These categories shall be taxed at their relative value compared with cannabis flowers.

(d) The department may prescribe by regulation a method and manner for payment of the cultivation tax that utilizes tax stamps or state-issued product bags that indicate that all required tax has been paid on the product to which the tax stamp is affixed or in which the cannabis is packaged.

A cultivator’s liability for the tax is not extinguished until the tax has been paid to this state except that an invoice, receipt, or other document from a distributor or manufacturer given to the cultivator pursuant to paragraph (3) is sufficient to relieve the cultivator from further liability for the tax to which the invoice, receipt, or other document refers. Cannabis shall not be sold unless the tax has been paid as provided in this part.

The manufacturer shall remit the cultivation tax collected on the cannabis product sold or transferred to a distributor for quality assurance, inspection, and testing, as described in § 26110 of the Business and Professions Code. This paragraph shall not apply where a distributor collects the cultivation tax from a cultivator pursuant to paragraph (1).

(B) Notwithstanding subparagraph (A), the department may prescribe a substitute method and manner for collection and remittance of the cultivation tax under this paragraph, including a method and manner for collection of the cultivation tax by a distributor.

(3) A distributor or manufacturer shall provide to the cultivator, and a distributor that collects the cultivation tax from a manufacturer pursuant to paragraph (2) shall provide to the manufacturer, an invoice, receipt, or other similar document that identifies the licensee receiving the product, the cultivator from which the product originates, including the associated unique identifier, the amount of cultivation tax, and any other information deemed necessary by the department. The department may authorize other forms of documentation under this paragraph.

(4) The department may adopt regulations prescribing procedures for the refund of cultivation tax collected on cannabis or cannabis product that fails quality assurance, inspection, and testing as described in § 26110 of the Business and Professions Code.
