Illinois is the sixth most populous state in the U.S. with the fifth largest economy by GDP. The Prairie State boasts world-class infrastructure, education, and technology, and its diverse economy attracts people from all over the United States and the world.
If you would like to start a business in the Midwest, read our detailed guide below. It contains helpful information and steps to starting a business in Illinois.
How to Start a Business in Illinois:
1. Create a legal entity.
When starting a business, you need to determine what legal structure it will have. There are various types of business structures, but the most common ones include a sole proprietorship, a limited partnership (LP), corporation, and limited liability company (LLC).
If you decide to become a sole proprietor, you do not have to register your business with the state and may report income via your personal income tax return. However, corporations and LLCs need to be registered with the State.
It is advisable to speak to a small business attorney to assist you with arranging and setting up the legal aspects of your business structure.
For more information, refer to the Illinois state website at www2.illinois.gov.
2. Register with the Secretary of State (SOS).
If you have established a sole proprietorship or general partnership, and your business name is different from your full legal name, you will need to register an Assumed Business Name (DBA) with your county clerk's office. You can do so in-person, via email, or online.
For all other entities (LLC/LP/LLP, etc.), you will have to file Articles of Organization with the SOS. You can do so by filing the appropriate paperwork online or by mail. Keep in mind that you will also have to provide the details of a registered agent with a permanent address in Illinois, for service of process.
Next, you will need to register your business with the IRS so that you can pay federal and state taxes. Depending on your business activities, you may need to pay additional taxes, so be sure to contact your local revenue department for further information.
3. Get an Employer Identification Number (EIN).
All business entities must obtain an EIN or Federal Employer Identification Number (FEIN) if they pay wages, or file any pension or excise tax returns for the purchase and selling of alcohol, tobacco, or firearms.
You can apply for your EIN online by going to www.irs.gov. This service is free of charge.
4. Open a small business bank account.
It's important to open a bank account for your business so that you can manage your money and records separately from your personal assets.
To open a bank account, you will need your Social Security number or EIN, as well as your articles of incorporation, and business license.
5. Register with the Illinois Department of Revenue.
In Illinois, most businesses are required to be registered and/or licensed by the Illinois Department of Revenue (IDOR).
If you plan on hiring employees, buying or selling products (wholesale or retail), or manufacturing goods, you must register with the IDOR. This applies to sole proprietors as well.
You can either register electronically or fill out and mail Form Reg-1. Once you receive your Certificate of Registration, you must display it in a prominent location in your place of business.
Businesses in Illinois pay franchise tax. Read our article on franchise tax for more information.
6. Hire employees and report them to the State.
All employers must report new hires to the Illinois Department of Employment Security (IDES), and follow the requirements set out by the IDES. This includes paying unemployment insurance contributions and submitting quarterly wage reports.
You can report new employees at www2.illinois.gov/ides.
You will also need to set-up payroll to withhold taxes for your employees. To find out how to do this, read How to do Payroll: The Ultimate Guide. You can also outsource your payroll to a payroll company in Illinois, or speak to a certified tax practitioner to assist you with preparing taxes.
7. Obtain applicable state licenses and permits.
Before conducting business, you must obtain the applicable licenses and permits for your business from the Illinois Department of Financial and Professional Regulation (IDFPR). To determine which licenses and permits you need, go to www.idfpr.com.
Note that the City of Chicago has its own licensing requirements and application fees according to the industry you're in. For more information, go to www.chicago.gov.
In Illinois, many counties restrict advertising, regulate pricing or have zoning regulations. To find out if any of these restrictions apply to you, contact your city or county clerk.
8. Purchase insurance.
Acquiring small business insurance is important to protect your company from any loss, property damage, or lawsuits brought against you. And if you have permanent or temporary employees, you are responsible for providing workers' compensation in case of accidental death, injury, and occupational diseases experienced during the course of employment.
