Handling Dividends from China: The Structure of Double Taxation for Chinese Business Owners in Japan

2026-06-27

One question we hear again and again from Chinese business owners living in Japan is this: "I received a dividend from my company in China — do I have to report it in Japan too?" The profit came from a company back home, and tax was already withheld on the Chinese side. So why would Japan tax it again? In most cases, the answer is that you must report it. The real issue is not whether to disclose, but whether you correctly understand which scope of taxation you fall under.

Permanent Residents Are Taxed on Worldwide Income

The starting point is your residency category. Article 7, Paragraph 1, Item 1 of Japan's Income Tax Act subjects residents other than non-permanent residents — so-called permanent residents — to taxation on all income. Once your cumulative residence in Japan exceeds five years within any ten-year window, you leave the non-permanent resident category (Income Tax Act, Art. 2(1)(iv)). Most people who have lived and run businesses in Japan for years are already within the scope of worldwide taxation, and a dividend from a Chinese company is, in principle, taxable in Japan.

A Dividend Passes Through Two Countries in Turn

Cross-border dividends move through two tax systems in sequence.

Stage	What happens	Relevant mechanism
Source country (China)	Withholding at payment; the tax treaty caps the applicable rate	Japan–China tax treaty
Country of residence (Japan)	Reported as worldwide income, taxed at progressive rates	Income Tax Act, Art. 120 / Art. 89
Relief from double taxation	Foreign tax paid is credited up to a limit	Foreign tax credit (Income Tax Act, Art. 95)

In China, the source country, tax is withheld when the dividend is paid. The Japan–China tax treaty sets a ceiling on the rate the source country may impose, and with the proper procedures a reduced treaty rate may apply; the specific rates and conditions are governed by the treaty text and each country's procedural rules.

In Japan, the country of residence, you file that dividend as part of your worldwide income (Income Tax Act, Art. 120). Japanese income tax is progressive, and the portion of taxable income above ¥40 million is taxed at 45% (Income Tax Act, Art. 89), with resident tax applying on top.

The Foreign Tax Credit as an Adjustment Mechanism

If the same income is taxed by both China and Japan, the result is double taxation — and the foreign tax credit exists to adjust for it (Income Tax Act, Art. 95). The foreign income tax you paid in China can be credited against your Japanese income tax, up to the portion of that year's tax attributable to foreign-source income (the "creditable limit"). Any excess that cannot be fully credited may, in some cases, be carried forward for a limited period.

There is, however, a crucial precondition: the credit applies only once you have correctly reported your foreign income on your tax return and retained documents proving the tax was paid. Fail to file at all, and you not only lose the credit — you expose yourself to simultaneous scrutiny from two tax authorities.

Treat It as a Structural Question

Three things to confirm:

Are you a permanent or non-permanent resident? The scope of taxation changes fundamentally.
How much tax was imposed in the source country? This is the basis for the credit.
Can you show foreign income and proof of payment on your tax return? This is the precondition for the credit.

For cross-border income such as dividends, interest, and royalties, the work of getting organized begins by mapping three layers onto a single diagram: taxation in the source country, taxation in the country of residence, and the adjustment for double taxation.
