Old vs new tax regime: calculator and comparison

ClearTax Free Beginner India

A calculator that works out your tax under both regimes from your salary and deductions, with the slabs and the deductions each regime allows.

  • The new regime's rebate makes income up to ₹12 lakh tax free, and its standard deduction is ₹75,000 against ₹50,000 in the old.
  • The new regime drops 80C, 80D, HRA and interest on a self-occupied home loan; employer NPS contributions count in both.
  • The old regime wins only when deductions cross a break-even that rises with income.
