7 Pieces of Evidence That Win a Williamson County Tax Protest

Evidence decides a Williamson County tax protest, and volume does not. The appraisal district shows up with a value and a file behind it, so an owner who shows up with neither loses the room quietly. Seven kinds of evidence do most of the work, and each one can be gathered long before a hearing is scheduled.

7 things to know T. Kerr Property Group

Here is what each piece proves, what a strong version looks like, and the version that gets waved through.

The seven, in the order they get used:

01

Which comparable sales actually carry weight in a tax protest?

Closed sales are the backbone of a market value protest, because an appraisal is an opinion about what a property would sell for. A sale that already closed is not an opinion. The sales that carry weight match the subject on size, age, condition and location. Across the market buyers have been regaining leverage, so recent closings sometimes land below what the district assumed.

What good looks like

A good set is three to five closings, each with the address, the date, the size and the price. Pull them from inside the same subdivision where that is possible. In Georgetown, Round Rock and Liberty Hill, where T. Kerr Property Group works, a sale on the same street usually beats a better looking sale a mile away.

Red flag

A list of active listings is not evidence of value, because asking prices are hopes and hopes do not close. Anyone offering a screenshot of neighbors' asking prices is handing over an exhibit the panel can ignore.

02

Does what I paid for the house count as evidence?

A recent purchase price is direct evidence of market value for that exact property, and no adjustment is needed because the subject is the sale. The closing statement and the contract show the price, the date and the terms. This works best when the purchase was an arm's length deal between unrelated parties.

What good looks like

A good submission is the settlement statement itself, not a number typed into the protest form. Attach the contract, including any amendment that changed the price. Note anything unusual about the deal, such as a seller credit or repairs folded into the terms, because the appraiser will look for it anyway.

Red flag

A purchase that was not arm's length carries less weight. A sale between family members, an estate transfer or a foreclosure tells a panel very little about market value. Presenting one as a straight comparable invites a question that is hard to answer well.

03

Is it worth paying for an independent appraisal?

An independent appraisal is a written opinion of value from a licensed appraiser the owner hires. It carries weight because the method is documented and the appraiser is accountable for the work. It also costs money and takes time to schedule. The test is simple, since the fee has to be smaller than the tax it could save.

What good looks like

A good use is a property the district struggles to model, such as an acreage homesite, an unusual floor plan or a home with serious condition problems. Ask for an effective date that matches the valuation date the district used, because a report dated months later answers a different question.

Red flag

A market analysis printed off a website is not an appraisal, whatever the heading on it says, and panels know the difference. Paying for a report and then not reading it is the other failure, because an owner who cannot explain their own exhibit loses the room.

04

What kind of photographs actually help a protest?

Photographs work because the district values most homes from a desk, and nobody walked through the kitchen or looked at the slab. An image of a failing roof, a cracked foundation or an unfinished room supplies what the record does not have. Much of Central Texas sits on Blackland clay, and slab movement photographs well.

What good looks like

A good set is dated and labeled, with one line per image saying what it shows and where it was taken. Wide shot first, then the detail. A photograph of a crack means more with a tape measure or a level in the frame. Interior damage counts as much as anything visible from the curb.

Red flag

A folder of forty photographs with no captions buries the point, and panels have minutes rather than hours. Anyone submitting a gallery instead of a short labeled set is making the district's job easier and the owner's job harder.

05

Do contractor estimates for repairs count as evidence?

A written repair bid turns a visible problem into a figure the panel can subtract. Photographs show that a roof is failing, and a bid shows what curing it costs. The bid needs a letterhead, a date, a scope of work and a total on it. A verbal quote recalled from memory is not evidence.

What good looks like

A good bid comes from a contractor who would actually do the work, on that company's own paperwork, and two bids beat one. Central Texas heat is hard on roofs and cooling systems, so replacement quotes for both are common and easy to line up well before a protest is filed.

Red flag

A bid written to be helpful rather than accurate is a risk worth avoiding. Inflated numbers get tested, and a panel that doubts one exhibit starts doubting the rest. An honest bid that is smaller than hoped still beats a large one that falls apart.

06

Can an error in the district's own record win a protest by itself?

The appraisal district's record is evidence, and errors inside it are among the easiest wins available. The record lists living area, bed and bath counts, year built, lot size and condition. When it describes a house that does not exist, the value built on it is wrong. WCAD publishes the record for each account.

What good looks like

A good correction is specific and provable. Print the record, circle the wrong figure, and attach what proves the truth, whether that is a survey, a builder floor plan or a set of measurements taken with a tape. Fixing a square footage error helps in later years too, because the record carries forward.

Red flag

Reporting an error by phone and assuming it was handled is where these fall apart. Corrections belong in the protest file, in writing, with proof attached. A promise noted in somebody's call log is not something a panel can see.

07

How does the equity argument work when my market value looks fair?

The unequal appraisal argument compares a home against similar properties inside the same district. The claim is not that the value is wrong against the market. The claim is that it sits out of line with what comparable neighbors carry. This ground stands on its own, so a protest can win on equity alone.

What good looks like

A good equity case lists comparable properties by account, with size, age and appraised value side by side. Uniform subdivisions make this straightforward, because nearly identical plans sit next to each other. In parts of Georgetown such as Sun City, where builder plans repeat street after street, the comparison fits on one page.

Red flag

Picking the cheapest handful of accounts nearby and calling it equity does not hold up. The comparison has to be like for like. A panel that spots cherry picking discounts the whole exhibit, including the parts of it that were fair.

Common Questions

Frequently asked questions.

Can I use a Zillow or Redfin estimate as evidence in a tax protest?

Automated estimates are not accepted as proof of value, because nobody can explain how the model reached the number or what it knew about the property. Closed sales are the usable version of the same idea. Pull the sales the estimate was built from, confirm each one closed, and submit those instead.

How many comparable sales should I bring to the hearing?

Three to five well matched sales do more than a long list. Each one should be close in size, age, condition and location, with the address, date and price stated plainly. A panel reads the strongest exhibit and stops. Padding the file with weak sales gives the district something easy to attack.

What evidence does the appraisal district bring to a protest?

The district brings its own record for the property and the sales its model relied on. Ask what those sales were, and ask to see them, because the answer usually shows where the disagreement really sits. Sometimes the district used a sale that is not comparable at all, and that is worth pointing out.

What happens if I show up with no evidence at all?

The panel still hears the protest, but it decides on what is in front of it, which would be the district's file alone. Frustration about a bill is not evidence of value. The Texas Comptroller publishes the statewide rules for the protest process, and WCAD publishes the forms and the current deadline for a given year.

Will repairs I already finished hurt my protest?

Completed work can raise value, so the honest answer is that it might. Condition evidence is about what the district did not know on its valuation date. Photographs taken before a repair, along with the invoice, tell that story accurately. Hiding finished work is not an option worth taking.
