Short-Term Rental Cost Segregation

Your STR Property Is Generating a Tax Deduction You've Never Claimed

Cost segregation reclassifies your property's components into 5-year and 15-year asset classes — unlocking 100% bonus depreciation and generating a Year 1 deduction that offsets W-2 income, business profits, and capital gains. Most STR owners have never done this.

The 7-Day Rule — and Why It Changes Everything

IRC §469(c)(7)

The Short-Term Rental Exception

When your property is rented at an average of 7 days or less per booking, the IRS classifies your rental activity differently than standard long-term rentals. Your losses become non-passive — meaning they directly offset your W-2 salary, business income, and capital gains on a dollar-for-dollar basis.

Without this classification, rental losses are passive and can only offset other passive income. Most STR owners on Airbnb or VRBO already meet this threshold without realizing the tax implications.

Combine this with cost segregation's accelerated depreciation and you have one of the most powerful legal tax strategies available to individual investors — generating a large, immediate deduction in the year it matters most.

You likely qualify if:

  • 🏠
    You list on Airbnb, VRBO, or a similar platform
    Most platform-listed properties average under 7 days per booking by default
  • 📅
    Your average booking length is 7 nights or fewer
    Check your platform dashboard — this number is reported in your hosting stats
  • 💼
    You have W-2, business, or capital gains income
    The deduction has to offset something — the higher your income, the more valuable it is
  • 🏡
    Your property was purchased for $250,000 or more
    Cost segregation becomes particularly compelling at higher purchase prices
  • 🛋️
    Your property is furnished
    FF&E — furniture, appliances, and equipment — qualifies as 5-year property and adds significantly to the deduction
The Process

How a Cost Segregation Study Works

A cost segregation study is an engineering-based tax analysis performed by qualified professionals. It identifies and reclassifies building components from their standard 27.5-year depreciation schedule into shorter-lived asset classes that qualify for accelerated and bonus depreciation.

01

Property Analysis

Our team reviews your property records, cost documentation, and improvements. For existing properties, we conduct a thorough retroactive analysis using construction records, purchase agreements, and property inspection data.

02

Component Reclassification

We identify all personal property (5-year), land improvements (15-year), and FF&E components that qualify for accelerated depreciation — separating them from the structural building shell that remains on the 27.5-year schedule.

03

IRS-Compliant Report

You receive a professionally prepared cost segregation report following ASCSP and IRS audit technique guidelines — including a complete depreciation schedule and PDF summary you can share directly with your CPA for implementation.

Estimation Tool

Property Cost Segregation Estimator

Enter your property details to estimate your Year 1 deduction and potential tax savings. Uses IRS-standard component allocation percentages and the correct bonus depreciation rate for your placed-in-service date.

Calculate Your Deduction

Results are estimates. Actual study results vary based on construction type, property age, and improvements.

The One Big Beautiful Bill Act (OBBBA) permanently restored 100% bonus depreciation effective January 19, 2025. Both the acquisition date and placed-in-service date must fall on or after this date to qualify at 100%.

What the Numbers Mean

The Year 1 deduction reduces your taxable income — not dollar for dollar as a credit, but multiplied by your tax rate. At 32%, a $60,000 deduction generates $19,200 in actual tax reduction.

FF&E can add significantly to this figure. A furnished property with $50,000 in qualifying equipment receives bonus depreciation on that amount in addition to the structural analysis.

Tip: Land Value Matters

Land is never depreciable. If your county assessment shows a different land-to-building ratio than the default 20%, enter that number for a more accurate estimate. Check your county property records portal.

The Hidden Multiplier

Furniture, Fixtures & Equipment — What Most Owners Miss

Short-term rental properties carry something most commercial properties don't: a full inventory of furnishings. Every item inside your rental that is tangible personal property — separate from the building structure itself — qualifies as 5-year IRS property class, fully eligible for 100% bonus depreciation.

A well-furnished Airbnb cabin may have $30,000–$80,000 in qualifying FF&E that has never been broken out from the property's standard depreciation schedule. This is one of the most commonly overlooked deductions in real estate.

Your cost segregation study includes a comprehensive FF&E assessment as part of the analysis — we identify, categorize, and value each qualifying item in accordance with IRS guidelines.

Beds, mattresses & bedroom furniture
Sofas, chairs & dining sets
Kitchen appliances
Smart TVs & electronics
Hot tub or outdoor spa
Outdoor furniture & fire pit
Recreational equipment
Washer & dryer

The FF&E Difference — A Realistic Example

A furnished lakehouse purchased for $450,000 with $45,000 in qualifying furnishings, placed in service after January 19, 2025:

Year 1 Deduction Breakdown
Cost seg — 5-yr personal property (100%)$43,200
Cost seg — 15-yr land improvements (100%)$28,800
Structural shell — 27.5-yr straight-line$10,473
FF&E — 5-yr property (100% bonus)+$45,000
Total Year 1 Deduction$127,473
At 32% federal bracket, this generates an estimated $40,791 in tax savings — compared to $13,090 in standard straight-line depreciation. The FF&E alone accounts for $14,400 of that savings.
For Existing Property Owners

Missed It at Purchase? You Can Still Claim It All.

