Determination of Income of AOP

Determination of Income of AOP

An Association of Persons (AOP) is taxed as a separate entity under the Income-tax Act, 1961, but the rate — individual slabs or maximum marginal — turns on two questions: are members' shares determinate, and does any member's own income exceed the basic exemption limit? For FY 2026-27 (AY 2027-28), Section 167B governs that rate decision, Section 86 controls how each member handles their proportionate share, and Section 40(ba) absolutely disallows salary or interest paid to members. Get these three provisions right — in that order — and AOP taxation becomes tractable.

What Qualifies as an AOP — and What Does Not

An Association of Persons arises when two or more persons join together with a common purpose to produce income. The word "persons" is deliberately wide under Section 2(31): it includes individuals, companies, other AOPs, partnership firms, and even trusts. No registration or formal deed is required; the Act taxes the AOP based on functional reality, not on whatever label the parties choose.

AOPs most commonly appear in:

• Real-estate joint developments where a landowner contributes land and a builder contributes capital or construction expertise, sharing revenue or built-up area
• Infrastructure and EPC consortia formed to win and execute government tenders jointly
• Film production pooling, where co-producers share box-office receipts and streaming rights
• Pooled investment vehicles that lack the structure of a company or LLP

An AOP is not:

• A registered partnership firm under the Indian Partnership Act 1932 — firms are taxed under Sections 184–185 and Section 40(b) governs partner remuneration differently
• A company or LLP — both have independent charging sections under the Act
• A principal-agent arrangement — the agent earns income on behalf of the principal and there is no pooling of purpose

The Supreme Court in CIT v. Indira Balkrishna (1960) established the twin tests of common purpose and joining together. Later decisions confirmed that passive co-ownership — co-heirs simply holding inherited property without active cooperation — does not constitute an AOP.

Practical check before filing as an AOP: Examine the underlying agreement. If parties have merely co-invested and income arises without coordinated effort or joint management, the safer position is to assess each person individually on their proportionate share rather than constitute an AOP.

Step-by-Step: Computing Total Income of an AOP

AOP income is computed under the same five heads as an individual return, but several AOP-specific rules alter the numbers materially.

Step 1 — Identify Income Under Each Head

1. Salaries — Rarely arises for an AOP as a recipient, but possible where the AOP itself is the contractual employer.
2. Income from house property — Apply Sections 22–25 in the standard way; the 30% standard deduction on NAV is available.
3. Profits and gains from business or profession — The dominant head for most AOPs. Apply Sections 28–44DB. This is also where Section 40(ba) bites hardest.
4. Capital gains — Apply Sections 45–55A. In joint development agreements, the landowner-AOP may recognise capital gains at the point of transfer of development rights.
5. Income from other sources — Apply Section 56 for interest income, dividend income, and other receipts not chargeable under the first four heads.

Step 2 — Apply Section 40(ba): Disallow All Payments to Members

This is the single most consequential AOP-specific rule and the one most frequently overlooked. Section 40(ba) disallows, in computing AOP business income, any payment of:

• Interest on capital or loans to a member
• Salary, bonus, commission, or remuneration of any kind to a member

The disallowance is absolute and unconditional. Unlike Section 40(b) for partnership firms, there is no provision allowing a deduction up to a specified ceiling. Whatever the AOP pays a member as salary or interest is added back in full before computing taxable income.

Why this traps people in practice: An AOP that labels a member's compensation as a "management fee," "consultancy charge," or "service fee" may still face disallowance under Section 40(ba) if the Assessing Officer concludes the payment is effectively a share of profits or member remuneration. The nature of the payment governs, not the invoice description.

Step 3 — Claim Permissible Chapter VI-A Deductions

Deductions under Sections 80C to 80U are available to the AOP to the extent they relate to the AOP's own expenditure. Deductions that are inherently personal in nature — such as Section 80C (life insurance, PPF) — are generally not available. Section 80G (eligible charitable donations) and Section 80GGB (political contributions) can apply depending on the AOP's activities. Verify each deduction against the explicit language of the section.

