US Business Formation for Non-Residents: A Complete Guide

The United States remains the premier destination for global business scaling, offering foreign founders access to a massive, high-purchasing-power market, a stable legal system, and international prestige. The US corporate landscape allows non-residents to incorporate and manage a company completely remotely from anywhere in the world.

In this guide, we break down the entire lifecycle of a company: from selecting the right legal structure to navigating annual tax compliance procedures.

Checklist: How to Open a Company in the US

Here is the step-by-step roadmap for anyone looking to start a business in the US:

1. Choose a company type (LLC or C-Corp).
2. Select a state of incorporation.
3. Check availability and reserve the company name.
4. Secure a Registered Agent (Legal Address).
5. File formation documents and pay state fees.
6. Receive official state approval documents.
7. Draft internal corporate documents.
8. File an application for an Employer Identification Number (EIN).
9. Receive the official EIN confirmation letter.
10. Optimize tax classification (Optional for LLCs).
11. Set up a dedicated business mailing address.
12. Open a corporate business bank account.
13. Launch commercial business operations.

Step 1: Which Company Types Can a Non-Resident Open?

A foreign entrepreneur (without US residency status) incorporating a business remotely can choose between two primary legal structures:

• Limited Liability Company (LLC): A hybrid structure that protects your personal assets (like a corporation) while offering immense flexibility in management and profit distribution (like a partnership). By default, a single-member LLC owned by a non-resident is treated by the IRS as a disregarded entity(a tax-transparent pass-through structure).
• C-Corporation (C-Corp):A standalone legal entity owned by shareholders. A C-Corp is completely separate from its owners, is taxed at a fixed federal corporate income tax rate of 21%, and is the only viable option if you plan to raise venture capital or issue stock options.

Important: The popular S-Corporation (S-Corp) tax election is entirely unavailable to non-resident aliens (individuals filing Form 1040NR).

Step 2: Choose a State of Incorporation

Since you do not have a physical office in the US, you can choose any state you prefer. Remote entrepreneurs frequently select the following jurisdictions:

• Wyoming (WY): Ideal for small businesses. There is no state income tax, annual renewal fees are minimal (around $60), and it offers high asset privacy.
• Delaware (DE): The golden standard for tech startups. The state features a dedicated business court system (Court of Chancery), and global investors universally trust this jurisdiction.
• Texas (TX): A powerful economic hub where the franchise tax is effectively zero until gross revenue exceeds $2.47 million per year. Note that registering for a Sales Tax Certificateis required if selling applicable goods.

Conduct a search on the official online portal of the Secretary of State in your chosen state to ensure your desired name is available. An LLC name must include the designator "LLC", and a corporation name must include "Inc." or "Corp." At this stage, it is also highly recommended to check domain name (URL) availability and perform a trademark search in the USPTO database.

Step 3: Check Availability and Reserve the Company Name 

Conduct a search on the official online portal of the Secretary of State in your chosen state to ensure your desired name is available. An LLC name must explicitly include the abbreviation "LLC", while a corporation name must include "Inc" or "Corp". Additionally, check domain name (URL) availability and verify the existence of conflicting trademarks in the USPTO database.

Step 4: Secure a Registered Agent

State laws require every company to maintain an official Registered Agent physically located within the state of incorporation. The agent must be available at their registered office during standard business hours to accept official government correspondence, legal notices, and IRS letters. You should complete this step once you know the name is free, as you will list the agent's address during state filing.

Step 5: File Formation Documents and Pay State Fees

Submit your official registration paperwork to the Secretary of State's office. In almost all states, this process is now handled entirely electronically via local state portals.

The name of the filing form depends directly on your chosen entity structure:

• For an LLC, you will file Articles of Organization or a Certificate of Formation.
• For a Corporation, you will file Articles of Incorporation.

The state's mandatory filing fee is paid during this step. Fees vary significantly: states like Arkansas, Colorado, Hawaii, Iowa, and Mississippi charge only about $50–$53, whereas Texas charges $300.

