💡 Key Points
- The lump-sum withdrawal payment is a scheme that lets foreign nationals claim back a portion of the pension premiums they paid when they leave Japan, but 20.42% of the payout amount is withheld as income tax at source.
- Because of the retirement income deduction and the mechanism of taxing only half the amount, filing a refund return often results in nearly all of this 20.42% being refunded (some tax may apply depending on the payout size).
- Filing a refund return requires appointing a tax administrator before leaving Japan, and if one is not appointed, it may become impossible to file a refund return afterward.
- The payment rate for the lump-sum withdrawal increases with the number of months enrolled — the Employees' Pension caps out at 60 months (payment rate 5.5), while the National Pension can be received without any withholding tax.
Why Financial Optimization Matters
The Lump-sum Withdrawal Payment (Dattai-ichijikin) lets foreigners claim back part of their paid pension contributions on leaving Japan. But 20.42% is withheld as income tax at source, so without action, over 20% disappears. Example: ¥1M payment → ¥204K withheld → ¥796K take-home.
Take-home Calculation Formula
For Employees' Pension Insurance (Kosei-nenkin):
- Payment rate = Employees' Pension premium rate 18.3% × 1/2 × tier number, rising with months enrolled (36 months = 3.3; cap 60 months = 5.5; FY2026)
- 2021 reform: cap raised 36→60 months (5 years)
- Average monthly remuneration ¥300K, 36 months → payment = ¥300K × 3.3 = ~¥990K, ~¥202K withheld → ~¥788K take-home
- After refund filing → nearly all withholding (~¥202K) refunded → Final ~¥990K
- [Cap example] Average monthly remuneration ¥250K, 60 months (5-year cap) → payment = ¥250K × 5.5 = ~¥1.375M, ~¥281K withheld → retirement income deduction ¥2M > ¥1.375M so ¥0 tax → after refund nearly all returned → final ~¥1.375M
National Pension (Kokumin-nenkin) payments are smaller (FY2026 premium ¥17,920 → max ~¥538K at 60 months, no withholding).
How to File for the 20.42% Withholding Refund
The lump-sum is taxed as "retirement income," qualifying for the retirement income deduction (¥400K per year, minimum ¥800K), and only half of the amount above the deduction is taxable. For most cases up to about 5 years of enrollment, the payment falls within the deduction, so taxable retirement income is ¥0 and nearly all of the 20.42% withheld is refunded. The refund amount depends on your enrollment period and payment size; higher average remuneration or longer enrollment can leave some tax due.
⚠️ You must designate a Tax Manager (Nōzei Kanrinin) before departure.
Tax Manager Designation Steps
- Before departure, find someone living in Japan (family/friend/tax accountant)
- Submit "Tax Manager Notification for Income Tax/Consumption Tax" to your local tax office
- Depart → Apply for lump-sum withdrawal (can be done from abroad) → Receive payment in 4–6 months
- The next year, Feb 16–Mar 15: tax manager files refund return on your behalf
- Refund arrives 1–2 months later to tax manager's account → Remit to you via Wise
Enrollment Period Strategy
- Payment rate jumps in tiers (6/12/18...). If close to the next tier, delaying 1–2 months raises the payment rate and can gain you roughly ¥100K–¥300K
- Kosei-nenkin pays multiples more than Kokumin-nenkin; leave Japan while employed for max benefit
Remittance Optimization
- Bank wire ¥1M → fees + FX spread ~¥25K cost
- Wise → ~¥6–8K fee + real exchange rate
- SBI Remit → ¥980 fee + FX spread varies by country
Hire a Tax Accountant?
- National Pension only / small amount → DIY (or via tax manager)
- Kosei-nenkin, ¥0 tax within the deduction → a tax manager can handle it (free–~¥50K)
- High average remuneration with tax due / complex income → recommend hiring a tax accountant (¥50K–¥150K)
- Choose firms billing themselves "for foreigners" or "international tax"
Frequently Asked Questions (FAQ)
I forgot to appoint a tax manager and already left Japan. Can I still file for a refund?
In principle, you can still appoint a tax manager after returning to your home country, but the process becomes more complicated and raises the risk of missing the filing deadline (within 5 years). If possible, always complete this procedure before leaving Japan. In some cases you can also mail the tax manager notification form from overseas (check with the tax office).
After receiving the lump-sum withdrawal payment, can I come back to Japan and work again?
Yes, that's possible. However, once you receive the lump-sum withdrawal payment, that period will not count toward your future pension enrollment period. Even if you start paying into the pension again after returning to Japan, the past period will not be restored — please keep this in mind.
How many years do I have to file the refund claim?
You can file within 5 years starting from January 1 of the year following the year you received the lump-sum withdrawal payment. For example, if you received it in 2026, you can file the refund claim until December 31, 2031. The sooner you do it, the lower the risk.
I have permanent residency but am leaving Japan. Can I still receive the lump-sum withdrawal payment?
Yes, as long as you do not hold Japanese nationality. Even permanent residents are eligible if their nationality is foreign. However, since receiving it will substantially reduce your pension if you return to Japan in the future, permanent residents should consider carefully.
I already left Japan several years ago. Can I still go back and claim it now?
The lump-sum withdrawal payment must be claimed within 2 years of leaving Japan. The refund claim must be filed within 5 years of receiving the payment. If more than 2 years have passed since departure, the lump-sum withdrawal payment itself can no longer be claimed.
Both my spouse and I are foreign nationals. Does each of us receive a lump-sum withdrawal payment?
Yes, both of you are eligible. Payments are made separately based on each person's own pension enrollment record. A tax manager must also be appointed separately for each of you.
Can tax accountant fees be claimed as an expense in my home country?
It depends on your home country's tax system. In many countries, 'tax accountant fees related to Japanese pension procedures' are not eligible for tax deduction — please confirm with your home country's tax authority or a tax accountant.
