When Can You Claim Bonus Depreciation on a Short-Term Rental? The Placed-in-Service Rules (2026)

The Rule That Controls Everything: “Placed in Service”

Under IRS rules, depreciation, including bonus depreciation, begins when property is placed in service. Not when you buy it, not when you pay for improvements, and not when your first guest checks in.

The IRS definition: property is placed in service when it is ready and available for its specific use. For a rental property, that means ready and available to rent. IRS Publication 946 uses a rental example that maps directly onto STRs: a house is placed in service the month repairs are finished and it’s advertised for rent, even though no tenant has moved in yet.

For a short-term rental, “ready and available” in practice looks like:

• Renovations and furnishing are complete, and the property could host a guest tonight
• Required licenses or permits are in place (and a certificate of occupancy, if applicable)
• The listing is live and bookable on Airbnb, VRBO, or your direct booking site, or the property is otherwise being actively marketed for rent

Note what’s not on that list: a completed booking. Your first guest stay does not set the placed-in-service date. A property listed and bookable on December 20 is in service on December 20, even if the first reservation isn’t until January.

The flip side is equally important. A property you’ve bought but are still renovating is not in service, no matter how much you’ve spent on it. Money out the door doesn’t start the depreciation clock. Readiness does.

The $250,000 Renovation Question: Spend Year vs. In-Service Year

Here’s the scenario that trips up hosts: you spend $250,000 this year buying and renovating a property, but it doesn’t go live until next year. Do you lose the deduction on this year’s spend?

No, but you don’t get it this year, either.

When you spend money getting a rental ready before it’s placed in service, those costs aren’t deducted in the year you spend them. They’re capitalized, added to the property’s depreciable basis, and they sit there waiting. The moment the property is placed in service, the entire accumulated basis becomes depreciable, and the qualifying personal property components (furniture, appliances, fixtures, landscaping: the things a cost segregation study identifies) become eligible for bonus depreciation in the placed-in-service year.

So in the $250,000 example:

• Spend $250,000 in 2026, property goes live in March 2027: You claim nothing on the 2026 return for that property. In 2027, the full $250,000 (allocated between structure, land, and personal property) enters the depreciation system, and the qualifying components get 100% bonus depreciation on your 2027 return.
• Spend $250,000 in 2026, property goes live in December 2026: Same total deduction, but it lands on your 2026 return instead.

The deduction is deferred, not lost. What you’re really choosing with your timing is which tax year absorbs the paper loss. And that choice matters enormously if you have a specific high-income year you’re trying to offset. If 2026 is the year with the big W-2 bonus or business exit you want to shelter, a property that slips into service in January 2027 does nothing for your 2026 bill.

Why December 31 Matters, and Why December 28 Is Risky

Because placed-in-service is a tax-year question and the U.S. individual tax year runs January through December, December 31 is the line. In service by December 31: this year’s deduction. January 2: next year’s.

Here’s a detail that surprises many hosts: bonus depreciation is not prorated for a late-year start. A qualifying asset placed in service on December 20 gets the same 100% first-year bonus deduction as one placed in service on January 5. (The remaining 27.5-year structure depreciation is prorated, since residential real property uses a mid-month convention, but the bonus portion, which is where the big first-year number comes from, is all-or-nothing by year.)

That makes a December scramble sound like free money. It isn’t, because bonus depreciation is only half of the STR strategy. The other half is what makes the loss usable against your W-2 or business income, and both of those tests are measured within the same tax year:

• Material participation. You need to satisfy a material participation test (commonly 100+ hours with no one participating more than you, or 500+ hours) for the year. If the property enters service on December 28, you have four days of operational activity to point to. Some hours spent preparing the property may count toward the activity, but this is exactly the kind of gray area where documentation and CPA guidance matter.
• The 7-day average stay test. The STR exception to passive-loss treatment depends on the average guest stay being 7 days or less. A property with zero completed stays by December 31 gives you very little to demonstrate that average with.

The practical takeaway: a late-December in-service date can absolutely secure a full-year bonus deduction, and hosts do it every year, but the later in the year you go live, the thinner your support for the material participation and average-stay tests becomes, and the more the losses risk being classified as passive (usable only against passive income, not your salary). If your loss ends up passive, it isn’t gone, since passive losses carry forward, but the headline benefit of the STR strategy is deferred until you can use it.

If a year-end deadline is driving your timeline, plan backwards from December: furnishing done in October, listing live in early November, real bookings and logged hours on the books before the year closes. Early November in service beats December 28 in service every time, at zero cost to the deduction amount.

