Income Tax Act, 2025

The Income Tax Act, 2025 is India's primary direct tax statute, enacted by Parliament to replace the six-decade-old Income-tax Act, 1961 effective 1 April 2026. Comprising 536 sections across 23 chapters and 16 schedules, it modernises direct tax administration through simplified statutory phrasing, a unified tax year framework, and consolidated withholding tax sections.

Background and Enactment of the Income Tax Act, 2025

In July 2024, the Ministry of Finance announced a comprehensive review of India's direct tax architecture. Over six decades, the legacy statute had accumulated more than 4,000 amendments, conflicting provisos, and redundant sunset clauses. This statutory density caused persistent litigation, high compliance costs, and administrative uncertainty for corporate taxpayers.

To establish a concise and readable code, the government introduced the Income-tax Bill, 2025 in the Lok Sabha in February 2025. Following review by a 31-member Parliamentary Select Committee chaired by Baijayant Panda, the Ministry introduced the revised Income-tax (No. 2) Bill in August 2025. Parliament passed the legislation, and President Droupadi Murmu granted assent on 21 August 2025 as Act No. 30 of 2025. The statute took effect on 1 April 2026, repealing the Income Tax Act, 1961.

Key Structural Reforms in the Income Tax Act, 2025

The Income Tax Act, 2025 retains fundamental direct tax policies while overhauling statutory structure, terminology, and procedural mechanisms.

Transition from Assessment Year to Unified Tax Year

The legacy statute operated on a dual timeline: the Previous Year (earning year) and the Assessment Year (filing year). This split caused recurring confusion, challan mapping errors, and portal validation rejections.

The Income Tax Act, 2025 replaces this dual concept with a single Tax Year. Income earned between 1 April 2026 and 31 March 2027 is reported directly under Tax Year 2026-27. This change aligns Indian tax records with global accounting standards and simplifies enterprise ledger reconciliations.

Consolidation of TDS Framework under Section 392 and Section 393

Under the 1961 statute, withholding provisions were scattered across dozens of standalone sections from 192 through 194T and 195, each with separate thresholds and filing nuances.

The Income Tax Act, 2025 consolidates withholding rules into two primary sections:

• Section 392: Governs tax deduction at source on salaries, consolidating deduction calculations and tax regime elections into one workflow.
• Section 393: Serves as the master section for non-salary withholding across three tables: Table 1 for payments to residents, Table 2 for payments to non-residents, and Table 3 for payments to any person.

Statutory reporting is similarly streamlined. Deductors report salary withholding quarterly in Form 138 (replacing Form 24Q) and domestic non-salary deductions in Form 140 (replacing Form 26Q). For practical guidance, read our insights on implementing the new income tax act 2025.

Streamlined Deductions and Modernised Schedules

The statute replaces dense legal exceptions with structured tables and algebraic formulas. Deductions formerly claimed under Chapter VI-A (such as Section 80C) are reorganised under Section 123 read with Schedule XV, retaining the ₹1,50,000 limit for eligible taxpayers choosing the optional tax regime. Obsolete export incentives have been removed, and statutory rules for Virtual Digital Assets (VDAs) are incorporated directly into the primary law.

Operational Impact and Transition Rules for Enterprises

Withholding Cut-Off Dates and Accounts Payable Configuration

The Central Board of Direct Taxes (CBDT) clarified that TDS liability arises at the earlier event of credit or payment. Transactions credited or paid on or before 31 March 2026 follow the 1961 Act. Payments or credits on or after 1 April 2026 require deduction under Section 393.

Finance teams must update ERP software to map legacy section codes to Section 393 payment rows. Automated AP automation software prevents misclassifications and vendor mismatches during monthly tax accounting.

Payroll Alignments and Employee Declarations

Payroll engines must calculate withholding under Section 392, aligning employee declarations with Section 123 and Schedule XV. Disciplined payroll compliance ensures accurate deductions and prompt Form 138 quarterly reporting.

Section 536 Repeal and Savings Provisions

Section 536 serves as the transition bridge. Across 22 sub-clauses, it ensures that prior assessments, rectifications, and appellate proceedings continue under the 1961 Act. It also preserves the uninterrupted carry forward and set off of accumulated business losses and unabsorbed depreciation.

Frequently Asked Questions

Does the Income Tax Act, 2025 introduce higher tax rates?

No. The Income Tax Act, 2025 focuses on structural and procedural modernisation rather than increasing tax rates. Corporate tax slabs, individual income tax rates, and surcharge tables continue to be determined annually through the Finance Act passed by Parliament.

How does the unified Tax Year simplify enterprise accounting?

The unified Tax Year eliminates the confusing distinction between Previous Year (earning period) and Assessment Year (reporting period). For example, income earned between 1 April 2026 and 31 March 2027 is directly referred to as Tax Year 2026-27 in all books, returns, and tax challans.

What happens to pending tax assessments under the 1961 Act?

All scrutiny assessments, penalty notices, reassessments, and appellate matters initiated for periods prior to 1 April 2026 continue under the procedural provisions of the Income-tax Act, 1961. Section 536 of the new statute provides comprehensive savings rules to protect pending proceedings.

Which forms replace Form 24Q and Form 26Q for TDS reporting?

From 1 April 2026 onwards, deductors report salary withholding using Form 138 (replacing Form 24Q) and resident non-salary withholding using Form 140 (replacing Form 26Q). TCS statements are filed in Form 143 (replacing Form 27EQ).
