December 2025 Tax Deadlines for Businesses

As December approaches, business owners must remain vigilant with key tax obligations to close out the fiscal year effectively. Prioritizing corporate estimated tax payments and fulfilling monthly payroll tax deposits should be high on the agenda.

December 15 - Corporations' Estimated Tax

Corporations operating on a calendar year must make the fourth installment of their estimated tax payments for 2025 by this date, ensuring they remain compliant and avoid potential penalties.

December 15 - Employer Payroll Taxes

Employers subject to monthly deposit rules must remit payments for Social Security, Medicare, and income tax withholdings for November 2025 by December 15. This date also marks the due date for nonpayroll withholding deposits.

December 31 - Act Before Year-EndImage 3

Ensure that any year-end financial strategies are executed before December 31, given that many institutions may close early or be closed entirely. Plan ahead to avoid last-minute challenges and ensure all necessary transactions and filings are completed.

Considerations for Holidays and Weekends:

Deadlines landing on weekends or legal holidays extend to the next business day, allowing more leeway. Business owners should plan accordingly to avoid inadvertent lapses in compliance.

Disaster-Related Extensions

In geographical areas classified as disaster zones, businesses may qualify for extended deadlines. To check for any applicable extensions, visit the FEMA and IRS websites for the latest updates on areas with designated disaster relief.
