Set-Off and Carry Forward explained: this guide covers what Set-Off and Carry Forward means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
When income under one head is negative (a loss), the Income Tax Act 2025 allows the taxpayer to reduce that loss against positive income under other heads (inter-head set-off) or against income under the same head in the same or future years (carry forward). This guide explains the complete framework.
Step 1: Intra-Head Set-Off
Losses from one source under a head of income are first set off against positive income from another source within the same head. Example: Loss from one house property vs income from another house property in the same Tax Year.
Step 2: Inter-Head Set-Off (Same Year)
| Loss From | Can Set Off Against | Cannot Set Off Against |
|---|---|---|
| House Property | Any other head (max Rs. 2L) | Excess above Rs. 2L cannot be set off |
| Business/Profession (non-speculative) | Any other head except salary | Salary income |
| Speculative Business | Speculative Business only | All other heads |
| STCL | STCG, LTCG | Salary, business, HP |
| LTCL | LTCG only | STCG, all other heads |
| VDA Loss | Nothing | Cannot be set off anywhere |
Step 3: Carry Forward to Future Tax Years
| Loss Type | Carry Forward Period | Set Off Against |
|---|---|---|
| House Property Loss | 8 Tax Years | House property income only |
| Business Loss (non-speculative) | 8 Tax Years | Business income only |
| Speculative Business Loss | 4 Tax Years | Speculative profit only |
| STCL | 8 Tax Years | STCG or LTCG |
| LTCL | 8 Tax Years | LTCG only |
| Unabsorbed Depreciation | Indefinite | Any income |
| VDA Loss | Cannot carry forward | N/A |
Mandatory Return Filing to Carry Forward
A loss can be carried forward only if the ITR is filed by the due date (31 July for non-audit). If ITR is filed late (belated return), the right to carry forward most losses is lost. Exception: unabsorbed depreciation and house property losses can still be carried forward even with belated returns.
Important Conditions
- Continuity of business: Business loss carry forward requires 51% ownership continuity in companies (shareholder continuity test)
- Brought-forward losses are set off before current year losses in the same head
- Partner's share of firm loss can be carried forward by the partner personally
