Speculation Loss Set Off and Carry Forward under Income-tax Act, 2025

Updated 11 October 2026 · Fact-checked

Under section 113 of the Income-tax Act, 2025, a loss from speculation business can be set off only against profits of another speculation business. Any unabsorbed loss is carried forward to the following tax year, again set off only against speculation profits, for at most four tax years after the year of loss.

Understand Losses from Speculation Business

A speculation business is a business where you deal in a way the Act treats as speculative, such as settling transactions without actual delivery. The Act keeps its results in a separate compartment. The compartment can take in losses only from speculation, and it can give them up only to speculation profits.

The rule has two parts. First, a speculation loss can be set off only against profits and gains of another speculation business (section 113(1)). You cannot use it against salary, house property, capital gains, other sources or normal business profit. Second, if it cannot be wholly set off in that year, the balance is carried forward to the next tax year and set off against speculation profits of that year, and so on (section 113(2)).

There is a time limit. No speculation loss is carried forward for more than four tax years immediately succeeding the tax year in which it was first computed (section 113(3)). After that, the unabsorbed loss lapses.

Section 113 restricts only the speculation loss. It does not say how a normal business loss is treated against speculation profit. That depends on the general set off provisions in section 109, so check them before you answer on that point. Compare this with normal business loss under section 112, which can be carried forward for up to eight tax years and set off against profits of any business or profession.

There is also a special rule for companies. If part of a company's business consists of purchase and sale of shares of other companies, it is deemed to carry on speculation business to that extent (section 113(5)). This deeming does not apply if its 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 (section 113(6)).

Key rules to remember

Set off in the same year: Speculation loss → only against profits of another speculation business; Section 113(1). No set off against any other head or non-speculation business income.
Carry forward: Unabsorbed loss → next tax year → speculation profits only → repeat; Section 113(2). The loss is set off against speculation business profits of the later year.
Time limit: Maximum 4 tax years immediately succeeding the year of loss; Section 113(3). Count from the year after the loss year. The loss year itself is not counted.
Deemed speculation for companies: Share trading part of a company's business = speculation business, to that extent; Section 113(5). Not applicable under section 113(6) for companies with mainly house property, capital gains or other sources income, or whose principal business is share trading, banking or lending.
Order with allowances: Section 113 effect is given first, then carry forward of allowance under section 33(11) or 45(7); Section 113(4), for allowances related to the speculation business.

How to solve Losses from Speculation Business questions

Use this method for any question asking how a speculation loss is treated.

1Identify whether the loss is from speculation business. Separate it from normal business loss and other heads.
2Check the current year: find profits of any other speculation business. Set off the loss only against those.
3If the loss is not fully absorbed, compute the balance and carry it forward to the next tax year.
4In each later year, set off the brought forward loss only against speculation profits of that year. It cannot be set off against any other income.
5Count the years. The loss can be carried forward only for four tax years immediately after the loss year. Lapse any balance after that.
6If the assessee is a company dealing in shares, test section 113(5) and the exceptions in 113(6).
7Write a conclusion: amount set off, amount carried forward, and amount lapsed, citing section 113.

Quickest way: Speculation compartment table

When to use it: Use for numerical questions covering several years of speculation profits and losses.

Draw one column per tax year and mark only speculation profit or loss.
In the loss year, write the loss and note the last year it can be used (loss year + 4).
In each later year, set off the brought forward loss against speculation profit, up to the profit available. If losses of several years are brought forward, the usual practical convention is to use the earlier years' losses first so they do not lapse. Section 113 does not itself lay down an order.
Anything left after the fourth succeeding year lapses.
Write that no part touches other heads, and cite section 113.

