This old vs new tax regime calculator works out your income tax both ways, side by side, for FY 2026-27 (the first "tax year" under the Income-tax Act, 2025). The slab rates are the same as FY 2025-26, so it also works for the return you file for last year. It shows which regime costs less, by how much, and how many deductions you would need before the old regime wins.
Step 1
About you
Age only changes the old regime's tax-free limit. The new regime has one set of slabs for everyone.
Salaried people and pensioners get a standard deduction: ₹75,000 in the new regime, ₹50,000 in the old.
Step 2
Your income for the year
Annual figure, including bonus and taxable allowances. Enter the full HRA you receive here; the exempt part goes in Step 3.
FD and savings interest, rent received after the 30% standard deduction, freelance or business profit. Leave out capital gains on shares and mutual funds: they are taxed at their own rates in both regimes.
Deductible in both regimes: up to 14% of basic + DA in the new regime, 10% in the old.
Step 3
Deductions you can claim (old regime only)
Enter what you actually spend or invest. The calculator applies each limit for you. Section names are the familiar 1961-Act ones.
The exempt part only (least of three limits). Your employer's payslip or Form 16 usually shows it.
Capped at ₹1,50,000. Now section 123 of the new Act.
₹25,000 for your family (₹50,000 if you are a senior), plus up to ₹50,000 for senior-citizen parents. Now section 126.
Capped at ₹2,00,000 a year.
Capped at ₹50,000, over and above the ₹1.5 lakh.
Savings interest up to ₹10,000; for seniors, bank and post office interest up to ₹50,000.
Capped at ₹2,500.
Enter only the deductible amount.

How this calculator works
It applies the rates that hold for FY 2026-27. The Budget in February 2026 left slabs, rebate, surcharge and cess unchanged, so the same figures applied in FY 2025-26.
| New regime (all ages) | Rate | Old regime (below 60) | Rate |
|---|---|---|---|
| Up to ₹4 lakh | Nil | Up to ₹2.5 lakh | Nil |
| ₹4–8 lakh | 5% | ₹2.5–5 lakh | 5% |
| ₹8–12 lakh | 10% | ₹5–10 lakh | 20% |
| ₹12–16 lakh | 15% | Above ₹10 lakh | 30% |
| ₹16–20 lakh | 20% | Seniors (60–79): nil up to ₹3 lakh. Super seniors (80+): nil up to ₹5 lakh, then 20% and 30%. | |
| ₹20–24 lakh | 25% | ||
| Above ₹24 lakh | 30% | ||
- Rebate. In the new regime, tax is nil if taxable income is ₹12 lakh or less (rebate up to ₹60,000). Just above ₹12 lakh, marginal relief caps the tax at the amount your income exceeds ₹12 lakh. In the old regime, the rebate is up to ₹12,500 for income up to ₹5 lakh.
- Standard deduction. ₹75,000 (new) or ₹50,000 (old) for salary and pension. That is why a salary of ₹12.75 lakh pays no tax in the new regime.
- Surcharge. 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore; the old regime adds 37% above ₹5 crore. Marginal relief applies at each step.
- Cess. 4% health and education cess on the tax plus surcharge.
- Break-even. The calculator searches for the total of old-regime deductions (HRA, 80C, 80D, home loan interest and the rest, beyond the standard deduction) at which both regimes cost the same. Below that number, the new regime wins.
Can you switch regimes every year?
If your income is from salary, pension, interest or rent, yes. You choose each year when you file your return, whatever you told your employer for TDS. If you have business or professional income, you can opt out of the new regime and come back to it only once in your life, so that choice needs more care.