Step 4 — Set Off and Carry Forward of Losses

Business losses of the AOP can be set off against other business income of the AOP in the same year. Unabsorbed business losses carry forward for eight assessment years under Section 72, but only if the AOP filed its return by the due date. Missing the ITR-5 due date extinguishes this right under Section 80. Capital losses follow Sections 74 and 74A; speculative losses follow Section 73.

Step 5 — Arrive at Total Income

After deductions and set-offs, you reach the AOP's total income chargeable to tax. This figure feeds directly into the Section 167B rate analysis below.

Section 167B: The Rate Decision Tree

Section 167B is the engine that determines whether the AOP pays at slab rates or the maximum marginal rate (MMR). Work through the branches sequentially.

Branch 1 — Shares Indeterminate or Unknown

If the profit-sharing ratios of members cannot be determined from the agreement or surrounding evidence, the AOP is taxed at the maximum marginal rate on its entire income. No slab benefit, no basic exemption. This is the harshest outcome — and entirely avoidable through documentation.

Maximum marginal rate is defined under Section 2(29C) as the rate applicable to the highest income slab for an individual under the Finance Act of the relevant year, inclusive of the applicable surcharge and health and education cess of 4%. For FY 2026-27, apply the Finance Act 2026 rate schedule as notified to determine the precise MMR figure.

Branch 2 — Shares Determinate, But One Member's Total Income Exceeds the Basic Exemption Limit

If shares are determinate but any single member's total income — including that member's proportionate share of AOP income — exceeds the basic exemption limit, the AOP is taxed at the MMR on its entire income. The logic is anti-avoidance: high-income individuals should not be able to route earnings through an AOP to access lower slab rates.

Critical point: you must compute each member's total income (their own independent income plus their AOP share) to run this test. It is not enough to look at the AOP income alone.

Branch 3 — Shares Determinate and No Member Exceeds the Basic Exemption Limit

Only when both conditions hold — shares are documented and every member's total income stays within the basic exemption limit — does the AOP enjoy taxation at individual slab rates. In practice this applies mainly to small informal poolings where all members have modest incomes.

Branch 4 — A Member Is Subject to a Rate Higher Than the MMR

Where any member (for example, a foreign corporate entity) is liable to tax at a rate exceeding the MMR, the share of AOP income attributable to that member is taxed at that higher applicable rate. This branch is uncommon but relevant in joint ventures where one leg is a non-resident company subject to a treaty-overridden or Section 115A rate.

Section 86: What Members Do With Their Share

Once the AOP has paid its own tax, Section 86 governs what each member does in their individual return.

If the AOP Paid Tax at MMR (Branches 1 or 2)

The member's share of AOP income is excluded from the member's total income for computation of tax. The member does not pay tax on that share again. However, under the rate inclusion rule, the excluded share is added to the member's other income solely to determine the rate at which the member's remaining income is taxed. This prevents a wealthy individual from benefiting from lower rates on their personal income merely because the AOP absorbed the tax on their AOP share.

If the AOP Paid Tax at Slab Rates (Branch 3)

The member includes the proportionate share of AOP income in their own total income. To prevent double taxation, the member claims a rebate equal to the tax already paid by the AOP on that share at the AOP's average rate. The average rate of the AOP is: total tax paid by the AOP ÷ total income of the AOP. The rebate is capped at the lower of the tax at the AOP's average rate and the tax at the member's own average rate on that share.

If the AOP Has No Tax Liability

Where the AOP itself falls below the tax threshold, the share of each member is fully taxable in the member's hands at their own applicable rate.

Section 67A: Head-Wise Apportionment of AOP Income

Section 67A provides the arithmetic for splitting AOP income among members. The key rule is that income must be apportioned head-wise, not just in aggregate. Each member's share retains the character it had in the AOP's hands.

