When is a new Airbnb placed in service? Why closing by December 31 is not enough

Depreciation on a rental starts when the property is ready and available to rent, not when you close on it. For anyone buying a short-term rental this fall to get a 2026 deduction, that one sentence from IRS Publication 527 decides the year. Close on November 20, spend six weeks furnishing, open the calendar on January 8, and the 2026 return carries no depreciation on that property at all: no building depreciation, no bonus on the furniture, no cost seg year 1. The deduction moves to 2027. The same date also decides whether the painting you paid for in December is a repair or part of what the house cost you.

When is a rental property placed in service?

When it is ready and available for rent. Publication 527 puts it this way: "You place property in service in a rental activity when it is ready and available for a specific use in that activity." Publication 946 uses the same test for every kind of depreciable property.

The IRS gives two examples worth reading closely, because neither one starts at closing and neither one waits for a tenant:

  • A house bought April 6 got extensive repairs, was ready for rent on July 5, was advertised in July and was first rented September 1. It was placed in service in July.
  • An owner moved out in July, made repairs in August and September, listed the house with a rental company on October 1, and got a tenant December 1. It was placed in service October 1.

So the start date sits between the two dates people usually reach for. It is later than closing whenever the place still needs work, beds or a listing. It is earlier than the first booking, because a guest is not required. For an STR, the practical version is the day the property was furnished, legal to rent where it sits, and open on a calendar a guest could actually book.

Do I need a booking before December 31 to depreciate it this year?

No. The test is availability. A property furnished and listed on December 20 with an empty calendar through New Year's is placed in service in December. A property with a December 28 reservation that was still missing beds on December 28 has a harder argument, booking or not.

Available means a guest could have booked it. A listing saved as a draft, or published with every December night blocked, is hard to call available. So is a property waiting on a city short-term rental permit it needs before it can legally take guests. No IRS example covers that last case, so treat the permit's issue date as a fact your CPA will want to see, not as a technicality.

Timeline of a November closing: which costs are capitalized and when depreciation starts, for two ready dates A timeline from November 2026 to January 2027 with a line at December 31. Closing is on November 20. From closing until the property is ready, work such as painting and furnishing is capitalized into the property's cost. In path A the listing goes live on December 10, 2026, so the property is placed in service in 2026 and costs after that date are ordinary rental expenses. In path B the listing goes live on January 8, 2027, so the property is placed in service in 2027 and the 2026 return has no depreciation for it. Same closing, two ready dates The date that matters is the first day a guest could book it Nov 1 Dec 1 Jan 2027 Dec 31, 2026 Closing Nov 20 A capitalize in service: 2026 depreciation, ordinary expenses Listing live Dec 10 B capitalize painting, furnishing, setup work 2027 return Listing live Jan 8 Path B: 2026 depreciation on this property is $0.
Figure 1. Work done between closing and the ready date is part of what the property cost, and the ready date picks the tax year depreciation starts. Sources: IRS Publications 527 and 946; Treas. Reg. §1.263(a)-2(d)(1).

Does closing in December get me 2026 bonus depreciation?

Only if the property, or the piece of it you want to expense, is also placed in service in 2026. Publication 946 says the One Big Beautiful Bill Act "reinstated the 100% special depreciation allowance for certain qualified property acquired and placed in service after January 19, 2025." Both halves count. Buying in 2026 satisfies "acquired." It does not satisfy "placed in service."

Bonus also only reaches property with a recovery period of 20 years or less. The building shell (27.5 or 39 years) never gets it. What gets it is what a cost segregation study moves out of the building: furniture and appliances, some fixtures, land improvements. Publication 527 lists furniture and appliances used in a residential rental as 5-year property. Each of those items has its own placed-in-service date, too. The IRS's own example is a dishwasher bought in November, delivered December 7 and installed January 3. It was placed in service in January.

If you bought under a binding contract signed before January 20, 2025, the 2026 bonus rate is the old phase-down figure (20%), not 100%. The cost seg timing post walks through which rate applies to which purchase.

How much does slipping from December 10 to January 8 move?

Take a hypothetical $400,000 purchase closed November 20, 2026, with the same planning assumptions as our worked loophole example: 80% of the price is building, and a study reclassifies 25% of the building into bonus-eligible classes. That puts $80,000 into 5, 7 and 15-year property and leaves $240,000 of building. The table uses 39 years for the building; the 27.5-year figures are in the paragraph under it.

