Accelerated Depreciation for Short-Term Rentals: How It Works

By: Adam Jerold Cansino | August 27,  2026

Yes, short-term rental owners may be able to accelerate depreciation on qualifying portions of their property. A cost segregation study can identify assets that may be depreciated over shorter recovery periods than the building itself, while eligible property may also qualify for bonus depreciation.

But there is an important distinction: the size of your depreciation deduction and your ability to use a resulting tax loss are two separate questions. Material participation, passive activity rules, your income, and your broader tax situation can all affect the actual benefit.

Under current federal law, certain qualified property acquired and placed in service after January 19, 2025, is generally eligible for a 100% additional first-year depreciation deduction.

This article discusses general federal tax concepts and is not individualized tax advice. Short-term rental tax treatment depends heavily on the property's facts and the owner.

How Accelerated Depreciation Works on a Short-Term Rental

What Accelerated Depreciation Actually Means

Accelerated depreciation changes when you claim depreciation deductions.

When you purchase a rental property, you generally do not deduct the entire cost of the building in the year you buy it. Instead, the depreciable portion of the investment is recovered over applicable periods under the Modified Accelerated Cost Recovery System, or MACRS.

Accelerated depreciation can move more of those deductions into the earlier years of ownership by identifying property with shorter recovery periods and, when applicable, using bonus depreciation.

That does not mean you have discovered a new expense. In many cases, you are changing the timing of deductions that otherwise would have been recognized over a longer period.

This strategy is also not exclusive to Airbnb or Vrbo properties. Cost segregation and accelerated depreciation are broader tax concepts used with qualifying depreciable property.

How a Short-Term Rental Is Normally Depreciated

Start with the property's depreciable basis.

If you purchase a property for $1 million, that does not necessarily mean you can depreciate $1 million. Land itself is generally not depreciable, so the purchase price typically must be allocated between the land and the depreciable property. Certain acquisition costs and later capital improvements may also affect basis.

For example:

The appropriate recovery period for the building itself depends on how the property is classified for tax purposes. Residential rental property generally uses a 27.5-year GDS recovery period, but the definition excludes certain hotel, motel, inn, or similar transient-use property. Consequently, the appropriate recovery period for an STR should be determined by the facts of the case rather than assuming that all vacation rentals receive identical treatment.

Other assets can follow different schedules. IRS guidance, for example, identifies certain rental furniture, appliances, and carpeting as 5-year property, while some roads, fences, and depreciable landscaping can fall into the 15-year class.

Why the Timing of Depreciation Matters

Why would an investor want more depreciation today instead of later?

A larger current deduction may reduce taxable income sooner, potentially improving current after-tax cash flow. There is also a time-value-of-money consideration: a tax benefit available today may be more valuable than the same nominal benefit received years from now.

But earlier is not automatically better.

Your current taxable income, expected future income, ability to use losses, holding period, future property sales, and overall portfolio strategy can all influence whether accelerating deductions produces a better economic result.

How Cost Segregation Can Accelerate STR Depreciation

Cost segregation is one of the primary tools investors use to accelerate depreciation.

The relationship is straightforward:

Cost segregation identifies and classifies property components → qualifying components receive shorter recovery periods → depreciation deductions may occur sooner.

An STR is not one indivisible depreciable asset. Depending on the facts, it may include the building structure, furnishings, equipment, land improvements, specialty electrical components, decorative elements, and other property that is subject to different tax treatment.

How a Cost Segregation Study Works

A cost segregation study analyzes property costs to determine whether portions of a property or an acquisition can be properly classified separately from the longer-lived building.

The process is more involved than creating a list of furniture.

The IRS Cost Segregation Audit Technique Guide explains that acquired or constructed property may include multiple asset types with different recovery periods, making proper classification important when calculating depreciation.

A detailed study may evaluate construction documents, invoices, plans, property records, physical components, and applicable tax rules to allocate costs among appropriate classifications.

5-, 7-, and 15-Year Property

Why do these classifications matter?

If part of your depreciable basis is properly assigned to 5-, 7-, or 15-year property instead of remaining part of the longer-lived building, you generally recover that portion of the investment faster.

