April 2025 Business Tax Deadlines: Key Dates & Essential Filing Tips

Business Tax Deadlines

Keeping up with tax deadlines is essential for businesses and individuals to stay compliant and avoid penalties. April is a key month for everyone with several necessary tax filing and payment due dates. Through this guide, we will walk you through the key deadlines, business tax filing ideas, and what you need to do to keep your business on track.

Important Tax Deadlines for April 2025

April 15 – Corporate Tax Filings & Payments
  • C-Corporations (Form 1120): If your business operates as a C-corporation, you need to file your 2024 income tax return by this date first. If you need extra time, file Form 7004 for an auto 6 month extension. But, you need to remember that an extension only applies to the filing deadline—not to payments. You will need to estimate what you owe and make a payment to avoid late penalties.
  • Estimated Tax Payments: If your C-corporation follows a calendar year, your first estimated tax payment for 2025 is due on this date.
April 15 – Payroll & Withholding Taxes
  • Social Security, Medicare, and Withheld Income Tax: If your business follows the monthly deposit schedule, the taxes withheld from the March payroll must be deposited.
  • Non-Payroll Withholding Taxes: Businesses with non-payroll payments requiring withholding (such as retirement distributions or backup withholding) must deposit the withheld taxes for March by this date.
April 15 – Fiduciary Tax Returns
  • Estates and Trusts (Form 1041): Fiduciaries managing estates and trusts must file their 2024 income tax return. If you need additional time, an extension could be filed to push the deadline further.
April 30 – Payroll & Unemployment Tax Deadlines

Quarterly Payroll Tax Filing (Form 941)

  • Employers must file Form 941 to report payroll taxes for the first quarter of 2025. If you still owe taxes for the quarter, they must be deposited under the accuracy of deposit rules.
  • If your payroll tax liability is less than $2,500, you can submit the full payment along with the form.
  • If you made all required deposits on time, you can file Form 941 until May 12.
    Federal
Unemployment Tax (FUTA) Deposits
  • If your business owes more than $500 in Federal Unemployment Tax (FUTA) for the first quarter, you must deposit the payment by this date.

Adjustments for Weekends & Holidays

If a tax deadline falls on a Saturday, Sunday, or legal holiday, the IRS automatically extends it to the next business day. Make sure and double-check adjusted due dates if your deadline lands on a weekend or holiday.

Tax Extensions for Disaster Affected Areas

The IRS often grants filing extensions to businesses located in federally declared disaster areas. If your business is in an affected region, check the IRS website for updated deadlines and special relief measures. Visit the Internal Revenue Service website today for detailed information regarding all disaster relief guidance issued by the IRS and all the filing extension dates.

Conclusion

April is a busy month for tax filings, and missing deadlines can result in penalties. Mark these dates on your calendar and ensure that all necessary forms and payments are submitted on time. If you need additional time, file for extensions where applicable and stay proactive to avoid last-minute stress.
