Section 115BAC of the Income-tax Act, 1961 -- the new regime slab structure post Finance Act, 2025; the Section 87A rebate raised to Rs 60,000 with the income threshold of Rs 12 lakh; the Rs 75,000 standard deduction; the resulting Rs 12.75 lakh effective threshold below which a salaried assessee pays zero income-tax; and the marginal relief that protects the slightly-above-Rs-12-lakh assessees
Taxpayer Brief
The Finance Act, 2025 made the most consequential change to Indian individual taxation in over a decade -- raising the section 87A rebate under the new regime to rupees sixty thousand and the income threshold to rupees twelve lakh, with a marginal relief mechanism for incomes slightly above the threshold. Combined with the rupees seventy-five thousand standard deduction available to salaried assessees under the new regime, the result is a 'sweet spot' at gross salary of rupees twelve lakh seventy-five thousand below which a salaried assessee pays zero income-tax under the new regime. This article maps the framework, the marginal relief computation for salaries between rupees twelve lakh seventy-five thousand and rupees twelve lakh seventy-eight thousand (approximate marginal-relief band), and the strategic implications for compensation structuring.
Complexity Matrix
Feature | Complexity Level | Primary Risk |
|---|---|---|
Salaried, gross salary up to Rs 12.75 lakh | Low | Default new regime; section 87A full rebate |
Salaried, gross salary Rs 12.75 lakh to Rs 12.78 lakh (approx) | Medium | Marginal relief computation |
Salaried, gross salary Rs 12.78 lakh to Rs 13 lakh (approx) | High | Marginal relief tapering; check both regimes |
Salaried with House Rent Allowance / Section 80C heavy structure | Very High | Old vs new regime comparative; new regime denies most deductions |
1. The Section 115BAC New Regime Slab -- Tax Year 2026-27
Slab | Rate (Section 115BAC, post Finance Act, 2025) |
|---|---|
Up to ₹4,00,000 | Nil |
₹4,00,001 to ₹8,00,000 | 5% |
₹8,00,001 to ₹12,00,000 | 10% |
₹12,00,001 to ₹16,00,000 | 15% |
₹16,00,001 to ₹20,00,000 | 20% |
₹20,00,001 to ₹24,00,000 | 25% |
Above ₹24,00,000 | 30% |
2. The Section 87A Rebate Mechanism
Sub-section (1) of section 87A of the Income-tax Act, 1961, as amended by the Finance Act, 2025, provides a rebate of up to rupees sixty thousand from the income-tax computed on the total income, where the total income (under the new regime) does not exceed rupees twelve lakh. The rebate is applied after computing the slab tax but before adding the Health and Education Cess. Where the total income marginally exceeds rupees twelve lakh, sub-section (2) of section 87A read with departmental clarifications provides marginal relief such that the increase in tax cannot exceed the increase in income.
3. The Standard Deduction
Section 16(ia) of the Income-tax Act, 1961 read with the Finance Act, 2024 amendment provides a standard deduction of rupees seventy-five thousand from Salary income for assessees opting for the new regime under section 115BAC. The Finance Act, 2024 raised the new-regime standard deduction from rupees fifty thousand to rupees seventy-five thousand effective from Tax Year 2024-25 onwards. The deduction is available regardless of whether the actual employer-related expenses exceed this amount.
4. The Sweet Spot Computation
Combine the rupees seventy-five thousand standard deduction with the rupees twelve lakh section 87A rebate threshold. A salaried assessee with gross salary up to rupees twelve lakh seventy-five thousand has total income (after standard deduction) up to rupees twelve lakh -- exactly at the section 87A rebate ceiling. The slab tax is computed; the rebate wipes out the tax in full; the cess applies on zero -- the total tax payable is nil.
Computation Step | Rs 12.75 Lakh Gross Salary |
|---|---|
Gross Salary | ₹12,75,000 |
Less: Standard deduction under section 16(ia) | (₹75,000) |
Total Income (under new regime) | ₹12,00,000 |
Slab tax computation | Nil up to ₹4L + 5% × ₹4L (4-8L) + 10% × ₹4L (8-12L) = ₹0 + ₹20,000 + ₹40,000 = ₹60,000 |
Section 87A rebate (total income up to ₹12L) | (₹60,000) |
Tax after rebate | ₹0 |
Health and Education Cess at 4% | ₹0 |
Total tax payable | Zero |
The asymmetry under the old regime Under the old regime, the section 87A rebate is rupees twelve thousand five hundred and the threshold is rupees five lakh of total income. The standard deduction is rupees fifty thousand. The corresponding old-regime sweet spot is therefore rupees five lakh fifty thousand of gross salary -- vastly less generous than the new regime's rupees twelve lakh seventy-five thousand. For most salaried employees up to the rupees twelve lakh seventy-five thousand level, the new regime is decisively the better choice. |
5. Marginal Relief -- The Slightly-Above-Threshold Band
Where total income marginally exceeds rupees twelve lakh, the section 87A rebate is unavailable -- but if applied directly, the tax would jump from zero to rupees sixty thousand for the first rupee of income above the threshold. Sub-section (2) of section 87A provides marginal relief: the tax payable cannot exceed the amount by which the total income exceeds rupees twelve lakh. This produces a tapered band where each additional rupee of income up to a certain point produces only one rupee of additional tax -- fully tapered at approximately rupees twelve lakh seventy-eight thousand (where the slab tax catches up to the marginal-relief cap).
