FY 2025-26 · AY 2026-27

Income tax calculator

Both regimes, side by side, with the standard deduction, the section 87A rebate, surcharge, marginal relief and cess all applied. Nothing is sent anywhere — the arithmetic happens on your own device.

Deductions you claim

These count under the old regime only. The new regime allows almost none of them, which is the whole trade-off.

How that number is built

What separates the two regimes

The new regime has wider slabs and a larger standard deduction (₹75,000 against ₹50,000), but almost no other deductions. The old regime taxes more of your income at higher rates and then lets you subtract 80C, 80D, NPS and home loan interest from it.

Which wins is decided by how much you actually claim. A salaried person claiming nothing beyond the standard deduction is nearly always better off under the new regime. Someone with a full 80C, a health policy and a home loan can still be better off under the old one.

The 87A rebate, and the cliff after it

Under the new regime, taxable income up to ₹12,00,000 attracts a rebate of up to ₹60,000 — which for most people means no tax at all. A rupee over that limit would, without relief, cost far more than a rupee in tax, so marginal relief caps the tax at the amount by which you crossed the line. This calculator applies it; many do not, which is why their answer jumps at ₹12,00,000.

Slabs used, FY 2025-26
