(ZeroHedge) 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).

If taxpayers own gold to protect themselves against the devaluation of America's paper currency, they frequently end up with a "gain" when exchanging those metals back into dollars. However, this is not necessarily a real gain in terms of a gain in actual purchasing power. This "gain" is often a nominal gain because of the slow but steady devaluation of the dollar. Yet the government nevertheless assesses a tax.
