Introduction & Importance of Income Tax Calculation in India (2018)
Understanding how income tax is calculated in India for the financial year 2018-19 (Assessment Year 2019-20) is crucial for every taxpayer.

- Revised tax slabs with different rates for different age groups
- Standard deduction of ₹40,000 for salaried employees

Formula & Methodology Behind the Calculation
The 2018-19 income tax calculation follows this precise methodology:

For 2018-19, a standard deduction of ₹40,000 was introduced for salaried employees and pensioners.
Step 2: Apply Appropriate Tax Slabs

| 60 to 80 years | Up to ₹3,00,000 | Nil | – |

| Above ₹10,00,000 | 30% | 10% (if income > ₹50 lakh) 15% (if income > ₹1 crore) |
Step 3: Calculate Tax with Slab Benefits
For incomes up to ₹5,00,000, taxpayers received a rebate under Section 87A:
- ₹2,500 rebate for income ≤ ₹3,50,000 (reduced to ₹2,000 for 2018-19)
- No rebate for income > ₹3,50,000

Final Tax = (Income Tax + Surcharge) + Education Cess (3% of income tax)
