How to Start an LLC in the U.S. in 2026

Starting a limited liability company can be one of the first major legal steps in turning a business idea into a formal organization.

An LLC is created under state law and can provide owners with liability protection while offering flexibility in management and federal tax treatment.

However, forming an LLC involves more than filing one document. You may need to choose an available business name, appoint a registered agent, file formation documents, obtain an Employer Identification Number, register for taxes and licenses, and comply with ongoing state requirements.

This 2026 guide explains the general process for starting an LLC in the United States. Because LLC laws and filing requirements vary by state, always verify the current rules with the state agency where you plan to form the company.

What Is an LLC?

A limited liability company, or LLC, is a business structure created under state law.

The U.S. Small Business Administration explains that business structure affects personal liability, taxes, paperwork, and the ability to raise money.

LLCs are commonly used because owners generally are not personally liable for the company's debts and obligations solely because they own the business, although liability protection is not unlimited.

LLCs can generally have one or more owners, known as members.

Federal tax treatment is separate from state legal status. The IRS may treat an LLC as:

• An entity disregarded as separate from its owner
• A partnership
• A corporation

The default federal classification depends primarily on the number of members and whether the LLC makes a tax election.

1. Choose the State Where You Will Form the LLC

Before selecting a name or filing paperwork, decide where the LLC should be organized.

For many small businesses, forming in the state where the business actually operates is the simplest option.

Forming in another state simply because that state is popular for businesses can create additional obligations. If your company conducts business in a different state from the one where it was formed, you may need to register there as a foreign LLC and pay additional filing fees, taxes, or annual charges.

Before choosing another state, consider:

• Where the business will actually operate
• State formation fees
• Annual or periodic filing fees
• State taxes
• Registered agent costs
• Foreign registration requirements
• Industry licensing requirements

For a simple local business, forming in the home state is often the most straightforward approach.

2. Choose Your LLC Name

Your LLC name must comply with the naming rules of the state where the company is formed.

Common requirements include using a designator such as:

• Limited Liability Company
• LLC
• L.L.C.

States can also restrict or regulate certain words associated with banks, insurance companies, government agencies, professional services, and other regulated industries.

Before filing, search your state's business database to determine whether the desired name is available.

Check for Trademark Problems Too

State name availability does not automatically mean you are free to use the name commercially throughout the United States.

A business name can potentially conflict with an existing trademark even if the state allows you to register the LLC.

Consider searching the U.S. Patent and Trademark Office database and performing broader research before investing heavily in branding.

You may also want to check whether a suitable domain name and relevant social media usernames are available.

3. Appoint a Registered Agent

States generally require LLCs to designate a registered agent or similar official contact for legal and government documents.

The registered agent normally must maintain a physical address in the state where the LLC is registered and be available to receive official documents.

Depending on state law, the registered agent may be:

• The business owner
• Another qualifying individual
• A professional registered agent company

Using yourself as registered agent can reduce costs, but it may place your address in public business records and requires reliable availability for official notices.

A professional service can be useful for owners who travel frequently, operate from home, or prefer not to use a personal address where permitted.

4. File the LLC Formation Document

The document used to create an LLC is often called the Articles of Organization, although some states use terms such as Certificate of Organization or Certificate of Formation.

The filing is generally submitted to the Secretary of State or another business registration agency.

The information requested may include:

• LLC name
• Business address
• Registered agent information
• Management structure
• Organizer information
• Business purpose where required

Filing fees vary significantly by state.

Do not rely on a national average when planning your startup costs. Check the current filing fee directly with the state agency because fees and procedures can change.

What Happens After Approval?

After the state accepts the formation filing, it may issue a certificate or other confirmation showing that the LLC has been created.

Keep that document with the company's permanent records.

Banks, lenders, licensing agencies, and other organizations may request proof that the LLC is properly registered.

5. Create an Operating Agreement

An operating agreement explains how the LLC will be owned and managed.

Whether an operating agreement is legally required varies by state, but creating one can still be valuable even when state law does not require filing it.

A strong operating agreement can address:

• Ownership percentages
• Capital contributions
• Voting rights
• Management responsibilities
• Profit and loss allocations
• Distributions
• Admission of new members
• Departure or death of a member
• Transfer of ownership interests
• Dispute procedures
• Dissolution of the company

A single member LLC can also benefit from an operating agreement because it documents the company's structure and internal rules.

