Rental losses, real estate professional status and the short-term rental rule (US federal)

Figures are for tax year 2026. This Guide covers the federal passive activity rules in section 469 of the Internal Revenue Code as they apply to an individual who owns rental property: why a rental loss is usually stuck, the active participation allowance, real estate professional status, material participation, and the short-term rental rule. It is written for a high-earning employee or business owner who owns or plans to buy rentals, and for their adviser. It does not cover state tax. Statute text is cited from the LII mirror of the U.S. Code (law.cornell.edu); regulations from ecfr.gov; forms from irs.gov. The IRS form instructions and Pub. 925 cited here are the 2025 editions, the latest on irs.gov when this Guide was written; the statutory rules they describe are not indexed and did not change for 2026. All worked examples are hypothetical.

The method, step by step

1. Classify each property for the year. Work out the average period of customer use under Reg. § 1.469-1(e)(3)(iii) and test the exceptions in Reg. § 1.469-1T(e)(3)(ii). Note the result (rental activity, or not a rental activity because an exception applies) and go to step 2 either way.
2. Check personal use of any dwelling under § 280A(d)(1), whether or not the property is a rental activity. If the owner used it as a residence, § 280A(c)(5) caps the deductions from the rental use at the gross rental income less the deductions allowable anyway, whatever the section 469 result, and for a passive activity § 469(j)(10) leaves the items from that use out of section 469: stop here for that unit. Otherwise a rental activity goes to step 3 and a property that is not a rental activity goes to step 5.
3. Test real estate professional status for the year under § 469(c)(7)(B) and Reg. § 1.469-9(c), one spouse at a time. If no one qualifies, every rental real estate activity is passive: go to step 4. If someone qualifies, test material participation in each rental real estate interest, or in the single combined activity if the election in Reg. § 1.469-9(g) is in force or is being made. A rental in which the qualifying taxpayer materially participates is not passive.
4. For passive rental real estate, test active participation and apply the special allowance and its phase-out under § 469(i). Run the passive loss computation on Form 8582 (Instructions for Form 8582). Carry any disallowed loss forward to the next year under § 469(b).
5. For a property that is not a rental activity, decide whether it is a trade or business activity and whether the owner materially participated under Reg. § 1.469-5T(a). With material participation, report the income or loss on the usual forms, not on Form 8582. Without it, the activity is passive and goes on Form 8582 (Instructions for Form 8582).
6. Apply the limits in order. The IRS instructions put basis and at-risk limits first, then the passive loss limits, then the excess business loss limit on Form 461 (Instructions for Form 8582).
7. On a sale, check whether it is a fully taxable disposition of the entire interest in the activity to an unrelated party under § 469(g). If it is, suspended losses from that activity are released.
8. Keep the hours records and the election statement with the return (see "Records an examiner asks for" below).

Why a rental loss is passive by default

Section 469 denies an individual, estate or trust a "passive activity loss" for the year (§ 469(a)). A passive activity is a trade or business in which the taxpayer does not materially participate. It also includes any rental activity, except as § 469(c)(7) provides (§ 469(c)(1) and (2)). So a rental is passive even if the owner works hard on it, unless the owner is a real estate professional and materially participates. Pub. 925 says the same: a rental activity is passive even if the owner materially participated, unless the owner materially participated as a real estate professional (Pub. 925).

What "passive" costs:

• The net passive loss cannot offset wages, business profit, interest or gains for that year. It can offset passive income from other activities.
• The disallowed loss is not lost. It is "treated as a deduction or credit allocable to such activity in the next taxable year" (§ 469(b)), and carries forward year after year.
• Suspended losses come free when the taxpayer disposes of the entire interest in the activity in a transaction in which all gain or loss is recognized. The loss from that activity, to the extent it exceeds net passive income from all other passive activities, is then treated as not passive. The release does not apply if the buyer is related under § 267(b) or § 707(b)(1) (§ 469(g)(1)).
• If an activity stops being passive (for example, the owner becomes a real estate professional), old suspended losses from it stay limited: they offset only income from that same activity, and any remainder is still treated as passive (§ 469(f)(1)).
• Form 8582 is where the computation is made, unless the taxpayer meets the instructions' exception for small rental losses with active participation (Instructions for Form 8582).

