They are two different doors out of the passive-loss rules, and most short-term rental owners only need one of them. Real estate professional status (REPS) under IRC §469(c)(7) is for owners of long-term rentals: it takes 750 hours plus a more-than-half test, per person, with no combining of spouses. The short-term rental exception under Treas. Reg. §1.469-1T(e)(3) works differently: if the average guest stay is seven days or less, the activity is not a "rental activity" at all, and the only remaining question is material participation. An owner with a qualifying STR does not need REPS, and the hours spent on that STR generally should not be assumed to count toward the 750.
Two doors, one wall
IRC §469 treats losses from passive activities as usable only against passive income. Two rules push rental losses onto the passive side by default: a trade or business is passive unless you materially participate, and a rental activity is passive regardless of participation, with limited exceptions.
REPS attacks the second rule. If you qualify, your rental real estate activities are no longer automatically passive, and each one is then tested for material participation like any other business. The STR exception avoids the second rule entirely. An activity with an average customer use of seven days or less is excluded from the definition of "rental activity," so it was never automatically passive to begin with. It goes straight to the material participation tests in Treas. Reg. §1.469-5T. The STR loophole guide walks through those tests.
What REPS requires
To be a real estate professional for a year, IRC §469(c)(7)(B) generally requires that:
- more than half of the personal services you perform in all trades or businesses during the year are in real property trades or businesses in which you materially participate, and
- you perform more than 750 hours of services in those real property trades or businesses.
Both prongs are measured per person. On a joint return, one spouse must meet both on their own; the statute does not let a couple add their hours together to reach 750. The Tax Court applied exactly that rule in Hairston (T.C. Memo 2019-104), where the couple conceded they could not combine hours and the case turned on whether the husband alone had 750.
Qualifying as a real estate professional is only the first step. You must still materially participate in each rental activity, or make the election under Treas. Reg. §1.469-9(g) to treat all rental real estate interests as one activity. See the 750-hour test guide for the mechanics of the two prongs.
For a full-time W-2 employee, the more-than-half prong is usually the wall. A 2,000-hour job means more than 2,000 hours of real estate work before REPS is even arguable, and hours as an employee count toward real property trades only if you own more than 5 percent of the employer.
What the STR exception requires
The STR route has no 750-hour floor and no more-than-half test. It has three questions, all answered under the regulations rather than the statute:
- Is the average period of customer use seven days or less for the year (Treas. Reg. §1.469-1T(e)(3)(ii)(A))?
- Did you materially participate in the activity under one of the seven tests in Treas. Reg. §1.469-5T(a)? For most hosts the realistic ones are 500 hours, 100 hours and more than any other individual, or substantially all of the participation.
- Do personal-use days, basis, at-risk, or other limits cut in?
Spouses are treated differently here too. For material participation in an activity, IRC §469(h)(5) attributes a spouse's participation to the taxpayer, so a couple's combined work on the STR generally counts toward the 100 or 500 hours. That is the opposite of the REPS rule and a common point of confusion.
The trap: STR hours and the 750
Owners who hold both a short-term rental and long-term rentals sometimes plan to use the STR hours to reach 750 and unlock losses on the long-term properties.
The 750 hours must be in "real property trades or businesses," a term IRC §469(c)(7)(C) defines by a list of activities that includes rental, operation and management of real property. Whether time spent on an activity that the regulations say is not a rental activity fits inside that definition is a question practitioners answer differently, and the reporting position is not one this post can settle. Many CPAs take the conservative view and do not count STR hours toward the 750 when planning. If your REPS position depends on those hours, that is a conversation to have before the year is over, not after.
The safer framing is the one the regulations invite: the STR qualifies on its own through material participation, and REPS is evaluated separately on the long-term rental hours alone.
Owners with both kinds of property
Suppose you own a lakeside cabin with three-night average stays and two long-term rental houses. The cabin is analyzed under the STR exception: seven-day average, then material participation in the cabin activity. The houses are rental activities and stay passive unless one of you is a real estate professional who also materially participates in them.
That produces two independent tests with two independent hour totals:
| Question | STR (cabin) | Long-term rentals |
|---|---|---|
| Is it a rental activity? | No, if average stay ≤ 7 days | Yes |
| Door out of passive treatment | Material participation | REPS + material participation |
| Hours target | 100 (and more than anyone else) or 500 | 750 plus more-than-half, per person |
| Spouse's hours | Generally attributed | Not combined for 750 |
| Grouped with the other? | Generally not, since it is not rental real estate | Rental interests may be aggregated by election |
Which log to keep for each
The record-keeping consequence is that one running total is not enough. Each entry needs a property, a person, and a duration, and the totals need to roll up two ways: per STR activity for material participation, and per person across long-term rental work for REPS.
For an STR, the entries that matter are operational: turnovers, guest communication, repairs, pricing, vendor coordination. The other-participants comparison also has to be documented, because the 100-hour test asks whether anyone else did more.
For REPS, the log has to support both prongs. That means logging real estate hours per person, not per household, and being ready to show what the rest of your working time looked like so the more-than-half comparison can be made. Hairston is a useful warning: 932 recorded hours across a couple, uniform one-hour entries for trivial tasks, and the court found the husband's share inflated by at least 150 hours, below 750.
STR Tracker lets you set a goal per property, STR or REPS, so each property's entries count toward the test that actually applies to it and the export shows the two totals separately. Tag the property and the person on every entry from January; reconstructing that split in March is where these logs fall apart.
Decision table
| Your situation | Likely door | Log to keep |
|---|---|---|
| Only short-term rentals, average stay 7 days or less | STR exception; REPS not needed | Per-property STR hours plus other participants' hours |
| Only long-term rentals, one spouse without a full-time job | REPS, if 750 and more-than-half are realistic | Per-person real estate hours, all trades or businesses |
| Long-term rentals, both spouses full-time W-2 | REPS usually out of reach; losses likely passive | Log anyway; ask about the §469(i) allowance and carryforwards |
| Both STR and long-term rentals | STR on its own; REPS evaluated on long-term hours alone | Two totals, per property and per person |
| STR with average stay drifting over 7 days | Neither, unless REPS applies | Watch the average monthly |
REPS has more moving parts than this post covers: personal services, the aggregation election and its timing, and how prior-year elections bind. The STR route has fewer parts but a harder comparison test when you use cleaners or a manager. In either case the log is the evidence, and the test is chosen before the hours are logged, not after.
