Why use Income Tax Calculator India?

Since the new regime became the default, the annual question for every Indian salaried taxpayer is the same: declare the new regime, or gather deductions and stay on the old one? This calculator answers it with FY 2026-27 (AY 2027-28) figures — the slabs Budget 2026 carried forward from Budget 2025. It applies each regime's standard deduction automatically, layers in the Section 87A rebate (with the marginal relief that prevents a tax cliff just above ₹12 lakh taxable), adds surcharge where income is high enough, and finishes with the 4% cess, then puts the two results side by side with the cheaper one highlighted. The deciding variable is your old-regime deduction total. As a rule of thumb at mid salaries, the old regime needs roughly ₹4–4.5 lakh of combined deductions before it catches the new regime, which few taxpayers reach without home-loan interest — but the crossover moves with income, which is why entering your real numbers beats any rule of thumb. Results are estimates for salary income; capital gains, business income, and less common deductions are out of scope, so verify with the income tax portal or a CA before filing.

Frequently asked questions

What are the new regime tax slabs for FY 2026-27?

Income up to ₹4 lakh is nil; ₹4–8 lakh at 5%; ₹8–12 lakh at 10%; ₹12–16 lakh at 15%; ₹16–20 lakh at 20%; ₹20–24 lakh at 25%; and above ₹24 lakh at 30%. Budget 2026 kept the Budget 2025 slabs unchanged. A 4% health and education cess applies on the tax.

Is income up to ₹12 lakh really tax-free?

Under the new regime, yes — the Section 87A rebate (up to ₹60,000) wipes out the tax on taxable income up to ₹12 lakh. For a salaried person the ₹75,000 standard deduction pushes that to ₹12.75 lakh of gross salary. Just above the limit, marginal relief caps the tax at the income above ₹12 lakh, so there's no cliff.

Which regime is better for me?

It depends entirely on your deductions. With few deductions the new regime's lower slab rates usually win; with heavy deductions (full 80C, 80D, big HRA exemption, home-loan interest) the old regime can still come out ahead at higher salaries. Enter your actual numbers — the comparison is the whole point of this tool.

Does this include surcharge?

Yes — 10% above ₹50 lakh, 15% above ₹1 crore, and 25% above ₹2 crore taxable income (the new regime caps surcharge at 25%; the old regime's 37% top surcharge applies above ₹5 crore). Marginal relief near surcharge thresholds is not modeled, so results right at those edges may differ slightly.

Is this the same as my employer's TDS?

Your employer deducts TDS monthly based on the regime you declare and their projection of your annual income. This calculator shows the annual liability that TDS is aiming at; differences reconcile when you file your return.
