What goes into the figure
- Section 87A rebate — a resident pays no tax up to ₹12 lakh under the new regime, or ₹5 lakh under the old. Non-residents don’t get this rebate.
- Surcharge — 10% / 15% / 25% / 37% as income crosses ₹50 lakh, ₹1 crore, ₹2 crore and ₹5 crore, with marginal relief at each step. Under the new regime the top surcharge is capped at 25%.
- Health & education cess — 4% on the tax (plus surcharge), added at the end.
- Standard deduction — ₹75,000 (new) or ₹50,000 (old) for salary and pension income, applied automatically.
