An Employer Identification Number (EIN), issued by the Internal Revenue Service (IRS), serves as a unique identifier for business entities operating within the United States. This nine-digit number allows the IRS to track a business for tax purposes. A large corporation uses this identifier across all its various operations.
This identification number is crucial for several key functions. It is required for opening business bank accounts, applying for business licenses, and filing federal tax returns. Furthermore, it enables the business to legally employ individuals and fulfill payroll tax obligations. The number’s existence reflects the business’s compliance with federal regulations and its commitment to transparent financial practices.
