Article 1. Returns And Payments of California Revenue And Taxation Code >> Division 2. >> Part 3. >> Chapter 4. >> Article 1.

The excise tax imposed by this part is due and payable quarterly on or before the last day of the calendar month next succeeding each quarterly period in which a taxable use of fuel occurs.

If any user has paid the tax to a vendor who is the holder of a valid vendor's permit issued under this part, he shall be allowed a credit against the amount of tax due under Section 8751 with respect to that fuel on which the tax was paid to the vendor.

(a) Except as provided in subdivision (b), on or before the last day of the calendar month following each quarterly period, every user shall, except as otherwise provided in Section 8608, file with the board a return in the form as prescribed by the board, which may include, but not be limited to, electronic media showing the amount of any tax due and any other information as the board may require to carry out the purposes of this part. Returns shall be authenticated in a form or pursuant to methods as may be prescribed by the board.
  (b) This section shall not be applicable to any user whose sole use of fuel subject to the tax imposed by this part is for the propulsion of a privately operated passenger automobile, provided that the fuel used in this state, except fuel brought into this state in the fuel tank of the vehicle, is purchased from and delivered into the fuel tank of the vehicle by a vendor holding a permit issued under this part.

The user shall accompany each return with a remittance payable to the board for the amount of tax due.

The board for good cause may extend for not to exceed one month the time for making any return or paying any tax required under this part. The extension may be granted at any time; provided, a request therefor is filed with the board within or prior to the period for which the extension may be granted. Any user to whom an extension is granted shall pay, in addition to the tax, interest at the modified adjusted rate per month, or fraction thereof, established pursuant to Section 6591.5, from the date on which the tax would have been due without the extension to the date of payment.

The board, if it deems it necessary in order to ensure payment of the tax imposed by this part, or to facilitate the administration of this part, may require returns and payment of the tax to be made for designated periods other than quarterly periods. On or before the last day of the calendar month following each designated period, a return for the preceding designated period shall be filed with the board in any form as the board may prescribe.
