Common questions

Is income up to ₹12 lakh tax-free in F.Y. 2026-27?

Under the new regime, yes for most resident individuals — the Section 87A rebate (₹60,000) makes taxable income up to ₹12 lakh tax-free, with marginal relief just above; salaried persons effectively reach ₹12.75 lakh with the standard deduction. In the new regime the rebate does not apply against special-rate capital gains; under the old regime the ₹12,500 rebate can absorb tax including STCG u/s 111A (only 112A gains are barred). This calculator applies both rules automatically.

Which is better, old or new tax regime?

It depends on one number: your total deductions. Below a break-even level of deductions the new regime wins; above it the old regime can win. This calculator computes both regimes on your figures and shows the exact break-even deduction amount.

Did income tax slabs change for F.Y. 2026-27?

No — the Finance Act, 2026 kept slabs, surcharge and the rebate unchanged. What changed is the law itself: the Income-tax Act, 2025 applies from 1 April 2026 with new section numbers, which this calculator displays alongside the familiar old ones.