Critical Address Protocol:

When filling out the state registration form, the system will prompt you for your company's addresses. At this point, as a non-resident, you do not yet have a dedicated US office or business mailing address. Therefore, it is a completely legal and standard industry practice to use your Registered Agent's address for all three mandatory address fields:

1. Registered Agent Address.
2. Principal Business Address.
3. Mailing Address.

Step 6: Receive Official State Approval Documents

Once processed, the Secretary of State will issue your approved formation documents bearing the state's official filing stamp (Articles of Organization for LLCs or Articles of Incorporation for corporations). This document serves as the birth certificate of your business.

Filing timelines depend heavily on the state and current register volume. Notable state traits:

• Delaware (DE): Offers highly flexible. Expedited Filing options for an additional fee, allowing processing within 1 day or even 1 hour.
• Texas (TX): Operates under its unique online portal, SOSDirect. To use it, you must register an account and link a credit card upfront. Keep in mind that every single basic interaction—including checking name availability—in the Texas registry costs a mandatory fee of at least $1 per query.

Step 7: Draft Internal Corporate Documents

Even if you are the sole owner of the business, you must establish a clear legal and financial separation between yourself as an individual and your corporate entity. To achieve this, you need to draft the following internal documents:

• For an LLC, an Operating Agreementis drafted—this internal document details the ownership percentages (%), profit distribution rules, and management structure of the company.PDF
• For a C-Corp, corporate Bylaws are adopted, along with organizational resolutions confirming the appointment of the Board of Directors and share issuance terms.

These documents are never filed with the state; they are kept securely in corporate records. However, they are strictly mandatory when opening commercial US bank accounts to prove director authority and corporate governance.

Special Structuring for Immigration Cases (O-1 Visas and EB-1 Petitions)

If a US company is being formed with the intent of sponsoring a future O-1 extraordinary ability visa or an EB-1A/EB-1C immigrant petition, a standard "sole owner/sole director" approach can trigger an immediate denial from the US Citizenship and Immigration Services (USCIS).

Under USCIS precedents, a fundamental visa requirement for employment-based categories is establishing a valid Employer-Employee Relationship. The agency must see that the petitioning US company has the legal right to control your work, hire you, pay your salary, and fire you if necessary. If you are the 100% owner and sole officer of the company, USCIS often rules that you cannot be "employed" by yourself, as no independent corporate body exists to oversee your role.

How to Properly Structure the Entity for O-1 and EB-1 Frameworks:

• For a C-Corporation: You can maintain majority stock ownership, but you must establish an independent Board of Directors during incorporation. The corporate Bylawsmust explicitly vest the Board with the exclusive authority to hire, oversee, compensate, and terminate the Chief Executive Officer (CEO/President).
• For an LLC: Since a pass-through entity structure does not inherently utilize a standard corporate hierarchy, your Operating Agreement must state that the company is Manager-Managed (rather than Member-Managed). You then form a Board of Managers (serving as a Board of Directors) that holds the corporate power to enter into an official Employment Agreementwith you as an executive.

Pro Tip: All employment conditions, corporate duties, salary metrics, and the independent Board's right to control your position must be formally executed in internal company documents prior to signing the employment contract or filing petitions with USCIS.

Step 8: File an Application for an EIN

Your next essential step is obtaining an Employer Identification Number (EIN). This is a unique, nine-digit corporate tax ID issued by the Internal Revenue Service (IRS) that acts as an IRS business registration number.

Because foreign non-resident founders do not possess a US SSN or ITIN, the automated online application on the IRS portal is completely unavailable. Non-residents must file manually by preparing Form SS-4 (Application for Employer Identification Number) and submitting it to the IRS international unit via one of these avenues:

• By Fax: Send Form SS-4 to the dedicated IRS international fax line. Fax lines operate 24/7, and processing typically takes 1 to 3 weeks.
• By Mail: Send the documents to: Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999. Using a tracked international mailing service is strongly recommended. Due to logistics, processing takes between 4 to 8 weeks.
• By Phone: Calling the IRS international line to dictate the form verbally is an option exclusively reserved for Sole Proprietors. This method cannot be legally used for Corporations or LLCs.

