Interactive FAQ: 2018-19 Tax Calculation
What was the standard deduction introduced in Budget 2018? +
The Budget 2018 introduced a standard deduction of ₹40,000 for salaried employees and pensioners, replacing the earlier transport allowance (₹19,200) and medical reimbursement (₹15,000). This was designed to simplify tax calculations and provide relief to the salaried class.
Key points:
- Available to all salaried individuals and pensioners
- No need to submit any bills or proofs
- Reduces taxable income directly
- Not available for self-employed professionals
For example, if your salary income is ₹7,00,000, your taxable income would be reduced to ₹6,60,000 after applying the standard deduction.
How is long-term capital gains tax calculated on equity for 2018-19? +
Budget 2018 reintroduced the 10% long-term capital gains (LTCG) tax on equity investments with these rules:
- Applicability: Gains exceeding ₹1 lakh from sale of equity shares/units of equity-oriented mutual funds
- Holding Period: More than 12 months (changed from earlier 1 year = short-term)
- Calculation:
- Identify cost of acquisition (purchase price)
- Calculate indexed cost (not applicable for equity as per current rules)
- Determine sale consideration
- Capital gain = Sale price – Cost price
- Taxable LTCG = (Total LTCG – ₹1 lakh) × 10%
- Grandfathering: For shares acquired before 31 Jan 2018, the higher of:
- Actual cost price, or
- Fair market value as on 31 Jan 2018
Example: If you sold shares purchased at ₹2,00,000 for ₹5,00,000 in FY 2018-19:
- Capital Gain = ₹3,00,000
- Taxable Gain = ₹3,00,000 – ₹1,00,000 (exemption) = ₹2,00,000
- LTCG Tax = 10% of ₹2,00,000 = ₹20,000
What are the key differences between old and new tax regimes for 2018-19? +
For FY 2018-19, only the old tax regime was applicable. The new tax regime with lower rates and no exemptions was introduced in Budget 2020 (applicable from FY 2020-21 onwards).
Old Regime (2018-19) Features:
- Multiple tax slabs (5%, 20%, 30%) based on income levels
- Numerous exemptions and deductions available:
- Section 80C (₹1.5 lakh)
- Section 80D (medical insurance)
- HRA exemption
- LTA exemption
- Standard deduction (₹40,000)
- Higher basic exemption limits for senior citizens
- Rebate under Section 87A (₹2,500 for income ≤ ₹3.5 lakh)
- Surcharge applicable for high incomes (10% for ₹50L-₹1Cr, 15% for >₹1Cr)
The new regime introduced later offered lower tax rates but removed most exemptions and deductions, giving taxpayers a choice between the two systems.
How do I calculate surcharge and cess on my income tax? +
Surcharge and cess are calculated on top of your basic income tax liability:
Surcharge Calculation:
- Income between ₹50 lakh and ₹1 crore: 10% surcharge on income tax
- Income above ₹1 crore: 15% surcharge on income tax
- Marginal Relief: Ensures surcharge doesn’t exceed the amount by which income exceeds the threshold
- For ₹50L threshold: Surcharge = (Income – ₹50L) × 10%
- For ₹1Cr threshold: Surcharge = ₹5L + (Income – ₹1Cr) × 15%
Health & Education Cess:
- 4% of (Income Tax + Surcharge)
- Introduced in Budget 2018 (replaced 3% education cess)
Example Calculation:
For taxable income of ₹1,20,00,000:
- Income Tax: ₹34,47,500 (calculated as per slabs)
- Surcharge (15%): ₹5,17,125 [(₹34,47,500 × 15%)]
- Marginal Relief Check:
- Income exceeds ₹1Cr by ₹20,00,000
- Maximum surcharge = ₹20,00,000
- Calculated surcharge (₹5,17,125) is within limit
- Health & Education Cess: 4% of (₹34,47,500 + ₹5,17,125) = ₹1,58,370
- Total Tax Liability: ₹41,23,000
