May 15. That is the date that decides whether you get a shot at lowering your Texas property tax bill this year or spend the next twelve months paying a number you never agreed with. I have watched neighbors miss it by a single day, shrug, and write the same oversized check for another cycle because they figured the window would reopen. It does not.
Here is the good news: the process itself is not complicated once you understand the order of operations. File on time, gather the right three pieces of evidence, and show up ready to talk about numbers instead of feelings. This piece walks you through the deadline rules, the evidence that actually moves an appraisal review board, and the specific mistakes that quietly kill otherwise solid protests.
Why the Deadline Is the Whole Ballgame
Texas gives you a firm window to challenge your appraisal, and it closes fast. In most counties the deadline lands on May 15, though it shifts if the appraisal district delivers your notice late in the season. When that happens, you generally get a set number of days from the notice date rather than a fixed calendar day.
That detail trips people up every spring. They wait for a notice that either arrived weeks ago in a plain envelope or never showed up at all, and by the time they think to check, the window is gone. You do not need a notice in hand to protest. You need to know your county’s rules and your property’s status. The State of Texas maintains the official portals and county directories, so that is where I would start if you are unsure which appraisal district covers your address.
Miss the deadline and your options shrink to almost nothing. There is a narrow late-protest path for specific situations, like a clerical error or a homestead exemption you qualified for but never received. Those are exceptions, not a backup plan. Treat May 15 like a hard wall, because in practice it is.
What You File, and What It Costs You
Filing a protest in Texas is cheap. The notice of protest form runs a couple of pages, and the filing fee is usually nothing at all. You can submit it online through most county portals, by mail, or in person. I would use the online route every time, mostly because you get a timestamp and a confirmation number without standing in a hallway.
The form asks why you disagree. You get a list of boxes: value is excessive, value is unequal, exemption was denied, and a few others. Most homeowners should check the first two. Excessive means the district’s number is higher than what your property is actually worth. Unequal means similar properties in your neighborhood were valued lower than yours.
That second box is the one people skip, and it is often the stronger argument. If every house on your street has a taxable value in the low three hundreds and yours sits at four hundred, you have a real case regardless of what the market did last year.
Three Kinds of Evidence That Actually Work
I have sat through enough of these hearings to know that the board does not care how you feel about taxes. They care about documents. Bring paperwork and you get a conversation. Bring frustration and you get a polite dismissal.
Recent comparable sales. Pull three to five homes that sold in your neighborhood within the last year, and keep them as close to your square footage and age as you can. The district uses this same data to justify its number, so you are speaking its language when you bring your own set.
Photos and repair estimates. A cracked foundation, a roof at the end of its life, a kitchen that has not been touched since the nineties. Get a contractor to write an estimate on letterhead. A number on paper beats a description every time.
The unequal appraisal list. Ask the district, or use its public portal, to pull comparable properties and their assessed values. If you find five homes similar to yours assessed lower, print the list and bring it. This is the evidence that wins quietly, without drama, because the math does the arguing for you.
The Texas Comptroller of Public Accounts publishes the property tax basics and the statewide rules that govern appraisal districts. Read the sections on protest procedures before you file. An hour with those pages will save you from a lot of guesswork, and it will keep you from walking into a hearing without knowing what the board can and cannot do.
The Week 22 Sandwich
Here is a scheduling problem nobody warns you about. Texas requires most appraisal districts to send notices somewhere around April, which leaves you roughly three to four weeks to build a case if you want to file comfortably before the deadline. That sounds manageable until you stack it against actual life.
I call it the Week 22 Sandwich because it lands right in the middle of the school year’s final stretch, spring sports, and the first real heat of the year. Your notice shows up, you set it on the counter, and then a kid has a tournament, work gets busy, and suddenly it is May 12.
My fix is boring but it works. The day your notice arrives, do three things in one sitting: photograph the notice, pull your county’s deadlines, and calendar a two-hour block for the following weekend. Two hours is enough to gather comps and fill out the form. What kills protests is not complexity, it is delay.
The Appeal Route and the Professionals Who Run It
If the review board sides with the district, you can escalate. Homeowners and commercial owners both have a path to binding arbitration or to district court, depending on the value and the type of property. That process is slower, more formal, and much less forgiving of paperwork errors.
This is where a lot of people hand the whole thing off. Texas allows licensed agents and attorneys to represent you at the appraisal district, which is why property tax dispute companies exist in the first place. The good ones handle the filing, pull the comp data, and argue your case while you go to work. The catch is that you still have to sign the agreements and you still have to decide which route fits your situation. Nobody can make that call for you.
A Quick Decision Framework
Not everyone needs help, and not everyone should go it alone. Run your situation through this before you spend a dollar or an afternoon.
- Go solo if your property is a standard homestead, your evidence is a handful of neighborhood sales, and you are comfortable speaking for five minutes about numbers.
- Get help if you own commercial property, multiple parcels, or anything with a complicated income approach behind its valuation.
- Get help if you have missed the deadline before, or if you simply know you will not follow through when the calendar gets tight.
- Just file something if you are on the fence. A flawed protest beats no protest. You keep your right to escalate, and districts frequently settle before a hearing anyway.
One more thing worth knowing: the Texas Attorney General publishes consumer protection guidance that covers how service providers in this space are supposed to operate. If a company promises guaranteed savings or asks for money upfront before doing any work, that is your cue to walk away.
Do the math on your own bill once. Take your assessed value, subtract what you think the property is honestly worth, and multiply the difference by your local rate. On a two hundred thousand dollar gap in a district with a two percent rate, you are looking at roughly four thousand dollars a year, and that gap compounds every year you leave it alone.
So set a reminder for early April right now. Not May. April. Pull your notice the day it lands, block the two hours, and file before the panic sets in. Then tell me: what is the one piece of evidence you have been sitting on that could shrink your bill this year?
