Essential November 2025 Tax Deadlines for Businesses

As the holiday season approaches, it's easy to get caught up in festive planning and year-end responsibilities. However, it's crucial to keep an eye on your business tax obligations in November, a pivotal month for many companies. In particular, taxes related to Form 941 and associated deposits are due this month. Staying on top of these deadlines is essential for avoiding penalties and ensuring smooth operations.

November 10 - File Form 941 for Q3 of 2025

By November 10, employers need to file Form 941 for the third quarter of 2025. This deadline is relevant if you've fully and timely deposited all taxes for the quarter. Missing this deadline could potentially lead to unwanted penalties or IRS complications. So mark your calendars accordingly to ensure compliance!

If your business follows the monthly deposit schedule, remember that November 17 is when you need to pay Social Security, Medicare, and withheld income tax for October 2025.

Weekend and Holiday Extensions

One of the silver linings for busy entrepreneurs is that if a tax deadline lands on a weekend or legal holiday, the due date props over to the next business day. Keep this in mind to manage your schedule effectively.

Extensions for Disaster Areas

Businesses located in federally designated disaster areas are eligible for extended tax deadlines. If you believe this applies to your business, check the FEMA disaster declarations and the IRS tax relief in disaster situations for more details on applicable extensions.
