How to Get Your Japan Pension Refund Without Losing 20.42%

Information current as of March 2026 based on the Japan Pension Service and the National Tax Agency.

The Japan pension refund is really a two-step process. First, you claim the official Lump-sum Withdrawal Payment. Then, if your payout came from Employees’ Pension Insurance, you deal with the separate Japan pension tax refund step so the 20.42% withholding does not become a permanent loss.

I also work in legal affairs in Japan, and this is exactly the kind of procedure that looks easy online but goes wrong because one step happens before departure, one after departure, and one at a different office entirely. When I lived in the UK, even basic admin became hard because I did not know the local sequence of steps. The problem was not that the system did not exist. It was access to the right step at the right time.

Should you claim the refund or keep your pension credits?

Before you claim anything, decide whether taking the money now is actually the right move.

According to the Japan Pension Service, you can claim if you are non-Japanese, have at least 6 months of coverage, are no longer covered, file within 2 years after you no longer have an address in Japan, and are not already entitled to a pension. The same JPS guide says that if your eligibility period is 120 months or more, you cannot claim the lump-sum at all.

This is where many people rush. If you claim while still under 120 months, the JPS English guide says all Japanese pension coverage periods before the claim are invalidated, even though the payment amount itself is capped at 60 months. That is why the payout often feels much lower than the total amount you remember being deducted from salary.

• Claim now if you are clearly below 10 years, do not expect to build Japanese eligibility later, and want the cash rather than future pension rights.
• Pause and calculate if you are near the 10-year line. As of March 2, 2026, the JPS social security agreement status page shows 24 agreements in force; however, the United Kingdom, South Korea, China, and Italy are dual-coverage only, not totalization agreements. If your home country does totalize with Japan, your Japanese months may still help you qualify for a future pension instead of a lump-sum.
• Do not claim blindly if you are already at or above 120 months of eligibility, or if totalization may push you there. In that situation, the lump-sum route can disappear, but future pension rights may become valuable.

One more important nuance: if you left Japan on a re-entry permit, the JPS guide says you can still claim after departure if you filed your moving-out notice. If you did not file that notice, you are generally treated as still insured until the permit expires.

Before you leave Japan: 4 things to set up first

This is the part most people skip, and it is the part that protects the withheld 20.42%.

1. File your moving-out notice at city hall. Do this before departure so your residence record is deleted properly. Useful phrase: 「転出届を出したいです」 (Tenshutsu todoke o dashitai desu) — I would like to file a moving-out notice.
2. Choose your tax agent before you fly. The NTA says your tax representative can be a person who resides in Japan or a Japanese corporation. The JPS guide also says there is no special qualification beyond having an address or residence in Japan, but filing before departure is much cleaner than fixing it later. Useful phrase at the tax office: 「納税管理人の届出をしたいです」 (Nozei kanrinin no todokede o shitai desu) — I would like to submit a tax agent notification.
3. Keep your pension-number documents and banking proof. JPS asks for documents showing your Basic Pension Number, plus bank details proving the account belongs to you. Take clear photos or scans before you pack anything, because the JPS guide notes you will need your pension number again for later inquiries.
4. Use the current form, not an old PDF from a blog. JPS changed the foreign-language claim form on February 3, 2025 because overseas remittance rules now require items such as the SWIFT/BIC code and fuller address details. Decide now where your payment notice will be sent overseas and how you will courier the original to your tax agent after it arrives. If you are stuck on who can realistically act as your tax agent, ask on LO-PAL.

One more practical point: the tax office for the refund step is based on your last Japanese address, not your agent’s address. The NTA is clear on that, so write it down before you leave.

How to file the lump-sum claim after departure

Once you are abroad and no longer have a Japanese address, the claim itself is fairly mechanical if you prepared well.

1. Download the current claim form and sample. Use the official JPS lump-sum page, which links the latest multilingual PDF, Excel form, and example.
2. Attach the required documents. The JPS guide lists a passport copy, documents showing you no longer have an address in Japan, bank verification, and your Basic Pension Number Notice or Pension Handbook. If you filed your moving-out notice before leaving, JPS says it can usually confirm the deleted address record itself, so separate proof of no Japanese address may not be needed.
3. Mail the package to JPS. The official mailing address is: Japan Pension Service (Foreign Business Group), 3-5-24 Takaido-Nishi, Suginami-ku, Tokyo 168-8505, Japan, as shown in the JPS guide PDF. Use tracked mail and keep a full copy of what you sent.
4. Watch for two separate results. First, the money is remitted to your designated account. Around the same stage, JPS also mails the original notice you will need for the tax-refund step.

If you need to check status in English, the JPS multilingual consultation page lists 0570-05-1165 for Japan and +81-3-6700-1165 from overseas for pension benefits and lump-sum withdrawal questions.

Recent foreign-resident discussions show the same pattern. One former JET shared in a Reddit thread, “I filed mid-August, got my main payment late December and my 20% tax refund last week.” In another thread, a user said the refund “took nearly a year” until a status call revealed it had not been processed. Individual experiences vary, but the lesson is consistent: use tracked mail, keep copies, and follow up if the timeline drifts.

How to get back the 20.42% tax and avoid delays

This is the step that turns a basic lump-sum claim into a full tax representative Japan pension refund plan.

For Employees’ Pension Insurance, the NTA says 20.42% is withheld when the lump-sum is paid to a non-resident. For National Pension, the JPS guide says income tax is not withheld at source, so there is usually no second refund step for that part.

• Step 1: Wait for the original JPS notice. JPS says it sends the original payment-determination notice when the lump-sum is remitted. Do not throw it away.
• Step 2: Send the original notice to your tax agent in Japan. The NTA guidance specifically requires the notice when filing the tax return through your tax agent.
• Step 3: Have your tax agent file with the tax office for your last Japanese address. The filing route described in the NTA and the JPS guide is the return for refund due to taxation on retirement income at the taxpayer’s option. If you did not register the tax agent before departure, JPS says the notification can still be submitted together with the tax return.
• Step 4: Track the separate deadline. The NTA refund-return rule generally allows filing up to 5 years from January 1 of the year following the payment year. That is longer than the pension claim deadline, but waiting is still risky if documents go missing.

In practice, many people try to recover all or most of the withheld amount through this step, but your exact result depends on the tax calculation and filing details. What matters for this article is simpler: if you skip the tax-agent setup or lose the original notice, you make recovery much harder than it needs to be.

To avoid delays, send the original notice promptly, keep scans of everything, and make sure your tax agent knows the correct tax office. If status stalls, the agent should contact the competent tax office or use the NTA consultation contacts for guidance. And if you miss the usual February-March tax season, remember that a refund return follows its own rule; our guide on missed tax-return deadlines in Japan explains the basic logic.