DeductionA: ready Dec 10, 2026B: ready Jan 8, 2027
2026 bonus on the $80,000$80,000$0
2026 building ($240,000, 39-yr)$257 (0.107%)$0
2026 total$80,257$0
2027 bonus on the $80,000$0$80,000
2027 building$6,154 (full year)$5,906 (2.461%)
2027 total$6,154$85,906
Two-year total$86,411$85,906

The building rows use the mid-month convention in Publication 946's Table A-7a. A December start counts as half of one month, so 0.5 ÷ 12 ÷ 39 = 0.107%. A January start gets 11.5 months, which Table A-7a lists as 2.461%. If your CPA files the building as 27.5-year residential rental property, the December figure is $365 (0.152%) and the January figure is $8,364 (3.485%). Which life applies to an STR is its own question. Section 168(e)(2) says a unit in a hotel or similar establishment where more than half the units are used on a transient basis is not a "dwelling unit," and many preparers put STRs with short average stays on 39 years. Ask before you assume either one.

The two-year totals are almost the same. The miss costs you a year, not the deduction. Whether a year matters depends on what the $80,000 can offset. At a 32% bracket it is worth $25,600 of tax. In path A that lands on the 2026 return. In path B it lands on 2027, against 2027's income, and only if 2027 passes the same participation tests.

2026 and 2027 depreciation for the same $400,000 purchase under two ready dates Bar chart drawn to scale. Path A, ready December 10, 2026: $80,257 in 2026 and $6,154 in 2027. Path B, ready January 8, 2027: $0 in 2026 and $85,906 in 2027. The two-year totals are $86,411 and $85,906. Where the deduction lands Hypothetical $400,000 STR, $80,000 reclassified, 100% bonus, 39-year building A · 2026 $80,257 A · 2027 $6,154 B · 2026 $0 B · 2027 $85,906 Bar length is proportional to dollars (1 px is about $172.50).

Can I deduct the painting and repairs I did before the Airbnb was listed?

Usually not as repairs. Treasury Regulation §1.263(a)-2(d)(1) requires you to capitalize what you pay to acquire property, and says that includes "costs for work performed prior to the date that the unit of property is placed in service by the taxpayer." Example 10 in the same regulation is close to the STR situation: a buyer pays to fix steps, refinish floors, patch walls and paint, all before putting the building in service. None of it is an improvement, and all of it is capitalized anyway, because of when it happened.

That is the part people miss. The same paint job done in February, after the property has been renting since December, can be a deductible repair under the rules in our repairs vs improvements post. Done in December before the listing goes live, it becomes part of the building's basis and is recovered over 27.5 or 39 years. Here is how the usual setup spending sorts out:

CostBefore ready and availableAfter
Purchase price, title, recording, transfer taxesBasis, split between land and buildingn/a
Painting, patching, fixing what was broken at purchaseBasis (capitalized under §1.263(a)-2(d)(1))Often a deductible repair
Furniture, appliances, linens bought to furnish itTheir own 5-year basis, starting when each is in serviceSame, or de minimis if $2,500 or less per item and elected
Utilities, insurance, listing photos, suppliesDepends on the facts (startup cost, basis, or not deductible); ask your CPAOrdinary rental expense
Loan points and feesAmortized over the loan, not added to basisSame

After the ready date, Publication 527 is plain about it: "You can deduct your ordinary and necessary expenses for managing, conserving, or maintaining rental property from the time you make it available for rent." An empty calendar does not change that. A vacant property held out for rent keeps deducting its expenses, depreciation included.

Are pre-listing costs startup costs under §195?

Some can be. Section 195 covers amounts paid to investigate or create an active trade or business that would have been deductible if the business were already running. Think of trips to scout markets, market data subscriptions, and operating costs between closing and opening that are not part of the property's cost. If the rules apply, you deduct up to $5,000 in the year the business begins. That $5,000 shrinks dollar for dollar once startup costs pass $50,000, and whatever is left is spread over 180 months starting the month the business begins.

Two limits keep this smaller than it sounds. First, §195 only reaches costs that would otherwise be deductible, so it never rescues capitalized items like the pre-service painting above. Second, it requires an active trade or business. Whether a particular STR is one is a facts question (stay length, services, how involved you are), and it is the same question the Schedule E vs Schedule C post spends its length on. Your CPA decides which side you are on before any of these costs go anywhere.

What does a December start do to the STR loophole?

It makes the first year short, and a short year is easier to fail. The losses only escape the passive rules if the property's average period of customer use is 7 days or less and you materially participate, and both tests run on the tax year. They do not care that the property only existed for three weeks of it.

