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.
