November 10 - Quarterly Payroll Tax Filings

By November 10, employers must file Form 941 for the third quarter of 2025. This deadline applies if all taxes for the quarter were fully paid on time. It's a critical step in meeting payroll tax obligations, ensuring your compliance with federal requirements.

November 17 - Monthly Payroll and Nonpayroll Deposit

If your business follows the monthly deposit schedule, ensure that Social Security, Medicare, and withheld income taxes for October 2025 are deposited by November 17. Additionally, the same deadline applies for the nonpayroll withholding deposits for October under the monthly rule, crucial for maintaining adherence to Treasury Department regulations.

Adjustments for Weekends & Holidays

It's important to note that if any deadline falls on a weekend or a public holiday, it extends to the next working day. This provision helps businesses plan their schedules without the worry of missing a compliance date.

Disaster Relief Provisions

In cases where a geographic area is designated as a disaster area, the IRS provides extensions. For updated information on disaster-specific dates, please refer to FEMA's Disaster Declarations and the IRS's Tax Relief in Disaster Situations pages.

Staying informed and proactive with your business tax calendar ensures smooth operations, especially in the final months of the fiscal year.
