How to Get an EIN for Your Writer Business in Illinois (2026)

As a writer in Illinois, obtaining an Employer Identification Number (EIN) can significantly professionalize your business. Whether you're a freelance journalist, copywriter, or novelist, an EIN offers benefits beyond just tax compliance. This guide will walk you through the process of getting an EIN for your writer business in Illinois in 2026.

What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to identify business entities. It's essentially a Social Security number for your business. While not always legally required for sole proprietorships, it's often necessary for LLCs, corporations, and other business structures, and can simplify many business operations.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your writing business needs an EIN. Generally, if you're forming an LLC, corporation, or plan to hire employees, you'll need one. Even as a sole proprietor, it's beneficial for separating finances and enhancing credibility.
  2. Choose a Business Structure: Decide on your business structure (sole proprietorship, LLC, S-corp, etc.). For writers, an LLC offers liability protection. In Illinois, forming an LLC requires filing Articles of Organization with the Illinois Secretary of State and paying a $150 filing fee in 2026.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the names and Social Security numbers of responsible parties (members or owners), and the reason for applying for the EIN.
  4. Complete the EIN Application (Form SS-4): Access the IRS website and complete Form SS-4, the Application for Employer Identification Number. You can apply online, by mail, or by fax. The online application is the fastest method.
  5. Submit Your Application: Submit the completed Form SS-4 to the IRS. If applying online, you'll receive your EIN immediately. If applying by mail or fax, it may take several weeks.
  6. Receive and Store Your EIN: Once your application is processed, you'll receive your EIN from the IRS. Store this number securely, as you'll need it for various business activities, including opening a bank account and filing taxes.
