QUICK ANSWER
For exam math, property tax usually follows this sequence: find taxable value, then apply the tax rate. Taxable value generally means appraised or assessed value minus exemptions. If the rate is a percent, multiply taxable value by the percent as a decimal. If the rate is a mill rate, remember that 1 mill equals $1 of tax per $1,000 of value. Texas caveat: Texas has no state property tax. Local taxing units set property tax rates, appraisal districts appraise property, and exemptions are handled locally through appraisal districts.

Property tax math looks simple until the question adds exemptions, tax rates, mill rates, or prorations.
The basic idea is still manageable:
Property tax = taxable value x tax rate
But on the Texas real estate exam, you need to know what value to use.
Is the question giving:
- Market value?
- Appraised value?
- Assessed value?
- Taxable value?
- Exemption amount?
- Tax rate?
- Mill rate?
- Annual tax to prorate?
If you grab the wrong value, the math can be perfect and the answer still wrong.
This guide explains property tax and mill-rate calculations for exam purposes, then adds the Texas-specific caveats you should know without turning the post into tax advice.

What Property Tax Math Appears On The Texas Real Estate Exam?
Pearson VUE's current Texas sales content outline lists Real Estate Math Calculations in the National/General portion. Under property valuation, the outline includes assessed value and property taxes. Under settlement and closing costs, it also lists prorated items, debits, and credits.
That means property tax can show up in more than one way:
| Exam context | What it may test |
|---|---|
| Property valuation | Assessed value, taxable value, tax rate, annual tax |
| Settlement and closing costs | Tax prorations, seller debit, buyer credit |
| Investment or ownership | Carrying costs, annual expenses |
| Texas-specific knowledge | Understanding that Texas property tax is local, not state-level |
This article uses original educational examples, not copied exam questions.
Texas Property Tax Caveats
Texas property tax has its own vocabulary and structure.
The Texas Comptroller states that Texas has no state property tax. The Comptroller's office does not collect property tax or set property tax rates. Local taxing units set rates and use the revenue for local services such as schools, streets, roads, police, and fire protection.
The Comptroller also explains that appraisal districts appraise property value as of Jan. 1 each year, local appraisal review boards hear certain disputes, and local tax assessor-collectors often collect taxes for taxing units.
For exam math, the practical lesson is this:
Do not assume one statewide Texas property tax rate.
Use the tax rate, exemption amount, appraised value, assessed value, or taxable value given in the question.
Texas caveats to remember
| Caveat | Why it matters |
|---|---|
| Texas has no state property tax | The exam may test local vs state understanding |
| Local taxing units set rates | Do not assume one Texas rate |
| Appraisal districts appraise property | Appraised value and tax rate are separate ideas |
| Exemptions can reduce taxable value | Subtract exemptions before applying the rate when the question says so |
| Several taxing units may tax the same property | A property can have school, city, county, and special district taxes |
| Property tax rates change | Use the rate in the question |
This post is educational exam prep, not tax, legal, or appraisal advice.
Core Formula Sheet
Use this formula sheet for exam math.
| Need | Formula |
|---|---|
| Taxable value | Appraised or assessed value - exemptions |
| Property tax using percent | Taxable value x tax rate |
| Tax rate from tax amount | Tax / taxable value |
| Taxable value from tax and rate | Tax / tax rate |
| Tax using mills | Taxable value x mills / 1,000 |
| Mills from tax and value | Tax x 1,000 / taxable value |
| Dollars per $100 rate | Taxable value / 100 x rate per $100 |
| Annual tax proration | Annual tax / 360 or 365 x days |
| Monthly tax estimate | Annual tax / 12 |
Convert percentages to decimals:
| Percent | Decimal |
|---|---|
| 1% | 0.01 |
| 1.5% | 0.015 |
| 2% | 0.02 |
| 2.25% | 0.0225 |
| 3% | 0.03 |
If the question gives a rate in mills, do not convert it like a normal percent. Use mills / 1,000.
Assessed Value, Appraised Value, And Taxable Value
The exam may use these terms in a simplified way. Texas sources may use specific statutory language. The safest exam strategy is to follow the wording of the question.
Market value
Market value is the value the property would likely bring under market conditions. The Texas Comptroller's valuing-property page explains that, with few exceptions, appraisal districts appraise taxable property at market value as of Jan. 1.
Appraised value
In Texas, the appraisal district determines appraised value for property tax purposes. The Comptroller explains that each appraisal district determines the value of taxable property within county boundaries.
Assessed value
