What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, allowing the IRS to identify your company for tax purposes. Whether you're forming an LLC, corporation, or other entity type, an EIN is often necessary to operate legally and manage your finances.

How to Apply for an EIN
