Determination of Income of AOP

Association of Persons (AOP) and Body of Individuals (BOI) are common forms for joint ventures, consortia and informal pooled arrangements in India. The Income-tax Act treats them as separate taxable entities, with their own assessment, but the manner of taxation depends critically on how the shares of members are determined. For FY 2026-27, the principles of Sections 67A, 86, 167B and the related rate provisions continue to govern AOP taxation alongside the new tax regime architecture refreshed by the Union Budget 2026.

What Is an AOP and When Does It Arise

An Association of Persons exists when two or more persons join together with a common purpose to earn income. Unlike a partnership firm registered under the Indian Partnership Act, an AOP does not require formal documentation, although a written agreement is recommended. AOPs commonly emerge in real-estate joint developments, infrastructure consortia, EPC sub-contracts, and pooled investment arrangements.

Computing Total Income of an AOP

1. Compute income under the five heads — salary (typically not applicable), house property, business or profession, capital gains and other sources.
2. Allow deductions under Chapter VI-A wherever permissible to the AOP.
3. Deductions specific to partners (like salary, interest on capital) are governed by Section 40(ba), which generally disallows such payments to members of an AOP.
4. Arrive at gross total income, set off losses, and compute total income chargeable to tax.

Tax Rates Applicable to AOPs

AOP tax rates depend on two factors — whether the individual shares of members are determinate and known, and whether any member has total income exceeding the basic exemption limit. The broad rules under Section 167B are:

• Where shares of members are indeterminate or unknown — the AOP is taxed at the maximum marginal rate on the entire income.
• Where shares are determinate but any member has total income above the basic exemption limit — maximum marginal rate applies to the entire income.
• Where shares are determinate and no member's individual income exceeds the basic exemption limit — slab rates applicable to individuals apply to the AOP.
• Where any member is itself taxed at a rate higher than the maximum marginal rate (rare), that higher rate applies on the portion of income attributable to such member.

Treatment in the Hands of Members

Section 86 explains how the share of a member in the income of the AOP is taxed in the member's own hands. The key rules are:

• If the AOP is taxed at the maximum marginal rate or at a higher rate, the member's share is not included in the member's total income; only a notional inclusion for rate purposes may occur.
• If the AOP is taxed at slab rates, the share of the member is included in the member's total income with a rebate of tax already paid by the AOP, computed in the prescribed manner.
• If the AOP is not chargeable to tax, the share is fully taxable in the hands of the member at the member's applicable rate.

Important Compliance Points

1. Obtain a separate PAN for the AOP.
2. Maintain books of account as required under Section 44AA if turnover thresholds are crossed.
3. Get accounts audited under Section 44AB where applicable.
4. File the Income-tax Return in Form ITR-5 within the due date under Section 139(1).
5. Apportion income to members based on the agreed sharing ratio for inclusion or rebate computation.

Common Issues in AOP Taxation

The most frequent disputes concern whether a particular arrangement is an AOP at all (versus a joint venture company, partnership firm or principal-agent relationship), determinacy of member shares, and characterisation of payments to members as salary, interest or share of profits. The Supreme Court in CIT v Indira Balkrishna and several later decisions has clarified the tests but each AOP must be evaluated on its own contractual fabric.

Conclusion

AOPs offer a flexible vehicle for joint commercial undertakings but bring a distinctive tax architecture. For FY 2026-27, ensure that the member-sharing ratio is documented and determinate, file the AOP return on time, and reconcile member-level inclusions and rebates carefully. Sound documentation at the formation stage prevents both maximum-marginal-rate exposure and disputes between members.
