The Income-tax Act, 2025 (Act No. 30 of 2025) supersedes the Income-tax Act, 1961 and came into force on 1 April 2026. This first part of our five-part series explains the structural reform: how the law has been reorganised, why the change matters, and what it means in practice. It is, by the Government's own stated intent, primarily a structural, drafting and simplification exercise that largely preserves core taxation principles unless expressly changed. 01 What changed structurally? Quick summary card Old law Income-tax Act, 1961 New law Income-tax Act, 2025 (Act No. 30 of 2025) Nature Consolidation, simplification and restructuring Effective date 1 April 2026 (save as otherwise provided) Extent The whole of India Structure 23 chapters, 536 sections, 16 schedules Major concept change "Tax year" replaces "previous year" and "assessment year" Impact Easier navigation, cleaner drafting, better compliance understanding 02 Why a new structure was needed Short answer: over six decades, the 1961 Act accumulated repeated amendments, inserted provisions, provisos, explanations and dense cross-references that made it hard for ordinary taxpayers and even professionals to follow. The 2025 Act presents the same broad tax policy in a more logical, readable and consolidated form. The Income-tax Act, 1961 was a sound statute, but time was unkind to its structure. Each Finance Act added, deleted, or qualified provisions. Sections sprouted sub-clauses; explanations were layered upon provisos; and a single rule could only be understood by chasing references across several chapters. The result was a law that was correct in substance but fragmented in form. The Income Tax Department has stated the intent plainly: the new Act aims to simplify statutory language, improve structural clarity, reduce interpretational disputes, align drafting with modern legislative standards, and enhance voluntary compliance. It does not impose any new tax. To achieve readability, explanations and provisos have been folded into the main text of sections, tables and formulas replace verbose narrative, obsolete provisions have been removed, and cross-references have been made more direct. A practical example: a student, employee, CA or lawyer should now be able to trace the journey of income, that is, the charging provision, the heads of income, exemptions and deductions, computation, rates and rebates, TDS and advance tax, return filing, assessment and then penalties, in a far more logical and sequential flow than before. 03 Income-tax Act, 1961 vs Income-tax Act, 2025 Swipe sideways on the table to see all columns. Point of comparison Income-tax Act, 1961 Income-tax Act, 2025 Practical meaning Law design Built in 1961, then reshaped by decades of amendments Re-drafted as a single consolidated code One coherent document instead of layered patches Language Verbose, with archaic phrasing in places Simpler, plainer drafting Easier to read without expert translation Chapter arrangement Fragmented over time Regrouped into 23 chapters in a logical sequence Provisions sit where readers expect them Use of provisos Numerous standalone provisos Many provisos integrated into the main text Fewer detours while reading a section Use of explanations Frequent separate "Explanations" Explanations merged into the section body where possible The rule and its meaning sit together Previous year & assessment year Two parallel year concepts Discontinued in favour of a single concept Removes the dual-year confusion Tax year Not used Single 12-month "tax year" within a financial year One year to learn, report and assess against Schedules 14 schedules 16 schedules Rate and procedural detail moved into structured schedules Compliance navigation Heavy cross-referencing More direct references and tabular layout Less time spent locating the right rule Litigation impact Ambiguity fuelled disputes Clearer drafting intended to reduce disputes Fewer interpretational grey areas over time Section counts: the 1961 Act had 819 sections; the 2025 Act has 536.

