Interactive FAQ About Income Tax Calculation
Which tax regime is better for me – old or new?
The better regime depends on your income level and eligible deductions:
- Choose New Regime if: Your income is below ₹15 lakh AND you have minimal deductions. The new regime offers lower rates and simpler filing.
- Choose Old Regime if: Your income is above ₹15 lakh OR you have significant deductions (home loan, investments, medical insurance).
Our calculator automatically shows which regime is better for your specific situation. For most salaried individuals with income below ₹12 lakh, the new regime is more beneficial.
How is surcharge calculated on income tax?
Surcharge is an additional tax levied on the income tax amount (not on total income) based on your income level:
| Income Range | Surcharge Rate |
|---|---|
| ₹50 lakh – ₹1 crore | 10% |
| ₹1 crore – ₹2 crore | 15% |
| ₹2 crore – ₹5 crore | 25% |
| Above ₹5 crore | 37% |
Example: If your income tax is ₹10 lakh and total income is ₹1.2 crore, surcharge = 15% of ₹10 lakh = ₹1.5 lakh.
What is the Section 87A rebate and who can claim it?
Section 87A provides tax rebates to resident individuals:
- New Regime: Full rebate if taxable income ≤ ₹7 lakh (max rebate ₹25,000)
- Old Regime: Full rebate if taxable income ≤ ₹5 lakh (max rebate ₹12,500)
Eligibility:
- Must be a resident individual (not HUF, firm, etc.)
- Total income after deductions must be within the limit
- Rebate is applied automatically by the calculator
Note: The rebate is applied to the tax amount, not the income. If your tax is ₹15,000 under new regime with income ₹7 lakh, you pay ₹0 tax.
How are capital gains taxed in India?
Capital gains tax depends on the asset type and holding period:
| Asset Type | Short-Term (<24/36 months) | Long-Term |
|---|---|---|
| Equity Shares/MF | 15% (STCG) | 10% above ₹1 lakh (LTCG) |
| Debt MF | As per slab | 20% with indexation |
| Property | As per slab | 20% with indexation |
| Gold | As per slab | 20% with indexation |
Important Notes:
- Holding period for equity: 12 months (24 months for immovable property)
- Indexation benefit available for long-term assets (except equity)
- STCG on equity is flat 15% regardless of your tax slab
