Elvin thanks for the tax question.
Passive losses are limited when your income goes over a certain level.
The losses are not "lost" themselves. A passive loss is carried forward indefinitely until one of three events:
1) You have passive gains which the losses can offset
2) You sell the investment yielding the passive losses. This automatically releases all of the passive losses for this activity and you take the loss in the current tax year
3) Your income drops below the limiting threshold and releases some or all of the passive losses.
