Interactive FAQ: Your FY 2018-19 Tax Questions Answered
What was the standard deduction for salaried employees in FY 2018-19?
For FY 2018-19, the standard deduction was ₹40,000 for salaried employees and pensioners. This was introduced in Budget 2018 to replace the previous transport allowance (₹19,200) and medical reimbursement (₹15,000) exemptions.
The standard deduction directly reduces your taxable salary income. For example, if your salary income was ₹8,00,000, only ₹7,60,000 would be subject to tax after applying the standard deduction.
Note: This was different from the ₹50,000 standard deduction introduced in FY 2019-20.
How were long-term capital gains taxed in FY 2018-19?
FY 2018-19 marked a significant change in LTCG taxation:
- Equity Shares/Mutual Funds: LTCG exceeding ₹1 lakh were taxed at 10% without indexation benefit. Gains up to ₹1 lakh were exempt.
- Debt Funds: LTCG taxed at 20% with indexation benefit (or 10% without indexation, whichever was lower)
- Property: LTCG taxed at 20% with indexation benefit
- Gold: LTCG taxed at 20% with indexation benefit
The holding period for LTCG was:
- Equity: >12 months
- Debt funds/Property: >36 months
For calculation: LTCG = Sale Price – (Cost of Acquisition × CII of sale year/CII of purchase year)
What were the surcharge rates for high-income individuals in FY 2018-19?
The surcharge rates for FY 2018-19 were structured as follows:
| Income Range (₹) | Surcharge Rate | Effective Tax Rate |
|---|---|---|
| Up to 50,00,000 | 0% | As per slab |
| 50,00,001 – 1,00,00,000 | 10% | 33% (30% + 10% surcharge) |
| Above 1,00,00,000 | 15% | 34.5% (30% + 15% surcharge) |
Important notes:
- Surcharge is calculated on the income tax amount (before cess)
- Marginal relief is available to ensure surcharge doesn’t make tax liability exceed the excess income over ₹50 lakh/₹1 crore
- Health & Education Cess (4%) is applied on (Income Tax + Surcharge)
Example: For income of ₹1,20,00,000:
- Income Tax: ₹30,00,000 × 30% = ₹9,00,000
- Surcharge: ₹9,00,000 × 15% = ₹1,35,000
- Cess: (₹9,00,000 + ₹1,35,000) × 4% = ₹41,400
- Total Tax: ₹9,00,000 + ₹1,35,000 + ₹41,400 = ₹10,76,400
