Sound money advocates scored a major victory on Wednesday, when the Arizona state senate voted 16-13 to remove all income taxation of precious metals at the state level. The measure heads to Governor Doug Ducey, who is expected to sign it into law. Under House Bill 2014, introduced by Representative Mark Finchem (R-Tucson), Arizona taxpayers will simply back out all precious metals “gains” and “losses” reported on their federal tax returns from the calculation of their Arizona adjusted gross income (AGI).
