LLC formation documents: the complete checklist

Small Business · 4 min read · Updated 2026-07-14

Filing your Articles of Organization with the state creates the LLC. Everything after that determines whether it protects you or leaves you exposed.

Quick answer:

Filing your Articles of Organization with the state creates the LLC. Everything after that determines whether it protects you or leaves you exposed.

State filing documents

Articles of Organization (or Certificate of Formation, depending on state) — the state-stamped filing that creates the LLC.

Certificate of Good Standing — proves the LLC is current with the state. Banks and clients ask for this regularly.

Registered Agent designation — required in every state; can be the owner or a paid service.

Federal & tax

EIN (Employer Identification Number) — apply free at irs.gov/ein. Required for a business bank account, hiring, and most tax elections.

S-Corp election (Form 2553) if you elected S-Corp taxation. Deadline is 2 months and 15 days after formation for the first year.

State tax registrations — sales tax, employer withholding, unemployment insurance if you have employees.

Operating documents

Operating Agreement — even single-member LLCs need one. Courts use it to determine whether the LLC actually operates separately from you (piercing the corporate veil).

Membership certificates — proof of ownership percentages. Critical for future partners, sales, or estate planning.

Banking & licensing

Business bank account opening documents. Business licenses and permits specific to your city and industry.

Do not commingle personal and business funds. This is the #1 reason courts pierce LLC protection.

The bottom line

Every LLC owner should have Articles, EIN letter, Operating Agreement, and Good Standing certificate accessible on demand. VaultGuardian's Business Vault keeps them together and shareable with your accountant.
