A property tax increase in Texas is governed by a stack of caps and exemptions, but those limits only protect what is already on your record.
- The 10% homestead cap and 20% circuit breaker limit how much taxable value can climb each year, with very different rules
- November 2025 constitutional amendments raised the school district homestead exemption to $140,000 and added $60,000 more for seniors and disabled homeowners, retroactive to January 1, 2025
- Caps work on the back end, but only a protest can lower the tax appraised value those caps protect
- The 2026 protest window closes May 15 in most Texas counties
If your 2026 notice arrived this spring, the smartest move is to file a protest now and sort out the strategy after the deadline is locked in.
Notices of Appraised Value have already gone out across most of Texas, and the numbers are landing differently from county to county. Travis Central Appraisal District released 2026 market values showing a 1.8% average drop for single-family homes, while El Paso saw average market values rise about 3%. Whether your number went up, sideways, or down, the same rule applies: a property tax increase in Texas is governed by a layered system of caps, exemptions, and statutory limits.
The Texas property tax system builds that protection in three layers: a 10% annual cap for primary residences, a temporary 20% circuit breaker for most other real property, and a refreshed set of exemptions retroactive to 2025. The caps protect what is on your record. A protest filed before May 15 challenges what gets recorded.
How Does the Limit on Property Tax Increase in Texas Actually Work?
The most common protection is the residence homestead cap. Texas Tax Code Section 23.23 limits the annual increase to a homestead’s taxable value to no more than 10% above the previous year’s value, plus the value of any new improvements. The cap does not kick in immediately. It takes effect on January 1 of the tax year following a full base year of homestead qualification, which means the cap typically does not apply until the second year a homeowner has lived in the property with an active homestead exemption.
The cap does not change your tax appraised value. The county appraisal district still sets that number based on what your property would sell for on January 1, and limits how much of it is used to calculate your tax bill. The gap between the tax appraised value and the lower assessed value is your homestead cap loss.
Picture a home in a fast-growing Austin neighborhood. The tax appraised value rises from $400,000 to $500,000 in a single cycle. With an active homestead exemption and the 10% cap in place, the assessed value can only climb to $440,000. Over five years in an appreciating market, the gap can grow into six figures.
What Changed in 2025 That Reshapes Texas Property Tax Increase Protection?
Texas voters reshaped the exemption side in November 2025. According to Ballotpedia’s 2025 ballot measures coverage, all 17 constitutional amendments passed. Three matter most for the 2026 cycle:
- Proposition 13: Raised the school district homestead exemption from $100,000 to $140,000
- Proposition 11: Increased the additional exemption for homeowners 65 and older or disabled from $10,000 to $60,000, creating a combined $200,000 in exempt value
- Proposition 9: Raised the business personal property exemption from $2,500 to $125,000
A critical detail many homeowners miss: these increases are retroactive to January 1, 2025, so the new amounts apply to 2025 tax bills paid this year. The Texas Tribune reported the property tax measures passed by comfortable margins, locking in the largest slate of property tax relief in state history.
These changes amplify the cap. The cap limits how fast taxable value grows; the exemption decides how much value gets removed before school district taxes are calculated. Both rely on Form 50-114, filed with your county appraisal district. Under SB 1801, counties verify homestead exemptions every five years, so respond promptly to any verification request to keep yours active.
What Is the Circuit Breaker Cap, and Who Qualifies in 2026?
The 10% homestead cap protects primary residences. A different protection covers almost everything else. Tax Code Section 23.231 created the “circuit breaker” limitation, which caps the annual increase in tax appraised value at 20% for qualifying real property that is not a homestead.
For 2026, the threshold is $5,320,000 or less, as confirmed by the Texas Comptroller. That figure rises with the consumer price index each year. The 2024 threshold was $5,000,000, and 2025 was $5,160,000.
A few important rules:
- It applies automatically, no application required
- It does not apply to homestead property, agricultural or timberland, recreation parks, scenic land, or public access airport property
- The owner must hold the property for one full calendar year before the cap takes effect
- The cap currently expires December 31, 2026, unless the Legislature renews it
Investment property owners, second-home owners, and small commercial owners should check whether the 20% circuit breaker is being applied correctly to their 2026 notice. With the program scheduled to sunset at year-end, this could be the last cycle the limit operates as automatic protection.
Why Tax Appraised Value Versus Assessed Value Matters
The difference between tax appraised value and assessed value is one of the most misunderstood concepts in the system. The Texas Property Tax Code requires all taxable property to be valued at 100% of market value as of January 1, and that figure becomes your tax appraised value. The assessed value is what is left after exemptions and any cap are applied; that is the number actually used to calculate your tax bill.
Two homes on the same street can share an identical $500,000 tax appraised value. The home with an active homestead exemption and several years of cap protection might have an assessed value of $400,000, while the home next door pays taxes on the full $500,000. That gap compounds every year the market appreciates faster than 10%.
The gap is invisible until something disrupts it. If a homeowner moves, converts the property to a rental, or transfers title to an LLC or trust, the cap evaporates and taxes jump to the full tax appraised value. That is why protesting matters even when the cap is keeping your taxable value low.
