Why India Needed a New Income Tax Act

India’s original Income-tax Act, 1961 was a product of its time. Written for a largely agricultural and manufacturing economy, it was lean and navigable. Over the following six decades, however, successive Finance Acts layered on amendments, provisos, exceptions, cross-references, and explanations until the statute ballooned to over 800 sections spread across 47 chapters — a dense thicket that even experienced chartered accountants found difficult to navigate for routine filings.

The problems were structural, not cosmetic. Ambiguous drafting fuelled competing interpretations, feeding multi-year case backlogs and high litigation costs. Key compliance provisions — particularly TDS rules — were scattered across dozens of sections indexed by income type, making it near-impossible to get a holistic view. Meanwhile, India’s economy had become digital: e-commerce, platform income, virtual digital assets, and cross-border digital flows were being taxed under a framework rooted in paper-era structures.

Introduced as the Income-tax (No. 2) Bill, 2025 and approved by the Lok Sabha on August 11, 2025, the new Act received Presidential assent on August 21, 2025, and came into force on April 1, 2026 alongside the new Income Tax Rules, 2026 notified by the Central Board of Direct Taxes (CBDT).

Key Facts at a Glance

Major Structural Changes in the Income Tax Act 2025

The “Tax Year” Concept Replaces Previous Year + Assessment Year

One of the most consequential conceptual changes is the elimination of the confusing dual-year terminology. The 1961 Act required understanding two parallel concepts: the “Previous Year” (when income was earned) and the “Assessment Year” (when that income was taxed). The 2025 Act replaces both with a single unified Tax Year — a 12-month period from April 1 to March 31 — that aligns Indian tax terminology with global standards.

Language Simplification and Structural Reorganisation

The 2025 Act transforms legal readability in three ways. First, explanations and provisos — previously appended as afterthoughts — have been incorporated into the main text of sections. Second, verbose narrative provisions have been replaced with tables and formulas wherever quantification is involved. Third, redundant and obsolete provisions have been removed entirely, and cross-references have been made clearer and more direct.

Faceless and Digital-First Administration Extended

The 2025 Act extends the faceless assessment regime to more processes, including scrutiny, reassessment, and appeals. Mandatory e-notices become the norm for most communications with the Income Tax Department. Authorities now have explicit statutory power to access cloud storage, email servers, and social media accounts during investigations — a recognition that financial evidence increasingly lives in digital spaces rather than physical files.

Unified TDS Framework Under Sections 392 and 393

Under the 1961 Act, TDS provisions were scattered across dozens of sections — Section 192 for salaries, 194A for interest, 194C for contractors, and so on. The 2025 Act consolidates all TDS provisions under Section 393 (non-salary TDS) and Section 392 (salary TDS), making it far easier for deductors to understand their obligations from a single reference point. A unified self-declaration form replaces the separate Form 15G and Form 15H.

HRA Metro Cities Expanded

The list of metro cities eligible for the higher House Rent Allowance (HRA) exemption has been widened. Bengaluru, Hyderabad, Pune, and Ahmedabad now join the existing metros (Delhi, Mumbai, Chennai, Kolkata), offering greater HRA tax relief to employees in India’s fastest-growing urban centres.

Stock Buybacks Now Taxed as Capital Gains

In a significant policy shift, stock buybacks are no longer treated as deemed dividends but are now taxed as capital gains in the hands of the shareholder. This change impacts both promoters and retail investors and aligns India’s buyback taxation more closely with the economic substance of the transaction.

Income Tax Slabs Under the New Regime — Tax Year 2026-27

The Income-tax Act, 2025 retains the same slab structure introduced in Budget 2025. No new rates have been introduced. Below is the full slab schedule under the default new tax regime for individual taxpayers for Tax Year 2026-27:

A 4% Health and Education Cess applies on total tax. Surcharge applies on income above ₹50 lakh. The Section 157 rebate ensures zero tax liability for resident individuals with taxable income up to ₹12 lakh (maximum rebate ₹60,000). For salaried taxpayers, the standard deduction of ₹75,000 further raises the effective zero-tax limit to ₹12.75 lakh.

Old Tax Regime Slabs (Still Available, Optional)

Old vs New Tax Regime — Which Suits You?

The 2025 Act retains both regimes. The new regime remains the default; taxpayers must actively elect the old regime. The choice hinges on how many deductions you can legitimately claim.

Income Tax Act 2025 vs 1961 — Comprehensive Comparison

TDS Consolidation — What Changed Under Section 393

The TDS overhaul is arguably the most practically impactful reform for HR and payroll teams. Under the 1961 Act, a payroll officer had to navigate Section 192 (salaries), 193 (interest on securities), 194A (other interest), 194C (contractors), 194H (commission), and dozens more — each with its own threshold, rate, and compliance nuance.

For bank interest specifically, banks can no longer treat CBDT circulars as advisory — they must strictly follow clarified definitions and thresholds to avoid penalties. The TDS-free limit for bank interest remains ₹40,000 (₹50,000 for senior citizens) across all branches of the same bank in a financial year.

Digital Economy and Virtual Digital Asset Provisions

The 2025 Act is the first Indian income tax legislation to natively integrate the digital economy rather than bolt it on through amendments. Virtual Digital Assets (VDAs) — which includes cryptocurrency, NFTs, and other blockchain-based tokens — are now defined and referenced throughout the Act rather than appearing as standalone additions.

Taxation of VDAs remains unchanged at 30% flat on gains, with a 1% TDS on transfers. However, the native integration provides greater legal certainty and reduces scope for interpretation disputes. The abolition of the Equalisation Levy on digital non-resident operators aligns India with evolving global trade norms and simplifies cross-border digital commerce.

• VDA gains taxed at 30% flat (unchanged from 1961 Act amendments)
• 1% TDS on VDA transfers under Section 393
• No set-off of VDA losses against other income
• Equalisation Levy on digital operators abolished
• Explicit statutory authority for cloud, email, and social media access during investigation
• Digital evidence natively recognised and admissible throughout the Act

Impact Analysis by Taxpayer Category

Transition Framework — How the Old and New Acts Co-exist

Section 536(2)(j) of the 2025 Act ensures that all CBDT circulars, notifications, and approvals issued under the 1961 Act remain valid as long as they do not conflict with the new Act. Existing faceless assessment schemes continue without interruption. PAN, TAN, and other administrative frameworks carry forward unchanged.
