Key takeaways
- At this income the new regime computes ₹97,500.00 of tax and the old regime ₹2,57,400.00 — a difference of ₹1,59,900.00.
- A gross ₹15.00 L less ₹75,000.00 of standard deduction leaves ₹14.25 L taxable — an effective 6.5% across the whole income.
- The next ₹1,00,000 of income would add ₹15,600.00 of tax under the new regime — a marginal rate of 15.6%.
Tax under each regime
Both figures use the income and deductions entered above. Deductions only apply under the old regime.
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
How do the new and old tax regimes differ?
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. Which produces the lower tax depends entirely on the deductions you can actually claim. This calculator computes both from your own numbers so you can compare them side by side.
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 automatically when the income is salary or pension; business, professional and other income, F&O trading included, gets none.
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: 10% above ₹50 lakh of taxable income, 15% above ₹1 crore, 25% above ₹2 crore, and above ₹5 crore 37% in the old regime while the new regime stays at 25%. Just above each threshold marginal relief applies — tax plus surcharge cannot exceed the bill at the threshold by more than the income above it — and this calculator applies that relief. A 4% cess applies on top of tax plus surcharge.
