What is Surcharge?
Surcharge is calculated on income tax when total income exceeds the relevant threshold. Health and Education Cess at 4% is then calculated on income tax plus surcharge. Total income—not gross salary or CTC—determines the band.
Surcharge Slabs: New Tax Regime
• Up to ₹50 Lakhs: No surcharge • ₹50,00,001 – ₹1 Crore: 10% surcharge on income tax • ₹1,00,00,001 – ₹2 Crore: 15% surcharge on income tax • Above ₹2 Crore: 25% surcharge on income tax (capped at 25% under New Regime) Note: Under the New Tax Regime, the maximum surcharge is capped at 25% even for income above ₹5 Crore. The 37% super-rich surcharge has been effectively removed for New Regime taxpayers.
Surcharge Slabs: Old Tax Regime
• Up to ₹50 Lakhs: No surcharge • ₹50,00,001 – ₹1 Crore: 10% surcharge • ₹1,00,00,001 – ₹2 Crore: 15% surcharge • ₹2,00,00,001 – ₹5 Crore: 25% surcharge • Above ₹5 Crore: 37% surcharge The 37% surcharge under the Old Regime makes the effective top tax rate ~42.74% (30% + 37% surcharge + 4% cess).
The Surcharge Cliff Problem
Without relief, crossing a threshold would apply the new surcharge rate to the full relevant tax amount. Marginal relief prevents income tax plus surcharge from rising by more than the income above the threshold. Cess is calculated afterward, so the final post-cess difference can be 4% higher than that excess.
How Marginal Relief Works
Before cess, compare: 1. Income tax at current total income plus normal surcharge; and 2. Income tax plus surcharge at the lower threshold, plus the excess total income. Use the lower figure. Example under the default slabs, with ordinary total income of ₹50,10,000: base tax is ₹10,83,000. Tax at ₹50,00,000 is ₹10,80,000, so tax plus surcharge is limited to ₹10,90,000; the relieved surcharge is ₹7,000 rather than 10% of the whole base tax. Cess is then ₹43,600.
Practical Tips for High Earners
Do not manufacture deductions merely to cross a surcharge threshold; only eligible amounts supported by the relevant facts can reduce total income. Current Section 124 employer NPS contribution may be relevant within its regime-specific percentage and overall employer-contribution limits. The default regime caps the general individual surcharge rate at 25%, while the optional old regime can reach 37%. Surcharge attributable to tax on specified capital gains and dividend income is capped at 15%; other tax components can still use the ordinary band rate.
