  • calculate_italian_taxCompute exact Italian tax for one regime at a given annual revenue.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Compute exact Italian tax for one regime at a given annual revenue. Deterministic calculation (not an estimate): substitute/income tax, INPS social contributions, net income, and effective rate. `breakdown.eligible` is False when the regime doesn't apply to the inputs (e.g. forfettario above the €85k cap) — present that as "not eligible", not as a real option. Args: revenue_eur: Gross annual revenue in EUR. regime: One of `forfettario_5`, `forfettario_15`, `ordinario`, `ordinario_impatriati`. coefficient: Forfettario coefficiente di redditività (0.40–0.86, set by the activity's ATECO group). Omit for the professional-services default (0.78). Ignored by non-forfettario regimes. cost_ratio: Deductible costs as a fraction of revenue (0–1), used by ordinario/impatriati. Ignored by forfettario.

  • compare_italian_regimesCompare all Italian regimes side by side at one revenue level.No findings

    Why it is in this group

    • The name "compare_italian_regimes" says "compare": a word for reading.
    Description, as the server wrote it
    Compare all Italian regimes side by side at one revenue level. Runs forfettario (5% & 15%), ordinario, and ordinario + impatriati through the deterministic engine and returns them sorted by net income (best first), each with its full breakdown and eligibility. Args: revenue_eur: Gross annual revenue in EUR. coefficient: Forfettario coefficiente di redditività (0.40–0.86); omit for the professional-services default (0.78). cost_ratio: Deductible costs as a fraction of revenue (0–1) for the ordinario regimes.

    Why it is in this group

    • The name "list_tax_sources" says "list": a word for reading.
    Description, as the server wrote it
    List the primary sources the corpus can search, and what each covers. Use this to discover the valid `sources` filter values for `search_italian_tax_sources` and to understand the corpus's coverage.

  • search_italian_tax_sourcesSearch TaxCompass's primary-source corpus and return passages to cite.No findings

    Why it is in this group

    • The name "search_italian_tax_sources" says "search": a word for reading.
    Description, as the server wrote it
    Search TaxCompass's primary-source corpus and return passages to cite. Hybrid semantic + keyword retrieval over Italian tax & company-law primary sources: Normattiva (statute), Agenzia delle Entrate (circolari & guidance), INPS (social security), pinned tax-year tables (IRPEF brackets, INPS rates, forfettario thresholds & coefficienti di redditività), the ATECO 2025 code catalogue, and EU/treaty sources. Each result carries a `chunk_id`, `source`, and (usually) a `url`. Cite the `url` and quote the `text`; do not assert Italian tax facts the passages don't support. Queries work in any language, but Italian keywords improve recall against the (Italian) legal corpus. Args: query: What to search for. Keyword-dense Italian phrasing works best. sources: Optional subset to restrict to (see `list_tax_sources` for keys). Omit to search everything. Unknown keys are ignored. k: Max passages to return (1–12).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
