Passive Loss Limits, At-Risk Rules, and K-1 Layering

This chapter covers the limitation systems that often block a taxpayer from using a loss immediately. TCP questions here usually require you to determine the activity classification, apply the limitation order correctly, and identify what happens to disallowed amounts.

In This Chapter

• Material Participation and Passive Income explains how activities are classified as passive or nonpassive.
• Suspended Losses and Real Estate Exceptions covers carryforward rules and the main real-estate relief provisions.
• Passive Losses and At-Risk Limitations shows how the two limitation systems interact.
• K-1 Layering for Passive and Active Activities applies the rules to flow-through entity allocations.

How to Use This Chapter

• Read this chapter when you can compute the loss but not determine whether it is usable.
• Focus on classification, ordering, and carryforward treatment.
• Revisit it whenever K-1 items, real-estate exceptions, or at-risk amounts drive the answer.
