November 17 - Employer's Monthly Tax Deposit

For employers adhering to monthly deposit rules, November 17 marks the due date for settling Social Security, Medicare, and withheld income taxes for October 2025. Additionally, nonpayroll withholding deposits for the same period should also be concluded by this date.

Handling Weekends & Holidays:

Should any deadline land on a weekend or public holiday, the IRS provides the courtesy of extending your due date to the subsequent business day that is free of legal holidays. This flexibility serves to accommodate unforeseen scheduling conflicts that may arise during these periods.
