India’s taxation framework has entered a new era with the introduction of the Income Tax Act, 2025. Replacing the decades-old Income Tax Act, 1961, the new legislation aims to simplify tax compliance, modernize terminology, and consolidate scattered provisions into a more structured framework.
One of the biggest changes is the replacement of the concepts of “Previous Year” and “Assessment Year” with a single unified term — Tax Year. Along with this, several section numbers governing exemptions, deductions, rebates, and tax computations have been renumbered and reorganized.
If you are filing your income tax return under the new regime, understanding these revised provisions is essential.
The new Act compresses and reorganizes the earlier law into a streamlined structure consisting of 536 sections. While many tax principles remain conceptually similar, the reference sections have substantially changed.
Some of the most important revisions include:
| Particulars | Old Income Tax Act, 1961 | New Income Tax Act, 2025 | Key Impact |
|---|---|---|---|
| New Tax Regime | Section 115BAC | Section 202 | Becomes the official default tax regime |
| Tax Rebate | Section 87A | Section 156 | 100% rebate for eligible taxpayers up to ₹12 lakh taxable income |
| Standard Deduction | Section 16(ia) | Section 19 | Fixed deduction of ₹75,000 from salary income |
| Exempt Income | Section 10 | Section 11 | Main umbrella provision for exempt incomes |
| House Property Deductions | Section 24 | Section 22 | Covers 30% standard deduction and interest deductions |
| Other Sources Income | Section 56 | Section 92 | Governs gifts, family pension, interest income, etc. |
| 80C Deductions | Section 80C | Section 123 | Restricted under default tax regime |
| NPS Employer Contribution | Section 80CCD(2) | Section 124 | Allowed up to 14% of salary under default regime |
| Medical Insurance Deduction | Section 80D | Section 126 | Not available under default regime |
| TDS Provisions | Sections 192–194T | Section 393 | Consolidated TDS framework |
| Filing of Return | Section 139 | Section 263 | Governs filing procedures and deadlines |
Under the old law, exempt incomes were primarily grouped under Section 10. The new legislation relocates these provisions to Section 11 and related schedules.
Agricultural income continues to remain fully exempt from direct taxation under the new law, subject to prescribed conditions.
This includes:
Although exempt, agricultural income may still be considered for rate purposes in certain situations.
Several retirement-related receipts remain exempt, including:
The exemptions are now routed through specialized schedules attached to Section 11.
Scholarships granted to meet educational expenses continue to enjoy exemption under the new framework.
Specific allowances and portions of family pension retain concessional or exempt treatment, depending on eligibility conditions.
The taxation of salary income continues under Sections 15 and 16 of the new Act.
A major relief available under the default tax regime is the standard deduction of ₹75,000 under Section 19.
This deduction is:
One of the most taxpayer-friendly changes is the rebate mechanism under Section 156.
Eligible resident individuals can claim a 100% tax rebate if their net taxable income does not exceed ₹12,00,000 under the prescribed conditions.
This effectively means:
The Income Tax Act, 2025 continues the philosophy of a simplified default tax regime with limited deductions.
Deduction for employer contribution to the National Pension System remains available up to:
This continues to be one of the key deductions preserved in the default regime.
Several traditional deductions are not available unless the taxpayer opts out of the default regime.
These include:
| Deduction | Old Section | New Section | Availability Under Default Regime |
|---|---|---|---|
| LIC, PPF, ELSS, Tuition Fees | 80C | 123 | Not Available |
| Medical Insurance Premium | 80D | 126 | Not Available |
| Housing Loan Principal | 80C | 123 | Not Available |
| Tax Saver FD | 80C | 123 | Not Available |
Taxpayers opting for the old-style deduction structure may need to formally opt out of the default regime, subject to eligibility rules.
A major administrative reform under the new Act is the consolidation of over 60 TDS provisions into a single comprehensive section — Section 393.
This restructuring aims to:
Businesses, deductors, and professionals may find compliance easier due to the unified coding structure.
The filing of income tax returns is now governed by Section 263.
This section covers:
Taxpayers should familiarize themselves with the revised section references to avoid compliance errors.
Under the new Income Tax Act, 2025, the following sections become especially important for regular taxpayers:
| Purpose | New Section |
|---|---|
| Tax Slabs & Default Regime | Section 202 |
| Standard Deduction | Section 19 |
| Tax Rebate | Section 156 |
| Exempt Income | Section 11 |
| NPS Deduction | Section 124 |
| Return Filing | Section 263 |
| TDS Provisions | Section 393 |
The Income Tax Act, 2025 represents one of the most significant structural reforms in India’s direct tax system in recent decades. While many taxation concepts remain familiar, the renumbering and consolidation of provisions require taxpayers, professionals, and businesses to adapt quickly.
For salaried individuals, the most critical provisions to understand are:
As the new framework becomes operational, taxpayers should carefully review how exemptions and deductions apply under the default regime before filing their returns.
