What Is an LLC? Complete Guide for 2026

What Is an LLC? Complete Guide for 2026

 Min Read

We've helped founders from over 60 countries form US LLCs without a single one setting foot in the US. Every single one of them started with the same question.

What exactly is an LLC?

This guide gives you the complete answer — definition, structure, tax treatment, costs, and the parts that generic explanations get wrong or skip entirely.

In this guide, you'll learn:

  • Exactly what an LLC is and how it's legally structured
  • How LLCs are taxed — including the rules that apply specifically to foreign owners
  • How an LLC compares to a sole proprietorship, partnership, and corporation
  • What it costs to form and maintain one, state by state
  • Whether non-US residents can own a US LLC (they can)
The short answer: An LLC — Limited Liability Company — is a legal business structure registered at the state level that separates your personal assets from your business debts and legal obligations. If your business is sued or can't pay its bills, your home, personal savings, and personal bank accounts are generally protected.

Everything else flows from that core concept.

What Does LLC Stand For?

LLC stands for Limited Liability Company.

  • Limited — your personal financial exposure has a ceiling. Business creditors can't normally come after your personal assets.
  • Liability — refers to legal and financial obligations the business takes on.
  • Company — it's a registered legal entity, distinct from its owners.

The LLC was created in Wyoming in 1977, modeled partly on the German GmbH structure. It was designed to give small business owners the liability protection of a corporation without the rigid governance requirements. Today all 50 US states recognize the LLC, and it has become the most common business structure for small and mid-sized companies in the country.

One persistent misconception: people often say "limited liability corporation." That's incorrect. An LLC is a company, not a corporation. The two are legally distinct structures with different rules — a distinction that matters when you're deciding which one to form.

How an LLC Is Structured

When you form an LLC, you file a formation document — usually called the Articles of Organization or Certificate of Formation, depending on the state — with the state's filing agency (typically the Secretary of State) and pay a state filing fee. That filing creates the LLC as a legal entity — separate from you.

Members: Who Owns the LLC

LLC owners are called members — not shareholders. That distinction is intentional. Shareholders exist in corporations; members exist in LLCs. The two structures carry different legal rights and governance rules.

An LLC can have:

  • One member (a Single-Member LLC, or SMLLC)
  • Multiple members, with no legal cap on the number
  • Members who are individuals, other LLCs, corporations, or trusts
  • Non-US residents as members — citizenship and residency are not required

Ownership stakes are expressed as percentage interests, not shares of stock.

Member-Managed vs. Manager-Managed

Every LLC is either member-managed or manager-managed. In a member-managed LLC, the owners run the business directly. In a manager-managed LLC, a designated manager — who may or may not be an owner — has authority to act on behalf of the company.

Member-Managed Manager-Managed
Who controls day-to-day decisions All members (or majority) Designated manager
Best for Active founders, solo operators Passive investors, larger LLCs
Common for non-residents Most common (for solo founders and e-commerce) Common only for passive investors

Most single-member LLCs are member-managed.

The Operating Agreement

The Operating Agreement is your LLC's internal governing document. It defines ownership percentages, profit distribution, voting rights, what happens when a member exits, and how the LLC gets dissolved. States like New York, California, and Delaware legally require LLCs to have one; most other states (including Wyoming) don't mandate it by law, but strongly recommend it.

A poorly drafted Operating Agreement — or having none at all — can undermine the liability protection the LLC is supposed to provide. Courts have pierced the corporate veil (meaning personal assets become fair game) when an LLC operated without clear rules and the owner couldn't demonstrate it was a real, separate entity.

The Four Benefits That Actually Matter

1. Limited Liability (the Corporate Veil)

The liability shield is the LLC's defining feature. When properly maintained, it means business debts, lawsuits, and legal judgments against the LLC cannot reach your personal assets.

The key phrase is when properly maintained. Courts can pierce the corporate veil — meaning they'll hold you personally liable — in specific circumstances most articles don't mention:

  • Commingling funds: Using your personal bank account for business transactions (or vice versa) signals the LLC isn't a real separate entity.
  • Undercapitalization: Forming an LLC with essentially no assets to cover foreseeable liabilities can void the protection.
  • Personal guarantees: If you personally guarantee a business loan, you're personally liable for it regardless of the LLC.
  • Fraud: No legal structure protects against intentional fraud.

