What are the material participation tests?

    Depends on your hours and the activity

    Temp. Treas. Reg. §1.469-5T(a) lists seven tests. Meeting any one means you materially participate, so a business activity's losses are nonpassive. The most used are more than 500 hours, substantially all of the participation, or more than 100 hours and not less than anyone else. Rental activities remain passive under IRC §469(c)(2) unless you qualify as a real estate professional or the activity is not a rental activity under the regulations.

    Key takeaways

    • Material participation is tested for each activity, each year.
    • (a)(1) more than 500 hours; (a)(2) substantially all participation; (a)(3) more than 100 hours and not less than any other individual.
    • Hours of employees, contractors, and managers count when comparing participation.
    • Investor-type work generally does not count unless you are directly involved in day-to-day management or operations.
    • Passing a test does not make an ordinary long-term rental nonpassive by itself.

    What it is

    The passive activity rules in IRC §469 separate income and losses into passive and nonpassive groups. A trade or business in which you do not materially participate is passive, and its losses generally offset only passive income. Material participation means being involved in the operations on a regular, continuous, and substantial basis, and the regulations turn that standard into seven tests.

    The tests matter most for owners of businesses they do not run full-time, such as a franchise, a partnership interest, or a side business, and for short-term rentals and real estate professionals.

    What the law says

    IRC §469(h)(1) says a taxpayer materially participates only if involved in operations on a regular, continuous, and substantial basis. IRC §469(c)(2) treats rental activity as passive except as provided in §469(c)(7). Temp. Treas. Reg. §1.469-5T(a) provides that an individual materially participates if and only if the individual meets one of seven tests.

    The tests are: (a)(1) more than 500 hours; (a)(2) substantially all of the participation of all individuals; (a)(3) more than 100 hours and not less than any other individual; (a)(4) significant participation activities totaling more than 500 hours; (a)(5) material participation in any 5 of the preceding 10 years; (a)(6) a personal service activity with material participation in any 3 prior years; and (a)(7) a facts-and-circumstances test requiring more than 100 hours.

    Requirements and tests

    When applying the tests, keep these rules in mind:

    • Work counts if it is work an owner would customarily do; investor-type work such as reviewing statements does not, unless you are directly involved in day-to-day management or operations.
    • Your spouse's participation counts as yours, even if the spouse has no ownership interest.
    • For the (a)(2) and (a)(3) tests, the hours of every individual, including employees and property managers, are compared with yours.
    • Under the (a)(7) test, time spent managing the activity does not count if anyone else is paid to manage it or if another individual spends more hours managing it.
    • Limited partners generally can use only the (a)(1), (a)(5), and (a)(6) tests.
    • You may prove participation by any reasonable means, but contemporaneous logs are the strongest evidence.

    How it works

    Define the activity first, including any grouping of activities under Treas. Reg. §1.469-4. Then add up the hours you and your spouse spent on qualifying work during the year and compare them with the tests and with other people's hours. If any test is met, the activity is nonpassive for that year: losses can offset other income, subject to basis, at-risk, and excess business loss limits, and income from the activity is not passive income.

    Grouping matters. If you group two businesses as one activity, hours in either count toward the combined activity, which can help you meet a test. The grouping must be an appropriate economic unit, must be disclosed under Rev. Proc. 2010-13, and generally cannot be changed later unless the original grouping was clearly inappropriate or circumstances change materially. Rental and nonrental activities generally cannot be grouped unless one is insubstantial relative to the other or ownership is identical.

    For a rental activity, passing a test is not enough by itself. The rental remains passive unless you are a real estate professional under IRC §469(c)(7) or the activity is excluded from the definition of rental activity, for example because the average customer use is seven days or less.

    A $60,000 loss from a franchise business

    Assumptions: Tax year 2026; married filing jointly; the owner holds a 50% LLC interest in a franchise restaurant (not a rental activity).; The owner's share of the 2026 loss is $60,000; basis, at-risk, and excess business loss limits are met.; No passive income from other activities; tests (a)(4) through (a)(7) are not met.

    Scenario 1: owner and spouse hours / general manager hours150 / 2,000
    Scenario 1: (a)(1), (a)(2), (a)(3) met?No; manager participated more
    Scenario 1: loss deductible in 2026$0; suspended
    Scenario 2: owner and spouse hours520
    Scenario 2: (a)(1) more than 500 hours met?Yes
    Scenario 2: loss deductible against other income in 2026$60,000

    With 520 documented hours, the $60,000 loss is nonpassive; with 150 hours and a busier manager, it is suspended until the owner has passive income or disposes of the interest.

    Illustration only; not a projection of your results.

    Risks and IRS scrutiny

    Examiners test hour claims against other evidence, such as employment, travel, and the hours of managers and staff. Reconstructed logs, round-number estimates, and time that is really investor activity are common reasons claims fail. If material participation is denied, losses are suspended, and an accuracy-related penalty may apply.

    Material participation is only one part of the passive-activity framework. Suspended losses remain limited until there is passive income or a qualifying complete disposition, and basis, at-risk, and excess-business-loss limits can apply before a loss reaches the return. Rental owners should also review active participation, real-estate-professional rules, short-term-rental exceptions, grouping elections, and the release of suspended losses.

    Also note that material participation can cut the other way: income from an activity in which you materially participate cannot be used to absorb passive losses from other activities.

    Who it is not for

    These tests usually will not help passive investors who rely on a manager, owners whose involvement is limited to financial oversight, or owners of long-term rentals who do not qualify as real estate professionals. They also do not fit anyone unwilling to keep a detailed time record throughout the year.

    Frequently asked questions

    Is the 100-hour test enough for material participation?

    Only if your participation is also not less than that of any other individual, including employees and managers. Spending 100 hours alone is not enough.

    Does material participation make my rental losses nonpassive?

    Not for an ordinary long-term rental. Rental activity is passive unless you qualify as a real estate professional or the activity is not a rental activity, such as one with average stays of seven days or less.

    Do my spouse's hours count for material participation?

    Yes. A spouse's participation is treated as yours for the material participation tests, even if the spouse does not own an interest.

    How do I prove hours for material participation?

    Keep a contemporaneous log of dates, tasks, and time, supported by calendars, messages, and invoices. Estimates made after the fact are often rejected.
