Essential November 2025 Tax Deadlines for Businesses

As November heats up with end-of-year projects and holiday plans, it's crucial for business owners to keep a keen eye on upcoming tax deadlines. Ensuring compliance prevents potential penalties and secures your company's financial health as the year closes. This month’s focal point is the Form 941 submission along with your Social Security and Medicare deposits.

November 10 - Form 941 Deadline

File Form 941 for the third quarter of 2025. This deadline is solely for those who have already deposited their taxes for the quarter accurately and promptly. It's a straightforward but critical task in maintaining your business's standing with the IRS.

November 17 - Monthly Deposit Deadline

Employers adhering to the monthly deposit rules should ensure their deposits for Social Security, Medicare, and withheld income taxes for October 2025 are made by November 17. Additionally, if nonpayroll withholding rules apply for October, make sure those deposits are squared away. Ensuring these payments are on time maintains your business’s streak of financial integrity.

Weekend and Holiday Adjustments:

Be mindful that if any deadline lands on a weekend or recognized holiday, the due date is automatically extended to the next business day that is not a holiday. This is a simple yet often overlooked detail that can save you from unnecessary stress.
