Draft a Strong Operating Agreement for Illinois LLCs

Why an Operating Agreement Matters in Illinois

An operating agreement is the contract among the LLC’s members (and often the company itself) that sets governance and economic terms. Illinois law expressly recognizes operating agreements and generally allows broad freedom of contract about the LLC’s affairs and the members’ relationships. See https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm.

In most Illinois LLCs, the operating agreement is not a public filing with the Secretary of State; it is an internal document you keep with company records. (Formation filings are made with the Secretary of State, but the operating agreement generally is not.) See the Illinois Secretary of State’s LLC resources at https://www.ilsos.gov/departments/business_services/llc/home.html.

If your agreement does not address an issue, Illinois default rules in the LLC Act may control the outcome. See https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm (operating agreement governs to the extent it addresses an issue; otherwise the Act supplies default rules).

Start with the Business Deal: Members, Contributions, and Ownership

Strong operating agreements start by documenting the “who” and “what” of the deal in a way that is administrable years later (including after memories fade or relationships change).

• Members and ownership (percentages or “units”).
• Initial contributions (cash, property, and/or services) and how any non-cash value is determined.
• Future funding: whether additional capital can be required, who decides, and remedies if someone does not fund.
• Recordkeeping for ownership changes, contributions, and distribution history.

Illinois recognizes operating agreements that are written, oral, or implied. Even so, most businesses benefit from a written agreement signed (or otherwise properly adopted) by all members to reduce factual disputes later. See https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm.

Management Structure: Member-Managed vs. Manager-Managed

Your operating agreement should clearly state whether the LLC is member-managed or manager-managed, and who has authority to act for (and bind) the company in ordinary operations and major transactions. Illinois provides statutory management rules that can apply by default, but the operating agreement is the place to tailor authority to your actual business needs. See https://www.ilga.gov/legislation/ilcs/documents/080501800K13-1.htm (management) and https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm (operating agreement).

• Authority and approvals: spending limits, contract-signing authority, bank controls, borrowing, guarantees, asset sales, and admitting new members.
• Officers and titles (optional): who can sign and what they can sign.
• Major decisions list: define which actions require a member vote (and at what threshold).

Voting and Decision-Making: Make the Hard Calls Predictable

Many disputes arise around major decisions rather than day-to-day operations. Your agreement should define voting power (per-capita vs. pro-rata) and approval thresholds (majority, supermajority, unanimous) for key actions.

Two-member, 50/50 LLCs often face a practical risk of deadlock because neither side can reach a majority alone. It is common to address this with a tie-breaker mechanism, mediation, a buy-sell process, or (in some cases) a defined dissolution path. Illinois law provides for dissolution events and judicial dissolution in specified circumstances, which may become relevant if the company cannot function due to member conflict. See https://www.ilga.gov/legislation/ilcs/documents/080501800K35-1.htm.

Economic Terms: Distributions, Profits/Losses, and Taxes

A well-drafted agreement distinguishes among:

• Ownership (who owns the company).
• Tax/financial allocations (how profits and losses are allocated for tax/accounting).
• Cash distributions (when money is actually paid out).

These can differ. For LLCs taxed as partnerships, “allocations” and “distributions” are distinct concepts under federal tax law. See https://www.law.cornell.edu/uscode/text/26/704 (distributive share/allocations) and https://www.law.cornell.edu/uscode/text/26/731 (tax treatment of distributions), and generally https://www.irs.gov/publications/p541 (Partnerships).

Many operating agreements also include a tax distribution concept (distributions intended to help members cover pass-through tax liabilities), subject to the company’s cash needs and any lender/investor restrictions. This is largely a contractual design choice within the operating agreement framework. See https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm.

Transfers, Buy-Sells, and What Happens When Someone Leaves

Operating agreements frequently restrict transfers and set a roadmap for exits and life events (for example: voluntary withdrawal, death, disability, bankruptcy/insolvency, divorce pressure, or a member’s termination from employment).

• Transfer restrictions and consent requirements.
• Right of first refusal (ROFR) or company/member purchase options.
• Buy-sell triggers and a valuation/payment process.
• Assignee vs. member rights: whether a transferee receives only economic rights or can obtain governance rights.

Illinois has statutory rules on assignments/transfer of LLC interests and the rights of transferees, which can make careful drafting especially important. See https://www.ilga.gov/legislation/ilcs/documents/080501800K30-1.htm.

Duties, Standards of Conduct, and Liability Protections

Many Illinois operating agreements address standards of conduct, conflict-of-interest procedures, and indemnification to reduce uncertainty and set expectations for how decisions will be made and documented. The enforceability and proper scope of these provisions can be fact-specific and should be drafted to fit the company’s governance and risk profile. See generally https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm.

Confidentiality, Restrictive Covenants, and IP Ownership

If the business relies on proprietary information, customer relationships, or software/creative assets, consider provisions addressing confidentiality and intellectual property ownership. Restrictive covenants (such as non-solicitation or non-competition) should be narrowly tailored; enforceability depends on the facts, the drafting, and the applicable law.

Dispute Resolution

Many operating agreements include practical steps to manage conflict, such as:

• notice and internal escalation requirements,
• mediation before litigation, and
• arbitration (where appropriate and carefully specified).

Also consider specifying Illinois governing law and an Illinois venue clause when members or operations span multiple states.

FAQ

Do Illinois LLCs have to file an operating agreement with the state?

Typically no. In Illinois, the operating agreement is generally an internal document you keep with company records, not something filed with the Secretary of State. See https://www.ilsos.gov/departments/business_services/llc/home.html.

Can an Illinois operating agreement be oral?

Illinois law generally permits operating agreements to be written, oral, or implied, but a written, signed agreement usually provides the clearest evidence of the deal and reduces later disputes. See https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm.

What happens if our operating agreement is silent on an issue?

Illinois LLC Act default rules may apply to fill gaps. Drafting the key business points reduces the chance that an unintended default rule controls the outcome. See https://www.ilga.gov/legislation/ilcs/documents/080501800K15-5.htm.

What should we do if we are 50/50 owners?

Include a deadlock plan (tie-breaker, mediation, buy-sell, or other exit path). If the LLC cannot function due to conflict, dissolution rules may become relevant. See https://www.ilga.gov/legislation/ilcs/documents/080501800K35-1.htm.
