Educational guide, not legal or tax advice.

An EIN is a federal tax identification number issued by the IRS. An Arizona LLC may need one for banking, employees, multi-member ownership, federal tax filings, Arizona TPT licensing, withholding, unemployment, or vendor onboarding.

The EIN is free when obtained directly from the IRS. It is not included in Arizona LLC formation.
