🇺🇸 United States — 🇬🇧 United Kingdom

Tax Treaty / Double Tax Avoidance Agreement detail

The US-UK Income Tax Convention, signed 24 July 2001 and in force since 31 March 2003, is one of the most comprehensive bilateral tax treaties in existence. It replaced the 1975 treaty and its subsequent protocols, substantially modernising the framework governing cross-border income flows between the two countries. On dividends, the treaty reduces withholding to zero for qualifying pension funds and companies holding at least 80% of voting stock for a 12-month period; to 5% for companies owning at least 10% of voting shares; and to 15% for all other dividends. Interest payments between the two countries face zero withholding under the treaty, as do royalties, making it unusually generous compared with the OECD model. The treaty contains a detailed Limitation on Benefits (LOB) article designed to prevent third-country residents from using either the US or UK as a conduit. Only 'qualified persons'—residents satisfying ownership and base-erosion tests, publicly traded companies, pension funds, charities, or those engaged in active trade or business—can access reduced rates. A saving clause allows each country to tax its own citizens and residents as if the treaty did not exist, limiting treaty benefits for outbound investors who retain domestic tax liability. The two countries also maintain a Totalization Agreement on social security, preventing dual contributions. The treaty does not override domestic controlled-foreign-corporation (CFC) rules, alternative minimum tax, or branch profits tax in most cases. Residency tie-breaking follows the standard OECD cascade: permanent home, then centre of vital interests, habitual abode, and nationality, with competent authority mutual agreement as a final resort. Protocol amendments in 2002 refined several provisions before entry into force.
