Introduction
Forming a US LLC gives your business a formal legal structure and separates your personal assets from company debts. But the exact requirements shift depending on your formation state, ownership structure, business activity, and where you actually operate.
Many founders struggle with the same questions: Which state should I pick? Who can be my registered agent? What paperwork do I actually need? Do I need an EIN before or after filing?
This guide walks through eligibility, required documents, formation steps, realistic costs, and what changes if you're a non-US resident. We'll also cover what happens after your LLC gets approved, because approval is only the first step—banking, tax registrations, and ongoing state filings still follow.
Key Takeaways
- Formation succeeds only when you meet your state's rules on naming, registered agents, filing fees, and ongoing reports.
- State approval does not include business licenses, tax registrations, or banking access—you secure those separately.
- Non-US citizens can form an LLC, with extra EIN, identification, and banking steps to clear.
- Confirm current rules with your state authority and a qualified professional before filing anything.
What Is a US LLC, and Is It the Right Structure?
A limited liability company is a business entity created under state law. Members generally aren't personally responsible for the company's debts or lawsuits.
That protection has limits, though. It won't shield you from your own fraud, from mixing personal and business funds, or from a debt you personally guaranteed.
Core LLC features include:
- Single-member or multi-member ownership
- Member-managed or manager-managed structures
- Flexible ownership percentages and profit splits
- The option to elect different federal tax treatment
Why Founders Choose an LLC
An LLC gives you practical benefits most small and mid-size businesses need:
- Separates personal assets from business debts and lawsuits
- Offers operational flexibility that banks and customers recognize
- Allows pass-through taxation by default, so profits and losses flow to your personal return
Where LLCs Fall Short
LLCs aren't automatically the cheapest or simplest option in every case:
- Annual filings and franchise taxes vary widely by state
- Self-employment tax can apply to active members
- Bringing in outside investors is often more complicated than with a corporation
Quick comparison:
| Structure | Liability | Taxation | Best fit for |
|---|---|---|---|
| Sole proprietorship | None separate from owner | Owner reports directly | Solo, low-risk operations |
| Partnership | Personal liability for partners | Pass-through | Multi-owner ventures without formal structure |
| LLC | Owners generally shielded | Pass-through by default, elections available | Most small to mid-size businesses |
| Corporation | Owners generally protected | Separate corporate tax possible | Businesses seeking outside investment |
If you're planning to raise venture capital or issue stock options, a corporation might suit you better. For most founders running a services business, e-commerce store, or consulting practice, an LLC hits the right balance.
US LLC Formation Requirements: Essential Checklist
Before filing anything, work through these six requirements in order.
1. Choose the Right Formation State
Don't just pick the state with the cheapest fee. Consider:
- Where your business actually operates or has a physical presence
- Where the owners live
- Filing fees and recurring obligations
- Privacy rules (some states don't publicly list member names)
- Whether you'll need foreign qualification elsewhere anyway
2. Confirm Your LLC Name Meets State Rules
Your name typically needs:
- An approved designator, such as "LLC" or "Limited Liability Company"
- Distinguishability from existing registered entities in that state
- No restricted words (like "bank" or "insurance") without special authorization
Check both the state's entity database and USPTO trademark records before you fall in love with a name.
3. Appoint a Registered Agent
Your agent needs a physical address in the formation state and must be available during business hours to receive legal notices. You can appoint an individual or a commercial registered agent service.
That address does not have to match where you or your business actually operates.
4. Prepare Your Articles of Organization
Most states ask for:
- Legal LLC name
- Principal or mailing address
- Registered agent details
- Management structure (member- or manager-managed)
- Organizer information
- Effective date, if you want the filing delayed
5. Draft an Operating Agreement
Even in states that don't require one, put this in writing:
- Ownership percentages and capital contributions
- Voting rights and management powers
- Profit distribution rules
- Member exit and dispute procedures
- Dissolution terms
6. Research State-Specific Fees and Deadlines
Before you file, confirm for your chosen state:
- Exact filing fee and expedited-processing costs
- Publication requirements (New York, for example, requires newspaper publication)
- Annual-report or franchise-tax deadlines
Step-by-Step: How to Form a US LLC
Follow these eight steps in sequence:
- Decide if an LLC fits your business. Identify your members, management model, and intended activities first.
- Select your formation state. Confirm whether you'll also need foreign qualification elsewhere because of employees, offices, or inventory in another state.
- Search and reserve your name. Check the state database, restricted-word rules, domain availability, and trademark records.
- Appoint your registered agent. Gather the details your state's filing requires.
- Submit your Articles of Organization. Pay the fee and keep the approved formation certificate somewhere safe.
- Sign your operating agreement. Do this even if your state doesn't mandate one.
- Handle tax IDs, licences, and banking. Apply for an EIN where required, register for state and local taxes, obtain any industry-specific licences, and open a dedicated business bank account.
- Build a compliance calendar. Cover annual reports, agent renewals, tax deadlines, licence renewals, and foreign-qualification filings.
Watch for these common pitfalls:
- EIN timing: Don't apply for an EIN before the state approves the LLC. According to the IRS, state law creates the LLC, and federal tax classification follows it, not the reverse. Jumping the gun can delay processing.
