What the Law Says
Provisions Under Income Tax Act, 1961
ITR-1 Form of the Income Tax Act, 1961 governs ITR-1. The section establishes: (a) the scope of taxability, (b) computation methodology, (c) deductions and exemptions available, (d) compliance requirements, and (e) consequences of non-compliance. The Income Tax Rules, 1962 provide detailed procedural requirements including prescribed forms, methods of valuation, and timelines.
Changes Under Income Tax Act, 2025
1. Tax Year Concept: The Previous Year/Assessment Year system is being replaced with a unified "Tax Year" concept, simplifying compliance.
2. Simplified Language: The new Act uses clearer, more modern language with fewer cross-references and provisos.
3. Rationalized Provisions: Many overlapping sections have been merged, redundant provisions removed, and the overall structure streamlined from 298 sections to about 536 clauses organized in 23 chapters.
4. Default New Regime: The new tax regime (lower rates, fewer deductions) continues as the default under the new Act.
5. Transition: The new Act will apply from a date to be notified. Until then, the Income Tax Act, 1961 remains fully operative. All references in this article to specific sections are to the 1961 Act unless stated otherwise.

Detailed Explanation with Practical Examples
Example 1 (Salaried): Rahul works in an IT company in Faridabad earning Rs. 12 lakh per annum. Under the new tax regime (default from FY 2024-25), his tax computation is:
| Particular | Amount (Rs.) |
|---|---|
| Gross Salary | 12,00,000 |
| Less: Standard Deduction | (75,000) |
| Taxable Income | 11,25,000 |
| Tax (New Regime Slab FY 2025-26) | |
| 0-4,00,000: Nil | 0 |
| 4,00,001-8,00,000: 5% | 20,000 |
| 8,00,001-12,00,000: 10% | 32,500 |
| Total Tax | 52,500 |
| Less: Rebate u/s 87A (if income up to Rs. 12 lakh) | (52,500) |
| Tax Payable | NIL |
| Health & Education Cess 4% | 0 |
| Net Tax Payable | NIL |
Example 2 (Business): Priya runs a trading business with turnover of Rs. 1.5 crore (90% digital receipts). She can opt for presumptive taxation u/s 44AD and declare 6% of digital turnover as income = Rs. 9 lakh. Since this is below the basic exemption + deductions, her tax liability could be minimal.
Example 3 (Capital Gains Post-July 2024): An investor sells listed equity shares held for 18 months at a profit of Rs. 3 lakh. Post-Finance Act 2024 changes: LTCG on listed equity is taxed at 12.5% (reduced from earlier 10%) with exemption of Rs. 1.25 lakh. Tax = 12.5% of (3,00,000 - 1,25,000) = Rs. 21,875 + 4% cess = Rs. 22,750.
