What is an EIN?
An Employer Identification Number (EIN), also known as a Tax ID, is a unique number assigned by the IRS to businesses for tax filing and reporting purposes. It identifies your LLC to the government, similar to how a Social Security Number identifies an individual.
Does Your LLC Need an EIN?
Most LLCs require an EIN, especially if they:
- Have employees
- Operate as a multi-member LLC
- Elect to be taxed as a corporation

Single-member LLCs may not need an EIN if they operate without employees and do not file excise tax returns.
