Agentic toolkit for accounting & tax workflows. First service: an interview-driven Portuguese IRS intake that profiles a client and routes them to classic.tax/intake, plus Modelo 3 filing guidance, e-Fatura reconciliation, and a tax reviewer.
Interview a prospective client to capture their IRS profile + income data, then hand them a paste-ready summary and the https://www.classic.tax/intake link (or submit directly on request). Optionally pass the client's name as argument.
Guided Portuguese IRS (Modelo 3) filing workflow for one taxpayer or household. Optionally pass a taxpayer NIF or year as argument (e.g. /agentic-accounting:irs-file 2025).
Reconcile a taxpayer's e-Fatura invoices against the IRS deduction buckets and flag pending/misclassified invoices before filing. Provide the e-Fatura export (CSV/JSON/table) or a path to it.
Reconcile a Portuguese taxpayer's e-Fatura invoices against the IRS deduction buckets (general family expenses, health, education, housing, lares, sector-VAT incentive) and flag pending, unclassified, or miscategorized invoices before filing Modelo 3. Use when reviewing e-Fatura data, classifying invoices into deduction categories, or estimating deductions à coleta.
Conversationally interview a prospective Portuguese IRS client to capture their full profile and income data, validate it against the Classic Tax lead-intake schema, and finish by either handing them a paste-ready summary plus the https://www.classic.tax/intake link, or submitting directly to the intake API. Use whenever onboarding a new client, collecting intake/profiling data, "filling the intake", or building a lead profile for IRS filing.
Portuguese personal income tax (IRS) filing via Modelo 3 — who must file, income categories (A–H), the full anexo catalog and how to select them, residency rules, the April–June filing window, deductions à coleta, and special regimes (IRS Jovem, IFICI/ex-NHR, IRS automático). Use whenever preparing, reviewing, or explaining a Portuguese IRS / Modelo 3 declaration, selecting anexos, or reasoning about Portuguese personal income tax.