The fix for most of these is simple: open a dedicated business bank account, keep clean records, and don't use the LLC as a personal ATM.

2. Pass-Through Taxation

A standard LLC doesn't pay federal income tax at the entity level. Profits and losses pass through directly to the members, who report them on their personal returns. This eliminates the double taxation that C-Corporations face — where the company pays corporate tax on its profits, and then shareholders pay income tax again when those profits are distributed as dividends.

For a single-member LLC, the IRS treats the entity as a disregarded entity — it's legally separate from you, but tax-wise it doesn't exist as its own taxpayer. You report the LLC's income on Schedule C of your personal Form 1040. Foreign-owned single-member LLCs must file an informational return with the IRS (Form 5472 and a pro forma Form 1120), which is typically due on April 15th every year.

For multi-member LLCs, the default treatment is as a partnership: the LLC files an informational Form 1065, and each member receives a Schedule K-1 showing their share of profits and losses.

3. Tax Flexibility

An LLC can elect to be taxed as a C-Corporation by filing IRS Form 8832 — useful in specific situations where retaining profits at the corporate rate makes sense.

It can also elect S-Corporation tax treatment by filing IRS Form 2553, which lets US owners split income between salary (subject to self-employment tax) and distributions (not subject to SE tax), potentially saving thousands per year. However, S-Corp status requires all members to be US citizens or US residents for tax purposes (which includes permanent residents as well as individuals living in the US who pass the IRS Substantial Presence Test). Foreign-owned LLCs without US tax residency are not eligible.

Note: S-Corp is not a separate entity structure like LLC or C-Corp. It is just a "Tax Status".

4. No Residency Requirement

This one matters for international founders: the US has no citizenship or residency requirement for forming or owning an LLC. You can be based anywhere in the world and own 100% of a US LLC, legally and with full rights. This makes the US LLC the default structure for non-US entrepreneurs who want access to US banking, US payment processors, and US business credibility.

Three Real Disadvantages

Not Compatible With Venture Capital

If you plan to raise institutional venture capital from US-based funds, a Delaware C-Corporation is the expected structure. Most VC funds won't invest in an LLC due to the tax complications it creates for their limited partners. If raising VC funding is on your roadmap, factor this in before you commit to an LLC.

Self-Employment Tax

US citizens and residents who are active members of an LLC pay self-employment tax (15.3% on the first $184,500 of net earnings in 2026) on LLC profits. This covers Social Security and Medicare. There's no equivalent corporate contribution to split it — it all comes out of your pocket. Electing S-Corp taxation is how many US-based owners reduce this burden, but it involves additional compliance and payroll.

Non-US residents are generally not subject to US self-employment tax on foreign-source income, but the specifics depend on your country of residence, the nature of your income, and whether the US has a tax treaty with your country.

Annual Compliance Costs

An LLC requires ongoing maintenance: annual state reports, annual fees, and potentially federal tax filings. These aren't optional. Miss them and your LLC loses its "good standing" status, which affects your ability to open bank accounts, sign contracts, and maintain the liability protection you paid for. Failure to file franchise tax or annual reports can lead to penalties and LLC dissolution (depending on the state).

How LLCs Are Taxed: The Complete Picture

Tax treatment is where LLCs are genuinely flexible — and where the rules for foreign owners diverge sharply from what most guides describe.

For US-Resident Owners

LLC Type Default Tax Treatment Return Filed
Single-member LLC Disregarded entity — income on owner’s Form 1040 (Schedule C) None at entity level
Multi-member LLC Partnership — income allocated to each member Form 1065 + K-1s to each member
LLC electing C-Corp Corporate taxation, double tax on distributions Form 1120
LLC electing S-Corp Pass-through, but salary + distributions split Form 1120-S + W-2s

For Non-US Resident Owners

This is what most "what is an LLC" articles skip entirely.

A foreign-owned single-member LLC is still a disregarded entity for tax purposes. But because the foreign owner isn't filing a standard US resident tax return (Form 1040), the IRS enforces strict corporate reporting rules to maintain visibility. The IRS therefore requires:

  • Form 5472: An information return disclosing the foreign owner's identity and any transactions between the owner and the LLC (capital contributions, distributions, loans). Required annually.
  • Form 1120 (pro-forma): A corporate-format return filed alongside the Form 5472 — even if no tax is owed.

