What it does
Type your yearly salary and any deductions you claim, and the calculator works out your income tax for FY 2026-27 under both regimes at once. Each column shows the taxable income, the tax on the slabs, the Section 87A rebate, any surcharge, the 4% cess and the money left after tax. The cheaper regime is marked in green, with how much it saves you a year and a month. Everything is worked out in your browser.
Once you know your tax, plan where the rest goes with the budget planner, or compare with the Canada and UK tax calculators.
How to use it
- Pick your age: the old regime gives seniors a higher tax-free amount.
- Type your gross salary for the year, and any other income such as bank interest or rent.
- Open Old regime deductions and type what you claim. The new regime ignores them, apart from its own Rs 75,000 standard deduction.
What each part means
- New regime: the default. Slabs of 0% up to Rs 4 lakh, then 5%, 10%, 15%, 20% and 25% in Rs 4 lakh steps, and 30% above Rs 24 lakh.
- 87A rebate: no tax if taxable income is up to Rs 12 lakh (new) or Rs 5 lakh (old). Just above Rs 12 lakh, marginal relief keeps the tax no higher than the income above Rs 12 lakh.
- Surcharge: 10% above Rs 50 lakh, 15% above Rs 1 crore, 25% above Rs 2 crore (old regime: 37% above Rs 5 crore), with marginal relief.
- Cess: 4% on tax plus surcharge.
- Marginal rate: the tax on your next Rs 1,000.
Worked example
Asha earns Rs 15,00,000 and claims Rs 1,50,000 under 80C and Rs 25,000 under 80D. New regime: taxable Rs 14,25,000, tax Rs 93,750 plus Rs 3,750 cess = Rs 97,500. Old regime: taxable Rs 12,75,000, tax Rs 1,95,000 plus cess = Rs 2,02,800. The new regime saves her Rs 1,05,300.
A salary of Rs 12,75,000 pays no tax in the new regime: Rs 75,000 standard deduction leaves Rs 12 lakh, fully covered by the rebate.
FAQs
Which regime should I choose? The one with less tax. The old regime only wins with large deductions, such as a big home loan and full 80C and 80D.
Does the new Income-tax Act change my tax? Not the slabs for 2026-27. Section numbers change, so your Form 16 may use new ones.
Is anything saved? No. Nothing you type leaves the page. Not financial or tax advice; check the official source.