Businesses with several owners should consider professional legal assistance when drafting provisions involving ownership, voting, transfers, or disputes.

6. Obtain an EIN When Required or Useful

An Employer Identification Number is a federal tax identification number issued by the Internal Revenue Service.

The IRS provides EINs directly at no charge.

Businesses may need an EIN for reasons including:

• Hiring employees
• Operating under certain tax classifications
• Opening some business bank accounts
• Applying for licenses or business credit
• Filing certain federal tax returns

Not every single member LLC automatically needs a separate EIN for every federal tax purpose, so the requirement depends on the company's circumstances and tax classification.

Apply through the IRS rather than paying an unrelated company simply to obtain the number.

7. Understand How the LLC Will Be Taxed

Forming an LLC does not create one universal federal tax treatment.

For federal income tax purposes, the IRS generally treats a domestic LLC with one member as an entity disregarded as separate from its owner unless it elects corporate treatment.

A domestic LLC with two or more members is generally treated as a partnership unless it elects to be treated as a corporation.

LLC Structure	Typical Default Federal Treatment
One member	Entity disregarded as separate from the owner
Two or more members	Partnership
Eligible LLC making an election	Corporation or S corporation when requirements are met

An LLC can potentially elect corporate treatment using the applicable IRS procedures.

An eligible LLC can also elect S corporation status if it meets the requirements.

These elections can have significant tax consequences, so business owners should consider discussing them with a qualified tax professional rather than making the decision based solely on social media advice or potential payroll tax savings.

8. Open a Dedicated Business Bank Account

Once the LLC is established, consider opening a dedicated business bank account.

Separating business and personal transactions can make bookkeeping, tax preparation, financial reporting, and business administration considerably easier.

A bank may request documents such as:

• Approved formation documents
• EIN or other tax identification information
• Operating agreement
• Owner identification
• Business license information where applicable

Requirements vary by financial institution.

Why Financial Separation Matters

An LLC provides a legal structure separate from its members, but owners should still treat the company as a separate business.

Mixing personal and company finances can create poor records and may become one factor considered in disputes involving whether the business was genuinely operated as a separate entity.

Using a dedicated account does not by itself guarantee liability protection, but it is an important business practice.

9. Obtain Required Business Licenses and Permits

Creating an LLC does not automatically give a business permission to conduct every type of activity.

Depending on the industry and location, additional requirements may include:

• Local business licenses
• Professional licenses
• Sales tax permits
• Health department permits
• Zoning approvals
• Building permits
• Occupational licenses
• Industry specific federal permits

Check federal, state, county, and city requirements applicable to your particular business.

A license required in one location may not exist in another.

10. Register for State and Local Taxes

Tax registration requirements depend on what your company does and where it operates.

Potential obligations can include:

• Sales and use tax
• Employer withholding
• State unemployment taxes
• Franchise taxes
• Gross receipts taxes
• Local business taxes

Do not assume that having no federal corporate income tax automatically means the LLC has no state tax obligations.

Some states impose annual taxes or fees on LLCs even when the business has little or no taxable income.

11. Understand Current BOI Reporting Rules

This is an area where older LLC formation guides can now be misleading.

Under the Corporate Transparency Act, beneficial ownership reporting requirements changed substantially.

FinCEN issued a final rule in August 2026 that permanently exempts companies created in the United States from federal beneficial ownership information reporting requirements.

As a result, a domestic LLC formed in the United States is currently not required to file a BOI report with FinCEN solely because it was created under state law.

Certain foreign companies registered to do business in the United States can still be subject to reporting requirements.

Because this area has changed several times, businesses should check FinCEN's current guidance rather than relying on older articles or formation checklists.

12. Keep the LLC in Good Standing

Formation is not the final compliance step.

States can require ongoing filings and fees such as:

• Annual reports
• Biennial reports
• Franchise taxes
• Annual registration fees
• Registered agent maintenance
• License renewals

Deadlines and fees vary significantly by state.

Missing required filings can result in penalties, loss of good standing, or administrative dissolution.

A simple compliance calendar can help track:

• Annual report deadlines
• Tax filing deadlines
• License renewals
• Registered agent renewals
• Insurance renewals
• Other state and local obligations

How Much Does It Cost to Start an LLC?

