This guide is written for Australian founders, foreign investors, and businesses weighing up a US LLC. It's a starting point, not a substitute for state-specific legal advice or a proper look at your cross-border tax position — both of which need separate attention. We'll cover what the certificate actually does, what information the states ask for, how filing works in practice, and what still needs sorting out once approval lands in your inbox.
Key Takeaways
- A Certificate of Formation is a state-level filing, not an IRS document or federal registration
- Some states call the same document Articles of Organization or Certificate of Organization
- State approval creates the LLC but doesn't provide an EIN, bank account, licences, or tax registrations
- Australians can generally own a US LLC, but banking, tax, and reporting questions require separate review
What Is an LLC Certificate of Formation?
A Certificate of Formation is the document you submit to your chosen US state to establish an LLC as a distinct legal entity under that state's law. Once the state accepts it, the LLC generally gains the standing to enter contracts, own assets, open bank accounts, and conduct business under its own name, subject to whatever federal and state requirements apply to your specific activity.
Terminology isn't consistent across the country. Delaware and Texas both use the term Certificate of Formation. California, New York, and Wyoming file the same type of document but call it Articles of Organization instead. Before you file anything, check what your chosen state actually calls its form. Don't assume one state's naming convention applies everywhere.
Certificate of Formation vs Related Documents
People often confuse the formation certificate with other documents that serve entirely different purposes:
- Operating Agreement — the internal document covering ownership splits, voting rights, management authority, profit distribution, and member responsibilities
- EIN — the federal tax identification number the IRS issues after formation, where required
- Certificate of Good Standing — proof that an already-formed LLC remains current on its state obligations, not the document that created it
- Certificate of Authority — a separate filing that lets an existing LLC operate legally in a state other than where it was formed
The Certificate of Formation usually doesn't state each member's ownership percentage. If you need to prove who owns what, that evidence sits in your Operating Agreement and your membership records, not on the state's approval document.
Why the Certificate Matters and Where It Is Used
An LLC needs to be formally created before it can reliably present itself as a real entity to banks, customers, suppliers, and government agencies. Without an approved certificate, you're operating a business that legally doesn't exist yet.
In practice, you'll be asked to produce your approved certificate when:
- Opening a business bank account
- Applying for an EIN with the IRS
- Signing contracts with suppliers or clients
- Obtaining industry licences or permits
- Onboarding with payment providers or marketplaces
- Demonstrating legitimacy to potential partners or investors
Formation alone doesn't guarantee liability protection holds up under scrutiny. Owners still need to keep separate finances, maintain proper records, and avoid blending the LLC's affairs with their personal ones. Courts have pierced the liability shield of plenty of LLCs that were treated as personal wallets rather than genuine businesses.
For Australian founders specifically, forming a US LLC does not automatically:
- Register a company in Australia or determine how the entity is taxed here
- Grant any right to live or work in the United States
- Remove possible US, Australian, state, or local reporting obligations
Your filing applies to the state where you formed the LLC. If your business conducts sufficient activity in another state, you may also need to register there — a process typically called foreign qualification. There's no single national test for this.
State approaches differ:
- California looks at repeated, successive intrastate transactions
- Wyoming excludes activities like simply holding a bank account or selling through independent contractors
- Texas assesses the nature and extent of your operations without a fixed statutory definition
Check the destination state's own rules before assuming you're covered.
How Do You Get a Certificate of Formation?
Filing starts with choosing your formation state and reviewing that state's current requirements, terminology, fees, and filing methods, because they differ.
Step-by-Step Filing Process
- Choose the state based on your commercial, operational, and tax objectives, not purely because a particular state has low fees or favourable tax treatment
- Search the state's business name database to confirm availability, check the required LLC designator, and note any restricted words or reservation options
- Appoint an eligible registered agent with a physical address in the formation state, who takes responsibility for receiving legal and official correspondence
- Gather the required information, typically including your proposed legal name, principal address, purpose statement, management structure, organiser details, registered-agent information, and effective date
- Submit the current official form through the state's Secretary of State (or equivalent) system, pay the applicable fee, and keep proof of submission and payment
- Monitor the filing, respond promptly to any rejection or correction request, and download the approved certificate once it's issued
Fees and timing vary considerably by state:
| State | Formation fee | Expedited option |
|---|---|---|
| Delaware | $110 | Next-day (+$50) or same-day (+$100) |
| Wyoming | $100 | Not offered |
| Texas | $300 | Standard (+$50), next-day (+$500), same-day (+$750) |
Delaware's current fee schedule confirms the $110 formation fee, with expedited processing available for an additional charge. Wyoming, by contrast, offers no rush option at all. Mailed filings can take up to 15 business days.
