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

Oregon charges $100 to form an LLC, while Illinois charges $150. Oregon is $50 cheaper upfront. The cost that usually gets overlooked: if you form in Illinois but operate in Oregon, you must also register as a foreign LLC in Oregon (a $275 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 $575, versus $100 for simply forming in Oregon. Speed isn't a basis for choosing between them: neither Oregon nor Illinois publishes a standard processing time, so any figure comparing the two is guesswork.

Taxes: Oregon vs Illinois

Both Oregon 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 an Oregon-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

Neither Oregon 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

Oregon LLCs file an annual report ($100, due in the anniversary month), and Illinois LLCs file an annual report ($75, due in the anniversary month). If you form in Illinois while operating in Oregon, you maintain filings in both states, Illinois's report plus Oregon'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 $325 per year, versus about $100 to keep a domestic Oregon LLC in good standing.

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 Oregon, none of these usually apply. Registering an Illinois LLC to do business back home means $275 in Oregon foreign-registration fees, on top of Illinois's $150 formation fee, while Oregon's own annual report runs $100 a year and is due in the anniversary month. When in doubt, form where you actually do business.