If you purchased your short-term rental property years ago and never performed a cost segregation study, those deductions have not expired — they are waiting for you through a retroactive look-back study filed via IRS Form 3115.

01

Retroactive Cost Segregation Analysis

We perform a full cost segregation study as if it had been conducted at the time of your property's original purchase — reclassifying all qualifying components back to their first year of service.

02

Section 481(a) Cumulative Adjustment

All missed depreciation from prior years is captured in a single Section 481(a) adjustment applied to your current-year tax return. You do not need to amend prior returns.

03

Form 3115 — Automatic Method Change

Your CPA files Form 3115 (Application for Change in Accounting Method) with your current return. Under Revenue Procedure 2015-13, this is an automatic method change — no IRS advance approval required.

04

Current-Year Tax Reduction

Multiple years of accumulated missed depreciation land in a single tax year — frequently eliminating your entire federal tax liability for that year, and in some cases generating a refund.

Look-Back Example — 2022 Purchase

A property purchased in 2022 files a look-back study with the 2025 tax return, capturing all missed depreciation from 2022–2024 in one adjustment:

Purchase price (2022)$550,000
Building value (80%)$440,000
Reclassified property$88,000
Yrs missed (2022–2024)3 years
Catch-up adjustment$97,200
Tax savings (35% bracket)$34,020

Estimates only. Actual results depend on property specifics, land value, FF&E, and applicable bonus depreciation rates by year. Form 3115 is filed by your CPA — we provide the complete documentation package.

Common Questions

Frequently Asked Questions

What exactly is cost segregation, and is it legal?
Cost segregation is an IRS-recognized tax strategy that reclassifies components of a building from 27.5-year (residential) depreciation into shorter-lived asset classes — primarily 5-year personal property and 15-year land improvements. The IRS published its own Cost Segregation Audit Technique Guide in 2004 and has continued to update it, confirming the legitimacy of properly prepared studies. It is used by large real estate investors, institutional owners, and individuals alike.
What is 100% bonus depreciation, and why does it matter?
Bonus depreciation allows you to deduct the full cost of qualifying property in the year it is placed in service, rather than spreading it over its recovery period. The Tax Cuts and Jobs Act of 2017 established 100% bonus depreciation, which then phased down to 80% (2023), 60% (2024), and 40% (Jan 1–18, 2025). The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for property acquired and placed in service on or after January 19, 2025. For cost segregation, this means the 5-year and 15-year components you reclassify can be fully deducted in Year 1 rather than over 5 or 15 years.
I bought my property a few years ago. Is it too late?
No. A Form 3115 look-back study allows you to retroactively apply cost segregation to a property you have owned for any number of years. All missed depreciation from prior years is captured in a single Section 481(a) adjustment applied to your current-year return — you do not need to amend prior returns. This is an automatic accounting method change under Revenue Procedure 2015-13, meaning no IRS advance approval is required. Your CPA files Form 3115 with your current return and the catch-up deduction is applied that year.
Does this trigger an IRS audit?
A properly prepared cost segregation study, following IRS audit technique guidelines and ASCSP methodology, is a well-documented and defensible tax position. The IRS has recognized cost segregation as a legitimate strategy since the Hospital Corporation of America tax court case in 1997. Studies that are prepared with engineering-level documentation, proper asset class citations, and complete component schedules are routinely accepted without issue. Studies purchased from discount providers that use blanket percentage allocations without property-specific analysis carry substantially more risk.
What happens when I sell the property — depreciation recapture?
Depreciation recapture is a real consideration. When you sell the property, the IRS recaptures accelerated depreciation on personal property and land improvements at ordinary income tax rates (up to 25% for real property under Section 1250). This does not eliminate the strategy's value — the benefit is deferral and arbitrage. You receive the deduction today at your current marginal rate, and recapture occurs later, potentially at a lower rate or offset by a 1031 exchange. Many owners plan for this with their CPA in advance. We discuss recapture implications as part of your property analysis.
How much does a cost segregation study cost?
Study fees vary based on property size, complexity, purchase price, and whether a look-back is involved. Because every property is different — different construction type, different FF&E inventory, different land basis, different property age — we do not publish standard pricing. Your free analysis call will include a specific fee proposal based on your property. What we can say is that for properties purchased at $300,000 or more, the study cost is typically recovered many times over in the first year's tax savings alone.
Do I need to use a specific CPA, or can I work with my existing accountant?
You keep your existing CPA. We prepare the cost segregation report and all supporting documentation — including the Form 3115 package for look-backs — in a format designed for direct handoff to your accountant. We will coordinate directly with your CPA to answer any questions about the study's methodology and implementation. You do not need to change any of your existing tax relationships.
Bonus Depreciation Timeline

100% Bonus Depreciation Is Back — But Policy Can Change

The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for property acquired and placed in service on or after January 19, 2025. The phase-down years that preceded it illustrate how quickly this can change. Every year you delay is a year you don't capture the full benefit.
