(1) Cannabis retailer licensees must submit monthly report(s) and payments to the WSLCB. The required monthly reports must be:

(a) On a form or electronic system designated by the WSLCB;

(b) Filed every month, including months with no activity or payment due;

(c) Submitted, with payment due, to the WSLCB on or before the 20th day of each month, for the previous month. (For example, a report listing transactions for the month of January is due by February 20th.) When the 20th day of the month falls on a Saturday, Sunday, or a legal holiday, the filing must be postmarked by the U.S. Postal Service no later than the next postal business day;

(d) Filed separately for each cannabis license held; and

(e) All records must be maintained and available for review for a three-year period on licensed premises (see WAC 314-55-087).

(2) Cannabis producer licensees: On a monthly basis, cannabis producers must maintain records and report purchases from other licensed cannabis producers, current production and inventory on hand, sales by product type, and lost and destroyed product in a manner prescribed by the WSLCB. The act of keeping data completely up-to-date in the state traceability system fulfills the monthly reporting requirement.

(3) Cannabis processor licensees: On a monthly basis, cannabis processors must maintain records and report purchases from licensed cannabis producers, other cannabis processors, production of cannabis-infused products, sales by product type to cannabis retailers, and lost and/or destroyed product in a manner prescribed by the WSLCB. The act of keeping data completely up-to-date in the state traceability system fulfills the monthly reporting requirement.

(4) Cannabis retailer's licensees:

(a) On a monthly basis, cannabis retailers must maintain records and report purchases from licensed cannabis processors, sales by product type to consumers, and lost and/or destroyed product in a manner prescribed by the WSLCB.

(b) A cannabis retailer licensee must collect from the buyer and remit to the WSLCB a cannabis excise tax of 37 percent of the selling price on each retail sale of useable cannabis, cannabis concentrates, and cannabis-infused products.

(c) Product inventory reductions that are not adequately documented will be deemed to be sales and will be assessed the excise tax.

(d) Excise tax collected in error must either be returned to the customer(s) or remitted to the WSLCB if returning to the customer(s) is not possible.

(5) Payment methods: Cannabis excise tax payments are payable only by check, cashier's check, money order, or electronic payment or electronic funds transfer. Licensees must submit cannabis excise tax payments to the board by one of the following means:

(a) By mail to WSLCB, Attention: Accounts Receivable, P.O. Box 43085, Olympia, WA 98504;

(b) By paying through online access through the WSLCB traceability system; or

(c) By paying using a money transmitter licensed pursuant to chapter 19.230 RCW. If a licensee uses a money transmitter service, the licensee must remit payments in U.S. dollars.

(6) Payments transmitted to the board electronically under this section will be deemed received when received by the WSLCB's receiving account. All other payments transmitted to the WSLCB under this section by United States mail will be deemed received on the date shown by the post office cancellation mark stamped on the envelope containing the payment.

(7) The WSLCB may waive the means of payment requirements as provided in subsection (5) of this section for any licensee for good cause shown. For the purposes of this section, "good cause" means the inability of a licensee to comply with the payment requirements of this section because:

(a) The licensee demonstrates it does not have and cannot obtain a bank or credit union account or another means by which to comply with the requirements of subsection (5) of this section and cannot obtain a cashier's check or money order; or

(b) Some other circumstance or condition exists that, in the WSLCB's judgment, prevents the licensee from complying with the requirements of subsection (5) of this section.

(8) If a licensee tenders payment of the cannabis excise tax in cash without applying for and receiving a waiver or after denial of a waiver, the licensee may be assessed a 10 percent penalty.

(9) If a licensee is denied a waiver and requests an adjudicative proceeding to contest the denial, a brief adjudicative proceeding will be conducted as provided under RCW 34.05.482 through 34.05.494.

(10) For the purposes of this section, "electronic payment" or "electronic funds transfer" means any transfer of funds, other than a transaction originated or accomplished by conventional check, drafts, or similar paper instrument, which is initiated through an electronic terminal, telephonic instrument, or computer or magnetic tape so as to order, instruct, or authorize a financial institution to debit or credit a checking or other deposit account. "Electronic funds transfer" includes payments made by electronic check (e-check).
