Delaware Payroll Tax Deadlines Employers Should Track

Managing payroll taxes in Delaware requires careful attention to specific deadlines to ensure compliance and avoid penalties. Employers must stay organized with their payroll tax filings and payments throughout the year.

Key Payroll Tax Deadlines in Delaware

  • Federal Payroll Tax Deposits: Employers must follow the IRS deposit schedule, which may be semi-weekly or monthly depending on the total tax liability. Deposits are generally due by the next banking day after payday.
  • Delaware State Withholding Tax: Delaware requires withholding tax deposits on a monthly or semi-weekly basis depending on the amount withheld. Monthly deposits are due by the 20th of the following month. Semi-weekly deposits are due within three banking days after the payroll date.
  • Quarterly Payroll Tax Reporting: Employers must file IRS Form 941 quarterly. The due dates are generally April 30, July 31, October 31, and January 31 for the previous quarter.
  • Delaware Employer’s Quarterly Wage Report: This report is due quarterly, typically by the last day of the month following the end of the quarter (April 30, July 31, October 31, January 31).
  • Unemployment Insurance Tax Payments: Delaware employers pay unemployment insurance taxes quarterly. Payments and reports are due by the last day of the month following the end of each quarter.

Operational Recommendations
