November 10 - Quarterly Return of Social Security, Medicare, and Withheld Income Tax
By November 10, ensure that Form 941 for the third quarter of 2025 is filed. This deadline applies only if you've completed your tax deposits for the quarter accurately and on time.

November 17 - Monthly Deposit for Social Security, Medicare, and Withheld Income Tax
If you're an employer subject to the monthly deposit rules, November 17 is your key deadline for depositing Social Security, Medicare, and withheld income tax for October 2025. Additionally, this is the due date for nonpayroll withholding deposits if the monthly rules apply.
