Use our calculator to see which regime benefits you more based on your income and deductions.
How is surcharge calculated on income tax?
Surcharge is an additional tax on high-income individuals, calculated as a percentage of the income tax (before cess):
| Income Range | Surcharge Rate | Marginal Relief |
|---|---|---|
| ₹50 lakh – ₹1 crore | 10% | No |
| ₹1 crore – ₹2 crore | 15% | Yes |
| ₹2 crore – ₹5 crore | 25% | Yes |
| Above ₹5 crore | 37% | Yes |
Marginal Relief: Ensures surcharge doesn’t make the total tax exceed the income excess over the threshold. For example, if your income is ₹50.1 lakh, you won’t pay surcharge on the full amount – only on ₹1 lakh above the threshold.
What is Section 87A rebate and who can claim it?
Section 87A provides a tax rebate to resident individuals with income below certain limits:
- New Regime: Full rebate if taxable income ≤ ₹7 lakh (Budget 2023 enhancement)
- Old Regime: Rebate if taxable income ≤ ₹5 lakh (max rebate ₹12,500)
Eligibility:
- Must be a resident individual
- Not available to NRIs, Hindu Undivided Families (HUFs), or companies
- Automatically applied by the calculator if you qualify
Example: If your taxable income is ₹6.5 lakh in the new regime, you pay ₹0 tax due to the 87A rebate.
How does the standard deduction work in both regimes?
The standard deduction is a flat reduction from your gross income:
- Amount: ₹50,000 in both regimes (Budget 2023 made it available in new regime)
- Purpose: Replaces transport allowance (₹19,200) and medical reimbursement (₹15,000) from pre-2018 regime
- Eligibility: Available to all salaried individuals and pensioners
- Calculation: Deduct ₹50k from gross income before applying tax slabs
Example: If your salary is ₹10 lakh, your taxable income becomes ₹9.5 lakh after standard deduction in both regimes.
What documents do I need to file ITR after using this calculator?
After calculating your tax liability, gather these documents for ITR filing:

- Investment proofs (for 80C, 80D claims)

Yes, you can choose between regimes each financial year with these rules:
- Salaried Employees: Must inform employer at start of FY (Form 10IE)
- Business/Professionals: Can choose while filing ITR (no need to inform in advance)
- Default: New regime is now the default (Budget 2023)
- Exception: If you have business income, you can only switch once in your lifetime (from old to new)
Recommendation: Use this calculator annually to compare which regime is better based on your current income and deductions. The optimal choice may change year to year.
