Key Tax Deadlines for December 2025

As the year wraps up, it’s crucial to keep abreast of pivotal tax deadlines to optimize your tax planning and financial outcomes. This month’s tax reminders encompass year-end strategy, tip declarations, IRA withdrawals, and concluding deductible expenditures for 2025.

December 1 - Initiate Year-End Tax Strategies

December marks the time to finalize key tax-related decisions that could influence your 2025 returns. Individuals who experienced significant financial changes, such as notable shifts in income, variations in marital or dependent status, or real estate transactions during 2025, should promptly schedule a tax strategy consultation.

December 10 - Deadline for Reporting Tips

Employees earning tips must report any tip income over $20 received in November to their employer by December 10 using IRS Form 4070. Employers are then obliged to withhold FICA and income taxes from your regular earnings. Should your regular earnings be insufficient to cover these withholdings, the employer will reflect the shortfall in box 8 of your W-2, which you'll need to reconcile when filing your annual return.

December 31 - Final Date for Required IRA Withdrawals

This is the deadline to execute mandatory withdrawals from Traditional IRA accounts if you were born before January 1, 1952. Individuals celebrating their 73rd birthday in 2025 (birthdated January 1, 1952, through December 31, 1952) may defer the withdrawal till April 1, 2026. Ensure you arrange any necessary transactions in advance if your financial institution closes before December 31.

December 31 - Deadline for Deductible Expense Payments

Conclude all deductible expense payments for 2025 by this date, excluding contributions to IRA, SEP, or Keogh plans, which may be settled post-December 31, 2025.

December 31 - Important Year-End Considerations

For actions requiring more than a day or institutions closed on December 31, undertake necessary steps ahead of the deadline to avoid complications.
