Taiwan Shares, US Investors and Two Tax Systems

A US investor who buys TSMC on the Taiwan exchange, or the Taiwan-listed 0050 ETF, through an account with direct access to those securities faces Taiwan tax on a sale or a dividend. US tax and reporting may still apply to the same holding.

For a US person who is not a Taiwan income-tax resident, Taiwan-listed securities held directly can have a different legal and tax structure from a US-listed receipt or a US-domiciled fund. Taiwan residency, the type of security and the legal owner named on the account can all affect the tax treatment. If time in Taiwan leaves residency uncertain, the separate Taiwan income-tax residency guide addresses that question.

Opening a Taiwan brokerage account

Article 10 of the Regulations Governing Investment in Securities by Overseas Chinese and Foreign Nationals requires foreign nationals to register with the Taiwan Stock Exchange under its rules before investing in Taiwan securities, with limited exceptions under that article. The TWSE’s foreign-investment guidance explains that a foreign investor obtains an investor ID before opening a local brokerage trading account.

For a foreign individual in Taiwan, the TWSE describes how a securities broker submits the registration and then opens the account. For someone outside Taiwan, its offshore guidance says the investor uses a domestic agent or representative and registers before the brokerage account is opened.

The broker can clarify which route fits your residence and documents, who will be named as the registered investor, and how cash and custody will be handled. Access through a foreign app does not necessarily provide a Taiwan brokerage account or the same record of beneficial ownership. Retaining the registration, account agreement and transaction statements helps identify who receives dividends and who may claim shares in an estate.

Taiwan taxes the sale price

Taiwan’s Securities Transaction Tax Act imposes tax on the seller’s transaction price, separate from income tax on any gain. The Ministry of Finance’s rate guidance and stock FAQ state that the ordinary tax rate on stock sales is 0.3% of the sale price.

For qualifying investment-trust beneficiary certificates, the MOF’s beneficiary-certificate FAQ gives a rate of 0.1%. For a Taiwan-listed ETF such as 0050, that rate applies only if it falls within the qualifying beneficiary-certificate category and no special transaction rule changes the treatment. The tax is borne by the seller; the MOF explains how it is collected.

Separately, Income Tax Act Article 4-1 suspends income tax on securities transaction gains and bars the deduction of losses on those transactions from taxable income. This is a Taiwan income-tax rule. A US person may still owe US capital-gains tax. Keep purchase and sale confirmations, fee details and currency-conversion records for the US tax calculation. A sale involving a special instrument or a nonstandard structure requires its own classification; the treatment of an ordinary stock sale may not apply.

Dividend withholding and the treaty question

For a nonresident individual, Article 3(1) of the Withholding Rates Standards sets Taiwan withholding on company dividends at 21% of the amount paid. That is the domestic rate on an ordinary dividend from a Taiwan company to a nonresident individual.

An ETF distribution may contain different components or differ from a company dividend in who pays it and how it is reported. The distribution and withholding statement helps distinguish those components: a cash payment is not necessarily a company dividend. If the investor is a Taiwan tax resident, the nonresident rule is the wrong starting point.

The IRS list of US income tax treaties in force does not include Taiwan. Taiwan’s Ministry of Finance treaty list likewise shows no comprehensive income tax agreement with the United States; the US appears only under a 1988 shipping and air-transport agreement. As of September 30, 2026, no US–Taiwan income tax treaty is in force that reduces this Taiwan dividend withholding for a US resident.

H.R. 33, the United States–Taiwan Expedited Double-Tax Relief Act, passed the House on January 15, 2025 and was referred to the Senate Finance Committee. As of September 30, 2026, it has not become law (Congress.gov bill status). The House-engrossed text remains a bill, not an enacted treaty or tax rate. A hoped-for future rate is no basis for planning a dividend; the rate on those ordinary company dividends is still 21%.

US tax and reporting

The IRS’s Form 1116 instructions explain that an eligible foreign income tax paid or accrued on foreign-source income may support a foreign tax credit, subject to limitations, categories, holding-period rules and documentation. The IRS foreign-tax-credit page explains the general process; it does not say every amount withheld in Taiwan becomes a dollar-for-dollar US credit.

The Taiwan withholding certificate and payment details document the tax paid. A US adviser can determine whether the tax is creditable, the income’s source and category, and whether Form 1116 or an exception applies. Taiwan’s transaction tax is not automatically an income tax eligible for that credit.

Before buying a Taiwan fund, an investor needs advice on the passive foreign investment company (PFIC) rules. Under IRC section 1297, as summarized in the IRS Form 8621 instructions, a foreign corporation meets the PFIC definition if at least 75% of gross income is passive or at least 50% of its average assets produce, or are held to produce, passive income. The IRS Form 8621 page describes reporting by certain US shareholders.

For 0050, PFIC status depends on the fund’s legal and US tax classification and on the year at issue. A review with a US tax adviser can cover the specific holding, possible Form 8621 filing and any elections before a purchase or distribution creates a difficult reporting history. Direct TSMC shares and a Taiwan fund can be taxed differently in the US.

Shares kept in a Taiwan financial account can bring a further US reporting obligation. According to the IRS, certain foreign brokerage or bank accounts can trigger an FBAR on FinCEN Form 114 when the aggregate value of foreign accounts exceeds the applicable reporting threshold. Form 8938 separately concerns specified foreign financial assets above applicable thresholds.

The IRS comparison explains that these are distinct reporting regimes. Which rules apply depends on the account structure, the assets, and the investor’s filing status and residence. Both sets of rules can be reviewed with a US adviser.

Taiwan shares after the owner dies

Article 9(8) of Taiwan’s Estate and Gift Tax Act treats shares as located where the issuing company or the business in which the investment is held has its head office. Shares of a company headquartered in Taiwan can therefore be Taiwan-situs estate property even if the investor and heirs lived elsewhere.

The nationality and residence rules, and the filing and transfer documents, are covered in Taiwan estate tax after a death abroad. For a Taiwan-listed ETF, applying that location rule requires a review of its legal form and issuer.
