Let's look at the difference in roles between internal and external audit
Audio Player
Objective & Planning
Internal Audit
Dictated by management - planning follows this
However, good corporate governance would allow IA a degree of independence over objectives
External Audit
Ensure accounts free from material misstatement and prepared in line with reporting framework.
Planned in accordance with ISAs
Work planned by themselves
Evidence
Internal Audit
The amount / type gathered would depend upon the objective set
Eg It may just be a check that assets exist, with no concern over their value
External Audit
Governed by IAS 330 - gather evidence to address misstatement risk
The risk would have been analysed during planning and in the light of subsequent evidence
Reporting
Internal Audit
Determined by the nature of the assignment
External Audit
Determined by statute & ISAs 700/5/6
Communicate to stakeholders