The penalty for failing to file Form 5472: $25,000 per year. Per LLC. This is not widely known, and it catches a significant number of non-resident owners off-guard in their second or third year of operation.

Whether you owe actual US income tax depends on whether your LLC has Effectively Connected Income (ECI) — income generated from US-based business activity. If your LLC earns money from US clients for services physically performed while in the US (or if you have employees or dependent agents operating within the US), that is generally ECI and is taxable. If you're operating entirely from your home country and just using a US LLC for banking access to sell digital goods or services, it generally is not.

Your home country's tax treaty with the US may also affect your obligations.

LLC vs. Other Business Structures

Feature Sole Proprietorship LLC S-Corp C-Corp
Personal liability protection None Yes Yes Yes
Pass-through taxation Yes Yes (default) Yes No (double tax)
Available to non-US residents N/A Yes No Yes
VC fundraising No Rarely No Yes (standard)
Annual compliance Minimal Moderate Higher Highest
Formal governance required No No Payroll required (meetings only if underlying entity is a Corporation) Yes (board, minutes)

Choose an LLC if: You're a freelancer, consultant, e-commerce seller, agency owner, or small business founder who wants liability protection and banking access without corporation-level overhead.

Choose a C-Corp if: You're building a venture-backed startup and intend to raise institutional money. Delaware is the standard jurisdiction.

Types of LLCs

Single-Member LLC (SMLLC)

A single-member LLC has one owner and is the most common structure for solopreneurs and freelancers. For US owners, the IRS treats it as a disregarded entity — income flows straight to your personal tax return. or non-US owners, it triggers the Form 5472 and pro-forma Form 1120 annual filing requirements. Either way, it carries simpler governance and fewer compliance requirements than a multi-member LLC.

Multi-Member LLC

A multi-member LLC has two or more owners and is taxed as a partnership by default. It requires a thorough Operating Agreement to define ownership rights, profit sharing, and exit terms — dissolving or restructuring a multi-member LLC without one is expensive and contentious.

Series LLC

A Series LLC is available in Wyoming, Delaware, Texas, and a handful of other states. It creates one "master" LLC with multiple legally separate "series" underneath it — each with its own assets, members, and liabilities — without the cost and complexity of forming separate LLCs. Real estate investors commonly use this structure to isolate individual properties under one umbrella entity.

Professional LLC (PLLC)

A Professional LLC is required in many states for licensed professionals — doctors, lawyers, architects, and accountants. It functions identically to a standard LLC regarding general business debts, but it does not shield the owner from personal liability for their own professional malpractice. It can only be owned by licensed practitioners in the relevant profession. For most international entrepreneurs using a US LLC for e-commerce or service businesses, this type isn't relevant.

How to Form a US LLC

This is an overview. For the full step-by-step process — including state-specific instructions and non-resident-specific steps — read our dedicated guide: How to Register a US Company from Abroad as a Non-Resident.

Step 1: Choose Your State

Non-US residents are not restricted to any particular state. The most common choices:

State Filing Fee Annual Fee Privacy Best For
Wyoming $100 $60/year High — no public ownership records Most non-residents
Delaware $160 (24h Expedited) $300/year High VC-track startups
New Mexico $50 $0 High Budget-conscious founders
Florida $125 $138.75/year None US-based operations in FL

Fees accurate as of June 2026. Verify at each state’s Secretary of State website before filing.

(Fees accurate as of June 2026. Verify at each state's Secretary of State website before filing.)

Wyoming's combination of low annual cost, privacy protections, and an established LLC statute makes it the default recommendation for most non-resident founders. For a deeper comparison: Best US States for Foreigners to Form an LLC.

Step 2: Appoint a Registered Agent

Every US LLC must have a registered agent — a person or company with a physical US address in the formation state, available during business hours to receive legal and government correspondence. Non-US residents can't serve as their own registered agent, so you'll need to hire a service. StartFleet includes registered agent service in all plans by default.