Depending on current law and the characteristics of the asset, some shorter-lived MACRS property may also qualify for bonus depreciation.

There is no universal percentage of an STR that can be shifted into shorter recovery periods. A luxury cabin, beach house, urban condo, and large vacation property with extensive outdoor amenities may produce very different results.

Classification must follow the actual assets and applicable tax rules—not an assumed cost segregation percentage.

Furniture, Appliances, and Interior Assets

Vacation rentals commonly contain substantial personal property, including:

• Beds and mattresses
• Sofas and dining furniture
• Televisions
• Refrigerators and other appliances
• Window treatments
• Décor and furnishings
• Game-room equipment
• Certain electronics and equipment

Some separately acquired assets already have their own depreciable basis. A cost segregation study of a newly purchased building, meanwhile, seeks to identify qualifying components within the broader acquisition.

Those are related concepts, but they are not exactly the same accounting question.

Pools, Hot Tubs, and Outdoor Improvements

STR investors frequently invest heavily in amenities because they can affect nightly rates and guest demand.

Properties may include pools, hot tubs, saunas, fire pits, outdoor kitchens, fencing, landscaping, recreation areas, EV charging equipment, patios, and other exterior improvements.

Do not assume that an asset receives a particular recovery period simply because it appears on a list of common cost segregation items. Tax treatment can depend on the nature of the improvement, its construction, how it is attached to the property, and other facts.

This is one reason a defensible cost segregation analysis focuses on the actual property rather than generic percentages.

Can You Do Cost Segregation on an STR You Already Own?

Potentially, yes.

A property does not necessarily have to be newly purchased for an owner to evaluate cost segregation. In certain circumstances, taxpayers can perform a look-back study and address a change in depreciation treatment by changing their accounting method.

Form 3115, Application for Change in Accounting Method, is used for certain changes involving depreciation methods or recovery periods. A Section 481(a) adjustment can account for differences between depreciation previously claimed and depreciation that should have been allowed under the new method.

This is an area to handle with a tax professional rather than treating Form 3115 as a DIY cost segregation shortcut.

How Bonus Depreciation Can Increase the Upfront Deduction

Cost segregation is not bonus depreciation.

Cost segregation identifies and classifies property. Bonus depreciation is a separate tax provision that may allow eligible property within certain classifications to receive an additional first-year depreciation deduction.

The two strategies often appear together because cost segregation may identify shorter-lived assets that can qualify for bonus depreciation.

Cost Segregation vs. Bonus Depreciation

Think about the sequence:

Cost segregation → identifies property components → components receive appropriate classifications → eligible property may qualify for bonus depreciation.

Current IRS guidance states that certain qualified property acquired and placed in service after January 19, 2025, generally receives a 100% special depreciation allowance unless an applicable election or limitation changes the result. Qualified property may include certain tangible property subject to the MACRS with a recovery period of 20 years or less.

That makes the placed-in-service date and acquisition facts especially important.

Which STR Assets May Qualify?

There is no universal “Airbnb bonus depreciation list.”

Eligibility depends on the asset's tax classification and the requirements of Section 168(k). Certain qualifying shorter-lived personal property or land improvements identified through a cost segregation study may be candidates.

The building itself generally should not be assumed to qualify merely because the property operates as a short-term rental.

Why the Placed-in-Service Year Matters

Buying a vacation rental and placing it in service are not necessarily the same event.

For depreciation purposes, property generally is considered placed in service when it is ready and available for its intended income-producing use. For example, if you close on a property in September but spend several months renovating and furnishing it before it is ready for guests, the purchase date may not be the relevant placed-in-service date.

Because bonus depreciation rules are tied to acquisition and placed-in-service requirements, documenting those dates matters.

What a Larger Upfront Depreciation Deduction Actually Does

A Tax Deduction Is Not the Same as Tax Savings

A $150,000 tax deduction does not equal $150,000 of tax savings.

The financial effect depends on your taxable income, marginal tax rates, other deductions, basis limitations, at-risk rules where applicable, passive activity treatment, and whether the resulting loss can currently be used.

This distinction is especially important in short-term rental discussions because large cost segregation deductions are frequently marketed without explaining what happens to the loss they create.

Example: Accelerated Depreciation on a $1 Million STR

Consider a simplified hypothetical:

Scenario A: No cost segregation

Assume the $800,000 depreciable basis remains primarily in the applicable longer-lived real-property category and is deducted over that property's normal recovery period.

Scenario B: Cost segregation

Assume a professional study determines that $200,000 is properly attributable to qualifying shorter-lived assets. If those assets satisfy the current bonus depreciation requirements, some or all of that $200,000 could potentially be deducted much earlier, while the remaining $600,000 continues to be depreciated under the applicable schedule.

The important result is not that Scenario B magically creates another $200,000 expense.

It changes when depreciation is recognized.

Whether that accelerated deduction produces a useful current tax loss is the next question.

When Accelerating Depreciation May Not Improve the Tax Outcome

A larger current deduction may be less valuable when:

• Current taxable income is already relatively low
• The resulting loss is passive and cannot currently be used
• You expect substantially higher taxable income in future years
• The property may be sold in the near term
• The cost segregation study is expensive relative to the expected benefit
• Personal use limits deductions
• Other tax attributes make additional current deductions less valuable

Good tax planning is not simply about maximizing one year's depreciation.

Why Material Participation Can Change the Value of the Strategy

Generating a loss and being allowed to use that loss against other income are different questions.

This is where many simplified descriptions of the “short-term rental tax loophole” become misleading.

Passive vs. Nonpassive STR Activity

Rental activities are normally subject to specific passive activity rules. However, IRS guidance provides exceptions under which an activity is not treated as a rental activity for these purposes.

One important exception applies when the average customer usage period is 7 days or less. Another applies when average customer use is 30 days or less and significant personal services are provided.

That does not mean every Airbnb is automatically nonpassive.

If the activity falls outside the rental-activity definition under these rules, the owner must still evaluate material participation to determine whether the activity is passive or nonpassive.

The Material Participation Tests

The IRS provides multiple ways an individual can establish material participation.

Examples include participating for more than 500 hours, performing all of the participation in the activity, or satisfying certain other tests based on the owner's involvement.

The correct test depends on the taxpayer's facts.

The 100-Hour Test

The often-discussed “100-hour rule” deserves particular caution.

One material participation test requires the taxpayer to participate for more than 100 hours during the year and at least as much as any other individual involved in the activity.

Simply reaching 100 hours does not automatically turn an STR loss into a deduction against W-2 income.

For example, if a management company or another individual spends considerably more time participating in the activity, that fact may matter when evaluating this particular test.

Does Hiring a Property Manager Affect Material Participation?

Hiring a property manager does not automatically prevent material participation.

It can, however, affect the analysis.

If you are relying on a material participation test that compares your involvement to another person's, the work performed by managers and others becomes relevant. Other material participation tests may operate differently.

Owners should therefore evaluate property management decisions alongside their tax strategy rather than assuming either:

“I hired a manager, so I can never materially participate.”

or

“I made a few important decisions, so I automatically materially participated.”

Neither statement is universally correct.

Documenting Participation

If material participation is important to your tax position, maintain contemporaneous records that can help substantiate your involvement.

Useful records may include:

• Calendars and time logs
• Emails and messages
• Vendor communications
• Guest-related work
• Property visits
• Maintenance coordination
• Pricing and operational decisions
• Bookkeeping or administrative activity that qualifies as participation

Records should reflect work actually performed. Reconstructing inflated or fictitious time logs after the fact is not a legitimate substitute for documentation.

Can Accelerated STR Depreciation Offset W-2 or Other Income?

Potentially—but not simply because you completed a cost segregation study.

A typical analysis looks more like this:

STR activity classification → material participation → depreciation deduction → resulting loss → passive or nonpassive treatment → determines whether and how the loss can currently be used.

When an STR Loss May Be Nonpassive

If the activity is not treated as a rental activity under the applicable passive activity rules and the taxpayer materially participates, the resulting activity may be nonpassive.

That can substantially change the tax economics of accelerated depreciation for certain taxpayers.

But eligibility depends on the actual facts. It should never be assumed based only on the property being listed on Airbnb or having short stays.

When the Loss Remains Passive

Cost segregation can still create or increase a passive loss.

