Employer Identification Number
Also written: EIN
A nine-digit number assigned by the IRS to businesses for tax identification.
An Employer Identification Number, or EIN, is like a Social Security number for businesses in the United States. The IRS uses it to keep track of companies for tax purposes.
For example, if a small business wants to hire employees or open a business bank account, it will likely need an EIN. It's a crucial identifier for any business operating legally in the US.
An EIN is a unique nine-digit number issued by the Internal Revenue Service (IRS) to business entities, trusts, estates, and other organizations for tax administration purposes. It is required for businesses that operate as corporations or partnerships, have employees, file certain tax returns, or operate certain types of organizations. The EIN serves as the primary identifier for these entities in their dealings with the federal government.