What Texas Property Tax Increase Limits Cannot Protect You From
The caps have several blind spots:
- Tax rate increases. Caps limit how much taxable value can grow, but local taxing entities can still raise rates within the limits the law allows.
- New improvements. Building an addition, finishing a basement, adding a detached garage, installing an in-ground pool, or doing a garage conversion all add value on top of the capped amount. Routine kitchen and bathroom remodels don’t always change the appraisal, but they can if a permit was filed.
- Loss of homestead status. The moment a property stops qualifying as your primary residence, the cap disappears, and the assessed value resets to the full tax appraised value.
- An inflated tax appraised value. The cap controls the increase, but if your starting tax appraised value was too high, the cap protects an inflated number.
That last point is what most homeowners overlook. If your 2026 tax appraised value is wrong on its face, no cap will fix it. Only a properly prepared protest of that number, whether you handle it yourself or work with licensed local property tax professionals, will reduce it.
How to Use the May 15 Deadline to Your Advantage
The 2026 protest deadline in most Texas counties is May 15. Under Texas Tax Code Section 41.44, it is the later of May 15 or 30 days after the appraisal district mailed your Notice of Appraised Value, and the date printed on the notice itself is the only one that matters. Miss it, and your right to protest the 2026 tax appraised value is gone for the year.
Filing on time is the only thing that has to happen this week. The hearing, evidence exchange, and any informal settlement conversations can play out over the following months, and most appraisal districts now allow electronic filing. If you plan to work with licensed local property tax professionals, sign up before submitting protest paperwork so the same team can take the case all the way through.
Once filed, the evidence that moves the needle is comparable sales for similar properties and contractor estimates for repair or replacement costs. The 12-month window leading up to January 1 is the relevant timeframe for sales comparisons. The Appraisal Review Board cannot consider whether your taxes feel too high in general; the case has to be specifically about whether your tax appraised value reflects what your home would have sold for on January 1, 2026.
Common Misconceptions About Property Tax Increase Limits in Texas
A few assumptions trip up Texas homeowners most often.
The cap will protect me from any tax increase
A 10% cap on taxable value is generous, but compounding 10% annual increases can double your taxable value in roughly seven years. Tax rates are set independently by local taxing entities, so your bill can rise even when your taxable value does not. The cap is a brake, not a freeze.
My tax appraised value does not matter if my cap is in place
This is one of the costliest assumptions a homeowner can make. The tax appraised value is the number waiting in the wings the moment exemption status changes. Letting it climb unchallenged is the same as building a future tax cliff for yourself or a future buyer.
Protesting is not worth it when my cap is in place
Annual protesting is worthwhile regardless of how the numbers look in any given year, and protesting every year is the only way to confirm your tax appraised value is fair. A reduction lowers the recorded number, which lowers the baseline future cap calculations build from. Even years that produce no reduction answer the underlying question, and no licensed property tax professional in Texas can lawfully promise a specific reduction. What licensed local property tax professionals can do is take the case all the way through every step of the process so the answer is real.
Frequently Asked Questions
A few questions come up most often during protest season.
When does the homestead cap take effect after I buy a home?
The cap requires a base year. After a homeowner qualifies for the homestead exemption, they need one full calendar year of homestead occupancy before the 10% cap takes effect on January 1 of the following tax year. In practice, that means the cap usually does not apply until the second year of ownership, and a homeowner who qualifies in 2026 generally sees the cap take effect for the 2027 tax year. During that uncapped first stretch, the tax appraised value can climb freely, which is why the first protest a new owner files is one of the most consequential.
Does the circuit breaker apply if I own my rental property through an LLC?
The circuit breaker applies based on property type and value, not ownership structure. Non-homestead real property valued at $5,320,000 or less in 2026 generally qualifies, whether title is held individually, jointly, or by an entity.
What happens to the cap when I sell my home?
The cap resets at sale. The new owner starts at the full tax appraised value with no cap protection. Once they qualify for their own homestead exemption and complete a full base year of occupancy, the cap takes effect on January 1 of the following year, typically the second year of their ownership. The previous owner’s accumulated cap loss does not transfer.
Can the over-65 school tax freeze stack with the cap?
Yes. Homeowners 65 and older receive both the 10% cap and a school district tax freeze, frozen at the lower of the amount paid the year the homeowner turns 65 or the following year, per the Texas State Law Library’s overview. The freeze applies only to school district taxes.
Take Action Before May 15 to Lock In Your Protections
Texas property tax increase limits are powerful, but they only work as well as the tax appraised value sitting underneath them. A 10% cap on an inflated number is still a cap on an inflated number. The homestead exemption removes value from school district taxes, and the circuit breaker holds non-homestead increases to 20%, but neither one challenges what the appraisal district decided your property is worth on January 1.
The protest window for 2026 closes May 15. Filing does not commit you to anything beyond preserving your right to a hearing, and your tax appraised value cannot legally be increased as a result.
