Module G: Interactive FAQ – Your Tax Questions Answered
What is the standard deduction introduced in Budget 2018?
The standard deduction of ₹40,000 was reintroduced in Budget 2018 to replace the earlier transport allowance (₹19,200) and medical reimbursement (₹15,000). This provides a flat deduction to all salaried taxpayers and pensioners, simplifying tax calculations. For example, if your gross salary is ₹8,00,000, your taxable income would be reduced to ₹7,60,000 after applying the standard deduction.
How is HRA exemption calculated for 2018-19?
HRA exemption is the minimum of three amounts:
- Actual HRA received from employer
- 50% of salary (for metro cities) or 40% (for non-metro)
- Actual rent paid minus 10% of salary
Example: If your basic salary is ₹50,000/month, HRA is ₹25,000, and rent paid is ₹20,000 in Delhi:
- Actual HRA: ₹25,000
- 50% of salary: ₹25,000
- Rent – 10% salary: ₹20,000 – ₹5,000 = ₹15,000
The exemption would be ₹15,000 per month.
What are the key differences in tax slabs for senior citizens?
| Age Group | Basic Exemption | Tax Rates |
|---|---|---|
| Below 60 | ₹2,50,000 |
|
| 60-80 years | ₹3,00,000 |
|
| Above 80 | ₹5,00,000 |
|
Senior citizens also get higher deduction limits for medical insurance (₹50,000 under 80D) and medical treatment of specified diseases (₹1,00,000 under 80DDB).
How does the new LTCG tax on equity affect investors?
From April 1, 2018, long-term capital gains (LTCG) on equity shares and equity-oriented mutual funds exceeding ₹1 lakh in a financial year are taxed at 10% without indexation benefits. Key points:
- Gains up to ₹1 lakh are exempt
- Grandfathering provision: Gains up to January 31, 2018 are exempt
- STT-paid deliveries are considered for exemption
- Dividend income remains tax-free in hands of investors (DDT paid by companies)
Example: If you sell shares purchased in 2016 for ₹5,00,000 with sale value ₹12,00,000 in 2018-19:
- Fair market value as on 31/01/2018: ₹8,00,000
- Taxable gain: ₹12,00,000 – ₹8,00,000 = ₹4,00,000
