GAAR and Family Trust Restructuring: Where Legitimate Succession Planning Risks Being Recharacterised as Tax Avoidance

Why GAAR Matters to Private Client Work

India's General Anti-Avoidance Rule (GAAR), contained in Chapter X-A of the Income-tax Act, 1961 (and carried forward in substance into the Income-tax Act, 2025), gives tax authorities the power to disregard or recharacterise an "impermissible avoidance arrangement" - broadly, an arrangement whose main purpose is to obtain a tax benefit, and which lacks commercial substance or is not entered into for bona fide purposes. GAAR was designed with corporate and cross-border tax structuring in mind. But its language is broad enough that family succession and trust restructuring, if planned carelessly, can fall within its reach - a risk that is not always front-of-mind for families who see estate planning as a personal, not corporate, exercise.

What Makes an Arrangement "Impermissible"

Under Section 96 of the Act, an arrangement is treated as an impermissible avoidance arrangement if its main purpose is to obtain a tax benefit, and it satisfies at least one of several additional tests: it creates rights and obligations not ordinarily created between parties dealing at arm's length; it results, directly or indirectly, in misuse or abuse of the Act's provisions; it lacks commercial substance, in whole or in part; or it is carried out in a manner not ordinarily employed for bona fide purposes.

The critical phrase for private client work is " lacks commercial substance." A private family trust, by definition, does not need commercial substance in the way a corporate transaction does - its substance is dispositive and protective, not commercial. This creates genuine interpretive uncertainty: a family trust restructuring that has real succession, asset-protection, or governance rationale should not fail the commercial-substance test on its own terms, but a trust that exists solely to fragment income across family members and reduce the family's aggregate tax burden, without any accompanying change in genuine control or purpose, sits far closer to GAAR's target.

Where the Risk Concentrates in Practice

Income-splitting trusts with no real change in control. A discretionary trust that distributes income to lower-tax-bracket family members, while the settlor continues to exercise effective control over the underlying assets and investment decisions in substance, is a structure GAAR is specifically designed to look through. The dispositive language of the trust deed matters less than the actual pattern of control and benefit that plays out after the trust is created.

Trust restructuring timed closely around anticipated tax events. Where a family reorganises its trust structure shortly before an anticipated liquidity event (a business sale, an IPO, a large capital gain), and the restructuring's principal, demonstrable effect is to reduce the tax otherwise payable on that event, the timing itself becomes evidence relevant to the "main purpose" test - even where the family also asserts (accurately, in many cases) that succession planning was a genuine underlying motive.

Layered structures with limited independent economic function. Multiple trusts or holding entities interposed between the family's operating assets and the ultimate beneficiaries, where each layer adds no discernible governance, protective, or succession function beyond tax deferral or reduction, invite exactly the kind of "lacks commercial substance" characterisation GAAR targets.

GAAR's Procedural Safeguards - and Their Limits

GAAR is not meant to apply automatically or informally. Its invocation requires the tax officer to refer the matter to a Principal Commissioner or Commissioner, who must be satisfied GAAR provisions are applicable, and - where the taxpayer objects - a reference to the Approving Panel, a body intended to provide an independent check before GAAR is finally invoked. There is also a monetary threshold below which GAAR is generally not invoked for routine, low-value arrangements. These safeguards meaningfully reduce (though do not eliminate) the risk of GAAR being applied casually to ordinary family estate planning.

However, the safeguards operate procedurally, not by carving out succession planning as a category. A family trust structured with genuine tax minimisation as one motive among several remains within GAAR's potential scope; the safeguards determine how carefully the question gets examined, not whether the question can be asked at all.

The Practical Advisory Distinction

The single most useful discipline in this area is separating two categories of family trust motive that are often blurred in client conversations:

• Genuine succession and governance purpose - protecting a beneficiary who cannot yet manage assets, consolidating family business control across generations, ring-fencing assets from an individual family member's business or personal risk, providing for a dependent with specific long-term needs. These purposes exist independently of any tax outcome, and a trust structured to achieve them, even if it also produces tax efficiency as a byproduct, stands on materially stronger ground.

• Tax-outcome-driven restructuring dressed in succession language - where the trust deed recites succession objectives, but the family's own conduct (continued effective control by the settlor, no genuine change in who benefits or when, timing tied tightly to a tax event) tells a different story.

Documenting the first category properly - recording the actual family circumstances that motivated the structure, ensuring the trustee genuinely exercises the discretion the deed confers rather than mechanically following the settlor's continued instructions, and avoiding restructuring timed suspiciously close to tax events - is the practical work that keeps legitimate estate planning outside GAAR's target zone.

The Broader Point

GAAR does not make family trusts inherently risky, and the vast majority of properly motivated, properly administered family trusts are in no realistic danger of GAAR scrutiny. The risk is concentrated specifically at the intersection of aggressive tax outcomes and thin non-tax rationale - and the advisory task is ensuring a family's genuine succession planning is not left exposed simply because it was drafted without attention to how it would read if a tax authority ever asked why the structure exists.
