A carried business loss is not a deduction from every income head
For tax year 2026–27, section 112 of the Income-tax Act, 2025 permits a qualifying ordinary business loss to be carried forward and set off against profits of a business or profession carried on by the assessee. It does not allow a brought-forward balance to reduce salary merely because the taxpayer also runs a business. Separate the current-year computation, the eligible carried loss and unabsorbed depreciation before calculating the result.
Current law and the three separate ledgers
Use the Income-tax Act, 2025 as amended by the Finance Act, 2026, effective from 1 April 2026. Section 109 addresses current-year cross-head loss set-off, including its prohibition on business-loss set-off against salary. Section 112 governs ordinary carried business losses; sections 113 and 114 separately govern speculation and specified-business losses. Section 121 supplies a return-related eligibility requirement. A working headed only “business loss” can conceal materially different legal categories.
Keep one schedule for ordinary losses by source year, another for ring-fenced losses, and a separate allowance schedule for unabsorbed depreciation or other relevant carried allowances. Reconcile tax-computed losses to financial-statement results rather than importing the debit balance in retained earnings. Capital expenditure, disallowances and depreciation can make accounting and tax losses different.
Later profits need not come from the original activity
Section 112(1)(i) refers to profits and gains of any business or profession carried on by the assessee in the later tax year. It does not restrict the text to the identical original business. Verify that the profit is actually chargeable under the business/profession head and belongs to the same eligible assessee. Ordinary bank interest assessed as other-source income is not transformed into business profit by a bookkeeping label.
This article does not resolve succession, reorganisation or changes in company ownership. Those events can bring additional restrictions or special provisions. The illustrations assume the same taxpayer, ordinary eligible business income, no special income-set-off bar and no disputed characterisation. They show loss utilisation, not final tax or entitlement under a special regime.
Eight succeeding years, with no restart
Under section 112(2), the ordinary loss cannot be carried beyond eight tax years immediately succeeding the year for which it was first computed. A loss first computed for 2026–27 has a modelled window from 2027–28 to 2034–35. Partial use does not refresh that date. Keep the original year attached to the residue when rolling the schedule forward.
For a pre-1-April-2026 loss, separately verify the original determination and applicable saving or transition provisions. Do not convert a legacy assessment year into a new origin date. An oldest-expiring-first control can help manage several eligible buckets, but cannot override income-head matching or a substantive restriction.
Return eligibility and the priority working
Section 121 prevents carry-forward and set-off under section 112(1) for a loss not determined pursuant to a return filed under section 263(1). Check the actual return, applicable due date, valid extension and any specific relief. A later-year claim does not by itself establish the origin-year eligibility. Preserve processing or assessment evidence and the utilisation history.
Section 112(3) gives effect to this section before the carried allowance specified under section 33(11) or 45(7). Do not combine the ordinary loss and those allowances into one amount with one expiry. The ordering example below assumes the relevant carried allowance is otherwise available and the current-year profit has already been computed after current-year deductions. It illustrates priority only, without claiming that every allowance has the business loss’s time limit.
Common review failures
Look for carried losses incorrectly deducted from salary, current-year and brought-forward losses netted together without separate analysis, expired amounts retained indefinitely, and all depreciation treated as ordinary business loss. Resolve the difference at source-year level so the return can be reproduced from the file.
Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Partial use against later business profit
An eligible ordinary business loss brought forward is ₹3,00,000 and later eligible business profit is ₹2,20,000. Set-off is ₹2,20,000; unused loss is ₹80,000, retaining its original expiry.
Illustrative example 2: Salary does not absorb the balance
The taxpayer has ₹4,00,000 salary and an eligible brought-forward ordinary business loss of ₹1,50,000, but no business profit. Section 112 utilisation is ₹0. Salary remains ₹4,00,000 for this loss-matching exercise and the ₹1,50,000 stays subject to its original eligibility and expiry.
Illustrative example 3: Different business, same taxpayer
The same eligible proprietor has ceased the original trading activity but now earns ₹1,80,000 chargeable professional profit. A qualifying ordinary business loss of ₹1,20,000 can, on the stipulated facts, reduce that profit to ₹60,000. A transfer to a different taxpayer is not assumed.
Illustrative example 4: Current loss and brought-forward loss are different
In independent cases, ordinary current-year business loss of ₹50,000 and ₹70,000 ordinary other-source interest can leave ₹20,000 after section 109 matching, assuming no other restriction. A brought-forward section 112 loss of ₹50,000 with only the same ₹70,000 other-source interest has ₹0 utilisation under section 112: the ₹70,000 interest remains in that matching exercise.
Illustrative example 5: Original expiry survives partial utilisation
A ₹2,50,000 loss first computed for 2026–27 has eight succeeding years ending 2034–35. Eligible use of ₹1,00,000 in 2028–29 leaves ₹1,50,000, with the same 2034–35 endpoint. The utilisation does not extend the window to 2036–37.
Illustrative example 6: Loss priority over an otherwise available carried allowance
Assume ₹2,00,000 business profit after current-year deductions, eligible carried section 112 loss of ₹1,50,000 and an otherwise available specified carried allowance of ₹80,000. Give the business loss priority: ₹50,000 profit remains for the allowance. Applying ₹50,000 of that allowance leaves ₹0 profit and ₹30,000 allowance unabsorbed; do not relabel that ₹30,000 as ordinary business loss.

Sixteen practitioner FAQs
1. Is a debit balance in retained earnings enough?
No. Establish the tax-computed loss and the eligible determined amount.
2. Does section 112 cover speculation losses?
Its ordinary-loss rule excludes speculation loss; section 113 has separate provisions.
3. Can specified-business losses be pooled here?
Keep section 114’s separate category and restrictions identifiable.
4. Can a brought-forward ordinary loss reduce salary?
Not under section 112’s business/profession-profit matching rule.
5. Can it reduce ordinary other-source interest?
Not merely because the taxpayer owns a business; section 112 requires eligible business or professional profits.
6. Can current-year loss matching differ?
Yes. Section 109 addresses current-year cross-head matching, including its salary restriction.
7. Must the later profit come from the original business?
Section 112 refers to any business or profession carried on by the same assessee, subject to other applicable law.
8. Does a sale of the business transfer its tax losses automatically?
No. Succession and special transfer provisions require separate analysis.
9. What is the ordinary carry period?
At most eight tax years immediately succeeding the original loss year, subject to all eligibility requirements.
10. Does a partial claim restart the clock?
No. Preserve the source year and original endpoint.
11. Why retain the source-year return?
Section 121 links carry-forward under section 112 to determination pursuant to a return under section 263(1).
12. Can a later return cure origin-year eligibility by itself?
No. Verify the actual filing and any applicable extension or specific relief.
13. Does current-year depreciation form part of the priority illustration?
The example expressly starts after current-year deductions; it concerns carried balances.
14. Which carried amounts follow section 112 in its stated ordering?
Section 112(3) identifies the carried allowance under section 33(11) or 45(7).
15. Does every carried allowance expire with the business loss?
Do not assume that. Its governing provisions and eligibility need a separate schedule.
16. How should legacy losses be brought into the new-year file?
Retain original years, determinations and utilisation, and verify the relevant transition or saving provisions without resetting age.
Conclusion
A qualifying ordinary business loss carried forward under section 112 can meet later business or professional profits, not salary or ordinary interest income. Preserve the source year, return eligibility and priority over specified carried allowances.
