📋Step-by-Step Guide

Determine if you need to file

If your employer handles year-end adjustment (年末調整), you may not need to file separately. You must file if you have multiple income sources, income over ¥20M, or freelance/side income over ¥200,000.

Understand your resident status for tax

Residents in Japan for 1+ year are taxed on worldwide income. Non-residents (less than 1 year) are only taxed on Japan-sourced income.

💡 팁: Tax treaties exist with many countries — check if your country has one with Japan to avoid double taxation.

Gather your documents

Collect income statements (源泉徴収票), receipts for deductible expenses (medical costs, charitable donations), and your My Number.

File using e-Tax or at the Tax Office

Filing period: February 16 – March 15. Use the National Tax Agency's e-Tax portal (English available) or visit your local tax office.

💡 팁: freee and other tax software can simplify the process with English support.

Pay any additional tax or receive a refund

If you overpaid through withholding, you'll receive a refund. Additional tax owed must be paid by the March 15 deadline.

💡Helpful Tips

✓Japan has tax treaties with over 70 countries — check to avoid double taxation.
✓The Furusato Nozei (hometown tax) system allows you to donate to municipalities and claim deductions.
✓Medical expenses over ¥100,000/year are deductible.
✓Use freee or yayoi cloud software for easier filing with English support.
