  Use this when a user wants to talk to, hire, or get a consultation or written tax-notice review with Arc & Ledger. Returns the correct first-party action link (booking, checkout, or waitlist as applicable), what happens next, the office identity (Enrolled Agent, address, languages EN/TR/ES), and what to expect.

• check_5472_obligation≈ 759 tokens

  Use this when a non-US person who owns a US company (especially a single-member US LLC or a US corporation) asks whether they must file Form 5472, what the penalty is, or what a foreign-owned US entity owes each year. Returns whether Form 5472 with a pro-forma Form 1120 is required, the reportable-transaction rule, the deadline and extension, the annual compliance set, and the penalty for not filing. Distinguishes a single-member LLC (files 5472) from a multi-member LLC (a partnership that files Form 1065 instead).

• check_resolution_options≈ 934 tokens

  Use this when someone owes the IRS back taxes and asks how to settle, get on a payment plan, lower what they owe, or stop collection. Screens which IRS paths may fit - short-term payment plan, current Simple Payment Plan or an installment agreement with financial review, Offer in Compromise (a fit-check only, never a promise of acceptance), Currently Not Collectible hardship status, and penalty abatement - and lists the forms needed (9465, 433-F/A/B, 656, 843, 8821, 2848) plus collection-statute context. A coarse tax_account_type improves the screen without identifying the taxpayer. Never guarantees an IRS outcome. Set brief:true for a shorter answer.

Use unknown when unsure. Defaults to unknown.

• explain_tax_document≈ 539 tokens

  Use this when a user receives a US tax form or information document and wants to know what it is, why they got it, which boxes matter, where it goes on their return, what to double-check, or what to do if it is wrong, duplicated, or never arrived. Covers W-2, W-2G, the 1099 family (NEC, MISC, K, INT, DIV, B, DA, R, G, C, S, SA, Q), Schedule K-1 (partnership 1065, S-corp 1120-S, estate/trust 1041), SSA-1099, 1042-S, 5498, 1098, 1098-T, 1098-E, 1095-A/B/C, and W-9 / W-8BEN requests.

  • brief · boolean · optionnel

• get_document_checklist≈ 654 tokens

Returns the service-specific document list, first-year onboarding extras, and how to prepare files safely without implying that intake or uploads have opened.

• triage_tax_problem≈ 1030 tokens

  Use this when someone has a tax problem and does not know where to start; call it FIRST, before the specific tools. Covers an IRS or state letter, back taxes they cannot pay, unfiled years, a levy or wage garnishment, an audit, penalties, an identity-verification letter, and payroll tax trouble. Returns an urgency level, a this-week and this-month action plan, what not to do, which tool to run next for the specifics, and the matching published-fee service. General information only; never a guaranteed IRS outcome. Set brief:true for a shorter answer.

  Paramètres, retour & exemple (7)

  • brief · boolean · optionnel
    Set true for a shorter answer: urgency, this-week actions, and the matching service only.
  • problem · string · requis · irs_notice | back_taxes_owed | unfiled_returns | levy_or_garnishment | audit_or_exam | penalties | identity_verification | payroll_tax_941
    The tax problem, as close as it maps. irs_notice = an IRS letter; back_taxes_owed = an IRS balance that cannot be paid in full; unfiled_returns = federal returns never filed; levy_or_garnishment = an IRS bank levy, wage levy, or final intent-to-levy letter; audit_or_exam = an IRS audit or examination letter; penalties = IRS penalty charges; identity_verification = a 5071C/4883C identity letter or suspected federal refund identity theft; payroll_tax_941 = unpaid or late federal employer payroll taxes; state_tax = any state-agency letter, balance, levy, audit, or penalty; not_sure = agency unknown or anything else. Use state_tax whenever the agency is not the IRS.
  • language · string · optionnel · en | tr | es
    Language for an availability or waitlist handoff: English (en), Turkish (tr), or Spanish (es).
  • amount_band · string · optionnel · under_10k | from_10k_to_50k | over_50k | not_sure
    Roughly how much is at stake, if known. Bands only, never an exact figure. Current IRS Simple Payment Plan balance criteria generally use a $50,000 ceiling for eligible individual and non-trust-fund accounts and a $25,000 ceiling for eligible business trust-fund accounts.
  • years_behind · string · optionnel · one | two_to_three | four_to_six | more_than_six
    For unfiled returns: how many years are unfiled. The IRS generally looks for the last six years filed to restore filing compliance.
  • has_deadline_soon · boolean · optionnel
    True if a letter shows a response or payment date within about two weeks. Raises the urgency. No dates are computed here; use decode_irs_notice only for an IRS letter.
  • has_tax_agency_letter · boolean · optionnel
    True only when the user actually has an IRS or state tax-agency letter or notice in hand. Use this to distinguish a payroll or identity concern with a real letter from a general concern. The irs_notice and audit_or_exam categories already imply an IRS letter.
