213. An employer that fails to send a statement pursuant to section 21 or 33, or that fails to pay an assessment within the prescribed time limit, is required to pay interest to the Commission.
The interest is determined as follows:(1) where the employer fails to send a statement to the Commission within the prescribed time under section 21 or 33, interest is payable on the assessment determined on the basis of the insurable wages that are declared late or evaluated pursuant to section 307 of the Act, as well as on the penalty imposed pursuant to section 321.2 or 321.3 of the Act, if any. The interest is calculated from the day following the date prescribed for filing the statement to the day on which the statement is received by the Commission;
(2) where the employer fails to pay an assessment, a penalty or interest within the prescribed time, interest is payable on the outstanding balance appearing on the assessment notice and is calculated from the day following the date on which the notice is issued to the 20th day of the following month. For each subsequent month, if the failure persists, interest is payable on the balance outstanding on the 21st day of that subsequent month, and is calculated from the 21st day of the preceding month to the 20th day of the subsequent month.
