Assessment of Association of Persons and Body of Individuals (CA Final DT)

Updated 5 October 2026 · Fact-checked

An AOP or BOI is taxed as a separate person on its total income. If members' shares are indeterminate or unknown, tax is at the maximum marginal rate. If shares are determinate, slab rates apply, unless a member has other income above the basic exemption limit, which brings in the maximum marginal rate. Members get relief from double tax on their shares.

Understand Assessment of Association of Persons and Body of Individuals

An Association of Persons (AOP) is a group of persons, who may be individuals, companies, firms or others, that join together by their own will for a common purpose, usually to earn income. A Body of Individuals (BOI) is a group made up only of individuals, such as co-heirs who carry on an inherited business together. Both are 'persons' in their own right, so the AOP or BOI itself is assessed on its total income.

The tax rate depends on one question: are the members' shares in the income determinate and known? Shares are determinate when the instrument, agreement or the facts fix each member's share, for example 50:50. They are indeterminate when the shares are not fixed, or the managers can vary them at will.

If shares are indeterminate or unknown, the AOP is taxed at the maximum marginal rate (MMR). This is the highest rate in the slab structure for an individual, with surcharge and cess as applicable. If the tax on the AOP's income at normal slab rates would be higher, that higher tax applies. Since no slab rate exceeds the MMR, this check rarely changes the answer. If shares are determinate, the AOP is taxed at slab rates. However, if any member's total income, excluding his share from the AOP, exceeds the basic exemption limit applicable to him, the AOP is taxed at the MMR. The law is designed so that an AOP cannot be used to split income and cut tax.

To avoid double taxation, the member's share in the AOP's income is dealt with as follows:

Where the AOP is taxed at normal slab rates, the share is exempt in the member's hands.
Where the AOP is taxed at the MMR, the share is exempt only to the extent it relates to income taxed at a rate not exceeding the rate applicable to the member. The excess share is included in the member's total income, and he gets a rebate for the tax the AOP has already paid on it.

In every case, the AOP's own tax is computed first.

Computing the AOP's income follows the usual heads. One point matters: interest, salary, bonus, commission or remuneration paid by an AOP or BOI to its members is not deductible. It is an application or appropriation of profit, not an expense incurred to earn it. So if the books have charged it, add it back. The provisions that restrict such payments in the case of firms apply only to firms. They do not govern an AOP or BOI, so do not carry the firm rules over. Other business expenses follow the normal rules.

Key rules to remember

Indeterminate or unknown shares: Tax = total income of AOP × MMR (or tax at normal slab rates, if higher) + surcharge, if any + 4% cess; MMR means the highest slab rate for an individual, i.e. 30%. Add surcharge and cess as applicable.
Determinate shares, no member with other income above the exemption limit: Tax = tax on total income of AOP at normal slab rates + surcharge, if any + 4% cess; Test each member's total income excluding his share from the AOP, against his own basic exemption limit.
Determinate shares, any member above the exemption limit: Tax = total income of AOP × MMR + surcharge, if any + 4% cess; One such member is enough to trigger MMR on the whole income of the AOP.
Member's share where AOP is taxed at slab rates: Share of member in AOP income = exempt in member's hands; This avoids double tax. It applies only to the share on which the AOP has paid tax.
Member's share where AOP is taxed at MMR: Exempt share = part of share relating to income taxed at a rate not exceeding the member's applicable rate; excess share = included in member's total income, with rebate; The member's applicable rate decides how much of the share is exempt. The excess is taxed in his hands, and he gets a rebate for the tax paid by the AOP on it.
Payments to members: Interest, salary, bonus, commission or remuneration paid by AOP/BOI to a member = not deductible (appropriation of profit); add back if charged in the books; The firm provisions that restrict such payments apply only to firms. They do not apply to an AOP or BOI.

How to solve Assessment of Association of Persons and Body of Individuals questions

Use this order for any AOP/BOI assessment question. The rate decision comes before the arithmetic.

