Final answer:
The GAO has overreaching principles for determining whether a non-audit service impairs independence, including not performing management functions or making decisions, not auditing their own work or providing significant non-audit services for the subject matter, and not performing non-audit services that require independence.
Step-by-step explanation:
Under the independence standards of the GAO for performing audits in accordance with generally accepted government auditing standards, there are three overreaching principles for determining whether a non-audit service impairs independence:
- Auditors must not perform non-audit services that involve performing management functions or making management decisions.
- Auditors must not audit their own work or provide non-audit services in situations where the non-audit services are significant or material to the subject matter of the audit.
- Auditors must not perform non-audit services that require independence.
