Income Tax Filing in India — The Complete Picture for FY 2025-26
Income Tax Return (ITR) filing is the annual declaration of your total income, deductions, and tax liability to the Income Tax Department of India. It is mandatory for individuals and entities above the basic exemption limit, and for all companies and LLPs regardless of income.
Filing ITR accurately and on time does far more than avoid penalties — it enables carry-forward of losses, claims for refunds, loan and visa applications, and investor due diligence. Filing it late or incorrectly attracts interest, penalty, and increasingly, automated scrutiny from AIS-driven analytics.
Two major legislative events have transformed income tax compliance for FY 2025-26 and beyond: Finance Act 2025 (effective 1 April 2025) overhauled the new tax regime slabs and rebates, and the Income Tax Act 2025 (effective 1 April 2026) structurally replaced the Income Tax Act 1961. StartupDost keeps every return and advisory completely current with both.
Finance Act 2025 — The Most Important Income Tax Changes for FY 2025-26
1. Revised New Tax Regime Slabs — Section 115BAC
The Finance Act 2025 substantially revised the new tax regime slabs. The new regime is the default regime since FY 2023-24. Updated slabs effective FY 2025-26 (AY 2026-27):
| Annual Taxable Income | Tax Rate — New Regime (Section 115BAC) |
|---|---|
| Up to Rs.4,00,000 | NIL |
| Rs.4,00,001 to Rs.8,00,000 | 5% |
| Rs.8,00,001 to Rs.12,00,000 | 10% |
| Rs.12,00,001 to Rs.16,00,000 | 15% |
| Rs.16,00,001 to Rs.20,00,000 | 20% |
| Rs.20,00,001 to Rs.24,00,000 | 25% (NEW slab in Finance Act 2025) |
| Above Rs.24,00,000 | 30% |
⚠ Plus Health and Education Cess at 4% and applicable surcharge. The 25% slab between Rs.20L and Rs.24L is a new addition — reducing effective marginal rate for this bracket from 30% to 25%.
2. Section 87A Rebate Enhanced to Rs.60,000
The rebate under Section 87A has been increased to Rs.60,000 under the new tax regime (from Rs.25,000). This means individuals with taxable income up to Rs.12 lakh under the new regime pay zero income tax — their gross tax liability is fully offset by the rebate. Note: The rebate is not available against tax on special-rate income like capital gains under Section 111A or 112A.
For salaried employees, the additional standard deduction of Rs.75,000 under the new regime makes income up to Rs.12,75,000 effectively zero-tax in FY 2025-26.
3. Old Tax Regime — Unchanged in FY 2025-26
| Annual Taxable Income | Tax Rate — Old Regime |
|---|---|
| Up to Rs.2,50,000 (Rs.3L for seniors / Rs.5L for super-seniors) | NIL |
| Rs.2,50,001 to Rs.5,00,000 | 5% |
| Rs.5,00,001 to Rs.10,00,000 | 20% |
| Above Rs.10,00,000 | 30% |
⚠ Old regime: Section 87A rebate of Rs.12,500 (zero tax up to Rs.5L). Standard deduction Rs.50,000 for salaried. All deductions — 80C, 80D, HRA, home loan interest — remain available.
4. Capital Gains Tax — Major Changes Effective July 23, 2024
The Finance (No. 2) Act 2024 made the most sweeping capital gains changes since 2018 — effective from 23 July 2024, continuing into FY 2025-26:
| Asset Type | Holding for LTCG | LTCG Tax Rate | STCG Tax Rate |
|---|---|---|---|
| Listed Equity / Equity MF (STT paid) | > 12 months | 12.5% above Rs.1.25L exemption | 20% (Section 111A) |
| Property (acquired on/after 23 Jul 2024) | > 24 months | 12.5% — no indexation | Slab rates |
| Property (acquired before 23 Jul 2024) | > 24 months | 12.5% OR 20% with indexation (taxpayer's choice) | Slab rates |
| Gold / Debt MF / Other non-equity assets | > 24 months | 12.5% — no indexation | Slab rates |
| Unlisted Shares | > 24 months | 12.5% | Slab rates |
⚠ CII for FY 2025-26: 376 (CBDT Notification No. 70/2025). Grandfathering continues for listed equity held before 31 January 2018 — higher of actual cost or FMV as of 31 Jan 2018 is deemed cost of acquisition.
5. Income Tax Act 2025 — Structural Overhaul from 1 April 2026
The Income Tax Act 2025 replaces the Income Tax Act 1961 (in force since 1961 — over 60 years). It is effective from 1 April 2026. Key structural changes relevant to taxpayers:
- 'Tax Year' replaces 'Financial Year' + 'Assessment Year' — ITR for April 2026 to March 2027 is Tax Year 2026-27
- Section 392: TDS on salary (replaces old Section 192)
- Section 393: All other TDS payments consolidated (replaces entire 194-series)
- Section 394: All TCS provisions (replaces scattered 206C provisions)
- Form 130: Replaces Form 16 (TDS certificate for salary)
- Form 121: Replaces Forms 15G and 15H (self-declaration for nil/lower TDS)
- Payment codes 1001-1092 replace old section codes on challans and returns
- Tax rates, slab rates, and deduction limits are unchanged for Tax Year 2026-27
⚠ For FY 2025-26 (AY 2026-27), the Income Tax Act 1961 still governs. From 1 April 2026 (Tax Year 2026-27 onwards), the Income Tax Act 2025 applies. StartupDost's systems are fully updated for both.
