Marginal Relief on Surcharge: How It Protects High-Income Taxpayers
Surcharge is an additional tax levied on the income tax of individuals whose total income exceeds specified thresholds. It was introduced to ensure that high-income earners contribute a proportionally higher amount to the exchequer. However, the application of surcharge at fixed thresholds can create an anomaly where a person earning marginally more than the threshold pays significantly higher total tax than someone earning just below the threshold. Marginal relief is the mechanism that addresses this anomaly.
Surcharge Rates for FY 2025-26
The surcharge rates for individual taxpayers are structured as follows: 10% on income tax when total income exceeds Rs 50 lakh but does not exceed Rs 1 crore; 15% when income exceeds Rs 1 crore but not Rs 2 crore; 25% when income exceeds Rs 2 crore but not Rs 5 crore; and 37% when income exceeds Rs 5 crore (under the old regime). Under the new tax regime, the maximum surcharge is capped at 25% for all income levels above Rs 2 crore, making the new regime more beneficial for ultra-high earners.
How Marginal Relief Works
The principle of marginal relief is straightforward: the total amount of tax including surcharge should not exceed the total tax payable at the threshold level plus the amount of income exceeding the threshold. In other words, the additional tax (including surcharge) on income above the threshold should not exceed 100% of the excess income. This prevents situations where earning Rs 1 extra could result in thousands of rupees in additional tax due to the surcharge kicking in.
Practical Example at the Rs 50 Lakh Threshold
Consider an individual with a total income of Rs 51,00,000 under the new regime. Tax on Rs 51,00,000 before surcharge would be approximately Rs 13,42,500. Surcharge at 10% = Rs 1,34,250. Total = Rs 14,76,750. Now, tax on Rs 50,00,000 (at the threshold) = Rs 13,12,500 with zero surcharge. The excess income is only Rs 1,00,000, but the tax increase is Rs 1,64,250 (Rs 14,76,750 - Rs 13,12,500), which exceeds the excess income of Rs 1,00,000. Marginal relief reduces the surcharge so that the total tax increase is capped at Rs 1,00,000, resulting in a lower total tax of Rs 14,12,500.
When Marginal Relief Does Not Apply
Marginal relief is most significant when income is just above a surcharge threshold. As income increases further beyond the threshold, the regular surcharge computation becomes more favourable than the marginal relief computation, and marginal relief ceases to apply. Typically, marginal relief becomes irrelevant once income exceeds the threshold by a margin of approximately 2-5% depending on the specific threshold and tax rates involved.
New Regime vs Old Regime Surcharge
A key difference between the regimes is the maximum surcharge rate. Under the old regime, the highest surcharge rate is 37% (for income above Rs 5 crore), while under the new regime, the maximum is capped at 25%. This means that for ultra-high-net-worth individuals with income above Rs 5 crore, the new regime offers a significant surcharge advantage. The effective maximum marginal rate under the new regime is approximately 39% (30% tax + 25% surcharge + 4% cess on the combined amount), compared to approximately 42.74% under the old regime.
Strategic Tax Planning Near Thresholds
Understanding marginal relief is crucial for tax planning near surcharge thresholds. In some cases, it may be beneficial to defer income or accelerate deductions to keep total income just below a threshold. For example, timing of capital gains realisation, bonus payments, or professional fee receipts can be planned to avoid triggering surcharge. However, such planning should be done within the legal framework and with professional advice to avoid allegations of tax avoidance.
