Finin2min Tax Desk·June 2026·7 min readLOSS SET-OFF

Losses can be valuable only if they are computed, reported and preserved correctly. For founders, the risk is not just losing money — it is losing the tax trail that would allow future set-off.

Losses need discipline

Official Income Tax Department material explains set-off and carry-forward of losses by income head. Business losses require proper computation, return filing and continuity of records to be useful in later years.
