Section 113 of the Income-tax Act, 2025 — Carry Forward and Set-off of Speculation Business Loss

In plain language

What Section 113 says in plain English

Section 113 of the Income-tax Act, 2025 deals with what happens to a loss from a speculation business. It is the successor to the old Section 73 of the Income-tax Act, 1961, and the substance is largely unchanged. The rule is simple but strict: a speculation loss lives in its own "silo". It cannot be mixed with your normal business profit, salary, house property income, capital gains or interest income. It can only fight against speculation profit.

• Set-off in the same year: A loss from a speculation business can be set off only against the profits and gains of another speculation business in that same tax year.
• Carry forward: If the loss cannot be fully absorbed in the current year (because there is no or not enough speculation profit), the unabsorbed part is carried forward to the next year and set off against speculation profit of that year, and so on.
• 4-year limit: A speculation loss cannot be carried forward for more than four tax years immediately after the year in which the loss was first computed. This is much shorter than the 8-year limit for a normal business loss.

What is a "speculation business"?

Under the Act, a speculation transaction is one where a contract for purchase or sale of a commodity, stocks or shares is settled otherwise than by actual delivery — that is, you square off with a difference payment rather than taking delivery. When such transactions form a distinct business, that is a speculation business. Classic examples are intraday equity trading (buy and sell the same scrip the same day without delivery) and certain jobbing/hedging done without delivery.

Important: Trading in derivatives (futures and options) on a recognised stock exchange and commodity derivatives with a proper mechanism are treated as non-speculative business under the separate definition, so F&O losses are NOT governed by Section 113 — they are ordinary business losses. This is a very common point of confusion.

The deeming rule for companies (Explanation)

Section 113 carries forward the old "Explanation to Section 73" deeming rule. Where any part of the business of a company consists of the purchase and sale of shares of other companies, that company is deemed to be carrying on a speculation business to the extent of such share dealing — even if the shares were bought with delivery. This prevents companies from converting share losses into ordinary business losses.

Exceptions — the deeming does NOT apply to a company:

• whose gross total income mainly consists of income under the heads "Income from house property", "Capital gains" and "Income from other sources"; or
• whose principal business is trading in shares, or banking, or the granting of loans and advances (money-lending).

Who it applies to

• Individuals and HUFs doing intraday share trading or other non-delivery-based trading.
• Firms, LLPs and companies running a speculation business.
• Companies dealing in shares that fall inside the deeming rule above.

Key conditions to actually claim the carry forward

• File the return on time: To carry forward a speculation loss, you must file your income-tax return on or before the due date under Section 263(1) (the 2025 Act's equivalent of the old Section 139(1)). A belated return kills the carry-forward.
• Same-year set-off is allowed even with a late return, but future carry forward is not.
• Same nature only: The carried-forward loss retains its speculation character and can only meet future speculation profit.
• Continuity of business is not required — unlike Section 112 (normal business loss) which needs the same business, Section 113 allows set-off against any speculation business.

How it interacts with other sections

Section 113 sits inside the set-off/carry-forward chapter. Normal business loss carry forward is under Section 112 (old Section 72), unabsorbed depreciation under the relevant allowance sections, and the general inter-head set-off rules under Sections 108–109. Speculation profit itself is still computed under the "Profits and gains of business or profession" head, but the loss is ring-fenced by Section 113.

Practical implications

If you are an intraday trader, keep your speculation books separate. A big intraday loss cannot reduce your salary or delivery-based capital gains tax — you can only recover it against future intraday profit within four years, and only if you file on time. For companies, understand whether the deeming rule pulls your share losses into the speculation silo before you plan set-offs.
