Did the Pension Office Cheat Me? Understanding the 20.42% Tax Withholding

If you received your Japan Lumpsum Pension refund and the amount was less than you expected, you're not alone — many workers assume something went wrong. Here's what's really happening, explained by a licensed Japanese tax accountant.

❌ MYTH: "I only received about 80% of my Lumpsum Pension payout. I got cheated."

⭕ FACT: You were NOT cheated. The missing 20.42% was withheld as national income tax — and you can claim it back!

When the Japan Pension Service approves your Lumpsum Pension (Dattai Ichijikin), they transfer 79.58% directly to your overseas bank account. The remaining 20.42% is automatically withheld as Japanese income tax.

Under Japanese tax law, you have the legal right to claim a tax refund for this withheld 20.42% by filing an income tax return through a designated Tax Agent (納税管理人) in Japan.We can become your official Tax Agent in Japan.
