Hello Everyone!

This is my first post on the forum and I have a question.

I recently incorporated my small business in October 2016 and I'm in the process of filing my first tax return. I was not aware of electing S-Corp status within 75 days of incorporation, so I planned on filing my 2553 with my 1120S.

Back on the 15th I submitted a 7004 automatic extension however it was rejected because I hadn't done the S-Corp election.

My question is, is it possible to file a 7004 as a C-Corp, thereby extending the deadline of the 1120 till September, but instead of filling the 1120, I file an 1120S with the appropriate 2553?

Thanks in advance!
