Every year, millions of people decide to register a company in the USA — and a surprising number get stuck before they even file the first document. They either pick the wrong business structure, register in the wrong state, or miss a required step that costs them months later.
This guide cuts through the noise. Whether you are a US resident starting a local business or an international founder building a US presence, you will find a clear, honest breakdown of every step — from choosing your entity type to getting your first bank account open.
No fluff. No upselling. Just the process as it actually works in 2026.
What Business Structure Should You Choose?
The right business structure depends on your liability exposure, how you plan to pay taxes, and whether you intend to raise outside investment. Most small businesses and solo founders choose an LLC. Most venture-backed startups choose a C-Corporation. Everything else serves a much narrower use case.
Here is a plain-language comparison of the four main options:
| Structure | Liability Protection | Taxation | Best For |
|---|---|---|---|
| Sole Proprietorship | None — personal assets at risk | Personal income tax | Freelancers testing an idea |
| Partnership | Limited (General) or Partial (LP) | Pass-through to partners | Two or more co-founders, low complexity |
| LLC | Full personal protection | Pass-through (default) or elect corporate | Most small to mid-size businesses |
| C-Corporation | Full personal protection | Double taxation (corp + personal) | Startups seeking VC funding |
| S-Corporation | Full personal protection | Pass-through, strict eligibility | Profitable small businesses reducing self-employment tax |
A few things are worth knowing before you decide:
LLC is the most popular choice for a reason. It protects your personal assets if the business is sued, and the IRS treats it as a “pass-through” entity by default — profits land on your personal tax return, not a separate corporate return. You avoid the double-taxation that C-Corporations face. The paperwork is minimal. Management is flexible.
C-Corporation is the standard for startups that plan to raise venture capital. Most institutional investors will not invest in an LLC because of tax complications. If you are building a company you plan to scale and eventually sell or take public, incorporate as a C-Corp — ideally in Delaware.
S-Corporation is not a separate entity type. It is a tax election made by an LLC or corporation. It allows owners who work in the business to pay themselves a salary and take additional profits as distributions, avoiding self-employment tax on the distribution portion. Worth exploring once your business is consistently profitable.
Sole Proprietorship offers zero liability protection. If your business gets sued, your personal bank account is on the table. Fine for testing an idea, but not a long-term operating structure.
How to Register a Company in the USA: Step-by-Step
To register a company in the USA, you need to choose a business structure, pick a state, file formation documents with that state’s Secretary of State, get an EIN from the IRS, and obtain any necessary licenses. The full process takes one to four weeks in most states and can be done entirely online.
Here is every step in the correct order:
Step 1: Choose Your Business Structure
Use the comparison table above to decide. If you are unsure between an LLC and a C-Corp, a 30-minute consultation with a business attorney or CPA is money well spent at this stage. The structure you choose now affects your taxes, liability, and investor eligibility for years.
Step 2: Pick Your State of Formation
You can register in any US state — you do not need to live there. But here is what most guides do not tell you: if you operate your business in a different state than where you registered, you will likely need to foreign-qualify in your operating state, which means paying fees in both states.
For most US residents, the right answer is your home state. For international founders or businesses with no physical US presence, Delaware and Wyoming are the two most popular choices (more on this below).
Step 3: Choose and Check Your Business Name
Your business name must be unique within your state. Check availability on your state’s Secretary of State website. This search is free and takes about two minutes.
Also check:
- The USPTO trademark database at uspto.gov to avoid infringing on a federally registered trademark
- Domain name availability — even if you do not need a website immediately, securing the matching domain now is inexpensive and prevents future headaches
If you want to operate under a different name than your legal entity name (for example, “Blue River Consulting LLC” doing business as “Blue River”), you will need to file a DBA (Doing Business As) with your state or county.
Step 4: Appoint a Registered Agent
Every US business entity — LLC, corporation, partnership — must designate a registered agent in its state of formation. The registered agent receives legal notices, tax documents, and government correspondence on your company’s behalf.
The registered agent must have a physical street address in the state (not a PO Box) and be available during standard business hours. You can serve as your own registered agent if you have a qualifying address, but most business owners use a registered agent service for about $100 to $300 per year. The benefit: your personal address stays off public records, and you will not miss an important legal notice while traveling.
Step 5: File Your Formation Documents
This is the step that officially creates your business entity. You file with your state’s Secretary of State office (or equivalent agency).
- For an LLC: File Articles of Organization
- For a Corporation: File Articles of Incorporation
- For a Partnership: File a Partnership Agreement or Certificate of Partnership, depending on the state
Filing fees range from $35 (Montana) to $500 (Massachusetts). Most states process online filings within one to seven business days. Delaware processes LLC filings within 24 hours online.
You will need to provide: your entity name, registered agent information, business address, member or officer names, and in some cases a brief statement of business purpose.
Step 6: Get an EIN from the IRS
An Employer Identification Number (EIN) is a nine-digit number the IRS uses to identify your business for tax purposes. Think of it as a Social Security Number for your company. You need it to open a business bank account, hire employees, and file federal taxes.
