Is it cheaper to form an LLC in Wisconsin than New Mexico?

No. Wisconsin costs more upfront ($130 vs $50), and if you operate in New Mexico you must also register there as a foreign LLC ($100) plus pay a Wisconsin registered agent. Realistic first-year cost is roughly $380 versus $50 for forming locally.

Can I form my New Mexico business in Wisconsin?

Yes. Any New Mexico business can form its LLC in Wisconsin. But if the business operates in New Mexico, it must also register there as a foreign LLC ($100 filing fee) and maintain a registered agent in Wisconsin, so you take on two states' fees and filings instead of one.

Does Wisconsin have better asset protection than New Mexico?

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

New Mexico charges $50 to form an LLC, while Wisconsin charges $130. New Mexico is $80 cheaper upfront. The cost that usually gets overlooked: if you form in Wisconsin but operate in New Mexico, you must also register as a foreign LLC in New Mexico (a $100 filing) and maintain a registered agent in Wisconsin (typically around $150 per year). That puts the realistic first-year cost of the Wisconsin route at roughly $380, versus $50 for simply forming in New Mexico. 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: New Mexico vs Wisconsin

Both New Mexico and Wisconsin 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 Wisconsin doesn't change what a New Mexico-based owner pays. Neither state imposes a separate franchise or privilege tax on LLCs beyond standard filing fees.

Privacy & Asset Protection

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

Annual Maintenance Costs

New Mexico LLCs file no annual report at all, and Wisconsin LLCs file an annual report ($25, due in the anniversary quarter). If you form in Wisconsin while operating in New Mexico, you maintain filings in both states, Wisconsin's report plus New Mexico's equivalent for your foreign registration, and pay a Wisconsin registered agent roughly $150 per year. That brings ongoing costs of the Wisconsin route to roughly $175 per year, versus about $0 to keep a domestic New Mexico LLC in good standing.

When Wisconsin Actually Makes Sense

Forming in Wisconsin makes sense in a few specific situations: your business genuinely operates in Wisconsin, with a real office, employees, or property there, or you're relocating to Wisconsin in the near future. For a typical small business based in New Mexico, none of these usually apply. Registering a Wisconsin LLC to do business back home means $100 in New Mexico foreign-registration fees, on top of Wisconsin's $130 formation fee, while New Mexico itself never asks for an annual report at all. New Mexico already allows anonymous formation, so the privacy argument for Wisconsin doesn't apply to a New Mexico-based owner. Trading New Mexico's no-annual-report status for Wisconsin's filing calendar is a step backwards for most owners. When in doubt, form where you actually do business.

Frequently Asked Questions

: 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.
: New Mexico, for most. Forming where you operate keeps costs and compliance simple. Wisconsin is worth considering only if you actually do business there or have investor requirements that point there.
: 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. Only 19 of the 50 states publish anything about non-expedited turnaround at all. Whichever you pick, remember that forming in Wisconsin while operating in New Mexico means you're not fully set up until the New Mexico 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.
