Illinois registered agent requirements
Check Illinois’s rules for receiving legal notices and keeping the public contact record current. The local role may be called a registered agent, resident agent, statutory agent, or agent for service of process.
Open official agency forms and instructions ↗Who can serve in Illinois?
An Illinois registered agent must be an individual who is an Illinois resident, an Illinois corporation, or another entity authorized to transact business in Illinois, with an Illinois registered office that is a physical street address rather than only a P.O. box. The agent and office are public filing information and must be available for service during ordinary business hours. The entity's own officer or member can serve if the statutory qualifications and address requirements are met.
Illinois agent changes: forms and fees
Illinois corporation agent/registered-office changes use BCA 5.10/5.20 and the current corporation publication lists $25.00 regular with a $50.00 expedited amount. LLC agent or office changes use LLC 1.36/1.37 and the publication lists $25.00 online with a separate paper/expedited amount. Use https://www.ilsos.gov/departments/business-services.html and the corporation/LLC forms pages; the agent must consent and the replacement must have a compliant Illinois office.
Resignation, notice, and effective dates
Illinois corporations file the applicable BCA statement of resignation/change and LLCs use LLC 1.35 for agent resignation. The LLC publication lists a $5.00 online resignation fee and a $50.00 paper/route amount; corporate resignation pricing is shown in the current BCA fee table. A resigning agent must follow the statutory notice and effective-date rules and does not appoint a successor. The entity must promptly name a qualified Illinois agent or risk revocation and missed process.
Consequences of a missing agent or address
An Illinois entity that lacks a valid registered agent or registered office can miss service of process, suffer default judgments, lose good-standing status, have its authority revoked or be administratively dissolved, and incur reinstatement and delinquent-report costs. The Secretary may receive process in limited statutory circumstances, but that mechanism is not a substitute for maintaining the appointment. The public registry is not a shield against the consequences of an invalid address or unanswered lawsuit.
Confirm the change reached the public record
Keep the accepted filing and confirm the agent or service address shown for the business. Arrange forwarding of legal notices during the change, and check which contact information will be public before supplying a home address.
