What is the retirement income taxation election?

When you receive an Employees' Pension lump-sum withdrawal payment after leaving Japan, 20.42% is automatically withheld from it. Filing the retirement income taxation election (退職所得の選択課税) lets the tax be recalculated the way it would be for a resident of Japan — and whatever was overpaid comes back.

Why is 20.42% taken in the first place?

For tax purposes the lump-sum payment is classified as retirement income. A person living in Japan who receives retirement income gets a large retirement income deduction, which cuts the tax sharply. But by the time the lump-sum is paid you have already left Japan and are a non-resident, so the deduction is not applied and a flat rate (20.42%) is withheld up front instead. The withholding is not a mistake — it is the standard treatment for non-residents.

What changes when you file the election?

Filing the retirement income taxation election recalculates the tax from scratch as if you were a resident of Japan, applying the retirement income deduction. The difference between the 20.42% withheld and the recalculated tax is what can be refunded.

The retirement income deduction grows with the length of service (enrolment). So even with a short enrolment period, as is typical for a lump-sum withdrawal, the recalculated tax is often nil or very small up to a certain amount. That gap is the refund.

How much comes back?

In most cases almost all of the withheld tax is refunded, but a full refund is not guaranteed. The actual amount depends on:

• your Employees' Pension enrolment period
• whether you received other retirement income in the same year
• the outcome of the tax office's review

An accurate estimate requires the withheld amount printed on your payment decision notice, so an individual preliminary check is the reliable way to find out.

How it is filed

The election is filed with a Japanese tax office. A non-resident cannot easily deal with the tax office in person, so a Japanese tax accountant is normally appointed as tax agent to file on your behalf. That is covered in What is a tax agent?

This article explains how the scheme is structured; it does not calculate any individual's expected refund. Whether a refund is possible, and how much, requires an individual review based on your payment decision notice.
