Module C: Formula & Methodology
The calculator uses the following step-by-step methodology compliant with IT Act 1961 for AY 2018-19:
1. Calculate Gross Total Income (GTI)
GTI = Income from Salary + House Property + Business/Profession + Capital Gains + Other Sources
2. Apply Deductions (Chapter VI-A)
Total Deductions = 80C + 80D + 80G + 80E + [Other eligible deductions]
3. Determine Taxable Income
Taxable Income = GTI – (Standard Deduction ₹40,000) – (Total Deductions)
4. Apply Tax Slabs (2017-18 Rates)
| Income Range | Below 60 | 60-80 Years | Above 80 |
|---|---|---|---|
| Up to ₹2,50,000 | Nil | Nil | Nil |
| ₹2,50,001 to ₹5,00,000 | 5% | Nil | Nil |
| ₹5,00,001 to ₹10,00,000 | 20% | 20% | Nil |
| Above ₹10,00,000 | 30% | 30% | 30% |
5. Calculate Surcharge
- 10% of income tax where total income > ₹50 lakh
- 15% of income tax where total income > ₹1 crore
6. Add Education Cess
3% of (Income Tax + Surcharge)
7. Final Tax Liability
Total Tax = Income Tax + Surcharge + Education Cess – Rebate (if eligible)
Module D: Real-World Examples
Case Study 1: Salaried Individual (Below 60)
- Annual Income: ₹8,50,000
- 80C Investments: ₹1,50,000 (PPF + LIC)
- HRA: ₹1,20,000 (actual HRA received)
- Home Loan Interest: ₹1,80,000
- Medical Insurance: ₹15,000
Calculation:
Taxable Income = ₹8,50,000 – ₹40,000 (std ded) – ₹1,50,000 (80C) – ₹1,20,000 (HRA) – ₹1,80,000 (home loan) – ₹15,000 (80D) = ₹3,45,000
Tax = ₹2,50,000 (nil) + ₹95,000 @5% = ₹4,750
Cess = 3% of ₹4,750 = ₹143
Total Tax = ₹4,893 (Effective rate: 0.58%)
Case Study 2: Senior Citizen (65 Years)
- Pension Income: ₹6,20,000
- Interest Income: ₹1,80,000
- 80C: ₹1,00,000 (Senior Citizen Savings Scheme)
- Medical Insurance: ₹20,000
- Medical Expenses: ₹30,000 (80DDB)
Calculation:
Taxable Income = ₹8,00,000 – ₹40,000 – ₹1,00,000 – ₹20,000 – ₹30,000 = ₹6,10,000
Tax = ₹3,00,000 (nil) + ₹2,10,000 @20% = ₹42,000
Cess = 3% of ₹42,000 = ₹1,260
Total Tax = ₹43,260 (Effective rate: 5.41%)
Case Study 3: High Net Worth Individual
- Business Income: ₹1,20,00,000
- Capital Gains: ₹25,00,000 (LTCG @20% with indexation)
- 80C: ₹1,50,000
- 80G Donations: ₹50,000 (50% eligible)
Calculation:
Taxable Income = ₹1,45,00,000 – ₹40,000 – ₹1,50,000 – ₹25,000 (80G) = ₹1,43,85,000
Tax = ₹10,00,000 @30% + ₹1,33,85,000 @30% = ₹43,15,500
Surcharge = 15% of ₹43,15,500 = ₹6,47,325
Cess = 3% of (₹43,15,500 + ₹6,47,325) = ₹1,49,577
Total Tax = ₹51,12,397 (Effective rate: 35.24%)
