What is Income Tax?

Income tax is a direct tax collected by the Government of India on income earned by individuals, businesses, and other entities during a financial year. It funds essential public services — roads, schools, hospitals, and defence.

The Income-tax Act, 2025 is India's brand-new tax law, passed by Parliament on 21 August 2025 and set to replace the decades-old Income-tax Act, 1961, from 1 April 2026. Its core aim: simplify, digitize, and reduce disputes.

Why Was the Income Tax Act 2025 Introduced?

The old 1961 Act had accumulated over 800 sections and 4,000+ amendments over 60 years — making it complex, litigation-heavy, and outdated for a digital economy. The new Act fixes this by:

✓     Compressing 800+ sections to just 536, across 23 chapters

✓     Replacing the confusing 'Assessment Year / Previous Year' distinction with a single unified Tax Year

✓     Moving to a digital first, faceless system — fewer office visits, more online processing

✓     Simplifying plain language so taxpayers can understand their obligations directly

Who Must File an Income Tax Return?

You are required to file an ITR if your income exceeds the basic exemption limit. Under the new regime (default from FY 2025-26), the exemption limit is ₹4 lakh. You should file even if tax payable is nil, in these cases:

✓     Salaried employees, freelancers, and self-employed professionals

✓     Individuals with bank deposits, rental income, or capital gains

✓     Anyone who has paid TDS and wants a refund

✓     NRIs earning income in India

Note: Under the New Regime, income up to ₹12 lakh is effectively tax-free due to the Section 87A rebate of up to ₹60,000.

New Tax Regime Slabs — Clause 202 (IT Act, 2025)

The New Tax Regime is now the default regime under the Income-tax Act, 2025. The revised slabs, effective FY 2025-26, are:

Standard Deduction: ₹75,000 available for salaried individuals under the New Regime.

Old Regime: Still available (optional). Retains higher slab rates but allows deductions under Section 80C, HRA, home loan interest, etc.

5 Key Changes Every First-Time Filer Should Know

✓     Tax Year Concept: 'Previous Year' and 'Assessment Year' merged into a single Tax Year — far less confusing for new filers

✓     Higher Rebate: Section 87A rebate raised to ₹60,000 under the New Regime — zero tax for income up to ₹12 lakh

✓     Updated Return Window: You can now file a corrected/updated return up to 48 months (4 years) after the end of the relevant Tax year — extended from the earlier 12 months

✓     Consolidated TDS: All TDS sections are merged into a single table (Section 393) for easy reference

✓     Digital Assets Recognized: Cryptocurrencies and Virtual Digital Assets (VDAs) are explicitly covered under Clauses 67, 196, 197, and 198 — taxed as capital gains

✓     31 March 2030 — Extended deadline to file an updated return (4-year window)

Late Filing Penalty (Section 234F): ₹1,000 if income ≤ ₹5 lakh; ₹5,000 for others.

New Regime or Old Regime — Which Should You Choose?

Choose the New Regime if:

✓     You do not have significant investments or deductions to claim

✓     Your income is up to ₹12 lakh (effectively tax-free after rebate)

✓     You prefer simplicity and fewer documents

Choose the Old Regime if:

✓     You have substantial 80C investments (PPF, ELSS, LIC), HRA, or home loan interest deductions exceeding ₹3.75 lakh in total