Some Australian founders prefer support coordinating the setup process alongside related compliance work. VJM Global can help with that coordination, though state-specific legal and tax advice should always come from appropriately qualified professionals in that jurisdiction.
What Happens After the Certificate Is Approved?
Certificate approval unlocks the next setup steps. Check the issued certificate immediately for spelling errors, incorrect addresses, wrong management structure, or an inaccurate effective date. Mistakes here are easier to fix now than months later.
Immediate Post-Approval Tasks
- Prepare an Operating Agreement covering ownership, contributions, voting, authority, profit allocation, dispute handling, and exit procedures, even if your state does not require filing
- Apply for an EIN where required or commercially useful; IRS Form SS-4 instructions cover foreign applicants without an SSN or ITIN, including fax and mail options
- Open a dedicated business bank account and keep separate accounting records to preserve the LLC–owner distinction
- Review compliance obligations across federal, state, local, and Australian requirements, including tax registrations, sales tax where relevant, and cross-border reporting
One area that trips people up: beneficial ownership reporting. FinCEN's current guidance confirms that entities created in the United States, and their beneficial owners, are exempt from federal Corporate Transparency Act reporting, even if an owner lives outside the US.
That exemption does not affect your bank's customer due-diligence checks, which typically still require identifying anyone owning 25% or more of the entity.
A few things formation alone will never hand you:
- Business licences or permits specific to your industry
- Insurance coverage
- Payment-provider or marketplace approval
- Payroll registrations if you plan to hire
Build a compliance calendar for annual or biennial reports, franchise or state taxes, registered-agent renewals, and any foreign qualification filings you'll need down the track.
Your individual tax treatment as an Australian owner depends on facts specific to you: ownership structure, income source, where management happens, where your customers sit, and where activities actually occur. Generic guidance will not cover your situation, so get advice tailored to it.
Key Factors, Common Issues, and When It May Not Be Appropriate
Before you file, weigh up these factors:
- State-specific naming, registered-agent, disclosure, signature, and fee requirements
- Single-state operations versus registration triggers in other states
- Ownership structure, member residency, and intended tax classification
- Cross-border tax, reporting, currency, and recordkeeping considerations for Australian owners
- Industry licences or regulated-activity requirements that formation alone won't satisfy
Common mistakes worth avoiding:
- Using an outdated or unofficial state form
- Filing before checking name availability
- Appointing an ineligible registered agent
- Entering inconsistent addresses across the form
- Assuming approval automatically handles your EIN and tax registrations
A US LLC isn't always the right structure. It may not fit if:
- Your business primarily operates in Australia
- You need a different investment vehicle
- You expect corporate tax treatment
- Banking and cross-border compliance complexity outweighs the benefit
Get professional advice before you file — not after.
Conclusion
A Certificate of Formation is the state filing that creates a US LLC and gives it a genuine separate legal existence. Getting there successfully depends on accurate, state-specific information, an eligible registered agent, correct submission, and critically, what you do after the state approves your filing.
For Australian founders, formation, tax, banking, and ongoing compliance are separate questions that need separate answers. When your facts get complicated, qualified advice is what keeps a solid plan from turning into an expensive mistake.
VJM Global supports Australian businesses with US entity formation and the tax and compliance work that follows approval.
Frequently Asked Questions
How do I file a Certificate of Formation for an LLC?
Choose your state, confirm the name is available, and appoint an eligible registered agent. Complete the official state form, pay the fee, and submit through the state's filing system—you'll receive the approved certificate when processing is complete.
What is an LLC Certificate of Formation?
It's the state filing that legally creates an LLC as a separate entity. Some states call the same document Articles of Organization or Certificate of Organization instead.
Can a foreigner open a US LLC?
Yes. Non-US residents can own or form a US LLC. Registered agent, EIN, banking, and tax or reporting requirements still need to be handled separately.
What document proves you own an LLC?
The Certificate of Formation proves the LLC exists, but it doesn't usually show ownership percentages. Your Operating Agreement, membership ledger, or ownership schedule is what actually evidences who owns what.
