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

Compare LLC Costs: Illinois vs Iowa
Illinois
Iowa
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
Illinois charges $150 to form an LLC, while Iowa charges $50. Iowa is $100 cheaper upfront. The cost that usually gets overlooked: if you form in Iowa but operate in Illinois, you must also register as a foreign LLC in Illinois (a $150 filing) and maintain a registered agent in Iowa (typically around $150 per year). That puts the realistic first-year cost of the Iowa route at roughly $350, versus $150 for simply forming in Illinois. Speed isn't a basis for choosing between them: neither Illinois nor Iowa publishes a standard processing time, so any figure comparing the two is guesswork.
Taxes: Illinois vs Iowa
Both Illinois and Iowa 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 Iowa doesn't change what an Illinois-based owner pays. Illinois levies a flat 4.95% personal income tax. Neither state imposes a separate franchise or privilege tax on LLCs beyond standard filing fees.
Privacy & Asset Protection
Iowa allows anonymous LLC formation. Member and manager names don't appear on routine public filings. Iowa requires no member or manager names on the Certificate of Organization or the biennial report; only the organizer and registered agent are public. Illinois doesn't offer that same privacy. Illinois doesn't permit anonymous LLC formation; management is disclosed on public filings. 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. One important caveat: if you register your Iowa LLC as a foreign LLC in Illinois, that Illinois registration is itself a public record, which can undercut much of the privacy benefit for a business that operates in Illinois.
Annual Maintenance Costs
Illinois LLCs file an annual report ($75, due in the anniversary month), and Iowa LLCs file a biennial report ($30, due April 1, every two years). If you form in Iowa while operating in Illinois, you maintain filings in both states (Iowa's report plus Illinois's equivalent for your foreign registration) and pay an Iowa registered agent roughly $150 per year. That brings ongoing costs of the Iowa route to roughly $255 per year, versus about $75 to keep a domestic Illinois LLC in good standing.
When Iowa Actually Makes Sense
Forming in Iowa makes sense in a few specific situations: you need anonymous ownership. Illinois puts owner or manager information on public filings and Iowa doesn't (usually via a holding company, since operating in Illinois still requires a public foreign registration there), your business genuinely operates in Iowa, with a real office, employees, or property there, or you're relocating to Iowa in the near future. For a typical small business based in Illinois, none of these usually apply. Registering an Iowa LLC to do business back home means $150 in Illinois foreign-registration fees, on top of Iowa's $50 formation fee, while Illinois's own annual report runs $75 a year and is due in the anniversary month. When in doubt, form where you actually do business.
