Why the new regime wins here. At ₹18,00,000, the old regime only catches up once your deductions cross roughly ₹6,42,000 — which usually needs a home loan on top of a full 80C and HRA.

This is one year, calculated once.

Frequently asked

Is the new regime the default for FY 2026–27?

Yes. The new regime has been the default since FY 2023–24 and applies unless you opt out. Salaried taxpayers can switch between regimes each year; those with business income can switch back only once.

What is the standard deduction under each regime?

₹75,000 under the new regime and ₹50,000 under the old one, available against salary and pension income. It does not apply to business or freelance income.

Do I pay any tax if I earn ₹12 lakh?

Under the new regime, no. The section 87A rebate covers the full liability up to ₹12 lakh of taxable income, and marginal relief softens the jump just above it. A salaried person with the ₹75,000 standard deduction effectively pays nothing up to ₹12.75 lakh of salary.

How much in deductions do I need before the old regime wins?

It depends on income. At ₹18 lakh you need roughly ₹8 lakh of deductions, which in practice means a full 80C, HRA and a home loan. The calculator shows your own break-even figure once you enter your income.

Does this include surcharge?

Yes. Surcharge starts above ₹50 lakh of total income and is applied automatically. The new regime caps surcharge at 25%, while the old regime goes up to 37% above ₹5 crore.
