A Wyoming LLC can get an EIN (the company’s tax ID) while the owner still has no personal US tax ID. People collapse those two numbers into one errand and then stall: they delay formation waiting for an ITIN they do not need yet, or they try to open a personal bank account with only the company EIN. The useful sequence is — LLC first, ITIN when a person needs a US TIN.
ITIN = Individual Taxpayer Identification Number (Form W-7), for a person who is not eligible for an SSN. EIN = Employer Identification Number, for the entity. Full definitions: ITIN number explained and ITIN vs EIN. Formation: Wyoming LLC package. Managed W-7: US ITIN Assistance.

Important: IRS procedures, bank KYC, and credit underwriting change. This is educational orientation — not tax, legal, immigration, or credit advice. An ITIN is not work authorization and not immigration status. Do not treat examples as a guarantee of approval. Wyoming formation does not zero-out US tax for US persons, and an ITIN does not create immigration status.
The Mix-Up That Wastes Months
Non-US founders usually need the company to exist before a bank, payment platform, or counterparty will talk. The IRS can issue an EIN to that company without the owner holding an ITIN. Personal tax filings, some KYC files, and some “SSN or ITIN” form fields are a later problem.
The expensive mistake is treating W-7 as a formation prerequisite. IRS ITIN timing after a complete filing is typically 2–4 months and is IRS-controlled. Parking the LLC for that whole window is usually unnecessary.
The other expensive mistake is assuming the EIN unlocks every personal US account. Many personal products still ask for a human TIN. That is when the ITIN path in how to get an ITIN actually starts.
Need a CAA-Managed ITIN?
If the missing piece is the personal W-7 — not the LLC — use the remote CAA path. Pricing is on the ITIN service page, not here.
What You Actually Get From Each ID
| ID | Belongs to | Typical job |
|---|---|---|
| EIN | The Wyoming LLC | Entity tax file, many business bank applications, 5472/BOI context |
| ITIN | A specific person | Personal US tax return / 1040-NR style filings, some personal KYC |
| SSN | A person eligible for Social Security | Do not apply for an ITIN if you can get an SSN |
ITINs do not authorize work, do not grant immigration status, and do not replace an SSN for people who are eligible for one. They also do not replace FinCEN BOI for the company — that is a separate filing (FinCEN assistance).
Recommended Sequence
- Decide the entity is actually needed. A Wyoming LLC is a US company with US filing gravity. If you only needed a local LatAm invoice entity, read the corporate-structures comparison first — do not form Wyoming by habit.
- Form the LLC and obtain the EIN. How to open a Wyoming LLC from abroad and the done-for-you Wyoming LLC package.
- Open the business account path with the EIN + formation docs when a bank or fintech will accept that package. See Wyoming LLC bank account.
- Start the ITIN only when a person needs a US TIN — personal return, a KYC file that rejects EIN-only, a spouse/dependent on a US filing, or a treaty/ITIN workflow. Process: how to get an ITIN.
- Keep company reporting on the company calendar — BOI, registered agent, annual report — independent of W-7 timing.
Canadians stacking this with a tax-exit plan should also read ITIN from Canada and Escape Canada. The LLC does not, by itself, end Canadian tax residency.
When You Can Wait on the ITIN
- The only immediate need is forming the company and getting an EIN
- The bank or processor accepted the EIN + operating agreement + passport KYC for a business account
- You have no US-source personal filing due this season
- No platform has rejected you specifically for a missing personal TIN
Waiting is not the same as skipping forever. If a 1040-NR, a personal brokerage, or a card issuer is in the next 90 days, start W-7 now — CAA packaging is faster on your side, but the IRS clock is still months.
Banking vs Tax vs BOI
Business banking cares about the company’s existence, EIN, owners, and source of funds. An ITIN may be requested for a controlling person; it is not always the blocker. Personal banking more often wants a human TIN. Context: US bank account with an ITIN and US banking for non-residents.
Tax is where the ITIN earns its keep: a person who must file and cannot get an SSN. Entity returns and information returns still hang off the EIN. See tax returns for non-residents and Wyoming LLC taxes for foreigners.
BOI / FinCEN is beneficial-ownership reporting for the company. Do not treat a W-7 receipt as BOI compliance. Different form, different agency rhythm — FinCEN filing assistance.

Documents That Usually Matter
- LLC: articles, operating agreement, registered-agent record, EIN letter
- ITIN (W-7): valid passport as the usual standalone identity document, plus the exception-category support for why you need the number (bank letter, return, LLC facts). CAA vs mail: process guide and what a CAA is.
- Bank KYC: whatever that institution lists — often passport + proof of address + formation pack. An ITIN notice (CP565) helps when they asked for a personal TIN.
Do not mail an original passport to the IRS if a CAA path is available. That is the operational reason MLL offers remote CAA assistance.
Failure Modes
- Waiting on W-7 to form the LLC — usually backwards.
- Using the EIN as a fake SSN/ITIN on personal forms — rejects and mess.
- Applying for an ITIN when you are eligible for an SSN — wrong product.
- Duplicate first-time W-7 while an ITIN already exists — reconstruct or renew instead.
- Assuming the LLC + ITIN ends home-country tax — US persons still file; Canadians still need a real exit.
- Skipping BOI because “we got an ITIN” — unrelated.
Who This Stack Is Not For
- US persons who already have an SSN and just wanted a state-tax talking point
- People who need work authorization or a visa — this stack does not provide either
- Founders who actually need a local LatAm operating company, not a US LLC
- Anyone shopping a “second passport via Wyoming” story — that is not how this works
Worked example (non-US founder)
You live in Mexico. Clients pay in USD. You form a Wyoming LLC and receive an EIN. A business account application asks for formation docs and the EIN — not an ITIN. You operate for a season. In April a US withholding form or a personal brokerage KYC asks for SSN or ITIN. That is the W-7 moment, not month zero.
If instead a personal US bank or a 1040-NR is already on the calendar, start the CAA package in parallel with formation so the IRS clock runs while the company exists. Parallel is fine. Blocking formation on W-7 is usually not.
After the CP565 arrives
Keep the assignment notice. Match the legal name to the passport and to every later form. Give the number to the bank or preparer that actually asked for a personal TIN. If the notice never shows, reconstruct — do not guess digits (how to verify an ITIN).
Then stay on the company calendar: registered agent, Wyoming annual report, BOI if it applies. The ITIN does not file those for you.
Need a CAA-Managed ITIN?
MLL packages Form W-7 on a remote Certifying Acceptance Agent path so the standard process does not require mailing your original passport to the IRS. Current pricing is on the service page.
Frequently Asked Questions
Do I need an ITIN before I can form a Wyoming LLC?
Usually no. Formation and EIN are company steps. Start W-7 when a person needs a US TIN.
Can I open a US bank account with only the EIN?
Sometimes for a business account, subject to that bank’s KYC. Personal accounts more often want a personal TIN. No ITIN guarantees approval.
Does the IRS charge a fee for the ITIN?
The IRS does not charge a separate government fee to process Form W-7. Fees you pay are for preparation/CAA help — see US ITIN Assistance for MLL’s managed path (do not copy a stale number from an old article).
How long does the ITIN take once I file?
Typically 2–4 months after a complete filing, IRS volume dependent. MLL controls packaging speed, not issuance.
Should Canadians form Wyoming to escape CRA?
No. A US LLC is not a Canadian residency exit. Use the ITIN/LLC stack for US infrastructure, and a real exit plan if that is the goal — Escape Canada.
ITIN vs EIN — which do I buy first?
Entity first in most non-US founder stacks. Deep split: ITIN vs EIN.
