Understanding Property Tax Caps and Limitations in Texas
September 8, 2025
Property taxes can feel overwhelming, especially with rising property values across Texas. However, the good news is that Texas law provides certain protections to homeowners through property tax caps, known explicitly as homestead caps. If you’re a homeowner looking to understand how these caps work and their relationship with property tax protests, you’re in the right place.
What is the Homestead Cap?
Texas has implemented a “homestead cap,” which helps limit how much your property’s taxable value can increase annually. Specifically, Texas law caps the annual increase in assessed value at 10% for residential homesteads. However, there’s also a broader cap of up to 20% for all properties valued under $5 million, which adjusts annually based on inflation (Consumer Price Index – CPI). This means that even if your property’s market value skyrockets, the taxable assessed value won’t increase beyond these caps in a year.

How the Homestead Cap Protects You
Let’s simplify this with an example:
Suppose last year, your home’s assessed value was $300,000, but due to rising market values, this year the appraisal district assesses your home at $370,000—a significant increase. With the 10% homestead cap, your taxable assessed value is limited to $330,000 for this tax year, reducing your immediate property tax burden.
Understanding the 20% Cap for Other Properties
For properties valued under $5 million, a broader annual cap of up to 20% is adjusted annually for inflation (CPI). This cap helps stabilize property tax bills, which is particularly beneficial for small business owners or those owning rental properties.
How Property Tax Caps Affect Your Protest
Understanding how these caps interact with property tax protests is crucial. When you protest your property’s valuation, you’re challenging its market value, not the capped taxable value. Winning your protest and lowering your property’s appraised market value can still be beneficial because it resets your baseline for future years, potentially reducing your tax burden long-term.
Even if you’re benefiting from the cap this year, successfully protesting to lower your market value can offer substantial savings by minimizing future taxable increases.

You can protest your property’s assessed value independently or hire a professional team to assist. Doing it yourself can seem cost-effective initially, but the property tax system in Texas is intricate. Without experience, the process can become daunting.
