EA Part 2 At-Risk Rules and Passive Activity Losses for Business Owners
At-risk and passive activity rules limit business loss deductions. Learn how they apply to S-corps, partnerships, and rental activities on Part 2.
June 12, 2025
Two overlapping limitations govern how much of a business loss a taxpayer can deduct in a given year: the at-risk rules of Section 465 and the passive activity loss (PAL) rules of Section 469. Part 2 tests both, and the exam rewards candidates who can apply each rule independently and then track their interaction. Think of them as two separate filters a loss must pass through before it becomes deductible.
At-Risk Rules: Section 465
The at-risk rules limit a taxpayer's loss deduction to the amount the taxpayer has "at risk" in the activity. The policy rationale: Congress wanted to prevent taxpayers from deducting losses larger than their actual economic exposure.
What Creates At-Risk Basis
A taxpayer is considered at risk for:
- Cash contributed and the adjusted basis of other property contributed
- Recourse debt: Amounts borrowed for which the taxpayer is personally liable, meaning creditors can pursue the taxpayer's personal assets if the business cannot repay
- Qualified nonrecourse financing: A specific type of nonrecourse debt available only for real property held for rental — specifically, financing from a commercial lender (not a related party) and not convertible debt
Notably, nonrecourse liabilities other than qualified nonrecourse financing do not increase at-risk basis. A limited partner who contributes $10,000 and the partnership takes on $500,000 of nonrecourse debt (other than QNF) has only $10,000 at risk.
Effect of the At-Risk Limitation
Losses in excess of at-risk basis are suspended and carried forward to future years. They become deductible when the taxpayer's at-risk amount increases — through additional contributions, assumption of recourse debt, or income allocations — or when the taxpayer disposes of the activity in a fully taxable transaction.
The at-risk rules apply at the individual activity level for most activities. At-risk amounts and suspended losses are tracked separately for each activity.
Passive Activity Loss Rules: Section 469
Even if a loss passes the at-risk test, the passive activity loss rules may suspend it further. The PAL rules prevent taxpayers from using losses from activities in which they do not materially participate to offset salary, interest, dividends, and other non-passive income.
Defining a Passive Activity
A passive activity is any trade or business in which the taxpayer does not materially participate. Rental activities are automatically passive regardless of participation, with one major exception (discussed below for real estate professionals).
Passive income and passive losses are netted against each other across all passive activities. Net passive losses are suspended; net passive income is taxable currently.
Material Participation: The Seven Tests
A taxpayer materially participates in an activity for the tax year if any one of the following seven tests is met:
- The taxpayer participated more than 500 hours during the year
- The taxpayer's participation was substantially all of the participation by all individuals (including non-owners)
- The taxpayer participated more than 100 hours and no other individual participated more
- The activity is a significant participation activity (SPA) — more than 100 hours but less than 500 — and the total of all SPA hours exceeds 500 for the year
- The taxpayer materially participated in the activity for any 5 of the prior 10 tax years
- The activity is a personal service activity and the taxpayer materially participated in any 3 prior tax years
- Based on all facts and circumstances, the taxpayer participated on a regular, continuous, and substantial basis (this catch-all requires more than 100 hours)
Tests 1 and 3 are the most frequently tested on Part 2. Know the 500-hour and 100-hour thresholds cold.
Rental Activities
Rental activities are presumptively passive regardless of participation hours. Two exceptions apply:
Real estate professionals: A taxpayer qualifies as a real estate professional if more than 50% of personal services performed during the year are in real property trades or businesses in which the taxpayer materially participates, and the taxpayer performs more than 750 hours of services in those businesses. A qualifying real estate professional's rental activities are treated as non-passive if the taxpayer materially participates in each rental activity (or makes a grouping election).
$25,000 rental allowance: Taxpayers who actively participate (a lower standard than material participation — essentially making management decisions) in rental real estate may deduct up to $25,000 of net rental losses against non-passive income. This allowance phases out at a rate of 50 cents per dollar of adjusted gross income between $100,000 and $150,000 (completely phased out at $150,000 AGI).
Grouping Elections
Taxpayers may group multiple activities into a single activity for purposes of applying the material participation tests. Grouping is appropriate when activities form an appropriate economic unit based on factors like geographic location, similarity of products, and common ownership. A grouping election is binding in subsequent years unless there is a material change in circumstances.
Interaction of At-Risk and PAL Rules
The two rules operate sequentially:
- At-risk test first: Apply Section 465. If the loss exceeds at-risk basis, the excess is suspended under the at-risk rules and cannot be considered further.
- PAL test second: Apply Section 469 to any loss that survives the at-risk test. If the activity is passive and there is insufficient passive income to absorb the loss, the remaining loss is suspended under the PAL rules.
A loss can be suspended by both rules simultaneously. Restoring at-risk basis releases the loss to the next filter; having sufficient passive income (or disposing of the activity) releases PAL-suspended losses.
Suspended Losses on Disposition
When a taxpayer disposes of an entire passive activity in a fully taxable transaction, all suspended losses from that activity are released and become deductible against any type of income — passive, active, or portfolio. This is the only way to unlock PAL-suspended losses against ordinary income without generating passive income from other sources.
