Carry Forward of Losses
Carry forward of losses allows taxpayers to transport unabsorbed capital losses from the current financial year to subsequent years under Section 74, where they can be set off against future capital gains — LTCL for up to 8 years against LTCG only, and STCL for up to 8 years against both STCG and LTCG.
When capital losses in a financial year exceed capital gains, the unabsorbed excess cannot simply disappear — the Income Tax Act permits these losses to be carried forward for up to 8 assessment years. This provision gives investors a multi-year window to utilise losses from poor investment decisions against future profitable outcomes, thereby reducing the effective tax burden over the investment horizon.
The rules for carry-forward mirror those for set-off: long-term capital losses carried forward can only be set off against long-term capital gains in future years. Short-term capital losses carried forward can be set off against both short-term and long-term capital gains in future years. This asymmetry means that LTCL is a less flexible tax asset than STCL, and investors with large LTCL positions may need to ensure they generate sufficient LTCG in subsequent years to fully utilise the carried-forward loss before the 8-year window expires.
A mandatory precondition for carry-forward is filing the ITR before the due date under Section 139(1). If the ITR is filed late (i.e., as a belated return under Section 139(4) after the original due date), the carry-forward of capital losses is forfeited entirely — only the current year's set-off is permitted. This is one of the strongest incentives for timely ITR filing, especially for investors with significant realised losses.
Carried-forward losses are reflected in the ITR's Schedule CYLA (Current Year Loss Adjustment) and Schedule BFLA (Brought Forward Loss Adjustment), and subsequently tracked in Schedule CFL (Carry Forward of Losses). Each year, the taxpayer must proactively claim these in the ITR — they are not automatically applied by the income tax department. Reviewing carried-forward losses before ITR filing each year ensures no benefit is inadvertently lost.
For equity investors navigating multi-year market cycles, carried-forward losses can become significant. An investor who suffered heavy losses in a bear market (e.g., the COVID crash of 2020) and filed timely returns would have been able to carry forward those losses for up to 8 years — through assessment years ending in 2028 — and set them off against gains in the subsequent recovery. Disciplined record-keeping and timely filing are the two non-negotiable requirements for extracting this benefit.
