US business registration is not one universal filing. Your requirements depend on your entity, location, business name, tax obligations, industry, and the states where you conduct business.

Key Takeaways

  • Forming an LLC or corporation, registering a DBA, obtaining an EIN, and securing licenses are separate steps.
  • Most LLCs and corporations form through a state filing office, not a single federal business registry.
  • Your entity choice affects personal liability, taxation, ownership, management, and fundraising.
  • Forming outside your operating state may require an additional foreign qualification.
  • You can complete routine filings yourself, but complicated ownership, tax, or multistate plans may require professional advice.
  • Use official state records to check a company's registration and current status.

What US Business Registration Actually Includes

Business registration in the US can refer to several legally distinct tasks. Understanding these layers prevents you from assuming that one filing makes your business compliant everywhere.

  • Entity formation: An LLC or corporation normally becomes a legal entity after its formation document is accepted by the appropriate state office. A sole proprietorship generally does not require an entity formation filing.
  • Business name registration: A state filing approves an entity name for that state's records. A sole proprietor or entity using another public-facing name may also need a fictitious name, assumed name, or doing-business-as filing.
  • Tax registration: The IRS issues Employer Identification Numbers for federal tax administration. State revenue and labor agencies may require separate accounts for sales tax, payroll, unemployment, or other obligations.
  • Licenses and permits: Federal, state, county, and city agencies regulate certain industries, professions, locations, and activities. Entity formation does not replace these approvals.
  • Trademark protection: State approval of a company name does not automatically create nationwide trademark rights. Federal trademark registration is a separate process through the U.S. Patent and Trademark Office.

There is therefore no single US business registration form, certificate, office, or database. The responsible agency and resulting document depend on what you are registering. Before filing, list every state and locality where you will operate, hire employees, maintain premises, or conduct regulated work.

Company Registration Process in the USA

The company registration process starts with your business plan, not with a generic online form. Complete the steps in an order that avoids filing under the wrong name, in the wrong state, or as an unsuitable entity.

  1. Choose an entity. Compare a sole proprietorship, partnership, LLC, and corporation based on ownership, liability, taxes, governance, and financing plans.
  2. Select the formation state. For many small businesses, this is the state where the owner works and the company conducts its principal operations.
  3. Check the name. Search the official state business registry and review naming rules. Conduct a separate trademark review before investing in branding.
  4. Appoint a registered agent. State-formed entities generally designate an agent with a physical address in the formation state to receive official documents.
  5. File formation documents. An LLC typically files articles of organization or a similarly named document. A corporation typically files articles or a certificate of incorporation. Terminology varies by state.
  6. Prepare governing documents. Create an LLC operating agreement, corporate bylaws, ownership records, and any founder or shareholder agreements your company needs.
  7. Complete tax and licensing registrations. Determine whether you need an EIN, state tax accounts, employer registrations, or federal, state, and local licenses.

Fees, processing options, and required information differ by jurisdiction. Review the current instructions from the official filing agency before submitting anything. For a closer look at expected expenses, see how much it costs to register a company in the U.S.

Choosing an Entity for Company Formation in the USA

Your structure affects who owns the company, how it is managed, the owners' exposure to business obligations, and its federal tax treatment. Review the main types of companies in the USA before paying a formation fee.

Structure Formation Filing Liability Treatment Ownership and Tax Considerations
Sole proprietorship Usually no state entity filing, although DBA, tax, and license filings may apply No legal separation between the owner and business One individual owner; business activity is generally reported by the owner
LLC State formation document Generally separates members from company liabilities when properly maintained Flexible ownership and management; federal tax classification depends on elections and number of owners
C corporation State incorporation document Corporation is legally separate from shareholders Owned by shareholders; the corporation is a separate federal taxpayer
S corporation Formation of an eligible state entity followed by a federal tax election Depends on the underlying corporation or eligible LLC Subject to federal shareholder and stock restrictions, including restrictions involving nonresident alien shareholders

An S corporation is a federal tax status, not a stand-alone state entity type. A business first forms an eligible corporation or LLC and then makes the applicable tax election. An LLC may offer flexible management, while a C corporation is often considered when a company expects institutional investment or multiple classes of stock. Tax outcomes depend on the facts, so coordinate entity selection with a qualified tax adviser. Founders specifically considering an LLC can review the LLC registration steps and requirements.