1Confirm that the entity is an AOP or BOI. Look for voluntary joint action for a common purpose, or a group of individuals only for a BOI.
2Compute the AOP's total income under the normal heads. Add back interest, salary, bonus, commission or remuneration paid to members that the books have deducted, because these are an appropriation of profit. Do not apply the firm provisions.
3Check whether members' shares are determinate and known. If they are indeterminate or unknown, go to step 5.
4If shares are determinate, find each member's total income excluding his share from the AOP. Compare it with his basic exemption limit.
5Choose the rate: MMR if shares are indeterminate, or if any member is above the exemption limit. Otherwise use slab rates. For indeterminate shares, the tax is the MMR tax unless slab-rate tax would be higher.
6Compute tax on the AOP's total income. Apply any special-rate income at its own rate, then add surcharge, if applicable, and 4% cess.
7Deal with members' shares. If the AOP paid tax at slab rates, the share is exempt. If it paid at MMR, the share is exempt only to the extent taxed at a rate not exceeding the member's applicable rate. Include the excess in his total income and allow the rebate.
8Write the conclusion in the form: provision, facts, conclusion.

Quickest way: Two-question rate check

When to use it: Use in MCQs and short descriptive questions where you only need the rate or the tax figure.

Ask: are shares indeterminate or unknown? If yes, write MMR and stop.
If shares are determinate, scan for any member whose other income is above his exemption limit. If found, write MMR.
If no member is above the limit, use slab rates.
Finish with the member's share. At slab rates, it is exempt. At MMR, it is exempt only up to the member's applicable rate, and the excess is taxed in his hands with a rebate.

Common mistakes in Assessment of Association of Persons and Body of Individuals

Applying slab rates whenever shares are given as a ratio.
Students stop after seeing that shares are determinate and forget the second test on members' other income.
Fix: Always check each member's other income against his basic exemption limit before choosing slab rates.
Allowing interest, salary or other remuneration paid to members as a deduction for an AOP or BOI, or applying the firm provisions to them.
It looks like a normal business expense, and students mix it up with the separate rules for firms.
Fix: For an AOP/BOI, such payments to members are an appropriation of profit and are not deductible, so add back any amount charged in the books. The firm provisions cover firms only and do not apply to an AOP or BOI.
Excluding the member's share in full whenever the AOP paid tax at MMR.
Students remember 'no double tax' and stop there.
Fix: At MMR, the share is exempt only to the extent taxed at a rate not exceeding the member's applicable rate. Include the excess in his total income and allow the rebate.
Including the member's share in the exemption-limit test.
Students use the member's total income including the AOP share.
Fix: The test uses the member's total income excluding his share from the AOP.
Treating AOP and BOI as having different tax rates.
The two terms are defined differently, so students assume different treatment.
Fix: The difference is in membership: a BOI has only individuals, while an AOP can include any persons. The rate rules are the same for both.
Forgetting surcharge and cess when the question gives a large income.
Students stop at the 30% MMR.
Fix: Read the question for the instruction on surcharge and cess. Add 4% cess always, and surcharge only where income crosses its thresholds.

Worked examples

Example 1

Ravi, Sohan and Tara are co-heirs who run a hotel inherited from their father. The deed does not fix their shares, and the manager decides each year how to split profit. Total income of the BOI for the tax year is ₹12,00,000. Compute the tax liability of the BOI.

Show the solution

Provision: if the shares of members are indeterminate or unknown, the BOI is taxed at the maximum marginal rate, or at slab rates if that tax would be higher.
Facts: the heirs have no fixed shares, so shares are indeterminate.
MMR is 30%. Tax = ₹12,00,000 × 30% = ₹3,60,000.
No slab rate is above 30%, so slab-rate tax on ₹12,00,000 cannot exceed ₹3,60,000. The MMR tax is the higher amount and applies. Surcharge does not apply because income is below ₹50 lakh.
Cess = 4% × ₹3,60,000 = ₹14,400.
Total tax = ₹3,60,000 + ₹14,400 = ₹3,74,400.
Members' shares: the BOI has paid tax at MMR. Each member's share is exempt only to the extent taxed at a rate not exceeding the member's applicable rate. Any excess is included in his total income, with a rebate for the tax the BOI paid on it.

Answer: Tax payable by the BOI is ₹3,74,400. Members' shares are exempt only up to their applicable rates; the excess is taxed in their hands with a rebate.

Example 2

Anil and Bina form an AOP to run a printing unit. Their profit-sharing ratio is fixed at 50:50 by a written agreement. The AOP's total income is ₹6,00,000. Anil has other income of ₹8,00,000 from salary and house property, which is above his basic exemption limit. Bina has no other income. Assume both members are taxed under the old regime slabs: nil up to ₹2,50,000, 5% from ₹2,50,000 to ₹5,00,000, 20% from ₹5,00,000 to ₹10,00,000 and 30% above ₹10,00,000. Compute the tax of the AOP and state the treatment of the share received by Anil and by Bina.

