Essential Tax Deadlines for Businesses and Employers: 2024 Q4 Tax Calendar

Ken Botwinick, CPA | 10/01/2024

As the fourth quarter of 2024 approaches, businesses and employers must be aware of important tax deadlines to avoid penalties and stay compliant. Below are key tax dates that may impact your business, but keep in mind that this list isn’t exhaustive. Additional deadlines may apply depending on your situation, so be sure to consult with us to ensure you’re meeting all filing requirements and staying on top of any tax-related obligations.

Note: Tax-filing and payment deadlines may be extended for those in federally declared disaster areas. Contact us for more information if this applies to you.

October 1, 2024

  • SIMPLE IRA Plan Deadline
    If you’re looking to establish a SIMPLE IRA plan for your business, this is the last day to do so provided neither you nor any predecessor employer has maintained a SIMPLE IRA in the past. New employers that come into existence after October 1 can set up a SIMPLE IRA plan as soon as administratively possible after the business begins operations.

October 15, 2024

  • C Corporation Income Tax Return (Form 1120)
    If your C corporation operates on a calendar year and you filed for an automatic six-month extension, this is the deadline to file your 2023 income tax return. Be sure to pay any outstanding tax, interest, and penalties.
  • Employer-Sponsored Retirement Plan Contributions
    Calendar-year C corporations should also make any 2023 contributions to qualified employer-sponsored retirement plans by this date.

October 31, 2024

  • Third Quarter 2024 Income Tax Withholding and FICA Reporting
    Employers must report third-quarter income tax withholding and FICA taxes (Form 941) and make any payments due by this deadline. See the exception below if you qualify for a November 12 deadline.

November 12, 2024

  • Third Quarter 2024 Income Tax Withholding and FICA (Form 941)
    If you deposited all associated taxes for the third quarter on time and in full, you qualify for an extended deadline to report your income tax withholding and FICA taxes.

December 16, 2024

  • Fourth Installment of 2024 Estimated Income Taxes for C Corporations
    Calendar-year C corporations must make the fourth installment of their 2024 estimated income tax payment by this date to avoid penalties.
