所得税法施行規則(しょとくぜいほうしこうきそく)

Chapter I Calculation of Income in Each Class (Articles 39-2 to 40-2)

The law as Ministerial Order Partially Amending the Regulation for Enforcement of the Income Tax Act (Ministry of Finance Order No. 17 of 2026) leaves it, with the words it changes marked.

The main text is read a page at a time: a chapter to a page, and a long chapter in runs of articles. The whole main text, and the supplementary provisions and appended tables this amendment changes. Those it leaves untouched are on the page for the text in force.

How the changes are shown

Underlined: words the amendment adds. A bar: where it removes words. Struck through: the words it removes.
