Is a Single-Member LLC Protected in Illinois?
Yes. A single-member LLC in Illinois receives liability protection under 805 ILCS 180. The owner's personal assets are shielded from business debts and lawsuits against the company. Illinois law does not require multiple members to form an LLC or maintain liability protection—one person is sufficient. However, protection depends on maintaining the LLC as a separate legal entity and not commingling personal and business funds.
How Liability Protection Works
Under 805 ILCS 180, an LLC is a separate legal entity. Members are not personally liable for the debts or obligations of the company or the wrongful acts of employees or agents. This protection applies equally to single-member and multi-member structures.
The key requirement: treat the LLC as a separate business. Maintain a dedicated business bank account, keep records, and avoid using company funds for personal expenses. Courts may pierce the corporate veil and hold you personally liable if you fail to respect the LLC's separate identity.
Charging Order Protection
Illinois provides standard charging order protection under 805 ILCS 180. If a creditor obtains a judgment against you personally, they cannot seize LLC assets directly. Instead, they receive a charging order, which limits them to distributions the LLC makes to you. This protection applies to single-member LLCs and significantly restricts creditor remedies.
Operating Agreement Considerations
An operating agreement is not legally required under 805 ILCS 180/15-5, but it is strongly recommended—especially for single-member LLCs. A written agreement documents your intent to maintain the LLC as a separate entity, which strengthens liability protection if challenged in court. Without one, Illinois default rules apply.
Maintaining Protection
To preserve liability protection:
- Open a dedicated business bank account
- Keep separate accounting records
- File Articles of Organization with the Illinois Secretary of State
- Maintain written operating agreement documentation
- File annual reports on time
- Avoid personal guarantees on business obligations
Failure to observe these formalities could expose you to personal liability under piercing-the-veil doctrine, though Illinois courts apply this standard strictly.