Step 3: File Articles of Organization

File with your state's filing agency. For Wyoming, you'll file your Articles of Organization online at wyobiz.wyo.gov. You'll need your LLC name, your registered agent's details, and your principal office address (can be your registered agent's address).

Step 4: Get an EIN

Your Employer Identification Number (EIN) is your LLC's federal tax ID — required to open a US business bank account and file US tax returns or Form 5472/Pro Forma 1120 (for Non-US residents). US residents apply online at irs.gov/ein in minutes. Non-residents cannot use the online tool and must apply by:

  • Fax: Complete IRS Form SS-4 and fax it to the IRS. You must choose the correct fax number based on where you are physically located when sending the fax:
    • If you are OUTSIDE the United States: Fax your form to +1 (304) 707-9471.
    • If you are INSIDE the United States (or using a U.S.-based e-fax service): Fax your form to ​(855) 215-1627​.
    • If your business has a physical U.S. office/residence in the 50 states: Fax your form to ​(855) 641-6935​.
  • Mail: Mail Form SS-4 to the IRS. Allow 8–12 weeks.

Step 5: Open a US Business Bank Account

With your LLC documents and EIN in hand, you can open a US business bank account. For non-residents, the most accessible options are Mercury (online-first, no monthly fee), Wise Business (multi-currency, excellent for international payments), and Relay. All three work with foreign-owned LLCs.

For a full breakdown of your options: US Bank Accounts for Non-Residents.

Step 6: Draft an Operating Agreement

Only a few U.S. states legally mandate an Operating Agreement, but as a non-U.S. founder, you must treat it as an absolute necessity regardless of where you incorporate.

This internal document outlines your business’s ownership structure and management rules. Even if you are the sole owner of a Single-Member LLC, you need a signed Operating Agreement to:

  • Open U.S. Bank Accounts: Sometimes banks require it to verify ultimate beneficial ownership.
  • Protect Your Liability Shield: It proves your LLC is a separate legal entity, which is the primary way to protect your personal assets from business liabilities.
  • Override State Defaults: It prevents your LLC from automatically defaulting to generic state laws that aren't optimized for foreign owners.
Note: You do not file the Operating Agreement with the state. Simply sign it and keep it safely stored with your company’s internal records.

What Does an LLC Cost?

StartFleet all-in pricing (Wyoming, most popular):

  • Freelancer — $449 total (includes $100 state fee, registered agent, EIN, US mailing address)
  • Startup — $599 total (adds Express EIN and Stripe consultation; most popular)
  • Business — $1,099 total (adds ITIN, Form 5472, and Form 1120 filing)

(Prices accurate as of June 2026. Current pricing at https://startfleet.io/pricing.)

Can Non-US Residents Form a US LLC?

Yes — and there is no asterisk. US LLC formation has no citizenship, residency, or visa requirement. A founder in Lagos, Dubai, or Bangalore can form and own 100% of a US LLC without visiting America.

Requirement Required?
US citizenship No
US residency or visa No
US Social Security Number No
US physical address No (registered agent covers this)
Physical presence in the US No
A registered agent with a US address Yes

The LLC structure is what gives international founders access to the US business infrastructure — Mercury or Wise bank accounts, Stripe and PayPal merchant accounts, and the credibility that comes with a registered US legal entity.

What is different for non-residents: the EIN application process (cannot apply online; must use phone, fax, or mail),the Form 5472 annual filing requirement (for single-member LLCs), and the fact that S-Corp taxation is not available. These are manageable with the right setup from day one.

LLC Compliance: What You're Required to Do Each Year

Forming an LLC is not a one-time event. These are the ongoing obligations:

State Annual Report

Most states require an annual report and fee to keep your LLC in good standing. Let those lapse and your LLC eventually gets administratively dissolved.

State Annual Fee Report Due
Wyoming $60 1st day of anniversary month
Delaware $300 June 1
New Mexico $0 Not required
Florida $138.75 May 1

Federal Tax Filing

Your federal filing obligations depend on your ownership structure and residency:

  • US-resident single-member LLCs report income on Schedule C of their personal Form 1040. No separate LLC return is required.
  • Multi-member LLCs (whether owned by US residents or foreign nationals) file Form 1065 and issue a Schedule K-1 to each member showing their share of profits and losses. (Note: Foreign partners in a US multi-member LLC may also need to apply for ITINs and file non-resident personal tax returns depending on the income type.)​
  • Foreign-owned single-member LLCs file Form 5472 and a pro-forma Form 1120 annually. Missing this filing costs $25,000 per LLC, per year — and the IRS does enforce it.

