Section 87A Rebate and Agricultural Income Under Partial Integration: A Pre-Filing Analysis for AY 2026-27

Overview: Why This Issue Demands Attention Now

A specific category of assessees is heading into AY 2026-27 with a tax planning question that remains unanswered — not because the statute is ambiguous, but because the ITR filing utilities have not yet been released and history suggests that when they are, the programmed logic may not align with what the law actually says.

The core issue: an individual resident assessee operating under the new tax regime (Section 115BAC) has non-agricultural taxable income below ₹12,00,000 — making the assessee eligible for the rebate under Section 87A on a plain reading of the law. However, the same assessee also earns substantial agricultural income, which triggers the partial integration mechanism under the Finance Act 2025 rate schedule. The question is whether the partial integration arithmetic — which temporarily adds agricultural income to compute the correct marginal rate — affects the assessee's eligibility for the Section 87A rebate.

This is not an academic exercise. The AY 2026-27 ITR utilities, validation schemas, and filing rules are yet to be published. That window — right now — is precisely the moment for practitioners to examine the statutory position, document their analysis, and advise clients on both possible outcomes before any regime choice is finalised.

Understanding What Section 87A Actually Provides

Section 87A of the Income Tax Act 1961, as amended by the Finance Act 2025 and applicable from AY 2026-27, reads:

"An assessee, being an individual resident in India, whose total income does not exceed twelve lakh rupees shall be entitled to a deduction from the amount of income-tax (as computed before allowing for the deductions under this Chapter) on his total income…"

Two elements of this provision carry critical weight:

• The eligibility threshold is measured against total income
• The rebate itself is applied against tax computed on total income

Nowhere in the provision does the language reference "total income as adjusted for partial integration purposes" or "total income as augmented by agricultural income for rate computation." The statutory reference is unambiguously to total income as defined under the Act.

The Role of Section 10(1): A Mandatory Exclusion, Not a Post-Computation Deduction

Section 10 of the Income Tax Act 1961 begins with the following words:

"In computing the total income of a previous year of any person, any income falling within any of the following clauses shall not be included — (1) agricultural income"

This is a point of computation, not a relief granted after total income is determined. Agricultural income does not enter the computation of total income at all. It is excluded at the source of the calculation itself.

Section 2(45) defines total income as "the total amount of income referred to in Section 5, computed in the manner laid down in this Act." The manner laid down in the Act includes Section 10(1), which removes agricultural income from the calculation entirely. Therefore:

• An assessee with ₹11,90,000 of non-agricultural taxable income and ₹16,00,000 of agricultural income has a total income of ₹11,90,000 — not ₹27,90,000.
• The phrase "shall not be included" in Section 10 is a mandatory exclusion, not a discretionary relief or exemption.
• Agricultural income never features in the total income figure — and it is that figure which governs Section 87A eligibility.

The Partial Integration Mechanism: A Rate-Finding Tool, Not a Redefinition of Total Income

The partial integration method does not appear anywhere in the Income Tax Act 1961 itself. It is embedded in the proviso to the rate schedule contained in the Finance Act — for FY 2025-26, the Finance Act 2025. The methodology operates as follows:
