Cost Segregation for Airbnb and Short-Term Rentals

If you own an Airbnb, VRBO, or another short-term rental, cost segregation may accelerate depreciation by identifying assets with shorter recovery periods. Whether it produces a current benefit depends on the property's basis and components, bonus-depreciation eligibility, the owner's ability to use the loss, state rules, fees, holding period, and sale consequences.

A cost segregation study identifies individual components and assigns supportable recovery periods. Current federal law generally restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, but the result is not automatic. Material participation is only one of several loss-usability gates, and projected deductions should not be presented as guaranteed tax savings.

This guide covers everything you need to know about cost segregation for Airbnb and short-term rental properties: how it works, what components qualify, how much you can save, and how to implement it whether you just bought your property or have owned it for years.

The four questions an STR owner must keep separate

The seven-day average-customer-use rule is part of the passive-activity regulations. It does not automatically assign a 39-year building life. Section 168 separately asks whether at least 80% of gross rental income is from dwelling units and whether a unit is in a hotel, motel, or other establishment where more than half the units are used on a transient basis. Apply the actual property and operating facts before selecting 27.5 or 39 years.

Which components may have shorter recovery periods?

A defensible study classifies an asset by its function, permanence, attachment, design, and relationship to the building—not by a generic STR percentage. The analysis commonly considers:

Bonus depreciation is an eligibility test

Current federal law generally allows 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. A study does not make every short-life asset bonus-eligible. Acquisition date, placed-in-service date, class life, eligible used-property rules, related-party status, business-use percentage, ADS requirements, elections, and state conformity can change the result. Properties acquired before that date can fall under different percentages and transition rules.

Worked decision example: deduction is not the same as tax savings

Assume an owner buys and places in service a furnished STR for $900,000. A supported land allocation is $180,000, leaving $720,000 of depreciable basis. A property-specific study supports $185,000 of five-, seven-, and fifteen-year basis. If that entire amount separately qualifies for current federal bonus depreciation, $185,000 is the accelerated deduction before remaining building depreciation—not $185,000 of cash-tax savings.

If the owner's basis and at-risk amounts are sufficient but the owner does not materially participate, the loss may be passive and suspended. If the owner materially participates and the activity is nonpassive, the deduction may offset other nonpassive income, subject to excess-business-loss and other return-level rules. State treatment can produce another schedule entirely. The proposal should model these results rather than multiplying purchase price by a fixed percentage and tax rate.

Five gates before treating the projected loss as usable

1. Tax basis: verify depreciable building basis and prevent duplicated acquisition or improvement costs.
2. At risk: determine which cash, debt, and guarantees create an amount at risk.
3. Activity classification: apply average-customer-use and significant-service rules to the actual operating model.
4. Material participation: test the owner's credible, supportable participation—not merely ownership or self-management.
5. Return-level limits: model passive carryovers, excess-business-loss rules, state nonconformity, and any other applicable limitations.

New property, one prior return, or an adopted method?

• Placed in service on the current return: classify assets and establish the correct schedules from the start.
• One prior return: determine whether the current procedure permits a method change for one-year property or whether a current-year correction, amended return, partnership AAR, or another route applies.
• Two or more returns using an impermissible method: a method may have been adopted. A qualifying automatic Form 3115 change can use a Section 481(a) adjustment, but scope limitations, designated change number, timing, attachments, and duplicate-copy procedure must be checked.

Use the detailed Form 3115 cost-segregation guide for the filing map. Property age alone never proves that Form 3115 is available or that an amendment is prohibited.

Documents to gather before ordering the study

• Closing statement, purchase agreement, appraisal, and land-allocation support
• Placed-in-service evidence, booking history, average-stay data, and personal-use records
• Prior returns, depreciation schedules, fixed-asset ledger, and passive-loss carryovers
• Construction, renovation, furniture, appliance, and site-improvement invoices
• Plans, surveys, photographs, property-condition reports, and insurance schedules
• Ownership documents, debt records, state filing footprint, participation logs, and expected sale or conversion date

Common failure points

• Using the purchase price instead of depreciable basis after removing land and duplicated personal-property costs
• Assuming every STR is automatically 39-year property because guests average seven days or less
• Assigning cabinets, hardwood flooring, plumbing fixtures, or lighting to short lives without function and attachment analysis
• Applying one reclassification percentage to every property type and fact pattern
• Treating bonus eligibility, deduction size, loss usability, and cash-tax savings as the same number
• Filing Form 3115 merely because the property is older without establishing an adopted method and the correct procedure
• Ignoring state depreciation adjustments, sale-year recapture, suspended losses, or a near-term conversion to personal use

What should the proposal include?

AE's published study price is $1 per square foot with a $2,000 minimum. Compare providers on the total delivered scope: inspection method, asset-level schedules, basis reconciliation, legal support, source-cost documentation, report revisions, depreciation exports, Form 3115 work, federal and state return implementation, and examination support. Those items are not interchangeable, and work outside the study should be scoped separately.

A quality report should identify its approach and preparer, reconcile allocated costs to total depreciable basis, document estimates and adjustments, support asset classifications, and address related accounting-method issues. The IRS Audit Techniques Guide describes six study approaches; it does not require one branded method for every property.

What Is Cost Segregation and Why Does It Matter for STR Owners?

Cost segregation is an engineering-based tax strategy that breaks down a real property asset into its individual components and assigns each component to the correct depreciation category under the Internal Revenue Code. Instead of treating your entire property as a single asset depreciating over 39 years, a cost segregation study identifies which parts of the property qualify for accelerated depreciation over 5, 7, or 15 years.

Think about what your Airbnb actually consists of. It is not just four walls and a roof. It is furniture, appliances, light fixtures, plumbing fixtures, flooring, cabinetry, landscaping, a driveway, a patio, decorative finishes, and dozens of other components. Each of these has a different useful life under IRS rules, and each one can be depreciated on its own schedule.

For short-term rental owners specifically, cost segregation matters more than almost any other real estate strategy because of three converging factors:

• Building recovery period: The structural remainder may be 27.5- or 39-year property. The Section 168 dwelling-unit and transient-establishment facts decide; the seven-day passive-activity rule does not.
• Bonus depreciation: Current federal law generally provides 100% bonus for qualifying property acquired and placed in service after January 19, 2025. Each asset still must satisfy the eligibility rules, and state treatment can differ.
• Loss usability: When an STR activity is not treated as a rental activity and the owner materially participates, losses may be nonpassive. Basis, at-risk, excess-business-loss, and other limits still apply.

Without a property-specific comparison, an owner cannot know whether the timing benefit exceeds the cost and later recapture. The decision should be modeled, not assumed.

Why STRs Are Classified Differently: The 39-Year Recovery Period

One of the most important (and most misunderstood) aspects of short-term rental tax treatment is the property classification under the Internal Revenue Code. This classification is what makes the entire STR tax strategy possible, and it is worth understanding thoroughly.

Under IRC Sec. 168(e)(2), residential rental property generally has a 27.5-year recovery period when at least 80% of gross rental income is rental income from dwelling units. A unit in a hotel, motel, or other establishment is excluded from the dwelling-unit definition when more than half of the units are used on a transient basis. The statute does not use a 30-day average-stay test for this classification.

Some short-term rentals are 39-year nonresidential real property, but a seven-day average stay does not create that result automatically. The seven-day rule belongs to the Section 469 passive-activity regulations; the Section 168 dwelling-unit and transient-establishment facts determine the building recovery period.

A 39-year recovery period generally slows depreciation on the structural remainder, but it does not itself make the activity nonpassive. Activity classification and material participation require a separate Section 469 analysis.

This distinction is critical. For a deeper comparison of how STRs and LTRs are treated differently under the tax code, see our guide to STR vs LTR tax treatment.

When your STR is classified as a nonresidential, non-passive activity (because you materially participate), the paper losses generated by cost segregation are not trapped as passive losses. They can offset your ordinary income. That is the entire foundation of the STR tax loophole, and cost segregation is what creates the large losses that make it worthwhile.

Component Breakdown: What Gets Reclassified in a Furnished STR

A cost segregation study examines every component of your property and determines the correct depreciation life under IRS guidelines. For a furnished short-term rental, the reclassification opportunities are extensive because STRs typically contain far more personal property (furniture, appliances, decor) than a standard rental.