Beneficial Ownership Information (BOI) Report

The BOI requirement has changed significantly since it launched, and what was written about it across most of the internet is now out of date.

The Corporate Transparency Act introduced BOI reporting in January 2024, requiring most US LLCs to disclose their beneficial owners to FinCEN. After a series of legal challenges and court-ordered enforcement pauses, FinCEN issued an interim final rule on March 26, 2025 that removed the requirement for all domestically formed US companies — including LLCs formed in any US state.

US-formed LLCs are currently not required to file a BOI report. Foreign entities that registered to do business in the US may still be subject to the requirement.

The rule is interim and a final rulemaking is pending, so it could change again. Check fincen.gov for the current status before assuming your LLC is exempt.

Real-World LLC Examples

Some of the most recognized companies in the world are structured as LLCs. Google operates as Google LLC under Alphabet Inc. Amazon.com Services LLC is the core US operating entity of Amazon. Chrysler Group LLC carried the automaker through its post-bankruptcy restructuring. Beats Electronics, before its acquisition by Apple, was Beats Electronics LLC.

The LLC is not a "small business only" structure. It's used at every scale because of its flexibility, its liability protections, and — especially for subsidiaries of larger entities — its tax transparency.

Frequently Asked Questions

What is the difference between an LLC and a corporation?

An LLC offers liability protection and pass-through taxation with minimal governance requirements. A C-Corporation has shareholders, a board of directors, and mandatory governance formalities, but can raise venture capital more easily and has a longer legal history. S-Corporations combine pass-through taxation with some corporate structure but are only available to US citizens and residents. For most small businesses and non-US founders, the LLC is the better starting structure. Full comparison: LLC vs. C-Corp.

Do I need to live in the US to form an LLC?

No. Non-US residents can form a US LLC in any US state. You need a registered agent with a US address in your formation state — but that doesn't have to be you. Citizenship and physical presence are not required.

What does "LLC" after a company name mean?

It identifies the business as a registered Limited Liability Company — a legal entity that is separate from its owners. Every US LLC must include "LLC," "L.L.C.," or "Limited Liability Company" in its legal name.

Is an LLC the same as a limited liability corporation?

No. "Limited liability corporation" is a common misnomer. The correct term is Limited Liability Company. A corporation and a company are different legal structures. An LLC is not a corporation.

What is the best state to form an LLC as a non-US resident?

Wyoming is our recommendation for most non-residents: $100 filing fee, $60 minimum/year annual fee, no state income tax, no public disclosure of ownership, and a mature LLC statute. Best US States for Foreigners to Form an LLC.

Do I need an Operating Agreement?

While most states strongly recommend one, several states (like New York, California, and Delaware) legally require it. Even for a single-member LLC in a state where it's only recommended, an Operating Agreement is evidence that your LLC is a real, separate entity — which protects your liability shield and is frequently requested by banks. See LLC Operating Agreement.

What is Form 5472 and who needs to file it?

Form 5472 is an IRS information return required for any US LLC that has a non-US owner and engages in transactions with that owner (contributions, distributions, loans). Foreign-owned single-member LLCs must file it annually alongside a pro-forma Form 1120. The penalty for non-filing is $25,000 per year. Form 5472 + Pro-Forma 1120.

Can I have multiple LLCs?

Yes. There is no legal limit on how many LLCs a person can own, and many founders use separate LLCs to isolate different business lines or assets. Running Multiple LLCs | Multiple Businesses Under One LLC.

What to Do Next

An LLC gives you liability protection, US banking access, and a credible US business identity — without requiring you to be a US citizen, visit the US, or navigate the complexity of a full corporation.

The formation itself is the easy part. Getting the details right from the start — the right state, a proper Operating Agreement, an EIN application that doesn't sit in an IRS queue for 10 weeks, and annual compliance that doesn't catch you off-guard with a $25,000 penalty — is where most people benefit from specialist help.
