Appeals

The Assessor’s Office mailed 2023 Notices of Value on two dates: February 25th and February 28th. Notices mailed on February 25th have an appeal deadline of April 26th. Notices mailed on February 28th have an appeal deadline of April 29th. The appeal deadline date for each parcel is displayed on the Parcel Detail page for that parcel (search for your parcel and click on the APN). If you have any questions about your parcel, or if you did not receive your 2023 notice, please contact us at AssessorRD@maricopa.gov or 602-506-3797.

Update: 2,370 specific parcels received an amended Notice of Value that was mailed on April 22nd. Only these specific parcels have an appeal deadline of June 21st. If you received one of these notices and would like to appeal, please complete a Residential Petition for Review of Valuation on the AZDOR website.
