Income tax calculators

Estimate tax under the FY 2025-26 rules, including rebate and marginal relief. · 5 free calculators · Updated 6 August 2026

The new regime under Section 115BAC changed the arithmetic most salaried taxpayers grew up with. A resident individual with taxable income up to ₹12,00,000 pays nothing after the Section 87A rebate, and just above that threshold marginal relief caps the tax at the amount by which income exceeds ₹12,00,000. Our calculators implement both, plus surcharge with its own marginal relief and the 4% health and education cess.

Old regime still suits taxpayers with large deductions — home loan interest, HRA, 80C and 80D together can outweigh the lower new-regime rates. Run both calculators with the same gross salary before choosing, and treat every result as an estimate to verify with a tax professional or the Income Tax Department's own utility.
