      Sec. 12-414. Returns and payment. (1) Due date; exception. The taxes imposed 
by this chapter are due and payable to the commissioner monthly on or before the last 
day of the month next succeeding each monthly period except that every person whose 
total tax liability for the twelve-month period ended on the preceding June thirtieth was 
less than four thousand dollars shall file returns on a quarterly basis. "Quarterly" means 
a period of three calendar months commencing on the first day of January, April, July 
or October of each year or, if any seller commences business on a date other than the 
first day of January, April, July or October, a period beginning on the date of commencement of business and ending on March thirty-first, June thirtieth, September thirtieth or 
December thirty-first, respectively.
      (2) Return. On or before the last day of the month following each monthly or 
quarterly period, as the case may be, a return for the preceding period shall be filed with 
the commissioner in such form as the commissioner may prescribe. For purposes of the 
sales tax a return shall be filed by every seller. For purposes of the use tax a return shall 
be filed by every retailer engaged in business in the state and by every person purchasing 
services or tangible personal property, the storage, acceptance, consumption or other 
use of which is subject to the use tax, who has not paid the use tax due a retailer required 
to collect the tax, except that every person making such purchases for personal use or 
consumption in this state, and not for use or consumption in carrying on a trade, occupation, business or profession, need file only one use tax return covering purchases during 
a calendar year. Such return shall be filed and the tax due thereon paid on or before the 
fifteenth day of the fourth month succeeding the end of the calendar year for which such 
return is filed. Returns shall be signed by the person required to file the return or by his 
authorized agent but need not be verified by oath, provided a return required to be filed 
by a corporation shall be signed by an officer of such corporation.
      (3) Contents of return. For purposes of the sales tax the return shall show the gross 
receipts of the seller during the preceding reporting period. For purposes of the use tax, 
in case of a return filed by a retailer, the return shall show the total sales price of the 
services or property sold by him, the storage, acceptance, consumption or other use of 
which became subject to the use tax during the preceding reporting period; in case of a 
return filed by a purchaser, the return shall show the total sales price of the service or 
property purchased by him, the storage, acceptance, consumption or other use of which 
became subject to the use tax during the preceding reporting period. The return shall 
also show the amount of the taxes for the period covered by the return in such manner 
as the commissioner may require and such other information as the commissioner deems 
necessary for the proper administration of this chapter. The Commissioner of Revenue 
Services is authorized in his discretion, for purposes of expediency, to permit returns 
to be filed in an alternative form wherein the person filing the return may elect to report 
his gross receipts, including the tax reimbursement to be collected as provided for herein, 
as a part of such gross receipts or to report his gross receipts exclusive of the tax collected 
in such cases where the gross receipts from sales have been segregated from tax collections. In the case of the former, ninety-four and three-tenths per cent of such gross 
income may be considered to be the gross receipts from sales exclusive of the taxes 
collected thereon.
      (4) Filing return. Returns, together with the amount of the tax due thereon, shall 
be filed with the Commissioner of Revenue Services.
      (5) Return periods. The commissioner, if he deems it necessary in order to insure 
payment to or facilitate the collection by the state of the amount of taxes, may permit 
or require returns and payment of the amount of taxes for other than monthly or quarterly 
periods.
      (6) Extension of time. The commissioner for good cause may extend the time for 
making any return and paying any amount required to be paid under this chapter, if a 
written request therefor is filed with the commissioner together with a tentative return 
which must be accompanied by a payment of the tax, which shall be estimated in such 
tentative return, on or before the last day for filing the return. Any person to whom an 
extension is granted shall pay, in addition to the tax, interest at the rate of one per cent 
per month or fraction thereof from the date on which the tax would have been due 
without the extension until the date of payment.
