About the Author
This guide was written by Matthew Gigantelli, a cost segregation engineer and real estate tax strategist at Overline who has completed engineered studies on over 3,000 properties. Gigantelli holds a B.A. in Finance (summa cum laude) from Rasmussen University and a certification from Boon Tax Educators (2026).
Matthew Gigantelli on STR tax deductions: "I review hundreds of STR tax returns every year. The pattern is always the same: hosts meticulously track their cleaning supplies and toilet paper, then completely miss the deduction that is worth 10x to 50x more than everything else combined. Cost segregation with the STR loophole is not just another line item. It is the strategy that separates hosts who save $3,000 a year from hosts who save $60,000."
The Problem With Every Other "Airbnb Tax Deductions" List
Search for "Airbnb tax write-offs" and you will find dozens of articles listing the same 15-20 deductions: cleaning fees, supplies, insurance, mortgage interest, repairs. They are all correct. They are all incomplete.
Here is why: those deductions typically save an Airbnb host $5,000 to $15,000 per year. Meaningful, but not transformative. The deduction that can save $50,000 to $150,000+ in a single year — accelerated depreciation through cost segregation — is either buried at the bottom of those lists or missing entirely.
This guide covers every legitimate write-off available to Airbnb and short-term rental hosts in 2026. But it is organized by impact, not alphabetically. The deductions that move the needle are at the top.
Tier 1: The Deduction Worth More Than All Others Combined
Accelerated Depreciation via Cost Segregation
Typical annual value: $30,000–$150,000+ (Year 1)
Every rental property depreciates over 27.5 years under standard IRS rules. On a $750,000 property with a $600,000 depreciable basis, that is $21,818 per year in depreciation — a decent deduction, but nothing dramatic.
A cost segregation study reclassifies 20–30% of that depreciable basis into 5-year and 15-year property categories. With 100% bonus depreciation now permanently restored under the One Big Beautiful Bill Act, those reclassified components are deducted entirely in Year 1.
| Property Value | Depreciable Basis (80%) | Cost Seg Reclassified (28%) | Year 1 Bonus Depreciation | Tax Savings (35% bracket) |
|---|---|---|---|---|
| $400K | $320,000 | $89,600 | $89,600 | $31,360 |
| $600K | $480,000 | $134,400 | $134,400 | $47,040 |
| $800K | $640,000 | $179,200 | $179,200 | $62,720 |
| $1M | $800,000 | $224,000 | $224,000 | $78,400 |
| $1.5M | $1,200,000 | $336,000 | $336,000 | $117,600 |
Based on Overline benchmark data from 8,000+ studies. Assumes 80% building-to-land ratio and 28% reclassification rate.
The critical requirement: These losses can only offset your W-2 or active income if you qualify for the STR loophole (average guest stay under 7 days + material participation). Without that qualification, the depreciation is passive and can only offset passive income. With it, a $78,400 deduction directly reduces your salary taxes.
For the complete requirements, see our STR tax loophole requirements guide. For a deep dive on material participation, see our STR material participation playbook.
What it costs: Traditional cost segregation studies run $5,000–$15,000. Overline delivers engineered studies starting at $1k — a 15x to 150x+ return on investment in Year 1 alone.
Tier 2: The Big Recurring Deductions ($2,000–$20,000+/year each)
These are the deductions that show up on every STR tax return. They are significant individually and substantial in aggregate.
Mortgage Interest
Typical annual value: $8,000–$40,000+
All mortgage interest paid on your STR property is deductible against rental income. On a $600,000 loan at 6.5%, that is roughly $38,000 in Year 1 interest alone. This is usually the single largest recurring expense deduction.
If you financed with a DSCR loan, the interest is still fully deductible — DSCR loans are treated identically to conventional mortgages for tax purposes.
Property Taxes
Typical annual value: $2,000–$15,000+
Real estate taxes paid on the STR property are fully deductible against rental income. Unlike your primary residence (which is subject to the $10,000 SALT cap), investment property taxes have no deduction limit.
| State | Effective Rate | Annual Tax on $500K Property |
|---|---|---|
| Tennessee | 0.63% | $3,150 |
| Florida | 0.89% | $4,450 |
| North Carolina | 0.80% | $4,000 |
| Colorado | 0.55% | $2,750 |
| Texas | 1.74% | $8,700 |
Insurance Premiums
Typical annual value: $2,000–$8,000+
Landlord insurance, short-term rental specific policies, umbrella policies, and any additional riders (flood, wind, earthquake) are all deductible. If you are overpaying for insurance, our guide on cost segregation and insurance implications explains how a cost seg study can actually help optimize your coverage.
