Can I Take Bonus Depreciation on a December Airbnb? (2026)

Every December, the same question lands in every STR-focused CPA inbox: "I just closed on my Airbnb — can I still take bonus depreciation this year?" The answer is almost always yes, but the reason is subtle. The IRS does not care about closing date or first booked guest. It cares whether the property was in a condition or state of readiness and availability for its intended rental use by the last day of your tax year.

This is the "placed in service" test, and it's the single most misunderstood concept in short-term rental tax planning. Get it right and you unlock a five- or six-figure Year 1 deduction. Get it wrong and you defer the entire deduction to next year. If you already missed the deadline in a prior year, there is a fix: the catch-up election for past years recovers missed bonus depreciation on property you already own.

What "Placed in Service" Actually Means (IRS Standard)

The controlling rule is Treas. Reg. §1.167(a)-11(e)(1)(i), which defines placed-in-service as the time property is "first placed in a condition or state of readiness and availability for a specifically assigned function." The same standard is echoed in Treas. Reg. §1.46-3(d)(1)(ii).

Translated for a short-term rental: your Airbnb is placed in service the moment it is genuinely ready and genuinely available to accept guests. Both words matter.

• Ready — physically capable of hosting a paying guest. Furniture in, utilities on, safety items in place, cleaning done.
• Available — offered for its intended use. Listing live on Airbnb, VRBO, or your booking platform, calendar open for reservations.

This is why the question of when an Airbnb becomes placed in service for depreciation so often gets muddled. Investors conflate three different dates: closing (title transfer), placed-in-service (readiness + availability), and first booking (actual use). Only the middle one triggers bonus depreciation under §168(k).

The December 31 Deadline: What You Actually Need Done

For a December placed-in-service date to hold up, you need a defensible file showing the property was ready and available before the year turned. Here is the practical checklist that most experienced STR CPAs work from:

• Live listing on a booking platform. Airbnb, VRBO, or Booking.com listing published, publicly visible, and accepting reservations.
• Fully furnished. Beds, seating, kitchenware, linens, TVs, and any advertised amenities in place. A property advertised as sleeping eight cannot be placed in service with three mattresses on the floor.
• Utilities active. Electric, gas, water, internet, and any advertised services on in the operating entity's name.
• Safety compliance. Smoke detectors, CO detectors, fire extinguishers, and any state or local STR safety requirements installed.
• Required permits. STR permit, transient occupancy tax registration, HOA approvals, business license — all issued and on file.
• Insurance in force. STR or commercial liability policy bound with an effective date on or before placed-in-service. A landlord policy alone usually is not sufficient.
• Cleaning and inspection complete. Post-turnover cleaning, keyless entry setup, welcome guide done.

You do not need every one of these to be week-old to qualify. But you do need the file to show that as of December 31, a guest could have walked in the door and stayed the night. That is the standard.

First Booking Is Not Required (Common Misconception)

This is where most investors — and a fair number of generalist CPAs — get tripped up. The myth is that an Airbnb needs a paying guest by December 31 to be placed in service. It does not. The question is not "was it rented?" — the question is "could it have been rented?"

The IRS position applies across property types. A rental with a live listing and an empty calendar is placed in service. A hotel with the lights on and the desk staffed but no guests that night is placed in service.

So does an Airbnb need to be rented by December 31 for depreciation? No. If a guest could have hit "book" and shown up on New Year's Eve, the property is placed in service — even if nobody did. A property that closes on December 22 and goes live on December 27 is placed in service in that tax year, even if the first booking is not until February.

What Doesn't Count as Placed in Service

The mirror image matters just as much. Common scenarios where investors think they meet the December 31 deadline but do not:

• Closed for renovation. A property mid-remodel is not in a state of readiness. Renovation and placed-in-service are mutually exclusive.
• Awaiting furniture. If the listing advertises "furnished" and the furniture has not arrived, placed-in-service is when the furniture is in and the property could host guests.
• No live listing. A furnished, permitted, insured property with utilities on but no listing is not available. Readiness alone doesn't carry the day.
• Awaiting certificate of occupancy or STR permit. If your municipality requires a permit or CO to legally operate an STR, the property is not available until the permit issues. Pending is not enough.
• Personal use only. A second home you and your family are using in late December with no listing and no rental intent is not placed in service as a rental.

The pattern: if the property could not have been booked and occupied by a paying guest on December 31, it was not placed in service. Bonus depreciation moves to the following tax year.

Evidence to Keep for Your CPA

Placed-in-service matters most when it is close to the year boundary. A June date rarely gets scrutinized. A December 28 date needs a file. Build the file at the time — not two years later.