Many national real estate math questions use "assessed value" as the value to which the tax rate is applied. If the question gives assessed value and no exemptions, use assessed value as the tax base.
Taxable value
Taxable value is the value after exemptions or reductions that the question tells you to apply.
For exam math:
Taxable value = value given - exemption amount
Then:
Tax = taxable value x tax rate
The main move is sequence. Do not apply the tax rate before subtracting the exemption.
How Exemptions Change The Math
The Texas Comptroller explains that exemptions may remove a percentage or fixed dollar amount of a property's appraised value from taxation. A total exemption excludes the entire value from taxation.
For exam math, you usually do not need to memorize current exemption amounts unless the question gives them. You need to know how exemptions affect taxable value.
Fixed-dollar exemption
Example:
A property is appraised at $300,000. It has a $40,000 exemption. What is the taxable value?
$300,000 - $40,000 = $260,000
Answer: $260,000 taxable value.
Percentage exemption
Example:
A property is appraised at $300,000. It has a 20% exemption. What is the taxable value?
Exemption amount:
$300,000 x 0.20 = $60,000
Taxable value:
$300,000 - $60,000 = $240,000
Answer: $240,000 taxable value.
Multiple exemptions
If a question gives more than one exemption, apply the wording exactly.
Example:
A property is appraised at $400,000. The question gives a $50,000 exemption and says no other exemptions apply. Taxable value is:
$400,000 - $50,000 = $350,000
Do not add exemptions or limits that the question does not give.
Percent Tax Rate Calculations
Percent tax rate questions are part, whole, and rate problems.
Use:
Tax = taxable value x tax rate
Example: tax from percent rate
A property has taxable value of $250,000. The tax rate is 2.4%. What is the annual tax?
Convert the rate:
2.4% = 0.024
Calculate:
$250,000 x 0.024 = $6,000
Answer: $6,000.
Example: rate from tax and value
A property has taxable value of $300,000 and annual tax of $6,600. What is the tax rate?
$6,600 / $300,000 = 0.022
Answer: 2.2%.
Example: taxable value from tax and rate
Annual tax is $7,500 and the tax rate is 2.5%. What is the taxable value?
$7,500 / 0.025 = $300,000
Answer: $300,000.
Related page: The T-bar / circle method explained
Mill-Rate Calculations
Mill-rate math is a national real estate exam concept.
One mill equals $1 of tax per $1,000 of value.
Use:
Tax = taxable value x mills / 1,000
Example: tax from mills
A property has taxable value of $200,000. The tax rate is 30 mills. What is the annual tax?
$200,000 x 30 / 1,000 = $6,000
Answer: $6,000.
Another way:
$200,000 / 1,000 = 200
200 x $30 = $6,000
Both methods work.
Example: mills from tax and value
A property has taxable value of $250,000 and annual tax of $5,000. What is the mill rate?
$5,000 x 1,000 / $250,000 = 20
Answer: 20 mills.
Mill rate to percent
To convert mills to a decimal rate:
mills / 1,000
30 mills:
30 / 1,000 = 0.03 = 3%
20 mills:
20 / 1,000 = 0.02 = 2%
But for exam speed, it is often easier to use value x mills / 1,000.
Texas Rate Per 100 Caveat
Texas property tax rates are commonly shown as dollars per $100 of taxable value in local tax data and bills.
If a question gives a rate per $100, do not treat it as a percent unless you convert correctly.
Use:
Tax = taxable value / 100 x rate per $100
Example: rate per $100
A property has taxable value of $300,000. The tax rate is $2.10 per $100 of taxable value. What is the annual tax?
Divide value by 100:
$300,000 / 100 = 3,000
Multiply by the rate:
3,000 x $2.10 = $6,300
Answer: $6,300.
That $2.10 per $100 is equivalent to 2.10%, but the per-$100 setup is often clearer.
Why this matters
You may see property tax questions stated in different ways:
| Rate format | Example | Calculation style |
|---|---|---|
| Percent | 2.1% | Value x 0.021 |
| Mills | 21 mills | Value x 21 / 1,000 |
| Dollars per $100 | $2.10 per $100 | Value / 100 x 2.10 |
All three examples produce the same tax on the same value:
$300,000 x 0.021 = $6,300
$300,000 x 21 / 1,000 = $6,300
$300,000 / 100 x $2.10 = $6,300
The answer is the same. The setup changes.
Property Tax Proration
Property tax can also appear in closing math.
In a proration problem, you are not just calculating annual tax. You are dividing tax between buyer and seller based on ownership days.
Pearson's math notes say that if a question requires prorated amounts, the question will specify whether to use a 360-day or 365-day year and whether the day of closing belongs to the buyer or seller.
Use:
Daily tax = annual tax / stated day count
Proration = daily tax x number of days
Example: 365-day proration
Annual taxes are $5,475. The question says use a 365-day year. The seller owns the property for 120 days. What is the seller's share?
Daily tax:
$5,475 / 365 = $15
Seller share:
$15 x 120 = $1,800
Answer: $1,800.
Example: 360-day proration
Annual taxes are $3,600. The question says use a 360-day year. The seller owns the property for 75 days. What is the seller's share?
Daily tax:
$3,600 / 360 = $10
Seller share:
$10 x 75 = $750
Answer: $750.

