legal tender; uses

HB 2088 defines "legal tender" in Arizona to include gold and silver coins/bullion meeting specific purity standards (0.999 for both), alongside U.S. currency. It prohibits compelling others to use such precious metals for payments (only allowing voluntary adoption) and exempts all transactions involving this "specie" from state taxes like income, sales, or property taxes. The bill requires tax payments involving precious metals to be made in equivalent specie or legal tender, using real-time market rates from approved services, and directs the state treasurer to create valuation guidelines. This directly affects Arizona residents, businesses, and financial institutions engaging in transactions using gold or silver as payment.
