DJP moves all tax administration into Coretax from July 2026
The Directorate General of Taxes announced that Coretax becomes the core system for the entire tax administration process — supervision, enforcement, collection, and objections and appeals are moving into the single system in stages.
Key points
- Coretax becomes the core system for the whole tax administration process, starting July 2026.
- Supervision, law enforcement, collection, and the settlement of objections and appeals move into the system in stages.
- DJP's stated aim is governance and transparency: work previously handled on documents outside the main system is to be done inside Coretax.
- DJP reported tax invoice volume for the same tax period up 4.62% year on year as of July 2026.
What this means for Japanese companies
If your filings, objections, or audit correspondence are handled by a local staff member or an outside consultant, the audit trail now lives in Coretax rather than in their inbox. Confirm who holds your Coretax access, that their authority is properly registered, and that your accounting records reconcile to what is filed in the system.
