Texas is one of the few large states with no personal income tax. That policy choice has a direct cost: local governments — cities, counties, school districts, and special districts — rely almost entirely on property taxes to fund roads, courts, schools, and public safety. The result is that Texas homeowners face some of the highest effective property tax rates in the nation, typically ranging from 1.5% to 2.5% of home value, depending on location.
Understanding how Texas property taxes work — how values are set, which exemptions are available, and how to fight an assessment you believe is wrong — is essential knowledge for any Texas homeowner. This guide covers the full picture.
How Texas Property Taxes Work: Two Separate Functions
In Texas, property taxation involves two distinct entities: the appraisal district and the taxing entities. Confusing the two is the most common source of misunderstanding about the system.
Each county has a central Appraisal District (CAD) — such as the Harris County Appraisal District (HCAD) or the Travis Central Appraisal District — responsible solely for determining the market value of every property in the county. The appraisal district does not set tax rates and does not collect taxes. Its only job is to appraise.
Taxing entities — your school district, county, city, community college district, hospital district, and any special districts — independently set their own tax rates each fall, expressed in dollars per $100 of taxable value. Your total tax bill is the sum of each entity's rate applied to your taxable value. A home in suburban Houston might be subject to eight or more separate taxing entities.
The Homestead Exemption: Your Biggest Tax Break
Important
The homestead exemption is never applied automatically when you buy a home. Even if the previous owner had it, you must file a new application with the county appraisal district. The exemption applies only to properties you own and occupy as your primary residence on January 1 of the tax year.
The most important exemption available to Texas homeowners is the homestead exemption, which applies only to a property you own and occupy as your primary residence. As of 2023, House Bill 2 raised the mandatory school district homestead exemption from $40,000 to $100,000 off the appraised value.
What this means in practice: if your home is appraised at $350,000 and you have the homestead exemption, your school district taxes are calculated on only $250,000 of value. At a typical school district rate of $1.00 per $100, that is a savings of $1,000 per year on school taxes alone.
Cities and counties can also grant optional homestead exemptions of up to 20% of appraised value (minimum $5,000). Many Texas cities and counties offer these additional exemptions. To benefit, you must file an application with your county appraisal district. The deadline is April 30 of the tax year for which you are claiming the exemption. Once granted, the homestead exemption renews automatically as long as you continue to occupy the property.
The 10% Annual Appraisal Cap
One of the most powerful protections in Texas property tax law is the 10% annual cap on appraisal increases for homestead properties. Once you have a homestead exemption in place, the appraised value used for tax calculations cannot increase by more than 10% per year — regardless of how much the actual market value of your home has risen.
This cap applies to the taxable appraised value, not the market value the appraisal district estimates. The district can increase its market value estimate by 30%, 50%, or any amount — but your taxable value cannot jump more than 10% in a single year.
The practical effect is significant in rapidly appreciating markets. A home purchased for $300,000 in 2019 with a homestead exemption and a market value that rose to $600,000 by 2023 would still have a taxable appraised value capped well below $600,000 — even if the appraisal district correctly identified the new market value. This built-in lag keeps tax bills from doubling or tripling in hot markets.
Non-homestead properties — investment properties, vacation homes, commercial real estate — do not receive the 10% cap and can be reassessed to full market value in a single year.
School District Rates: The Biggest Line on Your Bill
Note
Your total Texas tax bill is the sum of all taxing entity rates — school district, county, city, community college, hospital district, and any special districts — applied to your taxable appraised value. School taxes are typically the largest single component.
School district taxes typically account for 50% to 60% of a Texas homeowner's total property tax bill. Understanding your school district's rate is therefore the most important factor in understanding your overall tax burden.
Texas school district tax rates are expressed in dollars per $100 of taxable value and consist of two components: the Maintenance and Operations (M&O) rate that funds day-to-day school operations, and the Interest and Sinking (I&S) rate that services bond debt approved by voters for construction and facilities. The two rates are added together to get the total school district rate.
The Texas Education Agency publishes school district tax rates annually. For the 2023 tax year, total school district rates for most districts ranged from $0.85 to $1.25 per $100 of taxable value, after state compression programs reduced M&O rates. Some districts with heavy bond debt have higher combined rates. To find your specific district's current rate, search the Texas Comptroller's school district property value study database or your county appraisal district's website.
Senior and Disability Freeze: Locking In Your School Taxes
Texas offers one of the most valuable senior property tax protections in the nation: a school tax ceiling for homeowners age 65 and older. Once you reach age 65 and apply, your school district property taxes are frozen at the level they were the year you first qualified. Even if school tax rates rise or your property value increases, you will never pay more in school district taxes than that frozen amount.
The senior freeze does not apply to county, city, or other taxes — only school district taxes. But since school taxes are typically the largest component of the bill, the savings over time can be substantial. The freeze remains in place as long as you own and occupy the property.
An additional $10,000 exemption on the school district assessed value (on top of the standard $100,000 homestead exemption) is also available for homeowners 65 and older. Homeowners with a disability (as defined under federal law) are entitled to the same exemptions and freeze rights as seniors. You cannot claim both the over-65 and disability exemptions simultaneously, but you may claim whichever provides greater benefit.
How to Protest Your Appraisal
Tip
You do not need an attorney or consultant to file a Texas property tax protest. Many homeowners successfully protest on their own using publicly available sales data from Zillow, Redfin, or the county appraisal district's own sales database.
Every Texas property owner has the right to protest their appraised value annually. You protest to the Appraisal Review Board (ARB) — an independent panel separate from the appraisal district — not to the taxing entities. You are protesting the value the appraisal district assigned, not the tax rate.
The standard deadline to file a notice of protest is May 15 of the tax year, or 30 days after the appraisal district mailed your notice of appraised value — whichever is later. Filing is free and can usually be done online through your county appraisal district's portal.
Most counties offer an informal hearing before the formal ARB hearing. In the informal hearing, you meet directly with an appraisal district staff member and present your evidence. Many protests are resolved at this stage. If you cannot agree, you proceed to a formal ARB panel hearing.
- Comparable sales (comps): Find 3–5 recent sales of similar homes in your neighborhood. Sales within the last 6–12 months carry the most weight. The appraisal district must consider evidence you present.
- Property record card errors: Request your property record card from the district. Check the square footage, bedroom count, lot size, year built, and condition rating. Errors in these inputs can cause significant overvaluation.
- Unequal appraisal: Texas law allows you to protest if your property is appraised higher than comparable properties, even if the absolute value is defensible. This "equity" protest can be very effective.
- Damage or condition issues: Photos and repair estimates documenting deferred maintenance, foundation issues, or damage that reduces market value.
Texas vs. the National Picture
Texas property taxes are high by national standards. The statewide average effective rate is consistently among the top five in the nation — typically between 1.6% and 1.9% of home value for owner-occupied properties. This reflects the structural reliance on property taxes in the absence of a state income tax.
In exchange, Texas residents pay no state income tax, and Texas has no state capital gains tax. Whether the trade-off is favorable depends on your income and spending patterns. For high-income earners, the lack of state income tax more than offsets the property tax burden. For lower-income homeowners with modest incomes but high property values, the property tax can be a genuine hardship — which is why the exemptions and protest process described in this guide are so important to understand.
