Is it cheaper to form an LLC in Illinois than Delaware?

No. Illinois costs more upfront ($150 vs $110), and if you operate in Delaware you must also register there as a foreign LLC ($200) plus pay an Illinois registered agent. Realistic first-year cost is roughly $500 versus $110 for forming locally.

Can I form my Delaware business in Illinois?

Yes. Any Delaware business can form its LLC in Illinois. But if the business operates in Delaware, it must also register there as a foreign LLC ($200 filing fee) and maintain a registered agent in Illinois, so you take on two states' fees and filings instead of one.

Does Illinois have better asset protection than Delaware?

Not meaningfully. Both states provide charging-order protection for LLC members, and neither offers a decisive asset-protection edge for a typical small business. Sound insurance and clean separation of business and personal finances matter more in practice.

Will you operate outside your home state?

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

Delaware charges $110 to form an LLC, while Illinois charges $150. Delaware is $40 cheaper upfront. The cost that usually gets overlooked: if you form in Illinois but operate in Delaware, you must also register as a foreign LLC in Delaware (a $200 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 $500, versus $110 for simply forming in Delaware. Speed isn't a basis for choosing between them: neither Delaware nor Illinois publishes a standard processing time, so any figure comparing the two is guesswork.

Taxes: Delaware vs Illinois

Both Delaware 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 Delaware-based owner pays. Illinois levies a flat 4.95% personal income tax. Delaware LLCs owe a flat $400 annual LLC tax (no report required).

Privacy & Asset Protection

Delaware, your home state, actually offers more formation privacy than Illinois: Delaware allows anonymous LLC formation, while Illinois requires owner or manager information on public filings. 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. From a privacy standpoint there's no reason for a Delaware-based business to form in Illinois.

Annual Maintenance Costs

Delaware LLCs file no annual report at all, and Illinois LLCs file an annual report ($75, due in the anniversary month). If you form in Illinois while operating in Delaware, you maintain filings in both states, Illinois's report, though Delaware asks for nothing on the foreign-registration side, and pay an Illinois registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Illinois route to roughly $225 a year, versus about $400 to keep a domestic Delaware LLC in good standing. The tax inside those totals: Delaware LLCs owe a flat $400 annual LLC tax (no report required).

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 Delaware, none of these usually apply. Registering an Illinois LLC to do business back home means $200 in Delaware foreign-registration fees, on top of Illinois's $150 formation fee, while Delaware itself never asks for an annual report at all. Delaware already allows anonymous formation, so the privacy argument for Illinois doesn't apply to a Delaware-based owner. Trading Delaware's no-annual-report status for Illinois's filing calendar is a step backwards for most owners. When in doubt, form where you actually do business.

: Not meaningfully. Both states provide charging-order protection for LLC members, and neither offers a decisive asset-protection edge for a typical small business. Sound insurance and clean separation of business and personal finances matter more in practice.
: Delaware, for most. Forming where you operate keeps costs and compliance simple. Illinois is worth considering only if you actually do business there or have investor requirements that point there.
: Speed isn't a basis for choosing between them: neither Delaware nor Illinois publishes a standard processing time, so any figure comparing the two is guesswork. Only 19 of the 50 states publish anything about non-expedited turnaround at all. Whichever you pick, remember that forming in Illinois while operating in Delaware means you're not fully set up until the Delaware foreign registration is also processed, so the out-of-state route is rarely the faster path end to end. If your timing is genuinely fixed, buy the state's expedite tier rather than relying on a standard turnaround.
