Tax Reporting for International Money Transfers from Japan
Answer Box
Key rule: Sending money abroad is NOT taxable. However, if your overseas assets exceed 50 million yen at year-end, you must file an Overseas Asset Report (国外財産調書). Banks automatically report transfers over 1 million yen to tax authorities.
Reporting Thresholds
| Situation | Threshold | Action Required |
|---|---|---|
| Single transfer | Over 1 million yen | Bank auto-reports to authorities (no action by you) |
| Overseas assets total | Over 50 million yen at Dec 31 | File Overseas Asset Report by March 15 |
| Overseas income | Any amount | Report on tax return if Japanese tax resident |
| Gift to overseas person | Over 1.1 million yen/year | Gift tax may apply |
What Is Reported Automatically
When you send over 1 million yen in a single international transfer, your bank or remittance service files a notification (国外送金等調書) with the tax office. This is informational — it does not mean you owe tax. The tax office uses this to cross-check your declared income and assets.
Overseas Asset Report (国外財産調書)
Who Must File
If your total overseas assets (bank accounts, real estate, investments, etc.) exceed 50 million yen on December 31, you must file this report by March 15 of the following year.
Penalties for Non-Filing
- Underreported income found with unreported overseas assets: additional 5% penalty tax
- Intentional non-filing: up to 1 year imprisonment or 500,000 yen fine
Common Misconceptions
- "Sending money home is taxable" — No, the transfer itself is not income or a taxable event
- "Small transfers are invisible" — Cumulative patterns may trigger inquiries even under 1 million
- "I don't earn income abroad so I don't need to report" — Asset reporting is separate from income reporting
Q: Will sending money trigger a tax audit?
Not automatically. The report is routine. However, if your transfer amounts are inconsistent with your declared income, the tax office may send an inquiry letter.
Q: Do I need to report cryptocurrency transfers?
Cryptocurrency gains are taxable as miscellaneous income in Japan. Transferring crypto abroad does not avoid this obligation. Report all gains on your tax return.
