Mineral royalties-proportional severance tax refunds.

Wyoming's HB 163 creates refunds for oil, gas, and coal producers on federal mineral estates when federal royalty rates increase. Starting January 1, 2024, eligible producers (on a per-property basis) receive refunds equal to 75% of the increased federal royalty impact, calculated using the state's share under federal law. Producers must apply annually by July 1 to receive refunds, which are funded from state severance tax distributions. The bill specifies the refund calculation method and distribution process without changing existing tax rates.
