How the calculator works

It applies the income-tax slabs from Budget 2025, which continue to apply for the current financial year. For each regime it:

  1. Subtracts the standard deduction (₹75,000 new, ₹50,000 old) and any deductions you enter.
  2. Applies the slab rates to your taxable income.
  3. Applies the Section 87A rebate, with marginal relief just above the limit.
  4. Adds surcharge for incomes above ₹50 lakh (capped at 25% in the new regime), with marginal relief.
  5. Adds the 4% health and education cess.

Frequently asked questions

Which tax regime is better for me?
For most salaried people the new regime is cheaper, especially if your deductions are below about ₹4–5 lakh a year. The old regime can win if you claim large deductions such as HRA, home-loan interest and full 80C and 80D. Enter your numbers above to see the exact difference.
Is income up to ₹12 lakh tax-free?
Under the new regime, yes. A rebate under Section 87A cancels tax on taxable income up to ₹12 lakh. Salaried people also get a ₹75,000 standard deduction, so a salary of up to ₹12.75 lakh pays no tax. Income taxed at special rates, such as capital gains, does not get this rebate.
What are the new regime tax slabs?
Up to ₹4 lakh: nil; ₹4–8 lakh: 5%; ₹8–12 lakh: 10%; ₹12–16 lakh: 15%; ₹16–20 lakh: 20%; ₹20–24 lakh: 25%; above ₹24 lakh: 30%. A 4% health and education cess is added to the tax.
What is marginal relief?
If your income is only slightly above ₹12 lakh, marginal relief ensures the extra tax is never more than the extra income. The same principle applies when income crosses a surcharge threshold such as ₹50 lakh. The calculator applies both automatically.
Which deductions are allowed in the new regime?
Only a few: the standard deduction of ₹75,000, the employer’s NPS contribution under Section 80CCD(2) and a handful of others. Popular deductions like 80C, 80D, HRA and home-loan interest on a self-occupied house are available only in the old regime.
