Forming an LLC in Illinois
LLC cost Illinois refers to the cost of creating and maintaining an LLC, or limited liability company, in the state of Illinois. This cost includes taxes, filing fees, and possibly other assorted fees, depending on your business activities.
Regardless of these fees, the cost of forming and operating an LLC in Illinois may still be less than forming and operating other business entities, since LLCs enjoy pass-through taxation, meaning that LLC profits are passed through to the LLC member’s personal income and double-taxation is thereby avoided. Because of this, LLCs are the most popular choice for small business owners. In Illinois, they can be formed by filing through the secretary of state’s website or with the help of a tax service.
Additional Startup Costs to Consider
Beyond the basic state filing fee, new Illinois LLC owners may encounter optional but common startup expenses, including:
- Name Reservation Fee: If you want to reserve your LLC name before filing, the cost is $25 for a 90-day hold.
- Registered Agent Service: While you can act as your own registered agent, hiring a professional service typically ranges from $100 to $300 annually.
- Business Licenses and Permits: Depending on your industry and location, you may need municipal or county licenses. Fees vary by jurisdiction.
- Operating Agreement Preparation: Although not required by the state, having an attorney draft an operating agreement may cost several hundred dollars.
LLC Filing Fee
In order to form an LLC in Illinois, it will be necessary to file Articles of Organization with the Secretary of State. Articles of Organization provide basic information about your LLC, such as your name, address, and registered agent’s name and address to the state. There are some fees for this filing, however. They are:
- $150 filing fee for a regular LLC.
- $400 filing fee for a series LLC.
- 2.35 percent payment processing fee if the fee payment is made with a credit card.
The State of Illinois accepts MasterCard, Visa, American Express, and Discover for this credit card payment; debit cards are not recommended. The Illinois Department of Business can provide more information on this process.
Annual Report Filing Requirement
Illinois requires all LLCs to file an Annual Report with the Secretary of State. The filing fee is $75 if submitted online or by mail. The due date is the first day of the LLC’s anniversary month each year. Failing to file on time incurs a $100 late penalty, and prolonged delinquency can result in administrative dissolution of your LLC.
Expedited and Online Service Fees
If you urgently need to form your LLC, there is an expedited filing service available through the Illinois Secretary of State’s office. The expedited service fee is $100, and it will get your Articles of Organization filed in under 24 hours (while non-expedited filings will usually take between one to two weeks). One can request expedited service either in person or by filing with the secretary of state’s CyberDriveIllinois website.