Total Income | Slab Tax | Section 87A Rebate Available? | Marginal Relief Cap | Tax Payable |
|---|---|---|---|---|
₹12,00,000 | ₹60,000 | Yes -- full ₹60,000 rebate | Not applicable | Zero |
₹12,01,000 | ₹60,150 | No -- above threshold | Cannot exceed ₹1,000 (excess over ₹12L) | ₹1,000 |
₹12,10,000 | ₹61,500 | No | Cannot exceed ₹10,000 | ₹10,000 |
₹12,50,000 | ₹67,500 | No | Cannot exceed ₹50,000 | ₹50,000 |
₹12,77,000 (marginal relief catches up) | ₹71,550 | No | Slab tax now below marginal cap; standard slab tax applies | ₹71,550 + 4% Cess |
₹13,00,000 | ₹75,000 | No | Standard slab tax | ₹75,000 + 4% Cess = ₹78,000 |
The cliff-edge avoidance Without marginal relief, a one-rupee increase from rupees twelve lakh to rupees twelve lakh and one rupee would push the tax from zero to rupees sixty thousand -- a confiscatory marginal rate of 6 million per cent. Marginal relief converts this cliff edge into a smooth taper: each additional rupee of income produces approximately one rupee of additional tax until the slab tax naturally catches up around rupees twelve lakh seventy-seven thousand to seventy-eight thousand. Practitioners advising clients near the rupees twelve lakh threshold should be aware of this taper. |
6. Strategic Implications for Compensation Structuring
Strategy | Effect |
|---|---|
Cap gross salary at exactly ₹12,75,000 | Zero tax under new regime; maximum take-home |
Compensation between ₹12,75,000 and ₹15,00,000 | Marginal relief band followed by standard slab tax; consider whether new regime is still better than old |
Above ₹15,00,000 | New regime continues to apply but the section 87A advantage is lost; full slab tax applies |
For employees deliberately just above the threshold | Negotiate compensation structure with employer to bring total income to ₹12 lakh exactly -- defer bonus / shift to in-kind perquisites that have lower Rule 3 valuations |
7. The New Regime versus Old Regime -- When Old Wins Above Rs 12.75 Lakh
The new regime sweet spot is decisive up to rupees twelve lakh seventy-five thousand of gross salary. Above this level, the choice between old and new regime depends on the employee's specific deduction profile. The old regime rewards employees with -- (i) significant Chapter VI-A deductions (section 80C up to ₹1.5 lakh + 80D up to ₹50,000 + 80CCD(1B) NPS up to ₹50,000 = ₹2.5 lakh); (ii) House Rent Allowance exemption (often ₹2-5 lakh); (iii) section 24(b) home-loan interest (up to ₹2 lakh self-occupied); (iv) Leave Travel Concession exemption. The break-even depends on the aggregate of these claims.
Gross Salary Band | Old Regime Wins When | New Regime Wins When |
|---|---|---|
Up to ₹12,75,000 | Almost never (new regime sweet spot) | Almost always |
₹12,75,000 to ₹17,00,000 | Aggregate deductions + exemptions exceed approximately ₹3-4 lakh | Aggregate deductions + exemptions are below approximately ₹3 lakh |
₹17,00,000 to ₹25,00,000 | Aggregate above approximately ₹5 lakh | Aggregate below approximately ₹4-5 lakh |
Above ₹25,00,000 | Aggregate above approximately ₹6 lakh (especially with home-loan interest) | Aggregate below approximately ₹5-6 lakh |
8. Practitioner Guidance for the Salaried Executive
- Compute total income under both regimes annually using actual numbers.
- Where gross salary is up to ₹12.75 lakh, default to new regime -- the sweet spot is decisive.
- Where gross salary is between ₹12.75 lakh and ₹15 lakh, run the comparative computation; a moderate House Rent Allowance + 80C package can flip the decision back to old regime.
- Above ₹15 lakh -- aggregate deduction profile determines the optimal regime.
- Watch the marginal-relief band (₹12 lakh to approximately ₹12.78 lakh) -- any compensation negotiation should target either zero tax (just below ₹12 lakh) or accept the standard taper above.
- File the regime declaration in Form 10-IEA only where electing OUT of the default new regime; the new regime applies automatically without declaration.
9. Case Law Reference and Anticipatory Legal Analysis
Case Law Reference: Section 87A rebate and the marginal-relief mechanism Section 87A of the Income-tax Act, 1961 (rebate; inserted by the Finance Act, 2014 and successively raised by the Finance Acts 2019, 2023, and 2025) provides a tax rebate up to a specified amount where the total income does not exceed a threshold. The Finance Act, 2025 expanded the rebate to rupees sixty thousand for total income up to rupees twelve lakh under the new regime. The Income Tax Appellate Tribunal Mumbai in [VERIFY: confirm Tribunal citation on the section 87A rebate computation -- e.g., proceedings on the rebate-vs-marginal-relief interaction] applied the strict-construction principle to the threshold. The Karnataka High Court in [VERIFY: confirm High Court ruling on the marginal-relief mechanism] addressed the smooth-taper marginal-relief mechanic above the rupees twelve lakh threshold. [VERIFY: cross-check specific Tribunal and High Court citations in the BharatTax case-law database.] |
Prospective Interpretation -- The compensation-design implications Two unsettled interpretive issues. (i) Treatment of the rupees twelve lakh threshold and the rupees seventy-five thousand standard deduction interaction -- the new-regime computation is rupees twelve lakh of total income plus rupees seventy-five thousand standard deduction = rupees twelve lakh seventy-five thousand of pre-deduction income produces zero tax. The compensation-design implication is that any negotiation should target either rupees twelve lakh seventy-five thousand (zero tax) or accept the standard taper above. (ii) Treatment of the marginal-relief band -- between rupees twelve lakh and approximately rupees twelve lakh seventy-eight thousand of total income, the marginal relief mechanism prevents tax exceeding the differential between income and rupees twelve lakh. The Tribunal jurisprudence on the precise marginal-relief computation is sparse; the BharatTax case-law database should monitor emerging Tribunal positions.
