(a) An employer whose total liability for state income tax withholding during the preceding lookback period was $12,000 or more shall remit on an "accelerated schedule", which is the same as the employer's federal due dates for federal tax deposits.
(b) An employer whose total liability for state income tax withholding during the preceding lookback period was less than $12,000 but more than $1,199 shall remit on a "monthly schedule" for which the remittance due date is on or before the 15th day of the month following the payment of wages.
(c) An employer whose total liability for state income tax withholding during the preceding lookback period was less than $1,200 shall remit on an "annual schedule" for which the remittance due date is on or before January 31 of the year following payment of wages.
(d) An employer who has no withholding to remit for a remittance period shall, on or before the due date of the applicable remittance schedule, submit a payment coupon showing that a zero amount is being remitted.
(2) An employer who has not complied with the requirements of this section shall, upon written notice from the department, remit on the monthly schedule described in subsection (1)(b).
(3) On or before November 1 of each year, the department shall notify the employers subject to the provisions of this section of the employers' remittance schedules for the following calendar year based upon the department's review of the preceding lookback period.
(4) A new employer or an employer with no filing history is subject to the monthly remittance schedule in subsection (1)(b) until the department is able to determine the employer's proper remittance schedule by a review of the employer's first complete lookback period.
(5) An employer may elect to remit payments on a more frequent basis than is required by subsection (1).
(6) An employer may use alternative remittance methods in conjunction with the department's electronic remittance program in accordance with department rules.
