Module G: Interactive FAQ
What are the key differences between 2017-18 and current tax regimes?
The 2017-18 tax regime had several distinct features compared to current systems:
- No standard deduction: Instead had transport allowance (₹1,920/year) and medical reimbursement (₹15,000/year)
- Higher surcharge: 15% for income above ₹1 crore (now reduced to 10% in new regime)
- 80C limit: Same ₹1.5L limit but different investment options were popular (e.g., infrastructure bonds)
- No rebate: The ₹12,500 rebate under Section 87A was introduced later
- Different slab rates: 20% slab started at ₹5L (now starts at ₹6L in old regime)
The Union Budget documents provide complete historical comparisons.
How is HRA exemption calculated for 2017-18?
The HRA exemption is the minimum of three amounts:
- Actual HRA received from employer
- 50% of salary for metro cities (40% for non-metro)
- Rent paid minus 10% of salary
Where “salary” means basic + DA (if part of retirement benefits) + commission (if fixed % of turnover).
Example: For ₹50,000 basic in Mumbai with ₹20,000 HRA and ₹18,000 rent:
- Actual HRA: ₹20,000
- 50% of salary: ₹25,000
- Rent – 10% salary: ₹18,000 – ₹5,000 = ₹13,000
- Exemption = Minimum(20,000, 25,000, 13,000) = ₹13,000/month
Note: Rent receipts are mandatory for claims over ₹3,000/month.
