The template includes conditional logic to show relevant fields based on calculation methods chosen, ensures accurate data capture for both 60% safe harbour and 110% worldwide group debt tests, and provides a clear structure for documenting all required IRD information. Whether you're working in-house for a corporate group or serving multiple clients as an accounting firm, this template adapts to your workflow.
