India operates a dual income tax regime system introduced in FY 2020-21, giving taxpayers the choice between the old regime (with deductions) and the new regime (lower slab rates, fewer deductions). The new regime is now the default for all taxpayers and features six slabs: 0% up to ₹3 lakh, 5% on ₹3–7 lakh, 10% on ₹7–10 lakh, 15% on ₹10–12 lakh, 20% on ₹12–15 lakh, and 30% above ₹15 lakh. A standard deduction of ₹75,000 was introduced for salaried individuals under the new regime in Budget 2024, reducing the effective tax burden.
Under the old regime, the most widely used deduction remains Section 80C, which allows up to ₹1.5 lakh per year across qualifying instruments including EPF, PPF, life insurance premiums, ELSS mutual funds, NSC, and housing loan principal. Additional deductions under Sections 80D (health insurance), 80E (education loan interest), and HRA exemption can make the old regime more advantageous for those with large deductible expenses.
Tax deduction at source (TDS) is the primary mechanism through which the government collects income tax from salaried employees: employers calculate estimated annual tax liability and deduct it equally across months. Self-employed individuals and those with additional income sources must pay advance tax in four quarterly installments when expected tax liability exceeds ₹10,000 in a financial year. Surcharges apply to incomes above ₹50 lakh, raising the effective top marginal rate beyond 30%.
The choice between old and new regime depends on the total value of deductions available to the individual. As a rough rule, if total deductions (80C + HRA + 80D + other) exceed approximately ₹3.75 lakh, the old regime is more beneficial for those in the 30% slab. For most middle-income earners with standard deductions only, the new regime yields lower tax. The rebate under Section 87A eliminates tax entirely for individuals with taxable income up to ₹7 lakh under the new regime.
