The UK tax system operates within a global framework, interacting with tax systems of other jurisdictions through international tax treaties, trade agreements, and regulatory initiatives. These interactions influence how individuals and businesses manage cross-border taxation, ensuring compliance while minimizing double taxation. The UK adheres to international tax principles set by the Organisation for Economic Co-operation and Development (OECD) and the European Union (EU), despite Brexit. Understanding how the UK tax system interacts with other jurisdictions is essential for multinational corporations, expatriates, and global investors.
