One of the qualitative characteristics of financial reporting is relevant. Its manifestation can be seen from the timeliness of reporting. Timeliness could be judged from the audit report lag, which is the length of time from the end of company’s fiscal year to the date of auditor’s report. This research aims to empirically examine the influence of firm size, operation complexity, auditor quality, and auditor’s opinion on audit report lag of manufacturing companies listed in Indonesia Stock Exchange.

Subsequently in partial, variables ‘firm size’, ‘auditor’s opinion’ have a significant and positive effect on audit report lag, the ‘auditor quality’ has a significant and negative effect on audit report lag, while the variable ‘operation complexity’ has no significant effect on audit report lag.
