The due dates for income tax withholding reports vary for employers filing monthly, quarterly, accelerated and annual reports. If the due date falls on a Saturday, Sunday or state holiday, the report is due on the next business day.
Monthly income tax withholding reports are due on the 15th day of the month following the month in which the income tax was withheld.
If you are required to file monthly withholding reports you must continue to file reports until you give written notice to the Comptroller of Maryland indicating that you no longer have employees or are no longer liable to file the return.
Quarterly income tax withholding returns are due on the 15th day of the month that follows a calendar quarter in which income tax was withheld.
If you are required to file quarterly, you must continue to file reports until you give written notice to the Comptroller of Maryland indicating that you no longer have employees or are no longer liable to file the return.
Employers filing accelerated withholding reports must file within three business days following the payroll (pay date).
The accelerated filing category applies to employers who withheld $15,000 or more for the preceding calendar year and currently have accumulated in any pay period $700 or more in withholding tax.
Employers filing annual reports must file on or before January 31 in the year that follows the year in which the income tax was withheld.
