The passive activity loss rule
Under Section 469, losses from "passive activities" (rental real estate, unless an exception applies) can only offset income from other passive activities — not wages, not business income from active participation, not investment income. Unused passive losses are suspended and carried forward until you either have passive income or dispose of the activity in a taxable transaction.
For a high-income investor with significant depreciation, this can mean years of suspended losses piling up on the balance sheet while you pay tax on your active income. REPS is the door out of that trap.
What real estate professional status does
If you qualify as a real estate professional, your rental real estate activities are not automatically passive. Combined with material participation, your rental losses become non-passive and can offset any income — wages, business, capital gains. For an investor with $100K+ of annual depreciation from cost segregation, REPS can convert a large paper loss into a large real deduction.
The two-part test for REPS
To qualify, you must meet both prongs in the same tax year:
- 750-hour test. More than half of the personal service hours you perform in all trades or businesses during the year must be in real property trades or businesses.
- Material participation. You must materially participate in each rental activity (or in a grouped rental activity) — generally 500+ hours, or the activity being one of your principal activities under the seven material participation tests.
The 750-hour test is the harder one for investors who also have a full-time W-2 job. If you work 2,000 hours at a job and 750 hours in real estate, you fail — 750 is not more than half of 2,750. REPS is designed for investors whose real estate is their primary occupation.
Material participation: the seven tests
You materially participate in an activity if you meet any one of the IRS tests:
- You participate for more than 500 hours during the year.
- Your participation is substantially all the participation in the activity by all individuals.
- You participate for more than 100 hours and no one else participates more.
- The activity is a "significant participation activity" and your total significant participation hours across all such activities exceed 500.
- You materially participated in the activity for any five of the prior ten years.
- The activity is a personal service activity and you materially participated for any three prior years.
- Based on all the facts and circumstances, you participate on a regular, continuous, and substantial basis.
The $25,000 special allowance (for non-REPS)
If you do not qualify as a real estate professional, you may still deduct up to $25,000 of rental losses against non-passive income under Section 469(i) — the "active participation" allowance. This phases out between $100,000 and $150,000 of modified adjusted gross income (MAGI). Many investors with moderate income and one or two rentals use this. High earners are fully phased out and need REPS to deduct losses.
The grouping election
Meeting the 500-hour material participation test on a single rental property is hard if you own several. The grouping election under Section 469(f) lets you treat multiple rental activities as a single activity for material participation purposes — so your hours across all properties count together. Grouped correctly, 100 hours each on five properties becomes 500 hours on one grouped activity.
The grouping election is made on the return and is binding in future years unless there is a material change. The properties must form an "appropriate economic unit." A common and defensible grouping is all residential rentals owned by the same investor; mixing residential and commercial, or rentals and a development project, requires more analysis.
California conformity
California generally conforms to the federal passive activity loss rules, including the REPS determination and the $25,000 allowance. The same hours, the same tests, and the same grouping election apply on the California return. The documentation that defends your federal REPS position defends your California position.
The short-term rental exception
There is a narrow exception: if the average rental period is seven days or less (short-term rentals, Airbnb-style), the activity is not treated as a rental activity at all — it is a trade or business, and the passive rules apply based on material participation, not the rental presumption. This can let an active short-term rental operator deduct losses without REPS. The average-stay threshold is strict, and providing "substantial services" (concierge, daily cleaning, meals) pushes the activity into a different category. We evaluate whether your short-term rental qualifies.
Documentation: the part that fails audits
The IRS does not accept estimates or after-the-fact reconstructions of time. To defend REPS, you need contemporaneous time logs — a record kept at or near the time the work is done, showing the date, the activity, the hours, and the nature of the work. A log reconstructed in April when the audit notice arrives will not hold. We help clients set up a simple time-tracking system (a spreadsheet, an app, a calendar) that documents the 750 hours and the material participation hours in a form the IRS accepts.
How we help
- REPS qualification analysis before the tax year starts — so you know what hours you need
- Grouping election design and filing
- Time-log setup and documentation standards
- Short-term rental exception evaluation
- Passive loss tracking and release when the activity is disposed of
- Audit defense with the contemporaneous records to back the position
REPS is one of the highest-value positions in real estate tax — and one of the most commonly blown by investors who claim it without the hours or the records. If you are a Los Angeles investor with significant rental losses and real hours in your properties, this is worth a conversation before the year is over.
