⚡ Surcharge at a Glance – FY 2026-27
- Surcharge applies on income tax (not on income directly)
- Kicks in when total income exceeds ₹50 lakh
- New regime surcharge capped at 25% (for income above ₹2 crore)
- Old regime: up to 37% surcharge (for income above ₹5 crore)
- Marginal relief ensures you don’t pay more tax than your excess income
What is Surcharge?
Surcharge is a percentage of your computed income tax – applied when your total income exceeds specific thresholds. It is collected to increase tax revenue from high-income earners. After surcharge is applied, a Health and Education Cess of 4% is levied on (income tax + surcharge).
Formula: Total Tax = (Income Tax × Surcharge Rate) + 4% Cess on (Income Tax + Surcharge)
Surcharge Rates FY 2026-27 – New Tax Regime
| Total Income | Surcharge Rate (New Regime) |
|---|---|
| Up to ₹50 lakh | NIL |
| ₹50 lakh to ₹1 crore | 10% |
| ₹1 crore to ₹2 crore | 15% |
| Above ₹2 crore | 25% (capped – no higher rate) |
Surcharge Rates FY 2026-27 – Old Tax Regime
| Total Income | Surcharge Rate (Old Regime) |
|---|---|
| Up to ₹50 lakh | NIL |
| ₹50 lakh to ₹1 crore | 10% |
| ₹1 crore to ₹2 crore | 15% |
| ₹2 crore to ₹5 crore | 25% |
| Above ₹5 crore | 37% |
Key difference: The new tax regime caps surcharge at 25% (Budget 2023 change), making it advantageous for very high income earners (above ₹2 crore). Under old regime, the 37% surcharge pushes effective tax rate to over 42%.
Surcharge on Capital Gains – Special Rule
For income from capital gains under Sections 111A (STCG on equity) and 112A (LTCG on equity/MF), the maximum surcharge is capped at 15% regardless of total income level – applicable under both old and new regimes. This is a major benefit for investors with large capital gains.
What is Marginal Relief on Surcharge?
Marginal relief ensures that when your income crosses a surcharge threshold by a small amount, the additional tax payable does not exceed the additional income earned. This prevents a situation where crossing ₹50 lakh by ₹1,000 triggers a disproportionate tax spike.
Example of Marginal Relief
- Income: ₹51 lakh | Without marginal relief: Tax jumps by surcharge on the full ₹51L base
- Excess income over threshold: ₹51L − ₹50L = ₹1 lakh
- With marginal relief: Extra tax payable ≤ ₹1 lakh (the excess income)
- The surcharge is reduced so the net tax increase equals the income increase
Marginal relief is available at all income threshold points: ₹50L, ₹1Cr, ₹2Cr, and ₹5Cr (old regime).
Health & Education Cess – 4% on All
Health and Education Cess of 4% is levied on (income tax + surcharge). It applies to all taxpayers regardless of income level. Cess cannot be reduced by any deductions or rebates – it is always computed on the final (tax + surcharge) figure.
Effective Tax Rate for High Incomes (New Regime FY 2026-27)
| Income Level | Effective Tax Rate (approx.) |
|---|---|
| ₹30 lakh | ~25.2% |
| ₹60 lakh (10% surcharge) | ~30.1% |
| ₹1.5 crore (15% surcharge) | ~34.6% |
| ₹5 crore+ (25% surcharge, new regime) | ~39% |
