Why an LLC is a Great Choice for International Founders in Illinois

Steps to Form Your LLC

  1. Choose a Business Name: Select a unique name that complies with Illinois naming requirements. Check name availability on the Illinois Secretary of State's website. The name must include 'Limited Liability Company' or an abbreviation like 'LLC'.
  2. Appoint a Registered Agent: Designate a registered agent who will receive legal and official documents on behalf of your LLC. The registered agent must have a physical address in Illinois. Lovie can handle this for you.
  3. File Articles of Organization: File the Articles of Organization with the Illinois Secretary of State. This document officially creates your LLC. You can file online or by mail.
  4. Create an Operating Agreement: Although not required by Illinois, an operating agreement outlines the ownership structure, member responsibilities, and operating procedures of your LLC. This is crucial for avoiding disputes.
  5. Obtain an EIN (Employer Identification Number): Apply for an EIN from the IRS. This is required if your LLC will have employees or multiple members, or if you plan to open a business bank account. As an international founder, obtaining an EIN without an SSN/ITIN is a key challenge. Lovie can assist with this process.
  6. Open a US Business Bank Account: Open a business bank account in the US. This separates your personal and business finances. Some banks may require you to be physically present in the US to open an account. Research international-friendly banks.
  7. Comply with Illinois Regulations: Understand and comply with Illinois state and local regulations, including annual report filings and tax obligations. The annual report fee is $75. Illinois has a combined corporate income tax of 9.5% (7% income + 2.5% replacement tax).
