Formula & Methodology Behind the Calculator
The Al Rahiman Income Tax Calculator 2018-19 uses the exact tax computation methodology prescribed by the Income Tax Department for AY 2019-20. Here’s the detailed breakdown:
1. Taxable Income Calculation
The formula for calculating taxable income is:
Taxable Income = (Gross Total Income) - (Standard Deduction) - (Chapter VI-A Deductions)
2. Tax Slabs for 2018-19 (Old Regime)
| Income Range | Below 60 years | 60 to 80 years | Above 80 years |
|---|---|---|---|
| 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% |
3. Tax Calculation Process
-
Determine Taxable Income:
Subtract all eligible deductions (standard deduction, 80C, 80D, etc.) from gross total income.
-
Apply Tax Slabs:
Calculate tax for each income slab separately and sum them up.
Example for income ₹7,50,000 (below 60 years):
- First ₹2,50,000: Nil
- Next ₹2,50,000: 5% = ₹12,500
- Remaining ₹2,50,000: 20% = ₹50,000
- Total tax before cess: ₹62,500
-
Add Education Cess:
Calculate 3% of the total tax amount as education cess.
Example: 3% of ₹62,500 = ₹1,875
-
Calculate Total Tax:
Sum of income tax and education cess.
Example: ₹62,500 + ₹1,875 = ₹64,375
-
Compute Effective Tax Rate:
Divide total tax by gross income and multiply by 100.
Example: (₹64,375 / ₹7,50,000) × 100 = 8.58%
4. Special Cases Handled
-
Rebate under Section 87A:
For individuals with income up to ₹3,50,000, rebate of ₹2,500 is available (100% of tax or ₹2,500, whichever is lower).
-
Surcharge:
For incomes above ₹50 lakh (10%), ₹1 crore (15%), though not applicable in most individual cases for 2018-19.
-
Marginal Relief:
Provided when income exceeds ₹50 lakh or ₹1 crore to ensure surcharge doesn’t make tax exceed the excess income.
5. Mathematical Validation
The calculator’s algorithm has been validated against:
- Official Income Tax Department calculators
- Chartered accountant-verified test cases
- Historical tax computation examples from AY 2019-20

Interactive FAQ: Your Tax Questions Answered
What is the last date for filing ITR for AY 2019-20 (FY 2018-19)?
The last date for filing income tax returns for AY 2019-20 (FY 2018-19) was July 31, 2019 for most taxpayers. However, the deadline was extended to August 31, 2019 for certain categories. Late filings could be done until March 31, 2020 with penalties.
For current years, the typical deadline is July 31 unless extended by the government. Always check the official Income Tax Department website for the most current information.
How is the standard deduction of ₹40,000 calculated in this calculator?
The standard deduction of ₹40,000 was introduced in Budget 2018 to replace:
- Transport allowance (₹1,600 per month or ₹19,200 annually)
- Medical reimbursement (₹15,000 annually)
In our calculator:
- We automatically apply ₹40,000 deduction for all salaried individuals
- This reduces your taxable income by ₹40,000 before calculating tax
- The benefit is available regardless of actual expenses incurred
Example: If your gross income is ₹6,00,000, your taxable income becomes ₹5,60,000 after standard deduction.
Can I claim both HRA and home loan benefits simultaneously?
Yes, you can claim both HRA (House Rent Allowance) and home loan benefits simultaneously under certain conditions:
Scenario 1: Living in Rented House (Not Your Own)
- You can claim full HRA exemption
- Can also claim home loan interest under Section 24(b) for a property you own (but don’t live in)
- The owned property will be considered “deemed to be let out”
Scenario 2: Living in Your Own House
- Cannot claim HRA (since you’re not paying rent)
- Can claim full home loan benefits (principal + interest)
Important Conditions:
- For HRA: Must have actual rent agreement and receipts
- For home loan: Property must be constructed/completed
- Cannot claim HRA for a property you own in the same city
Our calculator handles this by treating HRA and home loan benefits as separate deductions that can co-exist under the right circumstances.
