      Sec. 12-416. Assessments if no return made. (a) Assessment; failure to file return. If any person fails to make a return, the commissioner shall make an estimate of 
the amount of the gross receipts of the person or, as the case may be, of the amount of 
the total sales price of services or tangible personal property sold or purchased by the 
person, the storage, acceptance, consumption or other use of which in this state is subject 
to the use tax. The estimate shall be made for the period or periods in respect to which 
the person failed to make a return and shall be based upon any information which is in 
or may come into the commissioner's possession. To the tax imposed upon the basis of 
such estimate, there shall be added an amount equal to fifteen per cent of such tax, or 
fifty dollars, whichever is greater. No person shall be subject to a penalty under both 
this section and section 12-419. Except in the case of new information that may come 
into the commissioner's possession, the commissioner may not make more than one 
assessment for a tax period for which a tax return has not been filed.
      (b) Interest. The amount of the assessment shall bear interest at the rate of one per 
cent per month or fraction thereof from the last day of the month succeeding the period 
for which the amount or any portion thereof should have been returned until the date 
of payment.
      (c) Notice of assessment. Promptly after making the assessment the commissioner 
shall give to the person written notice of the estimate, assessment and penalty, the notice 
to be served personally or by mail in the manner prescribed for service of notice of a 
deficiency assessment.
