Tax Aggressiveness over the Corporate Life Cycle
Tax Aggressiveness over the Corporate Life Cycle
摘要
本研究主要探討公司避稅行為與生命週期的關係，資料來源為台灣經濟新報社TEJ資料庫，研究範圍為1999-2012年，以台灣公開發行公司(包含上市及上櫃公司)為樣本，本文想了解當企業在不同的生命週期階段，面臨不同的經濟環境是否採取不同程度的避稅行為。本文建立的迴歸模型來驗證假說，實證結果顯示當企業在不同的生命週期階段會採取不同程度的避稅行為。獲利能力，公司規模和上年累計稅收差異是三個顯著影響生命週期中各個階段公司避稅行為的因素。研究結果還顯示，營利事業所得稅稅率的降低的確會減少企業的避稅行為。 本研究最主要的貢獻就是補充和擴展了近期公司避稅行為與企業生命週期文獻。本文解釋那個生命週期階段的企業較會從事積極的避稅行為。這是第一次有研究去討論企業積極的避稅行為和生命週期關係和探討各個生命週期，有那些特質的企業會積極從事避稅行為，研究結果可以提供投資者一個評估公司的方法，因為積極的避稅行為可能會提高風險，增加成本。營利事業所得稅稅率的降低對企業的避稅行為影響，說明了政府調降營所稅的確可以幫忙打消企業從事避稅的念頭，也代表此政策實施之有效性。

The increase in tax gap shows that tax aggressiveness is on the rise and among the most significant enforcement problems. This paper aims to explore whether corporations, when facing the distinct financial environment in different life cycle stages, will adopt a different level of tax aggressiveness. This paper builds the regression model to verify the hypothesis. The empirical results indicate that corporations in different life cycle stages will adopt a different level of tax aggressiveness. Profitability, company size and book-tax difference of previous year are the three factors to affect corporate tax aggressiveness behavior significantly in every life cycle stage. The results show that the reduction of the profit-seeking enterprise income tax rate will change the level of corporate tax aggressiveness. The study complements and extends the recent literature that links tax aggressiveness with the corporate life cycle. This paper provides some explanations for why some firms do not engage in tax aggressiveness. This is the first study to discuss the relation between tax aggressiveness and the corporate life cycle, which adds the exploration to the recent stream of research on the determinants of corporate tax aggressiveness. Practically, various stakeholders, such as investors, managers, lenders, and creditors, can employ the research to analyze and assess tax aggressiveness of corporations.
