What Are the Core Structural Changes in the 2025 Act?
The Income Tax Act 2025 consolidates and restructures direct taxation in India into 536 sections across 23 chapters, replacing the fragmented architecture of the 1961 Act.

How Does the Unified Tax Year Replace Previous Years?
Elimination of Dual Year Confusion
Under the old 1961 Act, taxpayers constantly battled confusing concepts where income earned in a ‘Previous Year’ was taxed in a subsequent ‘Assessment Year’. The 2025 Act completely eliminates this duality by establishing a single, unified Tax Year. Income earned during FY 2026-27 is assessed directly under Tax Year 2026-27, streamlining annual tax planning.
Seamless Calculation for Salaried Workers
Salaried employees often struggled with timing mismatches when employers deducted tax credits. The unified Tax Year aligns salary credits, TDS deposits, and annual returns into one synchronized timeline. This change also complements foundational principles outlined in our detailed study on Assessee & Assessment Year Explained.
Transition Provisions under Section 536

The new framework expands metro city definitions for House Rent Allowance (HRA) exemptions from 4 cities to 8 cities, offering broader tax relief. Furthermore, gift vouchers and employee perquisites receive updated exemption thresholds, such as an increased ₹15,000 limit for certain festive allowances.
Chapter VIII Deductions Overview
Chapter VI-A from the old Act, which housed popular deductions like Section 80C and 80D, is restructured into Chapter VIII under sections 122 to 154. While section numbers change, the core deductions under the new tax act remain accessible for taxpayers opting for the old tax regime.
How Do Tax Rates and Slabs Compare in Old vs New Acts?
