The biggest question every salaried Indian faces in 2025-26: New Regime or Old Regime? Budget 2025 made the New Regime more attractive with a higher 87A rebate (zero tax up to ₹12L) and higher standard deduction (₹75,000). But Old Regime is still better for many people with high deductions.

Quick answer for most people: If your income is up to ₹12 lakh — choose New Regime (zero tax). If income is above ₹15L and you have deductions above ₹4.25L — Old Regime may save more. Use our calculator to compare your exact numbers.
