Do I Need a Business License for My LLC in Illinois?

Illinois does not require a general business license to operate an LLC. However, you must register for state taxes through MyTax Illinois if you have employees or sell taxable goods. Many cities and counties require local business licenses. Industry-specific licenses (professional, health, liquor) apply based on your business type.

What You Actually Need

No General State License Required

Illinois has no statewide general business license requirement for LLCs. Filing your Articles of Organization with the Secretary of State is sufficient for legal formation. You can operate without a blanket business license.

Sales Tax Registration (If Applicable)

You must register with the Illinois Department of Revenue through MyTax Illinois if you sell taxable goods or services. This is mandatory before you begin operations, though it's separate from a "business license."

Professional Licenses

If you operate as a Professional LLC under 805 ILCS 185/, you must hold the underlying professional license issued by the Illinois Department of Financial and Professional Regulation. Regulated professions include law, accounting, engineering, medicine, and dentistry. The LLC structure does not substitute for professional licensure.

Local Business Licenses

Your city or county may require a local business license or zoning approval. Requirements vary significantly by municipality. Contact your local city or county clerk's office before launching operations.

Industry-Specific Permits

Certain industries require separate permits:

Food service and restaurants (health permits)
Childcare facilities (licensing and permits)
Liquor sales or service (liquor license from your municipality)
Medical facilities (health department approval)

Key Considerations

Local Requirements Vary Widely

Even though Illinois doesn't mandate a state business license, your jurisdiction may. Always confirm local requirements with your city or county licensing office.

Tax Registration Is Mandatory

MyTax Illinois registration is legally required if you have employees or sell taxable products. This is separate from a business license but essential for compliance.

Professional LLCs Have Extra Rules

If you're forming a PLLC, you cannot operate without the required professional license. The LLC designation alone does not satisfy professional licensing requirements.
