Module C: Formula & Methodology Behind the Calculator
The calculator uses the exact tax computation methodology prescribed by the Income Tax Act, 1961 for FY 2017-18. Here’s the detailed mathematical approach:
1. Tax Slab Rates for FY 2017-18
| Age Group | Income Range | Tax Rate | Basic Exemption Limit |
|---|---|---|---|
| Below 60 years | Up to ₹2,50,000 | Nil | ₹2,50,000 |
| Below 60 years | ₹2,50,001 to ₹5,00,000 | 5% | ₹2,50,000 |
| Below 60 years | ₹5,00,001 to ₹10,00,000 | 20% | ₹2,50,000 |
| Below 60 years | Above ₹10,00,000 | 30% | ₹2,50,000 |
| 60 to 80 years | Up to ₹3,00,000 | Nil | ₹3,00,000 |
| Above 80 years | Up to ₹5,00,000 | Nil | ₹5,00,000 |
2. Tax Calculation Algorithm
The calculator follows this precise sequence:
-
Gross Total Income (GTI):
GTI = Income from Salary + Income from House Property + Income from Business/Profession + Capital Gains + Income from Other Sources
-
Total Deductions (TD):
TD = (80C + 80D + 80G + 24 + Other Deductions) subject to individual limits
Note: HRA exemption is calculated separately and deducted from salary income
-
Taxable Income (TI):
TI = GTI – TD – Standard Deduction (₹40,000 for salaried)
-
Income Tax (IT):
Calculated using slab rates on TI with marginal relief
Formula: IT = (TI × slab rate) + (previous slab tax)
-
Rebate (R):
R = min(₹2,500, IT) if TI ≤ ₹3,50,000
-
Education Cess (EC):
EC = 3% of (IT – R)
-
Total Tax (TT):
TT = (IT – R) + EC
3. Special Cases Handled
- Negative Taxable Income: Set to zero if deductions exceed GTI
- Marginal Relief: Applied when income exceeds ₹1 crore to limit surcharge impact
- Rounding: All values rounded to nearest rupee as per IT rules
- Alternative Minimum Tax: Not applicable for individuals in FY 2017-18
