Bonus Depreciation & REPS: Maximizing the 100% Bonus Depreciation with Qualifying Hours

The combination of 100% bonus depreciation and Real Estate Professional Status (REPS) represents one of the most powerful tax strategies available to high-income investors today. For W-2 earners, physicians, attorneys, and business owners with substantial real estate holdings, this pairing can transform what would otherwise be trapped passive losses into immediate, active income offsets.

But here's the catch: the IRS doesn't hand out these benefits casually. The rules are precise, the documentation requirements are strict, and the consequences of getting it wrong can be severe. This article walks through what actually qualifies for 100% bonus depreciation, how the deduction gets unlocked, and — most importantly — how to document your qualifying hours in a way that survives scrutiny.

One thing to flag before we start, because it's the most common mistake in planning right now: the trigger for the 100% rate is the date you acquired the property, not just the date you placed it in service. That distinction decides whether your deduction is 100% or 20%, and a lot of published guidance still gets it wrong.

The Power of Bonus Depreciation + REPS

What is Bonus Depreciation?

Bonus depreciation is an accelerated depreciation method that allows you to immediately deduct the cost of qualifying property in the year it's placed in service. Instead of spreading the deduction over the asset's recovery period — say, 5 or 7 years — you take it upfront.

The landscape shifted in 2025. Under the TCJA, bonus depreciation was phasing down: 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026, and zero after that. Section 70301 of the One Big Beautiful Bill Act (P.L. 119-21), enacted July 4, 2025, repealed that schedule and restored 100% bonus depreciation permanently. There is no sunset date.

The Date That Decides Your Rate

The 100% rate applies to qualified property acquired and placed in service after January 19, 2025. Acquisition is generally the date a written binding contract is entered into — and property is not treated as acquired after January 19, 2025 if a written binding contract was in effect before January 20, 2025.

That's the part worth reading twice. A property you contracted for in November 2024 and closed on in 2026 is still on the old TCJA schedule. It doesn't matter that you placed it in service well after the cutoff.

Acquisition date	Placed in service	Bonus rate
After Jan 19, 2025	After Jan 19, 2025	100%
On or before Jan 19, 2025	During 2025	40%
On or before Jan 19, 2025	During 2026	20%
On or before Jan 19, 2025	2027 or later	0%

If you've read that the pre-cutoff rate was 80%, that was the 2023 figure. For 2025 the phase-down rate was 40%.

IRS Notice 2026-11, released January 14, 2026, provides interim guidance and confirms the IRS will apply the existing Reg. §1.168(k)-2 framework with the dates updated — including the written binding contract rules. Taxpayers can rely on it until proposed regulations are finalized. The notice also preserves an election to claim a reduced 40% deduction instead of 100% for the first tax year ending after January 19, 2025, and the ability to elect out of bonus depreciation entirely for any class of property.

That last point matters more than it sounds. Bonus depreciation is mandatory unless you elect out. If a large first-year deduction would create a net operating loss you can't use efficiently, or wipe out income you'd rather have taxed at lower brackets, electing out is a real planning option — and it's a decision, not a default.

Why REPS Is the Key to Unlocking It

Here's where most investors miss the opportunity. Bonus depreciation on rental property generates losses, often substantial ones. But under the passive activity loss rules in IRC §469, rental losses are generally passive. They can only offset passive income. If your income comes from a W-2 job or an active business, those losses sit idle and carry forward.

Real Estate Professional Status, defined under IRC §469(c)(7), changes that. When you qualify and materially participate, the activity is no longer per se passive, and the losses can offset wages, business income, and capital gains.

There's also a second path that gets less attention and is far more achievable for most high earners: the short-term rental exception. Under Temp. Reg. §1.469-1T(e)(3)(ii)(A), a property with an average period of customer use of seven days or less isn't a rental activity at all. No 750 hours required — just material participation. More on that below, because it's the version of this strategy that actually works for a full-time professional.

