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. |
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. |
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. |
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. |
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. |
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. |
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. |
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. |
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. |
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. |
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. |
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. |
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. |
