Forming an LLC in Illinois is highly recommended. It isolates your business assets and shields your personal wealth from operating liabilities.

02. Review Local Zoning & Permits

Check local home-occupation and municipal zoning plans for Cook County to make sure your workspace is authorized.

03. File for Your Municipal License

Submit registration forms for the Chicago Business Tax Certificate to the Finance Department. Operating without a valid local license can result in fines.

04. Obtain IRS EIN & Business Banking

Secure a Federal Employer Identification Number (EIN) online to open dedicated corporate accounts and start hiring.
