In lieu of depositing tax payments in the United States mail, a licensed special fuel dealer, user or supplier may hand deliver said payment to the Department of Transportation or the Department may require licensed special fuel dealers, users or suppliers to make electronic transfers of such funds to the appropriate state account.
If a check received in payment of moneys due the Department under this subchapter shall be returned to the Department by the maker's bank because of insufficient funds, closed account, stopped payment or any other reason, there shall be imposed upon the maker a service charge of $10, and interest at the rate of 1 percent per month, or fraction thereof, shall accrue on the tax from the date such tax was due to be paid. A statement shall be sent to the maker demanding payment within 10 days of the original amount of the check plus the added service charge, penalty and interest, if any, and the cost of the postage incurred in mailing the statement, such amounts to be set forth in the statement. Failure of the maker to respond to the demand within 10 days shall constitute cause for the Department to suspend the maker's special fuel license, and 30 days after such suspension, if restitution has not been received, to revoke the maker's special fuel license.
