How to Start a Sole Proprietorship in Illinois

Illinois Sole Proprietorships: Everything You Need to Know

A sole proprietorship is the simplest and most accessible form of business ownership. It refers to a single-owner business that is not registered as a corporation or a limited liability company (LLC). If you’re a freelancer, independent contractor, or operate a business under your own name, you may already be a sole proprietor without realizing it. However, understanding the process of formalizing your business and complying with Illinois state requirements is essential for operating legally and protecting your interests. At Next Era Legal, we help business owners in Chicago and across Illinois navigate these steps seamlessly. Contact us today for personalized guidance on starting your sole proprietorship.

Steps to Start a Sole Proprietorship in Illinois

Establishing a sole proprietorship in Illinois does not require filing formal legal documents with the state government. However, taking these key steps will help you formalize your business and ensure compliance:

1. Choose a Business Name

You can operate under your legal name or adopt a trade name, also known as a “Doing Business As” (DBA). If you choose a DBA, ensure that it is unique and complies with Illinois naming regulations. Conduct a name search through the Illinois Secretary of State and the U.S. Patent and Trademark Office to verify availability.

2. Register Your DBA with the County Clerk

If you decide to operate under a DBA, you must register it with the county clerk’s office in the county where your business operates. In Cook County and other Illinois counties, registration typically requires:

  • Filing a DBA application.
  • Paying a filing fee (varies by county).
  • Publishing your DBA in a local newspaper for public notice, as required by Illinois law.

3. Obtain Necessary Licenses, Permits, and Zoning Clearances

Depending on your business type and location, you may need specific licenses or permits. For example:

  • Restaurants must obtain food service permits.
  • Construction businesses may require contractor licenses.
  • Home-based businesses must comply with local zoning laws.

Consult with local government offices or use the Illinois Department of Commerce and Economic Opportunity’s resources to determine the licenses and permits required for your industry.

4. Obtain an Employer Identification Number (EIN)

While sole proprietors without employees can use their Social Security Number for tax purposes, obtaining an EIN from the IRS is highly recommended. An EIN is often required for:

  • Opening a business bank account.
  • Hiring employees.
  • Enhancing security by reducing identity theft risks.

Applying for an EIN is free and can be completed online.

Frequently Asked Questions

How Do I Convert a Sole Proprietorship to an LLC in Illinois?

To transition from a sole proprietorship to an LLC in Illinois, you’ll need to:

  1. File Articles of Organization with the Illinois Secretary of State.
  2. Obtain a new EIN for the LLC.
  3. Update your business licenses and permits.
  4. Notify clients, vendors, and financial institutions of the change.

Converting to an LLC can offer liability protection and enhance credibility, making it a worthwhile step for growing businesses.

Can a Sole Proprietor Use a DBA?

Yes, a sole proprietor can operate under a DBA. For example, instead of using your legal name, you can register “Chicago Creative Solutions” as your DBA. However, this does not change the business’s legal structure, which remains a sole proprietorship.
