Treasury Reg §1.469-1T(e)(3)(ii)(A): the 7-day rule that makes short-term rentals non-passive
When the average period of customer use for a rental property is 7 days or fewer in a tax year, 26 CFR §1.469-1T(e)(3)(ii)(A) takes that activity out of the “rental activity” definition under IRC §469. Combined with material participation under §1.469-5T, losses from the activity offset W-2 and business income directly — without Real Estate Professional Status.
This page reproduces the regulation text, walks through how the 7-day average is calculated, places exception (A) alongside the other five §1.469-1T(e)(3)(ii) carve-outs, and shows the worked numbers a CPA needs to support the position. A $500K STR with a 4.8-day average and 112 documented owner hours produces roughly $56,000 of Year-1 federal tax savings when paired with a cost segregation study under Rev. Proc. 87-56 and 100% bonus depreciation under §168(k) (permanent post-OBBBA).

“An activity involving the use of tangible property is not a rental activity for a taxable year if for such taxable year — (A) the average period of customer use for such property is seven days or less …”
Source: 26 CFR §1.469-1T(e)(3)(ii)(A) (Cornell Legal Information Institute). The full regulation lists six carve-outs (A)–(F); the above text reproduces only (A).
| Plain-English summary | A rental property whose paying-guest stays average a week or less for the year is treated as a non-rental activity under §469. The default passive-loss limitation does not apply. |
| Governing statute | 26 U.S.C. §469 (passive activity losses limited); regulation issued by Treasury under §469(l) rulemaking authority |
| Regulation type | Temporary regulation (denoted by the “T” suffix). In force since 1988; treated as authoritative by Tax Court despite the temporary designation. |
| Test threshold | Annual average; calculated as total customer-use days ÷ number of rental periods. Tested separately each tax year. |
| Material participation interaction | Meeting (A) is necessary but not sufficient to claim losses against W-2 income. The owner must also materially participate under one of the seven tests in §1.469-5T. |
| Common name | “The short-term rental loophole,” “the 7-day rule,” “the STR exception” |
| Recordkeeping standard | Booking-by-booking log showing check-in / check-out dates, guest count, and rental period. Owner-hours log for the material participation test. Hairston v. Comm'r denied the position where the taxpayer could not substantiate either. |
| Companion regulation | 26 CFR §1.469-5T sets the seven material participation tests. Test 3 (more than 100 hours and more than any other individual) is the most common qualifying test for STR owners. |
What this regulation does.
IRC §469, enacted in 1986, splits the world into “passive” and “non-passive” income. Losses from passive activities can only offset passive income; they cannot reduce W-2 wages, business income, or portfolio income. Rental activity is passive per se under §469(c)(2), with no participation test — even a real estate professional who works 80 hours a week on a rental cannot use those losses against W-2 income unless they qualify under §469(c)(7).
Treasury Reg §1.469-1T(e)(3)(ii) carves six specific activities out of the “rental activity” definition entirely. Exception (A) is by far the most-used in practice: when the property's average customer stay is 7 days or fewer, the activity stops being a rental for §469 purposes. The same property, with the same revenue stream, becomes a regular trade-or-business activity if the owner materially participates. Losses from a trade or business under §162 offset W-2 income at marginal rates with no Real Estate Professional Status hurdle.
The economic effect of (A) is large because cost segregation studies under Rev. Proc. 87-56 typically reclassify 20–35% of an STR's depreciable basis into 5-, 7-, and 15-year MACRS classes that qualify for 100% bonus depreciation under §168(k). On a $500K STR, that produces roughly $30,000–$60,000 of Year-1 federal tax savings against W-2 income for an owner in the 32–37% brackets — provided exception (A) applies and material participation under §1.469-5T is documented.
The regulation does not create a deduction. It changes the character of losses produced by a property that already qualifies for accelerated depreciation. The size of the loss is set by the cost segregation study; the usability of that loss is set by (A) plus material participation.

How to calculate average period of customer use.
The regulation specifies the arithmetic in §1.469-1T(e)(3)(iii): “the average period of customer use for property shall be determined by dividing — (A) the aggregate number of days of customer use for the taxable year by (B) the number of periods of customer use during the taxable year.” Vacancies and owner personal-use days are excluded.
- 01Sum total customer-use days for the tax year
Add up every day a paying customer occupied the property. Vacancies do not count. Owner personal-use days do not count toward customer use (they may trigger §280A limits separately).
- 02Count the number of separate rental periods
Each booking is one rental period. A 5-night Airbnb stay is one rental period. Two back-to-back guests counted separately produce two rental periods.
- 03Divide total days by total rental periods
The quotient is the average period of customer use. If 180 customer-use days were split across 35 bookings, the average is 5.14 days.
- 04Compare against the 7-day threshold under (A)
If the average is 7.0 days or less for the tax year, the property meets exception (A) and is not a rental activity for §469 purposes for that year.
