Federal tax ID (EIN)

Banks require an EIN to open a business account, and you need one to hire or to file most tax returns. We prepare the application and obtain the number for you once the company is filed.

Registered agent

Every LLC must name a registered agent with a physical street address in the state, available during business hours. Pick whichever suits you; there is no wrong answer.

The address must be a physical street address in CT.

What happens once you pay

  • Filed with your state within one business day
  • A specialist reads your order first. If anything looks wrong, we email you before filing, not after.
  • Rejected by the agency? We fix it and file again at no charge.
  • If we cannot get it filed at all, you get everything back, including the government fee.
  • Track it in your account with your email address. There is no password to invent.

State processing after that is the agency's queue, which runs from same day to a few weeks depending on where you are filing. We do not control it, so we do not promise a date for it.

Payment is handled by Stripe. Nothing is filed until payment clears, and government fees are refunded in full if we cannot file.

Filed in a day. One flat price. Nothing you didn't ask for.

  • Filed within one business day

    One tier, one speed, every order. There is no rush fee here because there is no slow lane to buy your way out of.

  • A specialist reads every filing

    Prepared and checked by someone who files these all day. If your name or address will not clear the state, you hear from us before it goes in.

  • Registered agent at $99, only if you want one

    The lowest published rate of the five services we compare, sitting beside a free option to name yourself. Most people never need to buy it.

  • One price, and nothing starts on its own

    $100 to form, $50 flat for every filing after. The only thing that can renew is a registered agent you chose, at the price you chose it for. No tiers, no trial that turns into a charge.
