About the income tax calculator

This calculator estimates your income tax for the financial year under both the old and new regimes, then tells you which one leaves more money in your pocket. It applies the latest slab rates, the standard deduction, the Section 87A rebate, surcharge, and the 4% health and education cess so the figure you see reflects what you would actually pay.

It is built for salaried professionals and anyone weighing the two regimes. The old regime rewards deductions like Section 80C, 80D, home loan interest, and HRA, while the new regime offers lower slab rates and a higher standard deduction but almost no deductions. The right choice depends on how much you claim.

Treat the result as a close estimate for planning. Your actual liability can differ once perquisites, capital gains, other heads of income, and employer reporting are accounted for. For filing, confirm the numbers with the income tax portal or a qualified advisor.

How do I use the income tax calculator?

  1. Enter your gross annual income: Add your total income before any deductions, including salary, bonus, and other taxable receipts.
  2. Select your age group: Choose below 60, 60 to 80, or above 80. Age affects the basic exemption limit under the old regime.
  3. Add your deductions: Enter Section 80C investments, 80D health premiums, home loan interest under Section 24b, HRA exemption, and any other eligible deductions. These apply to the old regime.
  4. Compare the two regimes: The calculator shows tax under both regimes side by side, with a full slab by slab breakdown for each.
  5. Review the recommendation: See which regime costs less, how much you save, and your effective tax rate. Use Share to save or send the comparison.

How is income tax calculated?

Total tax = (sum of income taxed in each slab) + surcharge + 4% cess, minus the Section 87A rebate

The new regime uses a single set of slabs with a higher standard deduction of ₹75,000 and a rebate up to ₹12,00,000 of taxable income. The old regime uses age based slabs, a ₹50,000 standard deduction, and lets you claim deductions such as 80C, 80D, 24b, and HRA.
