How this is calculated
The steps, as the law sets them
- Taxable income = salary − the standard deduction (₹75,000 in the new regime, ₹50,000 in the old; s.19) + other income, rounded to the nearest ₹10 (s.516).
- Tax on the slabs: each slab’s rate on the part of the income inside it. New regime: s.202(1). Old regime: the Finance Act 2026 slabs for the taxpayer’s age.
- Rebate (s.156): the new regime takes off the whole tax, up to ₹60,000, while taxable income is at most ₹12,00,000. Just above that, marginal relief keeps the tax no higher than the income above ₹12,00,000. The old regime’s rebate is up to ₹12,500 at taxable income up to ₹5,00,000, with no relief above.
- Surcharge on the tax: 10% above ₹50 lakh, 15% above ₹1 crore and 25% above ₹2 crore in the new regime; 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore and 37% above ₹5 crore in the old. Marginal relief at each step (Finance Act 2026 s.3(5) for the new regime; First Schedule Part I-B Paragraph F for the old).
- Cess: 4% of the tax and surcharge (Finance Act 2026 s.3(15)).
- The total is rounded to the nearest ₹10 (s.516).
Assumptions
- A resident individual, for Tax Year 2026-27 (FY 2026-27): income earned from 1 April 2026 to 31 March 2027.
- Salary is the gross salary for the year, HRA included: the new regime allows no HRA exemption (s.202(2)(a)), and the old regime here takes none.
- Other income is added in full at the slab rates: enter its taxable amount.
- The old regime is shown with the standard deduction only: no other deductions or exemptions.
- Capital gains, other income taxed at special rates, and professional tax are not included.
Why can the official calculator show a different figure?
The Income Tax Department’s calculator has a Basic tab and an Advance tab. In our checks, the Basic tab (new regime) left out three rules of the Act: the rebate’s marginal relief just above ₹12 lakh, the surcharge’s marginal relief, and the rounding to ₹10. So just above those thresholds it shows more tax than the Act charges. The Advance tab matched our figures to the rupee, with three exceptions. Just above ₹2 crore of income it charged a 15% surcharge instead of 25% with marginal relief, in both regimes. Above ₹5 crore it charged the old regime 25% instead of 37%. And it does not round taxable income to ₹10: in the old regime, taxable income of ₹5,00,001 to ₹5,00,004 rounds down to ₹5,00,000 under the Act (s.516) and gets the full rebate, where the calculator shows tax. We follow the Act.
Which regime applies if I don’t choose?
The new regime (s.202) is the default. To be taxed under the old regime you opt out of it under s.202(4). The comparison under the calculator shows both.
Is a ₹12.75 lakh salary tax-free?
Yes, under the new regime, for a resident with no other income. The ₹75,000 standard deduction brings it to ₹12,00,000 of taxable income, and the s.156 rebate cancels the tax on up to ₹12,00,000. Above ₹12,00,000 of taxable income (after the rounding to ₹10) the full rebate ends, and its marginal relief keeps the tax, before cess, no higher than the income above ₹12,00,000.
