How to get an EIN for a U.S. business

An Employer Identification Number is a federal tax ID. It is not an LLC filing, a business license, or permission to work in the United States. Apply directly with the IRS—an EIN itself is free.

1. Confirm that the entity and timing are correct

The IRS says a corporation or LLC should be formed with the state before applying, because applying too early can delay the EIN request. An EIN is generally needed for employees, certain taxes, and entities such as partnerships and corporations.

01
Use the legal entity name and state formation information consistently.
02
Identify the responsible party before starting.
03
Do not pay a third-party website merely to obtain a free IRS EIN.

2. Use the application route that fits the facts

The online IRS tool has eligibility rules, including U.S. location and responsible-party identification requirements. Applicants without a U.S. legal residence, principal office, or agency generally use the international phone, fax, or mail process described in current Form SS-4 instructions.

01
Check online eligibility directly on IRS.gov.
02
Use the current Form SS-4 instructions for non-online applications.
03
Save the confirmation notice and keep the EIN secure.

3. Do not confuse EIN with full compliance

An EIN may be used in federal tax reporting, banking, and some state processes, but state tax registration, payroll accounts, licenses, and beneficial ownership or other reports must be checked independently.

01
Create a tax and filing calendar after the number is issued.
02
Update responsible-party and address information when required.
03
Use official state and federal portals for the next registrations.