Choosing a State, Name, and Registered Agent

Your operating state is often the practical place for company setup. Forming in another state does not necessarily avoid your home state's filing obligations, taxes, licenses, or reporting rules. If your company conducts business in a state other than its formation state, that second state may require foreign qualification.

Compare states using factors tied to your actual plan: where the owners and employees work, where the company has an office, where customers receive regulated services, state taxes, annual reports, filing fees, investor expectations, and governing law. Do not choose a state solely because it is commonly promoted as business-friendly. Paying for formation in one state and foreign qualification in another can create two sets of fees and compliance duties.

Before company registration, search the official registry for your proposed legal name. A name being available does not mean it is free of trademark risk. Search relevant federal trademark records and consider similar spellings, sounds, products, and services. If you will trade under a different name, check the state, county, or city rules for an assumed-name or DBA filing.

An LLC or corporation generally needs a registered agent in each state where it forms or qualifies. The agent receives lawsuits and official government communications at a physical address in that state. An owner may be able to serve if state requirements are met, but availability, privacy, and reliable document handling should guide the decision.

EINs, Tax Accounts, Licenses, and Banking

An EIN is a federal tax identification number issued by the IRS. It is not proof that an LLC or corporation exists under state law, and it is not interchangeable with a state filing number. Businesses commonly use an EIN for federal tax filings, payroll, and financial accounts. Check the IRS EIN instructions to determine whether you need one and which application method applies. You can also review how to register a business with the IRS.

Your state may assign its own entity identification number when accepting a formation filing. Revenue, labor, and licensing agencies can issue additional account or permit numbers. Keep each identifier labeled by its issuing agency and purpose. Searching for a single US business registration number can lead to the wrong record because the United States does not assign one universal number covering every registration.

Licenses depend on your location and activity. A city may require a general business license, while a state board may regulate professional services. Federal agencies oversee certain regulated industries. The SBA licenses and permits guide can help you identify agencies, but you should confirm current requirements directly with each issuing authority.

After formation, consider opening a dedicated business bank account. Banks set their own documentation requirements, which may include formation records, an EIN, ownership information, identification, and governing documents. A separate account improves recordkeeping and helps prevent personal and business transactions from becoming mixed.

How to Check US Company Registration Details

Use the official business registry maintained by the state where the entity formed or qualified. Most state registries provide a free online search by entity name, and some also allow searches by an assigned filing number. There is no comprehensive federal database showing every active US sole proprietorship, LLC, corporation, DBA, and local license.

When reviewing a result, confirm more than the name. Check the entity type, jurisdiction, formation or registration date, status, principal information made public by the state, and filing number. Similar company names can belong to unrelated businesses. A record marked active or in good standing generally reflects the state's records, but it does not establish that the company holds every required license, has paid every tax, owns its brand, or is financially sound.

A basic search result may not be the same as an official business registration certificate. Depending on the state and purpose, the relevant document might be accepted articles, a certificate of formation, a certificate of incorporation, a certificate of status, or a certified copy. Banks, investors, vendors, and foreign authorities may request different documents.

If you need formal evidence, order it through the official state registry rather than relying on a screenshot or third-party directory. Check the document's date, entity name, and status before using it for a transaction. For state-specific differences, New York founders can review the separate guide to business registration in New York State.

If your formation plan involves multiple owners, investors, a non-US founder, customized governance, or operations in several states, you can post your legal need on UpCounsel's marketplace. Responses typically arrive within a day. An attorney can assess the entity and state choices, prepare or review governing documents, identify registrations and licenses, and coordinate tax questions with the appropriate adviser.

Nonresident and Multistate Company Setup

A nonresident can generally own a US LLC or C corporation, but ownership does not authorize the person to work in the United States. Immigration status and work authorization are separate from company formation. If you plan to perform services while physically present in the country, review the appropriate visa and work rules rather than relying on your ownership interest.

