Special Measures Act search + tax incentives + e-bookkeeping / invoice-system revision alerts. Stand up an in-firm RAG for 80 client engagements in 30 minutes.
Sized for a 5-person firm with ~80 SMB clients. Wire the MCP server into Claude Desktop or your in-house RAG and search across 35 tax rulesets, 9,484 laws, and 13,578 programs. Revision alerts keep e-bookkeeping (denshi-chobo), invoice-system (qualified-invoice), and consumer-protection law changes from slipping past you.
AutonoMath does not perform tax representation, tax document preparation, or tax consultation.
This service only provides information on publicly available tax incentive programs.
For specific tax judgments, please consult a 税理士 (Certified Public Tax Accountant).
NTA, MOF, e-Gov
tax_rulesets come from NTA primary documents; laws are e-Gov CC-BY; the Special Measures Act and related circulars are referenced at the article level. No aggregators (no second-hand sources). You can show the URL when explaining a position to a client.
Catch incompatible measures up front
Combinations like wage-increase promotion + SME investment promotion + DX investment promotion are encoded as 181 exclusion / prerequisite rules. Avoid the "filed in combination, denied later" failure mode.
e-bookkeeping, invoice-system, consumer-protection law
Register the articles you care about and receive revision, circular, and effective-date notifications by email. Monthly digest is free; real-time is ¥500/month. Designed to prevent filing-season incidents.
Feed industry, headcount, and planned investment, and the prescreen endpoint returns the top 5 (wage-increase promotion, SME investment promotion, DX investment, special depreciation). Have Claude Desktop call search_tax_incentives via MCP and produce a proposal that cites article numbers, expiration dates, and exclusion rules.
Look up an article like Article 42-12-5 (wage-increase promotion) and get its revision history. search_by_law reverse-resolves related programs (subsidies and tax incentives).
Register the articles you care about and the alert arrives. Examples: revisions to Article 7 of the e-bookkeeping law (electronic-transaction data retention), the extension of the 2-percent special invoice-system rule, transitional measures for qualified invoices. Each comes with the primary-source URL.
Drop a one-line <script> on the firm site to embed an "applicable special measures" search box. Standard ¥10,000/month (10,000 req included, with logo) or Whitelabel ¥30,000/month (30,000 req included, no logo). Visitors discover their own applicable measures, which converts to engagement.
When a client stacks a subsidy with a tax incentive, run combined_compliance_check to confirm "monozukuri subsidy + wage-increase promotion" doesn't trip the exclusion ruleset.
