An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. It serves to identify the entity for tax purposes, similar to how a Social Security number identifies an individual. For instance, Amazon.com Services LLC, like any other business employing individuals or operating as a corporation or partnership, is required to obtain and use an EIN for tax reporting and compliance.
This identifier is crucial for opening business bank accounts, filing taxes, and processing payroll. Its presence establishes legitimacy and facilitates compliance with federal regulations. Furthermore, it provides a historical record of the entity’s financial activities and its relationship with the IRS. The issuance of this number signifies the business’s formal recognition by the U.S. government for tax-related matters.
