About these tools
All calculators are free, work entirely in your browser (no data sent to servers), and are updated for the 2026 tax year (Reiwa 8) including the December 2024 tax reform (basic deduction increase, salary income deduction increase).
Results are estimates. Your actual tax depends on your municipality, age, family structure, and various deductions. For official advice, consult a Japanese tax accountant (税理士) or your local tax office (税務署).
