The documents you get after formation, and what each one is for

The documents a new US LLC has once it's formed, what each is for, who asks for them, and the certificates and apostilles a bank abroad wants, with fees.

Updated by the BaseAcross team. Reviewed by Saais Patel, compliance reviewer, against the sources named in the text.

The short answer

A new LLC has four documents that matter: the state's stamped articles, the IRS's EIN letter, the signed operating agreement and the registered agent's details. Banks, payment platforms and clients ask for those. A bank or tax office in your own country may also want a certificate of good standing, sometimes with an apostille, which you order when asked.

What every company has

The documents a new company has from day one
DocumentIssued byWhen you get itWho asks for it
Stamped Articles of Organization (Wyoming) or Certificate of Formation (Delaware)The state, on approvalThe same day it is filed in Wyoming; two to three weeks in DelawareBanks, payment processors, marketplaces and clients' supplier forms
File number and formation dateThe state, on the stamped documentWith the articlesBank forms and every later state filing
EIN confirmation letter (CP 575)The IRS, onceWhen the EIN is assignedBanks, processors, marketplaces and tax forms
Signed operating agreementDrafted by us, signed by the membersAt formationBanks, investors, and a court if it ever comes to that
Registered agent detailsThe agentAt formationThe yearly state filing, bank forms, and anyone serving legal papers
Receipt for the state feeThe stateAt filingYour accountant, and Form 5472, where paying the fee counts as a reportable transaction

A corporation has bylaws instead of an operating agreement, along with the incorporator's action, the first board consent, the stock ledger, the founders' share certificates or book entries, and any 83(b) elections.

  • A certificate of good standing confirms the company exists and is up to date with its filings. Banks abroad and some platforms want one dated within the last few months. Delaware's long form lists every filing, which a bank doing deeper checks may ask for.
  • A certified copy of the filed articles, from the state, is for when a stamped copy isn't enough.
  • An apostille is added by the Secretary of State to a certified document so authorities in other Hague Convention countries accept it. Countries outside the Convention ask for legalisation through their consulate instead. An IRS letter is a federal document, so its apostille comes from the US Department of State, not the state. You can order one from us.
  • A certificate of incumbency, signed by the company's manager or an officer, lists who holds which position. Some banks abroad ask for one.

If you lose one

Ask the state for a certified copy of the articles, or print a fresh good-standing certificate. Ask the IRS by phone for a 147C letter in place of the CP 575, because the IRS issues the CP 575 only once; CP 575 or 147C explains how. A lost operating agreement can be re-signed by the members on the same terms, noting the original date.

Keeping them in one place

Each document goes into your documents when it arrives, with the certificate and the EIN letter at the top, so the current versions are in one place when a bank asks. Keep any paper originals too, and scan the CP 575 the day it arrives.

What a bank actually checks

That the company's legal name is spelled the same everywhere, the EIN matches the IRS letter, the addresses agree, and the owner's name on the operating agreement matches the passport. When a bank declines for a reason other than your country, a mismatch between two documents is a common cause, so read everything through once before you apply. A US bank account for a non-resident's LLC lists what each bank asks for.