If passive activity rules prevent that loss from being used against nonpassive income in the current year, a large paper deduction may provide far less immediate benefit than expected.

This is why tax modeling should consider not merely how much depreciation a study generates, but also where the resulting loss is reported on the owner's return.

What Happens to Suspended Losses?

Passive losses that cannot currently be deducted may generally be suspended rather than simply disappearing.

They may become applicable to passive income in future years and may also become relevant when the taxpayer disposes of the activity, subject to the applicable rules.

The timing of that future benefit should be incorporated into the cost segregation decision.

Why the “STR Tax Loophole” Is More Than Cost Segregation

“Short-term rental tax loophole” is an informal marketing phrase—not one single provision of the Internal Revenue Code.

What people commonly describe under that label is actually a combination of several separate tax concepts:

Short-term rental classification
→ Material participation
→ Cost segregation
→ Accelerated and potentially bonus depreciation
→ Larger early deduction
→ Rental or business loss
→ Passive or nonpassive treatment
→ Determines how the loss may be used

Ignoring any link in that chain can produce an unrealistic estimate of the strategy's benefit.

What Happens to Accelerated Depreciation When You Sell?

Accelerated depreciation should be evaluated across the property's full investment lifecycle, not just the first tax return after acquisition.

How Depreciation Changes Adjusted Basis

Depreciation generally reduces the property's adjusted tax basis.

The IRS explains that adjusted basis is used to determine gain or loss when property is sold, and depreciation deductions reduce that basis.

Accelerating depreciation today therefore can affect the calculation when you eventually dispose of the property.

What Is Depreciation Recapture?

When depreciated property is sold at a gain, part of the gain may receive special treatment under depreciation recapture rules.

Section 1245 property and Section 1250 property follow different rules. Section 1245 commonly applies to various types of depreciable personal property, while Section 1250 generally covers depreciable real property that is not Section 1245 property.

Because a cost segregation study separates a property into different asset categories, the eventual sale can involve multiple tax classifications.

That does not mean accelerated depreciation is necessarily unattractive. It means the future disposition needs to be modeled alongside the current deduction.

Does Accelerated Depreciation Make Sense If You Plan to Sell?

It depends.

Consider:

• How long you expect to own the property
• The current value of the accelerated deduction
• Expected appreciation
• Potential depreciation recapture
• Future tax rates and income
• Other investments or acquisitions
• Your portfolio strategy

A five-year hold and a twenty-year hold may produce different answers even when the cost segregation study itself is identical.

When Accelerated Depreciation May Make Sense for an STR Investor

Accelerated depreciation may deserve closer analysis when an investor has recently acquired a higher-value property with significant depreciable basis or plans substantial improvements.

It can also be particularly relevant for owners who have high current taxable income, multiple STRs, a longer anticipated holding period, strong participation records, or an ongoing portfolio acquisition strategy.

None of those factors guarantees a favorable result. They simply make the timing and usability of depreciation more important to model.

When Accelerated Depreciation May Not Be the Best Move

Cost segregation is not automatically worthwhile just because it produces a larger first-year deduction.

The strategy may deserve more caution when:

• The property's depreciable basis is relatively small
• You expect to sell soon
• You already have substantial suspended passive losses
• Additional losses cannot currently be used
• The property has significant personal use
• The study cost is high relative to the expected benefit
• Future-year deductions may be more valuable
• Participation records are weak or uncertain

The goal should not be to produce the largest possible depreciation number. It should be to improve the owner's overall tax position.

Think Beyond the First-Year Deduction

The better question is not simply, “How large a deduction can I get from my short-term rental?”

It is:

When should I take the deductions, can I actually use the resulting loss, and how does the strategy affect the property over the full investment period?

Accelerated depreciation should therefore be evaluated alongside current taxable income, expected future income, material participation, existing passive losses, holding period, future acquisitions, planned property sales, and portfolio objectives.

For the right owner and property, cost segregation and accelerated depreciation can meaningfully change the timing of deductions. For someone else, the same study may create suspended losses, shift valuable deductions into future years, or yield less economic benefit than expected.

The objective is not necessarily to maximize depreciation today. It is to determine where depreciation fits within the investor's complete tax and investment strategy.
