Key Tax Deadlines for October 2025

The arrival of October signals a cooling in weather and marks important tax deadlines that should not be overlooked. For those who benefitted from a 6-month filing extension, October 15 is the final opportunity to file your 2024 Form 1040 and settle any outstanding tax liabilities. Ignorance of this due date could result in penalties.

October 10 - Tip Reporting for Employees

Employees who receive tips must report any earnings exceeding $20 from September to their employer using IRS Form 4070 by October 10. Your employer is responsible for withholding FICA taxes and income tax on these tips from your paycheck. Should your regular pay be inadequate to meet these withholdings, any uncollected amounts will be reflected in box 8 of your W-2. These unmet obligations will have to be paid with your tax return filing.

October 15 - Foreign Financial Interests

For taxpayers granted an automatic 6-month filing extension, October 15 is the cutoff date for submitting Form FinCEN 114, reporting foreign financial accounts to the Treasury Department. It is crucial to adhere to these deadlines to avoid penalties.

October 15 - General Individual Deadlines

Those who applied for an extension to file their 2024 income tax return must complete Form 1040 and handle any related tax, interest, and penalties by this date. Compliance ensures a smooth tax process and circumvents any additional levies.
