To open a bank account for your Wyoming LLC, you need an Employer Identification Number from the IRS, your filed Articles of Organization, a written operating agreement, and government-issued photo ID for every person who will be authorized to sign on the account. Multi-member LLCs should also bring a banking resolution naming the authorized signers. With those documents in hand, you can apply at a traditional bank branch or through an online-first business banking platform, and approval typically takes two to five business days.
Documents to Bring to the Bank
Employer Identification Number
Every bank will ask for your LLC’s EIN before opening the account. This nine-digit number functions as a Social Security number for the business. You can get one for free through the IRS online application tool, which issues the number at the end of the session.1Internal Revenue Service. Get an Employer Identification Number Applicants outside the United States can apply by phone, fax, or mail using Form SS-4.2Internal Revenue Service. Instructions for Form SS-4 – Application for Employer Identification Number Print the EIN confirmation letter and bring it with you. Pick one application channel and stick with it, because applying through more than one method can produce duplicate EINs and create problems with the IRS later.
Articles of Organization
Your Articles of Organization are the formation document filed with the Wyoming Secretary of State, and they prove the LLC legally exists.3Wyoming Secretary of State. Wyoming Secretary of State Limited Liability Company Articles of Organization Banks use them to confirm the LLC’s exact legal name, its filing ID, and its formation date. The name on your bank account has to match the name on these documents character for character. Even a small discrepancy between “LLC” and “L.L.C.” can hold up the application.
Some banks will ask for a Certificate of Good Standing instead of, or in addition to, a plain copy of the Articles. A Certificate of Good Standing from the Wyoming Secretary of State costs $20, and a certified copy of a filed document costs $10.4Wyoming Secretary of State.

Operating Agreement
Most banks want to see a written operating agreement before they’ll open the account. It tells them who has authority to manage money, sign checks, and authorize wire transfers. Wyoming law itself does not require the operating agreement to be in writing: the statute allows it to be “oral, in a record, implied, or in any combination thereof.”5Wyoming Legislature. Wyoming Statutes Title 17-29-102 – Definitions A bank, though, has no way to verify an oral agreement. Showing up without a written one that names the authorized signers will usually stall or kill the application.
Banking Resolution for Multi-Member LLCs
If your LLC has more than one member, the bank may ask for a banking resolution. This is a document adopted by the members that names which individuals can open accounts, sign checks, initiate wire transfers, and conduct other financial transactions on behalf of the LLC. It typically includes the business name, the bank’s name, the authorized individuals, the scope of their authority, and the date of approval. Some banks hand you their own template. Others accept a freeform version, which may need to be notarized.
Photo Identification for Every Signer
Every person who will be authorized on the account must present valid government-issued photo identification, such as a driver’s license or passport. Banks verify these identities under federal anti-money laundering rules, which require collecting each signer’s name, date of birth, address, and identification number at account opening.6Office of the Law Revision Counsel. 31 USC 5318 – Compliance, Exemptions, and Summons Authority
What the Bank Verifies About the Owners
Federal law under the USA PATRIOT Act requires every financial institution to run a customer identification program before opening any account.7Financial Crimes Enforcement Network. USA PATRIOT Act – Section 326 Verification of Identification For an LLC, that means the bank verifies both the entity and the people behind it.
Under FinCEN’s Customer Due Diligence rule, the bank must identify and verify the beneficial owners of the LLC. A beneficial owner is anyone who directly or indirectly owns 25 percent or more of the LLC’s equity, plus at least one individual with significant management responsibility.8Financial Crimes Enforcement Network. CDD Rule FAQs Expect the bank to ask each beneficial owner for their name, date of birth, address, and Social Security number or other identification number. Under a February 2026 FinCEN order, banks collect this information when the account is first opened and then again only if something calls the original information into question.9Financial Crimes Enforcement Network. FinCEN Issues Exceptive Relief to Streamline Customer Due Diligence Requirements
One thing you can cross off: FinCEN’s separate Beneficial Ownership Information reporting requirement. As of March 2025, all entities formed in the United States are exempt from filing BOI reports with FinCEN, and the rule now applies only to foreign entities registered to do business in a U.S. state.10Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting The bank’s own CDD process at account opening is a separate obligation and still applies to every LLC.
