Verdict: Wisconsin wins for most businesses
For most Wisconsin-based businesses, forming locally in Wisconsin is the smarter choice. You avoid paying fees in two states and managing compliance in both. New Mexico 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: Wisconsin vs New Mexico
Wisconsin
New Mexico
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
Wisconsin charges $130 to form an LLC, while New Mexico charges $50. New Mexico is $80 cheaper upfront. The cost that usually gets overlooked: if you form in New Mexico but operate in Wisconsin, you must also register as a foreign LLC in Wisconsin (a $100 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 $300, versus $130 for simply forming in Wisconsin. Only one side of this comparison is knowable: Wisconsin publishes instant on receipt (online), while New Mexico publishes no standard processing time, so the two can't be ranked against each other on speed.
Taxes: Wisconsin vs New Mexico
Both Wisconsin 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 a Wisconsin-based owner pays. 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. Wisconsin doesn't offer that same privacy. Wisconsin's annual report lists member/manager names and addresses, which become public. 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 Wisconsin, that Wisconsin registration is itself a public record, which can undercut much of the privacy benefit for a business that operates in Wisconsin.
Annual Maintenance Costs
Wisconsin LLCs file an annual report ($25, due in the anniversary quarter), and New Mexico LLCs file no annual report at all. If you form in New Mexico while operating in Wisconsin, you maintain filings in both states, New Mexico's report plus Wisconsin's equivalent for your foreign registration, and pay a New Mexico registered agent roughly $150 per year. That brings ongoing costs of the New Mexico route to roughly $175 per year, versus about $25 to keep a domestic Wisconsin 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. Wisconsin puts owner or manager information on public filings and New Mexico doesn't (usually via a holding company, since operating in Wisconsin 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 Wisconsin, none of these usually apply. Registering a New Mexico LLC to do business back home means $100 in Wisconsin foreign-registration fees, on top of New Mexico's $50 formation fee, while Wisconsin's own annual report runs $25 a year and is due in the anniversary quarter. When in doubt, form where you actually do business.
