Essential concepts
An LLC (Limited Liability Company) is a U.S. business structure that combines limited liability protection with administrative and tax flexibility. For foreign entrepreneurs, it can be useful for operating in dollars, receiving international payments, and separating business activity from personal finances. Tax treatment depends on the number of members, activity, owners’ tax residence, and whether there is income connected with the United States.
The EIN (Employer Identification Number) is the company’s tax identification number issued by the IRS. It is used to identify the LLC with banks, payment platforms, suppliers, tax filings, and corporate procedures. It is usually requested after the company is formed.
The ITIN (Individual Taxpayer Identification Number) is a personal tax number issued by the IRS for people who need to comply with U.S. tax obligations and are not eligible for an SSN. It does not authorize work, does not grant immigration status, and does not replace a visa or residency.
A Registered Agent is the person or company authorized to receive official notices, legal documents, and state communications on behalf of the LLC. It is required to maintain a company registered in most states.
The Operating Agreement is the internal agreement of the LLC. It defines management rules, member participation, profit distribution, responsibilities, and general operation. Even when it is not filed with the state, it is very important for banks, partners, and internal organization.
An Annual Report is a state requirement that some jurisdictions use to keep the company active and updated. It may include a state fee and basic LLC information. It should not be confused with the federal tax return.
