When you start an LLC in Illinois with Corporate Creations, we make the process simple so you can focus on building your business while we handle the paperwork.

How to start an LLC in Illinois

There are six main steps involved in setting up your Illinois LLC. When you partner with Corporate Creations, we’ll ensure that you follow the following steps so that nothing goes amiss during your formation.

1. Carry out an Illinois LLC search

Before you begin, choose a business name that’s unique and compliant with Illinois law. Your LLC name must include “Limited Liability Company,” “LLC,” or “L.L.C.” and be distinguishable from other registered entities in Illinois. The best way to do this is with an Illinois LLC search using the Illinois Secretary of State’s business entity search tool. Corporate Creations offers a name search and reservation service to ensure you get the name you want.

Find a registered agent

2. Find a registered agent

Illinois law requires every LLC to appoint a registered agent with a physical Illinois address (no P.O. boxes). The agent must be available during normal business hours to receive legal documents. You can appoint yourself, another Illinois resident, or a professional registered agent service.

3. Appoint an LLC organizer

Aside from a registered agent, you need to also appoint an LLC organizer. The organizer will sign and file your Articles of Organization with the Illinois Secretary of State. Organizers are typically members of the company, but Corporate Creations can act as your professional organizer for a streamlined process.

Choose operating and management structures

4. Choose operating and management structures

You need to think about your company’s ownership and management structure before you draft up an operating agreement. For operating structures, you can choose from a single-member LLC or a multi-member LLC. In terms of management structure, there is a member-managed LLC or a manager-managed LLC. Make sure you understand what each type entails before choosing a structure.

5. Create an operating agreement

While not required by the state of Illinois, an operating agreement is highly recommended since it helps to prevent disputes and protect your LLC’s status. It outlines important information such as ownership, management structure, and operational procedures.

File the Articles of Organization and obtain an EIN

6. File the Articles of Organization and obtain an EIN

With the above crossed off your list, you can finally file the Articles of Organization and register your LLC in Illinois. There is an expedited service available, but ordinarily the online processing time is around 5-10 business days.

Once you've officially registered your LLC, you can apply for an Employer Identification Number (EIN) form the IRS. This is necessary for hiring employees, opening business bank accounts, and filing taxes, so it’s important to get this as soon as your LLC is official. Corporate Creations can help you obtain an EIN on your behalf.