The active participation allowance and its phase-out

A natural person who actively participated in a rental real estate activity can deduct part of the passive loss from that activity against non-passive income (§ 469(i)(1)). Active participation is a lower bar than material participation. Pub. 925 gives approving new tenants, deciding on rental terms and approving expenditures as management decisions that can count (Pub. 925). The owner, together with a spouse, must hold at least 10 percent by value of all interests in the activity for the whole period, and an interest as a limited partner does not count (§ 469(i)(6)).

Rules for the allowance:

• It is a reduction, not a cliff. Each dollar of modified AGI above the phase-out start removes half a dollar of the allowance until it reaches zero (§ 469(i)(3)(A)).
• Modified AGI for this test is AGI computed without taxable social security, without deductions under §§ 219, 221 and 250, without certain exclusions, and without any passive activity loss or loss allowed by reason of § 469(c)(7) (§ 469(i)(3)(E)).
• A married person filing a separate return who did not live apart from the spouse at all times during the year gets no allowance at all (§ 469(i)(5)(B)). The reduced amounts in the table apply only to separate filers who lived apart all year.
• It applies only to rental real estate activities. An activity taken out of the rental definition by the short-term rental rule is not a rental activity, so the allowance is not the route for it (see the short-term rental section).

Worked example 1 (hypothetical). A married couple files jointly. Neither is a real estate professional. They actively participate in one long-term rental. Modified AGI is USD 130,000 and the rental loss is USD 18,000. The excess over the start is USD 130,000 minus USD 100,000, which is USD 30,000. Half of that is USD 15,000. The allowance is USD 25,000 minus USD 15,000, which is USD 10,000. They deduct USD 10,000 against other income and carry USD 8,000 forward as a suspended passive loss (§ 469(i)).

Worked example 2 (hypothetical). The same couple has modified AGI of USD 400,000. That is above the level where the allowance is fully gone, so the whole rental loss is suspended unless they have passive income (Pub. 925). This is the usual position of the high earner this Guide is written for, and the reason the two routes below matter.

Real estate professional status

If § 469(c)(7) applies for a year, the rule that every rental is passive does not apply to the taxpayer's rental real estate activities. Each interest in rental real estate is then a separate activity unless the taxpayer elects to treat them all as one (§ 469(c)(7)(A)). Status is not a deduction by itself. A rental real estate activity of a qualifying taxpayer "is a passive activity under section 469 for the taxable year unless the taxpayer materially participates in the activity" (Reg. § 1.469-9(e)(1)). So there are two gates, every year: qualify, then materially participate.

The two tests, both required, each tax year (§ 469(c)(7)(B)):

Test	Wording in the statute
Source	https://www.law.cornell.edu/uscode/text/26/469
Half test	"more than one-half of the personal services performed in trades or businesses by the taxpayer during such taxable year are performed in real property trades or businesses in which the taxpayer materially participates"
Hours test	"such taxpayer performs more than 750 hours of services during the taxable year in real property trades or businesses in which the taxpayer materially participates"

What counts, and who counts it:

• Real property trades or businesses are "any real property development, redevelopment, construction, reconstruction, acquisition, conversion, rental, operation, management, leasing, or brokerage trade or business" (§ 469(c)(7)(C)).
• Hours count toward the tests only from real property trades or businesses in which the taxpayer materially participates (Reg. § 1.469-9(c)(3)).
• Work as an employee counts in the total of personal services (the denominator of the half test). It does not count as real property work unless the employee is a 5-percent owner of the employer (§ 469(c)(7)(D)(ii); Reg. § 1.469-9(c)(5)). A full-time W-2 employee therefore almost never meets the half test, whatever hours they put into rentals.
• Investor-type work does not count as personal services: studying financial statements, preparing summaries for one's own use, and monitoring finances in a non-managerial capacity (Reg. § 1.469-9(b)(4); Reg. § 1.469-5T(f)(2)(ii)).
• On a joint return, the tests are met "if and only if either spouse separately satisfies such requirements" (§ 469(c)(7)(B)). The spouses' hours are not added together for the half test or the hours test. But in deciding which real property businesses a spouse materially participates in, the other spouse's work counts (Reg. § 1.469-9(c)(4)).
• Once one spouse qualifies, material participation in each rental is tested with both spouses' participation combined, whether or not they file jointly (Reg. § 1.469-5T(f)(3)).

Worked example 3 (hypothetical). Spouse A is a full-time employed engineer with about 2,000 hours at work. Spouse B has no other job and logs 900 hours a year finding, renovating, leasing and managing the couple's rentals through a property business in which B materially participates. B's real property hours are all of B's working hours, so B passes the half test, and 900 is more than 750, so B passes the hours test. The joint return qualifies through B alone. A's 2,000 employee hours do not stop B qualifying, and do not count toward B (§ 469(c)(7)(B)). The couple must still show material participation in each rental, or in the combined activity if they elect, counting both spouses' hours.

Worked example 4 (hypothetical). A self-employed consultant works 2,000 hours in the consulting business and 800 hours on rentals. Total personal services are 2,800 hours, so more than half would be more than 1,400 hours. 800 hours fails the half test even though it passes the hours test. No real estate professional status (§ 469(c)(7)(B)).

The election to treat all rentals as one activity

Without the election, each interest in rental real estate of a qualifying taxpayer is a separate activity, and material participation must be shown in each one (Reg. § 1.469-9(e)(1)). An owner with several properties rarely meets an hours test property by property. The election under Reg. § 1.469-9(g) treats all interests in rental real estate as a single activity, so the hours are added up across the portfolio.

• How to make it: file a statement with the original income tax return for the year. It must declare that the taxpayer is a qualifying taxpayer for the year and is making the election under section 469(c)(7)(A) (Reg. § 1.469-9(g)(3)).
• When: in any year the taxpayer qualifies. Not electing in one year does not stop an election in a later year (Reg. § 1.469-9(g)(1)).
• How long: binding for the year made and every later year in which the taxpayer qualifies, even after years in which they do not. It can be revoked only in the year of a material change in facts and circumstances, or a later year while those facts remain, with a statement on the original return. A year in which the election is less advantageous is not, by itself, a material change (Reg. § 1.469-9(g)(1) to (3)).
• Missed it: Rev. Proc. 2011-34 allows a late election by attaching the § 1.469-9(g)(3) statement to an amended return for the most recent tax year, marked "FILED PURSUANT TO REV. PROC. 2011-34", if all four hold: the only failure was not making the election on time; every affected return was filed consistently with the aggregation; each affected return was filed on time (within 6 months of its due date, excluding extensions); and there is reasonable cause. Relief does not decide whether the taxpayer qualifies or materially participates (Rev. Proc. 2011-34).

When the election hurts:

• Limited partnership interests. If the combined activity includes any interest held as a limited partner, the whole combined activity is treated as a limited partnership interest for material participation, and only the limited partner tests in Reg. § 1.469-5T(e)(2) can be used. This does not apply if gross rental income from all limited partnership interests is less than ten percent of gross rental income from all rental real estate interests for the year (Reg. § 1.469-9(f)).
• Selling one property. Suspended losses are released under § 469(g) only on a disposition of the entire interest in an activity (§ 469(g)). The Form 8582 instructions let a disposition of substantially all of an activity be treated as a separate activity if the prior-year unallowed losses and the year's result allocable to the part sold can be proved with reasonable certainty (Instructions for Form 8582). Once all rentals are one activity, work out before electing how a later sale of a single property will be treated.
• It cannot be undone because the client's plans change. It lasts until a material change in facts and circumstances.

