The document proposes several changes to tax laws regarding amalgamation, demerger, and slump sales of business undertakings between companies. For amalgamation, it proposes relaxing the shareholder approval requirement from 90% to 75% value of shares. For demerger, it proposes defining demerger and making it tax neutral subject to certain conditions. It also proposes tax treatment for transfers of various assets and costs like losses, depreciation, R&D expenditure in amalgamation and demerger. For slump sales, it proposes treating gains above 36 months as long term capital gains taxed at 20% versus normal rates for shorter periods.