They represent the qualitative difficulty of navigating each Act and convey only the direction of change. 1961 (illustrative) High — 2025 (illustrative) Lower — 05 How income flows through the Act One of the clearest benefits of the restructuring is sequence. The new Act tends to place provisions in the order a taxpayer actually experiences them, so the law reads like the lifecycle of income rather than a scattered index. Income arises ↓ Classify income (heads of income) ↓ Apply residential status and scope ↓ Apply exemptions and deductions ↓ Compute total income ↓ Apply rates and rebates ↓ TDS or advance tax ↓ Return filing ↓ Assessment and compliance ↓ Appeal or recovery, if required In the 2025 Act this journey broadly tracks the chapter order: basis of charge, incomes not included, computation under each head, aggregation and set-off, deductions, rebates and reliefs, determination of tax in special cases, returns, assessment, then collection and recovery, refunds, penalties, offences and miscellaneous matters. 06 Chapter map of the new Act The 23 chapters can be grouped into a handful of conceptual blocks. The cards below describe the kind of provisions a reader will find, grouped by theme rather than reciting every section. Foundations Preliminary & definitions Short title, extent, commencement and the definitions, including the new definition of "tax year". Charge Basis of charge Charge of income-tax, scope of total income, residence in India and income deemed to accrue or arise. Exclusions Income not in total income Incomes excluded from total income, including provisions for political parties and electoral trusts. Computation Heads of income Salaries, house property, profits and gains of business or profession, capital gains and other sources. Attribution Clubbing & aggregation Income of other persons included in your income, plus unexplained credits, investments and expenditure. Losses Set-off & carry forward Set-off within and across heads, and rules for carrying losses forward in various situations. Relief Deductions Deductions for payments, incomes and other categories used in computing total income. Relief Rebates & reliefs Rebates, relief on arrears, and double taxation relief through agreements with foreign countries. Anti-avoidance Anti-avoidance & GAAR Transfer pricing, arm's length price, and the General Anti-Avoidance Rule, retained as before. Special tax Tax in special cases Special rates, MAT and AMT, non-residents, pass-through entities, and the new tax regime including section 202. Administration Tax administration Income-tax authorities, jurisdiction, search and seizure, survey and powers to call for information. Compliance Return of income PAN allotment, filing and processing of returns, verification, self-assessment and updated returns. Compliance Assessment Inquiry before assessment, faceless assessment, income escaping assessment and block assessment of search cases. Special persons Certain persons & NPOs Firms, AOPs, HUFs, representative assessees and the regime for registered non-profit organisations. Dispute Appeals, revision & ADR Appeals to the Commissioner, Tribunal, High Court and Supreme Court, revision and advance rulings. Collection Collection & recovery Deduction and collection at source (TDS, TCS), advance tax, recovery, and interest and fees in certain cases. Refunds Refunds Claims for refund, persons entitled, limitation and interest on refunds. Enforcement Penalties Penalties for under-reporting, misreporting, failures to deduct or collect, and reporting defaults. Enforcement Offences & prosecution Wilful evasion, false statements, offences by companies and HUFs, and trial by special courts. Miscellaneous Miscellaneous Service of notice, authorised representatives, schemes, rules, removal of difficulties and repeal & savings (section 536). Reference Schedules Sixteen schedules carrying rates, procedural detail and structured tables referred to by the sections. Grouping is conceptual and based on the arrangement of clauses in the Act. Individual section numbers are not exhaustively listed. 07 The "tax year" explainer Direct answer: a tax year is a period of twelve months within a financial year. It replaces both the "previous year" and "assessment year" of the 1961 Act with a single reference. Income earned from 1 April 2026 to 31 March 2027 relates to Tax Year 2026-27 . Earlier system (1961) Previous Year + Assessment Year Income of one financial year was assessed in the next, creating two years to track for the same income. New simplified reference (2025) Tax Year A single 12-month period aligned with the financial year. The "assessment year" term is discontinued. Income from 1 April 2026 to 31 March 2027 → Tax Year 2026-27 The tax year corresponds to the old "previous year". Income of a tax year continues to be assessed after the end of that year, exactly as before, so no change to accounting periods or financial statements is required. A tax year can be shorter than a financial year, for example where a new business is set up part-way through the year: a business set up on 1 December 2026 has a tax year running from 1 December 2026 to 31 March 2027. Why does this reduce confusion? Under the old structure, beginners, employees and students routinely mixed up which year they were filing "for" and which year they were filing "in". Aligning the tax year with the financial year removes that dual-year ambiguity, making the timeline intuitive for anyone learning the system for the first time. 08 The pattern behind the new Act 01 Cleaner sequencing Provisions follow the natural lifecycle of income, from charge to assessment to recovery. 02 Shorter navigation route Fewer detours: integrated provisos and direct references shorten the path to the rule you need. 03 Reduced scattered drafting Related concepts are consolidated rather than spread across distant sections and explanations. 04 More tabular presentation Tables and formulas replace dense narrative, for example presumptive taxation consolidated into one section. 05 Continuity of core principles The default new regime, faceless schemes, GAAR, PAN and TAN all continue. The substance largely endures. 09 Practical impact by audience Students A logical chapter order makes the subject teachable as a flow, not a maze of cross-references. Employees The single tax year and simpler language make salary, TDS and return timelines easier to follow. CA & CS students Cleaner structure aids exam preparation, though section numbers must be re-learned against the new map. Practising CAs Less time tracing provisos and references; tabular drafting speeds up day-to-day research and advice. Lawyers Clearer drafting is intended to reduce interpretational disputes, while transitional rules preserve old positions. Founders Easier to grasp the compliance lifecycle, with continuity for existing options, approvals and registrations. Finance teams Existing PAN, TAN and faceless frameworks continue, so process disruption is minimal during transition. Taxpayers Lower compliance friction and reduced dependence on expert interpretation for routine matters. 10 Clickable glossary Tap a term to see its meaning.

