How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| decode_irs_notice Use when a user provides the code from an IRS notice or letter and wants a general explanation, the usual response window, or the next procedural step. Do not request the notice itself or any taxpayer identifier. | unknown | unknown | unknown |
| check_resolution_options Use to screen general IRS payment and collection alternatives from a rough balance, filing-compliance status, ability-to-pay category, and coarse tax-account type when known. This is an educational fit screen, not a promise that the IRS will approve an option. | read | false | unknown |
| estimate_irs_penalty Use to estimate selected federal failure-to-file, failure-to-pay, and underpayment amounts from nonidentifying figures. The result is an estimate and does not replace an IRS account transcript. | unknown | unknown | unknown |
| explain_tax_document Use when a user names a US tax form or information document and wants to understand its purpose, common fields, or usual return treatment. Do not request or accept the document itself. | unknown | unknown | unknown |
| deadline_calendar Use to return common federal filing and payment dates for a selected filer or entity type. The user must verify the date for weekends, holidays, extensions, fiscal years, and special facts. | unknown | unknown | unknown |
| check_fbar_fatca Use to screen general FBAR and Form 8938 thresholds from aggregate balance, filing status, residence, and account-count facts. Do not request account numbers, institution names, or statements. | read | false | unknown |
| check_treaty_withholding Use to explain general US withholding rules, documentation, and supported US-Turkey treaty rates for a payment category. Treaty eligibility and source rules depend on the full facts. | unknown | unknown | unknown |
| check_itin_eligibility Use to screen general ITIN reason categories, whether a return is commonly attached, and supporting-document requirements. Never request or process an actual ITIN, passport, or identity document. | unknown | unknown | unknown |
| check_5472_obligation Use to screen common Form 5472 triggers for a foreign-owned US disregarded entity or corporation. The result is a general filing screen and does not prepare or file the form. | unknown | unknown | unknown |
| estimate_quarterly_taxes Use to estimate federal quarterly tax payments from nonidentifying income, entity, withholding, and prior-year tax figures. Return the assumptions, safe-harbor context, and due dates. | unknown | unknown | unknown |
| estimate_accountable_plan Use to estimate potentially reimbursable business expenses under an accountable-plan scenario, including the split 2026 business-mileage rates. The result does not establish a plan or determine substantiation. | unknown | unknown | unknown |
| estimate_augusta_rule Use to screen the fewer-than-15-days home-rental rule under IRC 280A(g) and calculate conditional amounts. Keep the owner-side income exclusion separate from the business-side requirements for ordinary and necessary use and reasonable rent. | unknown | unknown | unknown |
| estimate_rental_income Use to estimate a basic rental-income result from nonidentifying figures and identify the modeled depreciation, passive-loss, and personal-use limitations. | unknown | unknown | unknown |