Extra Steps if the LLC Has Foreign Owners
Members without a Social Security number face additional requirements. A foreign passport is the primary identification document most banks will accept. Many major banks also accept an Individual Taxpayer Identification Number in place of an SSN for the tax-reporting portion of the application, though the IRS itself says an ITIN is not designed to serve as identification outside the federal tax system.11Internal Revenue Service. Individual Taxpayer Identification Number Whether a specific bank will accept it depends on that institution’s internal policies. Call ahead.
If the LLC is treated as a foreign entity for tax purposes, the bank will likely require a completed Form W-8BEN-E before any payments are made through the account. This form establishes the entity’s foreign status and determines withholding obligations. It must be provided before the first payment, and if your circumstances change, you have 30 days to submit an updated version.12Internal Revenue Service. Instructions for Form W-8BEN-E
Banks also require a physical street address for the business, not just the registered agent’s address. The registered agent exists only to receive legal notices and doesn’t establish operational presence. A P.O. Box won’t satisfy the requirement either. Some banks will accept a virtual office address if it corresponds to an actual physical location rather than a mail forwarding service, but policies vary. For founders running a Wyoming LLC remotely from overseas, the physical address requirement is often the hardest part.
In Person, Online, and FDIC Coverage
You have two main paths. A traditional bank branch typically requires an in-person visit where the authorized signer physically signs a signature card, which becomes the bank’s reference for verifying future checks and wire transfers. If no branch is convenient, some national banks let you start the application online and finish it by mailing notarized documents. Online-first banking platforms handle the entire process digitally: you upload scanned formation documents, complete digital identity verification, and sign electronically.
Approval typically takes two to five business days either way. Once approved, the bank issues a routing number and account number, and you make an initial deposit to activate the account.
Before choosing a bank, check its FDIC coverage. The standard federal deposit insurance limit is $250,000 per depositor, per insured bank, for each account ownership category.13FDIC. Deposit Insurance at a Glance The LLC’s deposits are insured separately from your personal accounts at the same bank, but all of the LLC’s accounts at a single bank are aggregated under one $250,000 cap. If the business will hold more than that, consider spreading deposits across multiple insured institutions.
Business checking accounts commonly carry monthly service fees that are waived if you maintain a minimum daily balance, and many include only a set number of free deposits or transactions per month before per-item charges start. Ask for the fee schedule upfront and compare it against your expected transaction volume before committing.
Why the Separate Account Matters Legally
The point of an LLC is that your personal assets stay off-limits if the business gets sued or can’t pay its debts. Courts can strip that protection through a process called piercing the corporate veil, and the fastest way to invite it is mixing personal and business money. Depositing business revenue into a personal checking account, paying personal bills with the business debit card, or loaning yourself money without a written promissory note all count as commingling. A judge looking at those facts can conclude the LLC was never really separate from you and hold you personally liable for business obligations.
A dedicated business bank account creates a clean paper trail showing the LLC operates on its own. Every deposit, withdrawal, and transfer becomes part of a record that demonstrates the business is a distinct legal entity. That record matters most when someone challenges your liability protection, which is exactly when you can’t afford messy finances.
Keeping the Account Open After You’ve Opened It
Wyoming requires every LLC to file an annual report with the Secretary of State. The report is due on the first day of the anniversary month of the LLC’s formation. If your LLC was formed on August 15, the annual report is due each year by August 1.14Wyoming Secretary of State. Annual Report Online Filing The minimum fee is $60 for LLCs. Missing the deadline puts the LLC into delinquent status and can eventually lead to administrative dissolution. A dissolved LLC can’t legally transact business, and a bank that discovers the entity is no longer in good standing may freeze or close the account.
Tell the bank whenever the LLC’s structure changes. Adding or removing a member, changing the business address, replacing the registered agent, or amending the operating agreement to shift signing authority all call for an update. Banks that find a mismatch between their records and the Secretary of State’s filings during routine audits can freeze the account until the discrepancy is resolved.