What is the biggest structural change? Show answer The reorganisation of the law into 23 chapters, 536 sections and 16 schedules with integrated provisos and simpler drafting, changing how the law is read and navigated rather than its core substance. 2. What does "tax year" mean? Show answer A period of twelve months within a financial year. It replaces both the "previous year" and "assessment year", aligning with the financial year. For example, 1 April 2026 to 31 March 2027 is Tax Year 2026-27. 3. Does the new Act automatically mean all tax rates changed? Show answer No. The 2025 Act is mainly a structural and simplification reform and imposes no new tax. Rate changes are made through the annual Finance Acts. 4. Why were chapters reorganised? Show answer To present provisions in a more logical, coherent sequence after decades of amendments had fragmented the 1961 Act, reducing cross-referencing and interpretational disputes. 5. Who benefits from simplified drafting? Show answer Everyone who reads the law: students, employees, taxpayers, CA, CS and CMA professionals, lawyers, founders and finance teams, through lower compliance friction. 13 Transition checklist & summary Note that the new Act applies from tax years beginning on or after 1 April 2026. Treat earlier years (before 1 April 2026) as still governed by the 1961 Act. Re-map familiar 1961 section numbers to their 2025 counterparts (Part 2 of this series). Confirm existing options, approvals and registrations carry over under section 536. Continue using PAN, TAN and faceless schemes as before. Track the annual Finance Act for any rate or slab changes, separately from structure. Download-style summary box Income-tax Act, 2025 = Act No. 30 of 2025; in force 1 April 2026; extends to whole of India. Structure: 23 chapters, 536 sections, 16 schedules. "Tax year" replaces "previous year" and "assessment year". 1961 Act repealed but preserved for earlier years via section 536. Primarily a structural and drafting reform; no new tax imposed by the restructuring. 14 Do not misunderstand this reform Not Not merely a rate change document. The Act does not exist to change slabs. Rates continue to be set by the annual Finance Acts. Not Not only for CAs. Students, employees, founders and ordinary taxpayers all benefit from clearer drafting and the single tax year. Not Not a wipe-out of 1961 principles. Core concepts, the default new regime, GAAR, faceless schemes, PAN and TAN largely continue, with transitional savings for old years. Why Why it still matters. The structural change alters how the law is read, taught, searched and applied, which is precisely where most everyday friction lived. FinEdge by EduLaw FinEdge by EduLaw Finance. Tax. Law.

It is Act No. 30 of 2025, a statute that consolidates and amends the law relating to income-tax in India. It replaces the Income-tax Act, 1961 and reorganises the law into 23 chapters, 536 sections and 16 schedules with simpler, more integrated drafting. When did it come into force? It came into force on 1 April 2026, save as otherwise provided in the Act. The Income-tax Act, 1961 stands repealed from that date, although it continues to govern tax years beginning before 1 April 2026. How many chapters does it have? Twenty-three chapters, running from Preliminary and Basis of Charge through to Miscellaneous provisions and the repeal and savings clause. How many sections does it have? 536 sections, reduced from 819 sections in the 1961 Act, along with 16 schedules. What is "tax year"? A tax year is a period of twelve months within a financial year. It replaces both "previous year" and "assessment year". Income earned from 1 April 2026 to 31 March 2027 relates to Tax Year 2026-27. It can be shorter than a financial year when a new business or source of income begins mid-year. Is the 1961 Act fully replaced? It is repealed from 1 April 2026, but not erased. Its provisions continue to apply to tax years beginning before that date and to pending or connected proceedings, through the transitional rules in section 536, which also applies section 6 of the General Clauses Act, 1897 to cover unforeseen situations. Does this change tax slabs? No. The 2025 Act is primarily a structural, drafting and simplification reform and does not impose new taxes. Slabs and rates continue to be set through the annual Finance Acts. The default new tax regime carries over (from section 115BAC of the 1961 Act to section 202 of the 2025 Act). Why is the structure important? Because the reform is mainly about form. Provisos and explanations are merged into the main text, tables and formulas replace verbose narrative, and provisions are sequenced logically. This is intended to lower compliance friction and reduce interpretational disputes. How does it help students? A cleaner sequence and simpler language let students learn tax law as a logical flow, from charge to assessment, instead of memorising scattered cross-references. How does it help professionals? Reduced cross-referencing, consolidated provisions and tabular drafting cut research time. Existing approvals, registrations, circulars, PAN, TAN and faceless schemes continue under the new framework, so transition is largely seamless for routine work. 16 Verified sources Income-tax Act, 2025 (as hosted by the Income Tax Department), incometaxindia.gov.in.