Here is how the major categories break down:

5-Year Property (MACRS)

The largest category for most STR properties. These are components that the IRS considers personal property or property with a useful life that justifies a 5-year recovery period:

• Furniture: Beds, dressers, nightstands, sofas, dining tables, chairs, desks, bookshelves, TV stands, outdoor furniture, and all other furnishings. In a fully furnished Airbnb, this alone can represent 10-15% of property value.
• Appliances: Refrigerator, dishwasher, washer, dryer, microwave, stove/oven, garbage disposal, and small appliances. These are almost always classified as 5-year personal property.
• Cabinetry: Kitchen cabinets, bathroom vanities, built-in shelving, and closet systems. Many property owners do not realize that cabinetry can be separated from the building structure.
• Carpet and vinyl flooring: Carpet, vinyl, and other non-permanent floor coverings are classified as 5-year property because they have a shorter useful life and are not permanently affixed to the building.
• Plumbing fixtures: Sinks, faucets, toilets, bathtubs, shower fixtures, and related plumbing accessories. The plumbing system itself (pipes in the walls) remains structural, but the fixtures attached to it are separable.
• Lighting fixtures: Chandeliers, pendant lights, recessed lighting trim, wall sconces, under-cabinet lighting, and decorative lighting. The electrical wiring is structural, but the fixtures are personal property.
• Decorative finishes: Backsplash tile, accent walls, wainscoting, crown molding used for decorative purposes, and specialized wall treatments. These are distinguished from structural finishes by their decorative function.
• Window treatments: Blinds, shutters, curtains, curtain rods, and decorative window films.
• Electronics and entertainment: TVs, sound systems, smart home devices, security cameras, and related electronics.

7-Year Property (MACRS)

A smaller but still significant category:

• Hardwood flooring: Unlike carpet, hardwood floors have a longer useful life and are typically classified as 7-year property.
• Specialized equipment: Hot tubs, saunas, game room equipment, and other specialized amenities common in vacation rental properties.

15-Year Property (MACRS)

Land improvements and site work that qualify for a 15-year recovery period:

• Landscaping: Trees, shrubs, sod, irrigation systems, retaining walls, and garden features. For properties with significant outdoor appeal (lake houses, mountain cabins, beachfront properties), landscaping can be a substantial component.
• Site improvements: Driveways, parking areas, patios, decks, sidewalks, fencing, gates, outdoor lighting, and retaining walls.
• Utility connections: The portions of water, sewer, gas, and electrical connections that extend from the building to the property line.

The supportable shorter-life percentage varies materially by property design, renovations, documentation, and asset mix. A study should start with depreciable basis after land and then classify each component. Current 100% bonus depreciation applies only to qualifying property that satisfies the acquisition, service-date, use, election, and other eligibility rules.

Typical Tax Savings by Property Value

The following scenarios are illustrations, not forecasts. They show why a fixed 35% reclassification and tax-rate assumption should be replaced with property-specific basis, classification, bonus, loss-usability, state, fee, holding-period, and sale modeling:

$200,000 Property

• Depreciable basis (excluding land): approximately $170,000
• Amount reclassified and accelerated into Year 1: approximately $70,000
• Estimated Year 1 tax savings: $25,000+
• Without cost segregation, Year 1 depreciation would be approximately $4,359 (straight-line over 39 years)

$400,000 Property

• Depreciable basis (excluding land): approximately $340,000
• Amount reclassified and accelerated into Year 1: approximately $140,000
• Estimated Year 1 tax savings: $50,000+
• Without cost segregation, Year 1 depreciation would be approximately $8,718

$600,000 Property

• Depreciable basis (excluding land): approximately $510,000
• Amount reclassified and accelerated into Year 1: approximately $210,000
• Estimated Year 1 tax savings: $75,000+
• Without cost segregation, Year 1 depreciation would be approximately $13,077

$1,000,000 Property

• Depreciable basis (excluding land): approximately $850,000
• Amount reclassified and accelerated into Year 1: approximately $350,000
• Estimated Year 1 tax savings: $125,000+
• Without cost segregation, Year 1 depreciation would be approximately $21,795

These numbers illustrate the dramatic difference between standard depreciation and cost segregation. On a $400,000 property, you would normally deduct about $8,718 in Year 1. With cost segregation and bonus depreciation, you can deduct approximately $140,000 in Year 1. That is a 16x increase in your first-year depreciation deduction.

Bonus Depreciation Under OBBBA: 100% Permanent, No Phasedown

The tax landscape for cost segregation changed dramatically with the passage of the One Big Beautiful Bill Act (OBBBA). Under the original Tax Cuts and Jobs Act (TCJA) of 2017, 100% bonus depreciation was available through 2022, after which it was scheduled to phase down: 80% in 2023, 60% in 2024, 40% in 2025, 20% in 2026, and 0% in 2027.

OBBBA eliminated this phasedown entirely. 100% bonus depreciation is now permanent under the law. There is no sunset, no phasedown, and no expiration date.

