Bookmarking this page might save you the most time of any article in this series. Below is a single, scannable table mapping the Income-tax Act, 1961 section numbers you already know to their Income-tax Act, 2025 equivalents — covering deductions, TDS, capital gains, assessment, search & seizure, MAT, and charitable trusts. Use it as your go-to lookup from 1 April 2026 onward.

Why You'll Need This Table

The Income-tax Act, 2025 renumbers almost every provision of the 1961 Act as part of its restructuring into 23 chapters. While the substance of most provisions is unchanged, the citations you'll encounter in Form 16, investment proofs, TDS certificates, ITR forms, and professional correspondence from 1 April 2026 onward will increasingly reference the new numbering. This table consolidates the mappings covered across our Income-tax Act 2025 series into one quick-reference resource.

⚠ How to use this table: If you see an unfamiliar section number on a document dated on or after 1 April 2026 (Form 16, investment proof, TDS certificate, assessment notice), check this table for the corresponding old section — the underlying rule is very likely the same provision you're already familiar with, just renumbered. For documents dated before 1 April 2026, continue to use the old section numbers.

What's Not in This Table

This table covers the most commonly referenced provisions for individual taxpayers, salaried employees, and small businesses. The Income-tax Act, 2025 renumbers the entire statute — including provisions for international taxation, transfer pricing, specific industry incentives, and procedural/appellate provisions — which are outside the scope of this quick-reference table. For comprehensive section-by-section concordance, refer to the official concordance table (if published by CBDT) or consult a tax professional for matters involving less common provisions.

As CBDT issues further notifications, rules, and forms under the Income-tax Act, 2025, we'll continue to update this reference table. For now, it covers the changes most likely to affect salaried individuals, small business owners, investors, and companies as they transition into Tax Year 2026-27.

Frequently Asked Questions

Is this table a substitute for the official CBDT concordance table?
No. This table is a practical quick-reference covering the most commonly encountered provisions (Chapter VIA deductions, TDS, capital gains, assessment, MAT, and charitable trust registration) based on publicly reported mappings as of June 2026. For comprehensive, authoritative section-by-section concordance — particularly for less common provisions like international taxation, transfer pricing, or specific industry incentives — refer to official CBDT publications or consult a qualified CA.
From when do the new section numbers apply?
The new section numbers under the Income-tax Act, 2025 apply to transactions, income, and compliance obligations arising from 1 April 2026 onward (Tax Year 2026-27). Anything relating to FY 2025-26 (filed as AY 2026-27, due 31 July 2026) continues to use the old Income-tax Act, 1961 section numbers.
Why do some old sections map to multiple new provisions (e.g., capital gains)?
In some areas, like capital gains, the Income-tax Act, 2025 splits what was previously handled within fewer, more complex sections (with many provisos) into multiple cleaner clauses organised by asset type and gain classification (e.g., separate clauses for STCG-equity, LTCG-equity, and LTCG-non-equity). This reflects the broader simplification goal of separating distinct rules into distinct provisions rather than bundling them with cross-referencing provisos.