Nonresident founders should address five issues early. First, choose an entity after considering US and home-country tax treatment. Second, retain a registered agent that satisfies the formation state's requirements. Third, follow the IRS procedures available to international applicants when obtaining an EIN. Fourth, ask prospective banks what identity, address, ownership, and in-person verification documents they require. Fifth, identify every state where the business's activities may create registration, tax, employment, or licensing obligations.

S corporation status is generally unavailable when the entity has a nonresident alien shareholder. An LLC or C corporation may therefore be more relevant, but neither is automatically the best tax choice. A foreign company may also be able to own a US entity, subject to entity, tax, reporting, banking, and industry-specific restrictions.

A domestic entity is one operating under the law of its formation state. The same entity is considered foreign when registering in another US state. For example, an entity formed in one state may need authority to conduct business in a second state. Foreign qualification does not create a new company, but it can add a registered agent, reports, fees, taxes, and local compliance duties. Check each state's current standard for activities that require registration.

Registering a Company Yourself and Staying Compliant

You can usually handle a routine company set up yourself by using official state, IRS, and local agency instructions. A formation service or lawyer is not automatically required. Filing directly also lets you see the actual government fee and avoids mistaking a private service's website for an official registry.

A do-it-yourself filing works best when the ownership is simple, the owners agree on management and economics, the company will operate in one state, and the business is not heavily regulated. Read every instruction before filing. Use consistent legal names and addresses, save accepted documents, and record each confirmation number. Do not treat a template operating agreement or bylaws as a substitute for discussing ownership rights, voting, transfers, departures, intellectual property, or deadlocks.

Registration is the beginning of compliance, not the end. Create a calendar for annual or periodic state reports, franchise or entity taxes, license renewals, registered-agent updates, tax returns, and ownership or address changes. Requirements and deadlines vary by agency and jurisdiction, so rely on current official notices.

Keep formation records, tax letters, licenses, governing documents, ownership records, and major approvals in a secure company file. Review your registrations before entering a new state, hiring employees, moving offices, changing the business name, adding an owner, or launching a regulated product. Those events can trigger filings that were not required during the original company formation.

Frequently Asked Questions

How Do I Do Business in America?

You can do business in America by determining where and how you will operate, then completing the registrations tied to those activities. A foreign seller may not always need a new US entity, but contracts, taxes, import rules, regulated activities, employees, and physical operations can create separate obligations. Obtain legal and tax advice before committing to a structure.

Can I Set Up a Limited Company on My Own?

Yes, you can generally set up an LLC or corporation yourself through the appropriate state filing office. The United States does not use "limited company" as one uniform nationwide entity classification. Identify the state entity you intend to create, follow that state's instructions, and get advice if ownership rights, investment terms, or tax elections require customized planning.

How Can I Open a Company in the USA?

You can open a company in the USA by selecting a state and entity, appointing a registered agent, and submitting the state's formation document. Approval creates the entity, but opening for business may require additional tax accounts, insurance, banking arrangements, contracts, and premises approvals. Build those operational items into your launch schedule rather than waiting for the state filing.

How Do I Create an LLC in Texas?

You create a Texas LLC by checking the name, designating a qualifying registered agent, and filing the required formation document with the Texas Secretary of State. After acceptance, address the operating agreement, tax registrations, licenses, and ongoing state obligations. Use current Texas government instructions because required information, fees, and submission methods can change.

Is Getting an LLC the Same as Registering a Business?

No, getting an LLC is only one type of business registration. The LLC filing creates a state-law entity, while DBA filings, tax accounts, professional approvals, local permits, and trademark applications serve different purposes. A business may need several of these, and some sole proprietors register names or obtain licenses without forming an LLC.

How Can I Check if a Business Is Registered?

You can check a business by searching the official registry in the state where it claims to be formed or authorized. If you cannot find it, try its exact legal name, prior names, or state filing number. Also confirm that you searched the correct state, since a local trade name or out-of-state entity may not appear in the database you first selected.
