Essential November 2025 Tax Deadlines for Businesses

As November transitions into a frenzy of year-end projects and holiday commitments, it's crucial not to lose sight of key business tax obligations. Staying ahead of Form 941 and pertinent deposit deadlines will ensure a smoother financial close to the year.

November 17 - Social Security, Medicare, and Withheld Income Tax

If monthly deposit rules apply to your business, mark November 17 as the due date for October 2025 deposits covering Social Security, Medicare, and withheld income taxes. Similarly, the nonpayroll withholding deposit, if following the monthly deposit rule, is due then as well.

Considerations for Weekends & Holiday Extensions:

Extensions in Disaster Scenarios:

Be aware that IRS provisions allow for deadline extensions if your geographical area has been recognized as a disaster zone. Check current statuses and extension details through the following resources:
