This study investigates the influence of strategic audit planning on audit performance through audit judgment and quality. Also, we examine two moderating effects: environment uncertainty and time pressure influence on the relationships. We developed the new components of strategic audit planning: internal control system evaluation, business risk assessment, fraud risk analysis, and technology intensity. Data were collected from 154 tax auditors. The results indicated that the greater degree of strategic audit planning is more likely to achieve higher audit judgment and quality but no influence of a moderator - environment uncertainty. Interesting, the results also demonstrate that auditor with higher degree of audit judgment and quality potentially promotes greater audit performance. Additionally, the moderate effect of time pressure on the relationships is partially significant. Contributions, suggestions and conclusions are provided for future research
