Compare LLC Costs: Connecticut vs New Mexico

Filing Fees & Formation Costs

Connecticut charges $120 to form an LLC, while New Mexico charges $50. New Mexico is $70 cheaper upfront. The cost that usually gets overlooked: if you form in New Mexico but operate in Connecticut, you must also register as a foreign LLC in Connecticut (a $120 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 $320, versus $120 for simply forming in Connecticut. Only one side of this comparison is knowable: Connecticut publishes a standard turnaround (most online filings auto-accepted), while New Mexico publishes no standard processing time, so the two can't be ranked against each other on speed.

Taxes: Connecticut vs New Mexico

Both Connecticut 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 Connecticut-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. Connecticut doesn't offer that same privacy. Connecticut's annual report discloses the LLC's members or managers, a public filing. 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 Connecticut, that Connecticut registration is itself a public record, which can undercut much of the privacy benefit for a business that operates in Connecticut.

Annual Maintenance Costs

Connecticut LLCs file an annual report ($80, due March 31), and New Mexico LLCs file no annual report at all. If you form in New Mexico while operating in Connecticut, you maintain filings in both states, New Mexico asks for no report, but Connecticut 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 $230 a year, versus about $80 to keep a domestic Connecticut 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. Connecticut puts owner or manager information on public filings and New Mexico doesn't (usually via a holding company, since operating in Connecticut 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 Connecticut, none of these usually apply. Registering a New Mexico LLC to do business back home means $120 in Connecticut foreign-registration fees, on top of New Mexico's $50 formation fee, while Connecticut's own annual report runs $80 a year and is due March 31. When in doubt, form where you actually do business.
