Illinois LLC vs New Mexico LLC (2026)
Written for owners based in Illinois.
Verdict: for most owners, form where the business is based
New Mexico requires no annual or biennial report, so the $50 formation fee is the whole Secretary of State cost, against $225 in a first Illinois year and $75 annually after. It also keeps members off the public record. The absence of a report removes the yearly prompt: a company that quietly loses its registered agent can be administratively revoked with no missed filing to warn you, and New Mexico no longer publishes a fee schedule on its public site. Registering that LLC in Illinois still costs $150.

Compare LLC Costs: Illinois vs New Mexico
Illinois
New Mexico
A figure shown as "from" is the least the state can charge, not a price. Tennessee's report is $300 for up to six members and $50 for each member above six, its franchise tax is the greater of $100 or 0.25% of Tennessee net worth, Wyoming's report is the greater of $60 or $.0002 per dollar of in-state assets, Kentucky's entity tax is $175 up to $3 million of gross receipts and graduated above it, and New York's annual filing fee is graduated on New York source gross income. A total that contains one of those is shown as "from" for the same reason. 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 the state publishes a rate for it, and any one-time registration charge a state requires before the LLC may trade. Two exclusions follow from that wording. Arizona and Nebraska require publication and publish no rate, so no newspaper cost is carried for either and their totals are not the whole cost. Alaska's $50 annual state business licence is a separate charge from the Secretary of State fees and is not carried here either. 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. 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 New Mexico charges $50. New Mexico is $100 cheaper upfront. The cost that usually gets overlooked: if you form in New Mexico but operate in Illinois, you must also register as a foreign LLC in Illinois (a $150 filing) and maintain a registered agent in New Mexico (typically around $150 per year). That puts the realistic first-year cost of the New Mexico route at roughly $350, versus $150 for simply forming in Illinois. Speed isn't a basis for choosing between them: neither Illinois nor New Mexico publishes a standard processing time, so any figure comparing the two is guesswork.
Taxes: Illinois vs New Mexico
Both Illinois and New Mexico 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 New Mexico 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
New Mexico allows anonymous LLC formation. Member and manager names don't appear on routine public filings. New Mexico's Articles of Organization require only the organizer and registered agent, and LLCs file no annual report, so members and managers stay off public filings. 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 New Mexico 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 New Mexico LLCs file no annual report at all. If you form in New Mexico while operating in Illinois, you maintain filings in both states, New Mexico asks for no report, but Illinois still wants its equivalent for your foreign registration, and pay a New Mexico registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the New Mexico route to roughly $225 a year, versus about $75 to keep a domestic Illinois LLC in good standing.
When New Mexico Actually Makes Sense
Forming in New Mexico makes sense in a few specific situations: you need anonymous ownership. Illinois puts owner or manager information on public filings and New Mexico doesn't (usually via a holding company, since operating in Illinois still requires a public foreign registration there), your business genuinely operates in New Mexico, with a real office, employees, or property there, or you're relocating to New Mexico in the near future. For a typical small business based in Illinois, none of these usually apply. Registering a New Mexico LLC to do business back home means $150 in Illinois foreign-registration fees, on top of New Mexico'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.
