Every spring the appraisal district mails a notice of appraised value, and every spring a large share of the people who receive one are annoyed by it and do nothing. Protesting is free, the process is more mechanical than it sounds, and the evidence that moves the number is narrower than most people expect.
What you are actually arguing about
You are not protesting your tax bill and you are not protesting the rate. Rates are set separately by each taxing jurisdiction, and no appraisal district controls them. What you are protesting is the district's opinion of what your property was worth on January 1.
That distinction matters because it dictates what evidence is relevant. An argument that your bill went up more than you can afford is not an argument the process can hear. An argument that the district thinks your house is worth $600,000 when comparable houses nearby sold for $540,000 is exactly the argument it exists to hear.
There is a second ground, unequal appraisal, which argues that your property is assessed higher than comparable properties even if the district's market value is defensible. Both grounds can be raised together and usually should be.
The sequence
- The notice arrives. Typically in the spring. Read the deadline printed on it, because that date is the one that binds you.
- File the protest. Online through the Travis Central Appraisal District portal is simplest. File even if you are not sure you will pursue it. Filing preserves your right; missing the date ends it for the year.
- Request the district's evidence. You are entitled to see the data behind their number, including the comparables they used. This is the step most people skip and it is the most useful one, because their comparables are often where the weakness is.
- Informal review first. Most protests resolve here, in a conversation with a staff appraiser. Bring your evidence and be specific.
- Formal hearing if needed. If the informal review does not resolve it, you present to the Appraisal Review Board, a panel of citizens. It is less intimidating than it sounds and runs on a schedule.
Evidence that works, and evidence that does not
Mass appraisal is a model. It estimates value from sales data, square footage, age, and neighborhood, and it cannot see inside your house. Everything it cannot see is your opening.
What carries weight:
- Comparable sales close to January 1, genuinely similar in size, age, and location, that sold below your assessed value.
- Condition problems the model assumes away: a roof at the end of its life, foundation movement, an original kitchen, deferred maintenance. Photographs and contractor bids are the currency here.
- A recent purchase. If you bought the house near the assessment date for less than the assessed value, the closing statement is strong evidence of market value.
- An independent appraisal, if you have one for another purpose.
- Errors in the record. Wrong square footage, a bathroom you do not have, a pool that was filled in years ago. These are common and easily fixed.
What does not: that your bill rose sharply, that your neighbours are also unhappy, that you are on a fixed income, or that the increase seems unfair in the abstract. These are real grievances and the board has no authority over any of them.
The homestead cap does some of this for you
If you have filed for a homestead exemption, your assessed value for tax purposes is already limited in how fast it can climb year over year. In a rising market the capped value falls behind market value, and once that gap is wide enough, a protest arguing market value may not reduce your taxable value at all, because the cap is already binding.
So check the notice carefully. If your appraised market value and your capped taxable value are different numbers, work out which one is driving your bill before you spend time protesting the other. If you have not filed for the exemption at all, that is the larger win and it is covered separately in the homestead exemption.
Should you hire someone
Firms that handle protests generally charge a percentage of the savings they achieve. For a straightforward single-family home where the case is a handful of comparables, many owners do as well filing themselves, and the work is an evening. For an unusual property, a property with a genuinely complicated condition argument, or an owner with several properties, a firm that does this every day has more leverage and better data than you do.
Neither answer is wrong. What is wrong is doing nothing because the choice felt complicated.
The counties are not the same
The Austin metro spans several appraisal districts. Property in Round Rock, Cedar Park, or Georgetown is generally Williamson County, and Buda and Kyle generally Hays. Each district runs its own portal, its own calendar, and its own evidence procedures. Protest with the district that actually appraises your property.
What we do about it
If you bought through us we will pull the comparable sales for your protest, because that is the evidence the process runs on and we have direct access to it. We do not charge for that and we do not take a share of the outcome. Ask, and we will send the file.
