The notification, issued on March 31, 2026, assumes significance in the backdrop of the Tiger Global case, which had triggered widespread concerns among foreign investors and tax experts over the scope of grandfathering provisions.
At its core, the amendment to Rule 10U of the Income-tax Rules, 1962 and the corresponding Rule 128 under the Income-tax Rules, 2026 clarifies a critical point: income arising from the transfer of investments made before April 1, 2017, will remain outside the ambit of GAAR, regardless of when the gains are realised.
What triggered the need for clarification
The controversy traces back to the Supreme Court’s interpretation in the Tiger Global case, which examined the interplay between GAAR and grandfathering provisions available to legacy investments—particularly those routed through jurisdictions like Mauritius.
While the tax framework had always intended to protect investments made before April 1, 2017, from GAAR scrutiny, the court held that such protection was not absolute. It was observed that if a tax benefit arose after the GAAR regime came into force, authorities could still invoke anti-avoidance provisions, effectively diluting the grandfathering shield.

This interpretation unsettled investors, especially offshore funds, as it opened the door to potential retrospective taxation and litigation on exits from long-held investments.
What the CBDT has now clarified
The latest amendment decisively addresses this ambiguity.
By refining the language in the rules, the CBDT has now:
- Explicitly excluded income from the transfer of pre-April 1, 2017 investments from GAAR
- Ensured that this protection applies even if gains arise after 2017
- Reinforced that grandfathering is absolute, not conditional
In effect, the tax treatment of such legacy investments is now “ring-fenced,” insulating them from anti-avoidance scrutiny under GAAR.
Riaz Thingna, Partner at Grant Thornton Bharat, noted that the clarification ensures gains accrued up to the cut-off date remain protected, addressing concerns that had emerged after the Tiger Global ruling.
According to him, the move allays fears of retrospective taxation and preserves the original intent behind grandfathering provisions.
A reset of the GAAR vs grandfathering debate
Tax experts say the amendment effectively resets the balance between GAAR and grandfathering.
Sandeep Bhalla, Partner at Dhruva Advisors, explained that under the earlier framework, while pre-2017 investments were ostensibly outside GAAR, a separate provision allowed authorities to examine arrangements yielding tax benefits after that date. This created interpretational overlap, which the Supreme Court leaned on in its ruling.

The revised rules now remove that overlap by clearly carving out such income from GAAR altogether—thereby restoring the intended safe harbour for legacy investments.
Relief for foreign investors and offshore funds
The biggest beneficiaries of this clarification are likely to be foreign portfolio investors, private equity funds, and venture capital firms that made investments into India before April 2017.
These investors had relied on treaty protections—particularly under the India-Mauritius tax treaty—and the assurance that their investments would not be subject to future anti-avoidance scrutiny.
Rohinton Sidhwa, Partner at Deloitte India, pointed out that the controversy in Tiger Global largely centred around the availability of treaty benefits to grandfathered investments. The court had taken the view that GAAR could override such benefits, but the latest clarification effectively corrects that understanding by reinforcing the government’s original promise.
Industry calls it a ‘timely intervention’
Market participants have broadly welcomed the move, calling it a much-needed intervention to restore certainty.
Amit Baid, Head of Tax at BTG Advaya, described the amendment as a “welcome and timely clarification,” noting that it significantly reduces the relevance of the Tiger Global ruling on the specific issue of GAAR grandfathering. While the judgment may still guide broader questions around substance and treaty abuse, its impact on legacy investments is now limited.
Similarly, Sandeep Sehgal, Partner-Tax at AKM Global, said the amendment is largely clarificatory but crucial in removing ambiguity. He added that while the Tiger Global case was driven by indirect transfer provisions, the new rules resolve the interpretational uncertainty regarding how GAAR interacts with grandfathering when tax benefits arise after 2017.
What remains unchanged
Importantly, the amendment does not dilute the broader GAAR framework.
- Investments made on or after April 1, 2017 remain fully subject to GAAR
- Tax authorities retain powers to scrutinise aggressive tax avoidance structures
- The focus on substance over form continues to guide enforcement
This ensures that while legacy investments are protected, the anti-avoidance regime remains robust for newer transactions.
Why this matters for India’s investment climate
Beyond technical tax interpretation, the move carries wider implications for India’s credibility as an investment destination.
Frequent disputes over retrospective taxation have historically weighed on investor sentiment. By stepping in to clarify the rules and align them with original policy intent, the government signals a commitment to tax certainty and stability—a key factor for long-term capital inflows.
The timing of the notification—coming just as global investors reassess emerging market allocations amid geopolitical and economic shifts—adds to its significance.
The bottom line
The CBDT’s latest amendment draws a clear line in the sand: investments made before April 1, 2017, will not be second-guessed under GAAR, regardless of when gains are realised.
By neutralising the ambiguity created by the Tiger Global case, the government has not only resolved a key interpretational issue but also reinforced its commitment to honouring past tax promises.
For investors, especially those holding legacy assets, the message is unambiguous—the rules of the game will not change midway.
