Carry Forward and Set Off of Business and Capital Losses

Short answer: Setting off losses allows you to reduce your taxable income by adjusting losses from one source against income from another in the same financial year. If a loss cannot be fully set off, it can be carried forward to subsequent years (typically up to 8 years) to be set off against future income. To carry forward most losses, you must file your income tax return (ITR) by the due date.

What is the difference between set-off and carry forward of losses?

Set-off is the process of adjusting losses against profits in the same assessment year, while carry forward is the process of taking the unabsorbed losses to future assessment years. The Income Tax Act provides a clear hierarchy for this process. First, you attempt to set off a loss within the same head of income (intra-head, e.g., loss from one business against profit from another). If the loss persists, you can set it off against other heads of income (inter-head), subject to certain restrictions. Any remaining loss is then carried forward.

What are the rules for setting off business losses?

The rules depend on the nature of the business loss.

• Normal Business Loss (Non-Speculative): A loss from a regular business or profession can be set off against income from any other business, and then against any other head of income in the same year, except for salary income. Any unabsorbed loss can be carried forward for 8 assessment years and set off only against future income from business or profession.
• Speculative Business Loss: A loss from a speculative business (like intraday share trading) can only be set off against income from another speculative business. It cannot be set off against any other income. Unabsorbed speculative loss can be carried forward for 4 assessment years and set off only against future speculative business income.
• Specified Business Loss (Section 35AD): Losses from specified businesses (like building a hotel or a hospital in a rural area) can only be set off against profits from other specified businesses. There is no time limit to carry forward these losses.

How are capital losses treated?

Capital losses are categorised as either short-term or long-term, with different rules for each.

• Short-Term Capital Loss (STCL): A loss from the sale of an asset held for a short period can be set off against both Short-Term Capital Gains (STCG) and Long-Term Capital Gains (LTCG) in the same year.
• Long-Term Capital Loss (LTCL): A loss from the sale of an asset held for a long period can only be set off against Long-Term Capital Gains (LTCG). It cannot be set off against STCG or any other head of income.

Both unabsorbed STCL and LTCL can be carried forward for 8 assessment years. In future years, the carried-forward STCL can be set off against STCG or LTCG, while the carried-forward LTCL can only be set off against future LTCG.

Can I set off losses against my salary income?

No, you cannot set off any loss from business or profession against your salary income. Similarly, capital losses cannot be set off against salary. The only significant exception is a loss under the head 'Income from House Property'. You can set off a house property loss (arising mainly from home loan interest) against any other head of income, including salary, but this set-off is capped at ₹2,00,000 per assessment year. The unutilized loss can be carried forward for 8 years.

What is the time limit to carry forward losses?

The period for which you can carry forward different types of losses varies. Filing your income tax return by the due date specified under Section 139(1) is a mandatory condition for carrying forward most of these losses.

Type of Loss	Set-off in Same Year Against	Carry Forward & Set-off Against	Max. Period to Carry Forward	Must ITR be filed on time?
House Property Loss	Any head of income (capped at ₹2 Lakh for inter-head)	Income from House Property only	8 Years	No
Normal Business Loss	Any head of income (except Salary)	Income from Business/Profession only	8 Years	Yes
Speculative Business Loss	Speculative Business Income only	Speculative Business Income only	4 Years	Yes
Short-Term Capital Loss	STCG or LTCG	STCG or LTCG	8 Years	Yes
Long-Term Capital Loss	LTCG only	LTCG only	8 Years	Yes
Unabsorbed Depreciation	Any head of income (except Salary)	Any head of income (except Salary)	Indefinite	No

Is filing the ITR on time mandatory to carry forward losses?

Yes, absolutely. According to Section 139(3) read with Section 80 of the Income Tax Act, 1961, if you wish to carry forward a loss from 'Profits and Gains of Business or Profession' or 'Capital Gains', you must file your income tax return for the year of the loss on or before the due date. Filing a belated return under Section 139(4) will cause you to forfeit the right to carry forward these losses. However, this condition does not apply to carrying forward a loss from house property or unabsorbed depreciation.

Worked example

Let's consider Ms. Ananya, a software engineer in Bengaluru, for the Financial Year 2025-26 (Assessment Year 2026-27). She has income and losses from various sources and is under the new tax regime.

