現今政府施政講求「簡政便民」之改革理念,我國現行綜合所得稅的課徵在稅制和稅政上雖也具有穩定的基礎和效率,惟觀其在實務上所顯現的租稅負擔公平、減免扣除項目的適當性,稽徵作業手續繁雜以及經濟社會發展趨勢等問題,再者,依司法院釋字第696號解釋,宣告有關夫妻非薪資所得強制合併計算,較之單獨計算稅額,增加其稅負部分,形成對有無婚姻關係而為稅捐負擔的差別待遇,違憲。前述問題,皆與綜合所得稅的課徵制度有所牽動。綜此,本研究從綜合所得稅制度之現況情形,及租稅公平及稽徵效率等角度加以整理分析,發現現行家戶所得合併申報制度所產生的稅制繁複等諸多問題,建議應以單獨申報制度,更為理想,畢竟一套公平合理的租稅制度,還是要有健全而有效率之稅務行政,才能使公平稅制徹底執行。
