get_llc_feesread-onlyReturns one US state's LLC formation fee, its recurring annual-report or franchise-tax cost and cadence, online processing time, and known gotchas such as publication requirements, plus a labeled list of the official state source URLs the figures were taken from (dataset verified 2026). Use when the user asks what it costs to form or keep an LLC in a specific state. Covers all 50 states + DC.
compare_llc_costsread-onlyRanks US states by LLC cost: the one-time formation fee, the recurring state fee, or the first-year total (formation plus one recurring period). Use when the user asks which state is cheapest to form or maintain an LLC in, or wants LLC costs compared across specific states. Covers all 50 states + DC. State fees only — registered-agent fees, service fees, and revenue-based taxes are excluded. Retur
get_annual_report_deadlineread-onlyCalculates when an LLC's next annual report or franchise tax is due in a given state and the amount owed, and returns the state's rule text, late-filing consequences where the dataset has them (penaltyAndNotes), and the official state source URLs. Use when the user asks when their LLC's annual report is due, how often it is filed, or what happens if it is late. States that key the deadline to the
check_llc_nameread-onlyScreens a proposed business name against state naming rules. It does NOT search any state registry and cannot tell whether a name is already taken. Wyoming and Delaware: the entity designator where the statute requires one (such as "LLC"), words that are restricted or need agency approval (such as "Bank"; in Wyoming also "Trust" or "University"), and other state-specific rules. Florida: the requir
list_filing_statesread-onlyLists FilingDesk's coverage: the states it files formations in today with all-in prices, the states its naming-rule screen supports, and fee/deadline data coverage (all 50 states + DC). Use when the user asks which states FilingDesk can file in, or before stating that FilingDesk can file in a particular state.
compare_formation_optionsread-onlyReturns fixed, factual tradeoffs for deciding WHERE to form (topic "state": the home state versus Wyoming, Delaware, and Nevada, including the cost of foreign-qualifying back into the home state) or WHAT entity type to use (topic "entity_type": LLC versus the S-corp tax election versus C-corp), plus a required disclaimer. Deliberately not a recommendation: the options are meant to be presented neu
preview_orderread-onlyValidates and prices a formation order and returns the exact summary that would be submitted, WITHOUT submitting anything (no side effects). Use when the user wants FilingDesk to form their LLC or corporation and has provided the business name, state, entity type, and their name, email, and phone. The returned summary is meant to be shown to the user verbatim, and this step is required before subm
submit_ordercan modifySubmits a formation order to FilingDesk. THIS HAS A REAL-WORLD EFFECT: it records the order, notifies a FilingDesk specialist, and may send an automatic order-confirmation email to the customer's email address. The specialist then reviews the order, confirms name availability and the price, and emails a payment link. Nothing is charged at submission. Call only after preview_order, once the user ha
