Do Property Tax Appeal Companies Take a Cut? (And How to Keep 100%)

Published September 21, 2026

If you've had a high assessment notice land in your mailbox, you've probably also had a postcard offering to fight it for you at no cost unless you win. So do property tax appeal companies take a cut? Almost always, yes — that "no cost unless you win" is a contingency fee, and the cut comes out of the savings before you ever see them.

The short version: there's nothing wrong with paying for help, but the headline percentage is the least important number in the contract. What decides your real cost is how many years of savings the fee covers and how the contract defines "savings." And nothing about a residential appeal requires you to hire anyone at all.

Model	You pay	Best when
Contingency	A share of the savings, only if they win	The case is large, complex, or commercial
Flat fee	A set price, win or lose	You want the analysis and the paperwork done
Do it yourself	Your own time, plus any filing fee	The case is a straightforward house with good comps

What a contingency cut actually costs

Start with the arithmetic, because it's less obvious than it looks. Say your appeal lowers your bill by $600 a year and the contract takes 40% of the savings. Your first-year share is $360 and the company's is $240. That's the version on the postcard.

Now apply the term that the postcard doesn't mention. If your area holds values between reassessments and the contract collects its percentage on every year the reduction stands, a three-year run looks like this:

	Year 1	Years 1–3
Savings won	$600	$1,800
Company's 40%	$240	$720
You keep	$360	$1,080

Illustrative figures — use your own bill and your own contract's rate.

Same percentage, triple the fee. That's not a gotcha so much as a term people don't think to look for, and it's the single biggest driver of what a contingency arrangement costs on a typical house.

The four terms that decide your real cost

1. How many years the fee covers. One year, or every year the lower value survives? This is the term above, and it's worth more than a ten-point difference in the rate.
2. How the contract defines "savings." Actual tax dollars you didn't pay is the honest base. A percentage of the value reduction is a different and much larger number, and a percentage of projected multi-year savings charges you today for years that haven't happened yet.
3. Whether there's a minimum fee. A flat minimum per parcel is reasonable on its face, but on a small win it can swallow most of your share — or, with some contracts, exceed it.
4. When the agreement ends. Many are written to continue until you cancel them. In Texas, this isn't just a contract question: Tax Code §1.111(c) provides that an appointment of agent stays in effect until it's revoked in writing filed with the appraisal district. An appointment signed with no expiration date doesn't lapse on its own — it keeps working, and keeps billing, until you file the revocation.

What Texas requires, and what it tells you

Texas is the most useful state to look at here, because it regulates this work by name. Under Occupations Code §1152.151, a person may not perform property tax consulting services for compensation without a certificate of registration from the Texas Department of Licensing and Regulation — and §1152.001 defines those services to include representing someone else in a protest before an appraisal review board. So the person who signs you up can be checked: TDLR publishes a public license search.

The exemptions in §1152.002 are worth knowing too, because "licensed" in an ad can mean several different things. Attorneys and CPAs are exempt, as are real estate brokers and licensed appraisers whose property tax work is limited to farms, ranches, and single-family homes. A credential on a business card isn't automatically a property tax consultant registration.

Two more things Texas puts in writing. The state's own agent-appointment form (Comptroller Form 50-162) carries a notice that §1.111(h) requires the comptroller to print in bold: "In some cases, you may want to contact your appraisal district or other local taxing units for free information and/or forms concerning your case before designating an agent." And §41.45(b) is explicit that an owner who files a protest is entitled to appear and offer evidence or argument. The state is telling you, on the form itself, that hiring an agent is optional and that the information is free.

Your state may do none of this. That's the point of checking: before you sign, spend ten minutes on your state's licensing agency and your county assessor's site to find out what protections actually exist where you live. Your state's property tax appeal guide is a reasonable place to start.

When paying a cut is the right call

Contingency pricing exists because it solves a real problem. It's a sensible deal when the stakes justify it:

• Commercial, industrial, or income-producing property, where the argument runs on income approaches and capitalization rates rather than a handful of house sales.
• An unusual property with few or no true comparables — acreage, a historic home, something custom.
• A case already headed past the local board, into a state tribunal or court, where procedure and deadlines get genuinely technical.
• You know you won't do it. A share of a win beats 100% of an appeal you never file. That's an honest reason, and it's the most common one.

How to keep 100% of the savings

For an ordinary house in a neighborhood with real sales, the work is small enough to do yourself:

1. Read your notice and find the value the county actually used, plus your filing deadline. The deadline is the part that can't be fixed later.
2. Check the gap. Convert the assessed value to the market value your county implied and compare it to what similar homes nearby actually sold for. Our guide to whether your home is over-assessed walks through it.
3. Price the win before you spend an afternoon on it — the reduction you can prove, times your tax rate, times the years it lasts. That's how much an appeal is worth.
4. Pull three or four closed sales that genuinely resemble your home, and adjust honestly against yourself where a comp is better than yours.
5. File the form and show up. Most boards hear homeowners without counsel every single day, and many jurisdictions charge nothing to file — check yours.

Before you sign anything

Ask for the fee in dollars, not percent, on a realistic win. Ask how many years it applies to. Ask what base the percentage is taken from. Ask what ends the agreement, and get that in writing. A firm that answers all four plainly is probably worth talking to. One that won't put the answers on paper has told you what you needed to know.

And run the comparison honestly: if a company's share of a three-year win is several hundred dollars, that's the number to weigh against an afternoon of your own time — or against a flat-fee tool that leaves the savings with you.

That last option is what PROppeal is: it pulls licensed comparable sales for your address, applies your state's assessment ratio and cap rules, tells you whether you have a case at all, and builds the letter to file. One price, paid once, and every dollar the appeal saves stays yours.

Property tax rules and deadlines vary by jurisdiction and can change — verify with your county before relying on this.
