Effective January 1, 2014, the withholding tax reporting and payment due dates for split-monthly filers will change.
A split-monthly filer is an employer whose withholding equals or exceeds $240,000 in a 12-month period or equals or exceeds $20,000 per month. Under current law, split-monthly filers pay withheld income tax based on a reporting period that begins on the 16th day of the month and ends on the 15th day of the next month and make payments by the 20th day of that same month.
For withholding periods beginning on or after January 1, 2014, the first withholding period will begin on the first day of the month and end on the 15th day of the month. Payments of withheld tax will be made no later than the 20th day of the same month. The second withholding period will begin on the 16th day of the month and end on the last day of the month. Withholding payments will be made no later than the fifth day of the following month.
