Your goal as an entrepreneur is to identify a market niche with a problem, create a product or service, and provide a profitable solution.

Here’s how it looks:

Airbnb, Uber, and Netflix show how simple solutions can solve global problems. Okay, these are big examples. But a small idea can become a billion-dollar business when it solves a common problem, like Spanx.

Today Spanx sells in over 50 countries and is worth $1.2 billion.

It makes sense for future Illinois brick-and-mortar business owners to choose a niche popular with the locals.

To cater to local interests, embrace the local flair by exploring its vibrant communities, cultural heritage, and regional specialties, then incorporate them into your business idea.

Some Illinois business ideas include: 

Validate your business idea:

Let’s say you have a business idea; now, you must validate it to confirm the demand for your solution, how much people will pay for it, and what it’ll cost to enter the market. 

Step #2: Create a Business Plan

A business plan helps unlock your idea’s potential by outlining your goals and choosing strategies to achieve them. And it also communicates your vision to potential investors who can help make it a reality. 

You’ve two business plan choices, a traditional and a one-page plan, but both include the following critical elements:

Market research

Market research helps you gain insights into your target audience’s preferences, analyze your competitors, and evaluate the potential demand for your products or services. 

Financial planning

A financial plan analyzes your start-up costs, pricing strategies, revenue projections, and economic forecasts to determine whether your business idea is worth your investment.  

And any business that requires funding will need a financial plan to secure it. 

Marketing strategy

A marketing plan outlines strategies and tactics to promote your brand awareness, differentiate it from competitors, reach your target audience, and drive customer engagement. 

Your key marketing strategies include branding, advertising, and your online presence, like your website and social media platforms.

Pro tip:

You can begin with a one-page business plan using a free template and upgrade to a traditional one when you need funding. 

Choose a Location

Your location can make or break your business, especially if your niche relies on ‘walk-in’ traffic from the street, like food or retail. 

So, looking for popular city neighborhoods or districts like Chicago, Springfield, or Peoria that match your target market and industry is important. 

But other considerations come into play when choosing the perfect location for your new business, such as:

Zoning laws and regulations:

Research Illinois zoning regulations as they decide which types of businesses are allowed where and any special requirements or limitations.

Accessibility and visibility: 

Make it easy for people to visit your business and ensure there are nearby highways, public transportation, and parking. Also, consider how visible your business will be from the street to attract potential customers.

Target audience and demographics: 

Choosing a location that aligns with your target market increases your chances of attracting and keeping customers. Research the area’s demographics to confirm it matches your target audience and has adequate population density and income levels. 

Competitor analysis:

Look at similar businesses in your chosen location and see what they offer and their reputation to determine if there’s room for your brand to stand out.

Local amenities and infrastructure: 

Consider utilities, internet access, and your location’s infrastructure to ensure it’s right for your brand. Also, take note of nearby amenities such as shopping centers, restaurants, and entertainment venues, which can attract customers and enhance the appeal of your location.

Decide if You’re an Online-Only Business

Brick-and-mortar businesses are more expensive to start than most online ventures, as it removes location from your start-up costs.

If you can begin online and expand to a physical location as your business grows, that’s a bonus for your bottom line. 

For an online business:

Step #3. Choose a Business Name

Your business name plays a significant role in establishing your brand identity. It must resonate with your target audience, convey the essence of your business, and comply with Illinois requirements.

Consider the tone and personality you want to project to create a memorable and distinctive name.

Step #4: Choose a Business Structure

There are two types of business structures: informal and formal. 

Informal structures are sole proprietorships and general partnerships; formal structures are LLCs, limited partnerships, and corporations.

Your structure choice depends on the type of business you want to start, whether you’ll have employees, and your risk appetite!

Let’s look closer so you can choose the right structure for your business:

Step #5. Set Up Banking, Credit Cards, and Accounting

Most businesses need three things to run smoothly: business banking to separate finances, credit cards for additional credit lines, and accountants to ensure IRS tax compliance.

All three offer different advantages and have certain regulations in Illinois; here’s what you need to know:

Business banking:

Entity owners (like LLCs and LLPs) need separate business bank accounts to avoid breaking the corporate veil (mixing business and personal finances), which can lead to losing liability protection.  

While general partnerships and sole proprietors can trade without a business account, using one simplifies bookkeeping and adds credibility to their brand. 

To open a business bank account in Illinois, you might need the following:

Business credit cards:

Often an essential credit line for many small business start-ups, you can use them to build your business credit history score. 

You’ll need a favorable personal credit score to get a business credit card in Illinois, and some card suppliers also require proof of income. 

New business owners who can’t get a credit card can opt for a secured business credit card, which requires a deposit as collateral.

Business accounting:

Good accounting and bookkeeping are essential when running a business. An experienced Illinois accountant can ensure you comply with all state requirements and accountancy software or apps for your daily bookkeeping needs.

Visit the Illinois Department of Revenue website for information on Illinois tax policies.

Step #6. Get Funding for Your Texas Business

All businesses require funding from family and friends, banks, or other alternatives. 

Let’s look at your Illinois funding options. 

The first place many small businesses look for loans is the Small Business Administration, which backs loans with longer repayment times and lower interest rates. 

Loans include:

Contact the Small Business Administration in your area to find out what’s available. 

State-Specific Grants and Loans:

Illinois offers grants and loans to support small businesses in certain industries, including:

Illinois Angel Investors and VCs:

Angel and VC investors offer alternative ways for small businesses to access funding.

VCs invest in larger businesses in exchange for a percentage of ownership and control over how the company runs. In contrast, Angel investors invest in smaller firms to help them start. They typically receive a percentage ownership, but generally take no part in running the business. 

Illinois VC and angel investor options:

When choosing a loan, consider the repayment terms to ensure you can afford it, and with Angel and VC investors, be sure that what you’re gaining is worth what you’re giving away. 

Step #7. Get Insured

Insurance is crucial in safeguarding your Illinois business and provides financial protection against unexpected events and liabilities. And as with all states, Illinois has specific insurance regulations:

Pro-tip:

Step #8. Obtain Permits & Licenses

Illinois does not issue a state-level business license. Still, local municipalities often require a business license or permit before you can operate in the state. 


You can find what licenses and permits your business might need on the Illinois First Stop Business Information Center.

Federal income tax and Illinois local tax

Business taxes come in multiple forms, and which you’ll pay depends upon your business structure, industry, location, and whether you have employees.

Most business owners pay the IRS federal income and self-employment tax. And employees remit 7.47% of any employee’s paycheck and pay an equal share to the IRS for payroll tax (Social Security and Medicare).  

For more information on federal tax, visit the Internal Revenue Service website.

Illinois specific regulations

Businesses also pay state and local taxes; some include:

Step #9. Find Your Team

Finding and hiring a team to help you run and grow your business is a huge task that involves following regulations and adhering to certain responsibilities as an employer.

For instance: 

People are the backbone of the business:

Employees are the core of your business and vital in shaping your brand’s direction, culture, and success. 

Hiring individuals who align with your company’s vision, values, and goals is essential because surrounding yourself with a talented and dedicated team can enhance productivity, foster innovation, and drive customer satisfaction.

You can also seek advice from experienced professionals, such as accountants or business mentors, to navigate complex financial matters, develop effective strategies, and make informed decisions.

It can be helpful to connect with other business owners who have gone through similar experiences to gain insights into overcoming challenges and maximizing opportunities.
