How to start an LLC: Guide for US and international founders

Wondering how to start an LLC? This guide covers everything you need to know, whether you're based in the United States or forming from a foreign country.

There are roughly 36.2 million small businesses in the United States (according to the SBA Office of Advocacy's 2025 small business profiles), and around 21.6 million of them are LLCs, or Limited Liability Companies.

Founders form LLCs to reduce personal liability, access flexible tax treatment, and open business bank accounts.

So how do you start an LLC? What’s involved? And how long does it take?

This guide walks through each step of formation in detail, plus what an LLC actually is, what it costs, how it's taxed, and what to do once yours exists.

Starting an LLC: the 7 steps at a glance

There are typically 7 steps to forming an LLC:

1. Select your formation state
2. Choose and check your LLC name
3. Appoint a registered agent
4. File your Articles of Organization
5. Create an operating agreement
6. Get an EIN from the IRS
7. Complete state and local registrations and licenses

To complete all seven steps, founders should expect a timeline of a few days all the way up to six weeks end to end. If you'd rather skip them, you can form an LLC with Whop, which handles all of it in one flow (including for founders outside the US).

We'll break down each of these 7 steps below, in detail.

What is an LLC?

An LLC (Limited Liability Company) is a type of business structure in the United States that creates a legal separation between a business and its owner or owners.

Unlike a sole proprietorship (where you and your business are legally considered the same entity) an LLC exists as its own legal entity. This separation is where the "limited liability" part comes in.

For example, if your LLC takes on debt or faces a lawsuit, your personal assets generally aren't used to cover the business's liabilities (unlike with a sole proprietorship).

LLCs are formed at the state level rather than federally, so the exact rules and requirements depend on the state you register in.

How an LLC works

LLCs combine some of the characteristics of a corporation, with the relative simplicity and flexibility of other business structures.

Like a corporation, an LLC creates a separate legal entity and provides its owners with limited liability protection. But LLCs skip most corporate formalities — no board of directors, no shareholder meetings.

There's also flexibility in how LLCs are taxed. The IRS doesn't recognize an LLC as a separate federal tax classification. So instead, how your LLC is taxed depends on how many people own it and whether you elect a different tax treatment.

For federal income tax purposes, a single-member LLC is treated as a 'disregarded entity' by default: its income and expenses are reported on the owner's federal income tax return.

A multi-member LLC is taxed as a partnership by default, and eligible LLCs can also elect to be taxed as corporations (more on this later).

Single-member vs multi-member LLCs

The people who own an LLC are called members, and an LLC can have one or multiple members.

A single-member LLC (SMLLC) has, as it sounds, one owner. This is a common option for solo business owners who want to create a separate legal entity without bringing another person into the company.

Multi-member LLCs (MMLLC) have two or more owners. With this structure, each member can have an ownership stake in the company.

An operating agreement sets out each member's rights, responsibilities, voting power, and share of profits.

There's no federal requirement for members of a multi-member LLC to be individuals, either. Depending on the circumstances, members can include individuals, other LLCs, and corporations. Most states don't impose a maximum number of members.

Member-managed vs manager-managed LLCs

LLC ownership and management aren't necessarily the same thing.

Most LLCs are member-managed, meaning the owners are directly involved in running the business. Members can make decisions, enter into contracts on behalf of the LLC, and handle its day-to-day operations.

An LLC can instead be manager-managed. In this structure, the members appoint one or more managers to run the business. A manager can be a member of the LLC, but doesn't necessarily have to be.

A manager-managed structure can make sense when an LLC has passive members who don't want to participate in everyday operations, or when there are enough members that having everyone involved in every decision would be impractical.

Which structure you choose can affect who has the authority to act on behalf of your LLC, so it's something you'll need to decide when setting the business up.

When to form an LLC

The decision depends on what your business does, the risks involved, how much you're earning, whether you're working with other people, and how much administration you're prepared to take on.

Here's how an LLC compares to the two structures founders most often weigh it against:

LLC vs sole proprietorship vs corporation

Do I need an LLC yet?

Not necessarily. If you're making the occasional sale from a new side hustle, staying a sole proprietor costs nothing, requires no filings, and carries no penalty.

You can form an LLC later and move the business into it once there's something worth protecting.

But if you're signing contracts, working with clients, selling a high volume of products, or starting a business you expect to grow, forming sooner starts to pay for itself.

The benefits of starting an LLC

The most obvious advantage of starting an LLC is limited personal liability.

If you operate as a sole proprietor, there's generally no legal separation between you and your business. So as a result, business debts and liabilities are ultimately your responsibility.

