Delaware Code
Subchapter I. Gasoline
§ 5113. Monthly reports of distributors.

(a) On or before the twenty-fifth day of each calendar month, each distributor of gasoline shall file with the office of the Department of Transportation, a statement on a form prepared by the Department of Transportation, which shall show the quantity of gasoline on hand on the first and last days of the preceding calendar month, the quantity of gasoline received, produced, manufactured, refined or compounded during the preceding calendar month, the quantity of gasoline sold, delivered or used within this State during the preceding calendar month, and such other information as the Department of Transportation may require. Aviation gasoline shall be reported separately from other gasolines.
(b) On or before June 25 each year, distributors having average monthly taxable sales and/or use of 500,000 or more gallons shall file a statement of the estimated sales and/or use anticipated for the same calendar month.
(c) The fact that a distributor's name is signed to such statements shall be prima facie evidence for all purposes that the reports were actually signed by such distributor or a duly authorized agent. Such statements shall contain a declaration by the person making the same, to the effect that the statements contained therein are true and are made under penalties of perjury, which declaration shall have the same force and effect as a verification of the return and shall be in lieu of such verification.
(d) The monthly statements or payments of tax, as provided in § 5114 of this title, shall be considered to have been duly and timely filed if such statements or payments are deposited in the United States mail with postage prepaid on or before the twenty-fifth day of a given calendar month; provided, however, that for good cause the Department of Transportation may grant a licensee a reasonable extension of time.
In lieu of depositing tax payments in the United States mail, a licensed motor fuel distributor may hand deliver said payment to the Department of Transportation or the Department may require licensed motor fuel distributors to make electronic transfers of such funds to the appropriate state account.
(e) When the twenty-fifth day of a given month falls on a weekend or state holiday, the due date of the statement and tax shall be the next following business day of the State.
