On August 11, 2025, the Lok Sabha passed the Income Tax (No. 2) Bill, 2025 — the most sweeping overhaul of India's direct tax law since 1961. The new Act does not change tax rates or slabs. What it does is simplify, reorganise and modernise a law that had grown to over 800 sections and had become extremely difficult to navigate even for professionals.
The new Income Tax Act 2025 comes into effect from April 1, 2026 — meaning it applies to income earned in Tax Year 2026-27 and beyond. For FY 2025-26, the old Act still applies.
The new Income Tax Act 2025 does not change any tax slabs, rates or deductions. The same New Regime and Old Regime slabs apply. What changes is how the law is structured, how compliance works, and how forms are numbered. Your tax liability stays the same.
Why Was the 1961 Act Replaced?
The Income Tax Act 1961 was enacted for a very different economy. Over 64 years of amendments, it grew from a manageable law into a complex maze of 819 sections, 47 chapters, thousands of cross-references and hundreds of circulars. Filing a return required navigating multiple overlapping provisions. Even chartered accountants spent hours just locating the right section.
The new Act cuts this down to 536 sections in 23 chapters — a reduction of nearly 35%. More importantly, it has been rewritten in plain language, eliminating the archaic legal phrasing that made the old Act hard to understand.
What the New Act Changes — 6 Key Things
1. Simpler Structure — 536 Sections Instead of 819
The entire Act has been reorganised for logical flow. Related provisions are grouped together. Cross-references have been eliminated where possible. A taxpayer or professional can now find the relevant provision in one place without jumping across chapters.
2. "Tax Year" Replaces "Previous Year" and "Assessment Year"
One of the most confusing aspects of the old law was the distinction between Previous Year (year of earning) and Assessment Year (year of filing). The new Act introduces a single concept — "Tax Year" — which is the financial year in which income is earned and assessed. This eliminates a major source of confusion for taxpayers.
3. Digital-First and Faceless Administration
The new Act extends faceless assessment to more processes including scrutiny, reassessment and appeals. Mandatory e-notices become the norm for most communications. This significantly reduces physical office visits and the associated harassment and bias. All documentation, filings and responses will be digital by default.
4. Forms Are Renumbered
All the familiar tax forms have been renumbered under the new rules. This is important for salaried employees to know:
| Old Form Name | New Form Name | Purpose |
|---|---|---|
| Form 16 | Form 130 | Salary TDS Certificate from employer |
| Form 26AS | Form 168 | Annual Tax Credit Statement |
| Form 16A | Renumbered | TDS certificate for non-salary income |
| Form 12BB | Form 124 | Investment declaration to employer |
The content and purpose of these forms remains the same — only the numbers change. HR and payroll teams will need to update their systems accordingly.
5. Stronger Taxpayer Protections
The new Act introduces mandatory notices before enforcement actions, stricter timelines for tax department responses and tighter rules around reassessment. This protects taxpayers from arbitrary notices and prolonged scrutiny. An officer cannot open a case without clear documented grounds.
6. Cryptocurrency and Virtual Digital Assets Formally Recognised
The 1961 Act was never designed for digital assets. The new Act formally classifies cryptocurrencies and other Virtual Digital Assets as taxable capital assets. The taxation mechanism remains the same (30% flat tax) but the legal basis is now clear, reducing ambiguity and potential disputes.
What Does NOT Change
- Tax slabs and rates — Same New Regime and Old Regime rates continue
- Standard deduction — Still ₹75,000 (New Regime) and ₹50,000 (Old Regime)
- Section 80C, 80D deductions — All deductions under Old Regime continue
- 87A rebate — Same ₹60,000 rebate for income up to ₹12 lakh (New Regime)
- Your previous filings — Not affected. The new Act applies only to Tax Year 2026-27 onwards
When your employer sends the investment declaration form in April 2026, it will be called Form 124 instead of Form 12BB. The information you need to provide is exactly the same — your HRA details, 80C investments, home loan interest, etc. Do not be confused by the new form number.
The Draft Income Tax Rules 2026 — What Is Still Pending
The Act itself is passed. But the accompanying Income Tax Rules 2026 — which contain the detailed procedural guidelines — were released as a draft in February 2026 for public feedback. These rules cover HRA calculation, perquisite valuation, form specifications and more. The final rules will be notified before April 1, 2026.
Some of the most significant proposals in the draft rules — particularly around HRA for new cities and revised allowance limits — are covered in detail in our companion articles below.