An LLC creates a separate legal entity, which generally means your personal assets aren't on the line for debts and liabilities belonging solely to the company.

LLCs also benefit from pass-through taxation. This means the LLC itself generally doesn't pay federal income tax on its profits. Instead, the profits "pass through" to the owner or members, who report their share on their individual tax returns.

This avoids the double taxation that can apply to C corporations, where profits may be taxed once at the corporate level and again when distributed to shareholders as dividends.

And there are other benefits, too:

• Flexible ownership: LLCs can have one or multiple members.
• Flexible management: You can run the LLC yourselves or appoint one or more managers.
• Fewer corporate formalities: LLCs generally don't require the same formal governance structure as corporations.
• Business banking: An LLC can obtain an EIN and open financial accounts in the business's name.
• Clearer separation: Operating through a separate entity can make it easier to distinguish business finances, contracts, assets, and obligations from your personal affairs.

How to start an LLC in 7 steps

If, after reading through the above, you've decided an LLC is right for you, here’s how to make it official.

LLCs are formed at state level, which means there isn't one universal application or set of requirements for every business in the US. You'll need to follow the rules of the state where you choose to register.

That said, the process follows the same general path across the country. Here's how to start an LLC in seven steps.

Step 1: Choose the state where you'll form your LLC

For most small business owners, the simplest option is to form your LLC in the state where you live and primarily do business.

You can register elsewhere (Delaware and Wyoming are popular for their business laws and privacy), but forming away from where you actually operate usually means registering at home anyway as a foreign LLC, with a second set of fees.

Step 2: Choose and check your LLC name

Next up, what are you going to call your LLC? Registering means your company needs an official legal name.

Rules vary between states, but your name will generally need to be distinguishable from other business entities already registered in that state. You'll also typically need to include wording that identifies the business as an LLC, such as 'LLC', 'Limited Company', etc.

The exact permitted variations depend on the state you register in.

You can start by finding the business entity search provided by the Secretary of State or equivalent in the state you're registering in. Search the name you want to see what's already registered.

If your chosen name is available but you aren't ready to form your LLC yet, your state may allow you to reserve the name for a set period.

This is optional and usually involves a separate application and fee.

Check for trademarks

An available LLC name doesn't necessarily mean you're free to build a brand around it.

State business registration and federal trademark protection are two different things. Registering an entity name generally protects that name at state level for business registration purposes. A federal trademark can provide broader protection for a brand used with particular goods or services.

Before committing to a name, run your name through the US Patent and Trademark Office's official trademark search tool for identical or confusingly similar marks.

It's also worth checking domain name availability, social media handles, and doing a web search for businesses using the same or a similar name.

Doing this now can be much easier than discovering a naming problem after you've created a website, printed packaging, and started attracting customers.

Trading under a different name

Your legal LLC name doesn't necessarily have to be the name customers see.

You may be able to use a DBA (doing business as), also known in some jurisdictions as a fictitious, assumed, or trade name. For example, you could have an LLC with one legal name and operate a particular store or brand under another.

And you guessed it, DBA requirements also vary by location. While your LLC itself is formed at state level, DBA registration may require you to register the name with your state, county, or city.

Step 3: Choose a registered agent

Before you file your formation documents, you'll generally need a registered agent in your chosen state. This is the person or company officially designated to receive legal and government documents on behalf of your LLC.

Think of them as the state's reliable point of contact for your company: if your LLC is served with legal papers or receives certain official notices, there needs to be somewhere those documents can actually go.

Registered agent requirements vary by state, but the agent generally needs:

• A physical street address in the state where the LLC is registered
• To be available at that address during normal business hours
• To meet any other eligibility requirements imposed by the state

A PO box alone generally won't satisfy a requirement for a physical registered office.

Can I be my own registered agent?

Yes, in most states you can be your own registered agent, which can save you the cost of paying for a service.

But be sure to consider what that involves before automatically putting your own name down.

Your registered office information may become part of the public record. If you run your business from home, that could mean using your home address.

You also need to be reliably available at the registered address – if you're constantly traveling, working from different locations, or simply don't want legal documents arriving at your workplace or home, acting as your own agent may not be practical.

The alternative is a commercial registered agent service. You pay the provider to act as your registered agent and receive relevant documents for your LLC.

Step 4: File your Articles of Organization

You've chosen your state, found a name, and sorted your registered agent. Congrats! Now you can actually create your LLC.

You'll do this by filing a formation document with the relevant state agency (most commonly the Secretary of State), and paying the required filing fee.

In many states, this document is called the Articles of Organization.

