About these calculators

These calculators follow the income tax rules for FY 2026-27 (AY 2027-28). The new regime is the default and charges no tax on a salary of up to ₹12.75 lakh. The old regime has higher rates but allows deductions such as HRA, 80C, 80D and home loan interest.

Every calculator shows the slab-by-slab working, so you can check the answer against your Form 16 or your employer’s TDS.

Frequently asked questions

Which tax regime should I choose?

For most salaried people the new regime costs less. The old regime wins only with large deductions: more than about ₹5.5 lakh apart from the standard deduction at a ₹15 lakh salary. See old vs new regime.

Is income up to ₹12 lakh tax-free?

In the new regime, yes: a rebate wipes out the tax on taxable income up to ₹12 lakh. With the ₹75,000 standard deduction, a salary up to ₹12.75 lakh pays no tax. See how the rebate works.

Did the Income-tax Act, 2025 change the tax rates?

No. The new Act took effect on 1 April 2026 and renumbered many sections, but kept the slabs, rebate and deduction limits.
