Japan Input Credit Transition
Qualified Invoice System tracker for Japan — vendor registration numbers & the 80% → 50% non-qualified input-credit step-down
Under Japan's National Tax Agency (NTA) Qualified Invoice System (適格請求書等保存方式), a buyer takes a full consumption-tax input credit only on invoices from a registered qualified-invoice issuer. Purchases from non-registered suppliers qualify for a shrinking transitional share — 80% until 30 Sep 2026, then 50% from 1 Oct 2026, and 0% from 1 Oct 2029. This module classifies your vendors and computes the creditable and non-creditable tax on every bill.
Registration-number validation
Vendor and company registration numbers (登録番号) are validated as T + 13 digits using the real NTA Corporate Number (法人番号) check-digit algorithm, so mistyped numbers are rejected before a bill is posted. Each supplier is automatically classed qualified or non-qualified.
Per-bill input-credit split
Every vendor bill and refund is split into creditable and non-creditable consumption tax using the transitional share in force on the bill date. The phase (qualified / 80% / 50% / none) is stored on the move for reporting and audit.
Period summary & review
A period-summary wizard aggregates creditable versus non-creditable tax across any date range, broken down by transition phase. A scheduled job and a posting warning surface non-qualified purchases that carry a non-deductible portion so finance can chase registration numbers ahead of the 1 Oct 2026 step-down.
Qualified-invoice business rules
Issued customer invoices can be validated against the Japanese qualified-invoice rule set (registration number, 10% / 8% reduced-rate consumption-tax breakdown, JPY currency) built on the shared e-invoice engine.
Compatibility
Supports Odoo 18 and Odoo 19 (Community & Enterprise). All classification and calculation runs locally in your database; no data is transmitted to the NTA or any third party. Verifying that a registration number is currently active against the NTA public lookup remains your responsibility.
