Verdict: Minnesota wins for most businesses
For most Minnesota-based businesses, forming locally in Minnesota is the smarter choice. You avoid paying fees in two states and managing compliance in both. Illinois only makes sense if your business genuinely operates there, and even then the total costs deserve a hard look.

Compare LLC Costs: Minnesota vs Illinois
Minnesota
Illinois
Costs include every mandatory state charge: the filing fee, the report fee (annualised where a state files biennially), any state entity-level tax shown in its own row above, a one-time publication cost where a state requires publication, and any one-time registration charge a state requires before the LLC may trade. Annualising makes the 1, 3 and 5 year rows a cost of ownership rather than a payment schedule: a biennial state charges its whole report fee in the years it falls due and nothing in between. Entity-level taxes that only apply after a corporate election, or above an owner or income threshold, are excluded and flagged on the state's own cost page. New York's publication cost is carried at a $250 floor, roughly $200 of newspaper cost in a low-cost county plus the $50 Certificate of Publication fee. No county-clerk-designated New York City newspaper publishes a rate card, so the four-figure NYC estimates in wide circulation cannot be traced to a primary source and are not asserted here; budget for materially more than the floor if you file in a NYC county. Montana's annual report is free when filed by April 15 and $35 after, a waiver the Secretary of State applies at its discretion. Every fee was verified against the state's own fee schedule, statute, or revenue authority on 29 July 2026. Excludes registered agent and legal fees.

Filing Fees & Formation Costs
Minnesota charges $135 to form an LLC, while Illinois charges $150. Minnesota is $15 cheaper upfront. The cost that usually gets overlooked: if you form in Illinois but operate in Minnesota, you must also register as a foreign LLC in Minnesota (a $185 filing) and maintain a registered agent in Illinois (typically around $150 per year). That puts the realistic first-year cost of the Illinois route at roughly $485, versus $135 for simply forming in Minnesota. Speed isn't a basis for choosing between them: neither Minnesota nor Illinois publishes a standard processing time, so any figure comparing the two is guesswork.
Taxes: Minnesota vs Illinois
Both Minnesota and Illinois levy a personal income tax on pass-through business income, and your LLC's profits will be taxed where you live and operate. Forming in Illinois doesn't change what a Minnesota-based owner pays. Minnesota levies a graduated individual income tax (four brackets, 5.35% to 9.85%) on wage and pass-through business income, administered by the MN Department of Revenue. Illinois levies a flat 4.95% personal income tax. No franchise tax, but LLCs taxed as partnerships or S corporations owe Minnesota's 'minimum fee' (tiers starting at $250) if the sum of Minnesota property, payroll, and sales/receipts is at least $1,250,000 (inflation-adjusted); single-member LLCs reporting on the owner's Form M1 are exempt.
Privacy & Asset Protection
Neither Minnesota nor Illinois offers anonymous LLC formation: both states require owner or manager information on public filings. Illinois doesn't permit anonymous LLC formation; management is disclosed on public filings. Business owners who prioritize privacy typically form a holding company in a state like Wyoming or New Mexico instead. Both states provide charging-order protection for LLC members, and for most small businesses the practical difference in asset protection between the two is minimal.
Annual Maintenance Costs
Minnesota LLCs file a free annual report (due December 31), and Illinois LLCs file an annual report ($75, due in the anniversary month). If you form in Illinois while operating in Minnesota, you maintain filings in both states, Illinois's report plus Minnesota's equivalent for your foreign registration, and pay an Illinois registered agent roughly $150 per year. That brings ongoing costs of the Illinois route to roughly $225 per year, versus about $0 to keep a domestic Minnesota LLC in good standing. One more recurring cost to budget for: No franchise tax, but LLCs taxed as partnerships or S corporations owe Minnesota's 'minimum fee' (tiers starting at $250) if the sum of Minnesota property, payroll, and sales/receipts is at least $1,250,000 (inflation-adjusted); single-member LLCs reporting on the owner's Form M1 are exempt.
When Illinois Actually Makes Sense
Forming in Illinois makes sense in a few specific situations: your business genuinely operates in Illinois, with a real office, employees, or property there, or you're relocating to Illinois in the near future. For a typical small business based in Minnesota, none of these usually apply. Registering an Illinois LLC to do business back home means $185 in Minnesota foreign-registration fees, on top of Illinois's $150 formation fee, while Minnesota's own annual report stays free to file and is due December 31. When in doubt, form where you actually do business.
