What is my filing frequency?
Each year the Department determines withholding filing requirements based on an annual review of your account during the 12-month period of July 1 through June 30. For example, for the 2021 calendar year, we will look at the period July 1, 2019 through June 30, 2020. This is called a "look back period".
If the amount of Wage Withholding Tax remitted requires a more frequent filing schedule, the Department will notify the employer before January of the next calendar year. If the employer is eligible to file less frequently the Department will not change the filing status, the employer must request this change. Upon request, the Department will analyze your account to see if you are eligible. You must continue to file at your current frequency until we notify you of this change.
Withholding tax must be deducted and paid in whole dollar amounts. To determine filing frequency, estimate the amount of withholding tax that the business will expect to pay for all employees in one year. Based on that estimation the filing frequency for a new account will be as follows:
