Real Airbnb Tax Savings: Three Examples of Owners Who Reduced Their Tax Bills

Many Airbnb owners know they can deduct mortgage interest, property taxes, cleaning fees, utilities, and repairs. What they may not realize is that depreciation can create an even larger tax benefit.

Residential rental property is generally depreciated over 27.5 years. However, certain components of a short-term rental may qualify for much shorter 5-year, 7-year, or 15-year recovery periods.

A cost segregation study identifies and reclassifies those components, potentially allowing the owner to claim a much larger depreciation deduction in the first year.

But how much difference can that actually make?

Here are three simplified examples showing how different Airbnb owners could use cost segregation to reduce their tax bills.

These examples are illustrative and are not representations of guaranteed or actual client results. Calculations are simplified, and the ability to use a deduction depends on the owner’s specific tax situation.

Example 1: The Self-Managed Mountain Cabin

Sarah and her husband purchased a mountain cabin for $450,000 and began operating it as an Airbnb during the year.

After allocating $50,000 to land, which is not depreciable, their depreciable property basis was $400,000.

They handled nearly all aspects of the rental themselves, including:

• Managing the listing

• Communicating with guests

• Setting prices

• Coordinating cleaners

• Purchasing supplies

• Scheduling repairs

• Inspecting the property

• Maintaining the bookkeeping

Their average guest stay was five days, and they documented more than 100 hours of participation. No other individual participated more than either spouse.

Without cost segregation

Without a cost segregation study, the $400,000 building basis would generally be depreciated over 27.5 years.

That would produce approximately $14,545 of depreciation during a full year, before applying the applicable mid-month convention.

With cost segregation

The cost segregation study identified 22% of the depreciable basis, or $88,000, as qualifying shorter-life property.

This included portions of the property related to:

• Appliances

• Certain flooring and finishes

• Decorative lighting

• Cabinets

• Landscaping

• Fencing

• Driveway improvements

• Outdoor entertainment areas

Under current law, eligible property acquired and placed in service after January 19, 2025, may qualify for 100% bonus depreciation. IRS bonus-depreciation guidance

The resulting estimated depreciation looked like this:

	Traditional Depreciation	Cost Segregation
Shorter-life property	$0	$88,000
Remaining building depreciation	$14,545	$11,345
Estimated total	$14,545	$99,345

The cost segregation study accelerated approximately $84,800 of additional depreciation into the first year.

At an assumed 32% federal income tax rate, that could create approximately $27,136 in immediate federal tax savings, assuming the loss was fully deductible.

Why the loss was potentially usable

An activity is generally not treated as a rental activity under the passive-loss rules when the average customer stay is seven days or less. If the owner also materially participates, a resulting loss may be treated as nonpassive. IRS Publication 925

Because Sarah and her husband self-managed the property and maintained records supporting their participation, the loss was potentially available to offset their W-2 income.

This is an important distinction. Cost segregation created the deduction, but material participation helped determine whether the deduction could be used currently.

Example 2: The Professionally Managed Beach House

Michael purchased a beach house for $825,000.

The property was professionally managed because Michael lived several states away.

The management company handled reservations, guest communications, pricing, maintenance, and cleaning.

After allocating $125,000 to land, the property had a depreciable basis of $700,000.

Michael also owned several profitable long-term rentals that generated passive income.

Without cost segregation

Using traditional residential depreciation, the beach house would generate approximately $25,455 of annual depreciation before applying the mid-month convention.

With cost segregation

A cost segregation study identified 24% of the depreciable basis, or $168,000, as property with shorter recovery periods.

The study identified items such as:

• Specialty electrical components

• Certain flooring and finishes

• Built-in decorative elements

• Outdoor lighting

• Landscaping

• Fencing

• Parking and driveway improvements

• Pool-related site improvements

The resulting estimate was:

	Traditional Depreciation	Cost Segregation
Shorter-life property	$0	$168,000
Remaining building depreciation	$25,455	$19,345
Estimated total	$25,455	$187,345

The study accelerated approximately $161,890 of additional depreciation.

At an assumed 35% federal tax rate, the accelerated deduction represented approximately $56,662 in potential federal tax savings.

What if the owner does not materially participate?

Because the management company handled most of the work, Michael did not materially participate in the beach house activity. The loss was therefore passive.

That did not make the cost segregation study worthless.

Michael had passive income from his other rental properties. The beach house loss could potentially offset that passive income, reducing the tax he would otherwise owe.

If Michael did not have passive income, some or all of the loss might be suspended and carried forward. Suspended losses can generally be used against future passive income or may become available when the taxpayer disposes of the entire activity in a qualifying taxable transaction.

This example demonstrates that cost segregation is not limited to owners who self-manage or qualify as real estate professionals. The key is determining when and how the resulting deductions can be used.

Example 3: The Luxury Airbnb Purchased Several Years Ago

Jennifer purchased a luxury vacation rental for $1.4 million in 2023 but did not complete a cost segregation study when she acquired it.

After allocating $200,000 to land, the property had a depreciable basis of $1.2 million.

For several years, Jennifer’s tax returns depreciated the entire building basis over 27.5 years. She later learned that a cost segregation study could potentially be completed even though the property had already appeared on prior tax returns.

The look-back cost segregation study

A look-back study identified approximately $300,000 of the original depreciable basis as qualifying shorter-life property.

Because the property was placed in service in a prior year, the calculation had to apply the depreciation rules and bonus-depreciation percentage that were available when the property was originally acquired and placed in service.

After comparing the depreciation Jennifer had claimed with the depreciation she should have claimed, the study produced an estimated catch-up depreciation adjustment of $218,000.

At an assumed 37% federal tax rate, that deduction represented approximately $80,660 in potential federal tax savings, assuming the adjustment was fully usable.

Was an amended return required?

In many cases, an owner does not need to amend every prior tax return to complete a look-back cost segregation study.

Instead, the taxpayer may be able to file Form 3115, Application for Change in Accounting Method, with the current-year tax return. The missed depreciation is generally reflected through a Section 481(a) adjustment.

The IRS specifically recognizes Form 3115 as the form used to request changes in the accounting treatment of an item, including certain changes involving depreciation. IRS Form 3115 information

The cost segregation study and Form 3115 should be coordinated with the taxpayer’s CPA or tax professional.

Why timing still mattered

Jennifer did not lose the opportunity simply because she had owned the property for several years. However, delaying the study meant she also delayed the tax benefit.

A look-back study can be especially valuable when an owner:

• Purchased property in a prior year

• Did not originally complete a study

• Has significant taxable income in the current year

• Has passive income that can absorb the deduction

• Qualifies as a real estate professional

• Materially participates in a qualifying short-term rental

• Plans to hold the property for several more years

Comparing the Three Examples

	Mountain Cabin	Beach House	Luxury Airbnb
Purchase price	$450,000	$825,000	$1,400,000
Land allocation	$50,000	$125,000	$200,000
Depreciable basis	$400,000	$700,000	$1,200,000
Shorter-life property identified	$88,000	$168,000	$300,000
Accelerated or catch-up deduction	$84,800	$161,890	$218,000
Assumed federal tax rate	32%	35%	37%
Estimated federal tax savings	$27,136	$56,662	$80,660

These estimates do not include state income taxes, potential self-employment taxes, the time value of money, future depreciation reductions, or depreciation recapture upon sale.

Why Every Owner’s Result Is Different

Two properties with the same purchase price can produce very different cost segregation results.

Factors that affect the outcome include:

• Land value

• Property type

• Construction quality

• Renovations

• Landscaping and site improvements

• Pools, patios, and outdoor amenities

• Furniture included in the purchase

• Purchase and placed-in-service dates

• Prior depreciation

• Bonus-depreciation eligibility

• Personal use of the property

• The owner’s tax rate

• Passive versus nonpassive treatment

The amount reclassified is only one part of the analysis. Owners must also determine whether the deduction will actually reduce current taxable income.

Questions to Ask Before Ordering a Study

Before completing a cost segregation study, consider the following:

Does the property have enough depreciable basis?

Land is not depreciable. The expected benefit should be calculated using the building and improvement basis rather than the total purchase price.

When was the property placed in service?

A property is generally placed in service when it is ready and available for rent, not necessarily when it was purchased.

Does the property qualify for bonus depreciation?

The building itself generally does not qualify for bonus depreciation. Certain components classified as 5-year, 7-year, or 15-year property may qualify.

Will the resulting loss be passive?

If the loss is passive, determine whether you have passive income available to absorb it.

Do you materially participate?

For short-term rentals with an average customer stay of seven days or less, material participation can be especially important. Relevant tests include participating for more than 500 hours, performing substantially all the work, or participating for more than 100 hours and at least as much as any other individual.

How long do you plan to own the property?

Cost segregation generally accelerates deductions rather than creating entirely new deductions. Selling the property may create depreciation-recapture consequences, so the anticipated holding period should be considered.

The Bottom Line

Cost segregation can produce meaningful tax savings for many types of Airbnb owners.

A self-managing owner may use the deduction to offset wages or business income if the short-term rental and material participation requirements are satisfied. A passive owner may use the deduction against income from other rental properties. An owner who purchased years ago may still be able to claim missed depreciation through a look-back study and Form 3115.

The most important question is not simply:

“How much depreciation can the study create?”

The better question is:

“How much of the deduction can I use, and when will it provide the greatest tax benefit?”
