Real estate investors who claim Real Estate Professional Status (REPS) under IRC §469(c)(7) can deduct rental losses against ordinary income, including W-2 wages. That is a genuinely powerful tax position. It is also one the IRS watches closely, because the rules are specific, the documentation requirements are exacting, and the payoff for a successful challenge is large from the agency's perspective.
TL;DR: IRS scrutiny of REPS claims under IRC §469(c)(7) focuses on three areas: the size and pattern of rental losses claimed against W-2 income, the quality of the hour log, and proof that more than half of all personal services were in real property trades or businesses. After-the-fact, reconstructed logs with rounded entries and vague descriptions are the fastest path to a disallowed deduction. A real-time, contemporaneous log is the single best defense.
Written by the REPS Time team, real estate investors who track Real Estate Professional Status and short-term rental material-participation hours, grounded in IRC §469(c)(7) and current Treasury guidance.
What Makes the IRS Look at a REPS Claim in the First Place?
The IRS does not publish a checklist titled "reasons we audit real estate investors." What we do know, from Tax Court patterns and IRS examination guidance, is that certain filing profiles attract attention. A few of the most consistent ones:
Large rental losses against high W-2 income. This is the most reliable flag. When a return shows a six-figure salary alongside a substantial Schedule E loss, the combination is a direct challenge to the passive activity loss rules in IRC §469. Under the default rule, rental losses are passive and cannot offset wages. A REPS election says the taxpayer is exempt from that default. The IRS examines whether that exemption was actually earned.
Year-over-year loss patterns. A rental that produces paper losses every single year, especially after a cost segregation study, is not inherently suspicious. But a string of large identical losses with no apparent business trajectory can invite a closer look.
Mismatched return positions. Claiming REPS while also reporting a full-time W-2 job without any explanation raises an obvious question: when did these 750+ hours actually happen? The IRS can see your W-2 employer and how much you earned. If the numbers imply a 50-hour work week at your day job, the "more than half of personal services in real estate" test becomes very hard to explain without strong documentation.
Missing or inconsistent grouping elections. Under IRC §469(c)(7)(A), a real estate professional can elect to treat all rental activities as a single activity for material-participation purposes. If that election was not timely made and no late relief was sought under Rev. Proc. 2011-34, the taxpayer may need to prove material participation property by property. Each property then needs its own hour documentation.
The Two Tests You Have to Prove, Not Just Claim
REPS under IRC §469(c)(7) requires that both of these tests are met by the same individual (not a combination of spouses):
- More than 750 hours in real property trades or businesses in which the taxpayer materially participates.
- More than half of all personal services performed during the year are in those real property trades or businesses.
That second test trips up more investors than the first. If you have any job, consulting work, or active business outside of real estate, those hours count against you. Say you work 1,200 hours at a W-2 job. You would need more than 1,200 hours in qualifying real estate activity to clear the more-than-half bar. The 750-hour floor is a minimum, not a finish line.
The IRS will ask for documentation of both. The hour log covers the first test. Proving the second usually means reconstructing your full-year schedule, including all non-real-estate work, to show the ratio tips in real estate's favor.
For a thorough walkthrough of how both tests interact, the complete guide to Real Estate Professional Status covers the mechanics in detail.
What Gets Hour Logs Rejected: A Pattern from the Courts
Tax Court has ruled on REPS documentation cases many times, and the pattern is consistent. Here is a side-by-side look at what failing logs and passing logs tend to look like.
| What Gets Rejected | What Holds Up |
|---|---|
| Hours reconstructed after the audit notice arrived | Hours logged at or near the time the work happened |
| Rounded entries ("4 hours on Saturdays") | Specific start and end times for each task |
| Vague task descriptions ("property management") | Specific tasks: "showed unit 2B, responded to repair request, reviewed lease renewal" |
| "On call" time with no associated tasks | Actual time spent doing identifiable work |
| A single calendar with no backup | Log entries plus emails, texts, contractor invoices, or photos that corroborate timing |
The case of Almquist v. Commissioner is a clear example of what "ballpark guesstimate" hours look like to a judge. The court rejected the log and imposed a 20% accuracy-related penalty. Penley v. Commissioner had a similar outcome: rounded hours with no specific times were not enough.
The Hairston v. Commissioner case analysis on this blog walks through exactly how a log gets rejected and what the court wanted instead. It is worth reading before you decide your current tracking system is good enough.
One more rule that catches people off guard: investor-level activities do not count. Treas. Reg. §1.469-5T(f)(2)(ii) explicitly excludes time spent reviewing financial statements, studying the market, or arranging financing. Those activities feel like work. They are not qualifying hours.
A Worked Example: How the Numbers Play Out
Say you are a physician earning $350,000 in W-2 income. You own three rental properties and your CPA runs a cost segregation study that produces a $120,000 paper loss in year one, driven by accelerated depreciation on 5-, 7-, and 15-year components now eligible for 100% bonus depreciation under the One Big Beautiful Bill Act.
Without REPS, that $120,000 loss is passive. It cannot touch your $350,000 W-2 income. It carries forward until you have passive income or sell the property.