For STR owners, the restored federal percentage is only the first step. Each asset must be eligible, and acquisition date, placed-in-service date, eligible used-property rules, related-party status, business use, ADS, elections, and state conformity can require a different result.

This permanent status also removes the urgency-driven decision-making that characterized the phasedown years. You no longer need to rush a cost segregation study before a deadline. The benefit is available whenever you are ready to claim it. That said, every year you delay is a year of tax savings you are forfeiting, so there is still a strong incentive to act promptly.

For property placed in service in a prior year, a Form 3115 catch-up may be available after an impermissible method has been adopted and the current procedure is satisfied. A current-year correction, amended return, partnership AAR, or another path may apply instead.

Material Participation: The Key to Using STR Losses Against W-2 Income

Cost segregation generates the paper losses. Material participation is what unlocks the ability to use those losses against your W-2 income, business income, and other active income sources.

Under IRC Sec. 469, passive activity losses can generally only offset passive income. For long-term rental properties, losses are almost always classified as passive (with a limited exception for active participants earning under $150,000). This is why most LTR owners cannot use their depreciation losses to offset their salary.

Short-term rentals are different. Because STR properties with average rental periods of 7 days or less are not treated as "rental activities" under the IRC Sec. 469 regulations (specifically Treas. Reg. 1.469-1T(e)(3)(ii)(A)), they are instead treated as trade or business activities. This means the passive activity loss rules apply based on whether you materially participate, not based on a blanket classification as rental.

If you materially participate in your STR, the activity is non-passive. If it is non-passive, the losses (including the massive accelerated depreciation from cost segregation) can offset your W-2 income. This is the STR tax loophole in action.

To materially participate, you must meet at least one of the seven IRS tests. The most commonly used tests for STR owners include:

• Test 1: You participate in the activity for more than 500 hours during the tax year.
• Test 3: You participate for more than 100 hours during the tax year, and your participation is not less than any other individual's participation.
• Test 4: The activity is a significant participation activity (more than 100 hours), and your total participation in all significant participation activities exceeds 500 hours.

For many Airbnb hosts who actively manage their properties (handling bookings, guest communication, cleaning coordination, maintenance, pricing, and restocking), meeting the 500-hour or 100-hour tests is very achievable. Detailed time logs and documentation are essential for substantiating material participation in the event of an IRS inquiry.

Form 3115: Claiming Missed Depreciation on Existing Properties

One of the most common questions we hear from STR owners is: "I have owned my property for several years and never did a cost segregation study. Is it too late?"

It may not be too late, but the filing path depends on the returns already filed and the method adopted. Form 3115 (Application for Change in Accounting Method) can permit a Section 481(a) catch-up when the taxpayer, property, method, and current procedure qualify.

Here is how it works. When you perform a cost segregation study on an existing property, the study identifies which components should have been depreciated on accelerated schedules from the date the property was placed in service. The difference between the depreciation you actually claimed (using straight-line over 39 years) and the depreciation you should have claimed (using accelerated schedules) is called the Section 481(a) adjustment.

This adjustment is taken as a single deduction in the current tax year. You do not need to go back and amend prior-year tax returns. The entire cumulative catch-up amount flows through as a deduction on your current return.

For example, if you purchased a $400,000 STR five years ago and have been depreciating it straight-line over 39 years, you have claimed approximately $43,590 in total depreciation over those five years. Had you performed a cost segregation study at the time of purchase, you would have claimed approximately $140,000 in Year 1 alone (with bonus depreciation), plus continuing depreciation on the remaining components. The Section 481(a) adjustment captures the difference, which can easily exceed $100,000 in additional deductions.

A qualifying catch-up can be material, but it is not automatic and filing errors can create exposure. Learn more in the detailed guide on Form 3115 for cost segregation catch-up.

The Cost Segregation Process: Step by Step

Understanding the process from start to finish helps you know exactly what to expect when you engage AE Tax Advisors for a cost segregation study. Here is how it works:

Step 1: Initial Engagement and Property Information

The process begins with a discovery consultation where we assess your property, your tax situation, and whether cost segregation is the right strategy for you. We gather basic property information including the purchase price, closing statement (HUD-1 or settlement statement), property address, year built, any renovations or improvements, and current use as a short-term rental.

Step 2: Property Analysis and Site Review

Our engineering team conducts a thorough analysis of your property. For many STR studies, this includes a detailed review of property records, photographs, blueprints or floor plans (when available), and county assessor data. The goal is to create a comprehensive inventory of every component of the property.