Material participation: the seven tests

Material participation means involvement in the operations on a basis that is regular, continuous and substantial (§ 469(h)(1)). The regulation turns that into seven tests. An individual materially participates for the year "if and only if" one of them is met (Reg. § 1.469-5T(a)):

Source	https://www.ecfr.gov/current/title-26/chapter-I/subchapter-A/part-1/subject-group-ECFR3dff4ee5ffb0ae6/section-1.469-5T
(a)(1)	"participates in the activity for more than 500 hours during such year"
(a)(2)	participation "constitutes substantially all of the participation in such activity of all individuals (including individuals who are not owners of interests in the activity)"
(a)(3)	"participates in the activity for more than 100 hours during the taxable year, and such individual's participation in the activity for the taxable year is not less than the participation in the activity of any other individual (including individuals who are not owners of interests in the activity)"
(a)(4)	a significant participation activity (a trade or business activity with more than 100 hours of participation) where aggregate participation in all such activities "exceeds 500 hours"
(a)(5)	"materially participated in the activity ... for any five taxable years (whether or not consecutive) during the ten taxable years that immediately precede the taxable year"
(a)(6)	a personal service activity with material participation "for any three taxable years (whether or not consecutive) preceding the taxable year"
(a)(7)	"on a regular, continuous, and substantial basis during such year", based on all facts and circumstances

Limits that decide real cases:

• Test (a)(7) is not available to anyone who participates for 100 hours or less in the year (Reg. § 1.469-5T(b)(2)(iii)). Management time does not count toward (a)(7) if someone else is paid to manage the activity, or if another individual spends more hours on management (Reg. § 1.469-5T(b)(2)(ii)).
• Test (a)(4) works only for trade or business activities in the meaning of § 1.469-1T(e)(2) (Reg. § 1.469-5T(c)). A rental activity is not one of these (Instructions for Form 8582).
• Tests (a)(2) and (a)(3) compare the owner with every other individual, "including individuals who are not owners". A property manager, a cleaner or a contractor who puts in more hours than the owner defeats (a)(3).
• Work not customarily done by owners does not count if one of its principal purposes is to avoid the passive loss rules (Reg. § 1.469-5T(f)(2)(i)).
• Investor-type work does not count unless the individual is directly involved in day-to-day management or operations (Reg. § 1.469-5T(f)(2)(ii)).
• A spouse's participation counts as the taxpayer's, whether or not the spouse owns an interest and whether or not they file jointly (Reg. § 1.469-5T(f)(3)).
• A limited partner materially participates only under tests (a)(1), (a)(5) or (a)(6) (§ 469(h)(2); Reg. § 1.469-5T(e)(2)).

The short-term rental rule

The regulation takes some activities out of the "rental activity" definition. An activity involving the use of tangible property is not a rental activity for a year if, for that year (Reg. § 1.469-1T(e)(3)(ii)):

Exception	Wording in the regulation
Source	https://www.ecfr.gov/current/title-26/chapter-I/subchapter-A/part-1/subject-group-ECFR3dff4ee5ffb0ae6/section-1.469-1T
(A)	"The average period of customer use for such property is seven days or less"
(B)	"The average period of customer use for such property is 30 days or less, and significant personal services ... are provided by or on behalf of the owner of the property"
(C)	extraordinary personal services are provided, "without regard to the average period of customer use"

Exceptions (D) to (F) (incidental rentals, defined business hours, property provided to the owner's own partnership or S corporation) are in the same paragraph and are outside this Guide.

What follows from it. A short-term rental that meets exception (A) or (B) is not a rental activity, so § 469(c)(2) does not make it passive. The Form 8582 instructions then ask two questions: is it a trade or business activity, and did the owner materially participate? If the owner materially participated, the income or loss is reported "on the forms or schedules normally used" and stays off Form 8582 (Instructions for Form 8582). Real estate professional status is not needed for this route. Without material participation, the activity is passive, and the § 469(i) allowance does not help, because that allowance is written for rental real estate activities (§ 469(i)(1)).

