What are the material participation tests?

Why the tests exist

A trade or business activity is not a passive activity if you materially participated in it, so a loss from it can reduce wages and other nonpassive income. Rental activities are the exception, since they are passive even with material participation unless you are a real estate professional. The test is applied activity by activity and year by year, and the burden of showing the hours falls on you, which is why the rules on proof matter as much as the tests themselves.

The seven tests

Meeting any one of these is enough:

1. You participated in the activity for more than 500 hours during the year.
2. Your participation was substantially all of the participation in the activity of all individuals for the year, including individuals who own no interest in it.
3. You participated for more than 100 hours and at least as much as any other individual, including non-owners.
4. The activity is a significant participation activity and your hours in all significant participation activities combined exceed 500. A significant participation activity is a trade or business in which you participated for more than 100 hours and did not materially participate under any of the other tests.
5. You materially participated, under any test other than this one, in any 5 of the 10 immediately preceding tax years, consecutive or not.
6. The activity is a personal service activity and you materially participated in it for any 3 preceding tax years, consecutive or not. Personal service means services in health (including veterinary), law, engineering, architecture, accounting, actuarial science, performing arts, consulting, or any other trade or business in which capital is not a material income-producing factor.
7. Based on all the facts and circumstances, you participated on a regular, continuous and substantial basis during the year.

Test 7 has its own limits. It is not met if you participated for 100 hours or less. And your management hours do not count under it if anyone else was paid to manage the activity, or if any individual spent more hours managing than you did, paid or not.

What counts as participation

In general, any work you do in connection with an activity in which you own an interest is participation. Two kinds of work are excluded. Work that is not customarily done by an owner of that type of activity does not count if one of your main reasons for doing it is to avoid the passive activity rules. And work you do as an investor does not count unless you are directly involved in day-to-day management or operations; investor work includes studying and reviewing financial statements, preparing summaries for your own use, and monitoring finances or operations in a nonmanagerial capacity.

Your spouse's participation is included with yours, even if the spouse owns no interest and you do not file jointly.

Proving your hours

The publication allows any reasonable method. You do not need contemporaneous daily time logs if you can show the services you performed and the approximate hours another way, for example from an appointment book, a calendar or a narrative summary. Reconstructed hours that are internally consistent with your other jobs tend to be more convincing than round numbers, but the publication sets no format.

Special cases

A limited partner generally does not materially participate, except by meeting test 1, 5 or 6, and you are not treated as a limited partner at all if you were also a general partner at all times during the partnership year. A retired or disabled farmer is treated as materially participating in farming if they materially participated in 5 or more of the 8 years before retirement or disability, and a farmer's surviving spouse qualifies when the real property meets the estate tax special valuation rules and they actively manage the farm. A closely held or personal service corporation is treated as materially participating only if one or more shareholders holding more than 50% by value materially participate.

A worked example

Imagine you run a landscaping business with two part-time employees. You work 320 hours, your spouse adds 40 hours, and the employee who worked most logged 600 hours. Together you and your spouse have 360 hours. Test 1 fails because 360 is not above 500. Test 2 fails because the employees did most of the work. Test 3 fails: 360 is above 100, but not at least as much as the 600-hour employee. Unless a prior-year test applies, only test 7 remains. It is a facts-and-circumstances call, and your management hours would not count toward it if an employee spent more hours managing the business than you did. On these numbers the activity is likely passive. Enter these figures above to see the result. This example is built from the rules, and the figures are made up for illustration.

Change one fact and the answer changes: if you and your spouse had worked 610 hours together, test 1 would be met regardless of what the employees did. And if you had materially participated in five of the previous ten years, test 5 would carry you through even in a slow year.

What follows from the result

If you do materially participate, report the income and loss on the usual schedules (Schedule C, Schedule F or Schedule E, Part II or III) and they stay out of Form 8582. If you do not, the activity is passive and the loss is limited by Form 8582 to passive income, unless another exception applies. Where you participated for more than 100 hours but still fell short, Publication 925 has a recharacterization rule for significant participation passive activities that can turn part of any net income into nonpassive income.
