What is the Exit Tax in Japan?
Known in Japanese as 国外転出時課税制度, this is a tax regime that treats certain assets as if they were sold when a taxpayer gives up Japanese tax residency—or when those assets pass to someone who lives outside Japan. (nta.go.jp)
Who is Subject to It?
You are subject to this regime if you meet both the following:
- You are a “resident”: someone who has had domicile in Japan or lived there for so long, as defined under Japan’s tax law. Specifically, for the exit tax, your total domestic residence over the 10 years before exit must exceed a threshold (typically 5 years). (nta.go.jp)
- You hold “target assets” with unrealized gains whose fair market value exceeds JPY 100 million on the date of exit. Target assets include listed equities, investment trusts, derivatives, and unsettled transactions. (nta.go.jp)
Key Mechanics & Options
| Mechanism | Details |
|---|---|
| Deemed disposal | When you leave, assets are taxed as though sold, meaning you pay tax on gains even if you don’t physically sell. (nta.go.jp) |
| Tax deferral (“納税猶予” or paying later) | If you appoint a tax agent in Japan, provide sufficient security, and complete paperwork, you can defer payment for up to 5 years, with possible extension to 10 years. (nta.go.jp) |
| Return to Japan | If you come back within 5 (or for deferred cases, 10) years, and still hold the assets, you can cancel the deemed disposal via correction claim. (nta.go.jp) |
Compliance Checklist (Before Leaving Japan)
- Evaluate whether your target assets amount to JPY 100 million+ in market value.
- If yes, appoint a Japanese resident tax agent, file Notification of Tax Agent, with the tax office covering your location.
- Submit the required reports: the “report of foreign assets” by June 30 following Dec 31 prior to or at exit.
- If deferring payment, organize required security / guarantee (real estate pledge, guarantee insurance, etc.) and other paperwork.
Common Pitfalls & How to Avoid Them
- Under-estimating value: Mistakes in appraising securities or derivatives can lead to underreporting. Use recent market quotes and independent appraisals.
- Late agent appointment or missing agent notification: If you leave without appointing agent, or miss agent filing deadline, you cannot defer and may have to pay immediately.
- Assuming being non-resident exempts you automatically: Even after exit, foreign-source income may still trigger reporting or withholding obligations under treaties. Always check.
Practical Example
Suppose you’re a foreign national who’s lived in Tokyo for 7 years and hold:
- Listed equities worth JPY 80 million,
- Some options & forward contracts with unrealized gains of JPY 30 million,
- Totaling JPY 110 million in target assets.
If you depart Japan in 2026:
- Deemed sale of all assets -> taxed as income.
- If you arrange a tax agent & required security before departure, you may defer payment.
- If within the 5-year (or extended 10-year) period you return and still own the same assets, you can nullify the tax as though no exit sale occurred.
Exit-Related Deadlines & Updates
- The Self-Certification/foreign assets report is generally due June 30 for assets as of December 31 prior. (nta.go.jp)
- The system has not seen a major legislative change in the past 30 days; the rules have been stable since launch and through FY2026-tax revisions.
Why It Matters for Digital Nomads & Globally Mobile Expats
Many expats with global investment portfolios, or those frequently changing tax residence, underestimate the scope of the exit tax. If you live in Japan long enough, your temporary assets may come due when you leave. With proper planning—asset allocation, holding periods, deferral arrangements—this burden can be anticipated and managed.
