November 17 - Employer Deposits

If you are an employer governed by the monthly deposit rules, make sure to deposit Social Security, Medicare, and withheld income taxes for October 2025 by this date. Additionally, if the monthly deposit rule pertains to your business, nonpayroll withholding for October 2025 is due.

Weekends & Holidays:

Remember that if a due date lands on a weekend or a public holiday, deadlines roll over to the next business day. Strategize your tax submissions in advance to avoid last-minute rushes.

Disaster Area Extensions:

In scenarios where a region is declared a disaster area, tax deadlines are extended. For details on disaster declarations and deadline extensions, consult the following useful links:
