Bonus depreciation from an STR can generate a six-figure deduction in year one. But whether that deduction reduces your W-2 taxes — or gets suspended for years — comes down to one question: can you deduct the loss against ordinary income?
The answer depends on Passive Activity Loss (PAL) rules under IRC §469. This article explains the two primary paths STR investors use to qualify, and what each requires in practice.
The Default: Rental Losses Are Passive
Under the general rule, rental income and losses are passive regardless of how much you work. Passive losses can only offset passive income — not W-2 wages, business income, or other non-passive income. If you have no passive income, losses are suspended and carried forward until you have passive income or sell the property.
For most long-term rental investors, this is the rule they live under. Suspended losses accumulate and are released at sale — useful for offsetting gain, but not immediately valuable against ordinary income.
Path 1: The STR Exception (Avg. Stay ≤ 7 Days)
Short-term rentals with an average guest stay of 7 days or less are not treated as rental activities under the PAL regulations. Instead, they are treated as a business activity. That means the PAL rules that classify rentals as passive do not apply by default.
Instead, standard material participation rules apply. If you materially participate in the STR activity, losses flow through as non-passive — deductible against W-2 income and other ordinary income without restriction.
Material Participation Tests (7 IRS Tests — Need to Meet Any One)
- 750-hour test: You participate more than 750 hours during the year in the activity (combined, if applicable)
- 500-hour test: You participate more than 500 hours in the activity
- Substantially all test: Your participation constitutes substantially all of the participation in the activity
- 100-hour / more than others test: You participate more than 100 hours and as much as or more than any other individual
- Significant participation aggregate: Total significant participation activities exceed 500 hours
- Prior 5-year test: You materially participated in any 5 of the prior 10 years
- Personal service activity: The activity is a personal service activity and you participated in any 3 prior years
For STR investors actively managing their property, the 500-hour test or 100-hour test are the most commonly met. Document your hours — contemporaneous logs are important if examined.
Path 2: Real Estate Professional Status
If you qualify as a Real Estate Professional (REP) under §469(c)(7), all rental losses — not just STR — become non-passive. The requirements are strict:
- More than 750 hours per year in real property trades or businesses in which you materially participate
- Those 750+ hours represent more than half of all personal service hours during the year (so if you work 2,000 hours total, at least 1,001 must be in real estate)
In practice, REP status is most accessible when one spouse is a full-time real estate professional (realtor, developer, property manager) and the couple files jointly. A W-2 earner working 40+ hours per week in another field will rarely qualify.
After qualifying as an REP, you must also materially participate in each rental activity (or make a grouping election to treat all properties as one activity). Without material participation, the activity is still treated as passive even for an REP.
Path 3: Passive — What Happens Instead
If you do not meet the STR exception or REP status, your STR losses are passive. They cannot offset W-2 income. However:
- Losses accumulate and carry forward indefinitely
- They offset any passive income you do have (e.g., from other passive investments)
- The full suspended loss is released when you sell the property (in a fully taxable disposition)
- For STR investors with other passive income sources, losses may still be useful
The tax savings shown in this calculator assume you qualify to deduct losses against ordinary income. If you don't qualify, the year-1 savings shown would not apply.
Documentation Is Critical
Material participation and REP status are heavily scrutinized in IRS examinations. Best practices:
- Keep a contemporaneous log (calendar, task management app, email records)
- Document each activity: guest communications, cleaning oversight, maintenance, bookings
- Retain records for at least 7 years
- Work with a CPA experienced in STR and real estate taxation
