Key Components of Tax Calculation

- Deductions (Chapter VI-A): Includes sections 80C (₹1.5 lakh), 80D (medical insurance), 80G (donations), etc.

HRA Calculation Methodology
House Rent Allowance (HRA) exemption is calculated as the minimum of:
- Actual HRA received
- 50% of salary (for metro cities) or 40% (for non-metros)
- Actual rent paid minus 10% of salary
Example: For an employee in Delhi with basic salary ₹50,000, HRA received ₹20,000, and rent paid ₹18,000:
- Actual HRA: ₹20,000
- 50% of salary: ₹25,000
- Rent paid – 10% salary: ₹18,000 – ₹5,000 = ₹13,000
- Exempt HRA: ₹13,000 (minimum of above)
