二代健保補充保費制度，是在各方關注與不斷的爭議下通過立法，並於民國102年正式實施，最主要是基於財務面的考量及各階層間的公平合理性。惟整個補充保費的徵收是否能達到預期目標，及其徵收的過程是否簡便易懂，這些議題都是本研究欲探討的重點。 本研究以記帳士事務所為個案討論對象，由於其服務的客群以中小企業為主更由於成本考量並未編制專業人員處理二代健保補充保險費扣費事宜，在事務所為維持與顧客間的長期配合及提高服務品質之原則下，使二代健保補充保費的徵收，無形中增加記帳士事務所的業務範圍，卻難收取額外增加的處理費用。根據本研究之討論結果，建議相關主管單位，二代健保補充保費應採「家戶總所得」徵收，以縮減複雜難懂的扣費手續，希冀研究結果能提供所屬單位日後之改善依據。 The supplementary premium system of 2nd Generation NHI was legitimated formally implemented in the year of 2013 under great concerns and constant dispute.
