How to Claim Your Japan Pension Lump-Sum Withdrawal and Tax Refund

If you contributed to Japan’s pension system for at least six months and have left the country, you can claim the Japan pension lump-sum withdrawal (脱退一時金) by mailing an application to the Japan Pension Service within two years of your departure. The payment refunds a portion of your National Pension or Employees’ Pension Insurance contributions, but accepting it permanently erases those coverage months from your record, which can cost you future pension rights at home or on any return to Japan.

Who Can Claim

You qualify only if all of the following are true:

You are not a Japanese national.
You contributed to the National Pension or Employees’ Pension Insurance for six months or more.
You have canceled your residential registration (転出届) and left Japan.
You have fewer than ten years of total coverage. Ten years or more makes you eligible for the regular old-age pension instead, which disqualifies you from the lump-sum route.¹
You have never received disability or survivor benefits from the Japanese pension system.

The two-year clock starts the day you leave Japan. File after that and the right is gone.²

How Much You Get

The amount depends on which system you paid into and how many months you contributed.

Employees’ Pension Insurance

If you were enrolled through a Japanese employer, your payment is your average standard remuneration (roughly your average monthly salary, including bonuses and overtime) multiplied by a rate tied to your months of coverage:

6–11 months: 0.5
12–17 months: 1.1
18–23 months: 1.6
24–29 months: 2.2
30–35 months: 2.7
36–41 months: 3.3
42–47 months: 3.8
48–53 months: 4.4
54–59 months: 4.9
60 months or more: 5.5

Someone who averaged ¥300,000 a month for three years (36 months) would receive about ¥300,000 × 3.3 = ¥990,000 before tax.

National Pension

Self-employed workers and others who paid the flat National Pension contribution (¥17,920 a month in fiscal year 2026) receive a smaller lump sum calculated on a similar bracket structure tied to that flat rate.³ Because the contributions themselves are much lower, so is the payout.

The 2026 Cap Increase

Through March 2026, the formula caps your months at 60 no matter how long you actually contributed. Seven years of work gets treated as five. From April 1, 2026, the cap rises to 96 months (eight years) under the pension reform tied to the new Ikusei Shuro work program.⁴ The rate brackets for months 61 through 96 had not been published at the time of writing, but longer-tenure workers should see meaningfully larger payouts once the expanded table is in force.

Documents to Gather Before You Leave

Assemble everything on this list while you are still in Japan. Chasing paperwork from overseas adds months of delay.

Your Basic Pension Number Notice (基礎年金番号通知書), or your Nenkin Techo pension handbook if you enrolled before April 2022. Either shows the pension number the application needs.⁵
Passport copies: the identification page and the page showing your Japanese departure stamp.
Bank documentation from an account outside Japan showing your name, account number, and SWIFT/BIC code.
The Lump-Sum Withdrawal Payment Claim Form, available on the Japan Pension Service website and at any JPS branch, listing both your former Japanese address and your current overseas address.

Check that the romanization of your name on the bank documents matches your pension record character for character. Name mismatches are one of the most common reasons a payment gets rejected.

The Departure Stamp Trap

Using an automated gate at the airport means no departure stamp in your passport, and the Japan Pension Service will not accept a claim without proof you left. The fix is simple if you plan for it: at the automated gate on your final departure, ask the officer standing there to stamp your passport before you walk on. If you already left, a family member in the same household can bring the passport back to your original port of departure and request a retroactive stamp; the Immigration Services Agency lists pension paperwork as a recognized reason.⁶ Otherwise, you can request a formal disclosure of your immigration record from the agency, which takes considerable time.

Filing and Payment Timeline

Mail the completed package to the Japan Pension Service after you have left Japan. The claim cannot be filed while a Japanese residential registration is still active.² Processing usually runs three to six months, longer if your contribution history or documents raise questions. All correspondence goes to the overseas address on your form, so make sure that address will still receive mail months later.

When the claim is approved, JPS sends a Notice of Payment confirming the amount and wires the money to your foreign account. Keep the original Notice of Payment. You need it to recover the tax that was withheld.

The 20.42% Tax Withholding and How to Get It Back

Employees’ Pension lump-sum payments are hit with a 20.42% income tax withholding at source, a figure that includes the 2.1% reconstruction surcharge in effect through 2037.⁷ On a ¥990,000 payment, roughly ¥202,000 disappears before the money reaches you.

Most of it is recoverable, but only through a separate process that starts before you leave. You must appoint a Tax Agent (納税管理人) who lives in Japan. The agent does not need to be a tax professional; a trusted friend or former colleague can do it, provided they are comfortable visiting a tax office and handling paperwork in Japanese. File the Tax Agent Declaration Form (納税管理人の届出書) at the tax office covering your last Japanese address before departure.

Once your Notice of Payment arrives, send the original to your Tax Agent. The agent files an income tax return at the local tax office to claim the refund, which is deposited into their Japanese account and then transferred to you.⁷ There are transfer fees and delays, but the recoverable amount is large enough to be worth the trouble.

You have five years from January 1 of the year after payment to file the refund claim. Miss that deadline and the withheld amount stays with the Japanese government.

Should You Even Claim It? Totalization Trade-offs

Japan has social security agreements with roughly two dozen countries, including the United States, Germany, France, Canada, and Australia.⁸ Under most of them, Japanese contribution periods can be combined with your home country’s record to meet minimum eligibility thresholds. For Americans, that means Japanese pension months can count toward qualifying for U.S. Social Security.⁹

Once you accept the lump-sum payment, the coverage periods used to calculate it are permanently erased from your Japanese record and cannot be totalized with your home country’s system.¹⁰ The Japan Pension Service itself warns applicants to “consider well” before choosing between a one-time payment and future annual pension benefits.

Do the arithmetic. If you worked in Japan for four years and those 48 months would push you across a qualifying threshold at home, cashing out ¥1.5 million now could cost you decades of monthly pension payments later. The lump sum makes clean sense for people who are young, contributed briefly, or already have ample credits in their home system. If you are anywhere near a qualifying line, get advice before you file.

One boundary worth knowing: the agreements with the United Kingdom, South Korea, China, and Italy cover only the elimination of dual coverage, not totalization of contribution periods. If your home country is one of those four, claiming the lump sum sacrifices no totalization benefit because the benefit does not exist under your country’s agreement.⁸

What If You Return to Japan

There is no way to repay the lump sum and restore your prior coverage. If you take the payment and later come back to work in Japan, your pension record starts from zero.¹⁰ New contributions accumulate fresh, but the earlier months are gone. That matters most for people who eventually spend ten or more years in Japan across multiple stints and would have qualified for the old-age pension had those first years stayed on the books.

U.S. Tax Reporting for Americans

U.S. citizens and green card holders owe U.S. tax on worldwide income, and the Japanese lump-sum payment is not an exception. The IRS treats foreign pension distributions as taxable even without a Form 1099, with the taxable amount generally being the gross distribution minus your cost basis (contributions made from after-tax income).¹¹

The U.S.–Japan tax treaty says pensions paid to a resident of either country are taxable only in the country of residence.¹² In principle, that means a U.S. resident should owe tax only to the United States. In practice, Japan withholds 20.42% at source regardless, which is exactly why filing the Japanese refund through your Tax Agent matters: you avoid paying twice on the same money. Any Japanese tax you cannot recover can generally be claimed as a foreign tax credit on your U.S. return.

If the amounts involved are significant, a tax professional who works in cross-border pensions is worth what they cost. The interaction of the withholding, the Japanese refund, and the U.S. return has enough moving parts to justify the fee.
