For Tax Year 2026-27, the new regime charges no tax on taxable income up to ₹12 lakh, thanks to a rebate of up to ₹60,000. With the ₹75,000 standard deduction, a salary of up to ₹12.75 lakh pays ₹0 tax. Above that, slab rates of 5% to 30% apply, plus 4% cess.

## How it is calculated

```
Tax = slab tax − rebate + surcharge, then + 4% health and education cess
```

- Taxable income = salary − standard deduction (₹75,000 new, ₹50,000 old) + other income − deductions.
- Deductions such as 80C, 80D, HRA and home loan interest count only in the old regime. Employer NPS contribution counts in both.
- Rebate: no tax if taxable income is at most ₹12 lakh (new) or ₹5 lakh (old). Just above ₹12 lakh, marginal relief caps tax at the income above ₹12 lakh.
- Surcharge: 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore, and 37% above ₹5 crore in the old regime only, with marginal relief at each step.

## Worked example

- Inputs: ₹18,00,000 salary, ₹4,00,000 of old-regime deductions, age below 60
- Result: New regime ₹1,50,800, old regime ₹2,26,200. The new regime is cheaper by ₹75,400
