The envelope looks official. It has your name, your parcel number, sometimes your assessed value, and a headline like “IMPORTANT: Property Tax Review” or “Homeowner Tax Reduction Notice.” It sets a deadline and asks for a fee — often a few tens of dollars, sometimes more — to “review” or “reduce” your property taxes. Here is the part the sender is counting on you not to know: nearly everything that letter offers to do for a fee, your county does for free, and in the two largest states where these mailers circulate, the letter is legally required to tell you it is not from the government.
These letters land in the greatest numbers right before exemption and appeal deadlines, and they lean hardest on older homeowners — which is why attorneys general in Texas, California, and Washington, along with the Los Angeles County tax collector and the Pennsylvania Department of Revenue, have all issued public alerts about them. This is a field guide to the envelope: the three things it might be, the thirty-second test that separates them, and the free version of whatever it is selling.
Before you do anything, decide which of these three you are holding. The design on the page won’t tell you; the sender and the ask will.
Sent by your county assessor, appraisal district, or tax collector. It announces a new assessed value, a reassessment, or an exemption you may qualify for. There is no fee to respond, and this is the one whose deadline genuinely matters.
Keep it · note the deadline
A private company offering, for a fee, to file your exemption or handle your appeal. This is not a scam and the company may be perfectly legitimate — but you are paying for a service you can often do yourself for nothing.
Optional — compare against the free path
Takes your fee and your personal information and files nothing, or “files” a form that was always free. It is defined by unlawful behavior: the required disclaimer is missing, money is taken without the service being rendered, or the point is to harvest your data.
Report it · don’t pay
Why the distinction matters: aggressive marketing, a high fee, and an official-looking layout do not by themselves make a letter a scam — they describe an ordinary category-2 solicitation. What moves a letter into category 3 is illegal conduct: no legally required disclaimer, or taking your money without doing the thing. Most of what arrives in the mail is category 2, which is exactly why the fine print is worth reading.
You don’t need to be a tax expert. Two things — who sent it and what they want — sort almost every letter correctly.
.gov website or a county officeThe fine print is the tell. A private mailer that is playing by the rules will disclose, somewhere on the page, that it is not the government. That sentence is not boilerplate you can ignore — it is the single most useful line on the letter. Find it before you do anything else.
Two of the largest states have already legislated the exact sentence a for-fee solicitation must print. Knowing it turns a confusing envelope into an easy call.
What the statutes actually require
California — Business and Professions Code § 17533.6. Any solicitation that uses a name, seal, or format resembling a government agency must display, on the front and back of every page and in at least 12-point boldface capital letters: “THIS PRODUCT OR SERVICE HAS NOT BEEN APPROVED OR ENDORSED BY ANY GOVERNMENTAL AGENCY, AND THIS OFFER IS NOT BEING MADE BY AN AGENCY OF THE GOVERNMENT.”
Texas — Property Code § 41.0051. A written advertisement offering, for a fee, to designate your property as a homestead must carry, in 14-point boldface: “THIS DOCUMENT IS AN ADVERTISEMENT OF SERVICES. IT IS NOT AN OFFICIAL DOCUMENT OF THE STATE OF TEXAS.” A company that solicits by mail or phone to pursue a tax refund for you must also name the taxing body that owes the refund before taking your money. Skipping the disclaimer is a deceptive act under the Texas Deceptive Trade Practices Act (§ 17.46), enforceable by the attorney general.
The disclaimer is the sender telling on itself. When a letter carries that line, it is a private solicitation, full stop — and when a fee-charging letter lacks it in a state that requires it, that omission is itself a violation you can report.
Not every state has a statute this specific, but the pattern is national. Consumer-protection offices in California and Texas, the Los Angeles County Treasurer and Tax Collector, the Washington attorney general, and the Pennsylvania Department of Revenue have each warned that no government office requires an outside company to process standard property-tax relief — and that the mailings tend to spike right before deadlines and to target seniors, who are likeliest to read an official-looking notice as a bill that must be paid.
These letters hide two very different jobs under one vague word. Split them apart, because one is trivial and one is real work.
This is a simple administrative filing. The company fills in a one-page county form and mails it for you. Doing it yourself is free, and many counties now accept the form online in a few minutes. The steps are the same everywhere:
.gov).Our deep dive on senior and disability exemptions walks through the major state programs, and the piece on exemptions vs. appeals explains which lever fits your situation.
The bottom line on exemptions: no legitimate government office requires you to pay an outside company to claim a standard exemption. If a letter charges you to “file” one, you are paying for postage.
This one is not a form you drop in the mail, and it is worth being honest about that. An appeal means demonstrating that your assessment is higher than your home’s market value — usually with three to five comparable sales — through an adversarial process that carries no guaranteed outcome. It takes time and evidence. A homeowner can absolutely do it: most of the work is gathering the right comparable sales and meeting the deadline. But “a company can handle it” is not the same as “you’re not allowed to.”
If you want to run the numbers yourself, our guide to finding comparable sales evidence is the core skill, and the DIY-vs-hire decision matrix lays out when each path makes sense. If you’d rather see the math before deciding, the service-vs-DIY breakeven calculator compares what a contingency fee costs against your time.
Not wanting to file your own appeal is completely reasonable. The fix is to choose a company you vetted, instead of the one that showed up uninvited.
Plenty of homeowners don’t want to assemble comparable sales or sit through a hearing, and hiring help is a perfectly sound decision. The difference between a mystery mailer and a real option is that you picked the second one with your eyes open. Before you sign anything, understand the fee model (a flat fee versus a contingency cut of your savings), read the auto-renewal terms, and confirm exactly what the fee buys.
Our honest comparison of property-tax service companies lays out how the major firms price their work, and the breakdown of how contingency-fee “savings” are actually calculated shows what to check in any contract before you sign. The point was never “never pay anyone.” It is: never pay the envelope that arrived unsolicited without knowing it’s a private company and what the free path would have cost you.
Not necessarily. Most of these letters are legal solicitations from private companies — you are paying a fee for something you can usually do yourself for free, such as filing an exemption or an appeal. A minority are outright scams that take your money and file nothing. The way to tell is the return address, the fee request, and the fine print — not the official-looking design, which is easy to fake.
A genuine notice comes from your county assessor, appraisal district, or tax collector; it references your parcel or account number in an official format; and it never asks you to pay a private company by credit card. If you are unsure, do not call the number or visit the website printed on the letter — look up your county assessor’s office independently and contact them directly to confirm.
No. Standard exemptions — homestead, senior, disability, and veteran — are filed free with your county, and many counties accept the form online in a few minutes. No government office requires you to use an outside processor, and paying one buys you little more than a stamp and an envelope.
The deadline printed on a solicitation is usually a sales tactic designed to create urgency. The deadlines that actually matter are your county’s exemption and appeal filing dates, which you can confirm on the county’s official website — not on the letter you received in the mail.
