The Power of the 20% Local Option Homestead
While the $140,000 school district exemption is mandatory across the entire state, your city, county, or special district (like a hospital or flood control district) has the legal authority to offer a Local Option Homestead Exemption. Under Tax Code Section 11.13(n), any taxing unit can choose to exempt up to 20% of your home’s appraised value, with a minimum exemption of $5,000. For a homeowner in a high-value area like Austin or Dallas, this 20% “off the top” can often be more valuable than the flat school district credit.
In 2026, major hubs have leaned heavily into this. For instance, both Harris County and the City of Houston offer the full 20% local option. If your home is appraised at $500,000, these units don’t tax you on $500,000; they subtract $100,000 (20%) and tax you only on $400,000. Because this is a percentage-based savings, as your property value rises, the dollar value of your “Texas Tax Savings” grows automatically alongside it, providing a natural hedge against inflation.
Massive Senior Bonuses: The $229,000 Harris County Shield
One of the most startling examples of local generosity is found in Harris County (Houston). While the state requires school districts to give seniors an extra $60,000 exemption, Harris County and the Harris County Flood Control District have historically opted to provide an eye-popping $229,000 exemption for residents aged 65 or older or those with disabilities.
This means that if you are a senior living in Houston with a $300,000 home, you pay almost nothing in county-level taxes. When you combine this with the $200,000 total school district exemption ($140k general + $60k senior), it is entirely possible for a Texas senior to own a $250,000 home and have a total property tax bill of nearly zero.
These “Local Option” amounts are not standardized; while Harris County offers $229,000, the City of Dallas or Bexar County (San Antonio) may offer significantly different amounts, such as $100,000 or a percentage-based cap. Always check your specific taxing unit’s “Exemption Chart” on your Appraisal District’s website to ensure you aren’t leaving six figures of protection on the table.
Taxing Unit Appraised Value Exemption Type Taxable Amount
School District $500,000 $140,000 (State) $360,000
Harris County $500,000 20% (Local Option) $400,000
City of Houston $500,000 20% (Local Option) $400,000
The 2026 “Prop 2” Win for Child-Care Facilities
A brand-new localized benefit for the 2026 tax year is the Child-Care Facility Exemption (Proposition 2). Texas now allows cities and counties the option to offer a property tax exemption of at least 50% (and up to 100%) of the appraised value of a property used to operate a qualifying child-care facility.
To qualify for this massive “Texas Tax Savings,” the facility must participate in the “Texas Rising Star” program and ensure that at least 20% of its enrolled children receive subsidized services. In major metropolitan areas like Harris County, the Commissioners Court has already moved to adopt a 100% exemption. This is a rare instance where the tax savings are designed to be “passed through”—if a child-care center rents its building, the property owner is legally required to pass the tax savings directly to the center in the form of lower rent.
Disaster Exemptions: Temporary Relief for 2026 Storms
Texas is no stranger to extreme weather. If your home or business was physically damaged by a governor-declared disaster (such as the severe storms and flooding seen in early 2026), you may qualify for a Section 11.35 Temporary Disaster Exemption. This provides a “rating-based” reduction in your property’s value for the remainder of the year:
-
Level 1 (Minimal damage): 15% exemption
-
Level 2 (Non-structural damage): 30% exemption
-
Level 3 (Significant structural damage): 60% exemption
-
Level 4 (Total loss): 100% exemption
This relief is not automatic. You must apply within 105 days of the governor’s disaster declaration. It serves as a vital bridge, lowering your tax burden while you are spending capital on repairs and reconstruction.

Final Audit: How to Verify Your 2026 Savings
The “Final Step” in your 2026 tax journey is the October Audit. When your final tax bill arrives in the mail, do not just look at the “Total Due.” Look at the Exemption Codes.
-
HS: General Homestead
-
65 / OV65: Over 65 Exemption
-
DP: Disabled Person
-
DV: Disabled Veteran (often followed by a number like DV4 for 100%)
If any of these codes are missing from a specific taxing unit (like your city or your MUD), you have a “Gap in Coverage.” Because Texas allows for late applications, you can often go back and fix these errors, resulting in a corrected bill or a refund check.
Frequently Asked Questions (FAQs)
Q: What is a “Local Option” exemption in Texas?
A: Unlike state-mandated school exemptions, a “Local Option” is a choice made by your city or county to offer additional tax relief—up to 20% of your home’s value or a specific dollar amount for seniors.
Q: Does every county in Texas offer the 20% local homestead exemption?
A: No. Each taxing unit (City, County, MUD) decides individually. Major hubs like Harris County and the City of Houston offer the full 20%, but smaller districts may offer less or none at all.
Q: How much is the Harris County senior exemption for 2026?
A: Harris County has one of the most generous protections in the state, offering a $320,000 exemption (combined with local options) for seniors aged 65+ and disabled residents.
Q: What is the “Prop 2” Child-Care Exemption?
A: Passed as a constitutional amendment, it allows cities and counties to exempt at least 50% (up to 100%) of the value of properties used as licensed child-care facilities. This is a new benefit for the 2026 tax year.
Q: Do I qualify for the Disaster Exemption (Section 11.35) in 2026?
A: If your property was damaged by a governor-declared disaster (like the 2026 storms), you can apply for a temporary exemption. The reduction ranges from 15% to 100% based on the severity of the damage.
Q: What is the deadline to apply for the Disaster Exemption?
A: You must file the application (Form 50-312) within 105 days of the governor’s disaster declaration.
Q: My tax bill has a code “HS.” What does that mean?
A: “HS” stands for General Residence Homestead. It is the most common code and indicates you are receiving the standard state and local homestead protections.
Q: Can a landlord benefit from the Child-Care exemption?
A: Yes, but the law requires the property owner to pass the savings to the child-care facility through lower rent or credits.
Q: What if I notice an exemption is missing on my October tax bill?
A: You can file a late application! Texas allows you to claim most homestead exemptions up to two years after the delinquency date. You may receive a corrected bill or a refund check.
Q: Is there an exemption for solar or wind-powered energy devices?
A: Yes. Under Section 11.27, you can apply for an exemption on the value these devices add to your property. It ensures your “green” upgrades don’t increase your tax bill.
