Overseas Remittances and Tax: The Reporting Rules to Know

01The tax office sees overseas remittances

The first thing to know is that there is a mechanism by which overseas remittances above a certain amount are reported by financial institutions to the tax office. The idea that "it's overseas, so they won't know" does not hold.

Caution
The remittance itself is not taxed, but depending on the nature of the funds (a gift, income, a transfer of your own assets, etc.), it may become subject to gift tax or income tax. It is important to keep the purpose of the remittance clear.

02Remittances over ¥1 million and the overseas-remittance record

When there is a remittance to, or receipt from, abroad exceeding ¥1 million per transaction, the financial institution submits an "overseas-remittance record" to the tax office. This lets the tax office grasp who exchanged how much with abroad, and when.

03The obligation to file a foreign-asset report

A resident who holds a certain amount of assets abroad (a total exceeding ¥50 million) is obliged to file a "foreign-asset report". This includes overseas real estate, deposits, securities and the like.

Key point
Filing the foreign-asset report on time carries a benefit: even if there is later an omission regarding those assets, the additional tax is reduced. Conversely, not filing when obliged can lead to a heavier additional tax.

04Adjusting for double taxation on foreign income

A Japanese resident is, in principle, taxed in Japan on all income, domestic and foreign. However, if you have already paid tax abroad, the "foreign tax credit" may adjust for double taxation. Taxing rules may also be set by "tax treaties" between countries.

For those with income or assets abroad, an omission can later lead to a large back-tax bill. Consult a specialist early. We support you in five languages.

Summary

Overseas remittances over ¥1 million are grasped by the tax office via the overseas-remittance record.

Holding over ¥50 million of assets abroad triggers an obligation to file the foreign-asset report.

Foreign income can be adjusted for double taxation via the foreign tax credit or a tax treaty. If unsure, turn to a specialist.
