Income Tax Calculator ā FY 2025-26
This calculator helps you estimate your income tax liability for Financial Year 2025-26 (Assessment Year 2026-27) under both the new tax regime (default) and the old tax regime. It includes the Section 87A rebate and 4% health and education cess.
New Tax Regime Slabs (FY 2025-26)
| Income Slab | Tax Rate |
|---|---|
| Up to ā¹4,00,000 | Nil |
| ā¹4,00,001 ā ā¹8,00,000 | 5% |
| ā¹8,00,001 ā ā¹12,00,000 | 10% |
| ā¹12,00,001 ā ā¹16,00,000 | 15% |
| ā¹16,00,001 ā ā¹20,00,000 | 20% |
| ā¹20,00,001 ā ā¹24,00,000 | 25% |
| Above ā¹24,00,000 | 30% |
Under the new regime, a standard deduction of ā¹75,000 applies, and income up to ā¹12,00,000 (taxable income) is effectively tax-free due to the Section 87A rebate.
Old Tax Regime Slabs
| Income Slab | Tax Rate |
|---|---|
| Up to ā¹2,50,000 | Nil |
| ā¹2,50,001 ā ā¹5,00,000 | 5% |
| ā¹5,00,001 ā ā¹10,00,000 | 20% |
| Above ā¹10,00,000 | 30% |
Under the old regime, you get a ā¹50,000 standard deduction and can claim deductions under 80C, 80D, HRA, etc.
Worked Example: New Regime
Suppose your annual income is ā¹18,00,000 under the new regime for FY 2025-26:
0ā4L: Nil
4Lā8L @ 5% = ā¹20,000
8Lā12L @ 10% = ā¹40,000
12Lā16L @ 15% = ā¹60,000
16Lā17.25L @ 20% = ā¹25,000
Total tax = ā¹1,45,000 + 4% cess (ā¹5,800) = ā¹1,50,800
Since taxable income here is above ā¹12,00,000, the Section 87A rebate does not apply and tax is charged slab-wise as shown above.
Worked Example: Old Regime
For an income of ā¹10,00,000 under the old regime (with only the standard ā¹50,000 deduction and no other 80C/HRA claims):
0ā2.5L: Nil
2.5Lā5L @ 5% = ā¹12,500
5Lā9.5L @ 20% = ā¹90,000
Total tax = ā¹1,02,500 + 4% cess (ā¹4,100) = ā¹1,06,600
Claiming deductions like 80C (ā¹1.5L) or HRA under the old regime would reduce this taxable income further, potentially lowering the tax below what the new regime charges ā this is why comparing both regimes with your actual deduction amounts (using the calculator above) matters before choosing.
