This Chapter establishes definitions pertinent to taxation, particularly focusing on terms such as "domestic tax," "foreign tax," and "permanent establishment." It clarifies the criteria for "associated entities" and delineates the conditions under which payments may be deemed as "excluded payments" in the context of taxation. Additionally, it references relevant agreements, such as the EEA Agreement, and outlines the implications of tax residence.

Key provisions address the taxation characteristics of different territories, including "zero-tax territories" and "listed territories," guiding compliance frameworks for organisations operating across jurisdictions. This ensures clarity in tax obligations and enhances regulatory alignment.
