How the comparison is worked out
Under the new regime (section 202), tax-year 2026-27 slabs are: nil up to ₹4 lakh, 5% to ₹8 lakh, 10% to ₹12 lakh, 15% to ₹16 lakh, 20% to ₹20 lakh, 25% to ₹24 lakh and 30% above. Salaried taxpayers get a ₹75,000 standard deduction, and the section 156 rebate makes taxable income up to ₹12 lakh tax-free.
The old regime keeps slabs of nil up to ₹2.5 lakh (₹3 lakh at 60, ₹5 lakh at 80), 5% to ₹5 lakh, 20% to ₹10 lakh and 30% above, with a ₹50,000 standard deduction and deductions such as section 123 (old 80C), section 126 (old 80D), HRA and home loan interest. A 4% cess applies under both.
Worked example
| Salary ₹15 lakh, ₹1.5 lakh under section 123 | New | Old |
|---|---|---|
| Taxable income | ₹14,25,000 | ₹13,00,000 |
| Tax including cess | ₹97,500 | ₹2,10,600 |
| Lower | New, by ₹1,13,100 |
Common questions
Which regime is the default for tax year 2026-27?
The new regime under section 202 is the default. Salaried taxpayers can choose the old regime when filing their return; those with business income have limited chances to switch.
Up to what income is tax zero under the new regime?
With the section 156 rebate (old 87A), taxable income up to ₹12 lakh pays no tax. For salaried people, the ₹75,000 standard deduction takes this to ₹12.75 lakh of salary.
Which deductions are lost in the new regime?
Most of them: section 123 (old 80C), section 126 (old 80D), HRA exemption, home loan interest on a self-occupied house and your own NPS contribution. Employer NPS contribution under section 124 and the standard deduction remain.
What does this calculator leave out?
It assumes you are resident in India; non-residents do not get the section 156 rebate. It also leaves out capital gains at special rates, losses carried forward, agricultural income and a few rarer deductions. For a full plan built on your complete situation, use BI CFO's tax plan.
