A business tax ID, also known as an Employer Identification Number (EIN), is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to businesses operating in the United States. It is used to identify the business for tax purposes and is required for various business activities, such as filing taxes, opening a business bank account, and hiring employees.
Obtaining a business tax ID is relatively straightforward and can be done online, by mail, or by phone. The IRS provides a dedicated webpage where businesses can apply for an EIN. The application process typically takes a few minutes, and the EIN is usually issued within a week.
