Surcharge on Income Tax

What is Surcharge on Income Tax?

Surcharge applies to the income tax amount, not the income itself. Slabs for FY 2025-26: 10% if total income is between ₹50 lakh and ₹1 crore; 15% between ₹1 crore and ₹2 crore; 25% above ₹2 crore (new regime) or above ₹2 crore but below ₹5 crore in old regime; 37% above ₹5 crore (old regime only). The Finance Act 2023 capped maximum surcharge at 25% under the new regime. So very high earners often save lakhs by switching to the new regime. There's also a marginal relief rule: if your income just crosses a slab and the extra tax (income tax + surcharge) is more than the income above the threshold, you only pay tax up to that excess. This prevents weird situations where earning ₹1 extra costs you lakhs in extra tax. Health and Education Cess of 4% is then applied on top of the income tax plus surcharge.

Example

Mahesh earns ₹1.2 crore taxable income under the new regime. Tax before surcharge (rough): around ₹31,12,500. Surcharge at 15%: ₹4,66,875. Cess at 4% on (tax + surcharge): around ₹1,43,175. Total tax: about ₹37,22,550.

How Surcharge on Income Tax is used

Payroll engines compute surcharge month by month for high earners and adjust TDS. Marginal relief is applied automatically when income hovers around a threshold like ₹50 lakh or ₹1 crore.

Surcharge on Income Tax FAQs

Does surcharge apply to everyone?

No. It only applies if your taxable income crosses ₹50 lakh in a financial year.

Why is the new regime better for super-high earners?

Because the new regime caps surcharge at 25%, while the old regime can still go up to 37% above ₹5 crore. The savings on a ₹6+ crore income can be significant.

What is marginal relief?

A rule that limits how much extra tax you pay if your income just crosses a surcharge threshold, so the total extra tax cannot exceed the income above the threshold.
