Income Tax Calculator
About the Income Tax Calculator
This calculator estimates your income tax in India under both the new and old regimes for the current financial year, so you can compare them side by side. It applies the slab rates, the standard deduction, the Section 87A rebate, surcharge for higher incomes and the 4% health-and-education cess.
Enter your income (and, for the old regime, deductions such as 80C and HRA) to see the tax under each option. It is an estimate to guide planning — your final liability depends on your full return.
Frequently asked questions
Should I choose the new or old tax regime?
The new regime has lower slab rates but removes most deductions; the old regime has higher rates but lets you claim 80C, HRA, home-loan interest and more. If you have large deductions the old regime can win; if not, the new one usually does. This calculator shows both so you can compare your own numbers.
What is the Section 87A rebate?
It is a rebate that makes your tax nil up to a certain income. Under the new regime, as of 2026, there is effectively no tax up to ₹12 lakh of taxable income (about ₹12.75 lakh of salary after the standard deduction), with marginal relief just above that level.
What is the standard deduction?
It is a flat deduction from salary income that needs no proof — ₹75,000 under the new regime and ₹50,000 under the old regime as of 2026. The calculator applies it to salary automatically.
Is the figure from this calculator my final tax?
Treat it as a close estimate. It applies the standard slabs, rebate, surcharge and cess, but your actual return may include items it does not model — capital gains, other income heads or specific exemptions — so confirm with your final computation.
How is surcharge applied?
A surcharge is an extra percentage on the tax (not the income) for higher incomes, starting at ₹50 lakh and rising in steps. The new regime caps the top surcharge at 25%, while the old regime goes up to 37%. A 4% cess applies on top of tax plus surcharge.
