Most businesses operating inside Chicago city limits need a license from the Department of Business Affairs and Consumer Protection (BACP). But BACP will ask for numbers you can only get from other agencies first: a state file number, an Illinois Department of Revenue account ID, and usually an IRS EIN. Doing the steps out of order is an easy way to stall an application.
Fees went up on January 1, 2026. The Limited Business License, which covers most ordinary businesses, is now $500 for two years (it was $250). The Regulated Business License is now $1,000 for two years.

Step by step
Check that your address is zoned for your business
Every new license application goes through zoning review before BACP will process it. The city is blunt about this: do not sign a lease or make any other financial commitment until you know the zoning district allows your activity, and do not assume the previous tenant's approval carries over to you.
Look up your address on the city's zoning pages and interactive zoning map, or call the Business Call Center at 312-74-GOBIZ (312-744-6249).
Register your business with the right office
Which office depends on how your business is structured:
- LLC, corporation, LP, LLP or nonprofit: register with the Illinois Secretary of State. An LLC files Articles of Organization (Form LLC-5.5); the state fee is $150, with an optional $100 for expedited processing. LLCs then owe a $75 annual report.
- Sole proprietor or general partnership using a business name other than the owners' own names: register an assumed business name with the Cook County Clerk. The fee is $50. You must then publish a legal notice in a local newspaper once a week for three consecutive weeks, starting within 15 days, and return proof of publication within 50 days of applying. The newspaper charges separately.
A sole proprietor trading under their own full name does not need an assumed name filing.
Get an EIN from the IRS
An Employer Identification Number is your federal tax ID. BACP asks for it on the application where it applies, and you will need it for most bank accounts and for Illinois registration. Apply directly on IRS.gov. It is free; any site charging for an EIN is a paid middleman.
Register with the Illinois Department of Revenue
If you sell goods, hire employees, or otherwise owe Illinois taxes, register with IDOR before you make any sales or hire anyone. On MyTax Illinois, choose "Register a New Business (Form REG-1)." Online registrations take about one to two business days. If you sell goods, IDOR issues a Certificate of Registration, which is your sales tax permit.
The IDOR account ID is one of the numbers BACP asks for, so finish this before the city application.
Apply for the City of Chicago license
BACP decides your license type from your business activity. The official license types guide lists requirements and fees by activity. General offices, consulting firms and ordinary retail usually fall under the Limited Business License. Food, liquor, public entertainment, home repair, child care and many other activities have their own license types and extra steps. Opening a restaurant, café or grocery? See our Chicago food license guide. Home-based businesses have their own rules, so check the guide for your activity before applying.
Apply online through Chicago Business Direct, or in person at the Small Business Center in City Hall, 121 N. LaSalle St., Room 800, weekdays 8:30 a.m. to 4:30 p.m. Have these ready:
- Business name and ownership details, plus your formation documents (for an LLC, the articles of organization and operating agreement)
- Your State of Illinois file number, IDOR account ID and EIN, where they apply
- The business address and the square footage of the space
- A detailed description of everything the business does, on and off site
- Government-issued photo ID for every applicant
You need a separate license for each location.
Clear review, debt checks and inspections
After you apply, several checks run before a license issues:
- Zoning review of your activity, space, parking and, where relevant, architectural plans and driveway permits.
- City debt check. Any money you or a controlling owner owe the city, including unpaid parking tickets, blocks the license until it is resolved. Payment plans exist for some debt types.
- Fingerprinting for some license types: every owner or officer with more than a 25% interest, at $40 per person, plus an Individual History Form.
- Inspections for some license types, by the Department of Public Health (food), Buildings (public places of amusement, children's facilities) or Fire (garages, gas stations, mobile food vehicles).
Hold notices are mailed to your business address and also appear in Chicago Business Direct.
Receive your license, then track the renewal
Once inspections pass and holds are cleared, the license is mailed to your business address. Most Chicago licenses run for two years and must be renewed online through Chicago Business Direct before the expiration date. The city mails a reminder, but late renewal is your responsibility.
What delays most applications
- Signing a lease before checking zoning. If the district does not allow your activity, you are stuck with the lease and no license.
- Old parking tickets or city fines. The debt check covers every controlling owner, not just the business.
- Applying before the state and IRS steps are done. BACP needs those numbers.
- Picking the wrong license type. A business that adds food, alcohol or entertainment usually needs an additional license.
Common questions
Do I still need a city license if I have an LLC?
Usually, yes. An LLC is a state registration that creates the legal entity. The Chicago business license is a separate city approval tied to what you do and where you do it.
How much does a Chicago business license cost in 2026?
The Limited Business License is $500 for two years and the Regulated Business License is $1,000 for two years, both as of January 1, 2026. Many industry-specific licenses have their own fees. Add $150 for an Illinois LLC, or $50 plus newspaper publication for a Cook County assumed name.
How long does it take?
The state and IRS steps can be done within days online. The city license depends mostly on your license type: a simple Limited Business License with no inspections moves fastest, while food and entertainment licenses wait on inspections.
Can I apply online?
Yes, through Chicago Business Direct. You can also apply in person at the Small Business Center in City Hall. Renewals are done online.
