Tools: assess_formation prepare_application get_application_status get_formation_contract compare_states explain_ein_route get_compliance_deadlines
assess_formation | Assess formation need without checkout. Anonymous. An SSN-shaped or ITIN-shaped field is refused and nothing is stored. params: goal, hasUsEntity, hasEin, jurisdictionKnown, selectedState, providerRequiresUsEntity, providerRequiresEin, foreignOwnedCaution, intendedEmail |
prepare_application | Prepare a provisional application and return the human claim URL. A human must claim and pay. This does not file, charge, or approve. An explicit operator request for existing formation assistance can attach a provisional non-actionable review to an eligible insufficient_information assessment. It does not recommend formation or start checkout. params: intendedEmail, assessmentId, assessment, operationId, operatorRequestsExistingFormationAssistance, assessmentOutcome, preparation |
get_application_status | Read redacted application status. Pass AgentGrant exactly as the HTTP route expects: Authorization bearer of the opaque application grant, not a Firebase ID token. params: applicationId*, AgentGrant* |
get_formation_contract | Return the live agent OpenAPI document. params: none |
compare_states | Read-only rows for Wyoming, Delaware, New Mexico, Florida, Texas, and California. Each row has the formation fee, the annual fee or report, franchise-tax notes, and the registered-agent requirement. Every figure has a government source URL and a retrieved date. This does not give legal advice, file, open an account, or take payment. params: none |
explain_ein_route | Read-only IRS EIN channels for whether the applicant has an SSN or ITIN and whether the principal business is in the United States, plus EIN.LLC's qualified timing. A principal business outside the United States is offered phone, fax, and mail only. It does not state another vendor's day count. It does not file or take payment. params: hasSsnOrItin*, principalBusinessInUs* |
get_compliance_deadlines | Read-only dated obligations. Form 5472 with pro forma Form 1120 is conditional on reportable transactions and entity status, not an automatic yearly filing for every foreign-owned SMLLC. Unknown transaction facts are unknown/needs-review. The $25,000 figure is the IRS failure-to-file penalty quote, plus the formation state's sourced annual report or franchise tax. It does not file. params: entityType*, ownerResidency*, formationState*, formationDate*, reportableTransactions, partVTransactions |
