      Sec. 12-268d. Failure to pay tax when due. Penalty provisions. (a) If any company included in section 12-249, 12-256, 12-264 or 16-331cc, or municipal utility, as 
defined in section 12-265, fails to pay the amount of tax reported to be due on its return 
within the time specified under the provisions of chapter 210, 211, 212 or this chapter 
or section 16-331cc, there shall be imposed a penalty equal to ten per cent of such amount 
due and unpaid, or fifty dollars, whichever is greater. Such amount shall bear interest 
at the rate of one per cent per month or fraction thereof, from the due date of such tax 
until the date of payment.
      (b) If any company or municipal utility has not made its return within one month 
after the time specified in section 12-249, 12-256, 12-264 or 16-331cc, the commissioner 
may make such return at any time thereafter, according to the best information obtainable 
and according to the form prescribed. To the tax imposed upon the basis of such return, 
there shall be added an amount equal to ten per cent of such tax, or fifty dollars, whichever 
is greater. The tax shall bear interest at the rate of one per cent per month or fraction 
thereof, from the due date of such tax until the date of payment. No taxpayer shall be 
subject to a penalty under both subsections (a) and (b) of this section in relation to the 
same tax period.
      (c) Subject to the provisions of section 12-3a, the commissioner may waive all or 
part of the penalties provided under this chapter when it is proven to his satisfaction 
that the failure to pay any tax was due to reasonable cause and was not intentional or 
due to neglect.
