Does the IRS require a daily log for material participation?

Treasury Regulation § 1.469-5T(f)(4) permits any reasonable means of proof, but Tax Court judges consistently reject post-event 'ballpark guesstimates'. Contemporaneous records backed by receipts, calendars, or photos carry the strongest weight.

Can investor hours count toward the 750-hour REPS threshold?

No. Under Treas. Reg. § 1.469-5T(f)(2)(ii), reviewing financial statements or analyzing market trends in an investor capacity does not count toward material participation.

Why should I log hours worked by cleaners and contractors for my STR?

Under Treasury Regulation § 1.469-5T(a)(3) (the 100-hour STR loophole test), you must work more than 100 hours and more hours than any other individual. Logging third-party hours—including cleaners and repair technicians—is essential proof that no single contractor worked more hours on that property than you.

Date	Person / Participant	Property	Activity (Facts Only)	Hours	Corroborating Proof	Audit Status

2026-09-12	Third-party contractor / Plumber (example)	Example Property A (STR)	Replaced leaking sink trap and tested drain	1.25	Paid plumbing invoice #104	Contractor (100h Rule Benchmark)
2026-09-15	Cleaner - Person 1 of 2 (example)	Example Property A (STR)	Turnover cleaning and linen service between guests	2.50	Paid cleaning invoice #218	Contractor (100h Rule Benchmark)
2026-09-20	Owner (example)	Portfolio	Browsing real estate listings and reading forum posts	3.00	None (investor time disallowed under Reg. § 1.469-5T)	Disallowed (Investor)

Why log third-party contractor and cleaner hours? Under Treasury Regulation § 1.469-5T(a)(3) (the 100-hour STR loophole test), you must participate for more than 100 hours and your participation must not be less than any other individual. Logging contractor and cleaning hours provides contemporaneous proof to your CPA that no single vendor exceeded your logged hours.

The 7 Columns Required for Audit Defense

Under Treasury Regulation § 1.469-5T(f)(4), an audit-ready log should include these essential fields:

1
Date
Specific date the work occurred (no monthly lump sums)
2
Property
Identifies the specific rental unit or elected activity group
3
Participant
Taxpayer, spouse, or contractor (spouse hours cannot combine for REPS 750h; contractor hours prove the 100h STR comparison)
4
Specific Activity
Factual task description (e.g., 'repaired water heater', not 'maintenance')
5
Duration
Actual decimal hours spent (e.g., 1.5 hrs, not estimated days)
6
Category
Operational or management vs. disallowed investor research
7
Corroborating Proof
Reference to receipt, photo, GPS mileage, or contractor invoice
