Old vs New Tax Regime: Which One Saves You More Money in 2026?

Choosing between the Old Tax Regime and the New Tax Regime is a decision every Indian taxpayer makes each year. The New Regime has become much harder to argue against: it carries a Standard Deduction of ₹75,000 and a Section 87A rebate that wipes out tax entirely on taxable income up to ₹12,00,000, which works out to a tax-free salary of ₹12.75 Lakhs. The Old Regime now only wins if your deductions are unusually large, and this guide shows exactly where that line falls.
