Article 43  If, in any year, a Resident is issued a government subsidy or its equivalent that is meant to be allocated to acquiring or improving Fixed Assets, and the final decision that the Resident need not return the government subsidy or its equivalent has not been reached by December 31 of the relevant year (or by the time of the Resident's death or the start of the Resident's Absence From Japan, if the Resident dies or becomes Absent From Japan partway through the year), an amount equal to the government subsidy or its equivalent is not included in the gross revenue that is used to calculate that Resident's Income in Each Class for the year.

前項の規定の適用を受けた居住者が交付を受けた同項の国庫補助金等の全部又は一部の返還を要しないことが確定した場合には、その国庫補助金等の額のうちその確定した部分に相当する金額は、その国庫補助金等の交付の目的に適合した固定資産の取得又は改良に充てられた金額のうち政令で定める金額を除き、その者のその確定した日の属する年分の各種所得の金額の計算上、総収入金額に算入する。
