What an EIN is
An EIN is a federal tax identification number.
EIN stands for Employer Identification Number. It is issued by the Internal Revenue Service and may be used by businesses and other entities for federal tax administration.
Whether a business needs an EIN can depend on its structure, employees, tax obligations, banking needs, and other circumstances. Requirements and application options may change.
Common uses
Why a business may need an EIN.
An EIN does not replace every registration or compliance obligation.
Hiring employees
Businesses with employees commonly need an EIN for employment-tax reporting and related administration.
Business operations
Banking, licensing, vendor, payroll, and recordkeeping requirements may call for an EIN depending on the situation.
Before you apply
Organize the business information first.
For a new LLC or corporation, state formation generally comes before an EIN application. Keep the entity’s legal name, responsible-party details, address, and formation records accurate and consistent.
For international founders
Application options may differ.
A non-U.S. owner may be able to obtain an EIN for a qualifying U.S. business. The available application route and required information can depend on the business and the responsible party.
Do not send taxpayer-identification information through a general inquiry form. Additional information may be needed later through the applicable official process.
EIN preparation path
Keep the process focused on the right information.
Issuance decisions and timing are controlled by the IRS; no outcome or timeframe is guaranteed.
Confirm the business status
Identify the entity type and whether formation or registration steps are already complete.
Review the use case
Clarify why the business may need an EIN, such as tax administration, payroll, banking, or other operations.
Organize non-sensitive details
Prepare the business information needed to understand the application path without using this public form for sensitive taxpayer data.
Follow the appropriate application route
Use the applicable IRS method based on the business and responsible party circumstances.
Starting a business
Form the entity before the tax ID step where required.
