It’s a standard by which roughly 584 Centrally Valued Property (CVP) Taxpayers are mandated to self report their property value to AZDOR.

4. What Are Tax area codes?
Geographic areas whose boundaries are driven by:
School District Boundaries
City Boundaries
Special District Boundaries (Fire, Water, Etc.)
Tax area codes cover the whole state
Wide range in size
Over 1,000 square miles versus one parcel in size
Each tax area code has a 4 digit number & a unique set of districts

5. Tax Area codes are dynamic - Annexations
Cities, school districts, fire districts and special districts always annexing
By law districts must notify AZDOR of any boundary changes
AZDOR required to notify CVP taxpayers of tax area code changes

6. Tax Area codes - Distributing the Information
Distribute tax area code data in various ways
In the past hard copy map books
Now we send CVP taxpayers GIS files and/or electronic maps
In the future develop GIS applications to distribute the information
Sometimes CVP taxpayers share data with us
