"Should I form an LLC?" is one of the most common questions we hear. The answer is almost always "it depends" — which is unsatisfying but accurate. Entity selection isn't a one-size-fits-all decision. It requires understanding your specific situation, goals, and risk profile.
Here's a framework for thinking through the decision.
Start with the Purpose
Before choosing an entity type, clarify what you're trying to accomplish:
Liability protection. If your primary concern is separating business liabilities from personal assets, most entity types accomplish this — but the strength and scope of protection varies.
Tax optimization. Different entities are taxed differently. The right choice depends on your income level, whether you're taking distributions, your employment tax exposure, and your long-term exit strategy.
Operational flexibility. How many owners? How will decisions be made? Can ownership be transferred easily? These governance questions should inform entity selection, not follow it.
Investment or lending requirements. Some investors and lenders have preferences or requirements about entity type. If you're raising capital, this matters.
The Options
LLC (Limited Liability Company)
The default choice for most small businesses and real estate holdings in Illinois. LLCs offer:
- Pass-through taxation (no entity-level tax by default)
- Flexible management structure (member-managed or manager-managed)
- Strong liability protection under the Illinois LLC Act
- Minimal formality requirements compared to corporations
The operating agreement is where the real work happens. A well-drafted operating agreement addresses capital contributions, profit allocation, management authority, transfer restrictions, and what happens when things go wrong.
S-Corporation
An S-corp isn't a separate entity type — it's a tax election available to qualifying corporations and LLCs. The primary benefit is employment tax savings: by splitting income between salary and distributions, S-corp shareholders can reduce their self-employment tax burden.
This only makes sense when the business generates sufficient income to justify the additional administrative overhead (payroll, separate tax returns, reasonable compensation requirements).
C-Corporation
C-corps face double taxation — the corporation pays tax on income, and shareholders pay tax on dividends. This makes C-corps the wrong choice for most small businesses. However, they can make sense for companies planning to raise venture capital, issue multiple classes of stock, or pursue a public offering.
Partnership
General and limited partnerships are useful for specific situations — joint ventures, investment partnerships, and structures requiring different classes of economic interest. They require careful drafting because the default rules under Illinois partnership law may not match your intentions.
The Decision Framework
Ask these questions in order:
-
How many owners? Single-owner businesses default to a single-member LLC. Multi-owner businesses need to consider governance and exit provisions.
-
What's the income level? Below $60,000–$80,000 in net income, the S-corp election usually doesn't save enough to justify the complexity. Above that threshold, run the numbers.
-
Will you hold real estate? Real property generally belongs in a separate LLC — not in the operating company. This protects the real estate from business liabilities.
-
What's the exit strategy? If you plan to sell the business, entity structure affects the tax treatment of the sale. Planning for exit at formation saves significant money later.
-
Are there regulatory requirements? Certain professions (law, medicine, accounting) have restrictions on entity type under Illinois law.
Get It Right the First Time
Entity restructuring after the fact is possible but expensive. It involves new filings, new tax elections, potential transfer tax exposure, and the administrative burden of unwinding one structure while building another.
The time and cost of getting proper legal counsel at formation is a fraction of the cost of fixing the wrong choice later.
