TL;DR

In Texas, property taxes are local taxes — there is no state property tax. Each property is taxed by several overlapping taxing units (school district, county, city, and special districts), and the bill is calculated by multiplying the property's taxable value by each unit's tax rate. The residence homestead exemption reduces that taxable value for a property the owner uses as a principal residence — it does not lower the appraised market value, it lowers the value the tax is calculated on. The general residence homestead exemption currently removes $140,000 from the value taxed by school districts (the amount is set by the Texas Tax Code and has been increased by the Legislature and voters over time). On top of it, taxing units may offer optional local exemptions, and homeowners who are age 65 or older or disabled qualify for an additional school-district exemption and a school tax ceiling that freezes the school portion of their bill. A separate protection, the homestead cap, limits how much a homestead's taxable value can rise to 10% per year. To claim the exemption, the owner files an application (Form 50-114) with the county appraisal district; once granted it generally renews automatically. An owner may claim a homestead exemption on only one property.

How Property Tax Works in Texas

Texas has no state income tax and no state property tax. Property taxes are assessed and collected entirely at the local level, and they are the primary way Texas funds public schools, county government, cities, and special districts. Understanding the homestead exemption first requires understanding the three moving parts of a property tax bill.

The first part is the appraisal. Each county has an appraisal district — a separate governmental body whose job is to determine the market value of every property in the county as of January 1 each year. The appraisal district does not set tax rates and does not collect taxes; it only values property and administers exemptions.

The second part is the taxing units. A single property typically sits within several overlapping jurisdictions, each of which levies its own tax: the independent school district, the county, often a city, and sometimes special districts such as a municipal utility district (MUD) or a hospital or community college district. Each taxing unit adopts its own tax rate each year.

The third part is the calculation. The tax owed to each unit is the property's taxable value multiplied by that unit's tax rate. (Taxable value attaches to the property itself, whoever holds it — ownership passes by deed, but the tax obligation stays with the parcel.) Add the amounts from every taxing unit, and that is the annual property tax bill. The key term is taxable value — and that is exactly what the homestead exemption changes.

What a Homestead Exemption Actually Does

A residence homestead exemption removes a portion of a home's value from taxation. This is the single most important concept to get right, because the exam tests it directly: an exemption does not reduce the property's appraised market value. The appraisal district still appraises the home at its full market value. What the exemption does is reduce the taxable value — the figure the tax rate is actually applied to.

An example makes the mechanism clear. Suppose a home is appraised at $300,000 and qualifies for a school-district homestead exemption. The school district does not tax the full $300,000; it taxes $300,000 minus the exemption amount. The appraised value on the records is still $300,000 — but the school taxes are calculated as if the home were worth less. Because school-district taxes are usually the largest single piece of a Texas property tax bill, an exemption applied to school-district value produces meaningful savings.

Note that different exemptions apply to different taxing units. The general homestead exemption's main effect is on school-district taxes. Counties, cities, and other units may or may not offer their own homestead exemptions, and where they do, those are separate amounts. So a single home can have its taxable value reduced by different amounts for different lines on the tax bill.

The General Residence Homestead Exemption

The general residence homestead exemption is the baseline benefit available to any qualifying homeowner. The Texas Tax Code requires every school district to exempt a set dollar amount of a qualifying residence homestead's value from school-district taxation. That dollar amount is fixed by statute, and the Texas Legislature — at times with voter approval through constitutional amendments — has raised it over the years. The general residence homestead exemption currently removes $140,000 of a qualifying residence homestead's value from school-district taxation, under Texas Tax Code Section 11.13(b). The exam may focus more on the mechanism — the exemption reduces taxable value, not appraised value — but because $140,000 is current law, candidates should recognize it and verify the figure with the Texas Comptroller if studying from older materials, since the amount is set by statute and can change.

To qualify for the general residence homestead exemption, three conditions must be met. The applicant must have an ownership interest in the property (even partial ownership can qualify). The property must be the applicant's principal residence. And the applicant may not claim a homestead exemption on any other residence, in Texas or anywhere else — a person gets one homestead. A "residence homestead" in Texas can include the home plus up to 20 acres of land used for residential purposes.

