Texas Just Cut Your Property Tax Bill: What Houston, Dallas, San Antonio, and Austin Homeowners Need to Know in 2026

If you own a home in Texas, your property tax bill is already smaller than it was before, and you probably don't need to do anything to get there. Proposition 13 (SB 4) passed on November 4, 2025. Because the vote passed in November 2025, appraisal districts recalculated taxable values retroactively to January 1, 2025, and tax bills already reflect the new $140,000 exemption. Homeowners do not need to take any action.

Texas voters approved Proposition 13 (SB 4) in November 2025, raising the school district homestead exemption to $140,000, up from $100,000, as part of what Governor Greg Abbott called "the largest property tax relief ever provided by any governor in American history," $51 billion in the last legislative session alone (Abbott's stated figure; independent analyses vary).

The savings hit automatically. If you already have a homestead exemption on file, the increase applies automatically. If you haven't filed yet, the process is free and one-time through your county appraisal district.

The Number That Matters

The $140,000 homestead exemption reduces your taxable value for school district taxes. School district levies are typically the largest single line item on a Texas property tax bill, so that reduction lands hard.

For homeowners who already had the prior $100,000 exemption on file, the most immediate headline is the incremental gain: the new $140,000 ceiling represents a $40,000 increase in exempt value. At a typical school district rate of 0.8%–1.0% (per Texas Comptroller published rate data), that additional $40,000 of relief saves existing homeowners roughly $320–$400 per year beyond what they were already receiving. In districts with rates above 1.0%, the incremental saving runs higher.

For new filers claiming the full $140,000 exemption, the savings are larger. For a $400,000 home, you pay school taxes only on $260,000 of value, saving roughly $1,120 to $1,400 per year across the typical school district rate range of 0.8%–1.0% (per Texas Comptroller published rate data; calculated as: exemption amount × school district rate). Austin ISD's current rate and Houston ISD's current rate both fall within this range. Check your county appraisal district or school district's published rate to verify the math for your specific address. In districts with rates above 1.0%, savings will exceed $1,400.

Seniors and disabled homeowners get an even bigger break: an extra $60,000 exemption on top of the standard amount, for a combined $200,000. This add-on was enabled by Proposition 11, while the standard exemption increase came from Proposition 13 (SB 4), both voter-approved in November 2025. Consult your county appraisal district to confirm eligibility rules for claiming both simultaneously.

What Abbott's Follow-On Plan Means for Buyers

The exemption increase is the headline, but the five-point follow-on plan Abbott announced in early 2026 is the bigger story for anyone doing long-term affordability math.

Abbott is proposing to cap annual appraisal growth at 3% and create a constitutional pathway for voters to eliminate school district taxes for homeowners entirely. His proposal would lower the cap on homestead appraisal increases from 10% per year to 3%, while also applying appraisal caps to all properties, including rental and commercial properties. The plan would also require appraisals once every five years instead of at least once every three years under current law, which Abbott says would make property taxes more predictable year-to-year.

None of this is law yet. Some economists and local government groups have raised concerns about the sustainability and unintended consequences of the proposed 3% appraisal cap, including potential shifts in tax burden, reduced local government revenues, and long-term distortions in the housing market. But if you're buying in Dallas or Austin today, a future 3% appraisal cap fundamentally changes the compounding cost of homeownership over a 10-year hold. Keep an eye on the 2027 legislative session.

The Competitive Picture Across Sun Belt Metros

Texas metros still carry above-average property tax rates compared to most of the country. Texas homeowners' combined nominal property tax rates, covering school district, county, city, and special district, often total 2% to 2.5% of appraised value, translating to an effective rate of roughly 1.4% to 1.6% of market value (Source: Tax Foundation, 2026; TaxDrop, 2026), well above the national average of under 1%.

That gap exists partly because Texas has no state income tax. You're paying for services somewhere. But compared to Sun Belt competitors like Phoenix and Nashville, where effective rates run significantly lower, the Texas premium is real and worth modeling before you commit to a price point.

For a relocator choosing between Austin and Charlotte, the property tax line alone can represent a meaningful difference in your monthly carrying cost. The Austin vs Charlotte cost-of-living comparison is a good place to run those numbers side by side.

The Investor Carve-Out You Need to Know

If you own rental property in Texas, this exemption doesn't help you. Only your primary residence qualifies. No second homes, rentals, or LLC-owned properties are eligible. The relief is targeted specifically at owner-occupants.

That's a meaningful asymmetry. A landlord in Houston with a portfolio of rentals sees no direct benefit from the homestead increase, while their owner-occupant neighbor does. If you're evaluating a Texas investment property on a projected net-operating-income basis, the $140,000 homestead exemption changes nothing for your math.

For the Two of You Making This Decision

If the data-minded half of your household wanted the numbers, there they are: a $140,000 exemption retroactive to the 2025 tax year, saving existing homeowners roughly $320–$400 per year from the incremental $40,000 increase, and up to $1,120–$1,400 per year for new filers claiming the full exemption on a mid-range Texas home. A follow-on plan could make Texas's tax trajectory far more predictable by the end of the decade.

For the half of this conversation who cares more about where you'll actually live: each of the four metros brings distinct advantages. San Antonio tends to rank among the more cost-efficient major Texas metros for overall tax bills. As we reported earlier this year, DFW led the country in new-home permits in early 2026. Austin's tech corridor keeps growing despite recent price softening. And Houston's flood zone changes are worth reviewing before you pick a ZIP code, because tax savings don't offset flood insurance costs if you land in a newly remapped high-risk area.

The bottom line: the homestead exemption is free to apply for, renews automatically each year, and is available to any Texas homeowner who uses the property as their primary residence. If you haven't yet filed, submit Form 50-114 with your county appraisal district. The annual deadline is April 30, but Texas accepts late homestead applications for up to two years after the delinquency date — so if you missed it, you can still file and capture the retroactive relief. After that, it takes care of itself.

Run your total monthly cost (mortgage + taxes + insurance) with current numbers before you sign anything. And if you're comparing Texas metros, the Houston vs Dallas affordability picture is worth a look before you commit to a county.
