Audit delay refers to the time from the end of the country or company’s financial year to the date of the audit report. The chances of delay of audit in the public sector are pervasive and as such the expectations of users of these audit reports may differ which could result in the quality and reliability of these audits within this sector to be questioned. Accordingly, the purpose of this study is to explore the external and internal factors that cause audit delay and the aftermath they have on public sector audit quality. As for this study, its original value correlates with the espousal of the institutional theory from the perspective of public sector auditing. Considering the aim of this study, a qualitative research was preferred with the objective of gathering in-depth and enriched empirical data; hence, semi structured interviews were conducted with ten auditors of the top and middle management of the Supreme Audit Institution (SAI) of Liberia – General Auditing Commission. There are varying views regarding the findings of this study as the respondents disclose that the external factors that result to audit delays are caused by either the audited entity or other external parties and not the SAI; however, it is the responsibility of the SAI to work with the entity involved to ensure those factors do not impede the audit process to the extent it cannot be completed; whereas, internal factors which includes inadequate staff training, delay in the review and approval of the draft audit report by top management to the poor performance of auditors as a result of lack of knowledge and etcetera cause audit delays as well and the SAI is solely responsible for ensuring that they are resolved or lessened so as not to affect the timeliness of the reporting process. The study mentions several limitations. One of them is the lack of observation being conducted which would have provided first-hand information on factors that cause the delay of audits in the public sector.
