Section 72 Income Tax Act: Carry Forward and Set-Off of Business Losses
Section 72 of the Income-tax Act, 1961 governs the carry forward and subsequent set-off of ordinary business or professional losses that cannot be fully adjusted in the year in which they arise. The provision distinguishes non-speculative business losses from speculation losses and generally limits the carry-forward period to eight assessment years.
What does Section 72 mean?
A business loss arises when allowable business or professional deductions exceed the income computed under the head "Profits and gains of business or profession". A set-off is an adjustment of a permitted loss against taxable profits or income. Carry forward means preserving the eligible unadjusted balance for a later assessment year, subject to statutory conditions.
Section 72 deals with ordinary, non-speculative business losses. Losses from speculation business are governed separately by Section 73, while specified business losses may be governed by Section 73A.
Section 72: Explanation of each provision
Section 72(1): Carry forward and future set-off
If a non-speculative business or professional loss cannot be fully adjusted in the same year under Section 71, the unabsorbed portion may be carried forward, subject to Chapter VI. In a later eligible assessment year, it can be adjusted against profits and gains of any business or profession carried on by the same assessee and assessable for that year. The future business need not ordinarily be the identical business that generated the loss.
Section 72(1)(ii): Balance carried to subsequent years
If only part of the carried-forward loss can be absorbed by eligible business profits in the next year, the remaining amount may be carried forward again, subject to the applicable time limit and other statutory conditions.
Special proviso: Business discontinued in circumstances covered by Section 33B
Section 72(1) contains a special proviso concerning a business discontinued in the circumstances specified in Section 33B and subsequently re-established, reconstructed or revived within the prescribed three-year period. The qualifying loss attributable to that business is treated under the proviso and may be set off against profits of that or another business carried on by the assessee. Any remaining eligible loss can be carried forward for seven assessment years immediately succeeding the relevant year, where the statutory requirements are met. This is a narrowly defined exception, not a general extension for every discontinued business.
Section 72(2): Priority over specified carried-forward allowances
Where allowances are carried forward under Section 32(2) (unabsorbed depreciation) or Section 35(4), the statute directs that effect must first be given to Section 72. Consequently, eligible brought-forward business losses are generally adjusted before those carried-forward allowances, subject to the complete statutory scheme.
Section 72(3): Eight-assessment-year limit
Except for the loss covered by the special proviso to Section 72(1), a business loss cannot be carried forward under Section 72 for more than eight assessment years immediately succeeding the assessment year in which the loss was first computed. An unused balance ordinarily lapses after that period.
Key conditions and restrictions
- Nature of loss: Section 72 ordinarily covers non-speculative business or professional losses, not capital losses or speculation losses.
- Eligible future income: Brought-forward Section 72 losses are set off against eligible business or professional profits, not salary, house-property income, or capital gains.
- Same assessee: The loss generally belongs to the assessee who incurred it; statutory exceptions, such as qualifying reorganisations under Section 72A, require separate examination.
- Return filing: Sections 80 and 139(3) generally require a return declaring a business loss to be filed within the prescribed due date to preserve carry-forward eligibility, subject to applicable legal exceptions or relief.
- Other limits: Sections 71(2A), 73, 73A, 78 and 79, among other provisions, may affect set-off or carry-forward depending on the facts.
Practical examples
| Scenario | Tax treatment |
|---|---|
| Eligible non-speculative business loss of Rs. 6,00,000; Rs. 2,00,000 adjusted in the loss year | Subject to compliance, the remaining Rs. 4,00,000 may be carried forward. |
| Next year, eligible business profit of Rs. 2,50,000 | Up to Rs. 2,50,000 of the brought-forward loss may be set off; Rs. 1,50,000 remains available within the original eight-year window. |
| Next year, only salary income of Rs. 8,00,000 | The brought-forward Section 72 business loss cannot be set off against salary income. |
| Loss remains unused after the permitted eighth succeeding assessment year | The ordinary Section 72 carry-forward entitlement expires. |
Examples are illustrative and assume the loss is validly determined, the return requirements are satisfied and no special restriction applies.
