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. (mof.go.jp)

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)

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).
