Illinois LLC Operating Agreement Starter Template

1. Company and Effective Date

This Operating Agreement governs [Exact LLC Name], an Illinois limited liability company, effective [Date].

The Company’s principal office is [Address].

The Company conducts [Description of Lawful Business], together with any other lawful activities approved in accordance with this Agreement and permitted by applicable law.

2. Members and Contributions

The Members of the Company are identified in Schedule A.

For each Member, Schedule A should identify:

  • Name
  • Address
  • Contribution description
  • Agreed value of the contribution
  • Contribution due date
  • Percentage interest or other applicable economic interest

No Member is required to make an additional contribution unless that obligation is approved or otherwise established through the procedure specified in this Agreement.

The Members should distinguish carefully between capital contributions, economic interests, and voting rights. These concepts do not necessarily need to use identical percentages.

3. Management and Authority

The Company is [Member-Managed OR Manager-Managed].

The authorized Managers are [Names, if applicable].

Authority to conduct the Company’s ordinary business includes [Describe Scope of Ordinary Authority].

The following actions require [Specified Approval Threshold]:

  • Borrowing more than [Amount]
  • Selling or disposing of substantial Company assets
  • Admitting a new Member
  • Entering transactions outside the ordinary course of business
  • Amending this Agreement
  • [Other Reserved Decisions]

The Company will maintain appropriate written evidence of material approvals.

4. Voting and Reserved Decisions

Voting power is determined according to [Ownership Percentage / Equal Voting / Other Specified Method].

Routine business decisions require approval of [Threshold].

Reserved or extraordinary matters require approval of [Threshold].

Notice and voting procedures will be conducted through [Method], with [Notice Period] notice where required.

Transactions involving an actual or potential conflict of interest should be disclosed and considered in accordance with this Agreement and applicable Illinois law.

5. Allocations and Distributions

Profits and losses will be allocated according to [Allocation Method Reviewed With Tax Adviser].

Cash distributions will be considered [Monthly / Quarterly / Annually / At Another Specified Time], subject to:

  • Available cash
  • Company liabilities
  • Reasonable operating reserves
  • Contractual restrictions
  • Applicable legal restrictions on distributions

The Company’s tax-distribution policy is [Policy].

An allocation of taxable income to a Member does not, by itself, guarantee that the Company will make an equivalent cash distribution.

Tax provisions involving non-pro rata or otherwise unusual allocations should be reviewed by a qualified tax professional.

6. Records and Banking

The Company will maintain its important records at [Physical Location or Electronic Record System].

Records should include, as applicable:

  • Current ownership schedule
  • Financial and accounting records
  • Tax returns and supporting records
  • State filings
  • Material contracts
  • Member and manager approvals
  • This Operating Agreement and amendments

Company funds should be properly recorded and maintained separately from Members’ personal funds.

Authorized bank signers are [Names or Roles].

Member rights to Company information and records remain subject to applicable Illinois law.

7. Transfers, Admission, and Member Exits

A proposed transfer of an ownership interest must follow [Notice, Consent, Right of First Refusal, or Other Transfer Procedure].

Admission of an additional or replacement Member requires [Approval Procedure].

For retirement, death, disability, voluntary departure, or a proposed buyout:

  • The valuation method is [Method].
  • The valuation date is [Rule].
  • Payment terms are [Terms].
  • Funding arrangements, if any, are [Insurance / Installments / Company Funds / Other Method].

The parties should distinguish between transferring an economic interest and becoming a Member with governance or management rights. A transfer of economic rights does not necessarily provide the transferee with the full rights of a Member.

8. Deadlocks and Disputes

If Members cannot resolve a material decision, the deadlock procedure will be:

[Negotiation → Mediation → Buyout Procedure / Arbitration / Litigation / Other Agreed Process]

The agreement should specify:

  • When a deadlock exists
  • Who initiates the procedure
  • Applicable notice periods
  • How mediation or another dispute process is selected
  • Whether a buyout mechanism applies
  • How the business operates while the dispute remains unresolved

A clear deadlock procedure is particularly important for LLCs with two equal owners.

9. Amendments

This Agreement may be amended only with approval of [Required Threshold].

Amendments should be documented in writing and maintained with the Company’s records.

If an amendment changes information that must also be reported to the Illinois Secretary of State or another government authority, the Company should make the appropriate external filing separately.

10. Dissolution and Winding Up

The Company may be dissolved following [Authorized Decision Process] and as otherwise provided by applicable Illinois law.

The person responsible for winding up the Company’s affairs will be [Person / Manager / Member / Selection Process].

Winding up may include collecting Company assets, resolving liabilities, addressing creditors, completing tax and regulatory obligations, and distributing remaining assets in accordance with applicable law and this Agreement.

11. Signatures

Each Member should sign and date the completed Operating Agreement.

