Big Tax Update: CBDT Revises Rule 128 Under Income Tax Rules 2026

Key Highlights of the Amendment

1. Clarification on Pre-2017 Investments

The amended Rule 128 now explicitly provides that:

  • Any income arising from the transfer of investments made before April 1, 2017, will be treated separately.
  • Such income will not be subject to certain provisions linked with post-2017 arrangements , ensuring relief for taxpayers holding legacy investments.

2. Revised Scope of Chapter XI (GAAR Provisions)

The amendment strengthens the applicability of Chapter XI (General Anti-Avoidance Rules - GAAR) by stating:

  • GAAR provisions will apply to any arrangement, regardless of when it was entered into.
  • However, an exception has been carved out for income arising from investments made before April 1, 2017.

3. Retrospective vs Prospective Balance

The notification brings clarity by:

  • Applying GAAR provisions prospectively on tax benefits arising on or after April 1, 2017
  • While safeguarding income linked to pre-2017 investments, thereby reducing litigation risks and interpretational ambiguity.

Why This Amendment Matters

The update to Rule 128 is significant for taxpayers, multinational entities, and tax professionals as it:

  • Provides certainty on the tax treatment of legacy investments
  • Reinforces the intent and scope of GAAR provisions
  • Helps avoid retrospective tax disputes
  • Aligns with the government’s broader objective of transparent and predictable tax administration

Expert Insight

Tax experts believe that the amendment strikes a balanced approach ensuring anti-abuse rules are effectively applied, while protecting genuine past investments from unintended tax consequences.
