About this calculator
This free income tax calculator estimates your tax for FY 2025-26 (AY 2026-27) and shows the old and new regimes side by side so you can see which one costs you less. It applies the standard deduction, the section 87A rebate and the 4% health and education cess.
New regime vs old regime
The new regime has lower slab rates and a ₹75,000 standard deduction, but you give up most exemptions. The old regime keeps higher rates but lets you reduce taxable income with deductions like 80C (up to ₹1.5 lakh), 80D, HRA and home-loan interest. Enter your total old- regime deductions to compare fairly.
Worked example
On a ₹12,00,000 salary with ₹1,50,000 of deductions: the new regime works out to ₹0 (taxable income up to ₹12 lakh is fully rebated), while the old regime is about ₹1,17,000 — so the new regime wins here.
