The deduction schedule needs a common control working
A qualifying payment or eligible business profit does not, by itself, establish the deduction ultimately allowable. Section 122 of the Income-tax Act, 2025 imposes common Chapter VIII controls, including the gross-total-income ceiling, restrictions on overlapping deductions, Part C filing conditions and market-value adjustments. This guide applies to tax year 2026–27, beginning 1 April 2026, using the Act as amended by Finance Act, 2026 and checked on 26 October 2026. It addresses the common computation layer; the underlying deduction section and applicable tax regime must independently permit each claim. Income Tax Department: section 122, 2026 text.
Start with computed income, not bank receipts
Under section 122(10), gross total income is total income computed under the Act before Chapter VIII deductions. It is not turnover, gross salary before all adjustments, the bank-credit total or the sum of positive income heads without the applicable loss rules. Reconcile the income computation and permitted set-offs first. Then apply each deduction’s own conditions, income exclusions, limits and regime restrictions. Section 122(2) places an outer ceiling on aggregate Chapter VIII deductions; it does not enlarge any individual deduction or authorise a deduction against specially protected income.
Keep Part C profit relief from being used twice
Section 122(4) addresses profits of an undertaking, unit, enterprise or eligible business claimed and allowed under Part C. To that extent, the same profits cannot support another deduction under the Act for that tax year, and the deduction cannot exceed the relevant profits. Build an overlap matrix identifying the actual profit component, claimant, section and amount allowed. Different labels on two schedules do not establish two separate income pools. Section 122(8) additionally bars section 46 relief for a specified business for the same or another tax year where Part C relief on that business’s profits is claimed and allowed.
Use the income computed under the Act
Section 122(9) requires a Part C income-based deduction to use income of the specified nature computed under the Act before Chapter VIII deductions. A gross royalty, service receipt or unit-sales figure is not automatically the deduction base. Identify deductible expenditure and other applicable computation adjustments before applying the relevant section’s deduction fraction or ceiling. This common rule supplies no universal deduction percentage.
Review transfers between businesses of the same assessee
Sections 122(6)–(7) require the eligible undertaking’s profits to be recomputed using market value when covered inter-business goods or services transfers are recorded at a different consideration. This can apply to transfers into or out of the eligible business. Establish the transfer date, quantity, open-market comparison and any regulatory price restriction. Where the transfer is a specified domestic transaction under section 164, the statutory definition instead invokes the arm’s-length price. Do not assume every internal transfer automatically triggers transfer-pricing documentation or use a journal balancing figure as market value.
Test the claimant and return conditions separately
Section 122(3) prevents a member from repeating the specified deduction in relation to an AOP/BOI share where that deduction is admissible to the association or body. Its listed sections are 133, 135, 137, 138, 141, 142 and 143. Separately, subsection (5) denies Part C relief if the assessee fails either to furnish the return by the section 263(1) due date or to claim the deduction in that return. Determine the actual applicable and validly extended due date; do not borrow a generic calendar date. This article does not assume that a belated or later revised claim cures that statutory failure.
Common review failures
Typical errors are testing only the individual cap, allocating the same profit to two incentives, using gross receipts in an income-based formula, and overlooking an understated cost of internal inputs. Another error is using the gross-total-income ceiling as a new entitlement to relief prohibited by the chosen regime. Preserve a deduction-by-deduction eligibility file and a separate common-limit reconciliation. Unused expenditure or a disallowed excess does not acquire a carry-forward merely because section 122 restricts the current deduction.

Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Aggregate ceiling
Assume a taxpayer’s correctly computed gross total income is ₹1,80,000 and otherwise permissible Chapter VIII deductions total ₹2,30,000, with no further special-income restriction. Aggregate allowance cannot exceed ₹1,80,000: ₹50,000 of the proposed total is blocked by the outer ceiling. The deduction cannot create a ₹50,000 loss.
Illustrative example 2: Permitted set-offs change the ceiling
Assume ₹4,20,000 of income is reduced by ₹3,50,000 of lawfully available set-off before Chapter VIII, leaving gross total income ₹70,000. Otherwise eligible deductions of ₹1,00,000 are limited to ₹70,000 on these facts. The ceiling difference is ₹30,000; the set-off eligibility must first be independently established.
