What is a property tax appeal?
A property tax appeal is a formal challenge to the assessed value of your property as determined by your local tax assessor. If your property is overassessed, you may be paying more in property taxes than you legally owe.
How to appeal your property tax assessment
Property tax appeal deadlines are strict and vary by state — typically between 30 and 90 days from when you receive your assessment notice. In many states, the deadline is May 15 or within 30 days of the assessment notice. Missing this deadline usually means waiting until next year.

Property / Tax Appeals in Arizona
Disputing property valuations or tax assessments in Arizona can significantly impact your financial well-being. Whether you believe your property has been overvalued, or you are challenging a specific tax assessment, understanding the appeal process is crucial. Arizona law provides clear avenues for property owners to challenge these decisions, ensuring fairness and accuracy in taxation. This guide will help you navigate the complexities of property and tax appeals in Arizona.
Property and tax appeals in Arizona are primarily governed by Arizona Revised Statutes (A.R.S.) Title 42, Taxation, specifically Chapter 16, which details property tax appeals and reviews. For instance, A.R.S. § 42-16001 outlines the designation of a taxpayer agent. Recent legislative actions, such as House Bill 4121 (2026), modify the property tax appeal process by requiring taxpayers to send copies of their appeal petitions to the county assessor. Additionally, the city residential rental sales tax was repealed effective January 1, 2025, impacting certain property owners. These laws and advisories are crucial for protecting Arizona consumers.
The Arizona Department of Revenue (ADOR) is a key state agency involved in property and tax administration. For questions regarding property tax, you can contact ADOR at (602) 255-3381. The Arizona State Board of Equalization (SBOE) handles appeals of property valuations and classifications, especially for properties in counties with larger populations. You can reach the SBOE at (602) 364-1600. Property owners can file a Petition for Review with the County Assessor within 60 days of the Notice of Valuation. The Arizona Board of Tax Appeals also hears cases concerning income, transaction privilege, sales, use, luxury, and estate taxes.
To appeal a property or tax decision in Arizona, first review your Notice of Valuation or tax assessment carefully. Gather all supporting evidence, such as comparable property sales, appraisals, or documentation of errors. File a Petition for Review with your County Assessor within the 60-day timeframe.