Optional Local Exemptions

Beyond the school-district general exemption, any taxing unit — a county, a city, a special district — may choose to offer its own optional local homestead exemption. Where a taxing unit adopts one, it is typically expressed as a percentage of the home's appraised value rather than a flat dollar amount. A 20% local exemption on a $200,000 home, for instance, would reduce the value taxed by that unit to $160,000. These optional exemptions vary widely from one jurisdiction to the next, which is why two otherwise identical homes in different cities or counties can have noticeably different tax bills. Because they are optional and local, a homeowner should check with the county appraisal district to learn which exemptions apply to their specific property.

Additional Exemptions for Seniors and Disabled Homeowners

Texas provides enhanced protection for homeowners who are age 65 or older or who have a qualifying disability. Two separate benefits apply.

The first is an additional school-district exemption. A homeowner who is 65 or older, or who is disabled, receives an additional $60,000 school-district residence homestead exemption on top of the general exemption, under current Tax Code Section 11.13(c). Because exemption amounts can change, always verify current dollar figures with the Texas Comptroller or the county appraisal district. A homeowner who is both over 65 and disabled generally cannot claim both additional exemptions from the same taxing unit — they choose the one that gives the larger benefit.

The second, and often more valuable over time, is the school tax ceiling, sometimes called the senior tax freeze. In the year a homeowner qualifies (turning 65, for example), the school-district portion of their tax bill is frozen at that year's dollar amount. The home's appraised value can keep rising in later years, but the school taxes stay locked at the ceiling. The ceiling only moves upward if the owner makes significant improvements that add value, such as building an addition. A surviving spouse who is at least 55 may be able to keep a deceased spouse's over-65 ceiling if they continue to live in the home. Note the distinction the exam may test: the tax ceiling freezes the school tax amount; it does not freeze the appraised value.

The Homestead Cap on Appraised Value Increases

A separate protection — distinct from the exemptions above — is the homestead cap, also called the 10% appraisal cap. For a property with a homestead exemption, the cap limits how fast the value used to calculate taxes can climb. Beginning in the second year a homeowner has the homestead exemption, the taxable value generally cannot increase by more than 10% per year, regardless of how fast the market value is rising. The cap does not count value added by new improvements — if the owner adds a pool or a room, that new value is added on top of the capped figure. In a fast-appreciating market, the homestead cap can shield a homeowner from large year-over-year tax increases that an uncapped property would face. The cap is one more reason the homestead exemption matters beyond the immediate dollar reduction.

Applying for the Exemption

The homestead exemption is not automatic — the homeowner must apply. The application is filed with the county appraisal district where the property is located, using the Texas Comptroller's Form 50-114, Application for Residence Homestead Exemption. Applying is free. Once the exemption is granted, it generally renews automatically each year for as long as the owner continues to own and occupy the home as a principal residence — there is no need to reapply annually. A homeowner who turns 65 or becomes disabled files to add the additional exemption. Texas also allows late applications within a limited window, so an owner who missed the deadline can often still claim the exemption retroactively for a prior year. Because deadlines and optional local exemptions vary by county, the appraisal district is the authoritative source for a specific property.

The exemption follows the property owner's principal residence, not the owner from house to house automatically. When a homeowner sells one home and buys another, they file a new Form 50-114 with the appraisal district for the new property. The mechanics of property tax also intersect with closing — at the sale of a property, the year's taxes are typically prorated between buyer and seller so each pays for the portion of the year they own the home.

How This Topic Is Tested

Homestead and property tax questions on the Texas real estate exam concentrate on a few patterns. First, the core mechanism: a question describes an exemption and asks what it reduces — the answer is taxable value, not appraised market value. Second, qualification: scenarios testing the three requirements (ownership interest, principal residence, only one homestead). Third, the senior and disabled benefits: distinguishing the additional exemption (a dollar reduction) from the school tax ceiling (a freeze on the tax amount, not the value). Fourth, the homestead cap: knowing it limits taxable-value increases to 10% per year and does not apply to new improvements. Fifth, process: that exemptions are filed with the county appraisal district, not the taxing units or a lender, and that the appraisal district values property while taxing units set rates.

