Business Loss Carry-Forward: Eight-Year Rule and Timely ITR
Reviewed by CA Nikhil Gupta · Last reviewed 2 August 2026
Ordinary non-speculative business loss can be carried forward for eight tax years and set off against future business/professional profit.
Timely filing is generally required to preserve carry-forward.

Legal or Computational Framework
Governing rule
Current-year business loss can be set off against eligible heads other than salary, subject to restrictions. Brought-forward business loss cannot be set off against salary or capital gains and is applied before unabsorbed depreciation.
Correct calculation method
Compute current loss; perform current-year set-off; file the loss return by the due date; maintain origin-year schedule; set off against future business profit before depreciation.
Step-by-step workflow
- Compute current loss.
- perform current-year set-off.
- file the loss return by the due date.
- maintain origin-year schedule.
- set off against future business profit before depreciation.
Worked example
Business loss ₹6 lakh and house-property income ₹2 lakh allow eligible current-year set-off, leaving ₹4 lakh to carry forward if the return is timely.
The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.
Why generic pages get this wrong
Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.
Decision matrix
| Decision point | Required treatment |
|---|---|
| Legal year | Use the Act, rules and notification effective for the income or transaction period |
| Taxpayer category | Confirm residence, age, entity, employee/business status and regime |
| Calculation base | Use the statutory definition rather than CTC, net bank receipt or accounting label |
| Ceiling or rate | Apply actual-amount, percentage, shared, lifetime and gross-income limits in sequence |
| Documentation | Link every input to an invoice, statement, contract, certificate or official record |
| Final output | Show tax, surcharge, cess, interest and TDS/TCS credits separately |