This matters because:

• A long-term capital gain in the AOP remains a long-term capital gain in the member's hands and attracts the applicable capital gains rate — not the member's slab rate.
• Business income retains business income character.
• A member cannot re-characterise their AOP share to access a preferential rate that the AOP itself was not entitled to.

Worked Example: Sections 167B, 67A, and 86 in Practice

Scenario: Sunrise Infrastructure AOP has three members — A (individual), B (individual), and C (a private limited company). Profit-sharing ratio: 40 : 40 : 20. The AOP's total income for FY 2026-27 comprises business income of Rs. 18,00,000 and long-term capital gains of Rs. 12,00,000, totalling Rs. 30,00,000.

Head-wise income allocation under Section 67A:

Step 1 — Run the Section 167B Branch Test:

• Are shares determinate? Yes — 40:40:20 is documented in the formation agreement.
• Does A's total income exceed the basic exemption? A has Rs. 80,000 from a fixed deposit outside the AOP. A's total income = Rs. 12,00,000 (AOP share) + Rs. 80,000 = Rs. 12,80,000. Yes — exceeds the basic exemption limit.

Branch 2 applies. The AOP is taxed at the MMR on its entire income of Rs. 30,00,000.

Step 2 — Tax computation at AOP level:

Tax = Rs. 30,00,000 × MMR (as per Finance Act 2026 rates). At the illustrative MMR of 35.88% (30% base + 15% surcharge + 4% cess, applicable where AOP income exceeds Rs. 1 crore — verify the exact rate from the Finance Act 2026 notification):

Tax payable by AOP ≈ Rs. 10,76,400 (illustrative — apply notified rate)

Step 3 — Member A's treatment in ITR-3 (individual, business income present):

• A's AOP share of Rs. 12,00,000 is excluded from A's total income.
• A's total income for rate purposes = Rs. 12,00,000 + Rs. 80,000 = Rs. 12,80,000.
• A pays tax on Rs. 80,000 at the rate applicable to Rs. 12,80,000 (rate inclusion effect under Section 86).
• A does not pay tax a second time on the Rs. 12,00,000.

What if only B had triggered the MMR and A's total income was within the exemption limit? The outcome is the same — even one member crossing the threshold triggers Branch 2 for the entire AOP. The AOP still pays MMR on all Rs. 30,00,000.

Late filing scenario: If Sunrise Infrastructure AOP misses the 31 October 2027 audit deadline and files on 15 January 2028, it pays Rs. 10,000 in late fees under Section 234F. More damagingly, it loses the right to carry forward any business losses under Section 80 — even if the current year shows a profit and prior-year losses could have been utilised.

Common Mistakes and How to Fix Them

Mistake 1 — Filing as Individual Co-Owners Rather Than as an AOP

Many joint-venture promoters assume that because they are just "co-owners," each person can declare their share individually without ever filing an AOP return. If the arrangement involves joint management, joint decision-making, and a common pool of income, the AO can raise an AOP assessment separately — with interest under Sections 234A/234B/234C and potential penalty under Section 270A for under-reporting.

Fix: If two or more persons actively cooperate to earn income from a joint project, obtain a separate PAN for the AOP and file ITR-5 even if the income is modest.

Mistake 2 — Failing to Obtain a Separate PAN for the AOP

AOP PAN applications are filed in Form 49A on the Protean (NSDL) portal. Required documents include the formation agreement or deed, identity and address proof of the principal officer, and a resolution authorising the principal officer to apply. Without a PAN, every payment received by the AOP attracts TDS at the higher rate under Section 206AA, which can significantly impair cash flows.

Mistake 3 — Deducting Member Salary or Interest and Expecting It to Survive Scrutiny

Section 40(ba) is an absolute bar. Firms sometimes mimic partnership firm practices and pay a member a salary or interest on capital, deducting it in the AOP's books. On scrutiny, the AO disallows the deduction in full, recalculates taxable income, raises a demand, and charges interest under Section 220(2) on the unpaid demand.

