Key October 2025 Tax Deadlines You Must Not Miss

October ushers in cooler temperatures along with crucial tax deadlines. If you've taken a 6-month extension, ensure that October 15 is prominently marked on your calendar—it's the final date to submit your 2024 Form 1040 and resolve any outstanding tax liabilities to avoid penalties.

October 10 - Tip Reporting Deadline

For employees earning more than $20 in tips during September, it's essential to report these earnings to your employer using IRS Form 4070 by October 10. Employers are obligated to withhold FICA and income taxes on these tips from your regular wages. Should your wages fall short in covering these taxes, the uncollected amount will be indicated in box 8 of your year's W-2. You will be responsible for paying the shortfall upon filing your annual return.

October 15 - Foreign Financial Assets

For those receiving an automatic 6-month extension, this is also the due date to submit Form FinCEN 114 to report any foreign financial accounts for 2024 to the Department of the Treasury.

October 15 - Individual Tax Filers

Individuals who have requested a 6-month extension need to ensure they file Form 1040 and pay any taxes, along with interest and penalties accumulated, by this date.
