It does not respond to individual circumstances and is not a substitute for advice from a licensed tax professional (税理士). Always verify against primary sources.
| Tool | Pricing | Returns |
|---|---|---|
list_tax_rules | Free | Rule catalog, filterable by category / taxpayer / tax_year (resolves the applicable epoch) |
get_tax_rule | Free | One rule in full: statement, exceptions, statutory citations, sources |
get_tax_parameters | Free | Tax-rate tables and thresholds with sources (income brackets, 20.315% breakdown, filing threshold) |

The paid tool genuinely fulfills: a settled x402 payment returns the rule pack itself, not a placeholder.
