Key October 2025 Tax Deadlines

As October ushers in cooler weather, it also marks crucial tax deadlines for individuals. For those who filed a 6-month extension, October 15 is the last day to submit your 2024 Form 1040 and pay any taxes owed. Missing this deadline could result in penalties, so timely filing is essential for tax compliance.

October 10 - Report Tips to Your Employer

Employees who receive tips should remember that if you earned more than $20 in tips during September, you must report them to your employer using IRS Form 4070 by October 10. This enables the appropriate withholding of FICA taxes and income tax from your regular wages. Should your regular wages be insufficient to cover these withholdings, your employer will note the shortfall in box 8 of your W-2, requiring you to pay the uncollected amount upon filing your year's tax return.