Property Management Fees
Typical annual value: $3,000–$25,000+
If you use a property manager, their fees (typically 15–25% of gross revenue) are fully deductible. If you self-manage, you cannot deduct a management fee to yourself — but the time you spend managing creates material participation hours that unlock the STR loophole.
Important trade-off: Using a full-service property manager can jeopardize your material participation claim if the manager logs more hours than you on the property. See our analysis of the STR management agreement vs. lease arbitrage tax trap.
Cleaning and Turnover Costs
Typical annual value: $3,000–$15,000+
Professional cleaning between guests, laundry services, and turnover supplies are deductible. For a property running 150+ nights per year with an average stay of 3–4 nights, that is 40–50 turnovers annually.
| Turnover Cost | Per Turn | 45 Turns/Year |
|---|---|---|
| Professional cleaning | $150 | $6,750 |
| Laundry service | $40 | $1,800 |
| Consumable restocking | $25 | $1,125 |
| Total | $215 | $9,675 |
Tax strategy note: If you use a cleaner rotation strategy (switching cleaners periodically so no single cleaner accumulates more hours than you), this also protects your material participation claim. See our grouping election guide for the full rotation strategy.
Repairs and Maintenance
Typical annual value: $2,000–$10,000+
Repairs that maintain the property in its current condition are deductible in the year incurred. This includes plumbing fixes, appliance repairs, HVAC servicing, pest control, and cosmetic touch-ups.
Critical distinction: Repairs are immediately deductible. Improvements (which add value or extend the property's life) must be capitalized and depreciated. The IRS uses the BAR test (Betterment, Adaptation, Restoration) to distinguish between the two. Our repairs vs. improvements guide walks through the exact framework with examples.
Utilities
Typical annual value: $3,000–$8,000+
Electricity, gas, water, sewer, trash, internet, and cable/streaming services are all deductible if the property is used exclusively as a rental. If you use the property personally for part of the year, you must prorate based on rental days vs. personal use days.
Tier 3: Operating Expense Deductions ($500–$5,000/year each)
Platform and Booking Fees
Airbnb charges hosts a 3% service fee on each booking. VRBO charges up to 5%. These fees are deductible as business expenses. On $80,000 in gross bookings, that is $2,400–$4,000 in deductible fees.
Supplies and Consumables
Toiletries, paper products, coffee, kitchen basics, welcome gifts, and any consumables you provide to guests. Track these purchases with a dedicated credit card or accounting category.
Furniture and Furnishings
Furniture, decor, linens, kitchenware, and electronics purchased for the STR. Items under $2,500 can be expensed immediately under the de minimis safe harbor election. Items over $2,500 are depreciated — and if you run a cost segregation study, many of these items fall into 5-year or 7-year MACRS categories and qualify for 100% bonus depreciation.
For renovation-specific deductions, see our STR renovation tax strategy guide.

- Cost segregation study: $1,000–$6,000 (one-time, but deductible)
- Bookkeeping services: $1,200–$3,600/year
Travel to the Property
If your STR is in a different city or state, travel costs to inspect, maintain, or manage the property are deductible. This includes airfare, mileage (67 cents/mile in 2026), lodging (at a hotel, not your own STR), and meals (50% deductible) during property-related trips.
Documentation matters: Keep records showing the business purpose of each trip. A trip that is primarily vacation with a quick property check does not qualify.
Marketing and Photography
Professional photography, drone footage, listing copywriting, social media advertising, and any marketing costs to promote your listing are deductible.
HOA and Condo Fees
Monthly HOA dues, special assessments, and condo association fees are deductible against rental income.
Landscaping and Exterior Maintenance
Lawn care, snow removal, pool maintenance, pressure washing, and exterior upkeep. Landscaping improvements (new plantings, hardscaping) are 15-year property under MACRS and qualify for bonus depreciation through a cost segregation study.
Pest Control
Regular pest treatment and any one-time extermination services.
Security
Security system monitoring, camera subscriptions, and security-related equipment.
Tier 4: Deductions Most Hosts Forget
Startup Costs (Section 195)
If you incurred expenses before your STR was "placed in service" (before the first guest booking), those costs are deductible. Up to $5,000 can be deducted immediately, with the remainder amortized over 15 years. This includes pre-opening renovation, market research, legal setup, and initial furnishing.
Loan Origination Points and Closing Costs
Certain closing costs add to your depreciable basis (transfer taxes, recording fees, title insurance). Others are deductible as business expenses. Our closing disclosure guide walks through every line item.
