Key Audit Matters (KAMs) play a significant role in financial reporting and have
garnered significant attention in recent years. This systematic review of 78 studies published between June 2013 and December 2022 contributes to the audit and financial reporting field by identifying research gaps and suggesting areas for future research.
The findings show that KAMs significantly impact financial reporting and emphasise the need for further investigation into their effectiveness in improving financial reporting quality. This study provides valuable insights for regulators, stakeholders, and the academic and professional community and highlights the importance of future research on KAMs to assess the success of regulatory changes in audit reporting.
