New Income-tax Act takes effect, replacing 1961 law

The Income-tax Act, 2025 comes into force from today, retiring the six-decade-old 1961 Act in a clean re-write that leaves tax policy untouched.

What happened

• From 1 April 2026, the Income-tax Act, 2025 is the operative direct-tax statute of India, displacing the Income-tax Act, 1961 that had governed the country's income tax for more than six decades.
• The new Act was passed by Parliament on 12 August 2025 and received Presidential assent on 21 August 2025; the gap to the 1 April 2026 commencement let the administration prepare forms, systems and the rule-book.
• To operationalise the statute, the Income-tax Rules, 2026 were notified by the Central Board of Direct Taxes (CBDT) on 20 March 2026, carrying simplified and standardised forms.
• The stated aim is to simplify the language and structure of direct-tax law — shorter sections, plainer drafting, tables in place of dense provisos — without changing the underlying tax policy.
• Crucially, this is not a rate change and not a new slab regime: rates, slabs, exemptions and the policy architecture continue as legislated; what changes is the wrapper, not the tax.
• Because commencement is pegged to the start of a financial year, the Act applies cleanly to assessment from FY 2026-27 onward, avoiding a mid-year split in the law that taxpayers must obey.

Background & context

India's income tax has, since Independence, run on a single primary statute at a time. The Income-tax Act, 1961 replaced the older Income-tax Act of 1922 and became the spine of direct taxation — defining who is a taxpayer, what counts as income across the five heads (salary, house property, business or profession, capital gains, and other sources), how residency is determined, and how the Income-Tax Department assesses, collects and recovers tax. Over six decades it was amended every year through successive Finance Acts, layered with provisos, explanations and cross-references until even practitioners struggled to read a single chain of conditions end to end. The 2025 Act is the response to that accumulated complexity: a consolidation and re-drafting exercise that keeps the policy intact while making the text navigable.

This sits inside a wider decade-long push to recodify India's foundational laws in plain, modern form. The three criminal codes — the Indian Penal Code, the Code of Criminal Procedure and the Indian Evidence Act — were replaced from 1 July 2024 by the Bharatiya Nyaya Sanhita, Bharatiya Nagarik Suraksha Sanhita and Bharatiya Sakshya Adhiniyam. The Income-tax Act, 2025 is the direct-tax counterpart of that same instinct: retire a colonial-era-descended, heavily-amended statute and re-issue the law in a cleaner architecture. The distinction worth holding is that the criminal-law overhaul did change some substantive provisions, whereas the income-tax exercise is presented expressly as a structural simplification with policy held constant.

The administering chain is unchanged and is examinable in its own right. Direct taxes are levied by the Union and administered by the Income-Tax Department, which functions under the Central Board of Direct Taxes (CBDT). The CBDT is a statutory body constituted under the Central Boards of Revenue Act, 1963, and it is the apex body for direct-tax administration and policy. The CBDT in turn sits within the Department of Revenue in the Ministry of Finance. Its sibling at the same level is the Central Board of Indirect Taxes and Customs (CBIC), which handles customs, central excise and GST administration — a pairing UPSC has tested as a "match the body to its remit" item. It is the CBDT that notified the Income-tax Rules, 2026, exercising the rule-making power the parent Act delegates to it.

It helps to place income tax precisely within the tax system. Taxes are split into direct and indirect. A direct tax is borne by the same person on whom it is levied — income tax and corporate tax are the leading examples, and their burden cannot be shifted to someone else. An indirect tax (GST, customs, excise) is collected from one party but ultimately passed on to the final consumer, so its burden is shiftable. Income tax is the most familiar direct tax, and it is this body of law — not GST or customs — that the Income-tax Act, 2025 recodifies. Direct taxes are also generally progressive (the rate rises with income), which is one reason the policy architecture of slabs and exemptions is treated as sensitive and was deliberately left untouched by this exercise.

Compared with a typical annual Finance Act, the difference in kind is the point. A Finance Act is the budget vehicle: it tweaks rates, slabs, exemptions and thresholds for a single year and amends the standing income-tax law at the margins. The Income-tax Act, 2025 does the opposite — it does not change rates at all; it replaces the entire standing statute with a re-drafted text. One is an annual policy adjustment; the other is a once-in-generations structural consolidation. Holding the two apart is the cleanest way to defeat a "this changed your tax slab" misreading of the event: nothing in a citizen's tax liability changes by reason of the new Act alone.

For Prelims

• Entity: Income-tax Act, 2025 — the new primary direct-tax statute of India, in force from 1 April 2026.
• Replaces: the Income-tax Act, 1961 (which itself had replaced the Income-tax Act, 1922).
• Legislative timeline: passed by Parliament 12 August 2025 · Presidential assent 21 August 2025 · commenced 1 April 2026.
• Operationalising subordinate legislation: Income-tax Rules, 2026, notified by CBDT on 20 March 2026, with simplified and standardised forms.
• Stated objective: simplify language and structure (plainer drafting, fewer provisos, more tables) without altering underlying tax policy.
• Administering authority: Central Board of Direct Taxes (CBDT) — statutory body under the Central Boards of Revenue Act, 1963 — within the Department of Revenue, Ministry of Finance.
• The regulatory chain: Parliament enacts the Act → President assents → CBDT (under the Department of Revenue) frames and notifies the Rules → the Income-Tax Department administers assessment and collection.
• Nature of the reform: a recodification / re-drafting of direct-tax law, not a Finance-Act-style change to rates, slabs or exemptions.

Why it matters

The problem the Act addresses is readability and compliance friction, not the level of taxation. Six decades of annual amendment turned the 1961 Act into a document where a single answer often required chasing a section into a proviso, then an explanation, then a cross-referenced sub-section elsewhere in the statute. That complexity has real costs: higher compliance burden for ordinary taxpayers, more room for interpretive disputes and litigation, and a steeper learning curve for officers and professionals. A statute that is easier to read is easier to obey and easier to administer, which is the governance case for a clean re-drafting that deliberately leaves the policy alone so that no taxpayer faces a substantive surprise on day one.

The timing also matters. By commencing the Act on the first day of a financial year and by notifying the Rules a fortnight earlier on 20 March 2026, the government gave the system a clean changeover rather than a disruptive mid-year switch — taxpayers, deductors and the department all move to the new text at the natural boundary of the assessment cycle. Holding rates and policy constant while changing only the structure is the safeguard that turns a large legislative event into a low-shock transition: continuity of revenue and of taxpayer obligations, with the gain concentrated in clarity. For the wider reform agenda, a successful recodification of direct-tax law strengthens the template — consolidate, simplify, plain-draft — that the criminal codes began.
