How to Apply for an EIN in Michigan

An Employer Identification Number (EIN) is essential for Michigan businesses to handle payroll, taxes, and banking. It uniquely identifies your business for federal tax purposes and is required for most business entities.

Steps to Obtain an EIN

• Determine Your Eligibility: You must have a valid Taxpayer Identification Number (such as a Social Security Number) to apply.
• Prepare Business Information: Have your legal business name, address, entity type, and responsible party details ready.
• Apply Online: The fastest method is through the IRS website’s EIN Online Assistant. This service is available Monday through Friday during business hours.
• Apply by Mail or Fax: You can complete IRS Form SS-4 and send it to the IRS by mail or fax if you prefer not to apply online.
• Receive Your EIN: When applying online, you get your EIN immediately. Mail or fax applications typically take up to four weeks.

Operational Considerations After Receiving Your EIN

• Update Business Registration: Use your EIN when registering your business with the Michigan Department of Licensing and Regulatory Affairs (LARA).
• Set up Payroll and Tax Accounts: Use your EIN to register for Michigan withholding tax and unemployment insurance if you plan to hire employees.

• Maintain Accurate Records: Keep your EIN confirmation letter and related documents for bookkeeping and compliance.

As of 2026, applying online remains the most efficient and reliable method for obtaining an EIN. Ensure your business information is accurate to avoid delays in processing.
