What is an LLC?
A Limited Liability Company (LLC) is a business structure that protects your personal assets from business debts and lawsuits. It combines the benefits of a corporation (limited liability) with the flexibility and simplicity of a sole proprietorship or partnership.
Benefits of Forming an LLC in Illinois:
- Personal asset protection – Your personal savings, home, and car are separate from your business.
- Tax flexibility – Choose between pass-through taxation or elect to be taxed as an S-corp or C-corp.
- Less paperwork – Easier to manage than a corporation.
- More credibility – Customers and investors often prefer to work with an LLC over a sole proprietorship.
Step-by-Step Guide to Forming an LLC in Illinois
- Choose a Unique Business Name
Your LLC’s name must be unique and comply with Illinois state laws. It should:
- Include “LLC” or “Limited Liability Company” at the end.
- Be distinguishable from existing Illinois businesses.
- Avoid restricted words like “bank” or “insurance” unless you have special approval.
Tip: Search for your business name on the Illinois Secretary of State website to make sure it’s available.
- Appoint a Registered Agent
Illinois requires every LLC to have a registered agent—a person or company responsible for receiving legal documents on behalf of the business. Your registered agent must:
- Be an Illinois resident or a business authorized to operate in the state.
- Have a physical address (P.O. boxes aren’t allowed).
- Be available during normal business hours to receive legal notices.
Many business owners choose professional registered agent services to maintain privacy and avoid missing important legal documents.
- File the Articles of Organization
The Articles of Organization is the legal document that officially forms your LLC in Illinois. You’ll file this with the Illinois Secretary of State online or by mail.
Key details you need to provide:
- LLC name and address
- Registered agent information
- Management structure (member-managed or manager-managed)
- Business purpose (optional)
Filing fee: $150 (online or by mail, excluding any expedited handling or credit card fees).
Once approved, you’ll receive a Certificate of Organization, confirming your LLC is legally formed.
- Create an Operating Agreement (Highly Recommended)
An Operating Agreement is not required by Illinois law, but it’s highly recommended. This internal document outlines:
- Ownership percentages of LLC members.
- Roles and responsibilities of each member.
- How profits and losses are distributed.
- Rules for adding or removing members.
Having an Operating Agreement prevents disputes and ensures your LLC operates smoothly.
- Get an EIN (Employer Identification Number) from the IRS
An EIN (Employer Identification Number) is like a Social Security number for your business. You need it to:
- Open a business bank account.
- Hire employees.
- File taxes.
You can get an EIN for free from the IRS website in just a few minutes. Rincker Law can also help you with this step.
- Register for Illinois Business Taxes (If Required)
Depending on your business type, you may need to register for state taxes with the Illinois Department of Revenue.
Common business taxes in Illinois include:
- Sales tax (if you sell physical products).
- Employer taxes (if you have employees).
- Corporate income tax (if you choose to be taxed as a corporation).
- Open a Business Bank Account
To keep your personal and business finances separate, open a business checking account under your LLC’s name. This:
- Helps you track business expenses and income easily.
- Protects your limited liability status.
- Makes tax filing simpler.
Most banks require:
- Your EIN (Employer Identification Number).
- Your Articles of Organization.
- Your Operating Agreement (some banks request it).
- Comply with Illinois LLC Annual Reporting Requirements
Illinois LLCs must file an Annual Report with the Secretary of State every year.
- Fee: $75 (excluding any credit card fees)
- Deadline: One year after your LLC formation date and every year after that.
Missing the deadline results in late fees and could lead to your LLC being dissolved.
How Long Does It Take to Form an LLC in Illinois?
- Online filing: Typically approved within 10-14 business days without expedited handling.
- Mail filing: Takes 4-6 weeks to process.
- Expedited processing: Available for an additional $100 fee (24-hour approval).
Do You Need a Lawyer to Form an LLC in Illinois?
While Illinois doesn’t require a lawyer to form an LLC, working with an experienced business attorney ensures:
- Your LLC documents are properly prepared.
- Your Operating Agreement protects your interests.
- You comply with tax and legal obligations.
- You avoid costly mistakes.
