Worldwide Income Taxation for US Residents and Japanese Financial Assets
US citizens and green card holders are considered “US residents” for tax purposes and are subject to US taxation on their worldwide income, regardless of where they reside. This includes Japanese pensions and life insurance surrender proceeds. However, by properly applying the US-Japan Tax Treaty, it may be possible to avoid double taxation or exempt certain types of income from US tax. This article explains how Japanese pension and life insurance surrender proceeds are treated in the US, including reporting on Form 1040 and the application of the US-Japan Tax Treaty.
US Taxation of Japanese Life Insurance Surrender Proceeds
General Principle of Taxation
When you surrender a Japanese life insurance policy and receive surrender proceeds, the portion that exceeds the total premiums paid (the gain) is generally subject to US taxation. This gain is typically treated as ordinary income and reported on Form 1040, such as on Schedule 1 (Additional Income and Adjustments to Income), Part I, line 8z (Other income).
Application of the US-Japan Tax Treaty (Article 21: Other Income)
Article 21 (Other Income) of the US-Japan Tax Treaty states that “Items of income of a resident of a Contracting State, wherever arising, not dealt with in the foregoing Articles of this Convention shall be taxable only in that Contracting State.” For a US resident who realizes a gain from the surrender of a Japanese life insurance policy, this gain is generally taxable only in the United States. Therefore, if any tax was withheld in Japan, a refund procedure in Japan may be necessary. If the tax withheld in Japan is not refundable, it may be possible to claim a foreign tax credit (Form 1116) in the US, but seeking a refund from Japan is generally the first step.
US Taxation of Japanese Pension Income
General Principle of Taxation
US residents receiving Japanese pensions (e.g., Kosei Nenkin, Kokumin Nenkin, corporate pensions) are generally required to report this pension income in the US. Pension income is reported on Form 1040, Schedule 1, line 5b (Pensions and Annuities).
Application of the US-Japan Tax Treaty (Article 17: Pensions, Annuities, Alimony, and Child Support)
Article 17 of the US-Japan Tax Treaty is crucial for Japanese pension income. This article clearly defines taxing rights based on the type of pension:
- Private Pensions (e.g., corporate pensions) – Article 17, Paragraph 1: “Pensions and other similar remuneration derived and beneficially owned by a resident of a Contracting State in consideration of past employment shall be taxable only in that Contracting State.”
This means that if a US resident receives a private Japanese pension, such as a corporate pension, it is taxable only in the United States, and Japan cannot tax it.
- Public Pensions (e.g., Kosei Nenkin, Kokumin Nenkin) – Article 17, Paragraph 2: “Social security benefits and other public pensions paid by a Contracting State to a resident of the other Contracting State or to a citizen of the United States shall be taxable only in the first-mentioned Contracting State.”
This means that public pensions paid by the Japanese government (or its agencies), such as Kosei Nenkin and Kokumin Nenkin, are taxable only in Japan, even for US residents. They are exempt from US taxation. In such cases, Form 8833 (Treaty-Based Return Position Disclosure) must be filed in the US to claim the treaty benefit and exclude the income from US taxable income.
Potential for Foreign Tax Credit (Form 1116)
If, despite the application of the US-Japan Tax Treaty, the same income is taxed by both Japan and the US (e.g., if Japanese life insurance surrender proceeds are subject to withholding tax in Japan and not refunded), it may be possible to claim a foreign tax credit (Form 1116, Foreign Tax Credit) in the US to mitigate double taxation. However, since the tax treaty takes precedence, it is crucial to first confirm the taxing rights based on the treaty.
Information Reporting Obligations: FBAR (FinCEN Form 114) and FATCA (Form 8938)
Accounts receiving Japanese life insurance surrender proceeds or pension payments, or the pension assets themselves, may be subject to US information reporting requirements. If you hold foreign financial accounts exceeding certain thresholds, you may need to file FBAR (FinCEN Form 114, Report of Foreign Bank and Financial Accounts) and FATCA (Form 8938, Statement of Specified Foreign Financial Assets). These reporting obligations are separate from income taxation, so it is important to be aware of them.
Consult a Professional
US-Japan tax matters are complex, and the applicable treaty provisions and tax laws vary depending on individual circumstances. Specifically, the tax implications can change based on the type of pension, the terms of the insurance contract, and the timing of receipt.