Member: [Name]
Signature: _________________________
Date: _________________________

Member: [Name]
Signature: _________________________
Date: _________________________

Where appropriate, a Manager who is not a Member should separately acknowledge acceptance of the Manager’s role and responsibilities.

Attach Schedule A and any approved schedules addressing authority limits, contributions, ownership, buyout provisions, or other material terms.

Each Member should receive the same complete executed version.

What These Clauses Are Designed to Prevent

An operating agreement is most valuable when it resolves important questions before a disagreement occurs.

Two owners contribute different amounts but expect equal control

Clause to Settle Before Signing

Separate economic and voting provisions

Problem if Left Vague

Contribution percentages may incorrectly be treated as voting percentages

A manager wants to obtain a substantial business loan

Clause to Settle Before Signing

Borrowing limit and reserved approval

Problem if Left Vague

Internal authority may be disputed after the commitment is made

An owner stops working but retains an ownership interest

Clause to Settle Before Signing

Work obligations, compensation, and buyout provisions

Problem if Left Vague

Employment, ownership, and compensation can become confused

A Member dies

Clause to Settle Before Signing

Succession, transfer, and admission provisions

Problem if Left Vague

An economic successor may incorrectly be treated as automatically receiving management rights

Two 50/50 owners cannot agree

Clause to Settle Before Signing

Deadlock mechanism

Problem if Left Vague

Important decisions may become impossible to make

These examples are drafting prompts and do not represent actual client matters.

Understand the Limits of an Illinois Operating Agreement

Illinois law gives LLC owners substantial flexibility to structure their internal affairs through an operating agreement, but that flexibility is not unlimited.

Section 15-5 of the Illinois Limited Liability Company Act establishes rules concerning the scope and effect of operating agreements and identifies statutory provisions that an operating agreement cannot override or may modify only within specified limits.

For example, an operating agreement cannot simply eliminate every statutory information right or use broad language to excuse conduct that Illinois law does not permit the parties to excuse.

Fiduciary-duty provisions are particularly sensitive. Owners should not assume that inserting a general statement such as “the Members owe no duties” effectively eliminates duties or protects conduct in every circumstance.

If the parties intend to modify fiduciary duties, liability standards, or conflict-of-interest rules, the provisions should be drafted specifically and reviewed against current Illinois law.

The Operating Agreement Is Not the Articles of Organization

An operating agreement is an internal governance document.

It is different from the LLC’s Articles of Organization filed with the Illinois Secretary of State.

The agreement ordinarily addresses matters such as:

  • Ownership
  • Management
  • Voting
  • Contributions
  • Distributions
  • Transfers
  • Member exits
  • Buyouts
  • Disputes
  • Dissolution

The Articles of Organization establish the LLC with the state and contain the information required for the public filing.

Keep the operating agreement with the Company’s internal records and ensure that its management structure is consistent with applicable public filings and the way the business actually operates.

An Operating Agreement Does Not Guarantee Liability Protection

Having a written operating agreement can help document the LLC’s ownership and internal governance, but the document itself is not a guarantee against personal liability.

Personal guarantees, an individual’s own conduct, applicable statutory rules, and other circumstances may create personal exposure despite the existence of an LLC and operating agreement.

Appropriate contracts, insurance, accounting practices, regulatory compliance, and professional advice remain important.

Before You Sign

Before executing the operating agreement, confirm that:

  • Every placeholder has been completed.
  • No alternative drafting options remain in the document.
  • Member names and ownership information are accurate.
  • Contribution amounts and obligations are clearly stated.
  • Economic percentages reconcile.
  • Voting rights are clearly defined.
  • Management authority is practical for daily operations.
  • Spending and borrowing limits are workable.
  • Reserved decisions have clear approval thresholds.
  • Transfer restrictions are understandable.
  • Buyout provisions contain a usable valuation method.
  • The parties have addressed death, disability, and voluntary departure where appropriate.
  • Deadlock provisions are workable.
  • Distribution provisions comply with applicable law.
  • Tax provisions have been reviewed where necessary.
  • All Members receive the same final executed agreement.

Nonstandard tax allocations should be reviewed by a tax professional.

Tailored legal assistance may also be appropriate where the LLC involves unequal control rights, outside investors, significant assets, personal guarantees, regulated professional services, complex succession arrangements, or series structures.

Conclusion

An Illinois LLC operating agreement should do more than repeat generic legal language. It should provide practical answers to the questions the owners are likely to face while operating the business.

Start by determining whether the LLC will be member-managed or manager-managed. Then clearly address contributions, voting, management authority, distributions, transfers, buyouts, disputes, and winding up.

For a simple single-member LLC, those provisions may be relatively straightforward. For a multi-member company, the operating agreement becomes considerably more important because it establishes the rules the owners will rely on when their interests no longer align.

Complete every placeholder, remove competing alternatives, confirm that the agreement matches the Company’s actual structure, and obtain tailored advice where ownership, tax, regulatory, or liability issues require more than a general template.