Any typos or choosing an incorrect tax classification box on Form SS-4 will result in the IRS returning or rejecting the form, wasting months of development time. At Regizy, we manage this complex process completely. Our team operates as your authorized Third Party Designee to ensure quick, flawless execution.

Step 9: Receive the Official EIN Confirmation Letter

Once processed, the IRS will issue your official EIN confirmation letter (Form CP 575). The physical document will be mailed to your Registered Agent's address or your specified corporate mailing address.

Step 10: Optimize Tax Classification (Optional Pass-Through to Corporate Shift)

By default, a single-member LLC owned by a non-resident is designated by the IRS as a Disregarded Entity. This means the company is tax-transparent on a federal level; the entity pays no tax itself, and all profits or losses pass directly onto the owner's personal tax profile.

However, pass-through taxation presents a severe operational bottleneck for foreigners. To file an annual return under a disregarded entity structure, a non-resident owner is legally required to obtain an Individual Taxpayer Identification Number (ITIN) from the IRS. Getting an ITIN is a tedious process requiring you to mail your original passport to Austin, TX, or physically visit a Certifying Acceptance Agent (CAA), and takes months to process.

To simplify corporate administration, US tax law allows you to change your LLC's tax status to a C-Corporation (C-Corp) by filing federal Form 8832 (Entity Classification Election). Once elected, the LLC is taxed as an independent corporation, filing its own return and paying a flat federal corporate income tax rate of 21%.

Mechanism and Strict Filing Timelines:

• The 75-Day Rule: Form 8832 must be physically received and stamped by the IRS within exactly 75 daysof the company's official date of formation (or within 75 days of the targeted effective date).PDF
• Missed Deadline Consequences:If you miss this 75-day window, the IRS will lock your entity into its default disregarded pass-through status for the current tax year. You will have to wait until the next fiscal year to re-apply.

Why Regizy Experts Recommend This Step:

1. Eliminates the ITIN Bottleneck: A corporate tax structure files its own annual return via Form 1120 using only the company's EIN. As the foreign owner, you are no longer required to get an ITIN simply to submit your business's annual federal filings.
2. Streamlined Corporate Compliance: Transitioning to a corporate tax profile removes the need for complex, personal international cross-border income declarations for non-resident individuals. Your business complies via standard corporate bookkeeping, reducing overall accounting overhead.
3. Perfect for Remote Scaling: If you operate completely remotely and want your digital payment processing and merchant gateways fully operational as quickly as possible without international data hurdles, electing C-Corp status via Form 8832 avoids subsequent IRS auditing headaches.

Step 11: Set Up a Dedicated Business Mailing Address

After receiving your EIN and before approaching banks, you must complete a crucial compliance separation step—separating your Registered Agent's office from your actual business mailing address. We highly recommend that every non-resident founder rent a commercial Virtual Office or activate a verified Digital Mailbox service inside the United States.

It is important to understand the regulatory differences between these address classifications:

1. Registered Agent Address:The statutory legal address used exclusively for accepting formal service of process and state corporate notices.
2. Principal Place of Business (Business Address): The physical headquarters location where the company's operational and management decisions take place.
3. Mailing Address: The operational address where standard correspondence, bank debit cards, corporate checks, and client letters are sent.

Why Banks Reject Registration Addresses:

Under strict Know Your Customer (KYC) rules mandated by the USA PATRIOT Act, risk compliance systems at US banks and business fintech platforms maintain automated blocklists of addresses belonging to mass-volume corporate incorporation agents. If you attempt to open a corporate account using your Registered Agent's address for your Business Address or Mailing Address, the bank's system flags your company as an anonymous "shell company" lacking a substantive economic footprint in the US. This triggers an immediate application freeze or a hard denial.