Common mistakes in Losses from Speculation Business

Setting off a speculation loss against salary, capital gains or normal business profit.
Students apply the general inter-head set off rule without checking the special rule.
Fix: Remember the compartment: speculation loss goes only against speculation profit, as stated in section 113(1).
Using eight years for carry forward.
Eight years applies to normal business loss, house property loss and capital loss, so it is confused with speculation loss.
Fix: Speculation loss is limited to four tax years immediately succeeding the loss year under section 113(3).
Counting the loss year as the first of the four years.
Students count from the year in which the loss arises.
Fix: The four years are those immediately succeeding the loss year. A loss of one tax year can be used in the next four.
Assuming section 113 also decides whether a normal business loss can be set off against speculation profit.
Students assume the compartment rule works in both directions.
Fix: Section 113 restricts only the speculation loss. For a normal business loss against speculation profit, the answer depends on the general set off provisions in section 109, so check them instead of relying on section 113.
Treating every share trade of a company as speculation.
Section 113(5) is remembered without its exceptions.
Fix: Check section 113(6): the deeming does not apply where gross total income is mainly house property, capital gains or other sources, or the principal business is share trading, banking or lending.

Worked examples

Example 1

Rohan has speculation loss of ₹80,000 in tax year 1. In tax year 1 he also has business profit of ₹2,00,000 from his textile shop and salary of ₹5,00,000. Can the loss be set off in year 1? What happens to it?

Show the solution

The loss is from speculation business, so section 113(1) allows set off only against profits of another speculation business.
Rohan has no other speculation business profit in year 1. Salary and textile profit cannot absorb the loss.
The whole ₹80,000 is carried forward to tax year 2 under section 113(2).
It can be set off against speculation profits in the following four tax years only, that is years 2 to 5 (section 113(3)).

Answer: No set off in year 1. The entire ₹80,000 is carried forward and can be set off only against speculation profit of the next four tax years.

Example 2

Meera has speculation loss of ₹1,50,000 in tax year 1. Her speculation profits are: year 2 ₹40,000, year 3 nil, year 4 ₹60,000, year 5 ₹30,000, year 6 ₹90,000. She has large other income every year. Compute set off and the amount that lapses.

Show the solution

The loss arose in year 1. It can be carried forward for four tax years immediately succeeding, so years 2, 3, 4 and 5. Year 6 is outside the limit.
Year 2: set off ₹40,000. Balance ₹1,10,000.
Year 3: no speculation profit, so nothing is set off. Balance ₹1,10,000.
Year 4: set off ₹60,000. Balance ₹50,000.
Year 5: set off ₹30,000. Balance ₹20,000.
Year 6: the remaining ₹20,000 cannot be carried forward beyond year 5, so it lapses. Year 6 profit of ₹90,000 is fully taxable.
Check: 40,000 + 60,000 + 30,000 = ₹1,30,000 set off. 1,50,000 − 1,30,000 = ₹20,000 lapses.

Answer: ₹1,30,000 is set off across years 2, 4 and 5. ₹20,000 lapses after year 5 under section 113(3). Meera's year 6 speculation profit is fully taxable.

Exam tips

Write the section number 113 and quote the three points: only against speculation profit, carry forward, four tax years.
In numerical answers, show a year-wise table with opening loss, set off, and closing balance, and mark the lapse year.
Contrast with section 112 (eight years, any business profit) in one line when the question mixes loss types.
For company questions, test section 113(5) and then the 113(6) exceptions before concluding.
State clearly that other heads cannot absorb speculation loss even when they are positive.

Losses from Speculation Business: frequently asked questions

Can speculation loss be set off against salary or capital gains?

No. Under section 113(1) it can be set off only against profits and gains of another speculation business. Other heads and normal business profit cannot absorb it.

For how many years can a speculation loss be carried forward?

For not more than four tax years immediately succeeding the tax year in which the loss was first computed, under section 113(3). After that, the unabsorbed loss lapses.

Can speculation loss be carried forward if the return is not filed?

The text of section 113 does not mention it. Check the return-filing conditions for carry forward of losses in the Act's provisions on returns and state them separately in your answer.

Can a normal business loss be set off against speculation profit?

Section 113 restricts only the set off of speculation loss. It does not deal with normal business loss against speculation profit. That depends on the general set off provisions in section 109, so check them and state the answer from there.
