Maricopa County Issues Valuations Driving 2026 Property Taxes | The Locally Times
The Feb. 23 data release details median value changes for residential, commercial, and land parcels, providing the foundation for upcoming tax rate decisions by cities and school districts.
The Maricopa County Assessor's Office published its 2026 property valuation reports on February 23, providing the assessed values that will shape future property tax bills. The data, posted on the Assessor's website, includes key documents such as the '2025-2026 Full Cash Value Analysis' and the '2026 Median Change by Type' report. These reports provide year-over-year comparisons and break down value shifts across different property categories, which local governments, school districts, and other taxing authorities will use to set upcoming budgets and tax rates. ## Reports Break Down Value Changes by Area, Type The reports provide property value information broken down by geographic area and property type. Separate documents detail values for '2026 Single Family Residential By City' and '2026 Single Family Residential By Zip,' offering a granular view of the housing market. Similar reports cover '2026 Commercial By City' and '2026 Land By City.' This level of detail allows for analysis of how property valuations have changed in specific neighborhoods. The '2026 Median Change by Type' report summarizes these shifts, though public records do not yet quantify which property type—residential, commercial, or undeveloped land—saw the largest change in value. The release also includes the '2026 February State Abstract,' a comprehensive data file. ## How Valuations Impact Tax Rates and Budgets The Assessor’s data is a foundational component of local government finance. The release includes summary reports that directly impact how property taxes are calculated, including the '2026 City Levy Limit Summary,' '2026 School Summary,' and '2026 Fire District Levy Summary.' These documents establish the valuation base and levy limits for municipalities and special taxing districts. City councils, school boards, and fire district boards will use this information in their upcoming budget processes to set property tax rates. An individual’s final tax bill is determined by the assessed value of their property multiplied by the tax rates set by all applicable jurisdictions. ## Owners Can Opt for Electronic Valuation Notices In addition to summary reports, the Assessor’s Office sends individual Notices of Valuation to every property owner. Property owners can opt to receive these notices electronically through the county's eNotices service, an optional program intended to reduce county printing and postage costs. To register for electronic notices, a property owner must create an account and provide a parcel-specific authorization code. The Assessor's Office notes this unique code is located on the most recent Valuation Notice mailed to the property owner. Residents with questions about the service can contact the Assessor's office by phone or email.
