AY 2026-27 (FY 2025-26). Enter figures to see tax under both regimes.
This tool computes your income tax for Assessment Year 2026-27 (Financial Year 2025-26) under both the new and old regimes, then tells you which one leaves you paying less. Enter your gross annual income, choose whether it is salary or pension (which unlocks the standard deduction), and add the deductions you would claim under the old regime.
| Taxable income | Rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹4,00,001 to ₹8,00,000 | 5% |
| ₹8,00,001 to ₹12,00,000 | 10% |
| ₹12,00,001 to ₹16,00,000 | 15% |
| ₹16,00,001 to ₹20,00,000 | 20% |
| ₹20,00,001 to ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
Standard deduction ₹75,000 for salaried and pensioners. Section 87A rebate up to ₹60,000 makes taxable income up to ₹12 lakh tax-free. Marginal relief applies just above ₹12 lakh so a small rise in income never costs more in tax than the income gained.
| Taxable income | Rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 to ₹5,00,000 | 5% |
| ₹5,00,001 to ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
Standard deduction ₹50,000. Section 87A rebate ₹12,500 up to ₹5 lakh taxable income. The old regime only wins when your deductions, 80C, 80D, HRA, home loan interest, NPS, are large enough to offset its higher headline rates.
The rule of thumb: if your total deductions are modest, the new regime almost always wins because of its wider slabs and larger standard deduction. The old regime becomes worthwhile only when your deductions are substantial, typically once they cross roughly ₹3.5 to ₹4 lakh at higher incomes. This calculator does the exact comparison for your numbers, but if you want to understand the trade-off in depth, our old vs new regime guide walks through it with worked examples.
Take a salaried person earning ₹15,00,000 with ₹1,50,000 of 80C deductions. Under the new regime, taxable income is ₹14,25,000 after the ₹75,000 standard deduction, and tax works out to about ₹97,500 including 4% cess. Under the old regime, after the ₹50,000 standard deduction and ₹1,50,000 of 80C, taxable income is ₹13,00,000 and tax is roughly ₹2,10,600 including cess. Here the new regime saves over ₹1,13,000, because ₹1,50,000 of deductions is nowhere near enough to overcome the old regime's much higher rates. The old regime would only start to win once deductions climbed well above ₹3.5 lakh.
