## What Changed Under the FY 2026 Tax Reform
- **Blue Return Special Deduction**: To qualify for the full deduction under the blue return system in income tax, taxpayers — including expats — must now **file their blue return special deduction claim electronically using e-Tax** and submit financials like balance sheets and profit & loss statements by the standard deadline.

- **Deduction Amount Raised**: The maximum for blue return special deduction has been increased from the previous amount (around ¥550,000) to **¥650,000**, effective for income earned in **fiscal years from April 1, 2027 (令和9年)** onward.

## What Expats Should Know (Case Examples)
- **Example 1 – Freelance Designer from UK**: If you’re running a graphic design business in Tokyo and earn business income, to get the full ¥650,000 blue return deduction you need to:
1. Use e-Tax to file
2. Prepare a balance sheet and P&L statement
3. Ensure all accounting records (including invoices) are maintained per Japanese standards
Failing (2) or (1) reduces your deduction significantly.
- **Example 2 – Part-time English Teacher from USA**: Teaching income streams may be mixed with salaried work. If your total business income is low (< around ¥10-15 million), blue return election remains attractive — but only if you are ready to fulfil the stricter filing requirements.
## Practical Planning Tips
- **Set up accounting now**: Even if your next fiscal year starts after April 2027, bookkeeping and financial statements need to be accurate and ready.
- **Move to electronic filing (e-Tax)**: If you still file paper-based, switch before FY 2027 to avoid missing the full deduction.
- **Review eligibility thresholds**: If your business income is large, evaluate whether staying under thresholds (e.g. revenue, asset size) might keep you eligible without triggering higher compliance burdens.
- **Stay informed on the similar items**: Other special deductions (住居ローン控除, etc.) have had expansions and changes under the same reform package. ([mof.go.jp](https://www.mof.go.jp/tax_policy/tax_reform/outline/fy2026/08taikou_gaiyou.htm?utm_source=openai))
## Key Takeaways for Expats
- The reform’s stricter requirements **increase compliance** but also offer better tax savings for fully compliant taxpayers.
- If you plan to use the blue return deduction, start improving your accounting systems now.
- Consult a tax advisor familiar with both Japanese tax law and your home country’s tax treaty (if any).
