One Screen, Two Statutes

A small notice on the e-Filing portal this week is worth pausing on. The department has quietly rolled out an integrated payment module that lets taxpayers pay dues under the Income-tax Act, 1961 for periods up to FY 2025-26 and under the Income-tax Act, 2025 for Tax Year 2026-27 onwards, all from a single interface. The notice on the Income Tax Department portal puts it plainly:

Seamless payments now enabled across both the Income-tax Act, 1961 and the Income-tax Act, 2025.

That word, seamless, does a lot of work. India is running two direct tax statutes in parallel, one for closing out old years and one for opening new ones. Every legal transition of this scale creates a temptation to make the citizen learn the transition too, to force them to pick which Act their payment belongs to, to route them through different portals, different challan formats, different mental models. The interesting bit of engineering here is the opposite instinct: absorb the complexity inside the system so that a person paying a demand from AY 2022-23 and a person paying advance tax for TY 2026-27 use the same three clicks. The citizen does not need to know which statute is doing the arithmetic.

There is a wider lesson for public administration in this. The measure of a good transition is how quickly it becomes invisible to the person on the other side of the counter. Officers see two Acts, two sets of rules, two saving clauses, two mental frameworks running simultaneously. The taxpayer should ideally see one screen. That gap, between the complexity we carry internally and the simplicity we present externally, is where administrative craft lives. It is worth building for. And it is worth defending against every impulse to expose the plumbing.

The Code Goes Live

Somewhere in a finance department of a company, a junior accountant is staring at a payment portal that now asks her to select Tax Year 2026-27 instead of Assessment Year 2027-28. That single drop-down is where the new Income-tax Act, 2025, actually begins. Not on 1 April, when it commenced. On 15 June, when the first advance-tax instalment falls due and a real bank account moves money under a real new statute.

Tax law, like a building, is finished only when somebody walks in.

The first deadline is the real commencement

The Income-tax Act, 2025, has been on the books for months. The Income-tax Rules, 2026, replaced the 1962 Rules from 1 April. Hundreds of FAQs have circulated. None of that is the test. The test is the 15 June advance-tax instalment for Tax Year 2026-27, the first time a taxpayer estimates a year's liability under the new code and pays fifteen percent of it.

That is when the law moves from print to pay-in. Until then, every conversation about the new Act has been a rehearsal. From 15 June, the choreography is live.

Two statutes, one tax year

There is a peculiar transition reality that gets understated. The 1961 Act stands repealed from 1 April 2026, but the repeal does not disturb anything relating to tax years before that date. Assessments, appeals and proceedings for earlier years continue under the old Act. The advance-tax instalment due in March 2026 for FY 2025-26 was governed by the old law. The instalment due on 15 June 2026 is governed by the new one.

So the department, and every CFO of any scale, is now running two statutes simultaneously: one for past income, one for current income. From inside any large tax administration, this is the un-televised reality. A transition is not a date; it is a multi-year overlap, where the same officer handles a 2023-24 reassessment under the old code in the morning and a 2026-27 advance-tax compliance under the new code after lunch. The simplification on paper does not eliminate that doubling of cognitive load. Only time does.

The small print of a clean statute

The new Act is shorter, cleaner and more readable than the 1961 Act after six decades of grafts and provisos. But cleanness creates its own friction at the implementation layer. "Previous year" has become "tax year". Section numbers have shifted: advance tax now sits in Sections 403 to 410 rather than the familiar Section 208 onwards. Form 16 is now Form 130. Form 3CEK is now Form 173. Form 26AS is now Form 168.

None of this changes any substance. All of it changes muscle memory. Every payroll system, every ERP, every accountants-office macro, every internal departmental tutorial, every taxpayer's mental shorthand must be rewritten. The headline simplification will be felt only after that rewriting is done. The cost of clarity is paid up front, in transition friction; the dividend comes back later, in compliance ease. Reformers tend to celebrate the first. Only practitioners feel the second.

An administration learning in public

I think the more interesting question is what a new code does to the administration that runs it. A tax department is, in operational terms, a very large rule-execution machine. When the rulebook changes, every loop in that machine must be re-instructed. The portal must accept new minor-head codes. Notices must cite new sections. Officers must learn to draft orders in the new language without slipping back into the 1961 cadence they have known their whole careers. Helpline scripts must be rewritten. Internal training becomes, in effect, an ongoing exam.

This is where productivity either materialises or evaporates. If the first advance-tax cycle runs smoothly, if challans clear, refunds reconcile, mismatches are caught early, then taxpayer confidence in the new regime is established for the next decade. If it is messy, every news cycle of the next few months will be about glitches, and a reform that is substantively sound will be remembered as operationally rocky. The legislative work is over. The implementation game has just begun.

