The STR Tax Advantage Guide

Educational information from the Wyo Stays team — not tax or legal advice. The rules below are real but fact-specific and change with each tax year. Everything here should be confirmed with a CPA who knows short-term rentals before you rely on it. We are a property brokerage, not your accountant.

The one idea that changes everything

Most people think all rental real estate is "passive." That matters because passive losses can normally only offset passive income — not your W-2 salary or business profits.

Short-term rentals can be the exception. Under the right facts, an STR is not treated as a rental activity at all for this test — which can make its losses non-passive, potentially offsetting active income. Paired with cost segregation and bonus depreciation, that's how sophisticated owners generate a large paper loss in year one against a property that's actually cash-flow positive.

This is why serious investors care about the STR designation far more than the nightly rate. Let's break down each piece.

Part 1 — The "STR loophole": why it isn't passive

The tax code has a specific carve-out. A rental generally escapes the "rental activity" (automatically passive) box when the average period of customer use is 7 days or less — which describes most vacation rentals.

But escaping "passive" isn't automatic. You also have to materially participate. The most common ways owners meet material participation:

• 500-hour test — you spend 500+ hours on the activity during the year, or
• Substantially-all test — you do substantially all the work the activity requires, or
• 100-hour test — you spend 100+ hours and no one else (including a manager or cleaner) spends more than you.

The catch most owners miss: if you hand everything to a full-service manager and a cleaning company, they may out-hour you — which can blow the 100-hour test. The 500-hour and substantially-all tests don't depend on comparing to others, which is why hours documentation is everything. (The downloadable version of this guide includes a material-participation hours log built for exactly this.)

This is the tension every hands-off owner has to navigate with their CPA: the tax benefit rewards involvement, while your sanity rewards delegation. There are legitimate structures for both — but only your CPA can tell you which applies to your facts.

Part 2 — Cost segregation: front-loading depreciation

Normally you depreciate a building slowly (residential rental over 27.5 years; many STR structures are argued over 39 years as transient lodging — your CPA decides which applies to your facts).

A cost segregation study breaks the property into its components — appliances, flooring, cabinetry, landscaping, certain electrical and plumbing tied to equipment — and reclassifies them into much shorter recovery periods (5, 7, and 15 years). Shorter recovery period = much bigger deductions in the early years.

On a typical property, a cost seg study commonly reclassifies 20–35% of the building's value into those short-life buckets. On a $600,000 property, that can mean six figures of accelerated depreciation available up front.

Part 3 — Bonus depreciation: the multiplier

Bonus depreciation lets you deduct a large percentage of those short-life (under-20-year) assets immediately instead of spreading them out. The bonus percentage has been changing year to year as legislation phases it up and down, so the exact figure for your purchase year is a "confirm with your CPA" item.

Put the three pieces together:

1. STR qualifies as non-passive (7-day-average + material participation), so
2. Losses can offset active income, and
3. Cost segregation creates a large pile of short-life assets, which
4. Bonus depreciation lets you deduct a big chunk of in year one.

That's the machine. A cash-flow-positive cabin can still throw off a substantial first-year paper loss that reduces tax on other income — legally, when the facts line up.

Part 4 — The everyday deductions people leave on the table

Even without the advanced moves, STR owners routinely under-deduct. Common Schedule E categories:

• Cleaning & turnover, supplies & consumables, restocking
• Management fees, channel fees, booking software
• Repairs & maintenance, lawn/snow, pest control
• Utilities, internet, streaming, smart-home subscriptions
• Insurance (the commercial STR policy)
• Mortgage interest, property taxes
• Furnishings & décor (often bonus-depreciable)
• Mileage / travel to the property for management
• Professional fees (CPA, attorney, this exact kind of planning)
• A portion of your phone and home office, where it qualifies

The downloadable Schedule E cheat sheet in this guide's PDF lists them with notes on documentation.

Part 5 — Wyoming's own advantage

Layered on top of the federal picture, Wyoming has no state personal income tax. For an owner, that means the STR's income isn't hit by a state income tax the way it would be in most states — and the federal depreciation strategy isn't partially clawed back at the state level. It's one more reason Wyoming property is structurally attractive to investor-owners, independent of the nightly rate.

Your STR tax-readiness checklist

1. ☐ CPA who specifically understands STR taxation engaged before year-end
2. ☐ Average-stay length tracked (are you actually ≤7 days?)
3. ☐ Material-participation hours logged contemporaneously (not reconstructed in April)
4. ☐ Cost segregation study evaluated for the purchase year
5. ☐ Bonus depreciation percentage for your purchase year confirmed
6. ☐ Every deductible category captured in clean books (not a shoebox)
7. ☐ 1099s issued to contractors paid $600+
8. ☐ Entity structure reviewed (how title is held affects everything above)

Where Wyo Stays fits

We can't be your CPA — and we'll never pretend to be. What we can do is run your property so your books are clean, your income and expenses are categorized, and your year-end packet is ready to hand your accountant instead of reconstructing a year from memory. That alone saves most owners real money and a genuinely bad week every April.
