Calculate income tax on ₹1 crore salary for Tax Year 2026-27 under the default and optional old regime, including surcharge, marginal relief and cess.
For salary-only gross income of ₹1 crore, the estimated default-regime tax is ₹29,25,780, compared with ₹32,00,340 under the represented optional-old-regime inputs.
The calculation applies the relevant salary standard deduction, slab tax, individual surcharge with marginal-relief logic and 4% health and education cess.
Worked-example age assumption: the static optional-old-regime result uses the regular below-60 slab table. If you are 60–79 or 80+, choose the matching age category in the interactive calculator below.
Keep surcharge, marginal relief and any special-rate income separate from ordinary salary before acting on the estimate. The interactive calculator exposes the inputs that can change this boundary result.