How to compute the average period. For one class of property, divide the total days in all periods of customer use that end in the year (or include its last day) by the number of those periods. Each continuous or recurring right to use the property counts as one period, even across renewals. If the activity has more than one class of property with significantly different daily rents, weight each class's average by its share of gross rental income and add the results (Reg. § 1.469-1(e)(3)(iii)).

Significant personal services (exception B). Only services performed by individuals count. The test looks at all facts, including how often the services are given, the labour involved and their value compared with the rent. These do not count: services needed for lawful use of the property; construction and major repairs; and services similar to those commonly provided with long-term rentals of high-grade property, such as cleaning common areas, routine repairs, trash collection and security (Reg. § 1.469-1T(e)(3)(iv)).

Personal use and § 280A, at a high level:

• A dwelling is used as a residence if personal-use days exceed the greater of 14 days or 10 percent of the days rented at a fair rental (§ 280A(d)(1)). A day is a personal-use day if, for any part of it, the unit is used by the owner, by anyone else with an interest in it, by a family member (§ 267(c)(4)) of either, by anyone under an arrangement that lets the owner use another dwelling, or by any individual who does not pay a fair rental for that day (§ 280A(d)(2)). A day used for personal purposes is not a day rented at a fair rental for the 10 percent count (§ 280A(d)(1)).
• If that happens and § 280A(c)(5) applies, the income, deductions, gain and loss from that rental use are not taken into account for section 469 (§ 469(j)(10)). Instead § 280A(c)(5) caps the rental deductions at the gross rental income, after the deductions allowable anyway, and carries the excess forward (§ 280A(c)(5)). The rental cannot produce a loss against other income that year.
• If a dwelling used as a residence is rented for less than 15 days in the year, no rental deductions are allowed and the rent is not included in gross income (§ 280A(g)).

Worked example 5 (hypothetical). An employee with high wages buys a cabin. In 2026 it has 40 guest stays totalling 160 nights, all ending in the year. 160 divided by 40 is an average of 4 days, which is seven days or less, so the cabin is not a rental activity. The owner logs 120 hours on listing, guest messages, restocking and turnovers. The cleaning contractor logs 90 hours, and no other individual works more. The owner is above 100 hours and not below anyone else, so test (a)(3) is met (Reg. § 1.469-5T(a)(3)). A first-year loss of USD 70,000 (largely depreciation after a cost segregation study) is not passive. It can offset wages, subject to basis, at-risk and the excess business loss limit. The owner used the cabin for 10 personal days. 10 percent of 160 rental days is 16 days, so the greater figure is 16 days, and 10 days does not exceed it: the cabin is not used as a residence under § 280A(d)(1).

Worked example 6 (hypothetical, the trap). Same cabin, but the cleaning contractor logs 150 hours. The owner's 120 hours are now less than another individual's, so test (a)(3) fails. The owner is under 500 hours, so test (a)(1) fails. Test (a)(7) is open in principle (the owner is above 100 hours) but rests on facts and circumstances. The regulation sets no hours figure above 100 for test (a)(7). The owner's management hours do count here, because no one else is paid to manage and no one does more management hours (Reg. § 1.469-5T(b)(2)(ii)). Treat the loss as passive unless the facts-and-circumstances case is written up. On these facts the USD 70,000 loss is most likely passive and suspended (Reg. § 1.469-5T(a)).

Pairing with cost segregation and bonus depreciation

A cost segregation study splits a building's cost into shorter-lived components. Those components can qualify for bonus depreciation, so a purchase can create a large tax loss in its first year. That loss only reduces tax on other income if this Guide's tests are met for that year: real estate professional status plus material participation for a long-term rental, or material participation in a short-term rental that is not a rental activity. Otherwise the loss is suspended under § 469(b) and waits for passive income or a qualifying sale. For the study, the asset classes and the depreciation method, use us-federal-cost-segregation. For bonus depreciation and section 179 rules, use us-section-179-and-bonus-depreciation. For deferring gain on a sale by exchange, use us-section-1031-like-kind-exchange. This Guide does not repeat their methods.

