A Step-by-Step Guide on How to Obtain an Employer Identification Number (EIN) for Your Illinois Business

If you’re starting a business in Illinois, obtaining an Employer Identification Number (EIN) is a crucial step. An EIN is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to identify your business for tax purposes. It is essentially the business equivalent of a social security number. In this article, we will provide you with a comprehensive, step-by-step guide on how to obtain an EIN for your Illinois business.

Step 1: Determine Eligibility:

Before proceeding, ensure that your business is eligible for an EIN. Most businesses, including sole proprietorships, partnerships, corporations, and limited liability companies (LLCs), are required to have an EIN. However, certain entities, such as estates, nonprofit organizations, and certain types of trusts, may also need an EIN. If you’re uncertain about your eligibility, consult the IRS guidelines or seek professional advice.

Step 2: Gather Required Information:

To apply for an EIN, you will need to gather the necessary information. Prepare the following details:

Legal name and trade name (if applicable) of your business.
Business address, including the city, state, and ZIP code.
Type of legal structure (e.g., sole proprietorship, partnership, LLC, corporation).
The reason for applying (e.g., new business, hiring employees, opening a bank account).
Contact information (phone number and email address) of the responsible party.

Step 3: Choose Your Application Method:

There are three methods to apply for an EIN:

Online Application: The most convenient option is to apply online through the IRS website. This method is available for businesses located in the United States or its territories. Visit the IRS website and access the “Apply for an Employer Identification Number (EIN) Online” page. Follow the prompts and provide the required information. Once completed, you will receive your EIN immediately.

Fax Application: If you prefer a non-electronic method, you can complete Form SS-4 (Application for Employer Identification Number) and fax it to the appropriate IRS fax number. The fax numbers can be found in the instructions accompanying Form SS-4. Processing time for fax applications typically takes up to four business days.

Mail Application: Fill out Form SS-4 and mail it to the appropriate IRS address based on your state. Refer to the instructions on Form SS-4 for the correct address. The processing time for mailed applications is approximately four weeks.

Step 4: Complete the Application:

Whether you choose the online, fax, or mail method, you’ll need to complete Form SS-4. The form will require you to provide the information gathered in Step 2. Additionally, you may be asked to provide additional details specific to your business structure. Ensure accuracy and double-check all information before submitting the form.

Step 5: Submit the Application:

Once you have completed the application, follow the instructions for your chosen application method:

Online Application: Submit the form electronically through the IRS website. Upon successful submission, you will receive your EIN immediately.

Fax Application: Fax the completed Form SS-4 to the appropriate IRS fax number. Keep a copy of the transmission confirmation page for your records.

Mail Application: Send the completed Form SS-4 to the designated IRS address. It is advisable to use certified mail or a reputable courier service for tracking purposes. Retain a copy of the form and mail receipt.

Step 6: Receive and Safeguard Your EIN:

After the IRS processes your application, you will receive your EIN notification. Store this number in a safe and accessible location, as you will need it for various purposes, such as tax filings, opening a bank account, and hiring employees.
