THIS ASSESSMENT REDUCTION FILING SERVICE IS NOT ASSOCIATED WITH ANY GOVERNMENT AGENCY. IF YOU DISAGREE WITH THE ASSESSED VALUE OF YOUR PROPERTY, YOU HAVE THE RIGHT TO AN INFORMAL ASSESSMENT REVIEW, AT NO COST, BY CONTACTING THE ASSESSOR'S OFFICE DIRECTLY. IF YOU AND THE ASSESSOR CANNOT AGREE TO THE VALUE OF THE PROPERTY OR IF YOU DO NOT WISH TO CONTACT THE ASSESSOR YOU CAN OBTAIN AND FILE AN APPLICATION FOR CHANGED ASSESSMENT WITH THE COUNTY BOARD OF EQUALIZATION OR ASSESSMENT APPEALS BOARD ON YOUR OWN BEHALF. AN APPEALS BOARD HAS THE AUTHORITY TO RAISE PROPERTY VALUES (BUT IN NO CASE HIGHER THAN THE PROPOSITION 13 PROTECTED VALUE) AS WELL AS TO LOWER PROPERTY VALUES.

Required disclosures

California has a statute written for this exact business: Business and Professions Code §17537.9, which governs an “assessment reduction filing service.” This page lays out every constraint it puts on us, and what we do about each one. Every quotation is the text as enacted, from leginfo.legislature.ca.gov.

1. §17537.9(b) — the disclosure we must show you

The heavy-ruled box at the top of this page, and at the top of the page where you sign, is required by law, word for word. The statute addresses advertising and promotional material, so we place the full-size box where an offer is actually made — the signing step — and here, where the disclosure itself is the subject. Every other page carries the same disclosure as a plain-language summary in its footer, with a link back to this page. The size of the full box is set by law too:

The disclosures specified in paragraph (1) shall be placed at the top of each page of every advertisement or promotional material disseminated by an offeror of an assessment reduction filing service and shall be printed in not less than 12-point boldface font type that is at least 2-point boldface font type sizes larger than the next largest print on the page and enclosed in a box formed by a heavy line. BPC §17537.9(b)(2)

The statute's words “at least 2-point boldface font type sizes larger than the next largest print on the page” mean the disclosure has to be the biggest type on any page that carries it. That is why this page and the signing step have no oversized headline or giant hero line. It is not a style choice; it is what the statute produces. We turned it into a check that runs every time: our compliance self-check renders those pages and fails on any type size over the ceiling.

2. §17537.9(c) — when we are allowed to take money

No offeror of an assessment reduction filing service shall charge, demand, or collect any money in connection with a request for review until after the request is filed with the assessor. No offeror of an assessment reduction filing service shall charge, demand, or collect any money in connection with an assessment appeal application until after the application is filed with the clerk of the assessment appeals board. BPC §17537.9(c)

What we do about it

3. §17537.9(e) — written authorization

It is unlawful for an offeror of an assessment reduction filing service to file a request or application of any kind for reduction in assessment without first obtaining a written authorization from the property owner. A true and correct copy of the written authorization shall be submitted with any request or application for reduction in assessment. The offeror shall maintain the original written authorization for a period of three years and shall make it available for inspection and copying within 24 hours of a request without a warrant to law enforcement, the Attorney General, district attorney, or city attorney. BPC §17537.9(e)

What we do about it

4. §17537.9(a) — claims we may not make

Subdivision What it prohibits What we do
(a)(1) Representing that filing an application will guarantee a lower property tax We never say that. What we commit to is “no tax savings, no fee” — a contingent fee, not a promised outcome.
(a)(3) Claiming you will be represented in person at a hearing, unless the fee covers it At this stage we do not claim to attend. We have no registration number yet, so you appear in person.
(a)(4) Claiming the forms will be completed for you except for the signature, unless the fee covers it It does. We fill the forms out to the point where only your signature is missing.
(a)(6) Claiming to be a government agency or affiliated with one; misusing a government seal; a company name that contains both “appeal/tax” and “agency/assessor/board/…/county/city” No seals, no government color palette, nothing that reads as “an official partner.” Our company name is checked automatically.
(a)(6)(D) Envelopes we mail must carry “THIS IS NOT A GOVERNMENT DOCUMENT.” in capitals on the front Everything we mail carries it.
(a)(7) Pressuring you with “respond by this date or a late charge applies” We invent no deadlines and charge no late fees. The only real deadline is the county's: November 30.

5. What you can already do for free

  • You can contact the Office of the Assessor directly and ask for an informal review at no cost.
  • You can file an Application for Changed Assessment with the Assessment Appeals Board yourself (the county charges $46).
  • You are under no obligation to use this service, or any service like it.

The California Attorney General keeps a standing consumer alert about this industry. We link to it on purpose: oag.ca.gov/consumers/general/prop_tax_scam. The tactics it names are official-sounding company names, mail dressed up as a government document, invented “Regional Processing Center” addresses, and threats of a late charge. We do none of them — and we would rather you hold that checklist up against every company that contacts you, including us.

6. California has no statewide property tax agent license

AB 2415 (2014) would have created a statewide registration requirement for property tax agents. The Governor vetoed it on September 29, 2014. So when a company claims to hold a “California property tax agent license,” that license does not exist. Los Angeles County Code 2.165 Tax Agent registration is the county's only bar, and it covers decline-in-value work with the Assessor, not just the appeals board.

7. This site is not legal or tax advice

We are not a law firm and not an accounting firm. What's on this site is our own reading of public statutes and official forms. It is not legal advice and it is not tax planning. If a trust, an estate, a title structure, or multi-year tax planning is involved, talk to your own attorney or CPA.