There is no single nationwide LLC formation price.

Your total cost can include:

Potential Cost	What Determines It
State filing fee	State where the LLC is formed
Registered agent service	Whether you hire a professional service
Local licenses	Industry and location
State annual fees	State requirements
Legal assistance	Complexity of ownership and agreements
Tax assistance	Tax elections and business complexity

The state filing fee is only the beginning. Compare ongoing costs before deciding where to form the company.

Should You Use an LLC Formation Service?

A formation service can be useful if you want assistance preparing and submitting standard filing documents.

However, these services are optional in many straightforward situations.

Before paying for one, compare:

• Service fee
• State filing fee
• Registered agent charges
• Automatic subscription renewals
• Compliance packages
• Cancellation terms

Some companies advertise formation for very little money but charge separately for registered agent service, EIN assistance, operating agreement templates, compliance alerts, and other extras.

Remember that an online filing service is not automatically a substitute for legal or tax advice.

If your LLC has multiple owners, complicated ownership rights, investors, unusual tax circumstances, or significant liability exposure, professional advice can be more valuable than a generic formation package.

Can You Start an LLC Yourself?

In many states, business owners can file standard LLC formation documents directly through the state's business registration website.

A straightforward single owner LLC may not require a professional formation company.

However, doing it yourself means you are responsible for understanding:

• State filing requirements
• Registered agent rules
• Licenses and permits
• Tax registrations
• Annual filings
• Operating agreement needs

The filing itself may be simple. Choosing the correct business structure and tax treatment can be the more important decision.

Example: Starting a Simple Single Member LLC

Imagine Jordan wants to start a small digital marketing business.

A simplified formation process might look like this:

Step	Action
1	Confirm that an LLC is an appropriate structure
2	Choose the state of formation
3	Search the desired business name
4	Choose a registered agent
5	File the state's LLC formation document
6	Create an operating agreement
7	Obtain an EIN if needed
8	Open a business bank account
9	Register for required licenses and taxes
10	Create a calendar for future compliance deadlines

Jordan's actual requirements would depend on the state, city, services offered, employees, and tax treatment.

FinanceHub USA Analysis: Formation Is Only the First Step

Many LLC formation guides focus so heavily on filing the Articles of Organization that they make the process sound finished once the state accepts the document.

In reality, the filing only creates the legal entity.

The business still needs functioning financial and administrative systems.

A strong foundation can include:

• A dedicated bank account
• Accurate bookkeeping
• Required insurance
• Proper contracts
• Tax planning
• Licenses and permits
• Clear ownership documentation
• Compliance reminders

The objective should not be to create an LLC as quickly as possible. It should be to create a business structure that you understand and can maintain correctly.

Common LLC Formation Mistakes

1. Forming in another state without understanding the consequences. You may create additional registration and compliance obligations.
2. Assuming the LLC automatically determines your federal taxes. Federal tax classification is a separate issue.
3. Ignoring an operating agreement. Clear internal rules are especially important when there is more than one owner.
4. Mixing personal and business transactions. Separate financial records make administration and accounting easier.
5. Forgetting licenses and permits. State formation alone may not authorize the business activity.
6. Missing annual state filings. Good standing can depend on ongoing compliance.
7. Paying unnecessary fees for an EIN. The IRS issues EINs directly without a fee.
8. Assuming old BOI guidance still applies. Domestic U.S. companies are currently exempt from FinCEN BOI reporting.
9. Choosing a tax election without professional analysis. An election can affect payroll, federal taxes, administration, and future changes.

Final Thoughts

Starting an LLC in the United States is usually a state based process, but the consequences extend into federal taxes, banking, licensing, and ongoing compliance.

Begin by deciding whether an LLC fits your business and where the company should be formed. Then choose an available name, appoint a registered agent, file the required formation document, and create an operating agreement.

After formation, determine whether you need an EIN, establish business banking, understand the LLC's federal tax classification, obtain necessary licenses, and register for applicable taxes.

Finally, keep track of ongoing state requirements so the company remains in good standing.

Do not rely on one national checklist for every detail. LLC requirements can vary considerably by state, industry, and tax situation.

The most useful approach is to combine your state's official formation guidance with current IRS, SBA, and other government information relevant to your business.