Step 12: Open a Corporate Business Bank Account

Once your state Articles, Operating Agreement, and official IRS EIN letter are ready, you can apply for an account. Traditional US banking groups require the managing director to appear physically at a branch for identification under USA PATRIOT Act rules. However, international founders can successfully secure robust corporate accounts entirely online via leading US business fintech platforms (such as Mercury or Wise).

Step 13: Launch Commercial Operations

Your corporate framework is now fully set up, compliant, and ready to capture payments, execute commercial contracts, and scale legally in the global marketplace.

Post-Formation Requirements

Additional Business Licensing

Depending on your commercial vertical and state laws, your business may require:

• Sales Tax Certificate: If you sell physical items or specific digital services to US consumers, you must register with your state's Department of Revenue to collect and remit sales tax.
• Industry Permits: Specialized activities (e.g., e-commerce fulfillment marketplaces, global logistics, cross-border corporate consulting) may require specific municipal or state-level administrative licenses.

Annual Mandatory Compliance

To keep your entity in Good Standing and prevent the state from executing an administrative dissolution, your company must meet four yearly compliance items:

1. Filing an Annual Report: Most states require an annual informational filing to confirm the company is operational and update corporate records. The state levies a flat filing fee for this document. Failing to file on time triggers steep penalty assessments and forces the state to dissolve your business.
2. Maintaining a Registered Agent: Your state-level registered office fee must be renewed annually. If you lose your Registered Agent, the state revokes your legal corporate standing immediately.
3. Paying State Franchise Tax: A mandatory state tax levied for the privilege of holding a registered corporate entity within that jurisdiction. California charges a steep minimum franchise tax of $800 per year even if your business is pre-revenue or runs at a loss. Wyoming, by contrast, charges an asset-based fee that averages just $60 for small businesses.
4. Filing a Federal Tax Return with the IRS: Every US business formed by a non-resident must file federal documentation with the IRS annually, even if the company had zero economic transactions and holds a completely net-zero balance sheet. Your reporting framework depends entirely on your entity's tax structure:Scenario A: If Structured as a Corporation (C-Corp): The business acts as an independent tax entity and must file an annual corporate return via Form 1120. The business calculates and pays its flat 21% federal tax rate directly from net corporate profits. Key benefit:Form 1120 only requires the company's EIN; the individual foreign owner does not need to secure an ITIN.Scenario B: If Structured as a Single-Member LLC: The foreign non-resident owner is legally required to submit an informational return via Form 5472 attached to a pro-forma Form 1120. Critical ITIN Warning: Because your LLC operates under default pass-through metrics (Disregarded Entity), the financial profits legally pass directly onto you as an individual. Therefore, you are strictly required to obtain an individual ITIN to process your US tax profile and balance sheet distribution declarations properly.Severe Non-Compliance Penalties: The penalty for failing to file, filing late, or submitting incomplete data on Form 5472 is completely automated and non-negotiable. The IRS issues a mandatory $25,000 fine for every single missed tax year.

CPA Tips

• Analyze Your Effectively Connected Income (ECI) Status: If your business is an LLC but you manage its operations entirely from outside the borders of the US, and you possess no US-based personnel, storefronts, or fulfillment warehouses, your commercial revenue may not be classified as Effectively Connected Income (ECI). If your income is non-ECI, you may be entirely exempt from US federal income tax assessments. Always consult an expert CPA to thoroughly review your operational workflow.
• Enforce Strict Corporate Veil Separation: Never mix personal funds with your corporate capital bank balances. Paying for personal items out of your US business accounts destroys your corporate veil protection, leaving you personally liable for corporate debts or lawsuits.
• Pre-Revenue Status Does Not Exempt You From Filings: The most common mistake international owners make is assuming that because their business made $0 in profit or owes $0 in taxes, they do not need to file paperwork. Form 5472 compliance is strictly mandatory for foreign-owned LLCs. Missing your filing date ensures a flat $25,000 fine from the IRS.
