Your company’s legal identity and its federal tax treatment answer different questions. Paul Diaz explains Form 2553, the S corporation election, and Form 1120-S, the tax return, in 30 seconds.
A Company Name Is Not A Tax Plan.
The label on your business and the tax treatment on your return are different parts of the picture. Know which question you are answering before choosing the form.
The Election. The Return. The Question Behind Both.
Form 2553 is the election for an eligible entity. Form 1120-S is the return for a year covered by an S corporation election. Start with that distinction, then bring your own facts into the conversation.

Questions Worth Asking
What Is The Difference Between Form 2553 And Form 1120-S?
An eligible corporation or other eligible entity uses Form 2553 to elect S corporation status. Form 1120-S reports income, deductions and other tax items for a year covered by that election. The election and the annual return serve different purposes.
Does Filing Form 1120-S Make My Company An S Corporation?
Form 1120-S is the tax return, not the election form. The IRS identifies Form 2553 as the form for an eligible entity to make the S corporation election. Eligibility, timing and your company’s actual election history need their own review.
