Documents and Forms You May Encounter

For entrepreneurs who want to establish a company in America, the process is not limited to just filling out an application form. Many technical documents and systems are encountered, such as tax identification numbers, state documents, sales tax permits, and e-commerce integrations. In this article, we cover the most frequently encountered documents when starting a company in America and what they are used for with brief explanations.

W-7 Form - For ITIN Application

The W-7 Form is the official IRS form used by individuals who cannot obtain a Social Security Number (SSN) to apply for an ITIN (Individual Taxpayer Identification Number) to be included in the US tax system. It is a critical step especially for foreign investors and entrepreneurs.

SS-4 Form - For EIN Application

The SS-4 Form is the application form submitted to the IRS by individuals or organizations establishing a company in America to obtain an EIN (Employer Identification Number). EIN is required for the company's tax transactions, bank account opening, and legal activities.

Single-Member LLC and "Disregarded Entity" Note

Single-member LLCs are generally treated as a "disregarded entity" for federal income tax purposes by default; meaning company profit/loss "flows" to the owner's return. There is no separate IRS form called "disregarded entity notification" for this default classification.

If you want to change tax classification

• Form 8832: To elect taxation like a "corporation" for the LLC (Entity Classification Election)
• Form 2553: For S-Corporation election if eligibility is met

Note: Additional filing obligations may arise in some structures with foreign partners. CPA/expert support is recommended for a clear picture.

Articles of Organization / Certificate of Formation

Named differently depending on the state where the company is established

• Wyoming: Articles of Organization
• Delaware & Florida: Certificate of Formation

These documents enable the company to be officially established and recognized by the state. They contain basic information such as company name, address, and Registered Agent information.

Sales Tax Permit - Sales Tax License

Businesses selling products or services in the USA must obtain a Sales Tax Permit from the relevant state. This permit allows the business to collect sales tax from customers and report it to the state. It varies by state.

Annual Report - Annual Report

In some states like Florida, companies must submit an Annual Report to the state each year reporting their activities. This report shows that the company is active and keeps its information current.

Franchise Tax - State Tax

In some states like Delaware, companies pay a fixed Franchise Tax each year. This tax is mandatory for the company to continue its existence and is usually a fixed amount.

Amazon FBA Documents

• LLC or Corporation documents
