Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Maricopa County Assessor's Office.
Relief programs
The filing guidance for this county is: February 28, 2026 for personal exemptions; a waiver may extend filing to September 1, 2026. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationSenior Valuation Protection: age 65 or older, primary residence for at least 2 years, and statutory income limits; application due September 1, 2026. Approved protection freezes LPV for three years, not the tax bill.
Arizona's Limited Property Value (LPV) is generally restricted to a 5% annual increase; statutory exceptions, including qualifying new construction, may produce a larger increase.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: April 21, 2026 for the 2027 real-property Notice of Value appeal deadline (2027 NOV mailed February 20, 2026). If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
