Material Participation Tests

Key takeaways
* Material participation determines whether income or losses from a trade, business, rental, or other activity are treated as active (allowing full loss deduction subject to other limits) or passive (subject to passive loss limitations).
* A taxpayer (or spouse) meets material participation if they satisfy any one of seven IRS tests.
* Real estate rental activity is generally passive unless you qualify as a real estate professional.
* Keep contemporaneous records (logs, calendars, appointment books) to substantiate hours and types of work.

What material participation means

Material participation is participation in an income-producing activity that is regular, continuous, and substantial. If you materially participate, losses from the activity are treated as active and generally deductible (subject to at‑risk and other tax-code limits). If you fail to meet any material participation test, the activity is passive and passive loss rules limit your ability to deduct losses.

The seven IRS material participation tests

You qualify as materially participating for a tax year if you (or your spouse) satisfy any one of the following:

1. You worked more than 500 hours in the activity during the year.
2. Your participation constituted substantially all the participation in the activity by all individuals.
3. You worked more than 100 hours and no other individual worked more hours than you.
4. You participated in significant participation activities (SPAs) and your combined SPA hours exceed 500. (An SPA is any activity in which you participate more than 100 hours but that doesn’t meet the other tests.)
5. You materially participated in the activity for any five of the last 10 taxable years.
6. The activity is a personal service activity (e.g., health, law, engineering, accounting, performing arts, consulting) and you materially participated for any three prior tax years.
7. You worked more than 100 hours and, based on all facts and circumstances, your participation was regular, continuous, and substantial.

Limits and what doesn’t count

Not all time counts toward the 100- or 500-hour thresholds:
* Time spent as a passive investor generally doesn’t count unless you are directly involved in day‑to‑day management.
* Commuting time, work not customarily done by an owner, and time spent solely to avoid passive loss rules are excluded.
* Participation in purely managerial activities where other managers receive no compensation may not count.
* Reviewing market data (e.g., stock charts) ordinarily won’t qualify unless tied to substantial management involvement.

Special rules and common considerations

• Rental real estate: Generally passive even if you meet a material participation test — except if you qualify as a real estate professional under tax rules.
• Limited partners: Participation is usually passive unless you meet tests 1, 5, or 6.
• Multiple activities: If you participate in two enterprises run through the same passthrough entity, you must meet at least one test for each venture to be treated as materially participating in both.
• Aggregation: You may be able to aggregate similar activities in certain cases, but aggregation rules are specific and should be evaluated carefully.

Documenting participation

Maintain contemporaneous records to support your hours and tasks. Reasonable documentation includes:
* Appointment books, calendars, time logs
* Narrative summaries of work performed
* Correspondence, scheduling records, or other documents showing the nature and amount of participation

Tax impact

• Material participants: Losses are treated as active and may be deductible (subject to at-risk and other limitations).
• Passive participants: Losses are subject to the passive activity loss rules, which generally restrict deductibility until passive income is available or the activity is disposed of in a taxable transaction.

Practical advice

• Track hours and describe the work performed contemporaneously.
• Consider consulting a tax professional for complex situations (real estate professional status, multiple activities, or aggregation/qualifying questions).
