Independence is crucial for auditors in various engagements, not just in traditional audits. Engagements that require auditor independence include reviews of financial statements, compilations, and agreed-upon procedures. In these cases, independence ensures that auditors can provide unbiased and objective opinions or reports, increasing stakeholders' confidence in the information presented.

Independence is also important in non-audit engagements like consulting, tax preparation, or advisory services. Even though independence might not be a strict requirement, it helps maintain credibility and trust. When auditors remain impartial, they avoid conflicts of interest, protect their professional reputation, and uphold ethical standards. This ultimately benefits clients, who receive more reliable advice and services.

An auditor independence is vital in various engagements, whether required or not, as it promotes trust, objectivity, and ethical conduct, leading to better outcomes for all parties involved.
