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

Massachusetts charges $500 to form an LLC, while South Dakota charges $150. South Dakota is $350 cheaper upfront. The cost that usually gets overlooked: if you form in South Dakota but operate in Massachusetts, you must also register as a foreign LLC in Massachusetts (a $500 filing) and maintain a registered agent in South Dakota (typically around $150 per year). That puts the realistic first-year cost of the South Dakota route at roughly $800, versus $500 for simply forming in Massachusetts. Speed isn't a basis for choosing between them: neither Massachusetts nor South Dakota publishes a standard processing time, so any figure comparing the two is guesswork.

Taxes: Massachusetts vs South Dakota

South Dakota has no personal income tax while Massachusetts does, but forming your LLC in South Dakota won't change that. LLC profits pass through to you and are taxed where you live and operate (in Massachusetts), not where the LLC is registered, so a South Dakota LLC offers no income-tax savings for a Massachusetts-based business. Massachusetts taxes wage and pass-through income at 5.0%, plus a 4% surtax on taxable income above the inflation-adjusted threshold ($1,107,750 for tax year 2026). No separate franchise or excise tax on LLCs taxed as partnerships/disregarded entities, but the mandatory $500 annual report fee is among the highest in the nation.

Privacy & Asset Protection

Neither Massachusetts nor South Dakota offers anonymous LLC formation: both states require owner or manager information on public filings. South Dakota's annual report confirms the LLC's ownership/management each year on the public record. Business owners who prioritize privacy typically form a holding company in a state like Wyoming or New Mexico instead. 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.

Annual Maintenance Costs

Massachusetts LLCs file an annual report ($500, due in the anniversary month), and South Dakota LLCs file an annual report ($55, due in the anniversary month). If you form in South Dakota while operating in Massachusetts, you maintain filings in both states, South Dakota's report plus Massachusetts's equivalent for your foreign registration, and pay a South Dakota registered agent roughly $150 per year. That brings ongoing costs of the South Dakota route to roughly $705 per year, versus about $500 to keep a domestic Massachusetts LLC in good standing. One more recurring cost to budget for: No separate franchise or excise tax on LLCs taxed as partnerships/disregarded entities, but the mandatory $500 annual report fee is among the highest in the nation.

When South Dakota Actually Makes Sense

Forming in South Dakota makes sense in a few specific situations: your business genuinely operates in South Dakota, with a real office, employees, or property there, or you're relocating to South Dakota in the near future, which would also move you out of Massachusetts's personal income tax. For a typical small business based in Massachusetts, none of these usually apply. Registering a South Dakota LLC to do business back home means $500 in Massachusetts foreign-registration fees, on top of South Dakota's $150 formation fee, while Massachusetts's own annual report runs $520 a year and is due in the anniversary month. When in doubt, form where you actually do business.
