The Income Tax Act 1961 served India for 65 years. On 1 April 2026, it was replaced. For HNI families, some things changed materially. Most advisors have not yet walked their clients through what those changes mean.
On 1 April 2026, India's Income Tax Act 1961 — which had governed the country's tax framework for 65 years, through 7,000+ amendments and hundreds of judicial interpretations — was formally replaced by the Income Tax Act 2025. This is not a minor update. It is a structural rewrite.
For HNI families, the significance of this change is not primarily about tax rates — most of the core rates have carried over with modifications. The significance is about structure: the language has changed, the cross-references have changed, the HUF treatment has changed, the trust provisions have changed, and the compliance framework has changed. Structures that were built and documented under the 1961 Act need to be reviewed under the new one.
The government's stated objective in introducing the Income Tax Act 2025 was simplification — cleaner language, consolidated provisions, fewer internal cross-references, and a more logical structure. For the most part, that is what has been delivered. But simplification of language does not mean simplification of substance. Several provisions have changed in ways that matter for HNI families.
"The Income Tax Act 2025 is not a restatement of the 1961 Act in cleaner language. It is a rewrite, with substantive changes embedded in the restructuring. Families whose tax structures were designed under the old Act need an independent review of how those structures hold under the new one."
The treatment of Hindu Undivided Families under the Income Tax Act 2025 consolidates several provisions that were previously scattered across multiple sections of the 1961 Act. The new default tax regime — which was already unfavourable for HUFs in its budget 2024 incarnation — continues under the new Act as the default, with the old regime available on opt-in.
For families that established HUF structures specifically for the tax advantages available under the old regime, the new Act requires a careful review of whether those advantages still materialise. In many cases, the answer is that the HUF structure remains useful — but for different reasons than when it was established, and the ongoing costs of maintaining it need to be weighed against the actual benefits under the current framework.
The capital gains provisions — previously spread across Sections 45 through 55A of the 1961 Act — have been consolidated in the new Act. The consolidation has introduced some definitional changes and clarifications that affect the computation of capital gains, particularly around:
Private family trusts are one of the most commonly used wealth structuring tools for Indian HNI families. The taxation of trusts under the new Act has been restructured, and the interaction between trust income, beneficiary taxation, and the new default regime creates scenarios that need to be mapped specifically for each trust structure.
The key question for families with existing trusts: does the trust structure continue to achieve the tax efficiency it was designed for under the 1961 Act? In some cases the answer is yes with minor adjustments. In others, the structure may need to be revisited more substantially. The answer depends entirely on how the specific trust was drafted and what provisions it relies upon.
The residency rules under the new Act maintain the general framework from the 1961 Act but with some modifications to the deemed residency provisions. For Indian families with members settled abroad — or founders and promoters who spend significant time outside India — the residency determination and its tax consequences need to be reviewed under the new Act's specific language.
The new Act introduces some changes to the compliance and reporting framework. The specific reporting obligations for high-value transactions, the documentation required for certain deductions, and the process for assessments and appeals have all been restructured. For HNI families, the practical implication is that the compliance calendar and documentation protocols that were built under the 1961 Act need to be reviewed and updated for the new framework.
It is worth being clear about what the new Act has not changed, to avoid unnecessary anxiety. The core tax rates — on income, on long-term capital gains from listed equity, on dividends — have not changed materially. The fundamental architecture of Indian taxation — the distinction between resident and non-resident, between capital income and business income, between individual and HUF assessment — continues under the new Act. The probate requirement for Hindus, Buddhists, Sikhs, and Jains under Section 213 of the Indian Succession Act has also been repealed, which simplifies estate administration for families with wills.1
The new Act is a restructuring of the framework, not a revolution of the principles. What it requires is not panic — it is a methodical review of whether existing structures continue to work as intended under the new language.
The Income Tax Act 2025 is now the governing framework for every Indian family's tax planning. Structures, documents, and advisory relationships that were built under the 1961 Act need to be validated under the new one. For most families, this review will confirm that existing structures remain effective with minor adjustments. For some, it will surface changes that are worth making now — before a transaction or an assessment forces the issue.
The cost of the review is a few hours of advisory time. The cost of not doing it is the risk that a structure you have relied on for years no longer achieves what you designed it for — under a law that has now been in force for three months.
