Speculation Business Losses under Section 113: Set Off and Carry Forward

Updated 10 October 2026 · Fact-checked

A speculation loss under section 113 of the Income-tax Act, 2025 can be set off only against profits of another speculation business. Any unabsorbed loss is carried forward to the following tax years, up to four tax years after the year it was first computed, and set off only against speculation profits.

Understand Speculation Business Losses (Section 113)

Some businesses earn profit or loss from speculative deals, for example transactions settled without actual delivery. The Act treats this as a separate business. The reason is simple: the law does not want a person to reduce tax on normal income by booking speculative losses.

So section 113 ring-fences the loss. A loss computed in a speculation business can be set off only against profits and gains of another speculation business. It cannot be set off against salary, house property, capital gains, other sources, or normal business profit.

If the loss is not wholly absorbed in the year, it is carried forward to the following tax year. There it is set off only against profits of speculation business carried on by you in that year. What remains moves on again. No loss can be carried forward for more than four tax years immediately after the tax year in which it was first computed.

There is also a deemed rule for companies. If part of a company's business is purchase and sale of shares of other companies, it is deemed to carry on speculation business to that extent. This deeming does not apply if the company's gross total income consists mainly of income under house property, capital gains or other sources, or if its principal business is trading in shares, banking, or granting loans and advances.

Compare this with a normal business loss under section 112. That loss can be set off against other heads in the same year (as per section 109), and the balance can be carried forward against any business or profession profits for up to eight tax years. Speculation losses get much tighter treatment.

Key rules to remember

Current-year set off (s.113(1))
Speculation loss → set off only against profits of another speculation business
No set off against normal business profit or any other head.
Carry forward (s.113(2))
Unabsorbed speculation loss → next tax year → speculation profits only → repeat
Set off against profits of any speculation business carried on by you in that year.
Time limit (s.113(3))
Maximum 4 tax years immediately succeeding the tax year of first computation
Compare: normal business loss under s.112 is 8 tax years; house property and capital loss also 8 years.
Company share trading (s.113(5))
Company's purchase and sale of shares of other companies = speculation business to that extent
Exceptions in s.113(6): income mainly from house property, capital gains or other sources; or principal business is share trading, banking, or granting loans and advances.
Order of giving effect (s.113(4))
Give effect to s.113 first, then to allowances under s.33(11) or s.45(7) related to the speculation business
Applies where such an allowance or part of it is to be carried forward.

How to solve Speculation Business Losses (Section 113) questions

Use this method for any question on speculation loss, whether it asks for set off, carry forward or the final total income.

  1. 1Identify each business and mark which are speculation businesses and which are normal. For a company, check whether the deeming rule for share dealing applies.
  2. 2Compute the profit or loss of each speculation business and of each normal business separately.
  3. 3Net the current-year speculation profits and losses against each other only.
  4. 4If a net speculation loss remains, do not set it off against any other head or normal business. Carry it forward.
  5. 5In later years, set off brought-forward speculation loss only against speculation profit of that year, oldest loss first.
  6. 6Check the four-tax-year limit for each year's loss. Lapse any loss beyond it.
  7. 7Show the final figures: income of other heads untouched, speculation loss carried forward with the year up to which it is available.

Quickest way: Ring-fence and count four years

When to use it: Use when a numerical asks for total income or loss to be carried forward and time is short.

  1. Draw two columns: Speculation and Everything else.
  2. Put the speculation result in the first column; it never crosses over as a loss.
  3. Compute total income from the second column as usual.
  4. Write the carry forward with its last usable tax year: first year + 4.

Common mistakes in Speculation Business Losses (Section 113)

  • Setting off a speculation loss against normal business profit or salary.

    Students remember the general inter-head set off rule and apply it to all losses.

    Fix: Remember section 113(1): speculation loss goes only against speculation profit.

  • Carrying forward speculation loss for eight years.

    Confusion with normal business loss, which has an eight tax year limit.

    Fix: Speculation loss: four tax years. Normal business loss: eight tax years.

  • Counting the year of loss as one of the four years.

    The wording 'immediately succeeding' is read carelessly.

    Fix: The four years start from the next tax year. A loss of tax year 2026-27 can be carried to 2027-28 through 2030-31.

  • Treating a company's share dealing as normal business in every case.

    Students miss the deeming provision in section 113(5).

    Fix: Check the exceptions in section 113(6). If none applies, share trading is deemed speculation to that extent.

  • Assuming the speculation restriction also blocks a normal business loss from being set off against speculation profit.

    Students think the ring-fence works in both directions.

    Fix: Section 113 restricts only the speculation loss. It does not bar a normal business loss from being set off against speculation profit. For a brought-forward normal business loss, section 112(1)(i) allows set off against profits and gains of any business or profession carried on by you in that tax year. For current-year losses, apply the general set off rules from the set-off chapter and read the question's facts carefully.

Worked examples

Example 1

Mr. Arjun Mehta has the following results for tax year 2026-27: speculation business A loss ₹2,40,000; speculation business B profit ₹90,000; normal business profit ₹5,00,000; salary income ₹3,00,000. Find the income after set off and the loss to be carried forward.

Show the solution
  1. Both A and B are speculation businesses, so they are netted: ₹90,000 − ₹2,40,000 = loss of ₹1,50,000.
  2. The net speculation loss of ₹1,50,000 cannot be set off against normal business profit or salary (section 113(1)).
  3. Normal business profit ₹5,00,000 + salary ₹3,00,000 = ₹8,00,000 (before deductions).
  4. Carry forward ₹1,50,000 to tax year 2027-28, available up to tax year 2030-31 (four tax years).

Answer: Income from salary and normal business (other than speculation): ₹8,00,000 (before deductions); speculation loss of ₹1,50,000 carried forward, usable up to tax year 2030-31 against speculation profits only.

Example 2

Priya Traders has a speculation loss of ₹80,000 for tax year 2026-27 carried forward. In tax year 2027-28 it has speculation profit of ₹30,000 and normal business profit of ₹2,00,000. In 2028-29 it has speculation profit of ₹1,10,000. Show the set off.

Show the solution
  1. Tax year 2027-28: set off ₹30,000 of the brought-forward loss against speculation profit ₹30,000. Speculation income is nil.
  2. Balance loss: ₹80,000 − ₹30,000 = ₹50,000. It cannot be set off against the ₹2,00,000 normal business profit.
  3. Normal business profit ₹2,00,000 is taxed in full.
  4. Tax year 2028-29: set off the balance ₹50,000 against speculation profit ₹1,10,000. Taxable speculation income = ₹60,000.
  5. The loss is fully absorbed within the four-tax-year period ending 2030-31.

Answer: 2027-28: speculation income nil, normal income ₹2,00,000, loss c/f ₹50,000. 2028-29: speculation income ₹60,000 after set off, no loss left.

Exam tips

  • In MCQs, the usual traps are: set off against normal profit (wrong), eight years (wrong), four years (right). Check the options for these.
  • In written answers, quote section 113 and state the rule before the working. Step marks follow the layout.
  • Always show a carry forward statement with the last usable tax year.
  • For a company with share transactions, mention section 113(5) and the exceptions in 113(6) before treating it as speculation.
  • Use the Income-tax Act, 2025 terms: say 'tax year', not 'assessment year'.
