Calculating U.S. Tax Liability on Foreign Investment Income

U.S. taxpayers are required to report and pay taxes on foreign investment income, which includes dividends, interest, and capital gains earned from sources outside the United States. This income is subject to U.S. taxes, regardless of whether the funds are repatriated to the United States, as they are deemed repatriated.

Let’s clarify how U.S. tax liability is calculated for the different types of foreign investment income:

U.S. taxpayers are required to pay taxes on dividend income received from foreign investments. This dividend income is taxed differently depending on whether it is categorized as qualified or non-qualified. Let’s explore these categories in detail.

Qualified Dividends

A foreign dividend is considered qualified if it satisfies specific threshold requirements.

Generally, the foreign qualified dividend should meet any of the following requirements:

Holding Period: The U.S. shareholder should hold the stock for over 60 days within a 121-day period that started 60 days before the ex-dividend date. This timeframe is essential for qualifying for lower capital gains tax rates.

Qualified Foreign Corporation: The dividend should come from a qualified foreign corporation that meets one of the following conditions:

  • Incorporated in a U.S. possession.
  • Eligible for benefits under the U.S. income tax treaty with foreign countries.
  • The corporation’s stock is traded on an established U.S. securities market.

U.S. tax treatment of Qualified Dividends:

Qualified dividends are taxed at a preferential rate, typically 20%, depending on the taxpayer’s income. In contrast, ordinary dividends can be taxed at rates as high as 37%.

Nonqualified Dividends

Nonqualified dividends are those dividends that do not conform to the criteria for qualified dividends.  

Nonqualified dividends usually do not receive the same preferential treatment as qualified dividends.  This means they are taxed at the U.S. taxpayer’s individual marginal income tax rate. 

Please note that the U.S. taxpayers may be subject to withholding tax on the abovementioned dividend income in foreign countries. To avoid double taxation on dividends, U.S. taxpayers can utilize the lower rates provided under applicable tax treaties.

When a U.S. citizen invests in foreign assets, they may realize capital gains from those investments. Once these gains are realized, they are generally subject to U.S. federal income tax, regardless of the location of the investment. The taxation of these foreign investment gains typically depends on whether they qualify as short-term or long-term.

Short-term capital gains are gains that arise from assets held for one year or less. Such gains are taxed as ordinary income rather than as capital gains. In contrast, long-term capital gains are gained from assets held for more than one year. Such gains may qualify for lower capital gains tax rates, as they are treated as passive income.

Let’s explore these classifications in detail:

Short-term Capital Gains

Short-term capital gains are the gains earned from selling an asset or assets that have been held for one year or less. These gains are taxed at the taxpayer’s highest marginal tax rate, which falls within the regular income tax brackets. It ranges from 10% to 37% for 2025.

Long-term Capital Gains

Long-term capital gains refer to profits earned from selling an asset that has been owned for more than one year. The long-term capital gains tax rates are divided into three brackets: 0%, 15%, and 20%, based on the investor’s total taxable income.

Please note that the U.S. taxpayers may be subject to withholding tax on the abovementioned capital gains in foreign countries. To avoid double taxation on capital gains, U.S. taxpayers can utilize the lower rates provided under applicable tax treaties.

A Passive Foreign Investment Corporation (PFIC) is a type of foreign corporation that generates passive income or holds assets producing such income.

The PFIC rules pertain to information disclosure and detailed income reporting requirements for certain foreign investment structures owned by U.S. persons. These foreign investment structures exist as passive foreign investment companies (PFICs).

Let’s understand the rules in detail, which are as follows:

PFIC Qualification

A Passive Foreign Investment Company (PFIC) is a foreign corporation that meets at least one of two annual tests.:

  • Income test: At least 75% of the company’s gross income should be passive, including dividends, interest, royalties, rents, or capital gains.
  • Asset test: At least 50% of the company’s assets should generate passive income.

The two tests are applied each tax year, meaning an investment may be considered a PFIC one year but not the next.

Classic Examples of PFICs:

The most common forms of PFICs are as follows:

  • Foreign mutual funds
  • Foreign hedge funds
  • Similar foreign pooled-investment arrangements
U.S. Tax Impact of PFICs:

PFICs (Passive Foreign Investment Companies) can have significant tax implications for U.S. taxpayers. In the first year, any income generated by a PFIC is taxed as ordinary income at the highest marginal rate.

In subsequent years, if there is an increase in distributions from the PFIC, additional U.S. tax implications arise. If the increase in distributions that exceeds 125% of the average income from the previous three years (or the holding period if it is less than three years), this increase is considered an “excess distribution.” This excess portion is subject to a special “deferred tax” that the taxpayer must add to their tax that otherwise is due.

Please note that U.S. taxpayers may be subject to taxes on the PFIC distributions in foreign countries. To avoid double taxation on such income, U.S. taxpayers can utilize the lower rates provided under applicable tax treaties.

Foreign rental income refers to the income generated from rental properties owned by U.S. persons that are located outside the United States.

Foreign rental property owned by a U.S. tax resident is subject to U.S. taxation.

This means that the U.S. taxpayer typically reports their foreign property rental income and expenses in the same way as they would for a U.S. rental property.

Income generated from a foreign rental property is typically taxed as ordinary income in the United States. This means it will be subject to the regular income tax rate in the year it is received. However, the U.S. taxpayer may be eligible for foreign tax credits.

Example: You own a rental property in India as a U.S. Citizen. You receive certain rental income from the Indian property. That income is subject to U.S. income tax at ordinary income rates. However, any income taxes you paid to the Indian government on that rental income may be eligible for foreign tax credit treatment on your U.S. tax return. This will potentially reduce your U.S. tax liability on that same income. The rental income and expenses are required to be reported on Schedule E (Form 1040).

When a U.S. person owns rental property abroad, they may be able to claim depreciation. Depreciation is a way used to distribute the cost of a property over its useful life, reflecting its decreasing value. This allows for deducting a portion of the property’s cost each year to account for depreciation.

The depreciation of foreign properties functions differently from that of domestic properties. Residential rental properties are depreciated over a span of 27.5 years, while foreign residential properties are depreciated over a span of 30 years. (IRC Section 168(g)(1)(A)).

Please note that U.S. taxpayers may be subject to taxes on the rental income received in foreign countries. To avoid double taxation on such rental income, U.S. taxpayers can utilize the lower rates provided under applicable tax treaties.