- 05If (A) fails, test (B) at the 30-day threshold with services
When the average exceeds 7 days, you may still escape passive treatment under (B) if (i) the average is 30 days or less and (ii) significant personal services are provided alongside the rental.
The six exceptions under §1.469-1T(e)(3)(ii).
Exception (A) is the most common path, but five other carve-outs exist in the same paragraph. Any one of them takes the activity out of the “rental activity” classification.
Material participation under §1.469-5T.
Exception (A) takes the activity out of the passive bucket. Material participation under 26 CFR §1.469-5T(a) is the second hurdle. A taxpayer materially participates in an activity for a tax year by satisfying any one of seven tests:
Test 3 carries most STR positions because the threshold is reachable (100 hours over a year is about 2 hours per week) and most owner-operated STRs do not have any other individual logging more hours. The defeating combination is a full-service property manager whose hours exceed the owner's, which is why the owner's contemporaneous hour log is the single most important audit document for the position. Hairston v. Comm'r, T.C. Memo. 2019-104, denied losses where the taxpayer could not produce contemporaneous records.
Worked example: $500K STR meeting exception (A).
The numbers below describe a typical desert / mountain STR placed in service in early 2025, with the 7-day average satisfied and one owner logging participation hours alongside a cleaner and a property manager.
The result is a roughly $152,000 first-year deduction available against W-2 wages, producing about $56,000 of federal tax savings at the 37% marginal rate. The same property without exception (A) produces an identical $152,000 deduction on the depreciation schedule, but the loss is suspended under §469 until the owner has passive income or disposes of the property in a fully taxable transaction.

Why investors call this the “STR loophole.”
The colloquial term “short-term rental loophole” refers to the combination of three statutory and regulatory moves: exception (A) under §1.469-1T(e)(3)(ii), material participation under §1.469-5T, and 100% bonus depreciation under §168(k). None of these moves is novel or aggressive. Each was enacted by Congress or promulgated by Treasury under standard rulemaking authority. The combination produces the unusual result that a real estate investment can throw off W-2-offsetting losses without Real Estate Professional Status.
What gives the construction its “loophole” reputation is that the regulation predates the Airbnb-driven STR market by about three decades. §1.469-1T was promulgated in 1988 to address hotels and bed-and-breakfasts, not vacation rentals. The 7-day threshold was selected because that is roughly the dividing line between hotel-like and apartment-like use patterns under pre-1986 case law. STR platforms simply made it possible for ordinary property owners to operate at hotel-like average durations — and the regulation does not care how the booking platform classifies the listing, only what the actual average customer stay turns out to be.
The strategy is widely used and well documented in Tax Court decisions. The IRS audits the position regularly; what wins or loses the case is the contemporaneous record of bookings and owner participation hours. Our buyer-applied summary of the strategy: how STR cost segregation works →.
Form 3115 lookback for prior years that met (A).
Exception (A) is tested year-by-year. An owner whose 2022, 2023, and 2024 booking patterns satisfied the 7-day average but who never claimed accelerated depreciation can recover the missed deductions in a single current-year adjustment under §481(a). The mechanism is a Form 3115 change in accounting method under Rev. Proc. 2015-13 (automatic consent — no IRS pre-approval required).
The §481(a) catch-up amount equals the cumulative depreciation that would have been claimed using accelerated MACRS classes minus the depreciation actually claimed using the default 27.5-year schedule. No amended returns are filed. The full adjustment is reported in the current year and, for owners whose current-year activity also meets (A) with material participation, the adjustment offsets W-2 income at the marginal rate. For owners whose current-year activity does not meet (A), the adjustment is suspended as a passive loss.
Five mistakes that cost taxpayers the position on audit.
- Reading (A) as a 7-day maximum. The threshold is an average, not a cap. A property with one 30-day booking and twelve 4-day bookings averages 6 days (78 customer-days ÷ 13 periods) and meets (A). A property where every booking is a 7-day stay also meets (A). A property where every booking is an 8-day stay does not, even though no single stay would be unusual.
- Including owner personal-use days in the average. The numerator counts only paying-customer days; the denominator counts only paying-customer rental periods. Owner family use is not in either. Including owner-use days inflates the numerator and skews the average upward (or, if rental periods are also miscounted, can skew either direction). The §280A vacation-home rules govern personal-use day treatment separately.
- Failing to log owner participation hours contemporaneously. The material participation test under §1.469-5T does not require a specific recordkeeping format, but reconstructed-after-the-fact logs lose at audit. Hairston v. Comm'r explicitly cited the absence of contemporaneous records. A simple weekly note — date, hours, task — carries the position.
- Forgetting that property manager hours count against test 3. Test 3 requires the owner's hours to exceed those of every other individual, not just “more than the cleaner.” A full-service property manager spending 150 hours a year on the listing defeats an owner logging 110 hours. Owners using full PMs typically need to qualify under test 1 (500+ hours) or test 2 (substantially all participation), which is much harder.