What Qualifies for 100% Bonus Depreciation

Bonus depreciation applies to tangible property with a MACRS recovery period of 20 years or less. In real estate, a cost segregation study typically identifies:

• Appliances — refrigerators, stoves, dishwashers
• Carpeting and certain flooring
• Decorative lighting and dedicated electrical or plumbing serving specific equipment
• Furniture and fixtures
• Specialized equipment such as pool or fitness equipment
• 15-year land improvements — paving, sidewalks, fencing, site utilities, certain landscaping

One clarification for residential investors, because this appears on nearly every list you'll find and shouldn't be on yours. Qualified Improvement Property is defined for improvements to the interior of nonresidential real property. If you own residential rentals, QIP isn't part of your analysis. Lists that include "certain non-structural building improvements" without that caveat will lead you to expect a deduction you don't have.

A genuine expansion worth knowing: bonus depreciation applies to used property, provided it's new to you and the acquisition requirements are met. You can buy a turnkey rental, run a cost segregation study, and take 100% on the qualifying components. Nothing has to be newly built.

The Role of Cost Segregation

Without a study, a building is depreciated over 27.5 years for residential or 39 for commercial. A cost segregation study uses engineering analysis to reclassify components into 5-, 7-, and 15-year categories, and under 100% bonus those become a first-year deduction.

How much gets reclassified depends on the property. Residential rentals commonly land in the 20–30% range of depreciable basis; properties with heavy site work or build-out can run higher. Be skeptical of anyone quoting a percentage before looking at the property. Expect to pay roughly $4,000–$8,000 for a study on a single-family rental, with engineer-based studies at the higher end.

The IRS publishes a Cost Segregation Audit Techniques Guide (Publication 5653) setting out the thirteen elements of a quality study. It's written for examiners, but it's the clearest available statement of what the IRS expects — worth skimming before you hire a firm, and worth asking a prospective firm whether their methodology matches it.

For the full walkthrough, see Cost Segregation for REPS Investors.

What Is Real Estate Professional Status?

REPS isn't a designation you apply for. It's a factual determination you make each year, and you have to re-establish it every year — hours don't carry forward.

Two requirements under IRC §469(c)(7)(B):

1. You perform more than 750 hours of service in real property trades or businesses in which you materially participate.
2. More than half of all personal services you perform in any trade or business are in those same real property trades or businesses.

The second requirement is where high-income professionals get stopped. Work 2,000 hours at a medical practice and you need more than 2,000 hours in real estate — not 750. The hour floor is the easy part; the ratio is the wall.

On spouses, a correction to guidance that appears widely, including in an earlier version of this article. Married couples filing jointly cannot combine hours to reach 750. IRC §469(c)(7)(B) provides that on a joint return the requirements are satisfied "if and only if either spouse separately satisfies such requirements." One spouse has to clear both tests alone.

Spousal hours do count, for a different purpose: under §469(h)(5), a spouse's participation counts toward the taxpayer's material participation in an activity. Details in Can Married Couples Combine Hours to Qualify for REPS?

A real property trade or business includes rental real estate, development, construction, management, brokerage, and leasing. Publication 925 covers the passive activity rules in detail.

Material Participation: The Second Hurdle

Qualifying as a real estate professional is not the finish line. Section 469(c)(7) removes the per se passive rule; it doesn't remove the requirement to materially participate. The Ninth Circuit made that explicit in Gragg v. United States, 831 F.3d 1189 (9th Cir. 2016), where a licensed full-time real estate agent met both hour tests and still lost her rental losses because she couldn't substantiate participation.

The seven tests are in Temp. Reg. §1.469-5T(a). The ones that matter most here:

• Test 1: more than 500 hours in the activity.
• Test 3: more than 100 hours, and no other individual — including employees, property managers, or other owners — performs more services than you.
• Test 7: facts and circumstances showing regular, continuous, and substantial participation. Courts read this one narrowly, and it isn't a fallback you should plan around.

For most investors Test 3 is the practical target. You don't need to do every task yourself — you need to be the most involved person. That "no one else does more" clause is what the grouping election helps with, and what a full-service property manager destroys.

Example: How the Deduction Actually Gets Used

Let's make this concrete, and let's build the example so it holds together — because the version that circulates widely does not.

Dr. Sarah is a radiologist earning $400,000. In March 2026 she buys a $1.2 million short-term rental, and a cost segregation study reclassifies $240,000 to 5- and 7-year property. Under 100% bonus, that's a $240,000 first-year deduction.

Now: can she use it?

