Deemed Profits, Speculation and Business Losses: Set Off and Carry Forward

Updated 10 October 2026 · Fact-checked

Speculation business loss under the Income-tax Act, 2025 can be set off only against profits of another speculation business. Unabsorbed loss is carried forward and set off only against speculation profits, for up to four tax years after the loss year. Ordinary business loss follows section 112 with an eight-year limit.

Understand Deemed Profits, Speculation and Business Losses

A business loss is not always treated the same way. The Act sorts business losses into three baskets: ordinary business loss, speculation business loss and specified business loss. Each basket has its own set-off and carry forward rules. Your job in the exam is to put each loss in the right basket first.

An ordinary business loss is any loss under the head Profits and gains of business or profession that is not from speculation (and not from a specified business). If it cannot be set off against income of other heads under section 109, section 112 carries it forward. It can be set off only against business or profession profits of later years. The limit is eight tax years immediately after the loss year.

A speculation business loss is dealt with by section 113. It can be set off only against profit of another speculation business. If it cannot be fully set off in the same year, the balance is carried forward and set off only against speculation business profits of later years. No loss is carried forward for more than four tax years immediately after the year in which it was first computed.

Section 113(5) adds a deeming 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. Section 113(6) switches this off if the company's gross total income consists mainly of income from house property, capital gains or other sources, or if its principal business is trading in shares, banking or granting loans and advances.

A specified business loss falls under section 114. It can be set off only against profits of another specified business. Section 114 as supplied states set-off and carry forward, but it gives no time limit. Do not add a number of years that the text does not state.

The rule exists to ring-fence risky or specially treated activities. Speculation losses cannot reduce your salary, rent or ordinary business profits. But a speculation profit can be absorbed by an ordinary business loss in the same year, because the restriction only works one way: it limits where speculation losses go, not what can be set against speculation profits.

Key rules to remember

Ordinary business loss carry forward (section 112): Loss not set off under section 109 → carried forward → set off against business or profession profits of later years, up to 8 tax years; The loss must not be a speculation loss. It can be set off against any business profit, including speculation profit.
Specified business loss (section 114): Set off only against profits of another specified business; unabsorbed balance carried forward against specified business profits; The supplied text of section 114 states no number of years.

Worked examples

Example 1

Mr. Rohan Mehta has the following results for the tax year 2026-27: ordinary business profit ₹6,00,000; speculation business loss ₹2,50,000. Brought forward from earlier years: nil. Compute the business income and the loss carried forward.

Show the solution

Speculation loss of ₹2,50,000 can be set off only against another speculation business profit.
He has no other speculation business, so no set off is allowed in 2026-27.
Ordinary business profit stays at ₹6,00,000.
The unabsorbed speculation loss of ₹2,50,000 is carried forward under section 113(2).
It can be set off only against speculation profits for the four tax years immediately succeeding 2026-27, that is up to 2030-31.

Answer: Business income for 2026-27 is ₹6,00,000. Speculation loss of ₹2,50,000 is carried forward, usable against speculation profits up to tax year 2030-31.

Example 2

Ms. Kavita Rao has the following for the tax year 2026-27: profit from speculation business A ₹1,80,000; loss from speculation business B ₹70,000; loss from ordinary business ₹90,000; income from house property ₹2,00,000. Brought forward speculation loss: ₹60,000. Compute the net result and loss carried forward.

Show the solution

Set off current-year speculation loss against speculation profit: ₹1,80,000 − ₹70,000 = ₹1,10,000.
Set off brought forward speculation loss against speculation profit: ₹1,10,000 − ₹60,000 = ₹50,000 net speculation profit.
Ordinary business loss of ₹90,000 can be set off against other heads under section 109. Assume it is set off against house property income: ₹2,00,000 − ₹90,000 = ₹1,10,000. It could equally be set off against the speculation profit, as the restriction applies only to speculation losses.
Taking the house property route, gross total income is ₹50,000 + ₹1,10,000 = ₹1,60,000.
No loss is left to carry forward.

Answer: Net speculation profit is ₹50,000, house property income after set off is ₹1,10,000, gross total income is ₹1,60,000 and no loss is carried forward. Brought forward speculation loss is fully used.

For company questions, test section 113(5) and the section 113(6) exceptions before computing.
