How to Protest Your WCAD Property Tax Assessment
Williamson County — home to Round Rock, Georgetown, Cedar Park, and Leander — has been one of the fastest-growing counties in Central Texas for over a decade. The Williamson Central Appraisal District (WCAD) appraises approximately 308,000 properties, and rapid population growth along the I-35 corridor means values have risen sharply. Filing a protest is free and is the most direct way to challenge an inflated assessment.
Can I Protest My WCAD Assessment?
Yes. Any property owner in Williamson County has the right to protest their appraised value. The process is designed for homeowners — no attorney or tax consultant required. WCAD resolves thousands of protests each year, and many homeowners receive reductions at the informal hearing stage.
When Is the Deadline?
The protest deadline is May 15 each year, or 30 days after your notice of appraised value is mailed — whichever is later. WCAD typically mails notices in mid-to-late April.
If May 15 falls on a weekend, the deadline extends to the next business day. Mail-in protests must be postmarked by the deadline date.

Step 1: Review Your WCAD Assessment
Start by looking up your property on Williamson Value to see your appraised value, comparable properties, and potential savings. Then verify the details on WCAD's website — check your square footage, year built, number of bedrooms and bathrooms, and property condition. Central Texas growth has led to mass appraisal adjustments that can overshoot, especially in neighborhoods with a mix of older and newer construction.
Step 2: Gather Your Evidence
The two most effective protest strategies in Williamson County:
- Unequal appraisal (equity): Show that similar properties in your neighborhood are appraised at lower values per square foot. Under Texas Property Tax Code Section 41.43(b), your appraised value should not exceed the median appraised value of comparable properties. The burden of proof falls on the appraisal district, not you.
- Market value: Show that recent sales of comparable homes indicate your property is worth less than WCAD's appraised value. Bring sale dates, addresses, and prices for homes similar to yours that sold in the last 6-12 months.
Williamson Value generates both types of evidence automatically using WCAD's own appraisal data and recent comparable sales.
Step 3: File Your Protest
WCAD provides an online protest filing system through their website, making it easy to file from home. To file online:
- Visit wcad.org and go to the "eFile Protest" section
- Enter your property account number and the access code from your Notice of Appraised Value
- Select the reason(s) for your protest — "Value is over market value" and/or "Value is unequal"
- Attach your evidence documents (comparable data, photos, estimates)
- Submit before the deadline
You can also file by mail using Texas Comptroller Form 50-132 sent to WCAD at 625 FM 1460, Georgetown, TX 78626. Call 512-930-3787 if you have questions about the process.
Step 4: Informal Hearing
After filing, WCAD schedules an informal hearing where you meet one-on-one with an appraiser. This is where the majority of Williamson County protests are settled. The appraiser reviews your evidence and may offer a reduced value. If the offer is acceptable, you sign an agreement and the protest is resolved.
Step 5: Accept or Proceed to ARB
If the informal offer doesn't meet your target, you move to a formal Appraisal Review Board (ARB) hearing. WCAD will notify you of your hearing date at least 15 days in advance.
Tips for Williamson County Protests
- Georgetown, Round Rock, and Cedar Park have seen dramatic value increases — always verify your comps are current
- Focus on 3-5 strong comparable properties with lower $/sqft assessments
- Check for data errors — wrong square footage, incorrect year built, missing condition notes
- You can protest every year with no penalty; even a small reduction adds up over time
- New construction neighborhoods often have wide valuation gaps — strong opportunities for equity arguments
- Call WCAD at 512-930-3787 with any questions about your notice or the protest process
Sources and evidence for Williamson County
Prepared by Williamson Value. Filing resources checked September 4, 2026.
Start with the Williamson Central Appraisal District property record and your current notice. Our property pages organize imported public assessment records and available comparable evidence. Check the tax year and data dates shown on each page: a prior-year record is useful history, but does not establish the value on a new notice.
Comparable homes are candidates for review. Verify their size, age, condition, location, and sale details before using them. Value per square foot helps screen candidates; it does not account for every difference. Estimated savings depend on the final assessment, exemptions, assessment limits, and applicable tax rates.
Texas filing and valuation checks
For 2026, the ordinary May 15 filing date has passed. A notice mailed later can have a later deadline. Confirm the date on your notice and the WCAD filing instructions. Review Texas Comptroller protest guidance for procedures and owner rights.
Separate a market-value argument from unequal appraisal, and compare the same tax year. A homestead cap or exemption can make taxable value differ from market value; lowering market value may not change the bill immediately. Texas sales coverage is incomplete because sale prices are not universally disclosed.
