對於企業而言，稅負為重要經營成本之一環，公司透過租稅規避得以減少稅負支出以提升企業競爭力，過去文獻指出避稅會提高公司企業風險但仍有意從事長期租稅規劃。由於企業是否從事避稅取決於經理人決策，因此經理人特質會影響公司決策方向。
本研究以2013至2018年台灣上市櫃公司資料為樣本，實證結果發現激勵薪酬與現金有效稅率呈負相關，表示當經理人有越高的激勵獎酬企業越會從事避稅行為，經理人過度自信對現金有效稅率呈正向關係但未達顯著影響，與預期結果不同。經理人年資與現金有效稅率呈負相關，表示經理人年資愈長對於避稅政策反而會趨於保守。經理人財務專業性與現金有效稅率呈顯著負相關，代表當經理人具有財會方面的專業能力愈可能採取避稅政策。總經理兼任董事長與現金有效稅率呈顯著負向關係，但本研究則未達顯著影響。
Tax is one of important operation cost for company, companies can increase competitiveness through reduce tax payment, suggest that tax avoidance increases the company's future risks, but the company is still willing to engage in long-term tax planning. Whether a company engages in tax avoidance depends on the manager’s de-cision, so the manager’s characteristics will affect the company’s decision-making di-rection.
This study was conducted in the period from 2013 to 2018, The empirical results found that incentive compensation and cash effective tax rate were negatively corre-lated, indicating that the higher the incentive reward, the more enterprises will engage in tax avoidance. CEO overconfidence and cash effective tax rate positive relation but no significant impact. CEO tenure and cash effective tax rate are negatively correlated, indicating that the longer the CEO tenure, the more conservative the tax avoidance policy will be. The financial professionalism of managers is significantly negatively correlated with the effective tax rate of cash, which means that the more likely a man-ager has the financial and accounting expertise to adopt a tax avoidance policy. The manager’s concurrent role as chairman has a significant negative relationship with the effective cash tax rate, but this study found no significant impact.
