## Key Compliance Changes from Latest Reforms
Recent tax reforms under FY2026 include several procedural and compliance reforms with practical implications:
- **Updated tax forms and system upgrades**: The National Tax Agency will overhaul its tax system on **September 24, 2026**, changing the formats for various tax return, filing, and reporting documents. Paper forms will shift to white-and-black print, and the use of earlier color or printed control copies (“控用”) may be eliminated.

- **Stricter rules for electronic record‐keeping and blue-return special deduction eligibility**: To claim the ¥650,000 or higher blue return deductions, taxpayers must maintain their books using electronic systems and preserve transaction records as electronic records per the law’s special rules.

- **Document retention period extended**: For retirement‐related payments like one-time elderly retirement sums (“老齢一時金”), the retention period for the declaration document increases to **10 years** (previously 7 years).

## Why These Changes Matter
- These compliance changes can impact audit risk. Missing or non-electronic records may result in disqualification of special deductions or heavier penalties.
- Those making paper filings may need to update their processes ahead of September changes to avoid form rejection or delay.
- Long maintenance of documents ensures consistency should any exit tax, pension, or retirement income claim be audited many years later.
## Checklist for Compliance
- **System readiness by Sept 24, 2026**: Ensure that your accounting software and workflows can produce the new forms correctly. If using external preparers, confirm they’re up-to-date.
- **Electronic bookkeeping**: Keep transaction logs, totals, receipts in formats allowed under Japanese law. Use approved electronic systems or scanning methods.
- **Retain retirement income documents** for at least 10 years.
- **Record all international work ties** if you're a nomad or have overseas income, especially for residency status and source determination.
## Example Scenario
A small consulting firm under the blue return scheme uses traditional paper ledgers. Under revised rules, to continue claiming the special blue return deduction, they must maintain ledgers in electronic form and preserve electronic records. Failure to do so could lead to loss of deductible benefits.
Similarly, Ms. B, who receives a “老齢一時金” in 2027, must keep her declaration documents until **10 years** after payment to comply with the new retention rule.
## Take-Home Advice
- Audit your record-keeping processes now. Transition early.
- Coordinate with your tax preparers/software vendors to ensure correct forms starting Sept 2026.
- Establish a document management policy that addresses long-term retention.
- Confirm eligibility—and maintain quality—of electronic records to sustain deduction claims.