A small proposal for the transition window

One concrete suggestion. Through the first full tax year under the new Act, every taxpayer-facing communication, intimation, notice, demand, refund order, should carry the equivalent old-Act section in parentheses next to the new one. A demand under Section 405 of the 2025 Act should read "(corresponding to Section 234C of the 1961 Act)". This is not a dilution. It is a translation layer.

It would cost the department almost nothing. It would save tens of thousands of taxpayers from a private translation exercise each. It would also reduce the small but real risk of misdescription in appellate orders during cross-over years, where a citation gets stuck between two statutes. Translation layers age well. They quietly disappear once they are no longer needed, leaving a cleaner system behind. The concordance table mapping the old sections with the new one needs to get etched in the muscle memory.

For most taxpayers, 15 June 2026 will feel like any other deadline. For the new Income-tax Act, 2025, it is the day the simulation ends and the actual run begins. Everything written about the new code so far has been on a whiteboard. From that date, it is on the ledger.

After Section 536

The 1961 Act ended quietly. No ceremony, no farewell. A single line in Section 536 of the new statute did the work, and on 1 April a law that had carried India’s direct taxes for sixty-five years was repealed. The Income Tax Act, 2025 is now live: 536 sections, 23 chapters, 16 schedules, down from more than 800 sections and 47 chapters. The headline word is “simplification”. The reality is more interesting, and more difficult, than the headline suggests.

Anyone who has lived inside the 1961 Act for a working lifetime knows that “simplification” is a mild description of what has just happened.

What “simplification” actually changes

The leaner numbers are the easy story. They get repeated in every press release. What they do not capture is the deeper editorial move: provisos folded into the main text, Explanations integrated into the body, and tabular rates and conditions replacing the cottage industry of parsing “Explanation 2 to sub-section (4) of section X” that consumed entire afternoons of an officer’s week.

The unification of “previous year” and “assessment year” into a single “tax year” is the cleanest example. Two financial years to describe one slice of income, with the gap producing systematic confusion in returns, notices and correspondence. Anyone who has tried to explain this dual structure to a first-time taxpayer, or worse to a foreign investor, knows it was always indefensible. Gone. One concept, one period, one number. This sounds trivial. It is not.

Five things actually shift

1. Discoverability

A 536-section Act with consolidated schedules is, for the first time, something a careful non-specialist can navigate. That matters more than the profession has admitted, and it matters enormously for AI. Every retrieval system, every assistant, every chatbot the public sector builds for taxpayers now sits on a cleaner corpus. Anyone who has trained a tax-domain assistant on the 1961 Act knows the specific pain of teaching a model to chase a fifth-level cross-reference into a circular issued in 1987. A flatter statute is easier for humans and easier for machines, in that order.

2. Drafting culture

The bigger contribution may not be the Act itself but the precedent it sets. Government drafting in India has long defaulted to safety through proliferation: another proviso, another Explanation, another sub-clause. The 2025 Act demonstrates, in a statute of national importance, that ruthless consolidation is possible without surrendering legal precision. That lesson needs to travel. GST, Customs, the Companies Act, the FEMA framework: all of them are due the same treatment, and now there is no honest excuse left.

3. The treatment of digital assets

The Act widens the definition of undisclosed income to include virtual digital assets. This is a small line with large implications. A clear statutory hook that earlier had to be assembled, awkwardly, from anti-avoidance rules and circulars now sits inside the main definitional architecture. Crypto investigation is no longer at the margins of the statute. It is inside it.

4. Litigation, slowly

I do not believe clearer text will reduce disputes immediately. For five to seven years, two Acts will run in parallel: pending matters under the old framework, new periods under the new one. The honest expectation is more litigation in the short term, not less, because every transitional provision will be tested in court at least once. The long-term gain is real. It will take the better part of a decade to show up in dispute statistics.

5. The administrator’s reset

Every officer is, in some sense, a new joiner. The institutional memory of the 1961 Act — which sub-section connects to which proviso under which 1985 amendment — is being retired with the statute. That is a generational opportunity for training. It is also a generational risk if training is treated as a formality and officers are left to absorb the new code by osmosis.

The dual-track problem nobody wants to discuss

Section 536 is the cleanest part of this transition. The messy part is everything around it. Assessments for periods up to FY 2025-26 will continue under the 1961 framework. New tax years run under the 2025 Act. Notices, appeals, refunds and recoveries for the next several years will straddle both statutes, often inside the same taxpayer’s file. The new challans are live; the old challans remain in use until FY 2025-26 dues are cleared. A senior taxpayer with an appeal under the old law and a current return under the new one is, in practice, dealing with two governments. He will judge both by the worse experience.