The Two Clocks: Acquisition Date vs. Placed-in-Service Date

Since the One Big Beautiful Bill Act, there are two dates that matter, and they answer different questions:

• The placed-in-service date decides which tax year you claim the deduction.
• The acquisition date decides which bonus depreciation rate you get.

Under the OBBBA, 100% bonus depreciation applies to qualifying property acquired and placed in service after January 19, 2025. Property acquired before January 20, 2025 remains under the old TCJA phase-out rates (40% for property placed in service during 2025, for example) even if it goes into service later.

For most hosts reading this in 2026, both clocks land safely on the right side of the line: buy in 2026, place in service in 2026 or 2027, and the qualifying components get the full 100% rate in whichever year service begins. The two-clock distinction mainly matters if you acquired a property in 2024 or early January 2025 that’s only now going live. In that case, talk to your CPA before assuming the 100% rate applies. (Self-built or heavily self-renovated properties have their own acquisition-timing wrinkles; that’s a CPA conversation, not a blog-post rule of thumb.)

Three Timing Scenarios, Walked Through

Scenario 1: Buy, renovate, and list in the same year.
You close in March 2026, spend $80,000 furnishing and renovating through the spring, and your listing goes live June 1, 2026. The property, purchase price plus capitalized improvement costs, is placed in service June 1. A cost segregation study identifies the short-life components, and 100% bonus depreciation on those components lands on your 2026 return. You have seven months to log material participation hours and build a guest-stay history. This is the clean version.

Scenario 2: Spend this year, go live next year.
You close in September 2026 and start a major renovation that runs through February 2027. The listing goes live March 2027. Every dollar spent in 2026 is capitalized, and nothing is deductible on your 2026 return for this property. In 2027, the full basis enters service and the bonus deduction hits your 2027 return. If you were counting on this property to offset 2026 income, this timeline fails silently: you find out at tax time.

Scenario 3: The December sprint.
You close in October 2026 and push to get furnished, permitted, and listed by December 15. The full bonus deduction is available on your 2026 return, with no proration. But you have sixteen days to support material participation and an average-stay history. Doable with aggressive documentation and ideally some completed stays, but this is the highest-audit-risk version of the strategy. If you’re here, log everything and get your CPA involved before December, not in April.

Documenting Your Placed-in-Service Date

Because so much rides on one date, evidence matters. If the IRS ever asks when your property was ready and available for rent, you want a paper trail, not a recollection:

• Screenshot of your listing going live, with the date visible
• Your platform’s listing activation email or dashboard record
• Certificate of occupancy or final inspection sign-off, if applicable
• STR license or permit issue date
• Dated photos of the furnished, guest-ready property
• Contractor completion certificates and final invoices
• First dates the booking calendar was open for reservations

Five minutes of screenshots in November can protect a six-figure deduction. This is also the natural moment to run your numbers: our bonus depreciation calculator for short-term rentals will show you what the first-year deduction looks like for your purchase price and cost segregation estimate, and therefore what’s at stake in getting the year right.

Common Timing Mistakes

1. Assuming the deduction follows the spend. It follows the in-service date. Renovation dollars spent in a year the property isn’t yet live produce no deduction that year.
2. Waiting for the first booking to “count” the property as in service. Ready and listed is in service. If you were bookable on December 20, don’t push your in-service date to January just because your first guest arrived then. You may be deferring a deduction you already earned.
3. Going live December 28 and expecting the full STR loophole. The bonus deduction survives a late start; the material participation and 7-day-average support often doesn’t. The deduction may land, but as a passive loss you can’t use against W-2 income this year.
4. Forgetting the property has to stay qualified. Placed-in-service gets you into the system, but the 7-day average stay and material participation are tested for the year. A December launch followed by a 30-day January booking can wreck the average before you’ve started.
5. Not telling your CPA the timeline until tax season. Timing strategy only works prospectively. By the time you’re filing, the in-service date is history. Loop your CPA in while the calendar can still be moved.

Frequently Asked Questions

The Bottom Line

Bonus depreciation timing comes down to one rule with two edges. The forgiving edge: money spent early isn’t wasted. It’s capitalized and deducted, in full, the year your property goes live, with no proration for a late-year start. The strict edge: the deduction lands in the in-service year whether that’s the year you wanted or not, and the tests that make the loss usable against your active income are measured in that same year.

If you’re acquiring a property with a specific tax year in mind, work backwards from December 31, and leave yourself more runway than the bonus rules technically require, because the STR loophole tests need real operating history, not just a live listing.

Three things to do right now:

1. Map your in-service date against the tax year you’re trying to offset, and confirm the math with our free bonus depreciation calculator
2. If you’re targeting this year, get the listing live by early November, not late December
3. Start the documentation folder now: listing screenshots, permits, dated photos, participation log
