Income-tax Act, 1961 | Business losses
Section 73 of Income-tax Act, 1961: Speculation Business Losses
Section 73 governs how losses from a speculation business may be set off and carried forward. The central rule is that a speculation loss cannot be adjusted against ordinary business profits; it is restricted to profits of a speculation business, subject to the applicable law.
What is a speculation business?
Speculative transaction: Under Section 43(5) of the 1961 Act, broadly, a contract for purchase or sale of a commodity, including stocks and shares, settled otherwise than by actual delivery or transfer is a speculative transaction. The definition has important statutory exceptions, including qualifying hedging and eligible derivatives transactions. Not every intraday or derivative transaction is automatically classified alike.
Speculation business: Under Explanation 2 to Section 28, where speculative transactions are of such a nature as to constitute a business, that business is deemed distinct and separate from any other business.
Set-off means adjustment of an eligible loss against income. Carry-forward means retaining an unadjusted eligible loss for possible set-off in later assessment years. Assessment year is the year in which income of the preceding previous year was assessed under the 1961 Act.
Rules under Section 73 at a glance
| Provision | Effect |
|---|---|
| Section 73(1) | Speculation business losses can be set off only against profits and gains of another speculation business. |
| Section 73(2) | Unadjusted speculation losses may be carried forward and used against eligible speculation profits in later years. |
| Section 73(3) | Section 72(2) priority rules apply to depreciation and qualifying scientific research allowances. |
| Section 73(4) | Carry-forward generally cannot exceed four assessment years immediately following the year the loss was first computed. |
| Explanation | In specified circumstances, purchase and sale of shares of other companies by a company is deemed speculation business, subject to statutory exceptions. |
The four-year limit is distinct from the eight-year period generally associated with eligible non-speculative business losses under Section 72 of the 1961 Act. The loss year is the starting point: later set-off does not restart the four-year clock.
Section 73: statutory provisions in the original webpage
Sub-section (1): restriction on set-off
Any loss, computed in respect of a speculation business carried on by the assessee, shall not be set off except against profits and gains, if any, of another speculation business.
Sub-section (2): carry-forward
Where for any assessment year any loss computed in respect of a speculation business has not been wholly set off under sub-section (1), so much of the loss as is not so set off or the whole loss where the assessee had no income from any other speculation business, shall, subject to the other provisions of this Chapter, be carried forward to the following assessment year, and--
(i) it shall be set off against the profits and gains, if any, of any speculation business carried on by him assessable for that assessment year; and
(ii) if the loss cannot be wholly so set off, the amount of loss not so set off shall be carried forward to the following assessment year and so on.
Sub-section (3): depreciation and scientific research allowance
In respect of allowance on account of depreciation or capital expenditure on scientific research, the provisions of sub-section (2) of section 72 shall apply in relation to speculation business as they apply in relation to any other business.
Sub-section (4): time limit
No loss shall be carried forward under this section for more than four assessment years immediately succeeding the assessment year for which the loss was first computed.
Explanation: certain share-trading companies
Where part of the business of a company consists of purchase and sale of shares of other companies, the Explanation can deem that part to be speculation business. It excludes companies meeting the statutory principal-income test and companies whose principal business is trading in shares, banking, or granting loans and advances. The exact words and their application must be checked for the assessment year in question.
Original Explanation and legislative amendment notes

Where any part of the business of a company (other than a company whose gross total income consists mainly of income which is chargeable under the heads "Interest on securities", "Income from house property", "Capital gains" and "Income from other sources", or a company the principal business of which is the business of trading in shares or banking or the granting of loans and advances) consists in the purchase and sale of shares of other companies, such company shall, for the purposes of this section, be deemed to be carrying on a speculation business to the extent to which the business consists of the purchase and sale of such shares.

Share trading, derivatives and the deeming Explanation
The deeming Explanation to Section 73 is a separate legal test from the definition of a speculative transaction in Section 43(5). It can treat certain company share-dealing activities as speculation business even where delivery-based share transactions would not ordinarily be speculative under Section 43(5). The exceptions depend on the company's income composition and principal business.
For Section 43(5), eligible transactions in derivatives carried out on a recognised stock exchange may fall within statutory exceptions to speculative transactions, subject to conditions. Whether a particular derivatives or share-trading loss is speculative requires examination of the transaction, entity and relevant year; it should not be determined solely from the label "F&O" or "share trading".
Illustration of speculation loss set-off
Suppose a taxpayer incurred a speculation business loss of Rs. 3,00,000 in an assessment year governed by Section 73. In the next assessment year, the taxpayer earns Rs. 1,20,000 from another speculation business and Rs. 4,00,000 from an ordinary business. Subject to other applicable conditions, Rs. 1,20,000 of the loss may be set off against speculation profits. The remaining Rs. 1,80,000 may be carried forward within the original four-year limit. It cannot be set off against the Rs. 4,00,000 ordinary business profit merely because both are business income.
Return filing and supporting records
- Classify transactions correctly under Sections 28 and 43(5), and consider the separate deeming Explanation to Section 73.
- Maintain year-wise schedules showing the original loss year, losses utilised, balance and expiry year.
- Consider Section 139(3) and Section 80 of the 1961 Act: timely filing of a return of loss is generally essential for carry-forward of business and speculation losses, subject to statutory exceptions.
- Keep contract notes, trading statements, financial accounts, audit documentation where applicable, and previous tax-return acknowledgments.
- For post-commencement tax years, confirm the corresponding requirements under the Income-tax Act, 2025 and transitional provisions.
