Rev. & Tax. Code, § 30168

(a) Except as provided for in subdivision (c), amounts owing for stamps and meter register settings purchased on the deferred-payment basis shall be due and payable based on the distributor’s election to make the payment pursuant to subdivision (b). Payment shall be made by a remittance payable to the board.

(b) A distributor shall elect to make the payment required by subdivision (a) on either a monthly, a twice-monthly, or a weekly basis. An election made pursuant to this subdivision shall remain in effect for at least one year from the date the election is made. If the board finds that good cause exists for a distributor’s inability to maintain the election for the full year, the board shall authorize the distributor to make a new election, as otherwise authorized by this subdivision, prior to the expiration of the one-year period following the prior election.

(1) If a distributor elects to make the payment required by subdivision (a) on a monthly basis, the distributor shall remit the payment on or before the 25th day of the month following the month in which the stamps and meter register settings were purchased.

(2) If a distributor elects to make the payment required by subdivision (a) on a twice-monthly basis, the distributor shall make two remittances during the month following the month in which the stamps and meter register settings were purchased. The first monthly remittance shall be made on or before the fifth day of the month and shall be equal to either one-half of the total amount of those purchases of stamps and meter register settings that were made during the preceding month or the total amount of those purchases of stamps and meter register settings that were made between the first day and the 15th day of the preceding month, whichever is greater. The second monthly remittance shall be made on or before the 25th day of the month for the remainder of those purchases of stamps and meter register settings that were made in the preceding month.

(3) If a distributor elects to make the payment required by subdivision (a) on a weekly basis, the distributor shall remit the payment on or before Wednesday following the week in which the stamps and meter register settings were approved and released. Every distributor electing to make payment on a weekly basis shall provide to the board and update, as necessary, an electronic mail address for the purpose of receiving payment information, including but not limited to, amounts owing for stamps and meter register settings purchased.

(c) Amounts owing for stamps and meter register settings purchased on the deferred-payment basis without a security pursuant to subdivision (d) of Section 30142 shall be due and payable on or before Wednesday following the week in which the stamps and meter register settings were purchased. Payment shall be made by a remittance payable to the board.
