The control variable in this study – audit’s experience was included to account for tax auditors attitudes that may influence the hypothesized relationships. Audit’s experience was measured by the number of years that tax auditor has been in the audit field. Normally, audit’s experience may influence on strategic audit planning to implement judgment and quality of audits in order to achieve superior performance. Consistent with Choo (1996) indicated that the auditors’ knowledge affect their judgment performance. Especially, inexperienced auditor‘s judgments differed from experience auditors’ judgments when in uncertainty context (Hoffman et al., 2003). In addition, the specialized (expertise) auditors who trained and with practical experience in a particular industry (Grmling and Stone, 2001) provide high – quality audit (Lowensohn et al., 2007) and detect errors in financial statement effectively (Hammersley, 2006).
