A common misconception in income tax planning is that an Association of Persons (AOP) or Body of Individuals (BOI) is always taxed at standard individual slab rates. In reality, the taxation framework is a tiered mechanism governed by entity-level disallowance rules, profit-sharing determinacy, and the personal income levels of individual members.

Before calculating entity tax liability, business profits must be adjusted by adding back disallowed payments made to members:

• Remuneration Rule: Any salary, bonus, commission, or remuneration paid to a member is strictly disallowed in all circumstances.
• Net Interest Rule: If an AOP pays interest to a member but also receives interest from that same member, only the net interest paid is disallowed.
• Capacity Matters: Deductibility depends on the capacity in which the member is acting within the entity versus the capacity in which interest is received/paid.

Whether an AOP/BOI enjoys slab rates or is taxed at the Maximum Marginal Rate (MMR) depends on member share determinacy and their personal income levels:

Scenario A: Member Shares are Unknown / Indeterminate

• The entire income of the AOP/BOI is taxed at MMR.
• If any member is taxable at a rate higher than MMR (e.g., a foreign company), the entire entity income is taxed at that higher rate.

Scenario B: Member Shares are Known / Determinate

Case 1: All members' Net Taxable Income (NTI) ≤ Basic Exemption Limit (BEL): The AOP is taxed at normal individual slab rates.

Case 2: One or more members' NTI > Basic Exemption Limit (BEL): The entire income of the AOP is taxed at MMR.

Case 3: Any member is taxable at a rate higher than MMR: That specific member's share is taxed at the higher rate, while the balance income is taxed at MMR.

To compute individual taxable income and avoid double taxation:

Step 1: Calculate Net Taxable Income of AOP/BOI by adding back disallowed remuneration, interest u/s 35(f), and cash expense disallowances.

Step 2: Deduct actual remuneration and interest paid to members to find the divisible balance profit.

Step 3: Apportion divisible balance profit among members as per Profit Sharing Ratio (PSR).

Step 4: Gross Member Share = Individual Remuneration + Individual Interest + Apportioned Profit Share − Interest on borrowed capital used for investment in AOP.

Tax Impact on Member Personal Assessment

• AOP Taxed at MMR: When AOP paid tax at MMR or Higher Rate: The allocated share is fully exempt in the member's hands. It is not included in total income even for rate purposes.
• AOP Taxed at Slab Rates: When AOP paid tax at Slab Rates: The share is included in the member's total income for rate purposes, and a proportionate rebate is granted u/s 310.

Scenario Overview: Base Data for XYZ (AOP/BOI):

• Net Profit as per P&L: ₹4,30,000 | Cash Expense Disallowance: ₹60,000
• Mr. A (40%): Interest ₹40,000, Remuneration ₹1,60,000
• Mr. B (30%): Interest ₹40,000, Remuneration ₹1,40,000
• Mr. C (30%): Interest ₹10,000, Remuneration ₹1,00,000
• Regime: All parties opted out of default regime to Optional/Old Regime (Basic Exemption Limit = ₹2,50,000).

Entity-Level Income Computation (Common to Both Cases)

Member Share Apportionment u/s 309

Divisible Balance Profit = ₹9,80,000 − ₹4,00,000 − ₹90,000 = ₹4,90,000

Case 1: Member Other Income ≤ Basic Exemption Limit (Taxed at Slab Rates)

Other Incomes: Mr. A = ₹1,60,000 | Mr. B = ₹2,40,000 | Mr. C = ₹2,20,000 (All ≤ ₹2,50,000 BEL).

• Tax on AOP: Normal slab rates apply. Basic Tax = ₹1,08,500. Cess @ 4% = ₹4,340. Total Tax Payable = ₹1,12,840.
• Mr. A: Total Income = ₹5,56,000. Tax (incl. Cess) = ₹24,648. Rebate u/s 310 = (₹24,648 × ₹3,96,000 / ₹5,56,000) = ₹17,555. Net Tax Payable = ₹7,090.
• Mr. B: Total Income = ₹5,67,000. Tax (incl. Cess) = ₹26,936. Rebate u/s 310 = (₹26,936 × ₹3,27,000 / ₹5,67,000) = ₹15,535. Net Tax Payable = ₹11,400.
• Mr. C: Total Income = ₹4,77,000. Tax = ₹11,350. Less: Rebate u/s 87A = ₹11,350. Net Tax Payable = ₹Nil.

Case 2: One or More Members' Other Income > Basic Exemption Limit (Taxed at MMR)

Condition: One or more members have personal taxable income exceeding ₹2,50,000.

• Tax on AOP: The entire entity income is taxed at MMR (42.744%). Tax = ₹9,80,000 × 42.744% = ₹4,18,890.
• Member Tax Impact: Allocated shares (Mr. A: ₹3,96,000, Mr. B: ₹3,27,000, Mr. C: ₹2,57,000) are fully exempt in their personal hands. No addition to total income, no rebate u/s 310 needed. Members pay tax strictly on personal other income at slab rates.

Assessment proceeds as if no dissolution or discontinuance occurred.

• Joint & Several Liability: Every person who was a member at the time of dissolution, along with legal representatives of deceased members, remains jointly and severally liable for all taxes, interest, and penalties across all tax years since the formation of the AOP.
