Tax slabs for FY 2026-27 (assessment year 2027-28)

New regime (default): up to ₹4,00,000 nil; ₹4–8 lakh 5%; ₹8–12 lakh 10%; ₹12–16 lakh 15%; ₹16–20 lakh 20%; ₹20–24 lakh 25%; above ₹24 lakh 30%. Salaried taxpayers get a standard deduction of ₹75,000, and the section 87A rebate makes tax nil when taxable income is up to ₹12 lakh (about ₹12.75 lakh of salary).

Old regime: up to ₹2,50,000 nil (₹3 lakh for ages 60–79, ₹5 lakh for 80+); ₹2.5–5 lakh 5%; ₹5–10 lakh 20%; above ₹10 lakh 30%. Standard deduction is ₹50,000 and the rebate is up to ₹12,500 if taxable income is ₹5 lakh or less. Deductions such as 80C, 80D, home-loan interest and NPS apply.

Health and education cess of 4% is added on the tax. Surcharge applies on very high incomes (10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore, and 37% above ₹5 crore in the old regime; the new regime is capped at 25%), with marginal relief.

Which regime should you choose?

The new regime has lower rates but few deductions; the old regime has higher rates but lets you subtract 80C, 80D, home-loan interest and other items. Enter your deductions above and the calculator shows the cheaper option. As a rough guide, the old regime tends to win only when total deductions are large.
