Employer Identification Number (EIN)

What is Employer Identification Number (EIN)?

An employer identification number (EIN) is a unique number that the Internal Revenue Service issues to a company. The EIN of a company is irreversible, like a taxpayer’s fingerprint. It never goes out of date or is repurposed for another company. Your Federal Employer Identification Number, or FEIN, may also refer to your EIN.

Why Employer Identification Number (EIN) Matters

Any business required to get an EIN by federal law will also need one by state law. A State Employer Identification Number, or State EIN, will be given to your company by your state, and you can use it to both submit state tax returns and hire staff.
