Realized vs Recognized Gain: Why Can the Numbers Be Different?
Realized gain measures the economic gain in the transaction. Recognized gain measures how much enters taxable income now.
Realized gain
A common framework is amount realized minus adjusted basis. This measures the economic gain or loss from the disposition.
Recognized gain
Recognized gain is the portion currently included in taxable income after applying the relevant tax rules.
Why they differ
Nonrecognition provisions such as qualifying exchanges, formations, or reorganizations can defer part or all of a realized gain.
Deferred does not mean erased
When gain is not recognized immediately, basis rules often preserve the deferred gain for a future taxable event.
The takeaway
Calculate realized gain first. Then apply any nonrecognition rule to determine recognized gain.
