Key Tax Deadlines in November 2025 for Businesses

November quickly fills up with year-end accounting projects and festive plans, making it essential for accountants and business owners to prioritize essential tax deadlines. Image 1 Ensure compliance by marking these crucial dates on your calendar.

November 10 - Quarterly Payroll Taxes (Form 941)
By this date, you must file Form 941 for the third quarter of 2025, but only if you've settled the complete tax amount for the quarter in a timely manner.

November 17 - Monthly Payroll Taxes for October
If you follow the monthly deposit schedule as an employer, ensure Social Security, Medicare, and withheld income taxes for October 2025 are deposited by November 17. The same applies to monthly nonpayroll deposits. Image 2

Handling Weekends and Holidays

Note that if any due date coincides with a weekend or legal holiday, the IRS extends it to the next business day.

Disaster Area Filing Extensions
If the IRS or FEMA designates your location as a disaster area, affected tax due dates are extended correspondingly. You can verify declarations and extensions by visiting:

FEMA: https://www.fema.gov/disaster/declarations
