AZ HB2139

Amends Arizona Revised Statutes section 42-16051 to modify the petition process for property owners to challenge property tax valuations deemed too high or improper.

Requires property owners filing petitions with county assessors to provide substantial information justifying their opinion of property value, including specified valuation methods (income, market, or cost approach).

Allows petitioners using the market approach to provide evidence of fraudulent land sales that have artificially inflated real property values in a geographic area as an alternative to providing comparable property sales data.

Permits multiple parcels to be included in a single petition if they meet specified criteria including same economic unit, same owner, same use, same appeal basis, and same geographic area per department guidelines.

Maintains the existing 60-day filing deadline for petitions after assessor notice of valuation is mailed, delivered, or transmitted electronically.