Step 3: Component Identification and Classification

This is the core of the cost segregation study. Every component is identified and classified into the appropriate MACRS depreciation category: 5-year personal property, 7-year property, 15-year land improvements, or 39-year structural/building components. The classification follows the IRS Cost Segregation Audit Techniques Guide and applicable court precedents.

Step 4: Engineering-Based Cost Allocation

Costs are allocated to identified components using the study's disclosed methodology, source data, estimates, and adjustments. The IRS Audit Techniques Guide describes six approaches and quality attributes; the report should explain its chosen approach and reconcile all allocated costs to depreciable basis rather than relying on an unsupported rule of thumb.

Step 5: Report Delivery

You receive a comprehensive cost segregation report that includes a detailed listing of every reclassified component, the cost allocated to each, the depreciation category assigned, and the resulting depreciation schedules. This report serves as your documentation in the event of an IRS audit and integrates directly with your tax return preparation.

Step 6: Tax Return Integration

The study must be implemented on the correct return and schedule. New property can generally be classified on its placed-in-service return; prior-year property requires analysis of whether Form 3115, an amended return, a partnership AAR, or another correction procedure applies. Confirm implementation scope in the engagement.

The entire process typically takes 2 to 4 weeks from engagement to final report delivery.

AE Tax Advisors Pricing and Engagement Structure

Transparency in pricing is important to us. Here is how our engagement structure works for STR owners:

• Cost Segregation Study: $1/sq ft ($2,000 minimum). The proposal should state the property-analysis, component-identification, cost-allocation, revision, and report deliverables. Form 3115, return implementation, state work, and examination support must be confirmed in the engagement scope rather than assumed.
• Advisory Engagement: $7,800 per year. This is your comprehensive tax strategy engagement that includes full short-term rental tax strategy development, material participation documentation guidance, tax return integration, and ongoing advisory support throughout the year.
• Prior-Year Amendments: $2,500/year. If we identify opportunities to amend prior-year returns (beyond the Form 3115 catch-up, which is included), amendment work is billed at $2,500 per tax year amended.

A 2,000-square-foot property would meet the published $2,000 study minimum, but its return on investment must be calculated from the usable federal and state tax benefit, implementation costs, holding period, and sale effects—not from square footage alone. Visit our pricing page for the current service breakdown.

The Full Picture: Cost Segregation and STR Tax Deductions

Cost segregation is the centerpiece of STR tax optimization, but it works alongside a broader set of Airbnb tax deductions that every short-term rental owner should be claiming. These include operating expenses like property management fees, cleaning costs, supplies, insurance, property taxes, mortgage interest, utilities, maintenance and repairs, marketing costs, and professional fees.

When cost segregation is combined with these standard deductions and the losses are activated through material participation, many STR owners find that their Airbnb generates a significant tax loss on paper, even while producing positive cash flow. This is not a contradiction. It is the intended result of a well-structured tax strategy.

A paper loss may offset W-2 or other nonpassive income only when the activity is nonpassive and the owner clears basis, at-risk, excess-business-loss, and other applicable limits. Otherwise the loss may be suspended. For a broader deduction overview, visit Airbnb tax deductions.

Why AE Tax Advisors Is the Right Choice for Your Cost Segregation Study

Not all cost segregation studies are created equal, and not all tax advisors understand the specific nuances of short-term rental tax strategy. Here is what sets AE Tax Advisors apart:

Engineering-Based Methodology

We use a property-specific approach informed by the quality attributes in the IRS Cost Segregation Audit Techniques Guide. The report should identify components, explain classifications and estimating methods, reconcile allocated costs to depreciable basis, and cite relevant authority. No methodology guarantees an examination outcome.

IRS-Compliant, Audit-Ready Reports

Reports are prepared to document the component list, cost-allocation methodology, source data, assumptions, and authority supporting each classification. If examined, the taxpayer must still substantiate basis, placed-in-service facts, asset treatment, and return implementation.

STR-Specific Expertise

Short-term-rental tax strategy is not the same as general real estate tax planning. Average customer use, the separate 27.5-versus-39-year building-life analysis, material participation, Section 469, and the interaction with cost segregation require coordinated review. AE Tax Advisors works with STR owners nationwide, and this is a core area of our practice.

Nationwide Service

We serve short-term rental owners in all 50 states. Whether your Airbnb is in the Smoky Mountains, Scottsdale, the Florida Keys, Lake Tahoe, or anywhere in between, we can perform a cost segregation study and develop a comprehensive tax strategy for your property.