- Treating booking-platform classification as the test. An Airbnb listing whose actual bookings averaged 12 days because guests stayed multi-week does not meet (A) regardless of how Airbnb categorizes the listing. Conversely, a VRBO listing whose bookings averaged 5 days meets (A) regardless of how VRBO categorizes it. The test is the booking record, not the platform's label.

Frequently asked questions about §1.469-1T(e)(3)(ii)(A).
Is 26 CFR §1.469-1T the same as Treasury Regulation §1.469-1T?
Yes. 26 CFR §1.469-1T is the Code of Federal Regulations citation; Treasury Reg §1.469-1T is the same temporary regulation, issued by the U.S. Treasury Department under the authority of IRC §469. Both citations point to the same text. The 'T' denotes a temporary regulation; despite that label, §1.469-1T has been in force since 1988 and tax courts treat it as authoritative.
What does 'average period of customer use 7 days or less' mean?
It refers to the calendar-day average length of paying customer stays during the tax year. Calculate it as total customer-use days divided by the number of separate rental periods. If 60 paying-guest bookings produced 270 occupied days in the year, the average is 4.5 days. Owner personal-use days and vacancies are excluded from both the numerator and the denominator. The threshold is checked annually.
Does §1.469-1T(e)(3)(ii)(A) apply to every Airbnb?
Not automatically. The rule requires the actual booking pattern to produce an average stay of 7.0 days or less for the tax year. A property listed on Airbnb but rented mostly to monthly guests would fail (A) and need to test against (B). The exception applies to the activity in a given year, not to the platform or the listing format.
Do I still need Real Estate Professional Status (REPS) under §469(c)(7) to use losses from a short-term rental?
No. The whole point of the §1.469-1T(e)(3) exceptions is to take the activity out of the passive-activity category in the first place. An activity that meets (A) is not a 'rental activity' under §469, so the REPS hours requirement under §469(c)(7) does not apply. You still need to materially participate under §469(h) to claim losses against non-passive income.
What if my average rental period is 7.5 days for the year?
Exception (A) fails because 7.5 exceeds the 7.0 ceiling. The activity is then tested against (B): if the average is 30 days or less and you provide significant personal services (cleaning between every stay alone is generally not sufficient; daily housekeeping, concierge, or meals can qualify), the activity still escapes passive treatment. If neither (A) nor (B) applies, the activity is passive under the default §469 rule.
Does §1.469-1T(e)(3)(ii)(A) require material participation by itself?
No. Meeting (A) takes the activity out of the 'rental' bucket, but losses are only deductible against non-passive income (W-2 wages, business income) if you also materially participate under §469(h). The seven material participation tests are listed in Treas. Reg. §1.469-5T. The most common qualifying test for STR owners is test 3: more than 100 hours of participation, and more participation than any other individual.
Who counts toward 'no other individual participates more' under the material participation test?
Any individual whose work in the activity is counted: spouses, cleaners, co-hosts, on-site property managers, handymen, and (in many readings) full-service property management companies. The test is satisfied only if the owner's hours exceed every other individual's hours. A cleaner working 120 hours/year defeats this test for an owner logging 110 hours.
How does §1.469-1T(e)(3)(ii)(A) interact with cost segregation?
Cost segregation reclassifies a portion of the property's basis from 27.5-year MACRS into 5-, 7-, and 15-year classes per Rev. Proc. 87-56, allowing 100% bonus depreciation under §168(k) on the reclassified portion. The depreciation amount is the same whether the activity is passive or not. What (A) changes is whether the resulting losses can offset W-2 or business income. Without (A), the losses are suspended under §469 until you have passive income or dispose of the property.
Can I retroactively use §1.469-1T(e)(3)(ii)(A) on a property I already own?
Yes, on a year-by-year basis. The 7-day average test is applied each tax year independently. If your 2024 booking pattern met (A) and you did not take a cost segregation study or claim accelerated depreciation, you can file Form 3115 (Application for Change in Accounting Method) with a current-year return to claim missed depreciation under §481(a). Automatic-consent change under Rev. Proc. 2015-13.
Does the 7-day rule under (A) include owner personal-use days?
No. Only days the property is occupied by paying customers count toward both the numerator (total customer-use days) and the denominator (number of rental periods). Owner and family personal-use days are excluded from the calculation, though those days may trigger separate §280A limits on deductions in years with significant personal use.
Are vacancy days included in the average period of customer use?
No. Vacant days between bookings are excluded from both the numerator and the denominator. The calculation looks only at days the property was occupied by a paying customer, divided by the number of separate rental engagements.
What court cases have applied §1.469-1T(e)(3)(ii)(A)?
Hairston v. Comm'r, T.C. Memo. 2019-104, and Eger v. United States, 393 F. Supp. 2d 1110 (N.D. Cal. 2005), are the most-cited applications. Hairston denied losses where the owner could not substantiate the average rental period; Eger illustrated the strict reading of the material participation test alongside the (A) exception. Both cases highlight that record-keeping for booking durations and owner hours is what wins or loses the position on audit.
