Key December 2025 Tax Deadlines for Businesses

As we approach the end of the year, December presents critical tax deadlines for business owners to keep in mind. These include the payment of corporate estimated taxes and monthly payroll obligations. Take a proactive approach to year-end planning and ensure you've completed necessary actions ahead of December 31 closures.

December 15 - Corporate Estimated Tax Payments

Businesses operating on a calendar year must finalize the fourth installment of their corporate estimated taxes for 2025 by December 15. It's crucial to ensure these payments are timely to avoid penalties and maintain optimal cash flow management.Image 2

December 15 - Payroll Tax Obligations

Employers bound by the monthly deposit rules must deposit Social Security, Medicare, and withheld income tax for November 2025 by December 15. This date also applies to November's nonpayroll withholding deposits, if the monthly rule is applicable. Ensure compliance to sidestep unnecessary scrutiny and penalties.Image 1

December 31 - Year-End Planning Reminder

December 31 marks the final opportunity to execute year-end tax strategies. If any actions require more than a day to complete, begin earlier to counteract holiday closures. Prioritize these tasks to maximize tax efficiency and avoid end-of-year stress.

Holiday and Weekend Extensions:

Should a deadline land on a weekend or a legal holiday, it automatically extends to the next available business day. This provision ensures that taxpayers aren’t rushed under such circumstances. 

Extensions for Disaster Areas:

Taxpayers in areas recognized as disaster zones by FEMA have extended deadlines. For specifics on these extensions, consult the following resources:
FEMA: FEMA Disaster Declarations
IRS: IRS Tax Relief for Disasters