A reliable way to handle these questions: keep the three roles straight — the appraisal district values property and administers exemptions, the taxing units adopt tax rates and levy the tax, and the exemption reduces taxable value. Most homestead questions resolve once those roles are clear.

Common Misconceptions

  1. "A homestead exemption lowers your home's appraised value." False. The appraisal district still appraises the home at full market value. The exemption reduces the taxable value — the figure the tax rate is applied to — not the appraised value.
  2. "Texas has a state property tax." False. There is no state property tax in Texas. Property taxes are entirely local, levied by school districts, counties, cities, and special districts.
  3. "The senior tax ceiling freezes your home's value." False. The over-65 school tax ceiling freezes the dollar amount of school-district tax. The home's appraised value can still rise; the ceiling caps the tax, not the value.
  4. "The homestead exemption applies automatically when you buy a home." False. The homeowner must file an application (Form 50-114) with the county appraisal district. Once granted, it then renews automatically, but the initial application is required.
  5. "You can claim a homestead exemption on more than one property." False. A person may claim a residence homestead exemption on only one property — their principal residence — in Texas or anywhere else.

Bottom Line

Texas property tax is local: a property's bill is its taxable value times the tax rate of each overlapping taxing unit, with no state property tax involved. The residence homestead exemption reduces taxable value — not appraised market value — for an owner's principal residence, with the general exemption applying mainly to school-district taxes and optional local exemptions varying by jurisdiction. Homeowners who are 65 or older or disabled get an additional school-district exemption and a tax ceiling that freezes the school tax amount, and the homestead cap limits taxable-value increases to 10% per year. The exemption requires filing Form 50-114 with the county appraisal district and is limited to one property per owner. On the exam, keep the roles straight: the appraisal district values, taxing units set rates, and the exemption cuts taxable value. From here, the natural next topics are how title insurance protects an owner's interest and the disclosures a seller must make.

Frequently Asked Questions

Does a homestead exemption lower my home's value?
No. A homestead exemption does not change your home's appraised market value — the appraisal district still appraises it at full value. The exemption reduces the taxable value, which is the figure the tax rate is multiplied by to calculate your bill. Your appraised value stays the same; the value your taxes are calculated on goes down.
Who qualifies for the general residence homestead exemption in Texas?
To qualify, you must have an ownership interest in the property (partial ownership can count), use the property as your principal residence, and not claim a homestead exemption on any other property in Texas or another state. A residence homestead can include the home plus up to 20 acres used for residential purposes.
What extra benefits do homeowners 65 or older receive?
Homeowners who are 65 or older receive two benefits: an additional school-district exemption amount on top of the general homestead exemption, and a school tax ceiling that freezes the dollar amount of their school-district taxes in the year they qualify. The ceiling caps the tax amount even as the home's value rises; it only increases if significant improvements are added. Disabled homeowners qualify for similar benefits.
What is the homestead cap?
The homestead cap, also called the 10% appraisal cap, limits how much the taxable value of a homestead property can increase each year. Beginning in the second year you hold the homestead exemption, the taxable value generally cannot rise more than 10% per year, regardless of market appreciation. Value added by new improvements is not subject to the cap and is added on top.
How do I apply for a homestead exemption?
You apply by filing Form 50-114, Application for Residence Homestead Exemption, with the county appraisal district where the property is located. Applying is free. Once the exemption is granted, it generally renews automatically each year as long as you continue to own and occupy the home as your principal residence. Texas also allows late applications within a limited window for prior years.
What is the difference between the appraisal district and the taxing units?
The county appraisal district determines the market value of each property and administers exemptions — it does not set tax rates or collect taxes. The taxing units (school district, county, city, special districts) each set their own tax rate and levy taxes. Your bill is the taxable value of your property multiplied by the combined rates of all the taxing units it falls within.