The integrated payment module the e-filing portal now offers, allowing payments across both Acts from a single interface, is a small but telling signal: a unified experience across two statutes is the right design instinct. The same instinct must extend to assessments, faceless proceedings, refunds, grievance handling and the help content the chatbot serves. Otherwise simplification on paper becomes friction in practice, and the public never sees the gain.

The test that matters

The Act is good. Whether it succeeds is a separate question, and the answer will not be visible on 2 April. It will become visible in three places. First, how quickly officers retire 1961-era reflexes — the muscle memory of citing four-level cross-references is hard to unlearn. Second, whether the next Finance Acts resist the temptation to begin re-cluttering this clean statute with new provisos within eighteen months, which is the usual cycle. Third, whether public-facing systems — portals, kar saathi chatbot, helplines, the printed material in field offices — reflect the new structure faithfully, fast. Drafting cannot guarantee any of that. All of it depends on what happens next, inside the administration.

Section 536 ended an Act in a single sentence. The harder sentences are the ones we are about to write.

From your desk to the FM - KarSetu

There is a particular kind of satisfaction — quiet, almost private — that comes from watching something you crafted at your own desk travel all the way up and enter the public domain at the highest level. On 20th March 2026, the Hon'ble Finance Minister of India, Smt. Nirmala Sitharaman, released Kar Setu — the eBook and booklet on Interplay and Transition FAQs from the Income Tax Act, 1961 to the Income Tax Act, 2025.

What Kar Setu Is

India is undergoing one of the most significant legislative transitions in its fiscal history. The Income Tax Act, 1961 — a statute that governed the tax lives of every Indian for over six decades — is being replaced by the Income Tax Act, 2025. This is not a cosmetic rewrite. It is a restructuring of 536 sections, affecting over 700 field offices, tens of thousands of tax officers, and millions of taxpayers and practitioners across the country.

The question that every officer in the field, every chartered accountant advising a client, every taxpayer filing a return would inevitably ask is: What changes? What stays? What do I do differently starting April 2026?

Kar Setu was built to answer that question.

The name itself — Kar Setu, a bridge of duty — was chosen deliberately. This is not a commentary or an academic paper. It is a bridge. A structured, FAQ-based guide that maps the interplay between the old Act and the new, so that the transition is navigable rather than bewildering.

The Four Months Behind It

What the public sees today is a finished product — clean, structured, authoritative. What they don't see is the four months that preceded it.

Sixteen sub-committees were constituted to cover every major area of the Act. Each committee comprised officers who live and breathe these provisions daily — assessment, appeals, penalties, TDS, international taxation, search and seizure, and more. The coordination happened out of the Directorate of Organisation and Management Services (DOMS), CBDT, where I serve as Member Secretary to the Guidance Note Committee for the ITA 2025 implementation.

There were drafts. Many drafts. There were rounds of review where a single FAQ would be debated, reworded, cross-referenced, and debated again. There were late-night iterations where you are staring at Section 247 of the new Act and tracing its lineage back to Section 143(3) of the 1961 Act, making sure the transition guidance is precise enough that a young ITO in a mofussil town can rely on it.

This is the unglamorous work of governance. No stage, no spotlight. Just a desk, a screen, and the knowledge that if you get this wrong, the confusion will cascade across the entire tax ecosystem.

Why This Matters Beyond Tax

I have spent fifteen years in the Indian Revenue Service. I have done transfer pricing investigations, ITAT litigation, international tax advisory, and policy work. I have studied at Columbia and Harvard, advised at the UN, and consulted for the G20. But I will say this plainly: there is something uniquely grounding about building a document that will be used by an Assessing Officer in Dharwad and a Senior Partner at a Big Four firm in Mumbai on the same day, for the same purpose.

Kar Setu is a leveller. It doesn't distinguish between the officer who needs it to process a case and the practitioner who needs it to advise a client. It serves both. That is what public goods are supposed to do.

In an age where we talk endlessly about AI in governance, digital transformation, and technology-led reform, it is worth remembering that sometimes the most impactful thing a government can produce is a well-structured document that answers the right questions clearly. Not an app. Not a dashboard. A document — researched, debated, refined, and released.

The Moment

When the Finance Minister releases something you have been working on for months — something that started as a working file on your desktop, went through committee after committee, was revised at 11 PM on a Thursday, and finally emerged as a polished eBook — there is a moment. It is not dramatic. It is not cinematic. But it is deeply, quietly, satisfying.

You don't need anyone to tell you the work mattered. You know. Because you watched it travel from your desk to the hands of the person who stewards this country's fiscal policy. And now it is in the public domain, serving the people it was always meant to serve.

Kar Setu is live. The bridge is built.
