Except when an electronic fund transfer has been made under § 40.165a for the full amount of tax due, the tax on tobacco products shown to be due and payable on any return shall be paid by remittance in full with the tax return. The remittance may be in the form which the appropriate TTB officer is authorized to accept under § 70.61 of this chapter (Payment by check or money order) and which is acceptable to him, except as otherwise specified in § 40.166. Checks and money orders shall be made payable to the “Alcohol and Tobacco Tax and Trade Bureau”. In paying the tax, a fractional part of a cent shall be disregarded unless it amounts to one-half cent or more, in which case it shall be increased to one cent.
