtracting the exemption.
| Concept | Exam rule | Common trap |
|---|---|---|
| Rate per $100 | Dollars of tax per $100 of taxable value | Dividing by 1,000 (the mills unit) instead of 100. |
| Taxable value | Appraised value minus the homestead exemption | Using appraised value after an exemption is given. |
| Homestead exemption | Reduces taxable value of a qualified primary residence | Applying it to a rental, second home, or raw land. |
| 10% appraisal cap | Limits a homestead's appraised-value increase to 10% per year | Using market value instead of the capped appraised value. |
| Mills conversion | 1 mill = $1 per $1,000 = $0.10 per $100 | Forgetting to convert mills to a per-$100 rate. |
| Final tax | Taxable value / 100 x rate per $100 | Skipping the divide-by-100 step. |
Five Texas property tax patterns to know cold.
These examples cover the setups that decide most property tax math questions: the per-$100 rate, the homestead exemption, the 10% appraisal cap, non-homestead property, and mills conversion.
$260,000 taxable value at $2.10 per $100
Divide by 100 for a per-$100 rate, not by 1,000.
$310,000 appraised value, $40,000 homestead exemption, $1.95 per $100
Subtract the exemption before applying the rate.
Last year appraised $250,000, market value now $300,000, 10% cap
Use the capped appraised value, not the higher market value, for a homestead.
$180,000 appraised value at $2.40 per $100, non-homestead
Do not apply a homestead exemption to a rental property.
Rate stated as 19.5 mills
Mills are per $1,000; the Texas standard is per $100.
The property tax mistakes that cost easy points.
Millage questions reward careful order. Find taxable value, choose the right millage category, then calculate.
Dividing by 1,000 for a per-$100 rate
Texas rates are per $100 of value. Divide the taxable value by 100, not 1,000, unless the rate is stated in mills.
Using appraised value after an exemption is given
When the problem gives a homestead exemption, subtract it before applying the rate. The tax is based on taxable value.
Treating the exemption like a tax credit
The homestead exemption reduces taxable value before the rate, not the tax dollar-for-dollar. A $40,000 exemption is not a $40,000 tax savings.
Solving past the ask
Some questions ask for taxable value, some ask for tax, and some ask for the effect of the exemption or cap. Stop once the answer is reached.
Treating the 10% cap like a rate
The 10% homestead appraisal cap limits how much appraised value can rise each year. It changes the value going in, not the per-$100 rate.
Applying the homestead exemption to a rental
Only a qualified primary-residence homestead receives the exemption and the 10% cap. Rentals, second homes, and raw land do not.
Turn every property tax question into four steps.
Property tax questions become manageable when you separate value, exemption, rate, and the final ask.
Start with appraised value unless the problem already gives taxable value.
For a homestead, apply the 10% appraisal cap if the question describes a year-over-year increase.
Subtract the homestead exemption before applying the rate.
Divide taxable value by 100, multiply by the rate per $100, then stop at the amount the question asks for.
What to study next if property tax is on your weak list.
Property tax math connects to proration, the homestead exemption, and the broader Texas math formula set.
How do you calculate property tax on the Texas real estate exam?+
Subtract any homestead exemption from the appraised value to get taxable value. Then divide taxable value by 100 and multiply by the rate per $100 of value. Texas states tax rates per $100, not per $1,000.
What does the rate per $100 mean in Texas property tax math?+
A rate of $2.10 per $100 means $2.10 of tax for every $100 of taxable value. For example, $260,000 taxable value at $2.10 per $100 is $260,000 divided by 100, then multiplied by $2.10, which equals $5,460.
How does the Texas homestead exemption work?+
A homestead exemption reduces the taxable value of a qualified primary residence before the tax rate is applied, which lowers the bill. Texas also applies a 10% homestead appraisal cap that limits how much the appraised value can increase in a year.
Can I use this as a Texas homestead exemption calculator?+
Yes. Enter the appraised value and the homestead exemption amount, and the tool returns the taxable value after the exemption and the resulting tax. Use the exemption figure the question gives, because amounts vary by taxing unit.
Is this calculator a live Texas property tax estimator?+
No. It is built for Texas real estate exam preparation. Live property tax bills combine multiple taxing units, local exemptions, the 10% appraisal cap, and county-specific rates.
How does the 10% appraisal cap affect a Texas exam property tax problem?+
If the stem describes a year-over-year increase for a homestead, apply the 10% cap to last year's appraised value first to find this year's appraised value. Then subtract the exemption and apply the rate.
What is the biggest property tax mistake on the Texas exam?+
The biggest mistake is dividing by 1,000 instead of 100, or applying the rate before subtracting the exemption. Always find taxable value first, then divide by 100 and multiply by the rate per $100.
A homestead has a $310,000 appraised value and a $40,000 homestead exemption. The tax rate is $1.95 per $100 of value. What is the annual property tax?
Taxable value: $310,000 - $40,000 = $270,000. Tax: $270,000 / 100 x $1.95 = $5,265.
