The quarters are as follows:

  • Quarter 2 (Q2): April 1 - June 30
  • Quarter 3 (Q3): July 1 - September 30
  • Quarter 4 (Q4): October 1 - December 31

The following sections outline important quarterly filing dates.

March 31, June 30, September 30, December 31

March 31, June 30, September 30, and December 31 are the last days of their respective quarters.

Any paycheck dated within the quarter (regardless of the pay-period ending date) will be included in your first quarter 941 and state tax filings.

April 30, July 31, October 31, and January 31

April 30, July 31, October 31, and January 31 are the due dates for the following:

  • Deadline for filing Federal Form 941 
    Form 941 filings are due on the last day of the month following the end of the quarter. This does not affect your scheduled tax payment for 941.
    See Instructions for Form 941 for additional information
  • Deadline for filing most State Tax forms
    Most state quarterly filings are due on the last day of the month following the end of the quarter. To verify the filing deadline in your state, visit our Payroll Tax Compliance website, select your State, and, on the Tax Forms tab, select the View link next to the State Forms to see the filing due dates.
Tip The end of the quarter is a busy time for tax agencies, so submitting or e-filing your tax forms before the deadline is a good idea.
