Transition to the Income Tax Act, 2025
The Income Tax Act, 2025 is India’s new direct tax law that will replace the decades-old Income Tax Act, 1961 from 1 April 2026. Reorganising the tax code into 23 chapters and 536 sections (down from 700+), the new Act simplifies compliance, removes obsolete provisions, and facilitates user-friendly, digital tax administration.
While the fundamental tax system and rates remain largely stable, the framework has been modernised. Below are the 12 most critical updates taking effect from the financial year 2026-27 (with filings starting under the new system from 1 April 2026).
12 Key New Income Tax Rules & Changes
1. ITR Filing Due Dates Extended
Good news for non-audit taxpayers! From FY 2026-27 onwards, the due date for filing returns in forms ITR-3 and ITR-4 has been extended from 31 July to 31 August. Please note that the deadlines for ITR-1 and ITR-2 (31 July) and tax audit cases (31 October) remain unchanged.
2. More Time to File a Revised Return
Taxpayers now get additional time to correct errors in their submissions. The deadline for filing a revised return has been extended from 9 months to 12 months, allowing revisions up to 31 March of the assessment cycle. However, an additional fee may apply if the revised return is filed after 31 December. The due date for belated returns remains unchanged.
3. TCS Rates Simplified
To reduce refund bottlenecks, the TCS (Tax Collected at Source) rate structure has been simplified:
- TCS on the sale of scrap, minerals, and alcoholic liquor for human consumption is increased from 1% to 2%.
- TCS on tendu leaves and LRS remittances for education and medical treatment is reduced from 5% to 2%.
- For overseas tour packages under LRS, the dual rates of 5% and 20% are replaced with a flat 2% TCS rate, with no threshold limit.
4. No Change in Income Tax Slabs
There are no changes in the income tax slab rates under the New Tax Regime for FY 2026-27. Crucially, taxpayers opting for the new tax regime can claim a tax rebate of up to ₹60,000 under Section 87A, making annual income up to ₹12 lakh effectively tax-free.
5. Higher STT for F&O Traders
Securities Transaction Tax (STT) rates on Futures & Options (F&O) trades have been increased, leading to slightly higher transaction costs for active derivative traders.
Revised STT Rates (Effective April 1, 2026)
| Particulars | Current Rate | New Rate (From Apr 1, 2026) |
|---|---|---|
| Sale of Options (Premium) | 0.10% | 0.15% |
| Sale of Options (Intrinsic Value) | 0.125% | 0.15% |
| Sale of Futures | 0.02% | 0.05% |
6. Buyback Tax Rules Changed
Share buybacks will undergo a major tax transition. Previously, buyback distributions were taxed at the corporate level as deemed dividends. From 1 April 2026, buyback proceeds will be taxed in the hands of the investor as Capital Gains, altering tax calculations for equity investors.
7. Sovereign Gold Bonds Exemption Limited
Capital gains tax exemption on the maturity of Sovereign Gold Bonds (SGBs) will now be restricted exclusively to investors who subscribed to the bonds during their initial issue. SGBs acquired through the secondary market will no longer enjoy this maturity tax exemption.
8. Easier TDS for Property Buyers
When purchasing immovable property from a Non-Resident Indian (NRI), buyers can now deduct and deposit TDS using a simple PAN-based challan, completely eliminating the requirement to obtain a Tax Deduction and Collection Account Number (TAN).
9. No Interest Deduction on Dividend Income
Taxpayers will no longer be permitted to claim deductions for interest expenses incurred to earn dividend income or income from mutual fund units, ensuring a cleaner tax treatment for investment income.
10. New Income Tax Forms Introduced
The Income Tax Rules, 2026 introduce revamped and simplified administrative forms starting from FY 2026-27:
- Form 16 (Salary TDS Certificate) → Renamed to Form 130
- Form 16A (Non-Salary TDS Certificate) → Renamed to Form 131
- Form 12BB (Investment Declaration) → Renamed to Form 124
- Form 26AS (Annual Tax Statement) → Renamed to Form 168
11. Bigger HRA Benefit for Metro and Key Cities
Salaried employees renting in Bengaluru, Pune, Hyderabad, and Ahmedabad are now eligible for the higher 50% HRA exemption limit (previously restricted to Delhi, Mumbai, Chennai, and Kolkata). Additionally, taxpayers must disclose their relationship with the landlord to prevent incorrect or collusive HRA claims.
12. Transition to a Unified "Tax Year"
The new Act simplifies legal definitions by replacing the traditional two-term system of Financial Year (FY) and Assessment Year (AY) with a single, unified Tax Year. The tax year generally runs from April 1 to March 31. For new businesses or newly established income sources, the tax year initiates from the date of commencement or acquisition.
Old System vs. New Tax Year System
| Particulars | Old System (FY & AY) | New System (Tax Year) |
|---|---|---|
| Terminology | Separate Financial Year & Assessment Year | Single Tax Year |
| Income Period | 1 April – 31 March | 1 April – 31 March |
| Filing Reference | AY (following year) | Same Tax Year |
| Complexity | Often confusing for individual taxpayers | Simple and clear |
| New Businesses | Assessed in the subsequent AY | Tax Year begins on the date of commencement |
| New Income Source | Assessed in the subsequent AY | Tax Year starts when the income source starts |
Why This Change Matters
Many taxpayers found it confusing to deal with both FY and AY. The new Tax Year concept removes this complexity by using a single term, making tax rules easier to understand, especially for first-time taxpayers and small businesses.
Will It Affect Your Tax Filing?
No major changes. Your tax return filing process and due dates remain the same. The new system simply makes tax compliance more straightforward by replacing two different year concepts with one easy-to-understand Tax Year.
