Section 505. Returns

Every  carrier  subject  to  this article and every
  carrier to whom a certificate of registration was issued shall  file  on
  or before the last day of each month a return for the preceding calendar
  month  where  a carrier's total tax liability under this article for the
  preceding  calendar  year  exceeded  four  thousand  dollars.  Where   a
  carrier's  total  tax  liability  under  this  article for the preceding
  calendar year did not exceed four thousand dollars or  where  a  carrier
  was  not  subject  to  such  tax in the preceding calendar year, returns
  shall be filed quarterly, on or before the  last  day  of  the  calendar
  month  following  each  of the calendar quarters: January through March,
  April through June, July through September and October through December.
  Provided, however, if the commissioner consents thereto in writing,  any
  carrier may file a return on or before the thirtieth day after the close
  of  any different period, if the carrier's books are regularly kept on a
  periodic basis other than a calendar month or quarter. The  commissioner
  may  permit  the  filing  of  returns  on  an annual basis, provided the
  carrier was subject to the tax under  this  article  during  the  entire
  preceding calendar year and the carrier's total tax liability under this
  article  for  such  year  did not exceed two hundred fifty dollars. Such
  annual returns shall be filed on or before January thirty-first  of  the
  succeeding  calendar  year. Returns shall be filed with the commissioner
  on forms to be furnished by such commissioner for such purpose and shall
  contain such data, information or matter as the commissioner may require
  to be included therein. The fact that a carrier's name is  signed  to  a
  filed  return  shall  be  prima facie evidence for all purposes that the
  return was actually signed by such carrier. The commissioner may grant a
  reasonable extension of time for  filing  returns  whenever  good  cause
  exists  and  may waive the filing of returns if a carrier is not subject
  to the tax imposed by this article for the period covered by the return.
  Every return shall have annexed thereto a certification  to  the  effect
  that the statements contained therein are true.
