Central Texas Property Taxes Explained

Property taxes are one of the biggest ongoing costs of homeownership in Texas. For homeowners in the Austin area, including communities like Cedar Park, Westlake and Lakeway—understanding how property taxes work can help you plan financially and avoid surprises when your tax bill arrives.

If you’ve ever wondered why your property taxes change each year or how your home’s value is determined, this guide will walk through the basics of the Texas property tax system and what it means for local homeowners. We've partnered with our local partner, Ownwell to bring you all the details.

Why Property Taxes Are Important in Texas

Texas operates differently from many other states because there is no state income tax. As a result, local governments rely heavily on property taxes to fund essential public services like schools, roads, emergency services, and parks. (Ownwell)

Your property tax bill helps support:

• Local school districts
  
  
• City services and infrastructure
  
  
• County operations
  
  
• Public safety departments
  
  
• Libraries and community programs
  
  

Because local services depend on property tax revenue, Texas property taxes tend to be higher than the national average.

Who Determines Your Property Value?

In Texas, property values are determined by county appraisal districts, not your city government and not the state.
Austin and surrounding, this typically means your property value is assessed by the Travis, Hays, or Williamson Central Appraisal District.

Appraisal districts estimate the market value of every property as of January 1 each year, which is the value used to calculate property taxes. (Texas Comptroller)

Market value represents what a property would reasonably sell for in an open market between a willing buyer and seller. (Texas Comptroller)

How Property Taxes Are Calculated in Texas

The formula used to calculate property taxes is relatively straightforward.

Step 1: Determine the property’s appraised value
Step 2: Subtract any exemptions
Step 3: Apply the local tax rate

The basic formula looks like this:

(Appraised Value − Exemptions) × Local Tax Rate = Property Tax Bill

Local tax rates are set by taxing entities such as school districts, cities, and counties. (Texas Comptroller)

For example:

Rates vary depending on the location and school district, which is why property taxes can differ significantly between neighborhoods around the Austin metro.

How Appraisal Districts Determine Property Value

Appraisal districts evaluate large numbers of properties each year using a process called mass appraisal. This method uses statistical models and market data to estimate the value of many homes at once. (Ownwell)

When determining a property’s value, appraisal districts often consider:

• Recent sales of comparable homes
  
  
• Property size and square footage
  
  
• Age of the home
  
  
• Location and neighborhood trends
  
  
• Improvements or renovations
  
  

Because Texas is a non-disclosure state, sales prices are not always publicly reported, which can make valuation estimates less precise. (Ownwell)

This is one reason property owners sometimes believe their home has been overvalued.

Property Tax Exemptions Available to Texas Homeowners

One advantage for homeowners in Texas is the availability of several tax exemptions that can reduce your taxable value.

Common exemptions include:

Homestead Exemption

The homestead exemption applies to your primary residence and reduces the taxable value of your home.

It also includes a valuable feature called the homestead cap, which limits how much your appraised value can increase each year for tax purposes—generally no more than 10% annually. (Ownwell)

Over-65 Exemption

Homeowners aged 65 or older may qualify for additional exemptions and, in some cases, a freeze on school district taxes.

Disabled or Veteran Exemptions

Texas offers additional tax relief for qualifying disabled individuals and veterans, including significant reductions and sometimes full property tax exemptions depending on disability status. (Texas Tax Appeal)

Applying for exemptions typically requires submitting forms to your local appraisal district.

Why Your Property Taxes May Increase

Many homeowners are surprised when their tax bill rises, even if they haven’t made major improvements to their property.

Common reasons include:

• Rising home values in your neighborhood
  
  
• Local tax rate changes
  
  
• Improvements or additions to your home
  
  
• Expiring exemptions or missed filings
  
  

In rapidly growing markets like Austin and surrounding suburbs, property values can shift quickly as demand increases.

Can You Challenge Your Property Value?

Yes—Texas homeowners have the right to protest their property appraisal if they believe the value assigned to their home is too high.

You can file a protest with your local Appraisal Review Board if:

• Your home’s value is higher than comparable sales
  
  
• The appraisal district has incorrect property details
  
  
• Your home’s condition differs from similar homes used for valuation
  
  

The typical deadline to file a protest is May 15 or 30 days after receiving your appraisal notice, whichever is later. (Ownwell)

Many homeowners review their valuations each year to ensure they are aligned with actual market conditions.

What This Means for Austin-area Homeowners

The Austin real estate market has seen significant price growth over the past decade, which has also led to rising property tax bills for many homeowners.

Understanding how the system works can help you:

• Plan for annual tax increases
  
  
• Make sure your exemptions are properly applied
  
  
• Evaluate whether a property tax protest might make sense
