What is a US tax treaty?
US tax treaties are agreements between the United States and other countries designed to prevent double taxation of income. For businesses, their most important function is to reduce the default 30% US withholding tax on payments like dividends, interest, and royalties made from a US company to a foreign owner in a treaty country.
Direct Question Answer
What is this guide about US tax treaties? An explanation of what US tax treaties are and how they work. Who should use US tax treaties? Non-resident founders and foreign companies with US investments or income. When should you use a US tax treaty? When structuring a US investment or when receiving payments from a US company.
Decision Summary
Who should claim US tax treaty benefits? Any non-resident receiving US-source income should work with a tax professional to determine if a treaty can reduce their US tax burden. Who can ignore US tax treaties? US domestic businesses with no foreign owners or foreign income can generally ignore tax treaties
For any non-resident doing business with or in the United States, the concept of "double taxation"—where the same income is taxed by both the US and your home country—is a major concern. To prevent this and facilitate international trade and investment, the US maintains a network of income tax treaties with more than 60 countries.
These treaties are legally binding agreements that override standard US tax rules. For foreign founders and businesses, they are one of the most powerful tools for optimizing their US tax position. This guide explains what tax treaties are, how they work, and their most important benefit: reducing withholding tax.
What is a Tax Treaty?
A tax treaty is an agreement between two countries to allocate taxing rights over income earned by their respective residents. For international founders and international companies, these treaties provide a certain amount of clarity on international tax liability—determining which country has the obligation/right to tax which income. The primary goals of these treaties are to:
- Avoid Double Taxation: By setting rules for which country gets the first right to tax specific types of income and requiring the other country to provide a credit for taxes paid.
- Reduce Tax Rates: By lowering the withholding tax rates that one country can impose on payments to residents of the other country.
- Prevent Tax Evasion: By establishing a framework for the exchange of tax information between the two countries' tax authorities.
You can find a list of all countries with which the US has a tax treaty on the IRS website.
The Key Benefit: Reducing Withholding Tax
As explained in our guide to US withholding tax, the default US rule is to impose a 30% tax on certain types of US-source income paid to foreign persons. This is where tax treaties have their biggest impact.
A tax treaty can significantly reduce or even eliminate this 30% tax. The specific rates vary from treaty to treaty, but here are some common examples for payments from a US company to a shareholder in a treaty country:
- Dividends: The 30% rate is often reduced to 15% or 5%.
- Interest: The 30% rate is often reduced to 0% or 10%.
- Royalties: The 30% rate is often reduced to 0%, 5%, or 10%.
For a foreign parent company receiving dividends and royalties from its US subsidiary, these reductions can result in millions of dollars in tax savings. Understanding available tax treaty benefits can therefore play an important role in managing the overall tax cost of cross-border transactions.
How to Claim Treaty Benefits: Form W-8BEN-E
You cannot simply decide to use a lower treaty rate. To legally claim the benefits of a tax treaty and allow the US payer to withhold tax at a reduced rate, the foreign recipient must provide the US payer with a valid, completed IRS Form.
- For Individuals: Form W-8BEN
- For Entities: Form W-8BEN-E
This form certifies that the recipient is a tax resident of a specific treaty country and is eligible to claim the benefits of the treaty. The US company paying the income must have a valid W-8 form on file before it can apply a reduced withholding rate.
The Catch: Limitation on Benefits (LOB)
Modern tax treaties contain complex "Limitation on Benefits" (LOB) clauses. These are anti-abuse rules designed to prevent residents of a third country from setting up a "shell company" in a treaty country just to take advantage of its tax treaty with the US.
To claim treaty benefits, a company must typically meet certain criteria demonstrating it has a genuine economic connection to the treaty country, such as being publicly traded there, or having active business operations and employees. Simply being incorporated in a country is often not enough.
Navigating the LOB provisions is one of the most complex areas of international tax and requires specialist advice. Foreign companies should carefully review these requirements as part of their cross-border tax compliance strategy.
Expertise is Essential
US tax treaties for Foreign Founders are powerful but complex instruments. Correctly applying them is not a DIY task. It requires a deep understanding of international tax law and the specific provisions of each treaty.
