§ 233
Chapter XIII — Determination Of Tax In Special Cases

Amalgamation and demerger

Income-tax Act, 2025

Business owners should note that when companies amalgamate or demerge, specific rules apply to the tonnage tax scheme. If the amalgamated company is a qualifying company, it may be subject to the tonnage tax scheme. Key points to consider include:

  • exercising the option for tonnage tax scheme within three months of amalgamation approval
  • applying the scheme for the unexpired period of the longest option
  • computing income from operating qualifying ships according to other Act provisions if certain conditions are not met
These rules aim to clarify the tax implications of company restructuring.
