Module C: Formula & Methodology Behind the Calculation

1. Taxable Income Calculation

The formula follows this precise sequence:

Taxable Income = (Gross Income)
               - (Standard Deduction of ₹40,000)
               - (HRA Exemption)
               - (Chapter VI-A Deductions)
               - (Other Exemptions)

2. HRA Exemption Calculation

The least of these three values is considered:

1. Actual HRA received from employer
2. 50% of salary (metro) or 40% (non-metro)
3. Actual rent paid minus 10% of salary

3. Tax Calculation Logic

Income Range (₹)	Below 60	60-80 Years	Above 80
Up to 2,50,000	Nil	Up to 3,00,000: Nil	Up to 5,00,000: Nil
2,50,001 – 5,00,000	5%	5,00,001 – 5,00,000: 5%	5,00,001 – 10,00,000: 20%
5,00,001 – 10,00,000	20%	5,00,001 – 10,00,000: 20%	Above 10,00,000: 30%
Above 10,00,000	30%	Above 10,00,000: 30%	–

4. Surcharge and Cess

• Surcharge:
  • 10% for income between ₹50 lakhs to ₹1 crore
  • 15% for income above ₹1 crore
• Education Cess: 3% of (Income Tax + Surcharge)
• Rebate: ₹2,500 or 100% of tax (whichever is lower) for income ≤ ₹3.5 lakhs

• Introduction of ₹40,000 standard deduction (replacing ₹19,200 transport + ₹15,000 medical)
• Rebate under Section 87A reduced from ₹5,000 to ₹2,500

How is HRA exemption calculated for 2017-18? ▼

The HRA exemption is the minimum of these three amounts:

2. 50%/40% of Salary:
   • 50% if you live in Delhi, Mumbai, Chennai, or Kolkata
   • 40% for all other cities

   Salary = Basic + DA (if part of retirement benefits) + Commission (if fixed % of turnover)

3. Actual Rent Paid – 10% of Salary: Your annual rent minus 10% of your salary

Example: If your salary is ₹8,00,000, HRA is ₹2,40,000, and rent is ₹3,00,000 in Bangalore:

• Actual HRA: ₹2,40,000
• 50% of salary: ₹4,00,000
• Rent – 10% salary: ₹3,00,000 – ₹80,000 = ₹2,20,000
• Exemption: ₹2,20,000 (minimum of above)
