The Central Texas Property Tax Playbook: How Travis, Williamson & Hays Compare in 2026

Why Your 2026 Appraisal Deserves a Second Look

If you own a home anywhere in the Austin metro, your property tax bill is the second-largest line item in your cost of ownership after the mortgage itself, and unlike the mortgage, it resets every single year based on a number a government office assigns to your house. That number is not handed down from on high. It's an estimate, produced at scale across hundreds of thousands of parcels, and estimates produced at scale contain errors.

This article is the data view. It's not a step-by-step "how to file" walkthrough so much as a way to think about Central Texas property taxes as a system: how the three core metro counties actually compare, where the hidden costs live, and how a homeowner, investor, or relocating buyer should reason about a protest. If you want the quick orientation before the detail, the chart below frames the whole landscape.

The headline most people miss is that Travis, Williamson, and Hays all land near a 2% combined effective rate, but "near 2%" hides a lot. The composition of that rate, and the value it's applied to, is where thousands of dollars a year are won or lost.

How TCAD, WCAD, and HaysCAD Set Your Value

Three separate appraisal districts cover the core metro: the Travis Central Appraisal District (TCAD), the Williamson Central Appraisal District (WCAD), and the Hays Central Appraisal District (HaysCAD). Each is responsible for assigning a market value to every property in its county as of January 1 each year. That January 1 valuation date matters: your 2026 notice reflects what the district believed your home was worth at the start of the year, not what it would sell for today.

Appraisal districts use mass appraisal. They model neighborhoods, apply per-square-foot values, and adjust for broad characteristics, but they do not walk through your house. They don't know your foundation has a crack, that your "updated" kitchen is original to 2004, or that the comparable two streets over sold for less because it backs to a retention pond. Mass appraisal is accurate in aggregate and frequently wrong on the individual parcel. That gap is the entire basis for a protest.

The other thing to understand is that the district's value and your *tax bill* are two different things. The district sets value; dozens of separate taxing units, the county, the city, the school district, the community college, the hospital district, and any special districts, each set their own rate and apply it to that value. Add them together and you get the combined effective rate.

Travis vs. Williamson vs. Hays: The Comparison That Actually Matters

Here's where a multi-county view earns its keep. Two buyers comparing a $500,000 home in Travis against a $500,000 home in a newer Williamson master-planned community often assume the tax cost is the same. It usually isn't.

The driver of the spread is special districts, and specifically MUDs, Municipal Utility Districts. When a developer builds a master-planned community on the metro's edge, a MUD is frequently created to finance the water, sewer, drainage, and road infrastructure. That debt is repaid through an additional tax levied on the homes inside the district, often in the range of 0.3% to 1.0% on top of the base rates, declining over time as the bonds are paid down.

This is why Williamson and Hays, where so much of the recent growth is new master-planned construction, can carry a higher all-in rate than mature, MUD-light parts of Travis. The Austin urban core was built out before this financing model became standard, so a 1950s home in central Austin and a 2023 home in a Williamson MUD can sit a full percentage point apart on effective rate even at the same price.

For a buyer, the practical move is simple: never compare two homes on price alone. Pull the actual tax history and the specific taxing jurisdictions for each parcel. A home that looks $40,000 cheaper can cost more to own once a MUD levy is in the picture. For investors running cash-flow models, the difference between a 1.9% and a 2.4% all-in rate on a $400,000 rental is roughly $2,000 a year, straight off the bottom line, every year you hold it.

The Calendar You Can't Miss

Texas property tax runs on a fixed annual cycle, and the single most important fact for *this* article, written in late June 2026, is that the 2026 protest window has already closed. The standard deadline is May 15, or 30 days after your appraisal notice is delivered, whichever is later. For most Central Texas owners, that date has passed for this year.

So the calendar splits into two tracks:

• **Right now (summer 2026): ARB hearing season.** If you filed a timely protest this spring, you're in the appraisal review board (ARB) phase. Informal reviews and formal ARB hearings run through the summer. If that's you, your job is to show up prepared, not to assume the number is final.
• **Planning for 2027.** If you missed the 2026 window, the most valuable thing you can do is set yourself up to protest early next year. Watch for your notice in the spring, calendar your specific deadline the day it arrives, and start gathering evidence before you need it.

Because dates and procedures vary by county and change year to year, confirm your exact deadline and hearing schedule directly with TCAD, WCAD, or HaysCAD. Do not rely on last year's date or a neighbor's recollection. The appraisal district websites publish the current calendar, and missing the deadline by a day forfeits the entire year.

Building Your Protest: Comps, Condition, and the Equity Argument

A protest is an evidence exercise, and there are three distinct arguments you can make, often in combination.

The market-value argument. You're claiming the district's value exceeds what the home would actually sell for. The evidence is comparable sales: recent transactions of similar homes near yours, adjusted for size, age, and condition, ideally sales near the January 1 valuation date. The strongest comps are close in proximity, time, and characteristics. One distant or stale comp undercuts your credibility; three tight ones build it.

The condition argument. Mass appraisal assumes an average-condition home. If yours has deferred maintenance, an aging roof, foundation movement, an unrenovated interior, photos and contractor estimates can justify a lower value. This is the part of your house the district has never seen, and it's frequently the most persuasive evidence you bring.

