摘要

本論文使用台灣上市公司1998到2007年的資料,本論文延伸之前有關財務報表資訊的避稅參予研究。和先前研究不同的地方在於本論文使用了三種不同的衡量方法:(i)評估長期現金的有效稅率(LRETR), (ii)財稅差異(BTD), (iii)剩餘財稅差異(DD_BTD)。此外台灣在2006年施行的最低稅負制(AMT)亦列入考量。因此我也探討台灣公司在最低稅負制施行前後的稅務管理活動差異。
研究結果指出財稅差異和長期性的稅務管理呈現負相關。在財稅差異稅務管理的一種衡量呈現出稅務管理活動和財務槓桿的負相關。我的結論中亦顯示出在最低稅負制之實行前和實行後公司在稅務管理上的差異。這顯示出最低稅負制的執行促使公司對於稅務規畫更為積極。
在其他分析中使用非常低的長期現金的有效稅率,本研究一種衡量方式來評估減免稅的合法手段,以發現出財稅差異、DAP和SIZE的強烈正相關。研究發展變數在羅吉斯回歸中亦呈現出正相關。本研究指出了長期現金的有效稅率和NOL在OLS回歸下的負相關;然而避稅活動變數和NOL在羅吉斯回歸中為高度正相關。我也發現避稅活動變數和LagETR 與EqEarn為負相關。這些結果指示出美國基金預測的負相關,那可能起因於不同的租稅措施和所得稅政策下所導致。

Using data of Taiwanese public firms for period between 1998 and 2007, this study extended prior empirical work on inferring tax shelter participation from financial statement information. Unlike in these prior studies (i.e., confidential information of tax shelter cases of firms), I employed three distinct commonly used measures: (i) the estimated long-run cash effective tax rate (LRETR), (ii) the total book-tax difference (BTD), and (iii) the residual book-tax difference (DD_BTD). In addition, the Taiwan government takes Alternative Minimum Tax (AMT) into consideration, starting 2006. Thus, I also examined that difference between the firms’ tax management activities before and after the implementation of AMT.
Results indicated that BTD and SIZE are negatively correlated with long-run tax management. For BTD measurements of the tax management proxy, there is negative correlation between tax management activity and leverage. My results also show a positive significant difference between firms before and after the implementation of AMT. This suggests that firms with the implementation of AMT are significantly more tax aggressive than those firms without.
In additional analyses, using a very low LRETR, this study developed a measurement which estimated the probability that a firm engages in a tax shelter and found out that the coefficients of BTD, DAP, and SIZE remained with strong positivity and the R&D variable are both positive and significant in the logistic regression. The results of this study show that LRETR is negatively correlated with NOL in the OLS regression, while tax shelter activity has a strong significant positive correlation with NOL in the logistic regression. I also found that tax shelter activity is negatively correlated with LagETR and EqEarn. These results suggest that the opposite correlations work against prediction of the Treasury (1999) of U.S and these results could be caused by the different tax policy and corporate income tax regimes from U.S.
