Sales tax: exemptions; exemptions for the sale of investment coins and bullion; modify. Amends sec. 4s of 1933 PA 167 (MCL 205.54s). TIE BAR WITH: HB 5130'25, HB 5129'25

HB 5129 updates Michigan's sales tax law to exempt purchases of investment coins and bullion from tax. It expands the definition of "bullion" to include gold, silver, or platinum films/leafs (50%+ metal content) used as currency (but not legal tender) starting January 1, 2026, while maintaining the 90% purity standard for other bullion. This directly affects buyers of these specific precious metal products, including new film-based items, by removing sales tax. The bill requires passage of companion bill HB 5130 to take effect.
