Real estate professional status, in plain words

A cost segregation study can produce a very large first-year deduction. Whether that deduction does anything for you this year is a separate question, and it is not answered by the study. It is answered by IRC §469, which sorts income and losses into passive and non-passive buckets and will not let a passive loss offset your wages.

Rental losses are passive by default, no matter how much work you put in. Real estate professional status is the main exception. Qualify, and your rental losses become non-passive and can offset ordinary income, including a W-2 salary. Fail, and the loss suspends and waits.

The two tests, both required

Section 469(c)(7)(B) sets two hurdles for a tax year, in the statute's own words. You have to clear both.

1. More than one-half of the personal services you performed in trades or businesses during the year were performed in real property trades or businesses in which you materially participate.
2. More than 750 hours of services during the year in real property trades or businesses in which you materially participate.

Read the italics twice, because they are the part almost every summary drops. Material participation is not a later step: hours only count toward these two tests if you materially participate in the business that generated them. Treas. Reg. §1.469-9(c)(3) says it directly, that a taxpayer must materially participate in a real property trade or business in order for services in it to count.

The first test is the one people miss, and it is worth being blunt about. If you work 2,000 hours at a job that is not real estate, you would need more than 2,000 qualifying hours to clear it. That is why a physician, engineer or software developer with a demanding day job generally cannot qualify on their own hours, however many rentals they own.

The employee trap

Under §469(c)(7)(D)(ii) and Treas. Reg. §1.469-9(c)(5), personal services you perform as an employee do not count as performed in a real property trade or business unless you are a five-percent owner of that employer. Work for a property-management company you do not own a five-percent stake in, and those hours do not help you here, even though the work itself is squarely real-property work. If you become a five-percent owner partway through the year, only the services performed while you held that stake count.

What counts as a real property trade or business

Section 469(c)(7)(C) lists them: development, redevelopment, construction, reconstruction, acquisition, conversion, rental, operation, management, leasing, and brokerage. Note what is on that list: management and operation count, so hands-on landlording is qualifying work. Note also what is not: your own investing research, and time spent as an investor rather than an operator, does not count.

The married-couple rule, which cuts both ways

These two rules sit next to each other and point in opposite directions, which is why they get muddled.

For the 750-hour and one-half tests, spouses cannot pool hours. A joint return qualifies "if and only if either spouse separately satisfies" both requirements (§469(c)(7)(B), and Treas. Reg. §1.469-9(c)(4)). One person has to get there alone.

For material participation, the opposite applies. Under Treas. Reg. §1.469-5T(f)(3), a spouse's participation counts as the taxpayer's, whether or not the spouse owns any interest in the activity and whether or not they file jointly.

The practical consequence is sharper than "it helps". The classic setup of a high-earning spouse plus a non-working spouse works only if the non-working spouse individually logs more than 750 hours and clears the one-half test on their own time. You cannot add the earner's weekend hours to get there. Once one spouse does qualify, a joint return puts the freed-up losses against the household's income, and for the separate material-participation test the couple's hours do combine.

Then material participation again, at the property level

Clearing the two tests makes you a qualifying taxpayer, which switches off the rule that makes rental activity automatically passive. It does not make your rental losses non-passive. Treas. Reg. §1.469-9(e)(1) is explicit: a qualifying taxpayer's rental real estate activity is still a passive activityunless the taxpayer materially participates in that activity. The Ninth Circuit affirmed the point in Gragg v. United States, 831 F.3d 1189 (9th Cir. 2016).

So material participation is tested twice, at two different levels: once on the businesses whose hours you are counting toward the 750, and again on the rental activity whose loss you want to use. Treas. Reg. §1.469-5T(a) supplies the seven tests, and meeting any one of them is enough.

1. You participate more than 500 hours in the activity.
2. Your participation is substantially all the participation in the activity by anyone.
3. You participate more than 100 hours and no other single individual participates more. "Any other individual" includes people who own nothing: your cleaner, handyman, landscaper and especially your property manager. This is the test most owners actually use, and the one a full-service manager quietly destroys.
4. The activity is a significant participation activity (over 100 hours) and your total across all such activities exceeds 500 hours. In practice this one rarely helps a landlord, because a significant participation activity has to be a trade or business activity.
5. You materially participated in 5 of the last 10 years.
6. The activity is a personal service activity in which you materially participated for any 3 prior years.
7. Based on all facts and circumstances, you participate on a regular, continuous and substantial basis. Treat this as a last resort: it is unavailable below 100 hours, and management time does not count toward it if anyone else is paid to manage the activity.

Tests 1 and 3 are the ones owners use in practice. Test 3 is easier than it looks and is where a property manager becomes a problem: if the manager puts in more hours than you do, you fail it.

The grouping election

Material participation is tested activity by activity, and §469(c)(7)(A)(ii) treats each interest in rental real estate as a separate activity by default. Own five rentals and you would have to clear a test on each one. An election under Treas. Reg. §1.469-9(g) lets you treat all your rental real estate as a single activity, so participation across the portfolio is aggregated into one test.