The 7-day average is the fragile one. A property placed in service December 10 that books three stays before New Year's (3 nights, 4 nights, and a 16-night holiday family stay) has an average of 23 ÷ 3 = 7.7 days. That is over 7, and the year's loss is passive unless another exception fits. Without the long stay, the average is 3.5. One booking decides the year, and in December the long booking is the likely one. The 14-day rule post covers the other December trap: family nights at the new place count as personal use, not stays.

Material participation is just as tight. Test 1 (500 hours) is hard to reach in three weeks. Test 3 (more than 100 hours and not less than anyone else) compares you with every cleaner and handyman who worked on the property that year. Whether hours you spent setting the place up before it was available count as participation in the rental activity is not something the IRS has answered clearly. Do not build a 2026 loss on them without asking your CPA. The §469 tests post and the hours tracker cover what a log has to show.

What proves the date the property was ready and available?

Dated records made at the time. The IRS examples turn on a ready date and an advertising date, so keep the things that pin those down:

  • The date the listing was published, with a screenshot of the live listing and its open calendar. Keep any platform email confirming the listing was published.
  • Delivery and installation invoices for beds, furniture and appliances, since each item starts its own clock when it is installed.
  • The issue date on any local short-term rental permit or registration the property needs before taking guests.
  • Utility and internet activation dates, plus the smart lock or access code setup date.
  • The first reservation's confirmation, which helps but is not the test.

Write the ready date down for each property and give it to your CPA with the closing statement. It is the date the depreciation schedule starts from, and a preparer who only has the closing date will start there instead.

What to do before December 31 if you are buying now

  1. Work backward from the ready date, not the closing date. Furniture lead times, permit processing and the photographer's schedule are what push a December listing into January.
  2. Get the listing live, with real open nights, once the property is genuinely ready. A published listing with every night blocked does not show availability.
  3. Hold non-urgent cosmetic work until after the ready date if it would be a repair later. Fix what keeps the place from being rentable first.
  4. Decide on a cost seg study now. The study can be done after December 31, but the bonus lands only in the year the reclassified property was placed in service. The timing post covers what happens if you skip year 1.
  5. Watch the December average stay if you are counting on the loophole for 2026, and start the hours log on day one.

The rest of the year-end list (1099s, estimated taxes, the hours log) is in the Q4 tax-season checklist.

Put the ready date where the depreciation math can use it

Try RentReel with a 5-property demo (no signup). Each property has a purchase price, land share, improvements and a placed-in-service month, which the app uses for the mid-month first year and the Schedule E Line 18 estimate, on a 27.5 or 39-year life. If a property is missing its placed-in-service month, the app says Line 18 is zero for it instead of guessing. RentReel does not decide when your property was placed in service or which recovery life applies. Those are your CPA's calls; the app keeps the numbers once they are made.

Frequently asked questions

Is a rental property placed in service on the closing date?

No. A rental is placed in service when it is ready and available for rent, which IRS Publication 527 states as "ready and available for a specific use in that activity." If the property still needs repairs, furniture or a listing after closing, depreciation starts later. In the Publication 527 example, a house bought April 6 and ready for rent July 5 was placed in service in July.

Does an Airbnb need a booking to be placed in service?

No. The test is availability, not occupancy. In the IRS examples a house ready and advertised in July was placed in service in July even though the first tenant arrived September 1. For a short-term rental that usually means furnished, legal to rent, and listed with open nights a guest could book. A draft listing or a fully blocked calendar is weak evidence of availability.

If I close on an Airbnb in December 2026, do I get 2026 bonus depreciation?

Only if the property is also placed in service in 2026. Publication 946 describes the 100% allowance as applying to qualified property acquired and placed in service after January 19, 2025. Closing in December satisfies acquired. If the listing goes live in January 2027, the bonus on furniture and cost seg reclassified property moves to the 2027 return. The building itself never gets bonus.

Can I deduct repairs and painting done before my Airbnb was listed?

Generally not as repairs. Treas. Reg. §1.263(a)-2(d)(1) requires capitalizing costs for work performed before the property is placed in service, and its Example 10 capitalizes painting, patching and floor refinishing done before a building was put in service. Those costs are added to the building's basis and depreciated. The same work done after the property is in service can be a deductible repair.

Are costs before my Airbnb opens deductible as startup costs?

Some can be, under IRC §195, if the rental is an active trade or business and the cost would have been deductible for a running business. Capitalized costs such as pre-service repairs and furniture do not qualify. Up to $5,000 is deductible in the year the business begins, reduced dollar for dollar above $50,000 of startup costs, and the rest is amortized over 180 months. Whether a given STR is an active trade or business depends on its facts.
