本研究使用財政部中區國稅局所屬19個分局稽徵所,自2011年1月起至2015年12月止共5年之贈與稅申報案件月資料,利用獨立樣本t檢定之研究方法,檢定贈與稅申報核定免稅件數、應稅件數及核定應納稅額,在2014年7月開始研議房地合一課徵所得稅制後是否高於研議前。贈與稅核定免稅件數、應稅件數及應納稅額之檢定結果,大屯稽徵所等單位為顯著,表示研議修法後平均贈與稅核定免稅、應稅件數及應納稅額高於研議修法前。 由此可知,房地合一課徵所得稅制研議修法後,核定免稅件數、應稅件數及核定應納稅額在大屯稽徵所等單位有顯著增加,表示房地合一課徵所得稅制開始研議修法,部分民眾為避免未來可能需繳交高額所得稅,有提前規劃贈與之現象。
