October 10: Reporting Tips to Employers

If you’re an employee who earned more than $20 in tips in September, you must report these to your employer using IRS Form 4070 no later than October 10. Your employer is obligated to withhold FICA and income taxes on these tips from your regular pay. Should your earnings be insufficient to cover these liabilities, the uncollected amounts will be noted in box 8 of your W-2. You'll need to address these upon filing your annual tax return.

October 15: Foreign Financial Interests

For taxpayers with foreign financial accounts, October 15 also signifies the due date for filing Form FinCEN 114, provided you opted for an automatic 6-month extension.

Final Reminder for Individual Tax Filers

The same date, October 15, applies to all individuals who extended their income tax filing. Ensure your Form 1040 is submitted alongside any due taxes, interest, or penalties.

Weekends & Holidays

Should a filing deadline fall on a weekend or federal holiday, it automatically shifts to the next business day.

Extensions for Disaster Areas

If you reside in an area recently declared a disaster zone, filing deadlines may be extended. Check the following resources for updates on eligible disaster areas and related tax relief: Visit FEMA and IRS for details.
