F&O Loss Carry Forward: Section 73 Restrictions vs Salary Loss Set-Off
F&O losses are non-speculative business losses, so Section 73's speculation restrictions do not apply. They set off against other business income in the same year — but never against salary under Section 71(2A) — and can be carried forward 8 years under Section 72. Filing ITR-3 on time is mandatory; a late return forfeits the carry-forward.

Short answer: F&O losses are non-speculative business losses, so Section 73 ITA 1961 (which confines speculation losses to set-off against speculation profit and limits carry-forward to 4 years) does not apply to them. An F&O loss can be set off in the same year against any non-speculative business income, capital gains, or income from other sources — but never against salary (s.71(2A)) — and the unabsorbed balance carries forward for 8 assessment years under s.72. The one hard condition: you must file ITR-3 on or before the due date. A late or missed return forfeits the entire carry-forward.

Which loss is which
Why Section 73 does not apply to F&O
Section 73 says a speculation-business loss "shall not be set off except against profits of another speculation business" and can be carried forward only 4 years. But F&O is not speculation. The proviso to s.43(5) excludes trading in derivatives on a recognised stock exchange from the definition of a speculative transaction, making F&O income non-speculative business income. Because the loss is non-speculative, the s.73 cage simply does not open — the more generous s.72 regime applies.
This matters in the most common scenario: a salaried trader with an F&O loss and a separate intraday/equity business profit. The F&O loss is available to set off against that business profit. A speculation loss would have been locked to speculation profits only.
Same-year set-off: the salary wall
The one wall that never moves is salary. Under s.71(2A), a business loss cannot be set off against income chargeable under the head "salary." Practically:
- F&O loss can reduce other business income (including a separate consultancy or another trading business) in the same year;
- F&O loss can reduce capital gains and "other sources" income in the same year —, as some practitioners take the stricter view that business losses should not travel to capital gains even though s.71(1) permits cross-head set-off;
- F&O loss cannot reduce taxable salary in any year, same year or future.
Plan around this: if your only income is salary and you have an F&O loss, the loss will simply be carried forward — it cannot give you a salary refund.
Carry forward: 8 years, but only if you file on time
The unabsorbed F&O loss carries forward up to 8 assessment years under s.72 and can be set off in those years against business income (and, subject to the same-year rules, other eligible heads). The precondition is brutal:
The return for the loss year must be filed on or before the due date under s.139(1) — or within the extended time allowed under s.139(4).
A return filed late (beyond s.139(4)) forfeits the carry-forward of the loss under s.80. You cannot fix it later, and the loss cannot be revived in an updated return under s.139(8A) for set-off purposes. This is the most expensive mistake a loss-making F&O trader can make.
Worked example: Karan's loss year
Persona: Karan, salaried at ₹20,00,000, FY 2025-26. F&O net loss ₹4,00,000; a small online consultancy business profit ₹1,20,000; interest income ₹60,000. He files ITR-3 on 25 July 2026 (on time).
Step 1 — Same-year set-off (s.71):
- F&O loss ₹4,00,000 → set off against consultancy ₹1,20,000 → balance ₹2,80,000.
- Balance → set off against interest ₹60,000 → balance ₹2,20,000.
- Salary ₹20,00,000 is untouchable.
Step 2 — Carry forward: The remaining ₹2,20,000 carries forward up to 8 years against future business income.
Step 3 — The alternative he avoided: If Karan had filed on 10 January 2027 (late, beyond s.139(4)), the ₹2,20,000 carry-forward would have been lost entirely — no future set-off, no amended return.
Step 4 — The s.73 scenario (not his case): had ₹4,00,000 been a speculative loss, it could only offset speculative profits and would expire after 4 years.

The profitable-year sequel
The carry-forward only has value if the future year has income it can reduce. In the year you carry the loss into, it sets off against business income first (including a fresh F&O profit or a consultancy), then — to the same extent permitted in a loss year — against other eligible heads under the s.71 ordering. If the loss is still unabsorbed after 8 years, it lapses; there is no revival. The trap in reverse: a profitable F&O year after a loss year should be filed on time and with the carried-forward loss claimed, because the AO does not apply it for you. Keep the loss-year ITR acknowledgment — it is the evidence the carry-forward existed at all.
Frequently Asked Questions
1. Can I carry forward an F&O loss for more than 8 years?
No. Under s.72, a non-speculative business loss can be carried forward for 8 assessment years. After that, the unabsorbed loss lapses.
2. Does Section 73 apply to F&O losses?
No. F&O is non-speculative business income under the proviso to s.43(5), so the s.73 speculation restrictions (speculation-only set-off, 4-year limit) do not apply.
3. Can my F&O loss be set off against my salary?
No. Section 71(2A) bars setting off business loss against salary income. The loss is available against other business income, capital gains, and other-source income in the same year, then carried forward.
4. What happens if I file my return late in a loss year?
The loss cannot be carried forward. Section 80 forfeits the carry-forward when the return is filed after the s.139(4) deadline. An updated return under s.139(8A) does not revive it.
5. Can an F&O loss be set off against capital gains in the same year?
Yes under the general cross-head set-off in s.71(1), subject to no specific bar. Because some practitioners take a stricter view, confirm with your CA before relying on it —.
6. I have both F&O loss and intraday equity profit. Can I set them off?
Yes — F&O loss can set off against intraday profit. F&O is non-speculative (proviso (d) to s.43(5)) but intraday equity trading is speculative (Explanation 2 to s.43(5) — settled otherwise than by actual delivery). A non-speculative loss (F&O) can set off against any business income, including a speculative profit. The reverse is NOT true: an intraday-equity LOSS is caged to speculation profits only under s.73(1), so it cannot touch an F&O profit.

Preserve the loss — file on time
If you have any F&O loss you may want to use later, file ITR-3 before the due date, even when no tax audit applies and your income is otherwise below the filing threshold. Use the F&O Turnover Calculator to compute turnover, then file on time — the 8-year carry-forward is worth more than any delay saves you.
