File Your 1120 Corporate Tax Extension Online and Avoid Costly Penalties

When is the Deadline to File Corporate Tax Form 1120?

The deadline to file corporate tax return Form 1120 is on or before the 15th of the fourth month following the end of the tax year.

If the C-Corp operates on a calendar tax year, the deadline to file Form 1120 for the 2024 tax year is
April 15, 2025.

If your business doesn’t follow the calendar year basis, find your correct due date here.

Thus, if you are unable to file form 1120, you can
E-File 7004 and get an extension for up to 6 months.

How to File a 1120 Extension?

C-Corporations that need more time to prepare and file their Form 1120 can request additional time by filing Form 7004.

C-Corporations that file Form 7004 on or before the original filing deadline will get an automatic extension of up to 6 months of additional time from the IRS to file Form 1120. This extension is automatic, so you are not required to provide any explanations for requesting additional time.

C-Corporations with a tax year ending on June 30 can request a 7-month extension (Unless they request an extension for Form 1120-POL).

What are the penalties associated with
Form 1120?

There are two types of penalties if Form 1120 is filed late or if there is a late payment
of taxes.

• Late Filing Penalty: If a corporation fails to file its 1120 return by the due date (including extensions), it will face a penalty of 5% of the unpaid tax for each month or part of a month the return is late. The penalty can accumulate up to a maximum of 25% of the unpaid tax.
  

  If the return is over 60 days late, the minimum penalty is either the tax due or $510.

• Late Payment Penalty: If the corporation does not pay the tax due by the original deadline, a penalty of 0.5% per month on the unpaid tax will be applied. This penalty can also accumulate up to a maximum of 25% of the unpaid tax.
  

  To avoid penalties, request a 6 month extension with Form 7004.
