calculate_italian_tax
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 â¬85k cap) â 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 (0.40â0.86, 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 (0â1), used by
ordinario/impatriati. Ignored by forfettario.

compare_italian_regimes
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 (0.40â0.86); omit
for the professional-services default (0.78).
cost_ratio: Deductible costs as a fraction of revenue (0â1) for the
ordinario regimes.

list_tax_sources
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_sources
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 (1â12).
