Key State Information
Illinois LLC filing fee: $150. Annual Report Fee: $75/year. Illinois's LLC filing fee is moderate.
Example Calculation
Let's calculate the cost to form and maintain an LLC in Illinois.
Forming a single-member LLC in Illinois: state filing fee $150, registered agent service (~$125/year), EIN from IRS (free), and a DIY operating agreement (free, or $500-$1,500 with an attorney). Illinois's annual report/franchise tax is $75/year.
Result: Year 1 total: approximately $275 (plus any optional attorney fees). Ongoing annual cost: approximately $200/year. Nationally, filing fees range from $35 (Montana) to $500 (Massachusetts) and recurring state costs range from $0 (several states) to $800/year (California) — so Illinois's cost may be far cheaper, or more expensive, than forming elsewhere. Don't form in Delaware or Wyoming just for their reputation — you'll still need to register as a foreign LLC at home and pay both states.
