Every year, millions of homeowners across Texas receive their property tax appraisal notices and face the same question: should I protest this myself, or should I hire a property tax protest company to handle it?
It's a fair question. Property tax protest companies charge fees — typically a percentage of whatever savings they achieve. Meanwhile, filing a protest yourself is technically free. So is it worth hiring a property tax protest company, or are you better off going the DIY route?
The answer depends on several factors: your property's value, the size of the assessment increase, your comfort with the process, and how you value your own time. In this guide, we'll break down the real costs, success rates, and trade-offs so you can make an informed decision.
Filing a property tax protest on your own is absolutely something you can do. Every Texas homeowner has the legal right to challenge their property's appraised value, and the process is designed to be accessible to non-professionals.
Let's run the numbers on a real-world example. Say your home is appraised at $400,000 and you believe the fair value is closer to $350,000. That $50,000 reduction would save you roughly $1,200 per year in property taxes (at a typical Texas tax rate of ~2.4%).
| Factor | DIY Protest | Professional Company |
|---|---|---|
| Filing cost | $0 | $0 (contingency) |
| Success rate | ~30% | 60–85% |
| Average reduction achieved | $400–$600/year | $800–$1,500/year |
| Fee | $0 | 20–50% of savings |
| Your time investment | 10–20 hours | 15 minutes to sign up |
| Net first-year savings (if successful) | $400–$600 | $400–$1,200 |
| Multi-year benefit | Same (if you re-protest each year) | Reduction often carries forward |
Here's the part most people miss: the value of your time. If you spend 15 hours researching, preparing evidence, and attending a hearing — and your hourly value is $50 — that's $750 worth of your time. If you achieve a $500 savings doing it yourself, you actually came out behind.
Meanwhile, a professional who charges 20% of a $1,200 savings takes $240, leaving you with $960 — and you didn't spend a single hour on it.
💡 The math is simple: If a protest company's fee is less than the value of your time plus the difference in expected savings, hiring a professional is the better financial decision.
This is where the difference between DIY and professional protests becomes most stark:
The gap in reduction amounts is equally significant. Professional firms often secure reductions 2–3x larger than what DIY filers achieve, because they have access to better data and more refined negotiation strategies.
"I spent three hours preparing my own protest last year and got a $200 reduction. This year I hired a company and they got me $1,400 off. I wish I'd done it sooner."
Not every situation calls for professional help, but there are clear scenarios where hiring a company is almost always worth it:
The higher your property's appraised value, the more potential savings are on the table. For homes valued at $300,000 or above, even a modest percentage reduction translates to hundreds or thousands of dollars in annual tax savings. At these values, the company's fee is easily offset by the savings.
If your appraised value increased by 10% or more in a single year, there's a strong case that BCAD or your local appraisal district overshot. Large increases are often the easiest to protest successfully — and professionals know exactly how to exploit the gap between the assessed value and market reality.
Commercial properties, multi-family homes, properties with structural issues, or homes in rapidly changing neighborhoods present complexities that require specialized knowledge. A professional firm has the expertise to handle exemption strategies, unequal appraisal arguments, and other advanced tactics.
Between researching comparable sales, pulling data, preparing an evidence packet, filing the protest, and attending one or two hearings during business hours, a DIY protest can consume 10–20 hours. If your time is worth more than the fee a company charges, outsourcing is the clear winner.
If you protested on your own last year and got a minimal reduction (or none at all), it's worth bringing in a professional. They'll know whether your case has merit and what evidence will actually move the appraisal panel.
Hiring a company isn't necessary in every case. Here's when you might be fine handling it yourself:
If your appraised value went up by less than 5% and your home is valued under $250,000, the potential savings may be modest enough that a DIY protest makes sense — especially if you're comfortable with the process.
A standard single-family home in a neighborhood with plenty of recent comparable sales is the easiest type of protest to handle on your own. The evidence is straightforward: here's what similar homes sold for, and your appraisal is higher.
If you've protested before, know how to pull comps, and don't mind attending a hearing, there's no reason you can't do it yourself. Some experienced homeowners protest successfully every year without professional help.
If BCAD has the wrong square footage, wrong number of bedrooms, or other factual errors on your property record, this is an easy fix that you can handle with a quick protest. Just bring documentation showing the correct information.
If you've decided to hire a professional, choosing the right company matters. Here's what separates the good ones from the rest:
The best protest companies work on a contingency basis — meaning they only charge if they actually reduce your taxes. If they don't save you money, you pay nothing. Avoid any company that charges upfront fees regardless of results.
Industry fees range from 20% to 50% of first-year tax savings. Lower is obviously better for you, but also consider what's included. A company charging 25% that handles everything including formal hearings is a better deal than one charging 20% but dropping your case after the informal stage.
Look for companies with documented success rates, customer reviews, and experience in your specific county. A firm that's been protesting in Bexar County or Harris County for years will have a significant advantage over a newcomer.
A good company will tell you upfront what they expect to achieve and explain their process clearly. Be wary of firms that promise specific dollar amounts or guarantee outcomes — no legitimate protest company can guarantee a result.
Make sure the company handles the entire process: filing the protest, preparing the evidence, attending the informal hearing, and — if necessary — representing you at the formal Appraisal Review Board (ARB) hearing. Some budget firms only handle the informal stage and drop your case if it doesn't settle there.
You should be able to check on your case status and get updates without chasing the company down. Look for firms with client portals, email updates, or responsive customer service.

Get Your Free Analysis →Most property tax protest companies charge between 20% and 50% of your first-year tax savings, on a contingency basis. This means you pay nothing if they don't reduce your taxes. OverAssessed charges just 20% — one of the lowest rates in the industry.
In most cases, yes. If you've already filed a protest but haven't had your hearing yet, you can authorize a professional to take over your case. It's best to do this early in the process so the company has time to prepare strong evidence.
Many do, yes. Commercial property tax protests are often more complex and involve larger dollar amounts, making professional representation even more valuable. Check with the specific company about their experience with commercial properties.
Not exactly, but it helps. Your appraised value can be reassessed each year. However, a successful protest establishes a lower baseline, and Texas law limits annual increases on homestead properties to 10%. This means a reduction this year creates compounding savings over time.
If you're working with a contingency-based company like OverAssessed, you pay nothing. That's the beauty of the contingency model — the company only earns a fee when they deliver real savings to you.