A defensible placed-in-service file for a December Airbnb:

• Listing screenshot with publish date. Airbnb and most platforms surface the date a listing was first activated. Capture the listing page and the host dashboard "listing created" date.
• Booking calendar screenshot. Dated screenshot showing the calendar was open in the final days of December.
• Permit issuance dates. STR permit, business license, or transient occupancy tax registration with issue date.
• Insurance policy effective date. Declarations page of the STR or commercial liability policy showing coverage started on or before your placed-in-service date.
• Utility activation records. First bill or activation email from each utility in the operating entity's name.
• Dated interior photos. Photos of the finished, furnished interior — ideally with EXIF metadata intact. Also useful for the line-item deduction analysis your CPA or cost seg firm will do.
• First inspection or cleaning invoice. Service record from your cleaner, property manager, or inspector before year-end.
• Any owner blocks or reservation activity. Even without a booked guest, screenshot owner blocks or reservation requests from the final week.

Your CPA needs enough evidence to walk an examiner through the timeline: closing, readiness, listing, availability — with dates on every step.

How the Deduction Actually Sizes Up in Year 1

Placed-in-service is the gate. Once you pass it, the Year 1 deduction depends on the property's bonus-eligible mix — the split between 5-year personal property (finishes, appliances, FF&E), 15-year land improvements (pools, hot tubs, outdoor kitchens, landscaping), and 39-year structural. Only 5-year and 15-year qualify for bonus depreciation under §168(k).

For a typical short-term rental, 5-year and 15-year property together run 15–28% of purchase price, depending on furnishings, outdoor amenities, and your property's land allocation. On a $750,000 Airbnb, that's a Year 1 deduction of $112,000–$210,000.

100% bonus depreciation applies to qualifying property acquired and placed in service after January 19, 2025 (OBBBA). If your December closing falls after that date, you are in the current 100% regime.

To turn the deduction into cash tax savings you also need to clear the passive-activity hurdle — for most STR owners, the STR loophole (average guest stay of seven days or less) plus material participation for the STR loophole (typically the 100-hour "most active participant" test). Placed-in-service unlocks the deduction; material participation determines whether it can offset W-2 income.

What Happens If You Miss December 31

If the property was not placed in service by December 31 — furniture arrived in January, permit issued in February, listing not live until spring — the bonus depreciation deduction moves to the following tax year. Not the end of the world, but a full-year deferral, which is meaningful if you were counting on it to offset current-year income.

Two situations to know:

• Deferred to the next tax year. If a December closing did not place in service in time, the Year 1 deduction attaches to the actual placed-in-service date next year. Not lost — shifted.
• Missed in a prior year and never claimed. If you own an STR placed in service in a prior year and never claimed bonus depreciation, you can recover it with an IRS Form 3115 filing and a §481(a) catch-up adjustment on a current-year return. No amended returns, no statute-of-limitations cutoff — full missed deduction in one filing.

Frequently Asked Questions

Can I take bonus depreciation if I bought my Airbnb in December?

Yes — if the property was placed in service (available and ready for rent) by December 31. A December 20 closing with a live listing on December 28 qualifies. A December closing that sits empty into January does not.

When does an Airbnb become placed in service for depreciation?

When the property is in a condition or state of readiness and availability for its intended rental use — the standard from Treas. Reg. §1.167(a)-11(e)(1)(i). In practice: furnished, utilities on, safety compliance done, permits issued, insurance bound, listing live and accepting bookings.

Does an Airbnb need to be rented by December 31 for depreciation?

No. The IRS test is availability and readiness, not actual use. A live listing with an open calendar meets the standard even if no guest books in the final days of the year.

What if my Airbnb was closed for renovation on December 31?

It is not placed in service. Mid-renovation, awaiting furniture, waiting on a CO, or without a live listing all fail the readiness test. The placed-in-service clock starts the day the property is genuinely available for its intended use.

What evidence do I need to prove the placed-in-service date?

Listing screenshot with publish date, permit issuance, insurance effective date, utility activation records, dated interior photos, first cleaning invoice, and any calendar activity from the final days of December.

What happens if I miss the December 31 placed-in-service deadline?

Year 1 bonus depreciation defers to the next tax year. If you missed it in a prior year and never claimed bonus depreciation, IRS Form 3115 with a §481(a) catch-up recovers the entire missed deduction on a current-year return — no amended returns required.

Does the closing date count as placed-in-service?

No. Closing is title transfer. Placed in service is availability + readiness for rental use. For a turnkey furnished STR with an active listing at closing, the two dates can coincide. Otherwise, placed-in-service is later.

Is 100% bonus depreciation still available for a December placed-in-service property?

Yes. 100% bonus depreciation applies to qualifying property acquired and placed in service after January 19, 2025 (OBBBA). Eligible 5-year personal property and 15-year land improvements are 100% deductible in Year 1.