Fix: Remove member salary and interest lines entirely from the AOP's profit and loss statement. Make all payments to members as profit distributions in the documented sharing ratio.

Mistake 4 — Applying Section 115BAC (New Tax Regime) to an AOP

Section 115BAC, as amended to become the default regime for FY 2024-25 onwards, applies only to individuals and HUFs. AOPs are outside its scope. Filing an AOP's return using the new-regime slab schedule constitutes an incorrect return and may attract defective-return proceedings under Section 139(9).

Fix: Always apply the regular old-regime provisions and Section 167B to an AOP. There is no opt-in to the new regime for AOP.

Mistake 5 — Missing the ITR-5 Due Date

The Income-tax return for an AOP is filed in Form ITR-5 on the e-filing portal at incometax.gov.in. Due dates for AY 2027-28 (FY 2026-27):

• 31 July 2027 — where no audit is required under Section 44AB
• 31 October 2027 — where a tax audit is required
• 30 November 2027 — where a transfer-pricing report under Section 92E is also required

Late-filing fees under Section 234F:

Beyond the fee, filing after the original due date means the AOP forfeits the right to carry forward business losses and certain other losses under Section 80.

Mistake 6 — Inconsistency Between AOP Return and Member Returns

If the AOP's ITR-5 discloses total income of Rs. 30,00,000 but members' returns either include the AOP share at slab rates (when MMR applied) or omit it entirely (when slab rates applied and inclusion was required), the AIS/TIS (Annual Information Statement/Taxpayer Information Summary) mismatch flags both the AOP and individual members for scrutiny.

Fix: After finalising the AOP return, prepare a member-level reconciliation workings sheet before filing each member's individual return. Confirm whether Section 86 exclusion or inclusion with rebate applies, and carry the same numbers into the ITR consistently.

ITR-5 Filing Checklist for AY 2027-28

• [ ] AOP PAN obtained via Form 49A on the Protean portal
• [ ] Books of account maintained under Section 44AA (mandatory where AOP carries on business/profession above the turnover threshold)

• [ ] Total income computed under all five heads with Section 40(ba) add-backs applied
• [ ] Section 167B branch test documented: shares determinate? Each member's total income computed and compared to basic exemption limit?
• [ ] Tax computed at applicable rate (slab or MMR) with advance tax tracked and interest under Sections 234B/234C calculated if advance tax was deficient
• [ ] Head-wise apportionment of income to members prepared under Section 67A

• [ ] ITR-5 JSON generated and uploaded on incometax.gov.in before the applicable due date
• [ ] ITR-V acknowledgement downloaded and archived

Key Takeaways

• Document profit-sharing ratios in writing before the first rupee of income arises. Indeterminate shares trigger the maximum marginal rate under Section 167B with no remedy after the fact — the cost can equal the entire tax-slab advantage you hoped to preserve.
• Section 40(ba) disallows member salary and interest absolutely. Unlike partnership firms under Section 40(b), there is no permissible ceiling. Deducting member remuneration simply creates a guaranteed adjustment demand on scrutiny.
• Run the Section 167B test sequentially. Check indeterminacy first; then test whether any one member's total income (own income plus AOP share) exceeds the basic exemption. Only if both tests are clear do slab rates apply to the AOP.
• Section 115BAC does not apply to AOPs. The new tax regime is exclusively for individuals and HUFs. Apply the old-regime rate schedule and Section 167B throughout when computing AOP tax.
• Head-wise apportionment under Section 67A preserves the character of income. Long-term capital gains in the AOP remain long-term capital gains in the member's hands — the member cannot re-characterise that income.
• File ITR-5 before the due date — the stakes extend beyond late fees. Belated filing extinguishes the right to carry forward business losses under Section 80, a loss that compounding future profits cannot recover.
• Reconcile the AOP return with every member's individual return before filing either one. AIS/TIS matching is now automated; discrepancies surface quickly and consume disproportionate compliance effort to resolve.
