Indian Income Tax Law | Chapter VI-A Deductions
Section 80AB of the Income-tax Act, 1961: Deductions Based on Income Included in Gross Total Income
Section 80AB explains how the amount eligible for a deduction under Chapter VI-A, heading C, is calculated: the relevant income must first be computed under the Income-tax Act, before Chapter VI-A deductions, rather than simply using gross receipts or an amount shown in the accounts.
What does Section 80AB provide?
Section 80AB is a computation rule for deductions falling under Chapter VI-A, heading C: Deductions in respect of certain incomes. When the specified income is included in an assessee's gross total income, the deductible income is determined by computing that income in accordance with the Act, before making any Chapter VI-A deduction. The provision does not itself create a new deduction or override every eligibility condition or percentage limit of the section under which the deduction is claimed.
Section 80AB: statutory wording
Where any deduction is required to be made or allowed under any section included in this Chapter under the heading "C.- Deductions in respect of certain incomes" in respect of any income of the nature specified in that section which is included in the gross total income of the assessee, then, notwithstanding anything contained in that section, for the purpose of computing the deduction under that section, the amount of income of that nature as computed in accordance with the provisions of this Act (before making any deduction under this Chapter) shall alone be deemed to be the amount of income of that nature which is derived or received by the assessee and which is included in his gross total income.

Meaning of important expressions
Gross total income
Under Section 80B(5) of the 1961 Act, gross total income generally means total income computed under the Act before making deductions under Chapter VI-A. The calculation therefore follows the applicable income heads and set-off rules before eligible Chapter VI-A deductions are applied.
Income of the specified nature
This means the category of income to which the particular deduction provision under heading C applies. The eligible amount is not automatically the gross sale proceeds, turnover, dividend receipt or accounting profit: it is the amount determined under the relevant provisions of the Act.
Deduction and net eligible income
A deduction reduces the income chargeable to tax when statutory conditions are met. Section 80AB generally requires a deduction linked to specified income to be based on the statutorily computed amount of that income. Relevant allowable expenses and computation rules can affect that amount. The exact deduction rate and conditions come from the particular deduction section.
Example: gross receipts versus computed eligible income
| Illustrative particulars | Amount |
|---|---|
| Gross receipts from an activity potentially covered by a qualifying heading C provision | Rs. 12,00,000 |
| Expenses allowable under the relevant computation provisions (assumed) | Rs. 4,00,000 |
| Income of that nature computed under the Act before Chapter VI-A deductions | Rs. 8,00,000 |
In this simplified example, Rs. 8,00,000, not Rs. 12,00,000, is the starting amount for a deduction calculated by reference to that specified income. The amount actually deductible may be lower, or nil, because of the qualifying provision's conditions, any prescribed percentage, Section 80A limits, set-off rules and the applicable tax regime. This is an illustration of the method, not a claim that the activity itself qualifies.
Relationship with other provisions
- Section 80A: Provides the general Chapter VI-A framework, including the rule that aggregate deductions cannot exceed gross total income, and restrictions on overlapping claims.
- Section 80B(5): Defines gross total income for Chapter VI-A purposes.
- Heading C of Chapter VI-A: Contains deductions in respect of certain incomes. Section 80AB supplies the computation principle; the specific deduction section supplies eligibility, quantum and conditions.
- Section 80AC: May impose timely return-filing conditions on specified deductions for the relevant assessment year.
- Sections 80C and similar personal-investment deductions: These generally fall under a different heading of Chapter VI-A. Do not assume Section 80AB applies to every deduction numbered 80C to 80U.

Frequently asked questions
Does Section 80AB allow a deduction on gross receipts?
Not simply on gross receipts. It directs that the income of the specified nature be computed under the Act before Chapter VI-A deductions.
Is Section 80AB itself a separate deduction?
No. It determines the amount of qualifying income for a deduction provided elsewhere under heading C of Chapter VI-A.
Can a Chapter VI-A deduction exceed gross total income?
No. Section 80A(2) generally limits the aggregate Chapter VI-A deductions to the assessee's gross total income.
Does Section 80AB apply to Section 80C investments?
Section 80AB is directed to deductions under heading C, "Deductions in respect of certain incomes". Section 80C belongs to a different category of Chapter VI-A deductions.
