Step by step
How to form the Illinois LLC.
Choose and check the LLC name
The name must satisfy Illinois's naming rules and be distinguishable in the state records. A preliminary search helps, but the filing office makes the final availability decision.
Appoint a registered agent
The agent receives official and legal documents and generally needs a physical address in Illinois. Bizee includes registered-agent service for the first year with an eligible formation; review the renewal terms.
File the Articles of Organization
Provide the required LLC, registered-agent, address and organizer information and pay the current state filing fee, listed below as $150.
Bizee's Basic option has a $0 formation service fee plus the state fee. Chris generally recommends reviewing Standard when you want EIN preparation and core startup documents included.
Prepare the operating agreement
Document ownership, management, authority and financial rules even when the agreement is not filed publicly. Choose a free starting point, a more comprehensive template or custom drafting based on the LLC's needs.
Complete the EIN, banking and funding setup
Obtain the EIN when appropriate, open a separate company account and document money entering the LLC as revenue, a contribution, a loan or another properly classified transaction.
Illinois provides a separate and more expensive filing framework for a series LLC.
