Article 25

①In the case where a domestic corporation has revaluated its assets to increase their book value, the amount of the increase is excluded from gross profits, when calculating the amount of income of the domestic corporation for each business year.

②In the case where, as an order on the confirmation of a reorganization plan has been rendered with regard to its assets, a domestic corporation has revaluated its assets in accordance with the provisions of the Corporate Reorganization Act (Act No. 154 of 2002) or the Act on Special Measures for the Reorganization Proceedings of Financial Institutions (Act No. 95 of 1996) or has revaluated its assets otherwise as specified by Cabinet Order to increase their book value, the amount of the increase is included in gross profits, when calculating the amount of income for the business year containing the date of the revaluation, notwithstanding the provisions of the preceding paragraph.

③In the case where an order on the confirmation of a rehabilitation plan has been rendered for a domestic corporation or any equivalent event as specified by Cabinet Order has occurred, when the domestic corporation evaluates the value of its assets as specified by Cabinet Order, the amount specified by Cabinet Order as a valuation gain on the assets (excluding those specified by Cabinet Order as unsuitable for recording a valuation gain) is included in gross profits, when calculating the amount of income for the business year containing the date of any of such events, notwithstanding the provisions of paragraph (1).

④In the case where the domestic corporations referred to in the preceding two paragraphs are group tax sharing corporations, the provisions of the preceding two paragraphs do not apply to shares of or capital contributions to another group tax sharing corporation (excluding a corporation specified by Cabinet Order as a corporation not subject to the provisions of Article 64-5 (Aggregation of Profits and Losses) and the group tax sharing parent corporation) held by those domestic corporations.

⑤In the case where the provisions of paragraph (1) were applied, with regard to the assets whose increased value due to revaluation was not included in gross profits, it is deemed that the book value of the assets has not increased, when calculating the amount of income for each business year after the business year containing the date of the revaluation.

⑦Even in the case where a tax return has been filed without a detailed statement of the valuation gain (in the case where there is any valuation loss, without a detailed statement of the valuation gain or a detailed statement of the valuation loss) or without valuation gain-related documents (in the case where there is any valuation loss, without valuation gain-related documents or valuation loss-related documents), the district director of the tax office may apply the provisions of paragraph (3), when they find any unavoidable grounds for the person's failure to make entries of such a statement or to attach such documents.

⑧Beyond what is provided for in the preceding three paragraphs, necessary matters concerning the application of the provisions of paragraphs (1) through (4) are specified by Cabinet Order.
