Real estate professional status and the IRS

By Max Medvedev · 6 Aug 2026

There is no form, so the return is the claim

Nothing on a return announces real estate professional status. No election accompanies it, no box confirms it. What appears is the consequence: rental losses treated as non-passive, offsetting wages or business income rather than waiting on Form 8582.

That treatment is the claim, and it is tested later against records you either kept or did not. The status is unusual in that respect — most tax positions are documented when taken, and this one is documented all year by someone who may not realise they are building the evidence.

Three separate things have to hold up, and taxpayers usually prepare only the first:

1. The 750 hours in real property trades or businesses in which you materially participate.
2. The denominator — all your other trade-or-business hours, which decide the more-than-half test.
3. Material participation in the activity itself, per property, unless the §1.469-9(g) election aggregated them.

What the status is and what it never provides covers why the third is separate; Gragg v. United States is the holding.

The standard the regulations actually set

Reg. §1.469-5T(f)(4) is more generous than its reputation. Participation may be established by any reasonable means, and the regulation says explicitly that contemporaneous daily time reports are not required. Appointment books, calendars and narrative summaries are named as acceptable.

The courts have then spent thirty years narrowing what "reasonable" tolerates, and the operative sentence comes from Moss v. Commissioner, 135 T.C. 365 (2010): the regulations "do not allow a post-event ballpark guesstimate." The case in detail.

So the practical standard is neither a punch clock nor a summary written in April. It is a record made close enough to the work that it carries detail a reconstruction cannot invent.

What has failed, and the specific tell in each

The losses are more instructive than the wins, because each turns on a single identifiable habit.

Mirch is the one to read twice. The court agreed the property met the seven-day test — the classification was won — and the entire deduction was still disallowed, because credible participation came in under 100 hours once on-call time and round-number entries were removed. Winning the label and losing the year is the characteristic failure in this area.

There is also Eger v. United States, Ninth Circuit 2020, for a structural version of the same lesson: a management contract is not a lease, and the manager cannot be recharacterised as your tenant to make the arithmetic work.

What has survived

Four taxpayer wins, and none of them required anything exotic:

• Windham, T.C. Memo 2017-68 — a credible contemporaneous record with corroboration, alongside a part-time job.
• Birdsong, T.C. Memo 2018-148 — detailed spreadsheets plus credible testimony met the reasonable-means standard.
• Zarrinnegar, T.C. Memo 2017-34 — a full-time dentist won on a detailed log kept as the work happened.
• Leyh, T.C. Summ. Op. 2015-27 — a clean log earned the benefit of the doubt on omitted travel.

The pattern is consistent. A record written while the work happened, specific about what was done, with a witness or a document beside it. Zarrinnegar is the useful one to hold onto: a full-time job did not defeat the participation claim. It defeats the more-than-half test for the status, but participation is a different question and it was won on the log.

The habits that decide it

Falling out of those cases, and applying whether or not you hold the status:

• Contemporaneous beats reconstructed. Every win rests on it; the clearest losses rest on its absence.
• Round numbers are a red flag. Real work does not take exactly two hours fourteen times.
• Log actual tasks with start and stop times, sized to the task.
• On-call and available time is worth nothing. Moss, then Mirch.
• Investor and bookkeeping hours generally do not count as participation.
• If you use a manager, log the manager's hours too. Pohoski won one property and lost another on exactly this — test 3 asks whether you did more than any other individual, and you cannot show it without their number.
• Document your other job's hours. That is the denominator of the more-than-half test, and leaving it vague weakens the whole position.
• Corroboration wins — photos, invoices, messages, receipts.
• Quality over quantity. 800 defensible hours beat 1,200 inflated ones. Over-claiming invites a court to discard the record entirely, which is what happened in Penley and Hairston.

How to build the record walks through it as a practice rather than a list.

Where the software fits

None of this needs a product. Spreadsheets won Birdsong.

What a tool changes is the timing, which is the thing the cases actually turn on. An entry written on the drive home carries a timestamp, a property and a photo that a April reconstruction cannot produce afterwards. That is the difference between the wins and the losses in the table above, and it is not a difference in effort.

Run the year in the estimator: it applies all seven material participation tests, flags the hour types the cases have rejected, and cites the rule behind each verdict. The material participation test runs the participation half on its own.
