Jp Crypto Tax Rules tools (4)

write = sends, deletes, buys or posts
  • get_rule_packFree

    Scenario-curated bundle of full structured rules (statements, citations, parameters) for one use case: defi_staking | overseas_exchange | corporate_holding | transition_2028. Paid via x402: each call costs 0.05 USDC. This tool returns the HTTP 402 payment challenge (spec-conformant accepts list) for the pack resource. The 402 is real: settle it against /v1/packs/{scenario} with an X-PAYMENT header and the 200 response delivers the full pack body ({status:"settled", settlement, pack}) — payment buys the actual structured rules, not a receipt. Not tax advice. 一般的な税制情報の提供であり、個別の税務判断は税理士にご相談ください。

  • get_tax_parametersFree

    FREE — returns structured tax parameters with per-value sources: progressive income tax brackets, resident tax and reconstruction surtax figures, the 2028-reform separate-taxation rate and loss-carryforward years, and the salary-filer filing threshold. Approximate reference values from public sources; not tax advice. 一般的な税制情報の提供であり、個別の税務判断は税理士にご相談ください。

  • get_tax_ruleFree

    FREE — returns one full structured rule: statement, exceptions, status, effective dates, machine tags and statutory citations (sources), served verbatim from the versioned rules corpus. Not tax advice. 一般的な税制情報の提供であり、個別の税務判断は税理士にご相談ください。

  • list_tax_rulesFree

    FREE — returns structured rules. Catalog of machine-readable Japanese crypto-asset tax rules (rules-as-code): titles, status (current / enacted_pending), effective dates and statutory citations, filterable by category, taxpayer and tax_year. tax_year resolves the current-vs-2028-reform epoch per rule (applies / pending_enforcement). Sources are public only (NTA FAQ, e-Gov statutes, MOF documents); not tax advice. 一般的な税制情報の提供であり、個別の税務判断は税理士にご相談ください。

From the Jp Crypto Tax Rules repository's README, as published. We do not edit it. Read it on GitHub

JP Crypto Tax Rules — MCP Server

Remote MCP server exposing machine-readable rules-as-code for Japanese crypto-asset taxation to AI agents — structured rules with statutory citations, tax parameters, and the current-vs-2028-reform transition logic. Built from public sources only.

  • MCP endpoint (Streamable HTTP, stateless): https://jp-crypto-tax-rules-62ko7b2uwa-an.a.run.app/mcp
  • Machine index: llms.txt · API contract: openapi.yaml
  • Sibling gateways: jp-m2m-mcp (corporate records) · jp-biz-opportunity-mcp (tenders & subsidies)

Not tax advice. This is general tax-system information served as structured rules with citations. 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.

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

No API key and no initialize handshake required. USDC on Base (testnet during the current private beta).

Scope & sources

  • Epochs: current regime (miscellaneous income, total-average / moving-average cost basis, through FY2027 returns) and the FY2026 reform (20.315% separate taxation, 3-year loss carryforward) marked enacted_pending until the enforcement date is fixed.
  • Sources: 国税庁 暗号資産FAQ (令和7年12月版), the relevant 所得税法 / 法人税法 / 消費税法 provisions via e-Gov, and the 令和8年度税制改正大綱. Every rule carries its own citations.
  • Status: closed private beta. Rules, scope and pricing may change. Source of the gateway lives in a private repository; this repo hosts the public MCP documentation and registry manifest.
