Notwithstanding any other provision of this chapter, a dealer may be required by the Tax Commissioner to file sales or use tax returns on an accounting period less frequent than monthly when, in the opinion of the Tax Commissioner, the administration of the taxes imposed by this chapter would be enhanced. If a dealer is required to file other than monthly, each such return shall be due on or before the twentieth day of the month following the close of the period. Each such return shall contain all information required for monthly returns.
A sales or use tax return shall be filed by each registered dealer even though the dealer is not liable to remit to the Tax Commissioner any tax for the period covered by the return.
The Tax Commissioner shall not require that more than one sales and use tax return per month be filed with the Department by any remote seller or any software provider on behalf of such remote seller.
