What Are the Penalties for Late Filing of Form 1120?
Corporations are required to file Form 1120 annually to report their income, deductions, and other essential information to the IRS. If a corporation fails to file Form 1120 by the due date, it may face penalties. The IRS charges penalties based on the amount of unpaid taxes and how late the filing is.
1. Failure to File Penalty
The most common penalty for late filing is the “Failure to File” penalty. This penalty is calculated as a percentage of the unpaid tax liability. As of 2025, the IRS imposes the following penalties:
- 5% per month: The penalty for failing to file Form 1120 on time is 5% of the unpaid taxes for each month or partial month the return is late, up to a maximum of 25% of the unpaid tax.
- After 60 days: If the return is filed more than 60 days late, the minimum penalty is the lesser of $435 or 100% of the unpaid tax.
For example, if a corporation owes $10,000 in taxes and files its return 3 months late, the penalty would be $1,500 (5% of $10,000 per month for 3 months).
2. Interest on Unpaid Taxes
In addition to the failure to file penalties, the IRS charges interest on any unpaid taxes. The interest rate is determined by the IRS and is based on the federal short-term rate plus 3%. Interest accrues from the due date of the tax return until the taxes are paid in full.
What Happens if I Can’t File on Time?
If you are unable to file Form 1120 on time, it’s important to take action quickly. The IRS allows corporations to request an extension of time to file the return. This extension will give your business additional time to file the tax return without facing the late filing penalty. However, it is important to note that an extension only applies to the filing deadline, not the payment deadline.
Can I Request an Extension for Filing Form 1120?
Yes, businesses can request an automatic 6-month extension to file Form 1120. To do this, the corporation must submit Form 7004, “Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns,” by the original due date of the return (typically the 15th day of the 3rd month after the end of the corporation’s fiscal year). This form must be filed even if the corporation does not owe any taxes.
Important Considerations:
- The extension grants additional time to file the return, but it does not extend the time to pay any taxes owed. The corporation must still estimate and pay any taxes due by the original deadline to avoid penalties for failure to pay.
- If the extension is approved, the new filing deadline will be six months later, typically the 15th day of the 9th month after the corporation’s fiscal year ends.

How to Avoid Late Filing Penalties for Form 1120
While extensions can help businesses avoid late filing penalties, proactive tax planning and timely filings are the best ways to avoid penalties altogether. Here are a few strategies to minimize the risk of late filing penalties:
1. Set a Calendar Reminder for Tax Filing Deadlines
One of the simplest ways to avoid penalties is to mark your corporation’s tax deadlines on a calendar and set reminders ahead of time. This will help you keep track of the original filing date and ensure that you have enough time to gather the necessary documentation for your tax return.
2. Make Estimated Tax Payments
If your corporation expects to owe taxes, it’s important to make estimated tax payments throughout the year. The IRS requires quarterly estimated tax payments for corporations that expect to owe more than $500 in taxes. These payments can help reduce the amount owed when you file your return and avoid underpayment penalties.
3. Work with a Tax Professional
Working with a tax professional can ensure that your corporation’s taxes are filed on time and that you take advantage of all available deductions and credits. A tax consultant can also help you stay on top of deadlines and make timely decisions regarding extensions if needed.
How PEAK BCS Can Help: At PEAK BCS, we specialize in corporate tax filings, ensuring that your business meets all tax deadlines and stays in compliance with IRS regulations. We help you plan your taxes throughout the year, file your returns accurately, and request extensions when necessary, all while minimizing your tax liabilities.
What if I Miss the Extension Deadline?
If you miss the extension filing deadline, you will face the same penalties as if you had missed the original filing deadline. However, it’s never too late to take action. If you miss the extension deadline, you should file Form 1120 as soon as possible and pay any taxes owed to minimize penalties and interest.
The IRS may offer penalty relief for businesses with reasonable cause for missing deadlines, so it’s important to communicate with them and provide supporting documentation if applicable. In some cases, you may be able to have the penalties reduced or waived.
