Module C: Formula & Methodology Behind the Calculator
Tax Slab Structure for FY 2017-18
| Income Range | Below 60 years | 60-80 years | Above 80 years |
|---|---|---|---|
| Up to ₹2,50,000 | 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% | ||
Calculation Process
The calculator follows this precise methodology:
- Gross Total Income (GTI):
GTI = Salary + House Property + Capital Gains + Business Income + Other Sources
- Total Deductions (TD):
TD = 80C + 80D + 24(b) + 80G + Other Chapter VI-A deductions
Note: Each deduction has specific limits and conditions
- Taxable Income (TI):
TI = GTI - TD - Standard Deduction (if applicable)
- Income Tax Calculation:
If TI ≤ ₹2,50,000: Tax = 0 If ₹2,50,000 < TI ≤ ₹5,00,000: Tax = (TI - ₹2,50,000) × 5% If ₹5,00,000 < TI ≤ ₹10,00,000: Tax = ₹12,500 + (TI - ₹5,00,000) × 20% If TI > ₹10,00,000: Tax = ₹1,12,500 + (TI - ₹10,00,000) × 30% - Surcharge (if applicable):
If ₹50,00,000 < TI ≤ ₹1,00,00,000: Surcharge = 10% of Income Tax If TI > ₹1,00,00,000: Surcharge = 15% of Income Tax - Education Cess:
Education Cess = (Income Tax + Surcharge) × 3%
- Rebate u/s 87A:
If TI ≤ ₹3,50,000: Rebate = ₹2,500 (limited to tax amount) Else: Rebate = 0 - Net Tax Payable:
Net Tax = (Income Tax + Surcharge + Cess) - Rebate

- Standard deduction: ₹40,000 benefit
- Rebate u/s 87A: ₹2,500 rebate if income ≤ ₹3.5L
However, the 10% surcharge on incomes between ₹50L-₹1Cr affected higher middle-class earners. Overall, taxpayers with income up to ₹5L saw tax savings of about ₹12,500-₹15,000.
What documents are required for claiming HRA exemption?

- Rent Agreement: Registered agreement showing terms
- Landlord’s PAN: Required if annual rent > ₹1,00,000

- You can claim:
- HRA exemption for rent paid on current residence
- Section 24 deduction for home loan interest (up to ₹2L)
