how do you go about becoming a s inc.?

Answer 1

Your question is a little unclear.

To become a corporation, you have to file articles of incorporation with your state. Being a corporate entity is considered a right, not a privilege. Usually you merely have to have your ducks in a row and the articles are accepted without question.

If you're asking about becoming a an "S" corporation, you have to be a "C" corp first, then file your taxes each year with the status of an "S" corp. You are always presumed to be a "C" corp until you file your 1120 each year.

It's much better to own an LLC. You should consider that instead.

Answer 2

You have to file paperwork with the IRS within 45 days of the close of your calendar year. Are you aware of the finer details of becoming an S corp? If you aren't, you may want to have a sit down discussion about this with a CPA.