The information required varies, but you can typically expect to provide details such as:

• Your LLC's legal name
• Its principal business address
• Your registered agent's name and address
• Whether the LLC is member-managed or manager-managed
• The name or details of the person forming the LLC
• The purpose of the business, where required

Depending on the state, you may need to provide additional information about members or managers.

Once your filing is accepted, the state will provide confirmation or an approved formation document. Keep it safe, as banks and other institutions will ask for it.

Step 5: Create an operating agreement

Your Articles of Organization act as the document that tells the state your LLC exists. But your operating agreement is the internal document that establishes how the people inside that LLC will work together.

This becomes especially important with a multi-member LLC.

An operating agreement gives you somewhere to answer important questions before they become arguments.

Do single-member LLCs need an operating agreement?

In most states, no, but it's still worth having one. An operating agreement documents your ownership and management structure, helps demonstrate the LLC is a real, separate entity, and is often requested by banks.

You don't submit it with your Articles of Organization; it stays with your LLC's internal records.

Step 6: Get an EIN from the IRS

With your LLC formed, you can apply for an Employer Identification Number, better known as an EIN.

You can think of your EIN as an identifying number for your business when dealing with federal tax administration. Despite having employer in the name, EINs aren't only relevant if you're hiring employees.

Businesses may need an EIN to operate as a partnership or corporation, meet certain federal tax obligations, open a business bank account, or meet state tax or registration requirements. They're free to get through the IRS.

Most new single-member LLCs will need an EIN under the IRS's current 'Do you need an EIN?' criteria.

Multi-member LLCs do generally require an EIN because they're treated as partnerships by default for federal tax purposes.

Getting an EIN without an SSN

You don't need a Social Security Number (SSN) or US residency to get an EIN. If you're a foreign applicant without an SSN or ITIN, you can still apply using Form SS-4.

The process can take longer for international applicants, though.

Step 7: Complete your state and local registrations and licenses

Check your state and local government requirements as soon as your LLC is approved, and register for anything your business needs.

What applies depends on your business and location, and can include:

• State tax registrations, such as sales or employer taxes
• Federal, state, or local licenses and permits
• Zoning or other location-specific permits
• An initial state report, where required

You'll also need to keep the LLC in good standing over time – annual or biennial reports, fees or franchise taxes, a maintained registered agent, and license renewals. Put every recurring deadline in your calendar now.

Then it's on to what to do after forming your LLC – banking, accounting, and actually running the company.

But first, let's answer the first questions everyone has: how long this takes, what it costs, and how you'll be taxed.

How long does it take to register an LLC?

The LLC formation process can take anywhere from a few days to six weeks. Your biggest variable is how quickly your state processes your formation documents, but other steps can add time too.

Some states offer expedited or even same-day LLC processing for an additional fee.

International founders should allow extra time for their EIN. If you form through Whop without an SSN, your EIN can take up to eight weeks, unless you choose expedited processing.

How much does it cost to start an LLC?

There's no universal price because every state sets its own fees — from $35 in Montana to $500 in Massachusetts, per each state's current fee schedule. Check the exact fee directly with the state where you're forming your LLC.

Below is a rough guideline to costs.

How are LLCs taxed?

Now onto the big question: tax. The IRS taxes your LLC based on how many owners it has and whether you elect a different status.

By default, LLCs use pass-through taxation: profits pass through to the owners, who report them on their personal returns. The IRS's Limited Liability Company guidance covers the default classifications and elections in detail.

Single-member LLCs

The IRS treats a single-member LLC as a disregarded entity by default. You still have a legally separate LLC, but for federal income tax purposes its income is treated as yours. You report the LLC's income and expenses on your own return rather than the LLC filing separately.

Multi-member LLCs

An LLC with two or more owners is taxed as a partnership by default. The LLC reports its income, deductions, profits, and losses to the IRS; each member is allocated their share and reports it on their individual return.

Profits pass through to owners rather than being taxed at the company level first.

Electing C corporation taxation

An LLC can elect to be taxed as a C corporation instead. The LLC then pays federal corporate income tax on profits, and owners pay tax again on any dividends (that's what's known as "double taxation"). Whether it makes sense depends on how your business uses its profits.

Electing S corporation taxation

Eligible LLCs can also elect S corporation treatment, which keeps pass-through taxation but changes how owner-employees are paid: you must pay yourself a reasonable salary (subject to employment taxes), and additional profits can be taken as distributions, which aren't subject to self-employment tax the same way.

This can reduce employment taxes as profits grow, which is why you hear about founders switching.

Self-employment tax

If you run a single-member LLC, you'll pay self-employment tax — Social Security and Medicare – on your business profits, alongside income tax.

