How Long Does It Take to Form a US LLC? (2026 State Timelines)

Most founders want their company live fast. The good news: forming a US LLC is quick — often just a few business days — though the full setup (EIN, banking) takes a little longer.

State formation timelines

• Wyoming, New Mexico, Colorado — often 1–3 business days.
• Delaware — fast, with expedited options.
• Some larger states are slower; expedited filing is available in many.

EIN timeline for non-residents

Without an SSN, the EIN is obtained by fax/mail, which can take longer than the instant online route. Plan for a few extra days to a few weeks depending on IRS load.

Bank account & full setup

Once the LLC and EIN are ready, opening a US bank account is usually quick (days). End-to-end, many non-residents are fully operational within 1–3 weeks.

How to speed it up

• Pick a fast state (see our best state guide).
• Have your passport and details ready upfront.
• Use expedited filing if you are in a hurry.

FAQ