Home Office Deduction (If You Manage From Home)
If you use a dedicated space in your primary residence exclusively for STR management, you can deduct a proportional share of your home expenses (mortgage interest, utilities, insurance) as a business expense. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 max).
Vehicle Expenses for Local Properties
If your STR is local and you drive to it for management tasks, you can deduct mileage at the IRS standard rate (67 cents/mile in 2026) or actual vehicle expenses. A weekly 20-mile round trip adds up to roughly $700/year.
Partial Asset Disposition
When you replace a component of your property (roof, HVAC, flooring, kitchen), you can write off the remaining undepreciated value of the old component in the year it is removed. This is called partial asset disposition and it is one of the most overlooked deductions in real estate.
Education and Training
Courses, conferences, books, and coaching programs related to STR investing and management are deductible as business education expenses, provided they relate to your existing STR business (not to entering a new field).

The Math That Changes Everything: With vs. Without Cost Segregation
Most Airbnb hosts claim deductions #2 through #26 on the list above. Very few claim #1. Here is what that gap looks like on a real property.
Property: $750K cabin in the Smoky Mountains, purchased January 2026
| Without Cost Seg | With Cost Seg | |
|---|---|---|
| Gross STR revenue | $72,000 | $72,000 |
| Operating expenses (items 3–26) | ($48,000) | ($48,000) |
| Net operating income | $24,000 | $24,000 |
| Standard depreciation | ($21,818) | ($14,727) |
| Accelerated depreciation (cost seg) | $0 | ($168,000) |
| Net taxable income (loss) | $2,182 | ($158,727) |
| Tax owed / (saved) at 35% | $764 owed | ($55,555) saved |
The host without cost segregation owes $764 in taxes. The host with cost segregation receives a $55,555 tax refund that offsets W-2 income. Same property. Same revenue. Same operating expenses. The only difference is a cost segregation study.

How to Maximize Your Deductions: The 2026 Action Plan
Step 1: Get Your Entity Structure Right
Every STR should be in its own LLC for liability protection. The entity structure also affects how losses flow to your personal return. Read our guide on S-Corp vs. LLC for rental property to determine which election makes sense.
Step 2: Track Everything From Day One
Use a dedicated bank account and credit card for each property. Categorize expenses in real time using accounting software. Reconstructing expenses at tax time is how deductions get missed.
Step 3: Run a Cost Segregation Study
This is the single highest-ROI action on this list. Get a free estimate to see your property-specific savings before committing.
Step 4: Qualify for the STR Loophole
Meet the 7-day average stay requirement and document material participation. Without this, your cost segregation losses are passive — still valuable, but they cannot offset W-2 income.
Step 5: Work With a CPA Who Knows STR Tax Strategy
Many CPAs are unfamiliar with the STR loophole and cost segregation integration. Ask your CPA: "How many cost segregation studies have you incorporated into STR returns?" If the answer is zero, find someone who has. Our guide on why your CPA didn't tell you about cost segregation explains the knowledge gap.
Frequently Asked Questions
Q: Do I need to form an LLC to claim these deductions? A: No. You can claim all of these deductions as a sole proprietor filing on Schedule E. However, an LLC provides liability protection that every STR owner should have. See our guide on why entity structure matters.
Q: Can I deduct expenses if my STR loses money? A: Yes. If your STR operates at a loss (expenses exceed income), the loss can offset other income — but only if you meet the STR loophole requirements (7-day average stay + material participation). Otherwise, losses are passive and can only offset passive income.
Q: What if I use my STR personally for part of the year? A: You must prorate deductions based on rental days vs. personal use days. If you rent the property for 200 days and use it personally for 30 days, you can deduct 200/230 (87%) of shared expenses. Days spent on maintenance and repairs count as rental days, not personal use.
Q: Is cost segregation worth it on a property under $500K? A: Often yes. On a $400K property, cost segregation typically generates $25,000–$35,000 in additional Year 1 deductions. At a 35% tax rate, that is $8,750–$12,250 in tax savings — from a study that costs $1,000–$3,000. See our analysis on is cost segregation worth it for the full decision framework.
Q: I bought my STR last year and didn't do cost segregation. Is it too late? A: No. You can do a look-back study on properties purchased in any prior year. The IRS allows you to catch up on missed depreciation in a single year through a Form 3115 change in accounting method — no amended returns needed.
Q: What records do I need to keep? A: Keep receipts for all expenses, bank/credit card statements, mileage logs, booking platform exports, property management agreements, insurance policies, closing documents, and your cost segregation study. The IRS can audit up to 3 years back (6 years if they suspect underreporting), so retain records for at least 7 years.
