Essential December 2025 Tax Deadlines for Your Business

As the year comes to a close, it’s crucial for business owners to wrap up 2025 with smart financial strategies. This month’s tax reminders focus on key due dates for optimizing your tax outcome, including year-end tax planning, tip reporting, mandatory IRA withdrawals, and final deductible payments. Stay ahead by ensuring these critical dates are firmly on your calendar.

December heralds the last opportunity to implement tax strategies that impact your 2025 filing. Taxpayers who’ve experienced income fluctuations, marital changes, new dependents, or property sales should prioritize a tax consultation with us. Our proactive planning helps navigate these changes effectively, ensuring you conclude the year with tax efficiency and confidence.

December 10 - Essential Tip Reporting

For employees earning tips, reporting is key. Ensure you report over $20 in tips received during November to your employer by December 10 using IRS Form 4070. This is vital for compliance with FICA taxes and income tax withholding. Unreported tips not withheld due to insufficient regular wages will appear in box 8 of your W-2, and you’ll reconcile this when filing your annual return.

If you were born before January 1, 1952, December 31 is your last day to avoid penalties by withdrawing from your Traditional IRA. Individuals who turned 73 in 2025 have until April 1, 2026, to make their first required distribution. Plan accordingly if your institution isn’t operating on December 31 to facilitate transactions in advance.

December 31 - Deadline for Deductible Expenses

Take advantage of your last chance to pay 2025 deductible expenses by December 31, extending post-deadline contributions to IRA, SEP, or Keogh plans. This proactive step helps capitalize on tax-deductible opportunities within the current fiscal year.

Consider completing year-end actions before December 31. Not all financial institutions operate on this date, which may impact your ability to execute last-minute financial tasks. Plan progress with time to spare, ensuring commitments aren’t hindered by institutional closures.

Weekend & Holiday Extensions

Note the automatic extension of deadlines falling on weekends or holidays to the next business day. This is essential for maintaining compliance with all due dates effortlessly.

Disaster Area Extensions

For regions designated as disaster areas, filing extensions may be available. Verify an area’s status through FEMA and IRS resources to address tailored filing extensions.
