RT Journal Article T1 The impact of auditor-provided non-audit services on audit quality: A review of the archival literature A1 Quick, Reiner A1 Sánchez-Toledano, Daniel David A1 Sánchez-Toledano, Joaquín Ignacio K1 Auditoría K1 Contabilidad K1 Informes de auditoría AB The paper gives an overview of the results of a structuredliterature review. It covers archival studies on the relationshipbetween non-audit services (NAS) fees and factual as well asperceived audit quality published in journals included inthe accounting subject category of the SCImago Journal Ranking. Italso includes a critical evaluation of the research methods appliedin prior research and offers avenues for future research.The provision of NAS to audit clients creates threats to auditorindependence. Consequently, regulators have focused onthe simultaneous provision of audit and NAS for many years andrestricted it over time. This paper aims to assess which regulatoryactions are justified in light of related archival research findings.Overall, prior research does not clearly prove a negative impact ofnon-audit services on factual audit quality. However, itdemonstrates a negative relationship between non-audit fees andaudit quality perceptions. Moreover, it also reveals that taxconsulting fees are less problematic.
