Introduction
As of April 1, 2026, India has implemented one of its most significant tax reforms since independence. The government has repealed the Income Tax Act, 1961 and replaced it with the Income Tax Act, 2025.
This reform simplifies tax laws, improves clarity, reduces litigation, and strengthens digital compliance. Now, let’s understand all the major changes in a structured and practical manner.
1. Structural & Compliance Overhaul
Introduction of “Tax Year”
First, the government has eliminated the confusing system of Previous Year and Assessment Year. Instead, it has introduced a single concept called the Tax Year.
Now, income earned between April 1, 2026, and March 31, 2027, will be referred to as:
Tax Year 2026–27
As a result, taxpayers can understand and report income more easily.
Redesigned Tax Forms
Additionally, the government has renamed key tax forms:
- Form 16 → Form 130
- Form 16A → Form 131
- Form 26AS → Form 168
Therefore, taxpayers and professionals must update their compliance practices.
2. Filing Due Dates (Tax Year 2026–27)
The government has also rationalized and extended due dates to improve compliance efficiency.
| Category | Applicable Forms | Due Date |
|---|---|---|
| Salaried / Pensioners / Passive Income | ITR-1, ITR-2 | July 31, 2026 |
| Non-Audit Business & Professionals | ITR-3, ITR-4 | August 31, 2026 |
| Tax Audit Cases (Firms & Individuals) | ITR-3, ITR-5 | October 31, 2026 |
| Domestic Companies | ITR-6 | October 31, 2026 |
| Transfer Pricing Cases | ITR-6 | November 30, 2026 |
| Belated / Revised Returns | All | December 31, 2026 |
Consequently, taxpayers now get a clearer timeline and more time for accurate filing, especially in non-audit cases.
3. Income Tax Slabs (Tax Year 2026–27)
The New Tax Regime continues as the default system with the following slab structure:
| Taxable Income (₹) | Tax Rate |
|---|---|
| Up to 4,00,000 | NIL |
| 4,00,001 – 8,00,000 | 5% |
| 8,00,001 – 12,00,000 | 10% |
| 12,00,001 – 16,00,000 | 15% |
| 16,00,001 – 20,00,000 | 20% |
| 20,00,001 – 24,00,000 | 25% |
| Above 24,00,000 | 30% |
Zero Tax up to ₹12.75 Lakh
Moreover, the rebate structure has significantly improved:
- Section 87A rebate: ₹60,000
- Standard deduction: ₹75,000
Therefore:
- Up to ₹12 lakh → No tax
- Up to ₹12.75 lakh (salaried) → No tax
This directly benefits middle-class taxpayers.
Marginal Relief Protection
Furthermore, the government ensures fairness by strengthening marginal relief.
Now, if income slightly exceeds ₹12 lakh, the extra tax will never exceed the extra income earned.
4. Major Relief & Deduction Changes
Expanded HRA Metro Cities
The government has expanded the 50% HRA exemption category:
- Delhi, Mumbai, Kolkata, Chennai
- Added: Bengaluru, Pune, Hyderabad, Ahmedabad
Children’s Allowances Increased
- Education Allowance: ₹3,000/month per child
- Hostel Allowance: ₹9,000/month per child
Corporate Gift Limit Increased
- Old: ₹5,000
- New: ₹15,000 per year
Medical Loan Relief Enhanced
- Old: ₹20,000
- New: ₹2,00,000
5. Investment & Transactional Changes
Share Buybacks
Now taxed as Capital Gains instead of deemed dividend.
STT Increased
- Options: 0.15%
- Futures: 0.05%
Sovereign Gold Bonds
- Exemption only for original subscribers
- Secondary market investors → Capital Gains tax applies
Dividend Income

6. Corporate & Professional Updates

- No further MAT credit allowed
- Functions as final tax
TCS Rationalization
Flat 2% TCS on scrap, minerals, and liquor.
LRS Changes
- Education/Medical (> ₹10 lakh): 2%
- Others: 20%
7. Digital & Compliance Improvements
The government continues to promote digital tax systems:
- Faceless assessments
- Online notices and replies
- Faster refunds
- Pre-filled ITR forms
Thus, compliance becomes faster and more transparent.
8. Old vs New Regime
Old Regime Offers
- Deductions (80C, 80D, etc.)
- HRA, LTA
- Home loan benefits
New Regime Offers
- Lower tax rates
- Higher rebate
- Standard deduction ₹75,000
- Simplified compliance
Therefore:
- Up to ₹12.75 lakh → New regime is generally better
- High deductions → Old regime may be beneficial
Conclusion
The Income Tax Act, 2025 transforms India’s tax system by simplifying compliance, increasing the zero-tax threshold, and introducing a clear Tax Year framework.
Moreover, the revised due dates, improved deductions, and digital systems make taxation more efficient and user-friendly. Overall, this reform promotes clarity, fairness, and ease of compliance for all taxpayers.
