Key Tax Deadlines for December 2025

This December, stay on top of your financial obligations with key tax reminders such as year-end planning, tip reporting, mandatory IRA withdrawals, and ensuring your deductible payments are completed for 2025.

December 1 - Initiate Year-End Tax Planning

December is the time to finalize actions impacting your 2025 tax outcomes. Those experiencing significant income fluctuations, changes in marital or dependent status, or property sales in 2025 should schedule a tax planning consultation promptly. Image 1

December 10 - Tip Reporting Obligations

Employees who received more than $20 in tips during November must report these to their employer by December 10 using IRS Form 4070. Employers will withhold the necessary FICA taxes and income tax withholding from your wages. Should regular wages not suffice to cover these withholdings, the uncollected amount will reflect in box 8 of your W-2 form, to be settled when filing your year-end tax return. Image 2

December 31 - Mandatory IRA Withdrawals Deadline

If you were born before January 1, 1952, today is the last opportunity to withdraw funds from your Traditional IRA to avoid penalties. For those born from January 1 through December 31, 1952, reaching age 73 this year, your first required distribution is in 2025, though it can be deferred until April 1, 2026. Ensure your financial institution is operational on December 31 to avoid timing issues.
