Starting a Business in Illinois

Business Start-up Checklist in IllinoisPerhaps the most important, but often undervalued step to starting a business in Illinois is writing a business plan.  While the business plan is most often thought of as something that is required to get a business loan, it can also serve as a roadmap for your business.  Starting and running a business is complex and there are so many parts in motion, it’s next to impossible to keep track of everything – and that’s where the business plan comes in.

When most people think of business plans, most think about a formal document that’s as thick as a text book.  Those don’t happen much anymore because they just aren’t useful.  If you are writing a business plan for the bank, some formality is in order but you should also have a business plan that you can use to execute your vision, even if it’s just scribbled on notebook paper.

Select a Business Entity in illinois

The second step in starting a business in Illinois is selecting a business entity.  The business entity is how a business is legally organized to do business.  The four primary types include the sole proprietorship, partnership, corporation and LLC.  Each has pros and cons and a short description of each is below.

Sole Proprietorship: A sole proprietorship is an individual that decides to go into business.  This is easiest and least expensive of the four to set up but has a serious potential downside which is unlimited liability.  This unlimited liability opens the business owner up personally should the business be sued.   There is no filing for a sole proprietorship in Illinois.

General Partnership: A general partnership is similar to the sole proprietor, except it involves two or more people conducting a business together. Like the sole proprietorship, there is no formal filing and also like the sole proprietorship, the partnership has unlimited liability.

Corporation: The corporation is more complex to form than the sole proprietorship or partnership but that complexity provides the owner with the ability to protect their personal assets through liability protection. If the corporation gets sued, the owner’s personal assets should be safe.

The cost to form a corporation in Illinois is at a minimum, $175.  The Articles of Incorporation must be filed with the Illinois Secretary of State

Limited Liability Company (LLC): The LLC is similar to the corporation because of the liability protection but provides the ease of operation of a sole proprietorship by eliminating the administrative requirements of the corporation. 

The initial cost to form an LLC in Illinois is $150.  The Articles of Organization are filed with the Illinois Secretary of State.

HOW TO FILE A DBA IN ILLINOIS FOR SOLE PROPRIETORSHIPS & GENERAL PARTNERSHIPS

If you are a sole proprietorship or general partnership in Illinois and doing business under your full first and last name, John Smith for example, there is no filing, but if the business will operate under a trade name or fictitious business name like John Smith’s Handyman Service, Mr. Handyman, etc, you will need to file an Assumed Business Name Registration, commonly known as a DBA (Doing Business As) with the county where the business is located.

The assumed name is a one-time cost and initial filing costs vary by county in Illinois.  Expect to spend $10-$50 for the county filing and an additional $30-$100 for the newspaper advertising. 

HOW TO RESERVE A BUSINESS NAME IN ILLINOIS FOR A CORPORATION OR LLC

Corporations and LLCs have to pick a name at the time of filing for the entity and each corporation/LLC has to be uniquely named. 

To check the availability of names, visit the Illinois Secretary of State.

Registering does not necessarily keep others from using the business name.  For more details on registering a business name and protecting it with a trademark, click here.

The Employer Identification Number or EIN (sometimes referred to as the Federal Employer Identification Number or FEIN) is a unique nine digit number from the IRS to identify a business operating in the U.S.  Much like what a social security number is to a person, the EIN is essentially a social security number for a business.  While most businesses will need to get an EIN, some do not need to.

Businesses that are required to get an EIN include partnerships, corporations or LLCs OR sole proprietorships with employees.

A sole proprietorship with no employees isn’t required to get an EIN and would simply use the owner’s social security number instead.

how to get a business license in illinois

Starting a business in Illinois may require business licenses and registrations before being legally able to operate.  A few common licenses a business may need in Illinois include;

State of Illinois Business Registration Any business buying or selling items (wholesale or retail), hiring employees, or manufacturing goods needs to register with the Illinois Department of Revenue and obtain an Illinois Business Tax Number (IBT).

Local Business Licenses – Most cities, towns and/or counties in Illinois require a business to register, even occasionally those that are home-based businesses.   Each local entity has its own rules for business activity, so requirements vary depending on location as some require a business license while others have requirements for zoning, building/ building improvements, signage requirements, liquor licenses, etc.  

The City Hall, County Clerk, Chamber of Commerce and/or Economic Developer are all good places to get more information regarding local business licenses. 

Occupational Licenses – A variety of professionals in the state are regulated such as doctors, physical therapists, veterinarians, detectives, cosmetologists, barbers, architects, massage therapists and many more.

Finding Financing for a Business in Illinois

Getting the funds together to finance a business startup can be a time consuming process.  Similar to getting a home loan, the bank is going to want lots of documentation on your personal finances in addition to a solid idea and business plan.

As a rule of thumb, banks will want to see the owner invest 15%-25% of their money (equity) into a start-up business.  That can include cash but also any buildings, tools, vehicles, inventory and equipment that will be used in the business.

There are a number of small business loan options, but the primary ones that are used by small businesses include:

Conventional Bank Loans – These are available at most local banks and are where most entrepreneurs start when looking for a loan.

Loan Guarantee – When a loan is riskier than the bank wants to take on, many have the option to use the Small Business Administration (SBA).  This is a federal program that provides a guarantee to the bank that will pay a percentage of the loan should the business owner default.

Alternative Lenders – A newer type of lender has emerged to make business loans online.

Revolving Loan Funds – Several communities, economic development agencies, etc. offer revolving loan funds to businesses as a way to encourage investment and job creation.  They are often low interest and approval is typically not as strict as a bank since job creation in the community is a priority.

Expect the loan approval process to take anywhere from 2 weeks to 6 months (and possibly more) depending on the amount being borrowed, complexity of the project and owner’s personal financial condition.

Credit Score
Before stepping into a bank for financing, it is a good idea to know your credit score.  A major factor in getting start-up business loan approval is the owner’s credit score.  Typically scores above 650 are considered viable so if you aren’t sure, get a copy of your credit report.

Federal & State Unemployment Insurance – Employers are responsible for paying taxes to compensate workers who have recently lost their jobs, which is through federal & state unemployment insurance.

Worker’s Compensation Insurance – Workers’ compensation provides compensation benefits and covers medical costs to employees injured on the job.    Worker’s Compensation Insurance is administered through the Illinois Workers’ Compensation Commission.

Labor Laws – Employers should also understand the various regulations and laws pertaining to employees. If you plan to hire employees, learn the rules that apply to your business. Federal laws, depending on your sales volume and number of employees, may supersede state laws.
