Our C corp lost money on securities but earned operating profit. Can the investment loss offset that profit?
A C corporation generally can deduct capital losses only against capital gains, subject to the corporate carryback and carryforward rules.

A C corporation generally can deduct capital losses only against capital gains, subject to the corporate carryback and carryforward rules. Ordinary operating profit does not by itself provide capacity to use a securities capital loss. This differs from the individual capital-loss allowance.
A specific business-owner situation
A corporation earns consulting profit but sells an investment portfolio at a capital loss. Applying the individual annual capital-loss rule on the corporate return would be incorrect.
Illustrative example, not a client result.
What to establish before filing
- Confirm the loss is capital.
- Identify current and eligible other-year capital gains.
- Track expiration and ownership-change limits.
Which fact changes the answer?
A loss on a capital investment differs from an ordinary business bad debt or qualifying ordinary asset loss. Character must be established first.
A mistake to avoid
Do not import individual capital-loss limits into a C-corporation calculation.
Records that support the decision
- Security sale records.
- Capital gain and loss schedules.
- Prior corporate returns.
The decision to document
Maintain a corporate capital-loss schedule and assess available carryback or carryforward use rather than offsetting operating income automatically.
