Sources for Passive Activity and At-Risk Loss Limitations

Last reviewed 2026-10-06

The standards and authorities behind PocketCPA's TCP lessons on Passive Activity and At-Risk Loss Limitations. The topic rests on IRC Sec. 469, 465, 461(l).

About this topic

A partner's share of a partnership loss is not yet a deduction. It is a claim, and the claim has to clear four separate tests before it reaches the return. Each test asks a different question about the same dollar.

The subject is Sec. 465, Sec. 469 and Sec. 461(l), together with the basis limits in Sec. 704(d) and Sec. 1366(d) that run ahead of them. How outside basis is built and adjusted belongs to the partnership and S corporation material, not here.

Key points

Passive activity losses are deductible only against passive activity income; excess losses carry forward.
Material participation requires meeting one of seven tests, the most common being 500 hours of participation.
Rental activities are passive by default, with a $25,000 allowance for active participants phased out above $100,000 AGI.
The at-risk rules limit loss deductions to the amount the taxpayer has economically at stake.
