Set-Off and Carry Forward of Losses Under Income Tax: Rules, Time Limits, ITR

A loss in one year is not a wasted year if you set it off correctly. The Income Tax Act has a layered system: first you net within the same head, then across heads (subject to restrictions), and what remains rolls forward. The catch is that almost every benefit depends on filing the ITR on time and reporting losses in the right schedules. Miss the timing window or the schedule and the loss is gone, even if it is genuine.

This guide walks through the Sections 70 to 80 framework, the head-by-head rules, the time limits, and the ITR reporting that locks in the carry-forward right.

The Three-Layer Set-Off Structure

The Income Tax Act sets up loss treatment in three sequential steps:

1. Intra-head set-off (Section 70): A loss under any head of income is first set off against income under the same head in the same year. Example: business loss from one business set off against profit from another business.
2. Inter-head set-off (Section 71): Any unabsorbed loss after intra-head set-off can be adjusted against income under other heads in the same year, subject to specific restrictions.
3. Carry forward (Sections 72 to 79): Whatever remains can be carried forward to future assessment years for set-off against the same head of income, subject to time limits and conditions.

Each step has restrictions. The full picture for FY 2025-26 (AY 2026-27) is below.

Intra-Head Set-Off Rules

Income from Salaries

A salaried individual cannot have a loss under salary head; salary income is always positive.

Income from House Property

Loss from one house property can be set off against income from another house property without limit at the intra-head stage. Loss is most often interest-driven (Section 24(b)).

Profits and Gains of Business or Profession

Loss from one business can be set off against profit from another business. Speculative loss (intraday equity, etc.) is treated as a separate sub-head: it can only be set off against speculative profit. Specified business loss under Section 35AD can only be set off against specified business income.

Capital Gains

• Short-term capital loss can be set off against both short-term and long-term capital gain.
• Long-term capital loss can be set off only against long-term capital gain.

Income from Other Sources

Most losses can be set off, except a few:

• Loss from owning and maintaining race horses can be set off only against winnings from race horses.
• Loss from lottery, gambling, betting cannot be set off against any other income or loss.

Inter-Head Set-Off Rules (Same Year)

After intra-head set-off, residual losses can be set off against other heads, subject to restrictions:

The Rs 2 Lakh House Property Loss Cap

Section 71(3A) limits inter-head set-off of house property loss to Rs 2 lakh per year. This is the most consequential restriction for salaried homeowners with large home loan interest. Excess loss is carried forward.

For a worked example, see our Section 24(b) home loan guide.

Carry Forward of Losses

The timely-filing condition under Section 139(3) is critical: only house property loss and unabsorbed depreciation survive a belated return. All other carry-forward rights are forfeited.

Some Practical Scenarios

Scenario 1: Salaried Filer with Home Loan Loss

Rohit has FY 2025-26 figures:

• Salary: Rs 14,00,000.
• House property loss (interest paid Rs 4 lakh, no rent, self-occupied): Loss of Rs 2,00,000 (capped under Section 24(b) per the cap at the head level).

Wait, Section 24(b) caps interest deduction itself at Rs 2 lakh for self-occupied. So the house property loss is exactly Rs 2 lakh. Rohit can set off Rs 2 lakh against salary in FY 2025-26 (Section 71(3A) allows up to Rs 2 lakh inter-head). Net taxable salary becomes Rs 12,00,000. There is no carry-forward because the entire loss was absorbed.

If interest had been Rs 6 lakh on a let-out property (with no Section 24(b) cap):

• House property loss: Suppose Rs 4,50,000.
• Inter-head set-off against salary: Rs 2,00,000 only.
• Carry forward: Rs 2,50,000 to FY 2026-27, set off only against future house property income.

Scenario 2: F&O Trader Loss

Anjali has FY 2025-26 figures:

• Salary: Rs 12,00,000.

• F&O loss: Rs 5,00,000 (treated as non-speculative business under CBDT clarifications).

• Intraday equity loss: Rs 1,50,000 (speculative).

• F&O loss is non-speculative business loss. Cannot be set off against salary (Section 71(2) excludes salary). Carried forward for 8 years against business income only.

• Intraday loss is speculative. Cannot be set off against F&O profit (which is non-speculative). Carried forward for 4 years against speculative profit only.

• Anjali files ITR-3 (business income). Salary remains taxable at Rs 12,00,000. Both losses are carried forward, provided ITR is filed by 31 July 2026 (or 31 October if audited).

Scenario 3: Capital Loss

Vinay has FY 2025-26 figures:

• Short-term capital gain on equity: Rs 3,00,000.

• Long-term capital loss on equity: Rs 1,50,000.

• Salary: Rs 18,00,000.

