Tax Invoice Credit Context

A background context loader for Japan's invoice system input tax credit rules, specifically the 仕入税額控除 requirements under the shinkoku tax filing plugin. This isn't user-invocable. Claude pulls it automatically when answering questions about claiming input tax credits. It walks through the basic two-part requirement (qualified invoices plus ledger), checks against the six permanent ledger-only exceptions like public transit and vending machines, explains the transitional credit rates for purchases from tax-exempt businesses (80% stepping down to zero), and covers the three deduction methods based on taxable sales ratio. If you're building tax tools for Japanese businesses navigating the invoice system transition, this gives Claude the structural knowledge to answer credit eligibility questions without users needing to invoke anything manually.