The EIN is free and can be obtained directly through the IRS website at irs.gov/ein.
- US residents with an SSN: Receive the EIN instantly online.
- Non-US residents without an SSN: Must apply by fax or mail using Form SS-4. Processing takes four to six weeks.
Step 7: Draft Your Operating Agreement or Bylaws
This step is technically optional in most states, but skipping it is a mistake.
An Operating Agreement (for LLCs) or Bylaws (for corporations) defines who owns what percentage of the business, how profits are distributed, how decisions are made, and what happens if an owner wants to leave. Without this document, your business operates under your state’s default rules — which may not match what you and your co-founders actually agreed to.
You can use a free template as a starting point, but have an attorney review it if you have multiple owners or complex ownership terms.
Step 8: Open a Business Bank Account
Do not skip this step or delay it. Mixing personal and business finances is the fastest way to lose the liability protection your LLC or corporation provides — a legal concept called “piercing the corporate veil.”
To open a business bank account, you will typically need: your EIN, formation documents, and an operating agreement or bylaws. Most major banks (Chase, Bank of America, Wells Fargo) and many online banks (Mercury, Relay, Bluevine) offer business checking accounts.
Step 9: Get Required Licenses and Permits
Most businesses need at least one of these at the local, state, or federal level:
- Local business license — issued by your city or county, required for most businesses operating in a fixed location
- State professional license — required for licensed professions (healthcare, law, real estate, accounting)
- Federal license — required for specific regulated industries: firearms dealers, alcohol production, broadcasting, commercial trucking
The SBA’s license and permit tool at sba.gov helps you identify what applies to your industry and location.
Step 10: Register for State Taxes
Depending on your state and business type, you may need to register for:
- State income tax (if your state has one — Wyoming, Nevada, Florida, and eight others do not)
- Sales tax permit — if you sell taxable goods or services
- Employer withholding — if you plan to hire employees
Your state’s Department of Revenue or Department of Taxation handles these registrations. Most can be completed online.
Which State Should You Register Your Company In?
For US residents, register in the state where you live and operate. For non-residents or online businesses without a physical US location, Delaware and Wyoming are the two most commonly recommended options.
Here is the practical breakdown:
Delaware is the gold standard for corporations seeking venture capital. More than 66% of Fortune 500 companies are incorporated in Delaware. The Court of Chancery — a specialized business court with no juries and judges who deeply understand corporate law — gives Delaware a legal predictability that investors and their lawyers have grown comfortable with. Delaware charges a $300 annual franchise tax on LLCs and an $89 filing fee. For corporations, fees vary by share structure.
Wyoming is the better choice for small LLCs, especially non-residents who want low costs and strong privacy. Wyoming charges a $100 formation fee and a $60 annual license tax. There is no state income tax. Wyoming also has some of the strongest asset protection laws in the country and does not require public disclosure of member names.
Nevada markets itself as business-friendly due to no state income tax, but the actual costs are higher than Wyoming — $350 per year in combined annual fees (Annual List: $150 + State Business License: $200). Not the best choice for most founders.
California is worth understanding even if you plan to avoid it. If you form your LLC in Wyoming or Delaware but operate your business in California — meaning you live there, have employees there, or generate significant revenue there — California will require you to register as a foreign LLC and pay its $800 annual franchise tax regardless. Trying to avoid California’s franchise tax by forming elsewhere usually backfires.
The honest default: If you live and work in the US, form your LLC or corporation in your home state. The savings from registering in a “cheaper” state disappear the moment you have to also pay foreign qualification fees and annual reports in your home state.
How Much Does It Cost to Register a Company in the USA?
The one-time state filing fee to register an LLC in the USA ranges from $35 to $500. The average across all 50 states is $132 as of 2026.
But the filing fee is only part of the real cost. Here is what to budget for:
| Cost Item | Typical Range | Notes |
|---|---|---|
| State filing fee (one-time) | $35 – $500 | Lowest: Montana ($35), Highest: Massachusetts ($500) |
| Registered agent service (annual) | $100 – $300 | Required in every state |
| Operating agreement / bylaws | $0 – $500 | Free templates or attorney-drafted |
| EIN | Free | Applied directly through IRS |
| Business bank account | $0 – $25/month | Many online banks are free |
| Annual report / franchise tax | $0 – $800+ | California: $800 minimum; New Mexico: $0 |
| Business licenses | $50 – $500+ | Varies widely by industry and location |
Total first-year cost for most businesses: $200 to $800 in most states. California and Massachusetts can run significantly higher due to annual fees.
A few states that stand out:
- Arizona, Missouri, New Mexico, Ohio — No annual report fee after formation. You pay once to form and that is it (outside of potential local licenses).
- California — $70 filing fee plus $800 minimum franchise tax every year, regardless of income. Even a dormant LLC in California owes $800.
- New York — Requires LLCs to publish a formation notice in two local newspapers for six consecutive weeks. Depending on the county, that publication requirement costs $300 to $1,500.
Common Mistakes First-Time Founders Make
Most registration problems are preventable. These are the ones I see come up repeatedly when founders look back at what went wrong early in their business.
