Round Rock Property Tax Protest: How to Lower Your 2026 Tax Bill

If you just received your Notice of Appraised Value and your stomach dropped, you're not alone. Round Rock is one of the fastest-growing cities in Texas with a population exceeding 250,000, and rapid appreciation means WCAD appraisals are climbing aggressively. The median home value in Round Rock sits around $376,169 — and many homeowners are seeing assessed values that don't reflect reality.

The good news: you have the legal right to protest, and the numbers are in your favor. Williamson County homeowners saved $72 million from protests in 2024. This guide walks you through every step of protesting your Round Rock property taxes through WCAD (Williamson Central Appraisal District).

Is Your Round Rock Home Over-Assessed?

Your home is likely over-assessed if WCAD's appraised value is higher than what your home would actually sell for today. Round Rock's explosive growth — fueled by the Samsung semiconductor plant in nearby Taylor, Apple's continued expansion, and a wave of corporate relocations to the I-35 corridor — has driven assessed values up across the board. But mass appraisals don't inspect individual homes, which means WCAD may be valuing your property based on neighborhood-wide trends rather than its actual condition.

Common signs your Round Rock property is over-assessed:

  • Your appraised value jumped more than 10% from last year (even with a homestead cap)
  • Comparable homes in your neighborhood recently sold for less than your assessed value
  • Your home has deferred maintenance, outdated finishes, or functional issues WCAD doesn't know about
  • Nearby new construction inflated your neighborhood's average without reflecting your home's age
  • You're assessed higher than similar-sized homes on your street

How Much Can Round Rock Homeowners Save?

The savings are real and significant. In 2024, 54% of informal protests and 55% of formal ARB protests at WCAD resulted in value reductions. Across Williamson County, homeowners saved a combined $72 million.

What Does That Look Like for a Typical Round Rock Home?

With the median Round Rock home valued at ~$376,169 and combined tax rates often exceeding 2%, even a modest $25,000 reduction in appraised value saves you roughly $500+ per year — every year, compounding as values continue to rise.

A $50,000 reduction saves over $1,000 annually. Over five years, that's $5,000 back in your pocket — from a single protest that takes less than an hour to file.

How to File Your Round Rock Property Tax Protest (Step-by-Step)

Filing a protest is free and takes about 10 minutes online. Round Rock is in Williamson County, so your protest goes through WCAD (Williamson Central Appraisal District). Here's exactly how to do it:

1

Get Your Notice of Appraised Value

WCAD mails notices in early-to-mid April. Look for the “ONLINE PROTEST AVAILABLE” watermark and your Online Passcode — you'll need it to file electronically. If you haven't received your notice, search your property at search.wcad.org.

2

File Online at WCAD

Go to onlineappeals.wcad.org, enter your passcode, and select the reason for your protest. Most Round Rock homeowners choose “Value is over market value” and/or “Value is unequal compared with other properties.” Check both boxes — it gives you two angles of argument.

3

Gather Your Evidence

Strong evidence wins protests. Pull 3–5 comparable sales of similar homes in your Round Rock neighborhood that sold for less than your appraised value. Include photos of any condition issues — aging roof, foundation cracks, outdated kitchen. WCAD also provides their comparable sales when you file online; review theirs and counter with your own.

4

Attend Your Hearing

WCAD schedules hearings April through July. You'll first meet informally with a WCAD appraiser — this is where most protests are resolved. Present your evidence calmly and factually. If you can't agree, you proceed immediately to the formal ARB panel on the same day.

5

Accept or Escalate

If the informal or ARB hearing results in a satisfactory reduction, you're done — your new value takes effect for the 2026 tax year. If not, you can escalate to binding arbitration or district court, though most Round Rock homeowners resolve their protest at the informal stage.

Alternative Filing Methods

By Mail: Send Form 50-132 or the form on the back of your notice to 625 FM 1460, Georgetown, TX 78626-8050.
In Person: Deliver to WCAD's office at 625 FM 1460, Georgetown. Hours: Mon–Fri, 8am–5pm.

Round Rock Property Tax Rates Explained

Your Round Rock property tax bill isn't set by a single entity. Multiple taxing jurisdictions stack their rates, which is why the total can feel so high. Here's the breakdown:

City of Round Rock
~$0.36
Per $100 assessed value
Williamson County
~$0.37
County services, roads, public safety
Round Rock ISD
~$1.05
Largest share of your tax bill
Williamson County ESD
Varies
Emergency services, if applicable
Upper Brushy Creek WCID
Varies
Water district, certain areas only

The combined effective tax rate for most Round Rock homeowners falls between 1.8% and 2.1% of assessed value. That means on a home assessed at $376,169, you could owe $6,700 to $7,900 per year in property taxes. Reducing your appraised value directly reduces every line item on your bill — the school district portion alone accounts for roughly half.

