Disregarded LLC A yes leaves the state filing where it was
A yes leaves the state certificate where the state already has it, with no reason to amend that filing.

Two papers people keep folding into one
The certificate is the state's record that the company exists. The income-tax classification is a federal description of where the profit is reported. A vendor form borrows words from the second paper, and owners hear a threat to the first. The statute is quiet. The scare is the speed of someone else's form.
A yes, when it is the honest description, leaves the certificate alone. You do not file an amendment because a marketplace learned a new adjective. You do not pay a formation service to "restore" a company that was never closed. If someone has already quoted that work, ask them which agency would receive the filing and what fact changed. If the only fact is the vendor's question, the filing has no fact under it.
When people amend anyway
The invoice usually arrives with a story. The story says the company was out of status, or that a yes somehow dissolved it, or that a registered agent must be replaced because a form was confusing. None of those sentences follows from a checkbox. A registered agent changes when you change agents. A certificate changes when the company's own facts change. A vendor's confusion is not one of those facts.
Bring the quote if you already have one. The useful reply is often a short note you can send back, saying the company remains in good standing and the tax classification is whatever the last return shows. We will help you write that note in plain words. Your name stays on the note. Ours does not go on it as a representative.
The company is older than their screen
That is the turn. The fear was disappearance. The paper on the right, the return, is older than the form on the left. Read them in that order and the box gets smaller. It is still worth answering. It is no longer worth a rescue.
A quote is not a filing
A formation service can send a quote the same evening the vendor question arrives. The quote often names an amendment, a revival, or a new registered agent, and it rarely names the agency that would receive anything. Ask that question before you pay. If the only change in the world is a checkbox on a marketplace, no agency is waiting for a filing. The company you already have is the company the state already has. Paying to restore it spends money on a disappearance that did not happen.
Keep the quote in the same folder as their form. On the call we read the quote the way we read their sentence, looking for the fact it claims has changed. A fact is a new owner, a new name, a move to another state, or a real election you already filed. A mood is not a fact. Worry is not a fact. The word on their screen is not a fact about the certificate. If the quote cannot point at a fact, the useful work is a short note back to the vendor, in your name, saying the company stands and the return shows the classification.
People who already paid that invoice still have a company. The payment did not create a second status, and it did not erase the return you signed. Bring both the receipt and the return. The reading then separates what the state actually changed, if anything, from what a salesperson described. Most of the time the state changed nothing, and the remaining work is the vendor's file, not another purchase. Ask which agency would receive the filing before any invoice is paid.
Ask before you amend anything
If someone quoted a fix, paste the sentence they used.
