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.
