On 1 April 2026 the Income-tax Act, 2025 replaced the Income-tax Act, 1961 — the first full rewrite of India’s income tax law in sixty-five years. It did not change what you owe. Rates, slabs, regimes, deductions and exemptions all carried over untouched, and the Income Tax Department says plainly that the new Act “does not impose any new tax”. What changed is the language, the numbering, one piece of vocabulary you will meet the moment you file, and one genuinely new provision that is currently being argued in the Supreme Court.
A law that governs every rupee of income in the country was replaced this year, and for most people the correct response is to do nothing. That is not a criticism. It was the stated design goal: the Income Tax Department describes the exercise as simplification, not modification of substantive tax law, so that continuity and certainty survived the rewrite.
Which leaves an odd gap between how big the change sounds and how much of it you will feel. Worth separating the two, because the coverage mostly has not.
The Income-tax Act, 2025 is a rewrite of how the law is written, not of what it charges. If your salary, investments and deductions are unchanged, your tax for the year is unchanged. The three things that genuinely differ are a new word for the year you are taxed on, a complete renumbering of every section, and an explicit power to search digital accounts.
The Act came into force on 1 April 2026 and applies from Tax Year 2026-27 onward. The rewrite cut the statute by roughly a third and reorganised what remained.
| Income-tax Act, 1961 | Income-tax Act, 2025 | |
|---|---|---|
| Sections | 819 | 536 |
| Chapters | 47 | 23 |
| Rules | 511 | 333 |
| Forms | 399 | 190 |
| Schedules | 14 | 16 |
| Tax rates and slabs | Unchanged | |
| Deductions and exemptions | Unchanged | |
| PAN, TAN, accounting period | Unchanged | |
Schedules went up rather than down, which is the tell for what this exercise actually was. Long narrative provisos were pulled out of the running text and re-expressed as tables and formulas; explanations that used to hang off the end of a section were folded into it. Fewer words, more structure.
The 1961 Act ran on two clocks. You earned income in the previous year, and it was taxed in the assessment year, which was the following one. Two names for what most people experience as a single event, and the source of a large share of all filing confusion in India.
The 2025 Act collapses them. There is now one term — tax year — defined as the twelve-month financial year, 1 April to 31 March, for which income is computed.
Worked example: which Act applies to which return. Assume a salaried filer with no foreign income and nothing unusual in their affairs.
Income earned between 1 April 2025 and 31 March 2026 falls under the old Act. In the old vocabulary that was previous year 2025-26, assessed in assessment year 2026-27. The return you file in 2026 for that income is an Income-tax Act, 1961 return, on the old section numbers.
Income earned from 1 April 2026 onward falls under the new Act. It is simply Tax Year 2026-27. There is no separate assessment year to name.
So there is a year where both statutes are live at once: you are filing under the old law for last year while earning under the new one. That is not a transition problem anyone has to solve — it resolves itself — but it does explain why two accurate articles can give you different section numbers for the same deduction.
Because this is the part the headlines bury. Under the new Act:
If you were expecting a rewrite of this size to move your take-home pay, it did not. The renumbering is the practical nuisance: a deduction you know by its old section number now lives somewhere else, and any note-to-self, spreadsheet heading or half-remembered rule of thumb that referenced the old number is now pointing at nothing.
One provision is not a renumbering. Section 247 sets out search and seizure powers, and it expressly extends them past physical premises and physical documents into what the Act calls virtual digital space — defined at section 261(j) as a non-physical space created and accessed through computers, and covering social media accounts, online investment accounts, remote and cloud servers, email servers and similar platforms. Section 247(1)(b)(iii) also allows an authorised officer to override an access code to a computer system or virtual digital space where the code is not made available.
How much of that is genuinely new is contested, and the disagreement is not a detail. The Finance Ministry’s position, and reporting following it, is that comparable powers already existed under section 132 of the 1961 Act and that the new text mainly updates the language for a digital environment. Legal commentary disagrees: SCC Online’s analysis argues section 132 was confined largely to physical searches, and that extending it to cloud accounts and adding a code-override power is a substantive expansion rather than a restatement.
Both readings are argued in good faith by people who have read the statute. What is not in dispute is the text itself, and three separate things follow from it.
The Chief Justice’s own framing at that hearing is the fairest summary available: “At present, there is only an apprehension. Let us see how the law is implemented over time.” Which is to say the statutory power is real, the limits the government describes are also real, and whether the safeguards hold is genuinely unresolved rather than rhetorically unresolved.
This is the same reading problem as the UPI rule changes, where a discussion paper circulated for months as though it were a notification. A power that exists on paper, a limit the government asserts, and a court that has not ruled are three different states, and collapsing them into one headline is how “the taxman can now read your email” ends up in a family group chat.
Very little, and specifically:
The rewrite is real and mostly invisible, which is the best available outcome for a project of this size. The risk it creates is not financial but informational: for the next year or two, a great deal of confident tax writing will be numbered against a statute that no longer applies, and the only reliable way to tell is to check the source.
There is a quieter point underneath section 247, though, and it is not about tax. The law now names email accounts, cloud storage and online trading accounts as places that hold your financial life — because they do. That was true long before the Act said so. Most people’s complete financial record already lives in a mailbox they have never audited, spread across alerts from banks, brokers and card issuers that nobody reads in aggregate.
The practical response to that is not to panic about search powers. It is to know what is in there. That is the whole argument for net worth tracking as a habit rather than an annual scramble, and it is why the method of access matters as much as the fact of it — an app that reads transaction alerts without SMS permission sees your spending without ever touching an OTP. Scope is the whole of the safety argument, whether the reader is a tax officer or an app you installed.
No. The rewrite did not change tax rates, slabs, regimes, deductions or exemptions, and the Income Tax Department states that the new Act does not impose any new tax. The Department describes the exercise as simplification rather than modification of substantive tax law, so that continuity and certainty survived. If your income and investments are the same as last year, your liability is the same. What changed is how the law is written and numbered.
A tax year is the twelve-month financial year, 1 April to 31 March, for which your income is computed. It replaces the old two-clock system, where income earned in the previous year was taxed in the following assessment year. There is now one term instead of two. Income earned from 1 April 2026 onward is simply Tax Year 2026-27, with no separate assessment year to name alongside it.
Only during a duly authorised search or survey, not as routine practice. Section 247 expressly extends search and seizure powers to virtual digital space, reported to include email, social media, cloud servers, online banking and trading accounts and crypto holdings. The Finance Ministry clarified in February 2026 that this creates no new blanket powers and cannot be used for routine assessment or data mining, though legal commentators dispute how much of it is genuinely new. A Supreme Court challenge is pending.
The old one, for income earned up to 31 March 2026. The Income-tax Act, 2025 came into force on 1 April 2026 and applies from Tax Year 2026-27 onward, so income earned before that date is still governed by the Income-tax Act, 1961 and its section numbers. This is why both statutes are effectively live at once right now, and why tax articles currently disagree about section numbers.
No to both. Your PAN and TAN continue unchanged, with no reapplication or fresh registration required, and the Income Tax Department states that taxpayers need not change their accounting year or financial statements. The financial year remains 1 April to 31 March. The administrative machinery you already deal with carries over intact; it is the statute underneath it that was rewritten, not your registration.
The new Act names email accounts, cloud storage and online trading accounts as places that hold your financial life, because that is where it is. TLDR Money reads the transaction alerts your bank already sends you — read-only, from Gmail, never your SMS inbox — and turns them into what you spent, what you own, and how far you are from the date your money covers your life.
Scoped, read-only access is the entire safety argument. An app that cannot see your OTPs cannot leak them.