Daily tax:
$4,800 / 360 = $13.33
Seller share:
$13.33 x 45 = $599.85
Answer: $599.85, or $600 if rounded to the nearest dollar.

Common Mistakes
Mistake 1: Taxing The Appraised Value Before Exemptions
If the question gives an exemption, subtract it before applying the tax rate.
Wrong:
$400,000 x 0.02
Right, if there is a $50,000 exemption:
($400,000 - $50,000) x 0.02
Mistake 2: Treating Mills Like Percent
30 mills is not 30%.
30 mills means:
30 / 1,000 = 0.03 = 3%
Mistake 3: Mixing Rate Formats
These are equivalent:
2% = 20 mills = $2.00 per $100
But the calculation setup changes:
Value x 0.02
Value x 20 / 1,000
Value / 100 x 2.00
Mistake 4: Assuming A Texas State Property Tax
Texas has no state property tax. Local taxing units set property tax rates. Use the facts in the question and do not invent a statewide rate.
Mistake 5: Forgetting Multiple Taxing Units
A property may be taxed by more than one local taxing unit. If the question gives multiple rates, combine them or calculate each one as instructed.
Mistake 6: Guessing Proration Rules
Do not guess 360 or 365 days. Pearson says the question will specify the day-count basis and whether the closing day belongs to the buyer or seller.
Mistake 7: Adding Real-World Exemptions Not Given
Do not add a homestead exemption, age 65 exemption, local option exemption, or other exemption unless the question gives it.
Exam math uses the stated facts.

FAQ
How do you calculate property tax for real estate exam math?
Find taxable value first, then multiply by the tax rate. If the problem gives an exemption, subtract it from the value before applying the rate.
What is a mill rate?
A mill rate expresses tax as dollars per $1,000 of value. One mill equals $1 of tax per $1,000 of taxable value.
How do you calculate tax using mills?
Use taxable value x mills / 1,000. For example, $200,000 at 30 mills is $200,000 x 30 / 1,000, which equals $6,000.
Is 30 mills the same as 30%?
No. 30 mills equals 3%, because 30 / 1,000 = 0.03.
How do exemptions affect property tax math?
Exemptions reduce the taxable value. For exam math, subtract the exemption before applying the tax rate, unless the question says the value is already taxable value.
Does Texas have a state property tax?
No. The Texas Comptroller states that Texas has no state property tax. Local taxing units set rates and collect property taxes for local services.
Who appraises property for Texas property tax?
The Texas Comptroller explains that appraisal districts appraise taxable property within their county boundaries, generally at market value as of Jan. 1, subject to exceptions and local procedures.
Should I memorize Texas homestead exemption amounts for exam math?
For math questions, use the exemption amount given in the question. Texas exemption amounts and eligibility rules can change, and local option exemptions vary. This article is exam prep, not tax advice.
How do property tax prorations work?
Find annual tax, divide by the stated day count, then multiply by the number of days assigned to the buyer or seller. Pearson's math notes say the question will specify whether to use 360 or 365 days and who gets the closing day.