Show the solution

Provision: if shares are determinate, slab rates apply, unless any member's total income, excluding his share from the AOP, exceeds his basic exemption limit. In that case, MMR applies.
Facts: shares are determinate at 50:50. Anil's other income of ₹8,00,000 is above his exemption limit. Bina's is not.
One member above the limit is enough, so MMR applies to the whole income of the AOP.
Tax = ₹6,00,000 × 30% = ₹1,80,000.
Cess = 4% × ₹1,80,000 = ₹7,200.
Total tax = ₹1,80,000 + ₹7,200 = ₹1,87,200.
Members' shares: each member's share is ₹3,00,000, and the AOP has borne tax on it at 30%. A share is exempt only to the extent it relates to income taxed at a rate not exceeding the member's applicable rate.
Anil: his income without the share is ₹8,00,000. Adding the share takes it to ₹11,00,000. The first ₹2,00,000 of the share (₹8,00,000 to ₹10,00,000) falls in his 20% slab. The remaining ₹1,00,000 (₹10,00,000 to ₹11,00,000) falls in his 30% slab.
Anil, 30% band: the AOP rate of 30% does not exceed his rate of 30%, so ₹1,00,000 is exempt.
Anil, 20% band: the AOP rate of 30% exceeds his rate of 20%, so ₹2,00,000 is the excess. It is included in his total income, which becomes ₹10,00,000. He gets a rebate for the tax the AOP paid on it (30% × ₹2,00,000 = ₹60,000 before cess).
Bina: her income without the share is nil. With the share her income is ₹3,00,000, which falls in her nil band (₹2,50,000) and 5% band (₹50,000). The AOP rate of 30% exceeds her rate in both bands, so none of the share is exempt.
Bina: the whole ₹3,00,000 is included in her total income, and she gets a rebate for the tax the AOP paid on it (30% × ₹3,00,000 = ₹90,000 before cess).

Answer: The AOP pays ₹1,87,200 at MMR. Of Anil's ₹3,00,000 share, ₹1,00,000 is exempt and ₹2,00,000 is included in his total income, with a rebate. Bina's entire ₹3,00,000 share is included in her total income, with a rebate.

Exam tips

Write the provision before the number. The two-step test of determinate shares and members' other income is where the marks are.
In case-scenario MCQs, read each member's income carefully. A member's salary or rental income is often hidden in the facts and decides the rate.
Always add back interest, salary and remuneration paid to members of an AOP/BOI, and show it as a separate line. Give the reason: it is an appropriation of profit. Do not quote the firm provisions for an AOP/BOI.
State the treatment of the members' share in one or two sentences at the end of the answer. Separate slab-rate and MMR cases. Examiners often give a separate mark for it.
If asked to differentiate AOP from BOI, give two points: who can be members, and the need for a common purpose or intention. Then say the tax rate rules are the same.

Practice questions from Assessment of Various Entities

Assessment of Association of Persons and Body of Individuals: frequently asked questions

What is the difference between AOP and BOI for income tax?

An AOP is formed when persons of any kind, such as individuals, firms or companies, come together voluntarily for a common purpose. A BOI consists only of individuals, and co-heirs are a common example. Both are taxed as separate persons under the same rate rules.

What is the maximum marginal rate for an AOP or BOI?

It is the highest rate in the slab structure for an individual, currently 30%, plus surcharge and cess as applicable. It applies when shares are indeterminate, or when shares are determinate but a member has other income above the basic exemption limit.

Is a member's share of AOP profit taxable in his hands?

It depends on how the AOP was taxed. If the AOP was taxed at slab rates, the share is exempt in the member's hands. If the AOP was taxed at MMR, the share is exempt only to the extent taxed at a rate not exceeding the member's applicable rate. The excess is included in his total income, with a rebate for the tax already paid by the AOP.

Can an AOP deduct interest or salary paid to its members?

No. Such payments to members are treated as an application or appropriation of profit, not as a business expense, so they are not deductible. Add them back if the accounts have debited them. The firm provisions that restrict such payments apply only to firms and do not govern an AOP or BOI.
