How it works
The maths, in plain English.
New regime (default), FY 2026-27. Nil up to ₹4 lakh; 5% to ₹8 lakh; 10% to ₹12 lakh; 15% to ₹16 lakh; 20% to ₹20 lakh; 25% to ₹24 lakh; 30% above. Standard deduction ₹75,000 for salaried people and pensioners. A rebate makes tax nil up to ₹12 lakh of taxable income, with marginal relief just above it.
Old regime. Nil up to ₹2.5 lakh (₹3 lakh from age 60, ₹5 lakh from 80); 5% to ₹5 lakh; 20% to ₹10 lakh; 30% above. Standard deduction ₹50,000, plus the deductions you enter. Rebate up to ₹12,500 when taxable income is ₹5 lakh or less.
Both. Surcharge of 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore (and 37% above ₹5 crore in the old regime only), with marginal relief; then 4% cess. Budget 2026 left all of this unchanged.
Not covered: special-rate income such as capital gains, which is taxed separately and is not eligible for the 87A rebate in the new regime; agricultural income; AMT. Ask us for an exact computation.