Not through REPS. She works roughly 2,000 hours as a radiologist. To satisfy the more-than-half test she'd need to log more than 2,000 hours in real estate — about 40 hours a week on top of her practice. Any example that has a full-time physician qualifying for REPS on 750 or 800 hours is describing something that can't happen, and if you've seen one, that's the flaw.

Through the STR exception, yes. Her property averages four-night stays, so under §1.469-1T(e)(3)(ii)(A) it isn't a rental activity. She needs material participation, not REPS. She handles guest communication, booking, pricing, and vendor coordination herself, logging 140 hours; her cleaner logs 60. She clears Test 3 — more than 100 hours, and more than any other individual — and the losses are non-passive.

Here's the tax effect. Her taxable income drops from $400,000 to $160,000. Running both figures through the 2026 single-filer brackets, federal tax falls from roughly $108,800 to about $31,000 — around $77,800 in savings on a $240,000 deduction.

That's an effective rate of about 32%. The common presentation multiplies $240,000 by 37% and prints $88,800, which is wrong twice over: the 37% bracket doesn't begin until $640,600 of taxable income for single filers in 2026, and a deduction this large pushes you down through several brackets, so the last dollars come off at 24%. Seventy-eight thousand dollars is a superb outcome on a study that cost her $6,000. It just isn't eighty-nine.

This ignores state income tax, which would increase the benefit, and any at-risk or basis limitations, which could reduce it. Run your own numbers with your CPA.

One more thing about Sarah's situation: qualification is annual. Whether she materially participates in 2027 is a fresh question with a fresh answer, and a year where she travels more or hands the property to a full-service manager is a year the losses go passive.

Qualifying Hours: What Counts

The statute doesn't define "services in real property trades or businesses" exhaustively, but the regulations and the case law draw a usable line. Qualifying activities generally include:

• Property management and oversight
• Tenant and guest communication, lease negotiation
• Vendor coordination for repairs and maintenance
• Maintenance oversight, and hands-on maintenance you perform
• Operational bookkeeping tied to the properties
• Property visits and inspections
• Operating decisions — pricing, whether to renovate

Investor-capacity work is the category that costs people deductions. Under Temp. Reg. §1.469-5T(f)(2)(ii), work you do as an investor doesn't count toward material participation unless you're directly involved in day-to-day management. The regulation specifically names reviewing financial statements or reports on operations, preparing analyses of the finances for your own use, and monitoring operations in a non-managerial capacity.

The practical split: invoicing, paying vendors, reconciling the operating account, and assembling records for your tax preparer are operational. Reviewing your P&L to see how the property performed is not. Setting next season's rates is operational. Running comps on a property you might buy is not.

This is what sank the taxpayer in Hakkak v. Commissioner, T.C. Memo. 2020-46. Beyond finding his handwritten calendars too vague, the court held that even if the hours had been substantiated, his activities were "more akin" to an investor's than an operator's. Real hours, documented, and they still didn't count.

Based on REPSShield platform data from 418 users logging nearly 30,000 hours across 684 properties, the most commonly tracked qualifying activities are vendor coordination, tenant communication, and financial record-keeping — together accounting for over 55% of logged entries. Long-term rentals dominate the platform at 552 properties versus 130 short-term, which tells you the strategy runs both ways, though the long-term path demands the higher hour count.

Documentation

Contemporaneous documentation is the whole ballgame in a REPS or STR examination, and the leading case is more specific than most summaries suggest.

In Moss v. Commissioner, 135 T.C. 365 (2010), the taxpayer worked full-time at a nuclear plant and documented 645.5 hours on his rentals — short of 750. He argued that time spent "on call" for the properties should close the gap. The court held that §469(c)(7)(B)(ii) requires services to be performed, not to be available to be performed. Availability isn't participation. Without those hours he lost REPS, and the court sustained an accuracy-related penalty on top of the deficiency. The court also noted that Moss had reconstructed his hours from a calendar after the year closed, and that the regulations don't permit a post-event "ballpark guesstimate" — a phrase from Bailey v. Commissioner, T.C. Memo. 2001-296.

Penley v. Commissioner, T.C. Memo. 2017-65 shows the other failure mode. The taxpayer had a log — claiming 2,520 real estate hours on top of a 2,194-hour job. The court found the total implausible, noting it left no time for meals or family, and rejected the log entirely. Too much documentation, badly constructed, is its own risk.