• LTCL (Rs 1,50,000) cannot be set off against STCG. It can be set off only against long-term capital gain. Since there is no LTCG, the LTCL is carried forward for 8 years.

• STCG of Rs 3,00,000 is fully taxable (no offset).

If Vinay also had STCG of Rs 50,000 and STCL of Rs 80,000:

• STCL (Rs 80,000) intra-head against STCG (Rs 50,000) leaves Rs 30,000 STCL.
• The Rs 30,000 STCL can be set off against LTCG too (intra-head). With no LTCG this year, it is carried forward.

ITR Reporting in Schedule CFL

ITR-2 and ITR-3 contain a Schedule CFL (Carry Forward of Losses). This schedule has:

• Year-wise breakup of brought-forward losses (by AY).
• Set-off used during the current year.
• Balance carried forward.

The losses must have been reported in the Schedule CFL of the original ITR for the year of the loss. If you missed reporting a loss in the original return, you cannot magic it back into a future return.

For business loss, the Profit & Loss Schedule of ITR-3 should be reconciled with the Schedule CFL entries.

For capital loss, Schedule CG (Capital Gains) feeds into Schedule CFL.

Common Errors and How to Avoid Them

• Filing belated return and losing carry-forward. The most expensive mistake. File by the original due date if you have a loss to carry forward.
• Setting off capital loss against salary. Not allowed. Capital losses set off only against capital gains.
• Setting off long-term loss against short-term gain. LTCL is restricted to LTCG. The reverse is fine: STCL goes against STCG or LTCG.
• Setting off speculative loss against F&O profit. Speculative is intraday equity (and similar). F&O is non-speculative business. They are different sub-heads.
• Forgetting to report a loss in the original ITR. If you do not claim and report the loss in the original return for the year, it is not carriable forward. Even revised returns cannot rescue a loss not reported originally.
• House property loss cap of Rs 2 lakh per year. Excess is carried forward, not lost; but it must be reported in Schedule CFL.

Section 80 Restrictions on Set-Off

Section 80 reinforces that carry-forward business losses cannot be set off unless the return claiming the carry-forward right was filed within the Section 139(1) due date. Section 80AC similarly restricts certain Chapter VI-A deductions if return is filed after the due date.

Practically, this means: always file by the original due date if you have a loss to carry forward. The cost of late filing is far higher than the late filing fee under Section 234F; you may permanently lose the carry-forward benefit.

Action Plan

1. Identify each head's loss at the end of the financial year.
2. Apply intra-head set-off within each head before going inter-head.
3. Apply inter-head set-off within Section 71 limits, especially the Rs 2 lakh house property cap and the salary exclusion for business loss.
4. Determine carry-forward by category with the right time limit.
5. File ITR by the original Section 139(1) due date to preserve carry-forward rights.
6. Report losses correctly in Schedule CFL with year-wise breakup.
7. In future years, use Schedule CFL to claim set-off and reduce taxable income.

Where Tax Garden Helps

Loss tracking sounds like accounting plumbing but it sits at the heart of multi-year tax efficiency. Tax Garden's tax compliance services maintain a year-on-year loss register for our clients, ensure ITRs are filed by the original due date (so carry-forward rights are preserved), and report Schedule CFL accurately. We have seen taxpayers lose Rs 5 to 30 lakh of legitimate carry-forward rights through one belated filing.

Frequently Asked Questions

Can business loss be set off against salary income?

No. Section 71(2) specifically excludes salary as a head against which non-speculative business loss can be set off. Business loss can be carried forward for 8 years and set off only against business income in future years.

How long can I carry forward losses?

House property loss: 8 AYs. Non-speculative business loss: 8 AYs. Speculative business loss: 4 AYs. Specified business loss under Section 35AD: indefinite. Short-term and long-term capital loss: 8 AYs each. Race horse loss: 4 AYs. Unabsorbed depreciation: indefinite.

Can long-term capital loss be set off against short-term capital gain?

No. Long-term capital loss can be set off only against long-term capital gain. The opposite is allowed: short-term capital loss can be set off against both short-term and long-term capital gains.

Will I lose my carry-forward right if I file ITR late?

For most loss types, yes. Section 80 read with Section 139(3) requires the loss to be claimed in a return filed by the original due date. The exceptions are house property loss and unabsorbed depreciation, which survive a belated return.

How do I report carried-forward losses in my ITR?

Use Schedule CFL in ITR-2 or ITR-3. Report year-wise brought-forward losses, current year set-off, and balance carry-forward. The amounts must tie back to the loss reported in the Schedule CFL of the year in which the loss originally arose.

Is intraday trading loss treated the same as F&O loss?

No. Intraday equity is speculative business under Section 43(5). F&O on equities is non-speculative under the proviso to Section 43(5). They are separate sub-heads with different set-off rules and carry-forward windows.
