Comparative Study of Provisions of Income Tax Rules 2026 and Income Tax Rules 1962 By Taxmann – 2026 April Edition

Comparative Study of Provisions of Income-Tax Rules 2026 & Income-Tax Rules 1962 serves as an essential transition reference. It reproduces the operative text of both sets of Rules side by side, word for word, and highlights every deletion, simplification, modification, and new insertion within the text itself—effectively making the legislation its own annotation. All amendments notified up to 31^st March 2026 in both sets of Rules have been incorporated, establishing this as the authoritative record of the Rules framework at the point of transition. This book serves as the procedural companion to Taxmann’s Comparative Study of Provisions of Income-Tax Act 2025 & Income-Tax Act 1961, which maps the substantive legislative transition at the level of the Act. Together, they offer comprehensive top-to-bottom coverage of what has changed, what has been retained, and what is new—across both the parent statute and the subordinate rules that provide it with operational force. Neither volume is complete without the other.

This book is designed for practitioners and professionals who must work across both legislative frameworks simultaneously—either to advise clients on transition-period compliance, to interpret provisions that straddle both regimes, or to understand the precise scope of change introduced by the 2026 Rules. The primary readership includes:

• Chartered Accountants, Tax Advocates, and Company Secretaries advising on income-tax compliance, assessments, and appeals
• Corporate Tax and Legal Teams handling transfer pricing, safe harbour elections, TDS/TCS obligations, and return filings under the transitional framework
• Tax Administrators and Revenue Officers requiring a structural reference for the new Rules
• Researchers, Academics, and Students engaged with the legislative transition from the 1961/1962 framework to the 2025/2026 regime

The Present Publication is the 2026 Edition, incorporating all amendments notified upto 31^st March 2026 in both Income-tax Rules 1962 and Income-tax Rules 2026. It is edited/authored by Taxmann’s Editorial Board, with the following noteworthy features:

• [Word-to-Word Two-Column Parallel Comparison] The core of the book is a provision-by-provision textual comparison in a split-column format. The operative text of the 1962 Rules appears on the left; the corresponding provision under the 2026 Rules appears on the right. Every sub-rule, clause, sub-clause, item, sub-item, proviso, and Explanation is aligned directly opposite its counterpart, enabling precise, granular comparison without cross-referencing across separate volumes
• [Visual Change Identification System] A two-layered typographic coding system makes every legislative change immediately identifiable without reading both columns in full:
  • Bold + Strikethrough in the 1962 Rules column – The language has been deleted or modified in the 2026 Rules
  • Bold text in the 2026 Rules column – The language is newly inserted, simplified, or changed relative to the 1962 Rules
  • This system allows the reader to scan quickly for the nature and extent of change at the sub-provision level
• [Cross-Reference Tables—Rules] Two dedicated tables map the renumbering of rules across the two sets of Rules in both directions:
  • Table 1 | Rules of Income-Tax Rules 1962 → Corresponding Rules of Income-Tax Rules 2026
  • Table 2 | Rules of Income-Tax Rules 2026 → Corresponding Rules of Income-Tax Rules 1962
  • Each entry shows both the rule number and the rule heading under both frameworks, enabling practitioners to locate the 2026 equivalent of any 1962 rule instantly, and vice versa.
• [Cross-Reference Tables—Forms] An equivalent pair of tables maps forms prescribed under both sets of Rules:
  • Table 3 | Forms of Income-Tax Rules 1962 → Corresponding Forms of Income-Tax Rules 2026
  • Table 4 | Forms of Income-Tax Rules 2026 → Corresponding Forms of Income-Tax Rules 1962
  • These tables are particularly valuable for compliance officers and fiduciaries who need to identify which new form corresponds to a legacy form they are familiar with
• [Provisions Without Corresponding Rules] A dedicated section at the front of the book lists all provisions of the Income-Tax Rules, 2026 that have no corresponding provision in the Income-Tax Rules 1962—i.e., entirely new rules introduced by the 2026 framework. This section allows practitioners to identify, at a glance, the net legislative additions
• [Migration of Provisions from the Income-Tax Act] A separate reference section identifies provisions that were previously embedded in the Income-Tax Act 1961 or the Income-Tax Act 2025, which have now been migrated into the Income-Tax Rules 2026. This addresses a structural feature of the legislative reorganisation—the movement of certain computational and procedural provisions from the Act itself into subordinate legislation—which has direct implications for interpretation and applicability

The book is organised into three principal sections:

• Section I | Reference Tables and Transitional Mapping — This section opens the book and functions as the navigation backbone. It contains all four cross-reference tables (Rules 1962 → 2026; Rules 2026 → 1962; Forms 1962 → 2026; Forms 2026 → 1962), the section identifying provisions migrated from the Acts into the Rules, and the complete list of new 2026 Rules with no 1962 counterpart. This section enables rapid look-up and transitional mapping without entering the main comparative text
• Section II | Comparative Study of Provisions — The core of the book. Rules are presented in the order of the 1962 Rules, with the corresponding 2026 Rule positioned alongside. Where a 1962 Rule maps to multiple 2026 Rules (or vice versa), all relevant provisions are displayed. Where a 1962 Rule has no 2026 counterpart (i.e., the rule has been omitted or subsumed), this is indicated by the absence of a corresponding column entry. The book opens with a standalone section covering provisions of the 2026 Rules that have no corresponding 1962 Rule, ensuring those entirely new provisions are not buried within the comparison
• Each comparative entry preserves the exact legislative text, including provisos, Explanations, tables, and sub-items, with the visual coding system applied throughout to highlight changes
