Passive Activity Loss Rules: Material Participation
When a loss is passive, the seven material participation tests, the $25,000 rental allowance, and the at-risk rules that apply first
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Under section 469's passive activity rules, a loss from a trade or business in which the taxpayer does not materially participate — or from a rental activity, passive by default — can be deducted only against income from other passive activities. Disallowed losses are suspended until there is passive income or the activity is sold. Seven tests define material participation.

What is a passive activity?
Two categories: any trade or business in which the taxpayer does not materially participate during the year, and any rental activity, regardless of participation (with two exceptions below). A limited partner's interest is generally passive. Working interests in oil and gas are excluded. Investment income (interest, dividends, capital gains on portfolio assets) is neither passive nor active — it is "portfolio" income, and passive losses cannot offset it either. The practical effect: a taxpayer with a US$40,000 loss from a rental property and US$200,000 of wages cannot deduct the loss against the wages unless an exception applies; the loss waits.
What are the seven material participation tests?
A taxpayer materially participates in an activity for the year if any one test is met:
| Test | Requirement |
|---|---|
| 1. 500 hours | More than 500 hours of participation during the year |
| 2. Substantially all | The taxpayer's participation was substantially all of the participation by anyone (including non-owners) |
| 3. 100 hours and not less | More than 100 hours, and not less than any other individual's participation |
| 4. Significant participation activities | The activity is a significant participation activity (more than 100 hours) and the taxpayer's total participation in all such activities exceeds 500 hours |
| 5. Five of ten years | The taxpayer materially participated in any five of the prior ten years |
| 6. Personal service activity | The activity is a personal service activity and the taxpayer materially participated in any three prior years |
| 7. Facts and circumstances | Regular, continuous, and substantial participation on all the facts — more than 100 hours, not counting management hours if anyone else is paid to manage or puts in more management hours |
Participation means work in the operations of the activity; investor-type activities (reviewing financials, monitoring) don't count unless the taxpayer is directly involved in day-to-day management. Contemporaneous records — calendars, logs, appointment books — are what prove hours; reconstructions after the fact are the losing position in most cases.
What are the rental exceptions?
The US$25,000 allowance: a taxpayer who actively participates in a rental real estate activity (a lower bar than material participation — making management decisions, approving tenants, arranging repairs) may deduct up to US$25,000 of rental losses against non-passive income, phased out by 50 cents per dollar of modified adjusted gross income above US$100,000 and gone at US$150,000 (not indexed; half these amounts for married taxpayers filing separately who lived apart all year, and nothing for those who lived together). The real estate professional exception: a taxpayer who spends more than 750 hours and more than half of all personal service time in real property trades or businesses in which they materially participate may treat rental activities as non-passive — with material participation then tested rental by rental, or in aggregate if the taxpayer elects to treat all rental real estate as a single activity. The exception is the reason cost segregation studies pay for full-time real estate operators and often don't for investors with day jobs (the cost segregation guide).
What happens to suspended losses?
They carry forward indefinitely, activity by activity, and are released in two ways: against passive income in any later year (from the same or any other passive activity), or in full when the taxpayer disposes of the entire interest in the activity in a fully taxable transaction to an unrelated party. Selling a rental property releases all of its suspended losses that year — often the year the taxpayer most needs them, against the gain on the sale. Suspended losses do not die with a passive activity that simply stops; they wait for the disposition.
Where do the at-risk rules come in?
Before the passive rules. Section 465 limits a taxpayer's deductible loss from an activity to the amount at risk — cash invested, the adjusted basis of property contributed, and amounts borrowed for which the taxpayer is personally liable or has pledged property (with qualified nonrecourse financing counted for real estate). A loss beyond the at-risk amount is suspended under section 465 (Form 6198) and never reaches the passive computation; a loss within it then faces the passive test (Form 8582), and then the excess business loss limitation. Three gates, in that order.
Worked example
A surgeon earning US$480,000 owns two rental duplexes managed by a property manager; after a cost segregation study, they show a US$70,000 combined loss. She does not materially participate (the manager does the work — test 2 fails, and her hours are under 100), so the activities are passive. Modified adjusted gross income is far above US$150,000, so the US$25,000 allowance is fully phased out. She is not a real estate professional (she cannot spend more than half her working time on real estate while practicing surgery). Result: the US$70,000 loss is suspended, carried forward on Form 8582. Three years later she sells one duplex at a US$140,000 gain: each duplex is a separate activity, so that property's suspended losses are released in full against the gain, and the other duplex's continue to wait. Her husband, who left his job to manage their properties full-time — 1,400 hours a year, all in real estate — qualifies as a real estate professional; with the election to treat all rental real estate as one activity, his material participation in the combined rental activity makes the losses non-passive, and they offset her surgical income.
Frequently asked questions
What is a passive activity?
A trade or business in which the taxpayer does not materially participate, or any rental activity regardless of participation (subject to the US$25,000 allowance and the real estate professional exception). Losses from passive activities offset only passive income.
What is material participation?
Regular, continuous, and substantial involvement in an activity's operations, established by meeting any one of seven tests — most commonly more than 500 hours in the year — with contemporaneous records proving the hours.
What is the $25,000 rental loss allowance?
A taxpayer who actively participates in rental real estate may deduct up to US$25,000 of rental losses against other income, phased out between US$100,000 and US$150,000 of modified adjusted gross income.
What are the at-risk rules?
Section 465's limit of a taxpayer's deductible loss to the amount actually at risk — cash and property invested plus personally liable debt — applied before the passive activity rules.
