10 Steps to Start a Business in Illinois

1. Write a Business Plan

You’ve likely got a product or service in mind, as well as the details of why and how you’ll sell it. Now it’s time to put that in writing and make it official. While you can create a simple business plan that only you will use, you might make it more formal if you plan on getting a business loan. Your lender will ask to see your business plan to make sure your business is a worthwhile investment.

Before you create your business plan, you’ll need to check that your business name is available by searching on the Department of Business Services. If it’s free, you can reserve it for 90 days on the Illinois Secretary of State website.

Next, move on to your business plan, which should include:

  • business name
  • Executive summary
  • Company overview
  • Services/products and pricing
  • Startup costs
  • Earning projections
  • Competitive analysis
  • Ideal customer
  • Employee or contractor requirements
  • Marketing strategy

2. Choose a Business Structure and Registered Agent

Your business structure will determine how much risk you take on personally, as well as how you run your day-to-day operations. There are four main options:

  • Sole proprietor: This is the easiest and often cheapest way to start, but you’ll assume the most risk if someone sues your business.
  • Partnership: This is the simplest option to start a business with one or more partners, but you’ll also assume the most risk.
  • Limited liability company (LLC): An LLC protects most of your personal assets by separating your finances from the business. It takes a little more effort to form but could be worth it in the event of a lawsuit. 
  • Corporation: A corporation provides you with the most personal protection and tax breaks, but also requires the most effort and money to form and manage.

If you are forming an LLC or corporation, you’ll also need to appoint a registered agent in Illinois. This is the person who will accept legal documents on behalf of the business. It can be a person who resides in Illinois, or a company that is legally authorized in Illinois to do business.  

3. Register the Business

If you’re a sole proprietor doing business under your legal name, you won’t need to register your business name in Illinois. However, if you’re operating under another name or if you have a partnership, LLC, or corporation, you will need to register. You can register your business name with your county clerk’s office. 

You’ll also need to complete a tax registration with the Illinois Department of Revenue (IDOR) if you plan on hiring employees and manufacturing goods. The same applies to you if you will buy or sell retail or wholesale products. This registration allows you to collect sales tax. If you’ll have employees, you must also register for employer withholding taxes with the IDOR.

Some counties and municipalities in Illinois also have their own taxes aside from the state and federal taxes. You can contact your local revenue department to find out if it requires a tax registration.  

Finally, you’ll need to get a federal EIN (Employer Identification Number) from the Internal Revenue Service (IRS). If you’re starting out as a sole proprietor without employees, you’re not required to get an EIN. However, an EIN is sometimes required to open a business bank account or for payment processing, so it can be helpful to have.

4. Apply for Licenses and Permits

You’ll need various licenses and permits depending on what type of business you own. Most types of businesses in Illinois require a license from the Illinois Department of Financial and Professional Regulation (IDFPR).

Other licenses cover different factors, like health and safety, building and construction, and the environment. You can read more about what you need based on your business by visiting the Illinois Government website page on registration, licenses, and permits. 

5. Find Funding

No matter what type of business you have, you’ll likely need some sort of funding to get started. If you have relatively low costs, you might opt for self-funding and use your savings or income to pay for business costs. 

You can also ask your family or friends to lend you capital. You may choose to make it a more professional deal by writing out a repayment plan and signing it for them.

Then there are business grants – these are funds that you don't have to pay back. They’re typically issued by the government and private organizations. Most have qualifications you must meet before applying. 

You may also apply for a business loan, which you’ll need to pay back with interest. Some loans require that you put up collateral in order to get approval. Finally, you could get a business credit card. In this case, be sure to look for a 0% APR to pay less interest and fees.

6. Open Financial Accounts

Regardless of what type of business you have, it’s a good idea to keep your personal and business finances separate. This helps you protect your personal assets, like your home or car, in the event that a person sues your business. It also makes taxes and bookkeeping easier. 

You can open a business bank account online. Most banks ask for your EIN or Social Security number, an estimate of revenue, business name, and business structure. If you haven’t already opened a business credit card for funding, you may consider getting one at this point to cover smaller day-to-day purchases.

Lastly, you might sign up for accounting software to help you track your earnings and expenses. Or, you could set up your own system using a simple spreadsheet. Whatever you choose, you’ll need to consistently utilize the software to properly complete your taxes at the end of the year.

7. Get Business Insurance

There are several types of business insurance, and you won't necessarily need any of them. If you have a sole proprietorship and no employees, there are no insurance requirements. If you do have employees, you’ll need to get workers’ compensation insurance.

You may opt for general liability or professional liability insurance. These policies can help cover legal fees and other costs related to a lawsuit. This includes claims related to property damage, bodily injuries, data security breaches, and more.
