Marginal Relief in Income Tax — Surcharge & 87A

What is Marginal Relief in Income Tax?
Marginal relief is a provision in Indian income tax law that prevents a situation where the tax payable (including surcharge or loss of rebate) exceeds the incremental income that caused the higher tax liability. In plain terms: you should never pay more extra tax than the extra income you earned above a threshold.
There are two distinct types of marginal relief applicable for AY 2026-27:
- Surcharge marginal relief — applies at ₹50L, ₹1Cr, ₹2Cr, ₹5Cr, and ₹10Cr income crossings in both old and new regime.
- Section 87A rebate marginal relief — new for Budget 2025 new regime; applies when income is between ₹12L and ~₹12.75L.
Both forms of marginal relief are automatically applied by the ITR filing utility — no separate declaration is required by the taxpayer.
Budget 2025 Key Change
Section 87A rebate raised to ₹60,000 under the new regime, making income up to ₹12 lakh effectively tax-free. Marginal relief now operates in the ₹12L–₹12.75L band to prevent cliff-edge tax jumps.
- Prevents tax > incremental income above threshold
- Auto-computed in ITR utility — no manual declaration
- Applies at 5 surcharge income levels
- Section 87A marginal relief: ₹12L–₹12.75L band
- Available in both old and new tax regimes (surcharge)
- AY 2026-27: 87A relief only in new regime
- TaxClue cross-checks computation before every filing
Surcharge Marginal Relief — How It Works
Surcharge is an additional levy on income tax applicable when total income crosses specified thresholds. The surcharge rates for individuals under both old and new regime (FY 2025-26) are:
| Income Range | Surcharge Rate | Marginal Relief Applies? | At Which Crossing? |
|---|---|---|---|
| Up to ₹50 Lakh | Nil | N/A | — |
| ₹50L – ₹1 Crore | 10% | Yes | Income just above ₹50L |
| ₹1 Cr – ₹2 Crore | 15% | Yes | Income just above ₹1 Cr |
| ₹2 Cr – ₹5 Crore | 25% | Yes | Income just above ₹2 Cr |
| ₹5 Cr – ₹10 Crore | 37% | Yes | Income just above ₹5 Cr |
| Above ₹10 Crore | 37% | Yes | Income just above ₹10 Cr |
Marginal Relief Formula (Surcharge)
Marginal Relief = Surcharge Payable − (Income above threshold)
If this value is negative, no relief is needed. Relief is given only when surcharge exceeds the extra income earned above the threshold. Net tax = Tax + Surcharge − Marginal Relief + 4% Cess.
Section 87A Marginal Relief — New Regime AY 2026-27
Under Budget 2025, the Section 87A rebate under the new regime was raised to ₹60,000, effectively making income up to ₹12 lakh tax-free. However, for income between ₹12L and ~₹12.75L, a sudden loss of the full ₹60,000 rebate would cause net tax to exceed the incremental income — marginal relief prevents this cliff effect.
| Income Level | Tax Before Rebate | 87A Rebate | Without Marginal Relief | With Marginal Relief |
|---|---|---|---|---|
| ₹12,00,000 | ₹60,000 | ₹60,000 | ₹0 | ₹0 |
| ₹12,10,000 | ₹63,000 | ₹60,000 (partial) | ₹3,000 (theoretical) | ₹3,000 (≤ ₹10,000 extra income) |
| ₹12,50,000 | ₹75,000 | ₹60,000 (partial) | ₹15,000 | ₹15,000 (≤ ₹50,000 extra income) |
| ₹12,75,000 | ₹82,500 | Nil (income > rebate limit) | ₹86,190 (with cess) | ₹75,000 (capped at income above ₹12L) |
| ₹13,00,000 | ₹90,000 | Nil | ₹93,600 | ₹93,600 (no relief needed) |
Marginal Relief Calculation — Step by Step
Example 1: ₹50.2L Income
Tax at 30% slabs = ₹12.73L. 10% surcharge = ₹1.273L. Income above ₹50L = ₹20,000. Since surcharge (₹1.273L) > incremental income (₹20,000), marginal relief = ₹1,073L − ₹20,000 = ₹1,053L is NOT applicable this way — relief = surcharge − incremental income = ₹1.07L. Net tax = tax + (surcharge − relief) + cess.
Example 2: ₹12.05L New Regime
Normal tax = ₹61,500. 87A rebate available = ₹60,000. Net tax after rebate = ₹1,500. Income above ₹12L = ₹5,000. Since net tax (₹1,500) < extra income (₹5,000), no marginal relief needed. Final tax = ₹1,500 + 4% cess = ₹1,560.
Example 3: ₹12.75L New Regime
Normal tax = ₹82,500. 87A rebate = Nil (income above rebate ceiling). Without relief, tax + cess = ₹85,800. Income above ₹12L = ₹75,000. Tax exceeds extra income by ₹10,800 — marginal relief of ₹10,800 applies. Net tax = ₹75,000 (capped).

How Marginal Relief is Applied in ITR
Auto-Computed
The ITR offline utility and e-filing portal automatically compute marginal relief in Schedule-SI and tax computation. No separate Schedule or declaration required.
Which ITR Forms
Marginal relief can appear in ITR-1, ITR-2, ITR-3, ITR-4, and ITR-5 depending on taxpayer type. It is reflected in the tax liability computation section.
TaxClue Cross-Check
Our CA team manually verifies the marginal relief computation before submitting every return, especially for clients with income near threshold boundaries (₹12L, ₹50L, ₹1Cr).
Old vs New Regime
In the old regime, 87A marginal relief applies near ₹5L income boundary. In the new regime (Budget 2025), it applies near the ₹12L boundary with a ₹60,000 rebate.
Cess on Marginal Relief
4% Health & Education Cess is computed after applying marginal relief. Cess is on (Income Tax + Surcharge − Marginal Relief), not on gross tax.
Advance Tax Relevance
For advance tax computation (quarterly), marginal relief should be factored into estimated tax liability to avoid 234B/234C interest on underpayment.