Forming in a “cheap” state when you operate somewhere else. Registering in Wyoming to avoid California’s franchise tax while living and working in California is one of the most common and costly mistakes. You end up paying Wyoming’s fees plus California’s fees — more than if you had simply formed in California to begin with.
Skipping the Operating Agreement. Many states do not require it. That does not mean you should skip it. Without one, your LLC operates under your state’s default rules, which might distribute profits equally regardless of how much each person invested or contributed.
Using a personal bank account for business. If someone sues your LLC and discovers you have been running personal expenses through it, a court can “pierce the corporate veil” and hold you personally liable — eliminating the entire point of forming an entity with liability protection.
Missing annual report deadlines. Every state that requires annual reports has a deadline. Missing it puts your business in “not good standing” status. Continued non-payment leads to administrative dissolution. Reinstatement requires paying back fees plus penalties — typically $50 to $200 on top of what you owe.
Choosing the wrong structure for future fundraising. If you form an LLC and then want to take on venture capital, you will likely need to convert to a C-Corporation. That process is possible but adds time, cost, and legal complexity. If raising outside capital is part of your five-year plan, start as a C-Corp in Delaware.
Not getting an EIN immediately. Some founders delay this step. Without an EIN, you cannot open a business bank account, hire employees, or properly file taxes. It is free and takes minutes for US residents. Do it as soon as your formation documents are approved.
Frequently Asked Questions
Can a non-US citizen register a company in the USA?
Yes. There are no federal or state laws requiring US citizenship or residency to own an LLC or C-Corporation in the United States. Non-residents can form a company in any state. The main additional steps are: appointing a registered agent, applying for an EIN by fax or mail (since the online system requires a US SSN), and setting up a business bank account, which some banks require in-person for non-residents. Delaware, Wyoming, and New Mexico are the most popular states for international founders due to low costs and minimal ongoing requirements.
How long does it take to register a company in the USA?
Most states process LLC or corporation filings within one to seven business days for standard online submissions. Delaware offers 24-hour processing by default. States like Wyoming and Colorado also tend to process filings in one to two business days. After state approval, non-residents should expect four to six weeks to receive an EIN by mail. US residents with an SSN receive their EIN instantly through the IRS online system.
Do I need a US address to register a company?
You do not need a personal US address, but your registered agent must have a physical US address in the state of formation. The registered agent address is what appears on your company’s public filings. If you are a non-resident, a registered agent service ($100 to $300 per year) handles this requirement and keeps your personal address off public records.
What is the difference between an LLC and a corporation?
An LLC (Limited Liability Company) is more flexible and simpler to maintain. Profits and losses pass through to owners’ personal tax returns by default, and there are fewer ongoing formalities than a corporation. A corporation is a separate legal entity that files its own tax return. C-Corporations face double taxation (corporate tax on profits, then personal tax on dividends) but are structured for equity fundraising, stock issuance, and eventual IPO or acquisition. Most small businesses choose LLCs. Most startups seeking venture capital choose C-Corporations.
Do I need a lawyer to register a company in the USA?
No. You can complete the entire registration process without a lawyer using your state’s Secretary of State website, the IRS website for your EIN, and free operating agreement templates. That said, if you have multiple founders, complex ownership arrangements, or plans to raise outside capital, spending $500 to $2,000 on a business attorney upfront prevents disputes that can cost far more later.
What is a registered agent and do I really need one?
A registered agent is a person or company authorized to receive legal and official government documents on behalf of your business during regular business hours. Every LLC and corporation in the US must have one. You can serve as your own registered agent if you have a physical address in the formation state, but most business owners use a professional service to protect their privacy and ensure they never miss a notice while traveling or away from their address.
Can I register a company online?
Yes, in most states. The majority of US states allow you to file LLC or corporation formation documents entirely online through the Secretary of State’s website. Some states still accept or require paper filings, though online submission is faster. The IRS EIN application is also available online for those with a US Social Security Number.
What is a Beneficial Ownership Information (BOI) report?
Under the Corporate Transparency Act of 2021, most US companies are required to file a Beneficial Ownership Information report with the Financial Crimes Enforcement Network (FinCEN), a bureau of the US Treasury. This report discloses the individuals who ultimately own or control the company. Newly formed companies must file this report within 90 days of formation. The FinCEN e-filing system is free. Failure to file can result in civil and criminal penalties.
Conclusion
Registering a company in the USA is a manageable process when you understand the steps and avoid the common pitfalls. The core sequence is: pick your entity type, choose a state, file your formation documents, get your EIN, set up your operating agreement, open a business bank account, and handle your licenses.
The biggest decisions — entity type and state of formation — deserve careful thought before you file anything. For most small businesses, an LLC in your home state is the right answer. For startups raising venture capital, a Delaware C-Corporation. For non-residents building an online business, Wyoming or New Mexico offer low ongoing costs.
Your next step: Visit your state’s Secretary of State website to check your intended business name. Name availability takes two minutes and costs nothing. Once you confirm the name is clear, the rest of the process follows logically from there.