The equity (uniformity) argument. Texas law entitles you to be appraised uniformly with comparable properties, not just at or below market. If similar homes in your neighborhood are assessed lower than yours, that unequal appraisal is itself grounds for a reduction, sometimes even when the market-value case is weak. Appraisal districts publish the data needed to build this argument, and it's the one most DIY protesters overlook.

The through-line: bring specific, local, recent evidence. A protest that says "my taxes are too high" loses. A protest that says "here are three comparable sales and two equity comps that put my value at $X" wins more often than not.

The Homestead Exemption and the 10% Cap

If the property is your primary residence, the homestead exemption is the most important paperwork you'll ever file with your appraisal district, and it's separate from any protest. It does two things.

First, it removes a portion of your home's value from school-district (and often other) taxation, lowering the base your rate is applied to. Second, and this is the part that compounds, it caps how fast your *taxable* value can rise: no more than 10% per year, regardless of how much the market value jumps.

The cap math is where homestead protection really shows up. Say the district carries your market value at $500,000 and, after a hot year, raises it to $600,000, a 20% jump. Without the cap, you'd be taxed on the full $600,000. With the homestead cap, your taxable (assessed) value can rise only to $550,000 this year, with the remaining increase "deferred" into future years if the market value stays high. In a fast-appreciating metro like Austin, that cap can save a long-tenured owner thousands of dollars annually, and it's a key reason a homesteaded primary residence and a non-homesteaded rental next door can have very different tax bills on identical houses.

Two things to watch. The cap resets when a property sells, so a relocating buyer should expect their first-year taxable value to reflect the full purchase-driven market value, not the prior owner's capped number. And the exemption only applies if you've actually filed for it, new owners and recent movers should confirm their homestead is on file with the correct appraisal district.

Informal Review vs. the ARB Hearing

Most protests resolve before they ever reach a formal hearing. The process generally has two stages.

The informal review is a conversation, often online or with a single appraiser, where you present your evidence and the district may offer a reduction on the spot. A large share of protests settle here, and for many homeowners with a clean comp-based case, the informal offer is reasonable enough to accept. It's low-friction and worth taking seriously.

If the informal offer doesn't reflect your evidence, you proceed to the ARB hearing, a formal proceeding before the independent appraisal review board, a panel of citizens, not appraisal district employees. You present your case, the district presents theirs, and the board rules. It's more formal but not adversarial in the courtroom sense; bring organized evidence, state your requested value, and let the comps do the talking. If you're in hearing season right now on a 2026 protest, this is the stage you're navigating.

Beyond the ARB, there are further appeal routes (binding arbitration or district court) that can make sense on higher-value or commercial properties, but for a typical homestead, the informal-then-ARB path is where the decision gets made.

DIY vs. Hiring a Firm

You have three realistic options, and the right one depends on your time, the dollars at stake, and your appetite for the process.

Do it yourself. Entirely viable for a single homestead. The appraisal districts have made evidence accessible, and a homeowner who pulls a handful of solid comps and documents condition issues can absolutely win a reduction. The cost is your time, a few hours, mostly, and the upside is you keep 100% of the savings.

Hire a protest firm. These companies file and argue on your behalf, typically for a contingency fee, often around a quarter to a half of the first-year tax savings, with no upfront cost on most residential agreements. For owners who don't want to spend the time, or who own multiple properties, the convenience is real and the fee only applies if they win. The trade-off is that you split the savings and the firm's incentives are volume-driven, so a marginal case may not get the same attention a standout one does.

Hire it out selectively. Many investors DIY the simple parcels and hand the complex or high-value ones to a firm. That's often the most economical split.

For relocating buyers and investors specifically, my advice is to treat the protest decision as part of underwriting, not an afterthought. Model the property's tax cost at its post-sale (uncapped) value, confirm the jurisdictions and any MUD, and decide upfront whether you'll protest annually. Building that into the plan is how you keep a Williamson MUD or a hot Hays appraisal from quietly eroding your returns.

The Bottom Line

Central Texas property taxes cluster near 2%, but the cluster is deceptive. The composition of that rate, especially MUD levies in the newer Williamson and Hays communities, plus the homestead cap math and the strength of your protest evidence, can swing your annual carrying cost by thousands of dollars on the same nominal price. Travis, Williamson, and Hays are not interchangeable, and treating them as such is how buyers overpay to own.

For 2026, the protest window has closed and the work now is twofold: if you filed, show up to your ARB hearing with organized comps and condition evidence; if you didn't, set a reminder to protest early in 2027 and confirm your exact deadline with your appraisal district, since these dates move. Either way, make sure your homestead exemption is on file, because the 10% cap is the most valuable long-term protection you have.

If you're buying into the metro and want the real tax picture on the homes you're weighing, including which carry a MUD and what your first-year uncapped bill is likely to look like, that's exactly the kind of underwriting I do before clients write an offer. You can read more about my [buyer process](/buying) or [get in touch](/contact) with the addresses you're considering and I'll pull the tax history and jurisdictions for each. For the new-construction angle, where MUDs are most common, [the summer new-construction guide](/insights/new-construction-homes-central-texas-summer-2026) and [the Georgetown growth piece](/insights/georgetown-fastest-growing-suburb-2026) are good companions to this one.
