What Is an S Corporation?
An S Corporation is a C Corporation that elects “Subchapter S” status. All S Corporations begin their lives as C Corporations; Corporations elect to change their status to S Corporations.
The S Corporation Election is made by the filing IRS Form 2553 before the expiration of the 15th day of the third month of its tax year. You make your election by using the instructions to Form 2553 here, and using the election form 2553 which you can find here.