- Tax classification default: A single-member LLC is typically disregarded for federal income tax, while a multi-member LLC is typically taxed as a partnership unless you elect otherwise. Confirm the default early so your filing obligations are clear.
Requirements for Non-US Citizens and Foreign-Owned LLCs
Your immigration status has nothing to do with your ability to own a US LLC. Australian and other non-US founders do not need a visa or US residency to be a member.
Documentation You'll Need
Non-US founders should be ready with:
- A passport or other government-issued identity document
- Foreign address details
- Ownership and beneficial-owner information
- Certified translations, if a bank or provider requests them
Getting Your EIN Without an SSN or ITIN
If your responsible party has no Social Security number or ITIN and isn't eligible for one, IRS Form SS-4 allows "foreign" or "N/A" on that field. The catch: the IRS's online EIN tool generally requires a US-based principal place of business, so most foreign applicants must apply by fax or mail instead, which takes longer.
Banking Challenges
Banks and payment providers will typically ask for:
- Formation documents and EIN confirmation
- Proof of address
- Identification for all beneficial owners
- Evidence of your business purpose
Expect this step to take longer than the LLC formation itself. Some providers won't open an account remotely at all, so factor that into your timeline.
Tax Reporting Doesn't Disappear Because You're Overseas
A wholly foreign-owned, single-member LLC with reportable related-party transactions, including contributions the owner makes to the LLC, generally must file Form 5472 attached to a pro forma Form 1120.
Skipping this isn't a minor slip: the IRS instructions describe a $25,000 penalty for failing to file. That applies even when the LLC is disregarded for regular income tax purposes.
Depending on your income, activities, and any applicable tax treaty, you may also face withholding obligations or state-tax questions that go beyond this single form. Get current advice from a US tax professional rather than assuming your situation matches a friend's.
Australian founders often run a US LLC alongside domestic operations or entities in other markets. VJM Global supports cross-border business structuring, accounting, and tax compliance advisory so US filings and home-country obligations are tracked together—including multi-jurisdiction setups that may also involve India.
That support works alongside your state filing authority and US legal counsel, not instead of them.
How Much Does It Cost, and What Happens After Formation?
There's no single "average" LLC cost. State fees and ongoing obligations vary too widely to average meaningfully, so split the numbers into formation costs and ongoing costs.
Formation-Related Costs
- State filing fee (varies significantly by state)
- Name reservation, if needed
- Registered-agent service fees
- Operating-agreement drafting
- Expedited-filing charges
- Publication costs, where a state requires it
Ongoing Costs
- Annual report or franchise tax
- Registered-agent renewal
- Business license renewals
- Tax filing and professional advisory fees
Here's how a few commonly chosen states compare:
| State | Initial state fee | Recurring obligation |
|---|---|---|
| Delaware | $110 Certificate of Formation | $400 annual tax by June 1; no annual report required |
| Wyoming | $100 filing fee | Annual report plus license tax of $60 or $0.0002 per dollar of in-state assets |
| Nevada | $425 combined (articles, initial list, business license) | Roughly $350 combined annually |
| California | $70 articles fee | $800 annual LLC tax, per the California Franchise Tax Board, plus a biennial $20 Statement of Information |
Notice how Nevada's headline $75 articles fee doesn't tell the whole story once you add the initial list and license charges. Always verify fees on the state's current schedule.
After Approval: Don't Stop at the Certificate
Getting your Articles of Organization approved isn't the finish line. From there:
- Open and maintain a dedicated business bank account
- Keep accurate books separate from personal finances
- Preserve your formation certificate and ownership records
- File annual reports and pay franchise taxes on schedule
- Renew licenses before they lapse
- Update your registered agent whenever details change
Watch for Foreign Qualification
If you formed in Wyoming for its low fees but run operations, hire employees, or lease office space in California, you'll likely need to register there too. Foreign qualification typically adds:
- An additional filing fee
- A registered agent in that second state
- Separate tax obligations
A cheap formation state doesn't cancel out the state where you actually do business.
Frequently Asked Questions
How much does it cost to form a US LLC?
Total cost depends entirely on your formation state and may include filing fees, registered-agent charges, annual reports, franchise taxes, licences, and professional services. Check your specific state's current fee schedule rather than relying on a general figure.
Can a non-US citizen register an LLC in the US?
Yes, non-US citizens can generally own or form a US LLC. You'll likely need a registered agent, identity documents, an EIN application, suitable banking documentation, and advice on both US and home-country tax obligations.
Do I need a US address to form an LLC?
You need a registered agent with a physical address in your formation state, but that's different from your own personal address. Banking requirements can add separate address or documentation demands.
Do all US LLCs need an EIN?
Not every single-member LLC without employees needs one for federal income tax purposes, but banking, state rules, or a foreign-owner reporting obligation often make an EIN necessary anyway.
Can I form an LLC in one state and operate in another?
Yes, but operating regularly in a second state often triggers foreign qualification there, meaning additional registration, fees, tax filings, and a registered agent in that state too.
What do I need to do after my LLC is approved?
Sign your operating agreement, apply for an EIN if needed, open a business bank account, register for applicable taxes, secure licences, and set up a calendar for annual reports and ongoing compliance.
