Passive rental losses are suspended as a result of not having "passive income", not having active participation, or "actively participating" in the activity, but having modified adjusted gross income in excess of $150,000 (does not include filing status of married filing separate.)
Suspended passive losses are carried forward until they can either be offset with passive income, modified adjusted gross income decreases provided there is "active participation", or the activity is disposed of.
Accordingly, in order to utilize these suspended losses, the client would need to invest in an activity that produces "passive income", or just "sit tight" and utilize them upon final disposition or sale of 100% of the interest in the activity.