Full-Service Tax Advisory

Our cost segregation studies start at $1 per square foot with a $2,000 minimum. Advisory, material participation, Form 3115, return integration, state work, and ongoing support should be confirmed in the specific engagement scope. We can coordinate with an existing CPA so study assumptions and return treatment are reviewed together.

Real-World Impact: How the Numbers Come Together

To illustrate the full impact of cost segregation for an STR owner, consider this scenario:

An investor purchases a $500,000 furnished Airbnb in a popular vacation market. The investor has a W-2 job earning $250,000 per year and actively manages the Airbnb, meeting the material participation tests under IRC Sec. 469.

For illustration, assume the facts support a 39-year structural life and approximately $425,000 of depreciable building basis after land and separately purchased furnishings. Straight-line building depreciation would be roughly $10,900 per year before the applicable convention. Whether an operating loss is nonpassive and usable requires the activity, participation, basis, at-risk, and return-level tests described above.

Continue the illustration by assuming a property-specific study supports $175,000 of shorter-life basis and every included asset separately qualifies for current federal bonus depreciation. That can produce a large federal deduction, but state conformity, elections, business use, and return-level limits can change the deductible or usable amount.

If the owner materially participates, has sufficient basis and amount at risk, clears the excess-business-loss and other limits, and the state conforms, some or all of the loss may offset W-2 income. A 37% rate applied to a fully usable $150,000 deduction would equal $55,500 of modeled current tax reduction; that is an assumption-driven illustration, not a promised result.

And here is the part many investors overlook: the cash flow from the Airbnb is still positive. The depreciation is a paper deduction, not a cash expense. The investor is collecting rent, covering expenses, and generating positive cash flow while simultaneously reducing their W-2 tax bill by $55,000. That is the power of cost segregation combined with the STR strategy.

Common Misconceptions About Cost Segregation

There are several misconceptions that prevent STR owners from pursuing cost segregation. Let us address the most common ones:

"My Property Is Not Expensive Enough"

Cost segregation can work at different price points, but a $200,000 property is not automatically economic. Compare depreciable basis, supportable reclassification, usable tax benefit, state treatment, study and implementation fees, holding period, and sale effects before proceeding.

"It Will Trigger an Audit"

The IRS publishes a Cost Segregation Audit Techniques Guide explaining how examiners evaluate studies. A study does not prevent an audit or guarantee a classification; it should document basis, methodology, estimates, asset facts, legal support, and return implementation.

"I Will Have to Pay It All Back When I Sell"

When you sell the property, you will owe depreciation recapture tax under IRC Sec. 1250 (taxed at a maximum rate of 25%). However, the time value of money makes this a favorable trade. You are receiving a large tax deduction today at your marginal rate (which may be 35-37%) and paying it back at a lower rate (25% maximum) at some future date. Additionally, strategies like 1031 exchanges can defer the recapture indefinitely.

"I Have Owned My Property for Years, So I Missed the Boat"

As discussed above, Form 3115 may permit a Section 481(a) adjustment after a qualifying method change. Statutes, disposition, ownership changes, method history, scope limitations, and current procedures can affect whether relief remains available.

"My CPA Said It Is Too Aggressive"

Many general-practice CPAs are unfamiliar with cost segregation because it falls outside their typical scope of work. Cost segregation is not aggressive. It is explicitly supported by the Internal Revenue Code, Treasury Regulations, and the IRS's own published guidance. If your CPA is unfamiliar with it, that is understandable, but it should not prevent you from pursuing a legitimate, well-documented strategy.

Getting Started: Your Next Steps

If you own an Airbnb or short-term rental and have not evaluated cost segregation, a return-level review can determine whether the timing benefit is supportable and economic. Some properties benefit materially; others should wait or decline.

Here is how to get started with AE Tax Advisors:

1. Schedule a discovery call. Request a free consultation to discuss your property, your tax situation, and whether cost segregation is the right fit. There is no obligation and no pressure.
2. Provide basic property information. We will need your purchase price, closing statement, property address, and a general description of the property and its furnishings.
3. We conduct the study. Our team handles the entire cost segregation process from analysis through report delivery, typically in 2 to 4 weeks.
4. Integrate with your tax return. We work with you (or your existing CPA) to ensure the results are properly reflected on your tax return, capturing every dollar of available savings.

Timing matters, but speed should not replace eligibility and return review. Model the study before filing, refinancing, converting use, or selling so the deduction, state adjustments, and exit consequences are coordinated.