The excess business loss limit

A loss that clears the passive rules can still be limited. The IRS instructions say that a non-corporate taxpayer's allowable business losses, after the at-risk and passive loss limits, "may be subject to the excess business loss limitation", figured on Form 461 (Instructions for Form 8582). The Form 461 instructions treat an activity as a trade or business if the "primary purpose for engaging in the activity is for income or profit and you're involved in the activity with continuity and regularity", decided on the facts (Instructions for Form 461). No IRS page says a real estate professional's rental or a short-term rental is one automatically. The disallowed excess is treated as a net operating loss carryover (§ 461(l)(2)). The limit applies in 2026. Section 70601 of Public Law 119-21 (the One Big Beautiful Bill Act) struck the end date "and before January 1, 2029" from § 461(l)(1) for taxable years beginning after 31 December 2026, so the limit no longer expires (Public Law 119-21). For 2026 the threshold is:

Same, joint returns	USD 512,000	same sentence

Records an examiner asks for

The regulation lets participation be shown "by any reasonable means". Contemporaneous daily logs are not required if participation can be shown otherwise, for example by "appointment books, calendars, or narrative summaries" identifying the services and approximate hours (Reg. § 1.469-5T(f)(4)). In practice, prepare for these requests:

• A dated log of hours per property (or per combined activity), per spouse, with the task done. Build it during the year from calendars, emails, booking platform messages and invoices.
• For real estate professional status: total hours in all trades or businesses, including employment, so the half test can be checked. Payroll or timesheet records from any job.
• Hours of everyone else who worked on the property (property managers, cleaners, contractors), because tests (a)(2) and (a)(3) compare against them.
• For short-term rentals: the booking history (each stay's dates) to prove the average period of customer use, and a record of personal-use days.
• The § 1.469-9(g) election statement filed with the original return, and the year it was first made.
• Ownership and entity documents showing any limited partnership interests and the percentage owned (the active participation test needs at least 10 percent by value).
• Form 8582 carryforward workpapers by activity, so suspended losses can be released on a full disposition.

Ask the client first

• How many hours did each spouse work in 2026 in every job and business, including employment, and how many in real estate work? Who can show it?
• For each property: what was the average length of a guest stay, how many personal-use days were there, and who else (manager, cleaner, contractor) worked on it and for how many hours?
• Is any rental held through a limited partnership, an LLC taxed as a partnership, or an S corporation, and what percentage does the client own?
• Has the client ever filed a § 1.469-9(g) election to treat all rentals as one activity, and in which year?
• What is the expected modified AGI, and are there suspended passive losses carried in from earlier years, by property?
• Is a sale, exchange or transfer to a family member planned?

When to refuse or refer

• Refuse to sign a position that the client is a real estate professional when the client works full time as an employee and is not a 5-percent owner of the employer. Employee hours count in the total but not as real property hours, so the half test is met only if documented real property hours in businesses with material participation exceed all employee hours in the year (§ 469(c)(7)(B); Reg. § 1.469-9(c)(5)). Refuse unless the log shows that.
• Refuse to build hours after the year from memory alone, or to count hours of work whose purpose is to avoid the passive rules (Reg. § 1.469-5T(f)(2)(i)).
• Refer when a late § 1.469-9(g) election outside Rev. Proc. 2011-34, a revocation, or a grouping question under Reg. § 1.469-4 is in play; when interests are held through tiered partnerships or S corporations; when the property is used under the other rental exceptions (C) to (F); or when a related-party sale or a 1031 exchange is planned (see us-section-1031-like-kind-exchange).
• Refer state treatment. States may not follow federal bonus depreciation or the passive rules in the same way; this Guide is federal only.
