Understanding Income Tax in India
India offers two tax regimes for individual taxpayers. The old regime has higher slab rates but allows numerous deductions and exemptions, while the new regime (default from FY 2023-24 onwards) offers lower slab rates with minimal deductions. Choosing the right regime can save you lakhs in tax every year.
New Regime Tax Slabs (FY 2025-26)
| Income Slab | Tax Rate |
|---|---|
| Up to ₹3,00,000 | Nil |
| ₹3,00,001 – ₹4,00,000 | 5% |
| ₹4,00,001 – ₹7,00,000 | 10% |
| ₹7,00,001 – ₹10,00,000 | 15% |
| ₹10,00,001 – ₹12,00,000 | 20% |
| ₹12,00,001 – ₹15,00,000 | 25% |
| Above ₹15,00,000 | 30% |
Standard deduction: ₹75,000 for salaried individuals under the new regime.
Old Regime Tax Slabs (FY 2025-26)
| Income Slab | Tax Rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |

| Above ₹10,00,000 | 30% |
Section 87A Rebate
The Section 87A rebate effectively makes income up to a certain threshold tax-free. Under the new regime for FY 2025-26, if your taxable income (after standard deduction) is up to ₹12 lakh, you pay zero tax. Under the old regime, the rebate is ₹12,500 for taxable income up to ₹5 lakh.
How to Choose Between Old and New Regime
The decision depends on your total deductions. If you claim significant deductions — HRA, Section 80C (₹1.5 lakh), 80D (health insurance), NPS 80CCD(1B) (₹50,000), and home loan interest — the old regime often results in lower tax. For those with fewer deductions or simpler tax situations, the new regime's lower rates and higher ₹12 lakh rebate threshold make it the better choice.
Use this calculator to enter your actual income and deduction figures and compare the tax under both regimes to make an informed decision.
