Kane County Business License: Aurora, Elgin and Unincorporated Kane

Kane County, Illinois has no countywide business license. Instead, licensing requirements depend on where your business operates, whether in Aurora, Elgin, unincorporated Kane County, or another municipality. This fragmented system means your licensing pathway varies significantly based on your city or township.

If you are opening a business in Kane County, you will need to understand your specific city or township requirements before you can legally operate. This guide covers the three most common scenarios: Aurora, Elgin, and unincorporated areas. It also addresses Kane County Health Department permits and state-level requirements that apply across the entire county.

Kane County Has No Unified Business License

Unlike some counties that issue a single business license covering the entire area, Kane County operates under a decentralized system. Cities and villages within Kane County issue their own licenses. Unincorporated Kane County has no general county business license (confirm with the county), though county zoning and building rules still apply.

Businesses that sell taxable goods or have employees must register with the Illinois Department of Revenue, but that separate state step does not eliminate local city or village requirements. You must comply with both your local municipality and the state.

Aurora: Free Business Registration

Aurora is the largest city in Kane County and runs a business registration rather than a fee license. The city FAQ says registration is free through December 31, 2025 and publishes no later fee, so confirm current status with Aurora Development Services. Home-based businesses are exempt.

Aurora Registration Process

To register a business in Aurora:

1. Contact City of Aurora Development Services or visit the city website to obtain a registration form.
2. Complete the registration form with your business name, address, owners, and industry classification.
3. Submit the form to the city (the city FAQ describes registration as free; confirm current status).
4. Obtain your registration confirmation.
5. Comply with any additional city permits required by your industry (signs, parking, food service, etc.).

Some Aurora businesses may still need specific permits depending on their operations, such as health permits for food businesses or fire permits for certain uses. Registration does not substitute for those specialized permits.

Operating Without Registration Is Illegal

Even though Aurora registration is free, operating without it is a violation. Confirm the exact current process and any fees by contacting Aurora Development Services directly, as city requirements can change.

Elgin: Annual Business License Required

Elgin, the second-largest city in Kane County, requires every business to hold a general business license, renewed by February 1 each year and issued together with a certificate of occupancy.

Elgin License Requirements

New, relocating or changed-ownership businesses file a Business Application with a $230 fee, which covers both the occupancy permit and the general license. Renewing the general business license costs nothing, but specific licenses such as food, liquor, video gaming and tobacco carry their own annual fees.

Contact the City of Elgin to confirm which specific licenses your business needs and their current fees.

Elgin License Application

1. Obtain an application from the Elgin Business License Division.
2. Complete the application with business details and owner information.
3. Submit the application with payment.
4. Receive your license, typically valid for one year.
5. Renew annually before your license expires.

Elgin general business licenses are due by February 1 each year. Plan your renewal ahead of that date to avoid operating without a valid license.

Unincorporated Kane County: County Clerk Filing

If your business operates in unincorporated Kane County (outside Aurora, Elgin, and other incorporated municipalities), there is no city license to obtain. Sole proprietors and partnerships anywhere in Kane County that use an assumed name file a certificate with the Kane County Clerk.

Assumed Business Name Filing Requirements

Under Illinois law, sole proprietors and general partnerships in Kane County must register their assumed business name (also called a "doing business as" or DBA). Corporations and limited liability companies formed in Illinois are exempt if they use their legal registered name.

How to File in Kane County

1. Complete the Assumed Business Name certificate form from the Kane County Clerk.
2. Pay the filing fee (confirm the current fee with the county clerk's office, as rates may vary).
3. Publish notice of your assumed name in a newspaper of general circulation in Kane County for three consecutive weeks.
4. File the published proof with the county clerk.
5. Receive your certificate of registration.

The county clerk assumes name filing is required before you can legally operate as a sole proprietor or partnership under a name other than your legal name. The three-week publication requirement takes time, so plan accordingly.

Contact Kane County Clerk

The Kane County Clerk's office handles all assumed name filings for unincorporated areas. Contact them directly to confirm current fees and publication requirements.

Kane County Health Department: Food Business Permits

If your business serves, prepares, or sells food, you must obtain a permit from the Kane County Health Department. This applies throughout Kane County, but the parts of Aurora and Elgin that lie in neighboring counties may fall under those counties' health departments, so confirm which department covers your address.

Food Service License Requirements

The Kane County Health Department issues food establishment permits to restaurants, cafes, food trucks, bakeries, catering operations, and other food businesses. You must obtain a permit before you begin operations.

Permit Application Process

1. Contact the Kane County Health Department to request a food establishment permit application.
2. Complete the application with details about your food business, menu, preparation methods, and facility.
3. Schedule a facility inspection by the health department.
4. Correct any deficiencies found during inspection.
5. Receive your food establishment permit.

Food permits are typically valid for one or two years and require renewal. Annual inspections may be required to ensure ongoing compliance with health codes. Failure to obtain a permit before opening is a violation and can result in fines or closure.

Contact Kane County Health Department

Reach out to the Kane County Health Department directly for current food permit fees, inspection procedures, and timelines. They can advise on whether your specific food business model requires a permit.

State of Illinois Business Registration

In addition to any local city or county license, you must register your business with the Illinois Department of Revenue through MyTax Illinois. This is a separate, state-level requirement for businesses that sell taxable goods or have employees.

MyTax Illinois Registration

Complete registration through MyTax Illinois (Form REG-1) online. The process is free and typically processes in one to two business days online. Once registered, you receive a Certificate of Registration if your business is a retailer, and you can obtain an Illinois tax ID for withholding and filing purposes.

Many businesses, including those in Kane County, proceed with state registration before or alongside their local licensing.

Sales Tax in Kane County

Kane County is in the Chicago metropolitan area and has multiple municipal sales tax rates depending on which city or unincorporated township your business operates in. Illinois state sales tax is 6.25 percent, and local municipalities add additional taxes on top.

Under the IDOR rate table effective August 1, 2026, combined general rates run from 7.25 percent in unincorporated Kane County to about 9.25 percent in some towns, including the RTA tax. If you operate across multiple cities or towns in Kane County, you may be required to collect different sales tax rates at different locations. Confirm your exact rate with your city or the Illinois Department of Revenue.

Retailers must display their Certificate of Registration at the place of business as proof of tax registration.
