Module C: Formula & Methodology Behind the Calculator
The calculator uses the exact methodology prescribed in the Income Tax Act 1961 as amended by Finance Act 2017. Here’s the detailed calculation process:
Step 1: Calculate Gross Total Income (GTI)
GTI = Income from Salary + Income from House Property + Income from Business/Profession + Capital Gains + Income from Other Sources
Step 2: Apply Chapter VI-A Deductions
Total Deductions = Section 80C + Section 80D + Other eligible deductions (80E, 80G, etc.)
Note: Section 80C has a maximum limit of ₹1,50,000. Any excess cannot be carried forward.
Step 3: Determine Taxable Income
Taxable Income = GTI – Total Deductions – Exemptions (HRA, LTA, etc.)
Step 4: Apply Tax Slabs Based on Age
| Age Group | Income Range | Tax Rate | Surcharge |
|---|---|---|---|
| Below 60 years | Up to ₹2,50,000 | Nil | – |
| ₹2,50,001 to ₹5,00,000 | 5% | – | |
| ₹5,00,001 to ₹10,00,000 | 20% | – | |
| Above ₹10,00,000 | 30% | 10% (if income > ₹50 lakh) | |
| 60-80 years | Up to ₹3,00,000 | Nil | – |
| ₹3,00,001 to ₹5,00,000 | 5% | – | |
| ₹5,00,001 to ₹10,00,000 | 20% | – | |
| Above ₹10,00,000 | 30% | 10% (if income > ₹50 lakh) |
Step 5: Calculate Tax Payable
Income Tax = (Taxable Income × Applicable Rate) – Rebate (if eligible)
Rebate under Section 87A: ₹5,000 or 100% of tax (whichever is lower) for income ≤ ₹3,50,000
Step 6: Add Surcharge and Cess
Total Tax = Income Tax + Surcharge (if applicable) + Education Cess (3% of Income Tax + Surcharge)

Module G: Interactive FAQ
What is the last date for filing ITR for AY 2018-19?
The due date for filing income tax returns for Assessment Year 2018-19 (Financial Year 2017-18) was July 31, 2018 for most taxpayers. However, the department extended it to August 31, 2018 for certain categories. Late filings could be submitted by March 31, 2019 with applicable penalties.
How do I calculate HRA exemption correctly for 2017-18?
The HRA exemption is the minimum of three amounts:
- Actual HRA received from employer
- 50% of salary (for metro cities) or 40% (for non-metro)
- Actual rent paid minus 10% of salary
Example: If your salary is ₹60,000/month (₹7,20,000/year), HRA is ₹20,000/month, and rent paid is ₹15,000/month in Delhi:
Exemption = min(₹20,000, ₹30,000, ₹15,000 – ₹6,000) = ₹9,000/month
Note: You must provide rent receipts and PAN of landlord if annual rent > ₹1 lakh.
What are the changes in tax slabs for senior citizens in 2017-18?
For Assessment Year 2018-19, the tax slabs for senior citizens (60-80 years) were:

- ₹5,00,001 to ₹10,00,000: 20%
- Above ₹10,00,000: 30%
For super senior citizens (above 80 years), the basic exemption limit was ₹5,00,000.
Key Change: The rebate under Section 87A was reduced from ₹5,000 (for income ≤ ₹5 lakh) to ₹5,000 (for income ≤ ₹3.5 lakh).
Can I claim both HRA and home loan benefits simultaneously?
Yes, you can claim both benefits under specific conditions:
- Different Properties: You must be living in a rented house (for HRA) while owning another property (for home loan benefits)
- Documentation: Maintain rent agreement and home loan statements
- Home Loan Benefits: You can claim:
- Principal repayment under Section 80C (max ₹1.5 lakh)
- Interest payment under Section 24(b) (max ₹2 lakh for self-occupied)
- Tax Implications: The rented property’s income will be taxable under “Income from House Property” after 30% standard deduction
Example: If you live in a rented apartment in Mumbai (₹30,000/month rent) and own a flat in Pune (₹25,000 EMI with ₹20,000 interest component), you can claim both HRA exemption and home loan interest deduction.
What is the treatment of long-term capital gains in 2017-18?

How does the 10% surcharge on incomes between ₹50 lakh to ₹1 crore work?

- Example Calculation:
- Taxable Income: ₹60,00,000
- Basic Tax: ₹13,00,000 (₹10L at 30% + ₹50L at 30%)
- Surcharge: 10% of ₹13,00,000 = ₹1,30,000
- Education Cess: 3% of (₹13,00,000 + ₹1,30,000) = ₹43,500
- Total Tax: ₹14,73,500
