However, no such adjustment shall decrease any tax imposed by this chapter, unless approved by the city council.

3.44.030 - Purpose, applicability, and operation of commercial cannabis tax.

B. The tax is in addition to all other taxes imposed by this Code, including, but not limited to, business license taxes pursuant to Title 5.

C. Neither establishment nor payment of the tax shall constitute or be construed as authorization of any commercial cannabis operation that is not authorized pursuant to Chapter 18.49. However, the tax is intended to apply both to commercial cannabis operations that are currently allowed under Chapter 18.49 and to any potential future commercial cannabis operations that the city council may subsequently allow by ordinance.

D. The city council may set and thereafter tax at lower rates than the maximum rates set forth in this chapter, may establish exemptions, incentives, or other reductions, may impose penalties and interest charges, and may make determinations of tax due for failure to pay the tax in a timely manner, to the fullest extent allowed under state law and this Code. No action by the city council under this section shall prevent the city council from later increasing or restoring the taxes to higher rates up to the maximum rates authorized by this chapter, or from removing or altering any exemption, incentive, reduction, or other action under this section, and no such action shall require voter approval.

E. The taxes imposed by this chapter are not sales or use taxes and shall not be calculated or assessed as such. The taxes shall not be separately identified or otherwise specifically assessed or charged to any individual, consumer or customer; rather, the taxes are imposed upon the commercial cannabis operation.

At the time the tax return is filed, the full amount of the tax owed for said calendar quarter shall be remitted to the city.

F. Notwithstanding any other provision of this chapter, if the date that would normally be the due date falls on a Friday, Saturday, Sunday, or a federal holiday, the due date shall be the next regular business day on which the city hall is open to the public following the date that would otherwise have been the due date.

F. The tax obligations imposed by this chapter shall commence on, and shall be calculated from, the effective date of this chapter.

G. The tax administrator may waive the penalties, but not the interest, imposed by this section upon any commercial cannabis operation if the commercial cannabis operation provides evidence satisfactory to the tax administrator that failure to pay the tax in a timely fashion was due to circumstances beyond the control of the operation and occurred notwithstanding the exercise of ordinary care and the absence of willful neglect, and the operation paid the delinquent tax and accrued interest owed to the city in full prior to applying to the tax administrator for a penalty waiver. Notwithstanding the foregoing, no such waiver pursuant to this section shall be granted more than once during any 24-month period.

If the tax administrator has insufficient information with which to determine entitlement to a refund, and the refund claimant refuses to allow examination of its books and business records as necessary to make such determination after request by the tax administrator, no refund shall be made for so long as, and to the extent that, the tax administrator lacks sufficient information to make the determination of entitlement.

F. The tax administrator shall initiate a refund of any tax which has been overpaid or erroneously collected whenever the overpayment or erroneous collection is identified by a city audit of tax receipts.

Any violation of any provision of this chapter or any administrative rule or regulation promulgated hereunder, and any knowing or intentional misrepresentation made to the tax administrator regarding any material fact concerning the operation or administration of this chapter or any obligation pursuant to this chapter, constitutes a misdemeanor.

D. It shall be the duty of the tax administrator to enforce each and all of the provisions of this chapter. The tax administrator shall have the power to audit and examine all books and records of commercial cannabis operations, including both state and federal income tax returns, California sales tax returns, logs, receipts, bank records, or other evidence documenting the proceeds of the operation, or any person engaged in the conduct of an operation, for the purpose of ascertaining the amount of tax, if any, required to be paid by the provisions of this chapter, and for the purpose of verifying any statement or representation made by any person pursuant to the provisions of this chapter. If any such person or operation, after written demand by the tax administrator, refuses to make available for audit, examination or verification such books, records, or equipment as requested, the tax administrator may, after full consideration of all information available to the tax administrator concerning the activities or operations of the refusing party, make a determination of tax due in the manner provided in Section 3.44.080.

B. If the tax administrator is not satisfied that a statement or representation made pursuant to this chapter is correct, or that the amount of tax required to be paid pursuant to this chapter is correctly computed, the tax administrator may compute and determine the amount due and make a deficiency determination upon the basis of any information in his or her possession or that may come into his or her possession. One or more deficiency determinations of the amount of tax due for a given reporting period may be made.

D. The notice of determination shall separately set forth the amount of any tax known or estimated by the tax administrator to be due under each applicable section of this chapter, after consideration of all information within the tax administrator's knowledge concerning the business and activities of the person assessed, and shall include the amount of any penalties or interest accrued on each amount to the date of the notice of determination.

E. The notice of determination shall be served upon the person either by handing it to him or her personally, or by depositing the notice in the United States mail, postage prepaid, addressed to the person at the address of the commercial cannabis operation appearing on the face of the business license issued to the person or operation under this Code or to such other address as he or she shall register with the tax administrator for the purpose of receiving notices provided under this chapter; or, should the person have no business license and no address registered with the tax administrator, then to such person's or operation's last known address of record. For purposes of this section, a service by mail is complete at the time of deposit in the United States mail.

F. Within ten days after the date of service of a notice of determination pursuant to this section, the person may apply in writing to the tax administrator for a hearing on the determination. If such application is not timely made, the tax assessed by the tax administrator shall become final and the right to a hearing shall be deemed waived and forfeited. If such application is timely made, the hearing shall be conducted in accordance with applicable law and the following:

  1. The city council hereby delegates its authority to conduct hearings pursuant to this section to an independent hearing officer. The compensation of the hearing officer shall not depend on any particular outcome of the appeal. The hearing officer shall have full authority and duty to preside over the hearing on the determination in the manner set forth herein and as required by law.

  3. Notice of the hearing shall be given by the tax administrator to the person requesting the hearing not later than five days prior to the date of the hearing. For good cause, the hearing officer may continue the hearing from time to time. At the hearing, the applicant may appear and offer evidence to show why the determination as made by the tax administrator should not be confirmed and fixed as the tax due. In conducting the hearing, the hearing officer shall not be limited by the technical rules of evidence. Failure of the person who applied for a hearing on the determination to appear shall not affect the validity of the proceedings or any order issued thereon.

  4. Upon conclusion of the hearing, or no later than ten days after the conclusion of the hearing, the hearing officer shall determine and reassess the proper tax to be charged and shall give written notice to the person in the manner prescribed in this chapter for giving notice of determination, and the hearing officer shall submit his or her decision and the record to the city clerk. The decision of the hearing officer shall be final.
