S Corp & C Corp

One of these is an entity. The other is a box you tick at the IRS
The lead

A corporation is formed by filing with a state. What happens next is a separate decision made with a different agency: an S Corporation is a tax election status that a corporation — or an LLC — adopts by filing Form 2553 with the IRS. A C Corporation is not a filing either: it is simply what a corporation is taxed as by default, before anyone elects anything.

Business partners discussing a corporate formation file in a U.S. office

The distinction is not academic for the reader who arrives here. Choosing the wrong entity type on the initial filings can lead to rejection at the IRS — and for an international founder the second plane is closed altogether: a nonresident alien cannot be an S corporation shareholder.

Start here

Three questions, in the order they get answered.

1

The direct answer, and the entity decision that comes with it.

2

Governance, default taxation and what each one is actually good at.

3

Converting an LLC, and where the Form 2553 election fits.

Errors of plane

Three founders who confused the entity with its tax treatment
The filing that does not exist

There is no S Corporation formation document. You form a corporation or an LLC with a state, and then elect the tax status with the IRS by filing Form 2553.

The wrong entity, filed

Choosing the wrong entity type on the initial filings can lead to immediate rejection by the IRS, and unwinding it later is a conversion, not a correction.

The closed door

For federal tax purposes a nonresident alien cannot be an S corporation shareholder. The plane exists; for this founder it is simply not available.

The two planes

One is filed with a state. The other is elected with the IRS

A corporation or an LLC, brought into existence by a filing with a state. It sets governance: a corporation runs on shareholders, board and officers; an LLC follows an operating agreement and can be member- or manager-managed.

Filed with a state

Corporations default to C-Corp taxation: the company pays corporate income tax and distributions can be taxed again at shareholder level. LLCs default to pass-through treatment.

Automatic, unelected

An S Corporation is a tax election status adopted by filing Form 2553. It allows pass-through taxation with different treatment of self-employment tax. It is a choice made after the entity exists, with a tax adviser.

Elected with the IRS

The direct answer, the entity decision and the mistakes the IRS rejects.

Governance, default taxation and what each structure is actually good at.

What a conversion involves, and where the tax election fits into it.

What Form 2553 changes, and what it does not.

Proving it exists

What a corporation is by default

Notary Public Center

The certificate, the certified copy, and the version that travels

Whatever entity is chosen, what a bank, an investor or a foreign registry reviews is paper: a Certificate of Good Standing, a certified copy of the charter, and often an authenticated version for use abroad. Notary Public Center prepares and certifies them.
