What
What the stamp is for.
A state forms a company when the certificate is accepted. The word on that page is the entity. People go looking for the letter S on it and feel a jolt when it is not there. The jolt is understandable. The letter S was never going to be on that page. The election is a federal filing, and it happens later, or it does not happen at all.
A filing fee paid to a state is the price of the certificate. Paying it does not tell the IRS how the company is taxed. An election is a separate federal form, and the acceptance letter is the only proof it landed. A registered agent has to agree to serve. A company is not allowed to be its own agent. The fee and the election are two different errands, and finishing one leaves the other untouched.
A drawer full of old menus is a pleasant kind of clutter. We can all appreciate a room that has kept its stuff. A certificate is the opposite of that clutter. It is one page, and the word on it is the whole point, which is why we ask to see the page and not a memory of having paid a fee.
