LLC Formation Lawyer in Chicago
The limited liability company (LLC) is the most popular business structure for small and mid-sized businesses due to its combination of liability protection, tax flexibility, and operational simplicity. At Liberum Law, our LLC formation attorneys in Chicago help entrepreneurs establish LLCs that are properly structured from day one.
Forming an LLC in Illinois involves choosing and reserving your business name, preparing and filing Articles of Organization with the Illinois Secretary of State, drafting a comprehensive operating agreement, obtaining an EIN from the IRS, and registering for applicable state and local taxes and licenses.
The operating agreement is arguably the most important document in LLC formation. It governs member rights and responsibilities, profit and loss allocation, management structure, decision-making procedures, transfer restrictions, and dissolution provisions. Even single-member LLCs benefit from a well-drafted operating agreement.
Our LLC attorneys also advise on multi-member LLC structuring, series LLC formation, professional LLC requirements, and conversion from other entity types. Contact Liberum Law for a free LLC formation consultation.
Frequently Asked Questions
What are the advantages of an LLC?
An LLC (Limited Liability Company) combines the liability protection of a corporation with the tax flexibility of a partnership. Owners (members) are not personally liable for company debts. LLCs can choose to be taxed as a sole proprietorship, partnership, S-corp, or C-corp. They require less formal recordkeeping than corporations and have flexible ownership and management structures.
How long does it take to form an LLC in Illinois?
Standard Illinois Secretary of State processing for Articles of Organization is typically 10–14 business days; expedited processing (24 hours) is available for an extra fee. Liberum Law typically completes the full formation — articles, EIN, operating agreement, initial resolutions — within 5–10 business days of receiving the necessary information.
What documents do I need to form an LLC?
Core formation documents include: Articles of Organization (filed with the Illinois Secretary of State), an Operating Agreement (internal governance), Initial Resolutions (member/manager appointments), and an Employer Identification Number (EIN) from the IRS. Depending on your industry, you may also need state licenses, federal registrations, or DBA filings.
Do I need an operating agreement?
Illinois does not require an LLC operating agreement, but you should always have one — especially with multiple members. The operating agreement defines ownership percentages, capital contributions, profit/loss allocation, management structure, voting rights, dispute resolution, and what happens when a member leaves. Without one, default state rules apply, which rarely match what you actually want.
LLC vs S-corp — which is better for my business?
LLC is the entity type; S-corp is a tax election. An LLC can elect S-corp taxation. The right choice depends on income level, payroll requirements, ownership structure, and exit plans. S-corp election can reduce self-employment taxes for profitable owner-operators but adds payroll and compliance costs. We analyze the trade-off during formation consultation.
