🔍 Deadline for filing 1120/1120S returns electronically in SureFire

This guide explains the IRS filing deadlines for:

  • S Corporations (Form 1120S)
  • C Corporations (Form 1120)
  • Automatic extension requests (Form 7004)

⚠️ Before You Begin

Before you file electronically in SureFire, make sure you know:

  • Your entity type (S Corporation vs. C Corporation)
  • Your tax year end date (calendar year vs. fiscal year)
  • Whether your corporation dissolved or had its S election terminated

📊 Filing Deadlines (1120S and 1120)

S Corporation - Form 1120S

According to the IRS Instructions for Form 1120-S:

Generally, an S corporation must file Form 1120S by the 15th day of the 3rd month after the end of its tax year. For calendar year corporations, the due date is March 15, 2017. A corporation that has dissolved must generally file by the 15th day of the 3rd month after the date it dissolved.

 

If the S corporation election was terminated during the tax year and the corporation reverts to a C corporation, file Form 1120S for the S corporation's short year by the due date (including extensions) of the C corporation's short year return.

 

C Corporation - Form 1120

According to the IRS Instructions for Form 1120-C:

Starting with 2016 tax returns, all other C Corporations besides December 31 and June 30 year-ends (including those with other fiscal year-ends) will be due on the 15th of thefourth month after the year-end.

 

However, a cooperative with a fiscal tax year ending June 30 must file by the 15th day of the 3rd month after the end of its tax year. A cooperative with a short tax year ending anytime in June will be treated as if the short year ended on June 30, and must file by the 15th day of the 3rd month after the end of its tax year.

 

⏳ Extension of Time To File

Requesting an Automatic Extension

File Form 7004 to request an extension of time to file.

File Form 7004, Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns, to request an extension of time to file. Generally, the cooperative must file Form 7004 by the regular due date of the return.

 

❌ Note About Weekends and Holidays

If the due date falls on a Saturday, Sunday, or legal holiday, the corporation can file on the next day that is not a Saturday, Sunday, or legal holiday.
