New Income Tax Act 2025 Key Changes

The New Income Tax Act 2025: Everything You Need to Know

A Historic Tax Reform — 60 Years in the Making

After decades of patchwork amendments, India finally has a brand-new tax code. The Income Tax Act, 2025 officially came into effect on April 1, 2026, replacing the Income Tax Act, 1961, which had accumulated over 800 sections, countless provisos, and layers of complexity.

Whether you’re a salaried individual, a business owner, or a startup founder, this article breaks down the key changes that affect you directly — updated with developments through September 2026.

Latest Update — September 2026

  • The Act is already amended. The Finance Act, 2026 amended the Income-tax Act, 2025 with effect from April 1, 2026 itself — always verify section references against the latest text.
  • New Income-tax Rules, 2026 in force. Notified on March 20, 2026, the new Rules carry just 333 rules and 190 forms (down from 511 rules and 399 forms under the 1962 Rules). A second tranche of statutory forms rolled out on June 30, 2026.
  • Form ITR-BN introduced. The Income-tax (Third Amendment) Rules, 2026 (notified July 27, 2026) introduced Form ITR-BN for return filing in search and requisition cases.
  • FAST-DS disclosure window open until December 31, 2026. Small taxpayers can regularise undisclosed foreign assets and income — an effective 60% (30% tax plus an equal penalty) for undisclosed assets/income up to ₹1 crore, or a flat ₹1 lakh fee for already-taxed or non-resident-acquired assets up to ₹5 crore — with immunity from further tax, penalty, and prosecution under the Black Money Act, 2015.
  • Remittances under the scanner. The Income-tax Department is examining outward remittances of about ₹1.29 lakh crore, with 394 entities and 36 certifying professionals under verification — Form 15CB certification standards are in focus.

1. Structural Simplification — From 819 Sections to 536

The single biggest achievement of the new Act is its massive structural simplification:

  • Sections: Reduced from 819 to 536
  • Chapters: Consolidated from 47 to 23
  • Language: Obsolete provisions removed; plain English drafting adopted

This isn’t just a cosmetic change — it directly reduces litigation, ambiguity, and compliance costs for taxpayers and professionals alike.

2. The “Tax Year” Concept — Goodbye Assessment Year

One of the most celebrated changes is the abolition of the dual “Previous Year” and “Assessment Year” system. The new Act introduces a unified “Tax Year” concept.

What this means: You earn income in Tax Year 2026-27, and you file your return for Tax Year 2026-27 under Section 52. No more confusion about which year is the “assessment” year.

This simplification is especially beneficial for cross-border transactions, NRIs, and businesses operating across multiple jurisdictions.

3. Virtual Digital Assets — Clearer Rules for Crypto

The new Act provides clearer definitions for virtual digital assets (cryptocurrencies, NFTs, tokens), and empowers tax authorities to access “virtual digital spaces” — including online accounts and servers — during search and seizure proceedings.

If you hold or trade in crypto assets, compliance under the new Act is non-negotiable. TDS on VDA transfers is now under Section 393(1) Table 1 Sl. 4 (formerly 194S).

4. NIL-TDS Certificates — A Welcome Relief Under Section 247

Taxpayers with no tax liability — including retirees, students, and small investors — can now apply for NIL-TDS certificates in advance under Section 247. This prevents unnecessary tax deductions at source and eliminates the need for refund claims.

5. Refund Eligibility for Belated Returns

Previously, filing a belated or revised return often meant losing the right to claim refunds. Under the new Act, taxpayers who file belated or revised returns under Section 52 are now eligible to claim refunds — correcting a long-standing injustice.

6. Updated Allowance Limits Under IT Rules 2026

The accompanying Income Tax Rules, 2026 have updated several exempt allowance ceilings:

AllowanceOld LimitNew Limit
Children’s Education Allowance₹100/month/child₹3,000/month/child
Hostel Allowance₹300/month/child₹9,000/month/child
Free Meals₹50/meal₹200/meal
Non-Cash Gifts₹5,000/year₹15,000/year

7. Tax Slabs — No Change (Confirmed as of September 2026)

The Act focuses on structure, not rates. Five months into the new Act, the new tax regime remains the default under Section 202 and rates are unchanged. Under the enhanced Section 156 rebate (formerly 87A, up to ₹60,000), taxable income up to ₹12 lakh is effectively tax-free. With the standard deduction of ₹75,000, salaried individuals earning up to ₹12.75 lakh pay zero tax.

8. Key Section Number Changes You Must Know

The new Act has completely renumbered all major provisions:
