Losses in income tax are not just a setback - they are a tax asset if managed correctly. The Income Tax Act allows you to "set off" losses against income to reduce your tax liability, and "carry forward" unadjusted losses to future years. But the rules vary dramatically by loss type: which head it arose from, which income it can be adjusted against, how many years it can be carried forward, and whether timely filing is required.
This guide provides the complete set-off and carry forward framework for AY 2026-27, with the master set-off matrix, carry forward summary table, worked examples, and the ITA 2025 transition rules for pre-2026 losses.
How Set-Off Works: Two Levels
Level 1: Intra-Head Set-Off (Section 70)
Loss from one source can be set off against income from another source under the same head. Example: loss from Business A can be set off against profit from Business B (both under "Profits and Gains of Business or Profession"). Short-term capital loss on equity can be set off against long-term capital gain on property (both under "Capital Gains").
Level 2: Inter-Head Set-Off (Section 71)
If losses remain after intra-head adjustment, they can be set off against income under other heads - with specific restrictions. Example: business loss (after intra-head) can be set off against salary income. But capital losses can NEVER be set off against other heads.
For individuals managing income tax return filing, correctly applying the set-off order maximises deductions and minimises tax liability.
Master Set-Off Matrix: What Can Be Adjusted Against What
| Loss Head | Salary | House Property | Business/Profession | Capital Gains | Other Sources |
|---|---|---|---|---|---|
| House Property loss (up to Rs 2L) | Yes | Yes | Yes | Yes | Yes |
| House Property loss (above Rs 2L) | No | Carry forward only | No | No | No |
| Business loss (non-speculative) | Yes | Yes | Yes (intra-head first) | Yes | Yes (except casual income) |
| Speculative business loss | No | No | Only speculative income | No | No |
| Specified business loss (Sec 35AD) | No | No | Only specified business income | No | No |
| Short-term capital loss | No | No | No | STCG + LTCG | No |
| Long-term capital loss | No | No | No | LTCG only | No |
| Loss from owning race horses | No | No | No | No | Only race horse income |
| Other Sources loss | Yes | Yes | Yes | Yes | Yes (intra-head) |
Key restrictions: (1) Capital losses can NEVER set off against any head except capital gains. (2) Speculative loss can only set off against speculative income. (3) House property loss is capped at Rs 2 lakh for inter-head set-off. (4) No loss can be set off against casual income (lottery, crossword, etc.). (5) Salary head has no loss - it is always positive.
Carry Forward Summary: Complete Reference Table
| Loss Type | Section (1961) | Section (ITA 2025) | Carry Forward Period | Set Off Against | Due Date Filing Required? |
|---|---|---|---|---|---|
| House Property loss | 71B | 110 | 8 AY | House Property income only | No - can carry forward even with late return |
| Business loss (non-speculative) | 72 | 112 | 8 AY | Business income only (any business) | Yes - must file by Section 139(1) due date |
| Speculative business loss | 73 | 113 | 4 AY | Speculative business income only | Yes |
| Specified business loss (35AD) | 73A | 114 | Unlimited | Specified business income only | Yes |
| Short-term capital loss | 74 | 111 | 8 AY | STCG + LTCG | Yes |
| Long-term capital loss | 74 | 111 | 8 AY | LTCG only | Yes |
| Loss from race horses | 74A | 115 | 4 AY | Race horse income only | Yes |
| Unabsorbed depreciation | 32(2) | Corresponding provision | Unlimited | Any income except salary and casual income | No - automatic carry forward |
Professional tax planning services can optimise the set-off order to minimise current year tax while preserving maximum carry forward for future years.
The Due Date Filing Mandate
Section 80 of the Income Tax Act states that the following losses can be carried forward only if the ITR is filed on or before the due date under Section 139(1):
- Business loss (non-speculative) - Section 72
- Speculative business loss - Section 73
- Short-term capital loss - Section 74
- Long-term capital loss - Section 74
- Loss from specified business - Section 73A
- Loss from race horses - Section 74A
Exception: House property loss (Section 71B) and unabsorbed depreciation (Section 32(2)) can be carried forward even if the return is filed late. This is why filing by the due date is critical for business owners and investors - a late return permanently destroys the carry forward right for these losses.
For investors with capital losses, filing by 31 July 2026 (ITR-1/2) or 31 August 2026 (ITR-3/4 non-audit) is non-negotiable. Refer to ITR for capital gains for due date details and capital loss reporting.
Worked Examples
Example 1: Business Loss Set Off Against Salary
Mr. Raj - Salary: Rs 10 lakh. Business loss (non-speculative): Rs 3 lakh.
Intra-head: No other business income to set off against.
Inter-head: Rs 3 lakh business loss set off against Rs 10 lakh salary under Section 71. Taxable income = Rs 7 lakh.
Result: Tax saved at 20% slab (old regime) = approximately Rs 62,400 (including cess). If Raj had filed late, the Rs 3 lakh loss could NOT be carried forward - but current year inter-head set-off is still allowed even with a late return. For business income/loss reporting, refer to ITR for business.
Example 2: Capital Loss - STCL Against LTCG
Mrs. Priya - STCL on equity: Rs 1,50,000. LTCG on property: Rs 5,00,000.
Intra-head: STCL Rs 1,50,000 set off against LTCG Rs 5,00,000 under Section 70. Net capital gains = Rs 3,50,000.
Result: STCL can set off against LTCG (short-term loss is flexible). But LTCL could NOT set off against STCG (long-term loss is restrictive). Tax saved on Rs 1,50,000 at 12.5% LTCG rate = Rs 19,500 approximately.
Example 3: House Property Loss - Rs 2 Lakh Cap
Mr. Vikram - Salary: Rs 15 lakh. House property loss (self-occupied, interest on loan): Rs 3,50,000.
Inter-head: Rs 2,00,000 set off against salary (Section 71 cap). Remaining Rs 1,50,000 carried forward under Section 71B for 8 years - can set off only against future house property income.
Result: Even though the full loss is Rs 3,50,000, only Rs 2 lakh reduces current year taxable income. The balance is preserved but restricted to house property income in future years.
Example 4: Carry Forward - Business Loss Over Multiple Years
Mr. Suresh - AY 2023-24: Business loss Rs 5 lakh (carried forward). AY 2024-25: Business income Rs 2 lakh. AY 2025-26: Business income Rs 4 lakh.
AY 2024-25: Set off Rs 2 lakh of brought-forward loss against Rs 2 lakh business income. Remaining carry forward: Rs 3 lakh.
AY 2025-26: Set off Rs 3 lakh against Rs 4 lakh business income. Taxable business income: Rs 1 lakh. Carry forward exhausted.
Note: Carried-forward business loss can ONLY set off against business income - not salary or other heads. This is different from current-year business loss which can set off inter-head.
Example 5: Late Filing Destroys Carry Forward
Ms. Kavitha - STCL: Rs 2 lakh on equity. Filed ITR on 15 September 2026 (after 31 July due date). No other capital gains in the year.
Result: Rs 2 lakh STCL is permanently lost. Section 80 mandates that capital losses can be carried forward only if ITR is filed by the due date. Since Kavitha filed late, she cannot carry forward this loss to future years. This Rs 2 lakh could have saved Rs 30,000+ in future STCG tax over 8 years.
Budget 2025 Change: Capital Loss Relaxation (Until 31 March 2026)
Budget 2025 introduced a temporary relaxation for capital losses incurred up to 31 March 2026: long-term capital losses can be set off against any type of capital gain - both STCG and LTCG. Under normal rules, LTCL can only adjust against LTCG. This one-time flexibility applies only for losses incurred until FY 2025-26. From FY 2026-27 (Tax Year 2026-27), the standard restrictive rules resume.
