What is the Income Tax Calculator: New vs Old Regime? This calculator computes your tax under both the new and old regimes for FY 2026-27 and tells you which one is cheaper, using slabs, the standard deduction, the 87A rebate and 4% cess.
How to use the Income Tax Calculator: New vs Old Regime
- Enter your annual gross salary and age group.
- Add the deductions you actually claim under the old regime: 80C-type investments, health insurance, NPS, HRA exemption and home loan interest.
- Read which regime costs less and the yearly saving.
- Share the result or change the numbers to see how much extra deduction would make the old regime win.
Frequently asked questions
Which tax regime is better for me?
For most salaried people below about ₹12.75 lakh the new regime is tax-free. The old regime tends to win only with very large deductions, often HRA plus home loan interest plus 80C. This calculator compares both on your numbers.
Are deductions allowed in the new regime?
Only the standard deduction of ₹75,000 for salaried taxpayers, plus a few items such as employer NPS contribution. Most old-regime deductions such as 80C and HRA are not available.
Does this include surcharge?
No. It is built for incomes up to ₹50 lakh. Above that, surcharge applies and you should use a full tax computation or ask a chartered accountant.
