What form do I need?

There is no single national appeal form — each state (and sometimes each county) has its own. Always download the current version from the official state tax authority or county appraisal/assessor office, because forms are revised and stale third-party copies are rejected.

The major-state forms:

• Texas — Form 50-132, Property Owner's Notice of Protest, filed with the Appraisal Review Board. (Texas does not require you to use the form to request a hearing, but it is the standard route.)
• New Jersey — Form A-1, Petition of Appeal, filed with the County Board of Taxation by April 1; see the NJ Division of Taxation appeal page.
• Florida — Form DR-486, Petition to the Value Adjustment Board, filed with the county Clerk within 25 days of the TRIM notice.
• California — Form BOE-305-AH, Assessment Appeal Application, filed with the county Clerk of the Board (see the CA BOE assessment-appeals FAQ).
• New York — Form RP-524, Complaint on Real Property Assessment, filed with the local Board of Assessment Review.
• Ohio — Form DTE 1, Complaint Against the Valuation of Real Property, filed with the county Board of Revision by March 31.

How to find yours if your state isn't listed: search "[your state] department of revenue property tax appeal form" or go directly to your county assessor/appraisal-district website's appeals or forms page. The official form will be hosted on a .gov (or a state-chartered appraisal-district) domain.

Before you file, check: that you have the current tax-year version, that you've entered the correct parcel/account number, and that you've attached any required evidence schedule (NJ's comparable-sales schedule, for example, attaches at filing).

Bottom line: the form follows your state's statutory vocabulary — protest, petition, grievance, complaint, or appeal — so match the form to the term your state uses and pull it from the official source.
