Worked Example
Example: ₹15,00,000 Salaried Income under New Regime
Calculate final tax liability after standard deduction.
- Apply Salaried Standard Deduction: ₹15,00,000 - ₹75,000 = ₹14,25,000 taxable base.
- Slab 1 (0-4L): ₹0 tax.
- Slab 2 (4-8L): 5% of 4L = ₹20,000.
- Slab 3 (8-12L): 10% of 4L = ₹40,000.
- Slab 4 (12-14.25L): 15% of 2.25L = ₹33,750.
- Sum base tax: ₹20,000 + ₹40,000 + ₹33,750 = ₹93,750.
- Add 4% Health Cess: ₹93,750 * 1.04 = ₹97,500 total tax.
