Japan Consumption Tax Return

Prepare the NTA consumption-tax (消費税) return worksheet inside Odoo, with full qualified-invoice input-credit aggregation

What this module does

Japanese businesses file a consumption-tax final return with the National Tax Agency (NTA). This module assembles that return worksheet from your posted Odoo invoices and bills, computes every reported figure as the NTA expects under the qualified-invoice system, and produces a worksheet file you transcribe into the official return or import into your own e-Tax software. It covers general taxation, simplified taxation (deemed purchase rate) and the 20% special measure, handling both the standard 10% and reduced 8% rates split into national and local components.

Qualified-invoice input credit

  • Extraction factors 7.8/110 and 6.24/108
  • Registered qualified issuer (full credit) vs non-registered supplier split
  • Transitional ratio: 80% to 2026-09-30, 50% to 2029-09-30
  • Registration number (T + 13 digits) validation with NTA check digit

Output tax, simplified & 20% special measure

  • Standard 10%, reduced 8%, zero-rated and exempt buckets; base rounded down to 1,000 yen
  • Local consumption tax as 22/78 of the national tax
  • Deemed purchase rates 90/80/70/60/50/40% by business type; 50,000,000 yen ceiling
  • 20% special measure for eligible new registrants, one-click method switch, validation report

BYOK boundary: this module prepares the return figures and the worksheet file inside your own database. It performs no transmission to the NTA and holds no e-filing accreditation. Odoo 18 and 19, Community and Enterprise; builds on the standard account module only.
