Tax rules

Material participation,
plain English.

The 7-day rule, in one sentence. Under Treas. Reg. §1.469-1T(e)(3)(ii)(A), a rental activity where the average period of customer use is 7 days or less is not treated as a rental activity for purposes of the passive loss rules. That carve-out is what creates the so-called STR loophole: short-term rentals with a 7-day-or-less average stay (vacation rentals, Airbnbs, VRBOs) escape the §469 rental presumption, so material participation alone — no Real Estate Professional Status required — is enough to make the losses non-passive and usable against W-2 income.

The material participation test (IRC §469) determines whether your rental losses are passive (limited to passive income) or non-passive (free to offset active income like W-2 wages and business income). For short-term rental owners, meeting one of the seven IRS tests can unlock tens of thousands in Year-1 deductions — what's commonly called the "STR loophole."

The seven IRS tests

  1. 500-hour test: 500+ hours/year on the activity
  2. Substantially all test: You do substantially all the work
  3. 100-hour + nobody does more test: 100+ hours and nobody else (including pros) does more
  4. Significant participation activities: Combined 500+ hours across multiple SPAs
  5. 5-of-10 years test: Materially participated 5 of last 10 years
  6. Personal service activity: Personal-service business, materially participated 3+ prior years
  7. Facts and circumstances: Catch-all (rarely usable)

Why STR is different from long-term rental

Long-term rentals are presumed passive under §469 — even if you spend hundreds of hours on the property, the losses are passive unless you qualify as a Real Estate Professional (REPS). STRs with average guest stays of 7 days or less are NOT considered rental activities under §469, so the §469 rental rules don't apply. Material participation alone (no REPS needed) is enough to make losses non-passive.

How to document hours

The IRS requires contemporaneous time logs — created as activities happen, not reconstructed at tax time. Track every hour you spend on the rental: cleaning, guest communication, maintenance, supply runs, marketing, bookkeeping. Spouse hours count under Treas. Reg. §1.469-5T(f)(3), regardless of ownership.

Frequently asked

What counts as 'average period of customer use'?

Average period of customer use is total days rented divided by the number of separate rentals. A property rented 250 days across 50 separate guest stays has an average period of customer use of 5 days — well under the 7-day threshold. The IRS calculates this per property, per tax year, under Treas. Reg. §1.469-1T(e)(3)(iii). Properties with consistent week-or-less stays (vacation rentals, Airbnbs, VRBO) reliably qualify; properties with month-long winter rentals can push the average above 7 days and lose the exception for that tax year.

Do I need Real Estate Professional Status (REPS) for STR cost segregation?

No — and that's the entire point of the §1.469-1T(e)(3)(ii)(A) exception. REPS requires 750+ hours/year in real estate trades or businesses AND that real estate be your primary activity (essentially impossible for a W-2 earner). The STR exception bypasses REPS entirely: if your average rental period is 7 days or less and you materially participate (one of the seven IRS tests), your STR losses are non-passive without needing REPS. This is why the STR strategy works for doctors, lawyers, and tech workers with full-time W-2 jobs.

What's the difference between the 7-day rule and the 30-day rule?

Both come from Treas. Reg. §1.469-1T(e)(3)(ii). The 7-day rule (subsection A) treats activities with average customer use of 7 days or less as non-rental — this is the standard STR exception. The 30-day rule (subsection B) covers activities with 30-day-or-less average use AND substantial personal services provided. The 'substantial services' bar is hotel-level: daily housekeeping, concierge, on-site staff. Most Airbnb hosts don't meet it. For practical purposes, the 7-day rule is what STR owners rely on; the 30-day rule applies mainly to hotels and B&Bs.

Does my spouse's time count toward material participation?

Yes. Under Treas. Reg. §1.469-5T(f)(3), participation by a taxpayer's spouse counts as participation by the taxpayer, regardless of whether the spouse has an ownership interest in the activity or files a joint return. Self-managing couples often pass Test 3 (the 100-hour test) easily: if each spouse contributes 60 hours of management work per year, the combined 120 hours exceeds the 100-hour threshold. Both spouses should track hours in the same log.

Will the IRS accept an Excel log, or do I need special software?

Excel is fine. The IRS does not require a specific format — what matters is that the log is contemporaneous (created as activities happen) and detailed (date, duration, specific activity description). A dated spreadsheet with task descriptions, cross-referenced to email timestamps and Airbnb message logs, is a standard format that holds up under audit. The free Excel template linked above includes the auto-calculated thresholds that make this easier to maintain.
