Module C: Formula & Methodology
The income tax calculation for salaries in 2018-19 follows a specific methodology based on the Income Tax Act provisions. Here’s the detailed breakdown of how our calculator works:
1. Gross Salary Calculation
Gross Salary = Basic Pay + Dearness Allowance + House Rent Allowance + Transport Allowance + Other Allowances + Bonuses + Any other salary components
2. HRA Exemption Calculation
The least of the following three amounts is exempt from tax:
- Actual HRA received
- 50% of salary (for metro cities) or 40% of salary (for non-metro cities)
- Actual rent paid minus 10% of salary
3. Taxable Income Calculation
Taxable Income = Gross Salary – HRA Exemption – Standard Deduction (₹40,000) – Deductions under Chapter VI-A (80C, 80D, etc.)
4. Income Tax Calculation
The tax is calculated based on the following slabs for individuals below 60 years (2018-19):
| Income Range (₹) | Tax Rate | Surcharge |
|---|---|---|
| Up to 2,50,000 | Nil | Nil |
| 2,50,001 to 5,00,000 | 5% | Nil |
| 5,00,001 to 10,00,000 | 20% | Nil |
| Above 10,00,000 | 30% | 10% of tax if income > ₹50 lakh 15% of tax if income > ₹1 crore |
5. Education Cess