Employees split these taxes with their employer; self-employed owners pay both portions.

Multi-member LLC owners may also owe it, depending on their role and income type. Forming an LLC doesn't by itself reduce this tax; electing a different treatment such as S corp status can change how some income is taxed.

Starting an LLC from outside the US

You don't need to be a US citizen or resident to form an LLC. If you live abroad, the formation process follows many of the same steps: choose a state, select a name, appoint a registered agent, file your formation documents, and obtain an EIN.

However, there are some important differences:

• You won't have a home state to default to, so you'll need to choose where to form your LLC. You'll also need a registered agent with a physical address in that state.
• While you don't need an SSN to get an EIN, international applicants without one typically need to use a different IRS application process, which can take longer (Whop can expedite this process for you).
• Tax is where things get a bit more complicated. A foreign-owned US LLC can have US tax and reporting obligations even when its owner doesn't live in the country. Your obligations can also depend on where you live, where your income comes from, how your LLC operates, and any applicable tax treaty.

What to do after forming your LLC

Once your LLC is official and you've checked off all 7 steps, it's time to get set up for operating as an actual company.

Open a business bank account

Opening a dedicated business bank account is one of the first things to do after forming your LLC.

Keeping business money separate makes it a lot easier to track income and expenses, manage taxes, and understand how your business is performing. Banks typically ask for your EIN, formation documents, operating agreement, and personal ID to open an account.

Once it's open, use it as the business account it is: have customers pay the LLC, pay business expenses from the LLC's account, and document money moving between you and the company.

Avoid routinely paying personal expenses with company funds or business expenses from your personal account.

Clear separation makes bookkeeping easier and helps demonstrate the LLC genuinely operates independently from you.

Set up your accounting and recordkeeping

Don't wait until tax season to figure out where your money went.

Set up a bookkeeping system from the beginning to record your revenue, expenses, invoices, assets, debts, and other transactions. This could be accounting software, a professional bookkeeper, or a simpler system if your business is still small.

Remember those documents we said to keep tucked away earlier? You should keep records of your Articles of Organization, operating agreement, EIN confirmation, state filings, licenses and permits, and any major contracts.

Organized documentation will make tax filings, financing, audits, and future business changes much easier.

Consider business insurance

An LLC protects you; it doesn't protect the business. Insurance is what covers the losses and claims the company itself faces.

The coverage you need depends on what you do. Common options include general liability, professional liability, commercial property, and workers' compensation insurance.

Don't want to form an LLC on your own? Use Whop instead

You can start an LLC on your own, but it means juggling a lot of paperwork before weeks of waiting.

Or, founders can register an LLC with Whop through a single process that handles filing, appointing an agent, and registering your EIN for you (even if you're not a US resident).

That means you can spend less time navigating forms and state websites, and more time actually building your business.

Starting an LLC FAQs

What's the difference between an LLC and a sole proprietorship?

A sole proprietorship is just you doing business. There’s no separate entity, no liability protection, and nothing to file. An LLC is a separate legal entity that shields your personal assets from most business debts and lawsuits, in exchange for a filing fee and light ongoing compliance.

Can I start an LLC for free?

No. Even "free" formation services charge the mandatory state filing fee ($35–$500) on top, and typically sell the registered agent and EIN filing as paid extras. The state fee is the one cost nobody can waive.

Do I need a lawyer to start an LLC?

No, you don't need a lawyer. State filing processes are designed for founders to complete themselves, and most straightforward LLCs are formed without one. Legal help earns its fee for multi-member operating agreements, unusual ownership structures, or regulated industries.

Can I form an LLC in a state I don't live in?

Yes, you can form an LLC in any state. However, if you conduct business in your home state, you'll usually need to register the out-of-state LLC there anyway (foreign qualification). That means two sets of fees and filings instead of one. Forming in your home state is the practical choice for most US founders.

Can a non-US citizen own an LLC?

Yes, non-US citizens can form an LLC as there's no citizenship or residency requirement. You'll need a registered agent with a physical address in your formation state, and without an SSN your EIN comes via Form SS-4, which takes longer.

Do I need an EIN for my LLC?

Multi-member LLCs need an EIN, while a single-member LLC with no employees and no excise tax liability can technically skip it for federal income tax purposes. However, banks and payment processors almost always require one. It's free to get an EIN from the IRS, so get it anyway.

Why do people form LLCs in Delaware or Wyoming?

People form LLCs in Delaware for its business laws and specialized court system. Wyoming is popular for low fees, no state income tax, minimal reporting requirements, and owner privacy. These benefits can suit non-US founders, while US founders may still need to register and pay fees where they operate.