Three things the regulation is specific about, and they matter before you make it:

• It is made by filing a statement with your original returndeclaring that you are a qualifying taxpayer and making the election under §469(c)(7)(A).
• It is binding for that year and all future years in which you are a qualifying taxpayer, even if there are intervening years when you are not.
• It can be revoked only on a material change in your facts and circumstances. The regulation says outright that the election simply turning out to be less advantageous is not, by itself, a material change.

There is also a structural consequence: because the properties become one activity for all purposes of §469, that includes the disposition rules, so selling a single property is no longer a disposition of the whole activity that frees its suspended losses.

And one trap worth stating plainly, because it catches exactly the readers this site attracts: a short-term rental cannot be included in a §1.469-9(g) election. The election covers interests in rental real estate, and an activity that escapes the per-se rule under the seven-day test is not a rental activity. If your portfolio mixes short-term and long-term rentals, the grouping question gets more complicated, not less. Whether to elect is a planning decision for your CPA, not a box to tick because it makes this year easier.

Hours: what the Tax Court actually accepts

Most REPS and material-participation claims fail on the records, not the law. Treas. Reg. §1.469-5T(f)(4) does say participation may be established "by any reasonable means" and that contemporaneous daily logs "are not required". Read that as a description of the rule and not as advice, because in practice courts rarely credit a reconstruction.

Four cases show exactly what loses:

• Mirch (T.C. Memo. 2025-128). Undated logs with standardized blocks: 12 minutes per email, 7 hours per cleaning regardless of how long the stay was, and 8 hours of "on call" time for every rental day, totalling 744.5 hours. The court called it a "ballpark guesstimate" and held that on-call time is not work. Stripped of it, they could not reach even 100 hours. The property did qualify as a short-term rental under the seven-day rule. They still lost, on participation.
• Hakkak (T.C. Memo. 2020-46). Handwritten calendars that lacked specificity, and the fatal gap: he never produced hours for his law practice, so he could not show more than half his time was in real estate even in principle. If you are claiming the one-half test, you have to document the other side of the fraction too.
• Sezonov (T.C. Memo. 2022-40). A full-time HVAC business owner with two Florida rentals. Neither spouse could show more than 750 hours. A full-time non-real-estate business is close to fatal to the one-half test.
• Pourmirzaie (T.C. Memo. 2018-26). A log reconstructed from memory after the audit began, showing her at the properties every Saturday, contradicted by her own bank and credit card statements placing her elsewhere.

The working standard those cases imply: contemporaneous, dated, per property, per task, with specific descriptions. Round numbers and uniform blocks lose. Investor-type work does not count at all under Treas. Reg. §1.469-5T(f)(2)(ii), which names reviewing financial statements, preparing summaries for your own use, and monitoring operations in a non-managerial capacity. We publish a free hours log built for this.

If you cannot qualify, you are not out of options

Most people who want a cost segregation loss to offset a salary cannot meet the half-your-time test, and it is worth saying plainly that this is normal. Three routes remain.

• The short-term rental route. A rental whose average period of customer use is seven days or less is not a rental activity under Treas. Reg. §1.469-1T(e)(3)(ii)(A), so the per-se passive rule never applies and the 750-hour test is irrelevant. You still need material participation, but only that. How the short-term rental route works.
• A qualifying spouse. If one spouse can clear both tests, a joint return puts the freed-up losses against the household's income.
• Other passive income. A passive loss is not wasted. It offsets passive income now and carries forward, and suspended losses are generally released when you dispose of the activity. The benefit arrives later than the year you paid for the study, which is the honest trade.

How this interacts with a cost segregation study

The order of operations matters, and getting it backwards is the most common and most expensive mistake in this area.

A study decides how much depreciation you can take and when. Section 469 decides whether you can use it against the income you care about. No study changes your §469 status. The Tax Court put it almost exactly that way in Mirch: bonus depreciation changes the size of the deduction, not whether the loss is passive or non-passive.

So the sequence is: work out your participation position first, then decide on the study. If you are relying on REPS, the hours have to be real and documented for the year the deduction lands. If you cannot get there, the study may still be worth doing for a deferred benefit, but you should buy it knowing that.

Common questions

Does getting a real estate license help?

Not by itself. There is no licensing requirement in §469(c)(7), and holding a license does not create hours. Brokerage is a qualifying real property trade or business, so working as an agent generates qualifying hours, but the license alone does nothing.

Do I have to qualify every year?

Yes. It is an annual determination. You can be a real estate professional in one year and not the next, and the tests are applied to each tax year on its own facts.

Is there an income limit?

No. REPS has no income phase-out. The $25,000allowance that phases out between $100,000 and$150,000 of modified AGI is a different, narrower exception for passive rentals with active participation. Confusing the two is extremely common.

Can a full-time W-2 employee ever qualify?

Rarely, and only where the real property hours genuinely exceed the job's hours. A part-time or seasonal job changes the arithmetic; a 40-hour week usually does not. Be skeptical of anyone who tells you otherwise without asking how you spend your time.
