A speculation loss cannot absorb every business profit
For tax years beginning from 1 April 2026, section 113 of the Income-tax Act, 2025 ring-fences speculation-business losses. Current loss can be set off only against profits of another speculation business; an eligible brought-forward loss can be used against speculation-business profits of the assessee. The carry-forward limit is four tax years immediately succeeding the year for which the loss was first computed. This guide addresses utilisation after classification, not an opinion that an unidentified share or derivative transaction is speculative.
Classify trades before computing the loss
Section 66(31) defines speculative transactions by reference to settlement otherwise than actual delivery or transfer, with stated exclusions for specified derivative transactions and qualifying hedging, jobbing and arbitrage contracts. Section 66(33) contains conditions for specified derivatives, including exchange, intermediary and contract-note requirements. Neither an “F&O” spreadsheet label nor the ordinary meaning of investment risk settles classification. Retain contracts and settlement evidence; distinguish investment losses from business losses.
Companies have an additional share-business test
Section 113(5) deems a company’s business of purchasing and selling shares of other companies to be speculation business to that extent. Actual delivery does not alone close this enquiry. Subsection (6) excludes the specified income-composition and principal-business cases, including principal share trading, banking or granting loans and advances. Review actual income and business evidence. Do not extend this company-only rule to individuals or invent a universal percentage test for “mainly”.
Return eligibility and expiry are separate controls
Section 121 requires the loss to be determined pursuant to a return filed under section 263(1) for the specified carry-forward provisions, including section 113(2). Check the operative due date and any valid extension against accepted filing evidence. Current-year set-off and future carry-forward are separate questions. A book loss alone proves neither tax quantum nor carry-forward eligibility.
Keep a cohort register rather than one opening balance
Track original year, eligible amount, utilisation, remaining balance and final usable year. A year without profit does not pause the four-year window. Section 113(4) gives the loss provision priority where the stated carried-forward depreciation or allowance relating to that speculation business is involved; keep those allowances separate. Pre-2026 losses need section 536 transition review: commencement does not restart their original period, change their character or revive an ineligible claim. Examples assume legally established classification and eligibility and compute loss utilisation only, without final tax, surcharge or cess.

Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Current loss against another speculation business
Assume established speculation loss ₹1,20,000 and profit of another speculation business ₹70,000. Set-off is ₹70,000; the unabsorbed loss is ₹50,000, subject to carry-forward eligibility.
Illustrative example 2: Ordinary business profit is separate
Assume speculation loss ₹80,000, ordinary business profit ₹2,00,000 and no speculation profit. Section 113 set-off against that ordinary profit is ₹0; it is not reduced to ₹1,20,000 by this loss.
Illustrative example 3: Brought-forward use
An eligible unexpired speculation loss of ₹90,000 meets current speculation profit ₹1,40,000. Utilisation is ₹90,000, leaving ₹50,000 speculation profit and no balance of that loss.
Illustrative example 4: Four succeeding years
A qualifying loss first computed for tax year 2026–27 has succeeding years 2027–28, 2028–29, 2029–30 and 2030–31. The fifth, 2031–32, is outside that loss’s section 113 window.
Illustrative example 5: Expired and live cohorts
Assume a separately confirmed expired ₹30,000 cohort and an eligible unexpired ₹80,000 cohort. Against ₹60,000 speculation profit, use ₹60,000 from the live cohort, leaving ₹20,000 there. Do not revive the expired ₹30,000.
Illustrative example 6: Priority working
Assume ₹1,00,000 speculation profit before relevant carried-forward claims, eligible speculation loss ₹70,000 and qualifying allowance ₹50,000 relating to that business. First use ₹70,000 loss. Only ₹30,000 profit remains for that allowance, leaving ₹20,000 allowance subject to its own rules.

Classification, filed return, original cohort, prior utilisation and expiry.
Conclusion
Section 113 restricts speculation-business losses to speculation profits and permits qualifying balances to move forward for four succeeding tax years. Classify the transactions, apply the company-specific deeming rule and preserve timely-return and original-expiry evidence.