• Salary Income: ₹35,00,000
• Standard Deduction (New Regime): ₹75,000
• Loss from a boutique business (non-speculative): (₹4,00,000)
• Long-Term Capital Gain from property sale: ₹10,00,000
• Short-Term Capital Loss from shares: (₹2,50,000)
• Loss from House Property (interest on housing loan): (₹2,80,000)

Here is how her taxable income is calculated:

Step 1: Compute income under each head

• Income from Salary: ₹35,00,000 - ₹75,000 = ₹34,25,000
• Income from Business: (₹4,00,000)
• Capital Gains:
  • LTCG: ₹10,00,000
  • STCL: (₹2,50,000)
• Income from House Property: (₹2,80,000)

Step 2: Intra-head and Inter-head Set-off

1. Capital Gains: The STCL of ₹2,50,000 is set off against the LTCG of ₹10,00,000.
   • Remaining LTCG = ₹10,00,000 - ₹2,50,000 = ₹7,50,000.
2. House Property Loss: The loss of ₹2,80,000 can be set off against other income. Let's set it off against Salary. The maximum permissible set-off is ₹2,00,000.
   • Revised Salary Income = ₹34,25,000 - ₹2,00,000 = ₹32,25,000.
   • Remaining House Property Loss to carry forward = ₹2,80,000 - ₹2,00,000 = ₹80,000.
3. Business Loss: The loss of ₹4,00,000 cannot be set off against salary. It can be set off against the remaining LTCG.
   • Remaining LTCG after setting off business loss = ₹7,50,000 - ₹4,00,000 = ₹3,50,000.
   • Remaining Business Loss to carry forward = ₹0.

Step 3: Final Taxable Income Calculation

• Income from Salary: ₹32,25,000
• Income from Business: ₹0
• Capital Gains: ₹3,50,000
• Income from House Property: ₹0
• Gross Total Income: ₹32,25,000 + ₹3,50,000 = ₹35,75,000

Step 4: Losses to be Carried Forward

• House Property Loss: ₹80,000 (can be carried forward for 8 years).
• Business/Capital Loss: Nil.

This must be reported in her ITR (likely ITR-2) filed before the due date to ensure the house property loss is correctly carried forward.

Common mistakes

1. Filing ITR after the due date: This is the most common error, leading to the inability to carry forward business and capital losses. A belated return nullifies this crucial tax benefit.
2. Incorrectly setting off losses: Trying to set off business losses against salary, or a long-term capital loss against short-term capital gains, are frequent mistakes that lead to defective returns and tax notices.
3. Forgetting to claim brought-forward losses: Taxpayers often forget to fill the 'Schedule CFL' (Carry Forward Loss) in their ITR, thereby failing to reduce their tax liability in the current year.
4. Mixing speculative and non-speculative losses: Setting off intraday trading loss against income from a regular business is not permitted and will be disallowed.
5. Not maintaining proper records: Without proper books of accounts, proving the genuineness of a business loss during scrutiny can become impossible.

Frequently asked questions

H3: What happens to losses if I don't have enough income to set them off in a year?

If your losses for a year exceed your income, or if you have a net loss after all possible set-offs, the remaining unabsorbed loss is carried forward to the next assessment year, subject to the specific rules and time limits for that type of loss.

H3: Can I carry forward a loss from a business that has been shut down?

The loss belongs to the assessee (the taxpayer), not the business entity itself. Therefore, even if the business from which the loss arose has been discontinued, you can still carry forward that loss and set it off against profits from any other new or existing business you might have in future years.

H3: Is there a monetary limit on how much loss can be set off?

Yes, for inter-head adjustments, the loss from House Property that can be set off against other income heads is capped at ₹2,00,000 per year. There is no such monetary cap for setting off business losses against other business income or capital gains, but the rules of which loss can be set off against which income must be followed.

H3: How is unabsorbed depreciation different from a business loss?

Unabsorbed depreciation is the portion of the depreciation allowance that could not be claimed in a year due to insufficient business profits. Unlike a business loss, unabsorbed depreciation can be carried forward indefinitely. Also, the requirement of filing the ITR by the due date does not apply for carrying forward unabsorbed depreciation.

H3: Do the rules for carry forward and set-off of losses apply under the new tax regime?

Yes, the rules and procedures for setting off and carrying forward losses from business, capital gains, and house property are generally the same for taxpayers who opt for the new tax regime (Section 115BAC) or stay with the old one. Read our guide on the new vs. old tax regime for more details.