Round Rock Neighborhoods Where Protests Save the Most

Not every neighborhood is assessed equally. WCAD's mass appraisal models can create significant disparities between similar homes, especially in large master-planned communities where lot size, upgrades, and condition vary widely. Here are the Round Rock neighborhoods where we see the most protest savings:

Forest Creek

Established golf course community with wide value ranges. Older sections often over-assessed relative to newer builds.

Teravista

Large master-planned community with 2,500+ homes. Mass appraisal struggles with the wide variety of builders and floor plans.

Paloma Lake

Newer development near Toll 45. Rapid appreciation means assessed values may outpace actual market conditions.

Brushy Creek

Mature subdivision with 1990s-era homes. Aging properties frequently assessed at values exceeding comparable sales.

Walsh Ranch

Premium homes near Walsh Middle School. Higher-value properties tend to have the largest absolute dollar reductions.

Sonoma

South Round Rock community near I-35. Proximity to commercial development can inflate residential appraisals.

Eagle Ridge

Hillside homes with view premiums unevenly applied. WCAD may not distinguish between view and non-view lots accurately.

Cat Hollow

Family-oriented community near parks and schools. Mix of renovated and original-condition homes creates protest opportunities.

Whether you're in one of these communities or elsewhere in Round Rock — Behrens Ranch, Highland Horizon, Siena, Round Rock Ranch, Old Settlers Park area, or downtown Round Rock — the same principle applies: if comparable homes are selling for less than your appraised value, you have a strong case to protest.

What to Expect at Your WCAD Hearing

WCAD uses a same-day hearing structure that's unique in Central Texas. Unlike Travis County (TCAD), where informal and formal hearings are scheduled weeks apart, WCAD handles both on a single visit. Here's what that looks like:

Step 1: Informal Meeting

You meet one-on-one with a WCAD appraiser. Present your comparable sales, photos, and any condition evidence. The appraiser can agree to a reduced value on the spot. This is where most Round Rock protests are resolved.

Step 2: Formal ARB Hearing (If Needed)

If you and the appraiser can't reach agreement, you proceed immediately to a three-member Appraisal Review Board panel. Present the same evidence — the board makes a binding determination. You are entitled to receive the Chief Appraiser's evidence at least 14 days before your hearing.

Virtual Option: RingCentral

Can't attend in person? WCAD offers virtual hearings through RingCentral. You enter a digital waiting room, meet informally via video, and proceed to a breakout room for the formal hearing if needed. Telephone hearings are available but only include the formal ARB stage.

Pro tip for Round Rock homeowners: experienced protesters recommend scheduling your hearing later in the season (June or July) when more recent comparable sales data is available to support your case. WCAD hearings run April through July, with the bulk of activity Monday through Thursday, 8am–5pm.

Round Rock Homestead Exemption: Are You Claiming Yours?

Before you protest, make sure you're claiming your homestead exemption — it's separate from the protest process and saves you money every year. If your Round Rock home is your primary residence, you qualify for:

  • $100,000 school district exemption (mandatory under Texas law)
  • Additional Williamson County and City of Round Rock exemptions
  • 10% annual appraisal cap on your homestead value (limits how fast your taxable value can rise)
  • Over-65 or disabled homeowner freeze on school district taxes

Apply through WCAD at wcad.org. If you purchased your Round Rock home in 2025 or 2026 and haven't filed, do this immediately — the homestead exemption combined with a successful protest can save you thousands. Learn more in our complete Texas property tax protest guide.

What is the property tax rate in Round Rock, Texas?
The City of Round Rock tax rate is approximately $0.36 per $100 of assessed value. Combined with Williamson County, Round Rock ISD, and special districts, the total effective rate typically ranges from 1.8% to 2.1%. On a $376,169 home, that's $6,700 to $7,900 per year.

The fastest method is online at onlineappeals.wcad.org using the passcode from your Notice of Appraised Value. You can also mail Form 50-132 to WCAD at 625 FM 1460, Georgetown, TX 78626, or deliver it in person.
How much can I save by protesting my Round Rock property taxes?
It varies by property, but Williamson County homeowners saved $72 million collectively in 2024. A typical $25,000–$50,000 reduction in appraised value saves $500–$1,000+ per year on your tax bill.
Does Round Rock have a homestead exemption?
Yes. The school district homestead exemption is $100,000, and Williamson County and the City of Round Rock offer additional exemptions. You must apply through WCAD. The homestead exemption also caps annual appraised value increases at 10%.
What evidence do I need for a Round Rock property tax protest?
The strongest evidence includes 3–5 comparable sales of similar homes in your area that sold for less than your appraised value, photos documenting any property condition issues, and data showing unequal appraisals of similar homes on your street. WCAD provides their comparable sales data when you file — review and counter it with your own.
Is Samsung's Taylor plant affecting Round Rock property values?
Yes. Samsung's $17 billion semiconductor facility in nearby Taylor has driven demand and values across the northern Williamson County corridor, including Round Rock. This growth can cause WCAD to over-appraise homes based on regional trends rather than individual property conditions.
