The geographic proximity has faced challenges with the existence of COVID-19 pandemic since 2019. This study aimed to scrutinize the effect of geographic proximity and audit quality by using COVID-19 pandemic as a moderating variable to compare before and after the situation. The samples of this study were Indonesian listed companies from 2018 to 2020 in Indonesia Stock Exchange. This study overcame self-potential selection bias and analyzed using Coarsened Exact Matching and Heckman's 2-Stage Least Square (Heckman 2-SLS). This study found that geographic proximity is significantly associated with the post-pandemic period, whereas geographic proximity did not cause problems before the pandemic. We also provided sufficient evidence of (Coarsened Exact Matching) CEM and Heckman 2-Stage Least Square which found that there were significant and appropriate results of our initial testing. The study implications relate to the auditor to consider pandemic as a factor that has effect on the audit fee.