Note that Reg. §1.469-5T(f)(4) doesn't require daily logs. Participation may be established by any reasonable means, including appointment books, calendars, or narrative summaries. The flexibility is about format, not timing.

The difference in practice: "property management, 8 hours, June" is worth very little. "June 15, 2026: 2.5 hours coordinating with HVAC vendor for condenser replacement at 123 Main St. unit 3, including two calls and estimate review" is worth a great deal.

Common Pitfalls

Failing material participation after clearing the hours

Meeting 750 hours and then failing Test 3 is a common way to lose. A full-time property manager who out-hours you breaks it. So does owning several properties without a grouping election, since you'd need to establish participation in each one separately.

Reconstructing at year end

The temptation to estimate in December is strong. Resist it — that's precisely the Moss fact pattern. Across the REPSShield platform, 47.8% of entries are manual, 26.6% come from Gmail, and 9.7% from calendar. Automated capture doesn't guarantee any outcome in an examination, but it does avoid reconstruction, which is the specific thing courts reject.

Misunderstanding the grouping election

The election under Reg. §1.469-9(g) lets you treat all interests in rental real estate as a single activity. Without it, each property is separate.

Two mechanics worth getting right: the election is made by attaching a statement to your return, not on Form 8582, by the due date including extensions. And it's binding for future years unless circumstances materially change — late-election relief exists under Rev. Proc. 2011-34 but isn't automatic.

If you own short-term rentals, note that a seven-day-or-less property isn't a rental activity and therefore can't be included in a §1.469-9(g) election. Multiple STRs can be grouped, but under Reg. §1.469-4(c) as trade or business activities forming an appropriate economic unit, disclosed under Rev. Proc. 2010-13.

Counting availability

Worth its own line because it's the correction that most often moves someone from "I'm comfortably over 750" to "I'm at 500." If your mental tally includes time you were reachable, subtract all of it.

Strategic Planning

When to Run the Study

The usual timing is the first year of ownership or after significant renovation. But there's a real question of whether to run it at all this year, and it turns on whether you can use the deduction.

If you won't qualify for REPS or the STR exception this year, the bonus depreciation generates a passive loss that suspends. Not lost — under §469(g) suspended losses are released in full when you dispose of your entire interest in a fully taxable transaction to an unrelated party — but deferred, possibly for years.

To correct something stated in an earlier version of this article: you can apply a cost segregation study to a property you've already owned. A look-back study is performed and the cumulative catch-up depreciation claimed in the current year as a §481(a) adjustment via Form 3115. You do not have to amend prior returns, and you are not locked out because you didn't do it at purchase.

What doesn't change is your bonus rate. That's fixed by when you acquired the property. A 2023 acquisition gets the 2023 rules no matter when you run the study.

Year-Round Tracking

You can't wait until December. For a W-2 professional working 2,000 hours, the more-than-half test requires more than 2,000 real estate hours — roughly 40 hours a week on top of the day job. For most people that isn't feasible, which is why the workable configurations are narrow: one spouse working real estate as their primary occupation, a genuine career transition, or the STR exception, which asks for 100+ hours rather than 750.

Being honest about which of those describes you is the most valuable planning step in this entire article. REPSShield platform data shows users averaging 1.90 hours per entry, with the heaviest logging from March through August at 1,200–1,500 entries monthly. Consistent capture across the year is what the successful pattern looks like.

Conclusion

With 100% bonus depreciation permanently restored, the deduction side of this strategy is as strong as it has ever been. Which shifts where the risk sits. The constraint is no longer the tax code — it's whether you can prove you qualified to use the deduction.

Three things have to line up: a property acquired after January 19, 2025 (or a look-back study on one you already own), a path to non-passive treatment through REPS or the STR exception, and contemporaneous documentation of the hours behind it. Miss any one and the strategy doesn't work.

Moss had 645.5 documented hours and lost. Penley had a log and lost because nobody believed it. Hakkak had calendars, emails, leases, and bank statements, and the court still found his hours looked like an investor's. None of them lost because they weren't working.

Start tracking before you order the study, not after.

REPSShield captures your real estate hours as the work happens — from Gmail, calendar, geofenced property visits, and manual entry — with the date, property, activity type, and duration attached to each entry, and operational work logged separately from investor-capacity work.
