Key Tax Deadlines for October 2025

As the chilly winds of October approach, it's crucial to stay on top of significant tax deadlines. For those who took advantage of a six-month extension for their 2024 tax returns, October 15 marks the final opportunity to file Form 1040 and settle any remaining tax obligations. Missing this deadline could lead to penalties, so it's critical to act promptly.

October 10 - Report Tips to Employers

For tipped employees who earned over $20 in tips during September, it's mandatory to report these earnings to your employer by October 10 via IRS Form 4070. Your employer will then deduct FICA and income taxes from your regular wages. If your wages aren't enough to cover these withholdings, the shortfall will be documented in box 8 of your W-2 form. You’ll need to pay this uncollected amount along with your annual tax return.
