## What is Japan’s Exit Tax?
Japan’s *国外転出時課税制度* (“exit-on-departure tax”) applies when certain residents—those who own **“対象資産”** (target assets)—cease Japanese residence, e.g., when moving abroad, and have assets worth over **¥100 million**. The system treats unrealized capital gains on such assets as if they were sold on the departure date, triggering income tax and “special income tax for reconstruction.”([nta.go.jp](https://www.nta.go.jp/taxes/shiraberu/shinkoku/kokugai/01.htm?utm_source=openai))
## Who Is Subject to It?
- Japanese **residents of five years or more** who own **over ¥1億 (100 million yen)** in specified financial assets at the time of leaving.([nta.go.jp](https://www.nta.go.jp/taxes/shiraberu/shinkoku/kokugai/01.htm?utm_source=openai))
- The target assets include **securities, derivatives**, and some other financial instruments.([nta.go.jp](https://www.nta.go.jp/taxes/shiraberu/shinkoku/kokugai/01.htm?utm_source=openai))
## Key Features & Practical Impacts
- There’s a **deemed realization** (i.e., treated as if sold) on the day of exit for taxation purposes.
- For those who also transfer assets via **gift or inheritance** to non-residents, the “exit tax” system still applies to deemed gains.([nta.go.jp](https://www.nta.go.jp/taxes/shiraberu/shinkoku/kokugai/01.htm?utm_source=openai))
- A **tax payment deferral** is possible if the taxpayer files proper paperwork and provides **security**, though interest and restrictions apply.([nta.go.jp](https://www.nta.go.jp/taxes/shiraberu/shinkoku/kokugai/01.htm?utm_source=openai))
## Strategies for Risk Mitigation
- **Asset valuation timing**: If your assets are close to ¥100 million, tracking valuation as of departure date matters. Keep good documentation.
- **Pro-rate ownership**: Partial ownership, partnerships—understanding what counts as “owning” within the legal definitions helps.
- **Gift vs. sale before exit**: Transferring assets before exit to Japanese relatives may trigger different rules—but this is one of the system’s triggers.
- **Use of deferral**: If you qualify and provide collateral, you may defer the payment until after your exit—if you later return within 5–10 years (depending on extended deferrals) and still own assets, you might cancel the exit tax via correction or return.([nta.go.jp](https://www.nta.go.jp/taxes/shiraberu/taxanswer/shotoku/1478.htm?utm_source=openai))
## Case Example
**Scenario**: A long-term Japanese resident owns ¥120 million in listed foreign equities with unrealized gains of ¥30 million. They plan to move to Australia next year.
- The “exit tax” triggers a deemed sale of the equities on date of exit.
- They must report gains on that amount (¥30 million) in Japan, paying income tax and reconstruction tax.
- If they qualify, they may apply for deferral by providing guarantor or collateral. If they return within 5 years and still own the assets, they may file to cancel the tax.
## Actionable Checklist
| Step | Why it Matters | What You Should Do Now |
|---|---|---|
| Audit your holdings | Know whether total assets cross the ¥100 million threshold | Prepare documents & valuations of all assets |
| Review residency status | Long residence triggers more rules | Assess residence duration & plan exit timing |
| Document costs & base values | Needed to compute gains | Maintain records of purchase, currency effects |
| Consult NTA & legal advisers | Rules are technical and the deferral process strict | File required forms, apply for deferral if needed |
Exit tax can represent a major liability for high-net-worth individuals planning to relocate. **Knowing the rules, applying deferment options, and planning ahead can save you from large unexpected tax bills**.
