SACRAMENTO—Newly introduced legislation would expand the number of government offices where cannabis business owners can pay state fees and taxes, a nod to the safety issues inherent in what largely remains an all-cash industry.

The Cannabis Safe Payment Act, written by two state senators and sponsored by Board of Equalization chairwoman Fiona Ma, would allow California counties—with approval by individual boards of supervisors and tax collectors—to accept cannabis business payments for state bills. It would also allow the tax agency to collect payments on behalf of other state departments.
