A Arizona property tax appeal is how you challenge an over-stated home value and bring your bill back down. You do not appeal the bill itself — a Arizona property tax appeal challenges your home’s assessed value, and if that value is higher than what your home would sell for, lowering it lowers your tax. In Arizona, appeals are heard by County Assessor, then the County/State Board of Equalization or
Arizona Tax Court.
This guide covers who to file with, the deadline, how to build your case, and what happens at the hearing — all of it something you can do yourself, for free.

How a Arizona Property Tax Appeal Works
Your Arizona property tax is your assessed value multiplied by your local tax rate. You cannot vote down the rate, but you can challenge the assessed value — and that is where most overpayment hides. If the assessor has your home valued higher than a fair market sale price, you are paying more than your share, and a Arizona property tax appeal is the fix. For context on how often
values are set here: County assessors value property each year (for the following tax year); the Limited Property Value used for most taxes can rise no more than 5% per year (Proposition 117).
Owner-occupied homes are assessed at 10%. A Arizona property tax appeal is decided by County Assessor, then the County/State Board of Equalization or Arizona Tax Court, which reviews your evidence and can lower an over-stated value. It is an ordinary, expected step — assessors handle these every year, and you do not need a lawyer to start one.

The Arizona Property Tax Appeal Deadline
This is the part people miss. The window for a Arizona property tax appeal is short and firm. In Arizona: File a Petition for Review of Valuation (Form 82130) with the county assessor within 60 days of your Notice of Value (mailed by about March 1, for the following tax year). If denied, appeal to the Board of Equalization, then the Arizona Tax Court – or petition the Tax Court
directly by December 15.
Confirm your notice date. Mark the date the moment your assessment notice arrives — once the window closes, you generally wait until the next tax year to try again.
How to Prepare Your Arizona Property Tax Appeal
Your case is simply evidence that your home is worth less than its assessed value. The strongest proof is recent sales of similar homes near you that sold for less than your assessed value — three to five comparable sales make a solid packet. Also pull your property record card from the assessor and check it for plain errors: too much square footage, the wrong number of bedrooms or bathrooms,
a finished basement you do not have.
A factual error is one of the easiest wins, and it can carry a whole appeal on its own. A recent independent appraisal or photos of condition problems (a failing roof, foundation cracks) help too.

After You File Your Arizona Property Tax Appeal
After you file with County Assessor, then the County/State Board of Equalization or Arizona Tax Court, a Arizona property tax appeal usually gets a hearing where you present your evidence and the assessor presents theirs. Keep it factual and about value — comparable sales, not how much the bill hurts. Many appeals are settled or reduced at this stage. If you are not satisfied with the decision, most states allow
a further appeal to a state board or court; the notice you receive will explain that next step and its own deadline.
Whatever you do, keep paying the bill as billed while your appeal is pending, so you do not pick up penalties on top of everything else.
Don’t want to appeal your Arizona taxes yourself? A property tax appeal service can file everything for you and usually only charges if it wins — typically a share of what it saves you. It is one option; you can also appeal on your own for free.