With REPS, that $120,000 offsets your ordinary income directly. At a 37% marginal federal rate, that is a $44,400 federal tax reduction in year one.
Now imagine the IRS examines that return. The examiner asks for your hour log. You pull together a spreadsheet you built from memory over a weekend after getting the audit notice. It shows 800 hours across the year, mostly in 4- and 8-hour blocks with descriptions like "property management" and "maintenance oversight."
The examiner compares those hours to your W-2, which shows $350,000 from a full-time medical practice. She notes that the log was created after the fact and that the entries are too vague to verify. She disallows the REPS election. The $120,000 becomes passive again. You owe $44,400 in taxes plus interest and potentially a 20% accuracy penalty on top.
The difference between that outcome and a clean audit is a real-time log with specific entries. That is not a small detail.
What "Contemporaneous" Actually Means
The IRS and Tax Court use the word "contemporaneous" to mean the log was created at or near the time the work was done. Not that same week. Not that same month from memory. At or near the time.
This does not mean you need a stopwatch running every minute. It does mean:
- You open your tracking tool or calendar before or immediately after a task.
- You record the date, the property, the specific task, and the start and end time.
- You do this consistently, not just in months where you happen to remember.
The guide to contemporaneous logs and material participation has a practical breakdown of what each entry should contain and how to handle edge cases like travel time and phone calls.
A purpose-built tool like REPS Time is designed specifically for this workflow: logging real estate hours in real time, tagging them by property and task type, and producing a report that reads the way an IRS examiner expects to see it.
The "More Than Half" Test Is Where Many Audits Actually Fail
Investors spend a lot of energy worrying about hitting 750 hours. That is worth worrying about. But the more-than-half test is where many audits fail quietly, because investors never ran the math on their non-real-estate time.
Here is a simple check. Add up every hour you worked outside of real estate during the year: your job, your consulting, your side business, any other professional activity. Call that number X. For REPS to hold, your real estate hours must exceed X. They also must exceed 750. The binding constraint depends on your situation.
If you have a W-2 job and logged 780 real estate hours, but you worked 900 hours at your employer, you do not qualify. The 750-hour threshold is met. The more-than-half test is not.
Investors with demanding careers who are still going for REPS need to do this arithmetic before filing, not after receiving an IRS notice. If the numbers are close, document non-real-estate hours carefully too, because the IRS can ask for both sides of the ratio.
Three Practical Steps That Reduce Audit Risk
These are not legal compliance recommendations. They are documentation practices that Tax Court opinions consistently treat as meaningful.
Log in real time. Every qualified study on this topic points to the same conclusion: after-the-fact reconstruction fails in court far more often than real-time logs. Build the habit early in the year.
Keep corroborating records. Emails to tenants, text threads with contractors, invoices, repair photos, bank transfers, and calendar entries all give an examiner something to cross-reference against your log. A log that is never corroborated by anything else is harder to defend.
Run the more-than-half math before you file. Know your non-real-estate hours for the year. Make sure the ratio works. If it does not, the honest answer is that REPS was not met that year, and carrying the loss forward is better than defending a position that does not hold up.

Frequently Asked Questions
Does having a property manager hurt a REPS claim? Not automatically. A property manager handles day-to-day tasks, but the investor can still log qualifying hours for work they personally perform: tenant screening, lease review, capital expenditure decisions, and contractor oversight. The issue is that fewer personal hours are usually available when a manager is in place, which makes hitting the 750-hour threshold harder. See the REPS with a property manager post for more on this.
Can my spouse's hours count toward the 750-hour test? No. IRC §469(c)(7) requires that one spouse individually meets both the 750-hour test and the more-than-half test. Spouses cannot pool hours to qualify for REPS itself. They can, however, combine hours when measuring material participation on a specific activity under IRC §469(h)(5). These are two different questions with two different answers.
What happens if I forgot to make a grouping election? Under IRC §469(c)(7)(A), a real estate professional can elect to treat all rental activities as a single activity. If you missed it in a prior year, Rev. Proc. 2011-34 provides a late-filing procedure. Without that election, you may need to prove material participation separately for each property, which is a much higher documentation burden.
Do IRS auditors ask for both sides of the more-than-half test? Yes. Demonstrating 750+ real estate hours is necessary but not sufficient. An examiner can and often does ask how many hours you worked in non-real-estate activities. If your W-2 income implies significant non-real-estate time, the burden of proving the ratio falls on you.
Does Tax Court ever uphold a REPS claim based on a reconstructed log? Rarely, and only when the reconstruction is supported by strong corroborating evidence, such as contractor invoices, emails, and calendar entries that independently confirm the timing and nature of the work. Courts have repeatedly rejected logs that are supported only by the taxpayer's own testimony. Almquist and Penley are the standard examples.
Bottom Line
If you are claiming REPS, the audit question is not whether you did the work. It is whether you can prove it. Build your log now, in real time, with specific entries. Run the more-than-half math before filing. Keep corroborating records that give an examiner something to verify against. The IRS does not audit taxpayers because they claim REPS. It audits taxpayers whose records cannot support the claim they made.
