Key Tax Deadlines for December 2025: Essential Reminders

As 2025 draws to a close, it's crucial to keep track of important tax dates to optimize your tax situation. This year-end checklist will guide you through essential tax activities including strategic planning, tip reporting, mandatory IRA withdrawals, and final deductible payments. These tasks help ensure you're in compliance and maximize potential benefits.

December 1 - Year-End Tax Strategy
  • Take stock of this year’s financial changes, such as significant income fluctuation, marital status shifts, or property sales, and plan your taxes accordingly. Schedule a consultation to tailor a tax strategy that aligns with your circumstances and anticipates 2026 obligations.

  • If you’re in a tip-based occupation and received over $20 in tips during November, file IRS Form 4070 by this date. Ensure proper FICA tax and income tax withholding by notifying your employer promptly to avoid discrepancies in your annual tax filing.
December 31 - IRA Withdrawal Obligation Image 1
  • For those born before January 1, 1952, this is the deadline to take mandatory distributions from your Traditional IRA to evade penalties. If you turn 73 this year, consider whether to take your first distribution or delay until April 1, 2026. Ensure arrangements are in order if financial institutions close before year-end.

  • Settle any deductible expenses for the 2025 tax year by this date, excluding contributions to IRA, SEP, or Keogh plans, which have a later cutoff. To avoid last-minute hassles, check with your financial institution on operational hours.
Weekend and Holiday Considerations
  • If deadlines fall on weekends or public holidays, the due date shifts to the following business day, preventing penalties from impeding your financial planning.
Disaster Area Extensions
  • Be aware that IRS-designated disaster areas receive extended deadlines. For updates, check FEMA’s disaster declarations and IRS tax relief information.

Managed effectively, these steps may provide a smoother transition into the next fiscal year, aligned with your personal financial goals and obligations. At Tangible Accounting, PLLC, we’re here to assist you through these tax complexities.