Illustrative example 3: Gross receipts are not the Part C base
An eligible income stream has receipts ₹3,00,000 and ₹80,000 of expenditure deductible in computing that income. The section 122(9) starting base is ₹2,20,000, not ₹3,00,000. If the applicable deduction section independently permits 100% on these assumed facts, and all its caps and other restrictions are satisfied, the income-based amount is ₹2,20,000 before the aggregate ceiling.
Illustrative example 4: The same profit in two schedules
An eligible unit has computed profit ₹10,00,000. Relief of ₹6,00,000 on a clearly identified profit component has already been claimed and allowed under Part C. A second schedule seeks another ₹6,00,000 on exactly that component. Section 122(4) bars the duplicate ₹6,00,000; the two entries cannot produce ₹12,00,000 of relief. No conclusion is assumed about relief on a genuinely different remaining component.
Illustrative example 5: AOP deduction and a member’s share
Assume a ₹60,000 section 133 deduction is admissible to an AOP and a member has a 40% income share. The member proposes ₹60,000 × 40% = ₹24,000 again in relation to that share. Section 122(3) blocks that repeated ₹24,000. A separate qualifying donation made by the member would require its own factual and statutory analysis.
Illustrative example 6: Underpriced internal input
An eligible unit’s provisional profit is ₹5,00,000 after charging ₹2,00,000 for goods obtained from another business of the same assessee. Reliable evidence establishes the applicable section 122(7) market value at ₹2,60,000; assume no other adjustment. Increase the eligible-unit input cost by ₹60,000 and reduce its profit to ₹4,40,000. Recompute the deduction on that corrected base rather than retaining the inflated ₹5,00,000.

Sixteen practitioner FAQs
1. Does section 122 create a standalone deduction?
No. It governs deductions authorised by Chapter VIII and operates alongside the underlying section’s conditions.
2. Is gross total income simply gross receipts?
No. It is income computed under the Act before Chapter VIII deductions.
3. Can aggregate Chapter VIII deductions exceed gross total income?
No. Section 122(2) expressly imposes that ceiling.
4. Does the ceiling waive each individual section’s cap?
No. Apply the individual entitlement and restrictions before the common ceiling.
5. Can Chapter VIII deductions manufacture a loss?
The aggregate ceiling prevents deductions exceeding gross total income; it is not a loss-creation provision.
6. Must loss set-offs be examined first?
Yes. Lawfully applicable computation and set-off rules affect the pre-Chapter VIII income figure.
7. Does a profitable unit guarantee full profit relief?
No. The relevant Part C section, regime, computed income and common restrictions all need examination.
8. What is the section 122(4) overlap test?
Identify the same profits already claimed and allowed under Part C and prevent another deduction to that extent.
9. Is a differently named incentive necessarily separate?
No. Trace the underlying profit component rather than relying on schedule labels.
10. Can an AOP member repeat every entity deduction pro rata?
Subsection (3) bars the specified deductions in relation to the member’s share where admissible to the AOP/BOI.
11. Do internal business transfers escape valuation scrutiny?
No. Covered transfers at non-market consideration require the eligible-business profit adjustment under subsection (6).
12. Is the book transfer price conclusive?
No. The subsection (7) definition and supporting market or arm’s-length evidence control.
13. Is every internal transfer a specified domestic transaction?
No. Determine section 164 applicability separately rather than assuming it from common ownership.
14. Can a Part C claim ignore return filing time?
No. Section 122(5) contains both timely-filing and return-claim conditions.
15. Can unused deduction amounts automatically move to next year?
No. Any carry-forward requires an independently applicable statutory provision.
16. Does this working determine the final tax payable?
No. Rates, rebates, special-income restrictions, surcharge, cess and credits remain separate computations.
Conclusion
Apply section 122 before finalising Chapter VIII claims: establish gross total income, remove overlapping relief and test eligible-unit income and filing conditions.
