How to Register a Company in the US 2026: C-Corp Incorporation Guide

TKEG Expat · Updated 2026

Introduction

The United States remains one of the most attractive destinations for business owners looking to establish a legal entity with global credibility. Whether you are a domestic entrepreneur or a foreign national, understanding how to register a company in the US — specifically a C Corporation (C-Corp) — is essential to making informed business decisions. The US offers a stable legal framework, access to capital markets, and strong protections for personal assets, making it the preferred choice for founders who want to protect your business while scaling internationally.

A C-Corp is a distinct business structure recognized at both the federal and state level. Unlike a limited liability company (LLC), a C-Corp can issue multiple classes of stock, making it ideal for venture-backed startups and companies planning to go public. Choosing the right business entity is a critical first step — depending on your business goals, a C-Corp may offer advantages in fundraising, credibility, and long-term tax planning.

How to Register a Company in the US: Choosing a State

Once you understand the requirements, the next step is deciding which state to incorporate in. The United States has 50 states, each with its own corporate law, tax policy, and registration fees. For most foreign entrepreneurs, the most popular states for incorporation include Delaware, Wyoming, and Nevada. Delaware is known for its mature corporate law framework and flexible management provisions, making it the top choice for most venture-backed startups. Wyoming stands out for its low registration costs and zero state corporate income tax, making it attractive for small businesses with limited budgets.

When choosing a state of incorporation, consider the following factors: the state corporate income tax rate, annual report filing fees, registered agent service availability, and the state’s requirements for foreign shareholders and directors. TKEG Expat can help you select the most suitable state based on your business goals and financial planning, ensuring the entire registration process is efficient and compliant.

Before you choose a business structure, it is important to understand how you will pay taxes. US C-Corps are subject to a 21% federal corporate income tax, and may also face state-level taxes depending on where the company is registered. There is no federal value-added tax (VAT) in the United States. Non-residents must pay 30% withholding tax on dividends, interest, and royalties, though this may be reduced by tax treaties. Understanding these financial obligations is essential for managing your US company effectively.

Frequently Asked Questions

Can foreigners register a company in the US?

Yes. Non-US residents can form a C-Corp without a visa or green card. You will need to appoint a registered agent in the state of incorporation and obtain an Employer Identification Number (EIN) from the IRS. There is no requirement for directors or shareholders to be US citizens.

How many shareholders does a US C-Corp need?

A C-Corp requires a minimum of one shareholder. There is no maximum limit, and shareholders can be individuals, other corporations, or foreign entities. This flexibility makes C-Corps a popular choice among business owners seeking outside investment.

What is the difference between an LLC and a C-Corp?

A limited liability company (LLC) offers pass-through taxation and simpler administration, while a C-Corp is taxed at the corporate level and can issue stock to investors. Both protect your personal assets from business liabilities. A C-Corp is generally preferred if you plan to raise venture capital or register trademarks through the US Patent and Trademark Office under the corporate name. Choosing the right business entity depends on your goals, investor expectations, and how you want to pay taxes.

Is there a minimum capital requirement to incorporate?

No. There is no minimum paid-up capital required to form a C-Corp in the US. The Articles of Incorporation will state the number of authorized shares, but there is no obligation to fund them at incorporation. This makes it accessible for startups and foreign business owners launching a new venture.

What annual obligations does a US C-Corp have?

After incorporation, a C-Corp must file an Annual Report with the state of registration and pay the associated fee. The company must also file federal and state income tax returns on time, maintain a registered agent, and keep corporate records up to date. Failure to meet annual filing requirements can result in administrative dissolution. TKEG Expat provides comprehensive annual compliance management to keep your US company in good standing.

How long does it take to register a US C-Corp?

Processing times vary by state. In general, it takes 1 to 4 weeks from filing the Articles of Incorporation to receiving the Certificate of Incorporation. Some states offer expedited processing that can be completed within a few business days. TKEG Expat will help you choose the most suitable state for your business needs and manage the entire process.
