Income Tax A.Y. 2018-19 Calculator (Finotax)
Introduction & Importance of Income Tax A.Y. 2018-19 Calculation

Formula & Methodology Behind the Calculation
The Finotax calculator uses the exact tax computation methodology prescribed by the Income Tax Department for A.Y. 2018-19. Here’s the detailed breakdown:
Step 1: Calculate Gross Total Income
Sum of all income under five heads:
- Income from Salary: Gross salary including basic, DA, HRA, allowances, bonuses, etc.
- Income from House Property: Annual value of property minus municipal taxes and 30% standard deduction
- Income from Business/Profession: Net profit after allowed deductions
- Income from Capital Gains: Both short-term and long-term gains from asset sales
- Income from Other Sources: Interest income, dividends, gifts, etc.
Step 2: Apply Deductions (Chapter VI-A)
Subtract eligible deductions from Gross Total Income to arrive at Total Income:
| Section | Deduction Type | Maximum Limit (₹) | Notes |
|---|---|---|---|
| 80C | Investments & Expenses | 1,50,000 | PPF, ELSS, LIC, tuition fees, home loan principal, etc. |
| 80D | Medical Insurance | 25,000 (self) 50,000 (senior citizens) |
Additional ₹5,000 for preventive health checkup |
| 80G | Donations | Varies (50%-100%) | Depends on donee organization |
| 80E | Education Loan | No limit | Interest on education loan for higher studies |
| 80TTA | Savings Interest | 10,000 | Interest from savings accounts |
Step 3: Determine Taxable Income
Taxable Income = Total Income – Standard Deduction (₹40,000 for salaried)
Step 4: Apply Tax Slabs (A.Y. 2018-19)
| Income Range (₹) | Below 60 years | 60-80 years | Above 80 years |
|---|---|---|---|
| Up to 2,50,000 | Nil | Nil | Nil |
| 2,50,001 – 5,00,000 | 5% | Nil | Nil |
| 5,00,001 – 10,00,000 | 20% | 20% | Nil |
| Above 10,00,000 | 30% | 30% | 30% |
Surcharge: 10% of income tax where total income exceeds ₹50 lakh
15% of income tax where total income exceeds ₹1 crore
Health & Education Cess: 4% of (Income Tax + Surcharge)
Step 5: Calculate Final Tax Liability
Final Tax = (Income Tax + Surcharge) + Health & Education Cess

Interactive FAQ
What is the difference between Assessment Year and Financial Year?
The Financial Year (F.Y.) is the period from April 1 to March 31 when you earn income. The Assessment Year (A.Y.) is the following year when you file taxes for that income.
Example: For income earned between April 1, 2017, and March 31, 2018 (F.Y. 2017-18), you file taxes in A.Y. 2018-19 (by July 31, 2018, or extended deadline).
This calculator is specifically for income earned in F.Y. 2017-18, filed in A.Y. 2018-19.
How is the standard deduction of ₹40,000 calculated for salaried employees?
The standard deduction was reintroduced in Budget 2018 to replace:
- Transport allowance (₹1,600/month = ₹19,200/year)
- Medical reimbursement (₹15,000/year)
The ₹40,000 standard deduction is:
- Available to all salaried employees and pensioners
- Deductible from gross salary before calculating taxable income
- No need to submit any bills or proofs
- Not available for self-employed professionals
For example: If your gross salary is ₹10,00,000, your taxable salary income becomes ₹9,60,000 after standard deduction.
What are the tax implications for NRIs in A.Y. 2018-19?
For NRIs (Non-Resident Indians) in A.Y. 2018-19:
- Taxable Income: Only income earned or accrued in India

NRIs should use ITR-2 or ITR-3 for filing returns, depending on their income sources.
How is long-term capital gains tax calculated for A.Y. 2018-19?
A.Y. 2018-19 introduced significant changes to LTCG tax:
- Equity Shares/Mutual Funds:
- LTCG > ₹1 lakh taxed at 10% without indexation
- Grandfathering: Gains up to January 31, 2018, are exempt
- Example: If you bought shares at ₹100 and sold at ₹200:
- Fair market value on Jan 31, 2018: ₹150
- Taxable gain: ₹200 – ₹150 = ₹50 (if total LTCG > ₹1 lakh)
- Debt Mutual Funds:
- LTCG taxed at 20% with indexation
- Indexation adjusts purchase price for inflation
- Holding period: >36 months for LTCG
- Property:
- LTCG taxed at 20% with indexation
