Company formations are the process of legally establishing a business entity by selecting an appropriate structure and completing required registrations to create a recognized legal presence. The formal industry term for this process is “business incorporation,” though company formation is widely used across both U.S. and UK contexts. Getting this right from day one protects your personal assets, determines how you pay taxes, and defines how your business operates legally. Whether you are forming a U.S. LLC as a non-resident or incorporating in the UK, the steps, costs, and compliance requirements differ significantly. This guide covers both jurisdictions with practical tools and updated 2026 details.

What business structure is right for your company formation?

Your choice of business structure determines the federal tax form you will file and is the first decision you must make before any registration begins. The IRS treats this as the foundation of all tax and legal obligations. Choosing the wrong structure early creates expensive corrections later.

The five most common structures in the U.S. are sole proprietorship, partnership, LLC, S corporation, and C corporation. Each carries different liability protection, tax treatment, and administrative requirements.

An LLC is the most popular choice for small business owners and non-residents because it combines liability protection with flexible tax treatment. An LLC is a state-law structure, meaning you form it at the state level, but your federal tax responsibilities depend on the tax election you make with the IRS.

Pro Tip: Consult the IRS business structures page and the U.S. Small Business Administration (SBA) resources before filing anything. Both are free and give you jurisdiction-specific guidance that saves time and money.

How to register your company in the U.S.: step by step

Typical U.S. business registration follows a staged sequence: choose a structure, obtain an EIN, then complete state registration and licensing. Treating this as a checklist prevents the most common procedural mistakes. Skipping steps or reversing the order creates delays and sometimes requires refiling.

Here is the full sequence:

1. Choose your business structure. This decision shapes every form you file after it. Refer to IRS guidance and confirm your choice before moving forward.
2. Select and verify your business name. Each state has a name availability database. Check it before committing to a name, since duplicates are rejected.
3. Appoint a registered agent. Every U.S. LLC and corporation requires a registered agent with a physical address in the state of formation. This person or service receives legal documents on your behalf.
4. File your formation documents. For an LLC, this is the Articles of Organization. For a corporation, it is the Articles of Incorporation. File these with the Secretary of State in your chosen state. Learn more about the Secretary of State’s role in this process.
5. Apply for an Employer Identification Number (EIN). The EIN is your federal tax ID. The IRS issues it free of charge. You need it to open a U.S. bank account, hire employees, and file federal taxes.
6. Complete state-specific licenses and permits. Requirements vary by state, industry, and city. Some businesses need multiple licenses at the local, state, and federal levels.
7. Set up your operating agreement or corporate bylaws. This internal document governs how your business runs. It is legally required in some states and strongly recommended in all others.

State portals vary widely in their tools and speed. Nevada’s SilverFlume portal consolidates entity formation, business license applications, and compliance renewals into one system. That integration cuts the time you spend switching between agencies. Hawaii’s Business Registration Division offers both online and paper filing options, giving you flexibility based on your situation. Montana’s Business Filing Portal provides 24/7 electronic access to business documents and new registrations. Utah’s Department of Commerce requires you to select your entity type before form fields appear, so prepare your information in advance.

Pro Tip: When possible, choose a state with a consolidated portal like Nevada’s SilverFlume. It reduces back-and-forth between agencies and keeps your formation and compliance filings in one place.

U.S. vs. UK company formation: key differences

The U.S. and UK both offer well-established paths for business registration, but the systems work very differently. Understanding those differences helps you choose the right jurisdiction for your goals.

In the U.S., formation is handled at the state level. Each of the 50 states has its own fees, timelines, and filing requirements. There is no single federal registration portal for business entities. This decentralized system gives you flexibility in choosing a favorable state, but it also means you need to research each state’s rules separately. For non-residents, states like Delaware, Wyoming, and Nevada are popular because of their business-friendly laws and low fees.

In the UK, all companies register through Companies House, a single centralized government body. This makes the process more uniform. You file once, and your company is recognized across the entire country. The UK also requires ongoing filings called confirmation statements, which confirm your company’s details are current.

UK Companies House increased online incorporation fees from £50 to £100 starting february 1, 2026. This change reflects costs tied to the Economic Crime and Corporate Transparency Act (ECCTA). The fee increase also affects confirmation statement filings. For entrepreneurs comparing jurisdictions, this is a meaningful cost shift to factor into your planning.

The UK’s centralized model is faster for initial registration. The U.S. model offers more flexibility in structure and tax planning, especially for non-residents who want to operate globally through a U.S. entity. For a detailed breakdown of what non-residents need to know about U.S. business formation, the requirements differ from domestic filings in important ways.

Post-formation compliance: what you must do after registering

Company formation is just the start. Tax IDs like the EIN and licensing come next and often vary by jurisdiction. Missing these steps puts your company at risk of penalties, loss of good standing, or forced dissolution.

Experienced founders plan for annual reports, licenses, and certificates of existence at formation time, not after the fact. Building compliance into your calendar from day one prevents surprises. Here are the core ongoing requirements to track:

• Annual reports or biennial reports. Most U.S. states require these to keep your entity in good standing. Deadlines and fees vary by state.
• Confirmation statements (UK). UK companies must file a confirmation statement at least once every 12 months through Companies House.
• EIN-related federal tax filings. Even if your LLC has no income, the IRS may require a return depending on your tax election. Non-residents with U.S. LLCs often need to file Form 5472 and Form 1120.
• Business licenses and permits. Many licenses expire annually. Track renewal dates for every license at the city, county, and state level.
• Registered agent maintenance. Your registered agent must remain active and reachable. If they resign or become unavailable, you must appoint a replacement immediately.
• Operating agreement updates. When ownership or management changes, update your operating agreement and notify your state if required.

Consolidated portals like Nevada’s SilverFlume reduce friction by integrating entity formation with license renewals and ongoing compliance in one place. Hawaii’s BREG portal offers similar functionality for Hawaii-based entities. Using these tools keeps your compliance calendar organized and reduces the risk of missed deadlines. For non-residents managing state filing requirements, the obligations are the same as for domestic owners, but the logistics require more planning.

Key Takeaways

Choosing the right business structure before filing is the single most important decision in any company formation, because it determines every tax and legal obligation that follows.

What I have learned from watching entrepreneurs get formation wrong

Most formation mistakes happen before anyone files a single document. Entrepreneurs pick a structure based on what a friend used or what sounds familiar, without checking how it affects their specific tax situation. An LLC is the right choice for most small businesses, but not for everyone. A C corporation makes sense if you plan to raise venture capital. An S corporation has restrictions on who can be a shareholder. These distinctions matter, and getting them wrong costs real money to fix.

The second most common mistake is treating formation as a one-time event. I have seen founders file their Articles of Organization, get their EIN, and then go silent on compliance for two or three years. Then they discover their company has been administratively dissolved by the state for missing annual report filings. Reinstatement is possible, but it costs more time and money than staying current ever would have.

State portal tools like Nevada’s SilverFlume genuinely help. They are not just a convenience. They reduce the chance of missing a renewal because everything is visible in one dashboard. If your state offers a consolidated portal, use it from the start and set calendar reminders for every deadline it shows.

One more thing: non-residents often underestimate how much the registered agent role matters. Your registered agent is your legal point of contact in the state. If they miss a service of process notice, you may not find out until a default judgment has been entered against your company. Choose a professional registered agent service, not a friend’s address.

The entrepreneurs who get formation right treat it as a system, not a task. They document every step, track every deadline, and build compliance into their business operations from day one. That approach keeps their company in good standing and lets them focus on growth instead of paperwork.
