For most small businesses that operate in Illinois, forming in Illinois is the right choice. If you form in Delaware or Wyoming and do business in Illinois, you'll likely need to register as a foreign LLC in Illinois — paying fees in both states. Delaware and Wyoming make sense for businesses seeking venture capital, planning complex ownership structures, or operating entirely online without a home state nexus.
Standard LLC formation in Illinois typically takes 5–15 business days. Expedited processing is available for an additional fee and can reduce processing to 1–3 business days in most states. Online filing through the Secretary of State's website is the fastest option. Using a registered agent service like Northwest can also expedite the process.
