Many foreign residents in Japan are unaware that they may be required to report overseas assets even when no Japanese tax is due.
Hello, my name is Taisei Koshida, and I am a certified public accountant and tax accountant.
I aim to assist non-Japanese business owners who need help with reading or writing in Japanese. If you find the Japanese tax system challenging, I can help you with your tax filings.
If the total value of your overseas assets exceeds 50 million yen as of December 31, you may be required to file a Statement of Overseas Assets with the Japanese tax office.
In this article, I will explain who needs to file, what assets are reportable, and the penalties for failing to comply.
1. Who Must File a Statement of Overseas Assets?
Individuals who are tax residents of Japan and whose overseas assets exceed 50 million yen as of December 31 may be required to file.
2. What Assets Must Be Reported?
Bank deposits are classified according to the location of the financial institution.
Real estate is classified according to where the property is located.
Securities are generally classified according to the location of the issuing company or institution.
3. How Are Overseas Assets Valued?
Assets are generally valued at their fair market value as of December 31. If the market value is not readily available, a reasonable estimate may be used.
4. When Is the Filing Deadline?
The filing deadline is June 30 of the following year.
5. Penalties and Benefits of Filing
If you file the Statement of Overseas Assets on time and cooperate during a tax audit, certain penalties may be reduced by 5%.
On the other hand, if you fail to file the statement properly, the penalty may increase by 5%. Furthermore, if you refuse to provide supporting documents, the penalty may increase by up to 10%.
Knowingly submitting false information may result in imprisonment of up to one year or a fine of up to 500,000 yen.
Many foreign residents also ask how IRAs, Roth IRAs, and 401(k) retirement accounts should be reported in Japan.
6. Foreign Securities, IRAs, and 401(k)s: Cost Basis and Japanese Tax Rules
Regarding securities, cost basis information is required. This means that, in principle, you need to calculate the average acquisition cost in yen using the moving-average method whenever you purchase additional securities. This is the official method used in Japan.
In addition, each stock or fund should generally be reported separately. If you report them on an aggregated basis and later realize capital gains, there is a risk that your capital gains may be understated. If this results in an underpayment of tax, additional penalties may apply.
As for IRA and 401(k) retirement accounts, the most conservative approach would be to track each stock and fund separately in yen and report them individually. This would allow you to accurately calculate gains and losses when the investments are sold.
In Japan, distributions from IRAs, including Roth IRAs, are generally taxable. However, you can deduct the cost basis when calculating taxable income. The same principle applies to distributions from 401(k) accounts, and employer matching contributions may also be included in the cost basis.
Therefore, maintaining accurate cost basis information is very important from a Japanese tax perspective.
In my experience, many foreign residents are unaware of this reporting requirement because no tax is due merely by filing the statement.
However, penalties may apply if the form is not filed correctly. If you are unsure whether your overseas assets are reportable, consulting a tax professional may save you considerable time and trouble.