ITA 2025 Transition: How Pre-2026 Losses Are Treated
| Pre-2026 Loss Type | Carry Forward Under New Act? | Set Off Rules | Governing Provision |
|---|---|---|---|
| House property loss (pre-April 2026) | Yes - preserved | Set off per old Section 71B rules | Section 536 of ITA 2025 |
| Business loss (pre-April 2026) | Yes - preserved | Set off against business income per old Section 72 | Section 536 |
| Capital losses (pre-April 2026) | Yes - preserved | STCL vs STCG/LTCG, LTCL vs LTCG per old Section 74 | Section 536 |
| Unabsorbed depreciation (pre-April 2026) | Yes - preserved | Set off per old Section 32(2) - any income except salary/casual | Section 536 |
| Speculative loss (pre-April 2026) | Yes - preserved | Against speculative income per old Section 73 | Section 536 |
Key principle: Section 536 of ITA 2025 (repeal and savings clause) preserves the original character and set-off rules of all pre-2026 losses. They are not reclassified under the new Act. The new Act's sections (108-121) govern new losses from Tax Year 2026-27 onwards.
Common Mistakes to Avoid
Mistake 1: Trying to set off capital loss against salary or other heads. Capital losses (STCL and LTCL) can ONLY be set off against capital gains - never against salary, business income, or other sources. This is the most common error in ITR filing.
Mistake 2: Filing ITR late when you have carry-forward losses. Section 80 mandates due-date filing for carry forward of business, speculative, capital, and specified business losses. A single day of delay permanently destroys years of carry-forward potential. House property loss and unabsorbed depreciation are the only exceptions.
Mistake 3: Not claiming current-year inter-head set-off. Current-year business loss can set off against salary and other heads (Section 71). Many taxpayers forget this - they only report business loss in Schedule BP without letting it flow to Schedule CYLA (Current Year Losses Adjustments). Ensure TDS return filing reconciliation is complete so that the net loss computation is accurate.
Mistake 4: Confusing current-year and brought-forward set-off rules. Current-year business loss → inter-head (against any head except casual income). Brought-forward business loss → ONLY against business income. The rules change once the loss is carried forward.
Mistake 5: Exceeding Rs 2 lakh house property loss cap for inter-head. Only Rs 2 lakh of house property loss can be adjusted against other heads in the current year. The excess is carried forward but restricted to house property income only. Claiming more than Rs 2 lakh inter-head will trigger 143(1) adjustment.
Order of Set-Off: Recommended Sequence
- Step 1: Compute income under each head separately (Salary, House Property, Business, Capital Gains, Other Sources)
- Step 2: Apply intra-head set-off (Section 70) - loss from one source against income from another source within the same head
- Step 3: Apply inter-head set-off (Section 71) - remaining loss against income from other heads (subject to restrictions)
- Step 4: Set off brought-forward losses against eligible current-year income (Section 72, 73, 74, 71B)
- Step 5: Set off unabsorbed depreciation against any income except salary and casual income (Section 32(2))
- Step 6: Compute Gross Total Income after all set-offs → apply deductions (Chapter VI-A) → arrive at Total Income
Key Takeaways
Set-off has two levels: intra-head (Section 70 - within the same head) and inter-head (Section 71 - across different heads). Capital losses can NEVER be set off inter-head. House property loss is capped at Rs 2 lakh for inter-head. Speculative loss is restricted to speculative income only.
Carry forward periods: business loss 8 years, capital loss 8 years, speculative loss 4 years, house property loss 8 years, unabsorbed depreciation unlimited. Section 80 mandates due-date filing for carry forward of all losses except house property and unabsorbed depreciation.
Current-year business loss can set off against any head (including salary). But brought-forward business loss can ONLY set off against business income. The inter-head flexibility is lost once the loss is carried forward.
Budget 2025 introduced a temporary relaxation allowing LTCL to set off against any capital gain (STCG or LTCG) for losses incurred until 31 March 2026. Standard restrictive rules resume from Tax Year 2026-27.
Under ITA 2025, pre-2026 losses are preserved in their original character and carry forward under old Act rules via Section 536 (repeal and savings). New losses from Tax Year 2026-27 follow Sections 108-121 of the new Act.
