This study identifies the factors that influence voluntary auditor turnover. This research population is all manufacturing companies listed on the Indonesia Stock Exchange in 2017-2019. There are 294 samples selected using a purposive sampling method. Hypothesis testing uses a logistic regression analysis.

However, three other factors, namely audit opinion, going concern opinion, and audit reporting lag, do not affect auditor turnover.
