Income determination: Since no income taxes are imposed on individuals in the Cayman Islands, income determination is not relevant in the context of Cayman Islands taxation.

Deductions: Since no income taxes are imposed on individuals in the Cayman Islands, deductions from income are not relevant in the context of Cayman Islands taxation.

Note: Cayman paying agents making interest payments to individuals who are tax resident in an EU member state may have to report interest paid under the terms of the Reporting of Savings Income Information Law.

This reporting is typically done using the "Annual Reporting Form".

The specific form used for this compliance is known as "Form ARF" (Annual Reporting Form for Savings Income Information). The form captures details of the interest payments made and provides necessary information to the Cayman Islands Tax Information Authority for onward transmission to the relevant EU tax authorities.

It’s crucial for paying agents to ensure accurate and timely reporting to comply with the law and avoid potential penalties.
