At-Risk & Passive Activity Rules

Why This Matters for the Exam

Loss limitations are heavily tested. The exam tests at-risk amounts, passive activity rules, and the rental real estate exception.

Expect at least 3-4 questions on loss limitations.

Loss Limitation Hierarchy

Losses face three sequential hurdles:

OrderLimitationRule
1BasisCannot exceed outside basis
2At-RiskCannot exceed at-risk amount
3Passive ActivityCannot offset active/portfolio income

At-Risk Rules

Partners can only deduct losses to extent they are at risk.

Included in At-RiskNot Included
Cash contributionsNonrecourse debt
Property basis contributedStop-loss arrangements
Recourse debt (personally liable)Guaranteed returns
Income allocatedProtection from loss

At-Risk Example

ItemAmount
Cash contributed$20,000
Share of nonrecourse debt$50,000
At-risk amount$20,000
Deductible loss limit$20,000

Passive Activity Basics

Income CategoryDescription
ActiveWages, SE income, material participation business
PassiveRental, business without material participation
PortfolioInterest, dividends, capital gains

Rule: Passive losses can ONLY offset passive income.

Material Participation Tests

A partner materially participates if they meet any of seven tests:

TestRequirement
1500+ hours during year
2Substantially all participation
3100+ hours, more than anyone else
4Significant participation (aggregate 500+)
5Materially participated 5 of last 10 years
6Personal service activity—3 prior years
7Facts and circumstances regular, continuous

$25,000 Rental Real Estate Exception

Active participants (lower standard) can deduct up to $25,000 of rental losses:

Real-World Scenario

Scenario: Partner contributes $20,000 cash. Partnership has $100,000 nonrecourse debt. Partner's share of loss is $50,000. Partner is a passive investor.

  • Basis limit: $20,000 + share of debt = varies.
  • At-risk limit: $20,000 (nonrecourse not included).
  • Deductible: $20,000 maximum.
  • Suspended: $30,000 (at-risk limitation).

On the Exam

Expect 3-4 questions on loss limitations, typically:

  1. At-Risk Questions: "What is the at-risk amount?"
  2. Passive Questions: "Can passive losses offset wages?"
  3. Rental Exception Questions: "What is the maximum rental loss deduction for AGI of $X?"

The key is to remember: At-risk = cash + recourse debt (not nonrecourse). Passive losses offset passive income only. Rental exception = $25,000, phase-out $100k-$150k.
