Starting as a Sole Proprietor is easy — but as your business grows, forming an LLC can offer protection, credibility, and tax flexibility. Here’s how to decide when to make the switch.
A Sole Proprietorship is the most basic form of business ownership.
There’s no legal distinction between you and your business — you are the business.
Why people choose it:
It’s simple and inexpensive — you can start right away, often without any state filing.
You have complete control over every decision.
It’s ideal for testing an idea, freelancing, or earning side income with minimal setup.
But the trade-off:
You have unlimited personal liability. If your business is sued or owes money, your personal assets — like your savings or home — can be at risk.
You’ll pay self-employment tax on all business profits.
It can be harder to build credibility, secure funding, or grow beyond yourself.
In short:
Choose a Sole Proprietorship if you want to start fast, keep costs low, and your business risk is minimal.
Forming a company — such as a Limited Liability Company (LLC) or Corporation — means you’re creating a separate legal entity.
The business exists on its own, apart from you as an individual.
Why people choose it:
You gain personal liability protection — your home, car, and savings are generally safe from business debts or lawsuits.
You can build business credit, open dedicated bank accounts, and attract investors.
You have flexible tax options — for example, an LLC can elect S-Corp status to potentially reduce self-employment taxes.
It gives your business credibility and longevity — it can continue even if ownership changes.
But the trade-off:
There’s more paperwork and cost (state filing fees, annual reports, registered agent).
You’ll need to keep personal and business finances completely separate.
You’ll spend more time on compliance and administration.
In short:
Choose to form an LLC or Corporation if you want protection, professionalism, and a structure that can grow with your business.

Every business starts somewhere. A Sole Proprietorship lets you begin quickly, while forming an LLC helps you build a foundation for growth and protection.
The right structure depends on where you are today — and where you want to go next.
Many entrepreneurs in Illinois start simple — then switch to an LLC once revenue grows or risk increases.
Illinois Spark can guide you through forming an LLC, obtaining an EIN, and creating your operating agreement — all in one place.
To help you understand how different entrepreneurs make their business structure decisions, we’ve created a few personas — real-world examples of people who chose between starting as a Sole Proprietor or forming an LLC.
These personas show how factors like risk level, income, growth plans, and personal goals influence which structure fits best.
A persona is a short, fictional profile that represents a common type of entrepreneur or customer.
It combines real data, observed behavior, and motivations to help illustrate why someone might choose a certain path — in this case, starting as a Sole Proprietorship or an LLC.
Each persona includes:
Background – Who they are and what they do
Motivations – Why they chose their structure
Challenges – What obstacles they face
Future goals – When and why they might transition to another business type
Personas help you see yourself in the journey. Whether you’re just starting out, freelancing full-time, or expanding fast — understanding these examples can guide you toward the right structure for your business.
