I. Case Overview

Company A is a tax resident of the United Kingdom that received income from the United States. Under the UK-US Tax Treaty, Company A sought an exemption from UK tax on this US-sourced income. However, the UK tax authorities denied the request, arguing that the income did not meet the conditions for tax exemption specified in the treaty. As a result, Company A applied for a unilateral tax credit under UK domestic law to avoid double taxation. The tax authorities also denied this application, stating that because the income did not qualify for exemption under the tax treaty, it should not be eligible for a unilateral tax credit under domestic law. Company A then brought the case to court.

II. Key Point of Dispute

The main issue in this case was whether Company A should receive a unilateral tax credit under UK domestic law for the US-sourced income when it does not qualify for exemption under the UK-US Tax Treaty.

Company A argued that denying a unilateral tax credit would result in double taxation of the same income, which contradicts the principle of avoiding double taxation as set out in international tax law and the goals of tax treaties. Company A further contended that UK domestic law should be interpreted in a way that aligns with international tax principles and the purpose of tax treaties, thus granting a unilateral tax credit to prevent double taxation.

The UK tax authorities maintained that the UK-US Tax Treaty already provides specific rules for avoiding double taxation. Since Company A’s income did not meet the criteria for exemption under the treaty, it should not receive any further relief under UK domestic law. The authorities emphasized that the tax treaty should take precedence over domestic law in this context.

III.Final Ruling

The court ruled in favor of Company A, allowing the unilateral tax credit under UK domestic law. The court concluded that the objective of both tax treaties and domestic tax relief laws is to avoid double taxation, and denying the unilateral tax credit would lead to unfair double taxation on Company A’s US-sourced income. The court also noted that the provisions of the tax treaty should not prevent the application of domestic law that offers additional relief when the conditions of the treaty are not met.
