New Mexico LLC vs Wisconsin LLC (2026)
Written for owners based in New Mexico.
Verdict: for most owners, form where the business is based
Wisconsin sets its annual report deadline by calendar quarter rather than by date, so a company formed in February files by March 31 and one formed in October by December 31; the fee is $25 online or $40 on paper. Formation is $130 online against $170 by mail, and under 2025 Act 224 it is free where every member at formation is a student entrepreneur. New Mexico's single price is $50, with no report and no quarter to track. A Wisconsin LLC run from here also pays $100 to register.

Compare LLC Costs: New Mexico vs Wisconsin
New Mexico
Wisconsin
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
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 a standard turnaround (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, though New Mexico asks for nothing on the foreign-registration side, and pay a Wisconsin registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Wisconsin route to roughly $175 a 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.
