Quick note before we get into it — this list just crossed 300 people. Thank you for being here.

Looking at who's actually reading: real estate agents, investors, flippers, property managers, contractors, small business owners. Pretty much everyone who touches a deal from a different seat at the table. That's exactly why I try to write these so there's something useful in it no matter which seat is yours.

Alright — onto today's issue.

The myth “As long as I spend more than 100 hours on my short-term rental, I qualify for the STR tax strategy.”

What's actually true The short-term rental strategy is real, and it works — when it's done right. Buy a property, rent it out in stays of 7 days or less, materially participate in running it, and the losses (often accelerated hard through a cost segregation study) can offset your W-2 income instead of getting stuck as passive losses. That's the whole appeal.

The part that trips people up is: material participation. And a real Tax Court case shows exactly how.

The case In Lucero v. Commissioner (2020), a taxpayer owned a short-term rental in California. He hired a property-management company to handle much of the day-to-day operation, including advertising, rent collection, cleaning, landscaping, repairs, and guest issues.

He still remained involved. He approved larger expenses, set rental rates, purchased supplies, and traveled to the property several times each year to perform or oversee maintenance.

During the IRS examination, he reconstructed a time log showing 267 hours for one year and 273 hours for the next.

The Tax Court still rejected his material-participation position.

Three things hurt him.

• The log was built after the fact. It wasn't kept in real time, and courts consistently give reconstructed logs far less weight than contemporaneous records.
• A lot of the hours didn't count. Paying bills, reviewing statements, and prepping for tax season are "investor" activities under the regulations — they don't count toward material participation, no matter how many hours they take.
• Even the hours that were real didn't settle it. The court noted that even taking his log at face value, he never showed he worked more than the management company did — and one of the material participation tests requires exactly that comparison.

The result: the deduction was reversed, and he owed back taxes, penalties, and interest on top of it.

Why this matters for you This isn't a reason to avoid the STR strategy. It's a genuinely good tool when the facts support it. It's a reason to take "material participation" seriously instead of treating it as a box to check after the fact.

Do you want want to offset active income — whether it's a W-2, a 1099, or your own business — with STR? Here's how to do it:

Key takeaways

• Time logs built during an audit carry far less weight than logs kept in real time, throughout the year
• Investor-type activities — bookkeeping, reviewing statements, tax prep — don't count toward your hours
• If you use a property manager, you need to be able to show your time exceeds theirs, not just clear 100 hours on your own
• Getting this wrong doesn't just cost you the deduction — it can mean back taxes, penalties, and interest stacked on top

The bottom line The STR strategy works. But "I self-manage and I'll track my hours" isn't a plan — it's an invitation for exactly what happened here. If you're running (or considering) this strategy, it's worth having someone review the details before the IRS does it for you.

Flip it or rent it? The IRS taxes them so differently that picking wrong can cost you self-employment tax you never saw coming.
