Delaware Withholding Tax Requirements

PLEASE NOTE:

  • Failure to choose the correct form for your filing frequency will delay the processing of your return. If you are not sure of your filing frequency, please call 302-577-8779.
  • Payments must be made separately for each entity. Do not remit payments under one identification number and then submit W3, W2, or 1099 forms for multiple identification numbers.

The annual form, accompanied by copies of Forms W-2, is due on or before the last day of January of the following year, or on or before the 30th day from the date on which the last payment of wages was made.
