Short-Term Rental Tax Deductions in 2026: The Complete Guide to What Hosts Can Write Off

Here is something most people figuring out their first STR tax return do not expect to hear: the tax treatment for a well-structured short-term rental is genuinely good. Not “minimize the damage” good. Actually good. Mortgage interest, depreciation, repairs, platform fees, cleaning costs, utilities, all deductible. Layer in bonus depreciation for furniture and equipment, and the after-tax return on a well-run STR can look 20 to 30 percent better than the gross income number suggests.

The IRS is not doing you any favors here, exactly. But the code is structured to allow real deductions that make STR investing more attractive than the headline numbers show. At a 24% marginal rate, every $10,000 in legitimate deductions is $2,400 that stays in your pocket. Scaled across mortgage interest, depreciation, and the platform fees that quietly add up over a full year, you start to understand why experienced STR investors talk about after-tax cash flow rather than gross receipts.

This guide covers the full deduction landscape for 2026, with specific IRS publication and section references throughout. You should involve a CPA if your situation involves material participation elections or real estate professional status. But you should also walk into that conversation knowing what you own.

Schedule E or Schedule C: Getting the Form Right First

The most consequential tax decision for most STR hosts is one they never get asked directly: which form are you on? Get it wrong and everything downstream gets complicated in ways that are hard to unwind.

The default answer, the correct answer for the overwhelming majority of Airbnb and VRBO hosts, is Schedule E. IRS Publication 527 (Residential Rental Property) establishes Schedule E (Form 1040) as the standard reporting form for rental income and expenses. That is where standard STR income belongs.

Schedule C applies only when you provide substantial services to guests during their stay. The IRS definition of substantial services, per Publication 527 and Topic 415, refers to hotel-like services: daily cleaning during occupancy, preparing meals, or providing ongoing entertainment for guests. The keyword here is “during.” Cleaning the unit between bookings, which every STR host does, is not a substantial service. Sending someone to clean the room each morning while guests are in residence is.

Physical goods provided to guests, sports equipment rentals, attraction tickets, gift baskets, do not count as substantial services because they are not services. They are goods. (Yes, the IRS draws this distinction in writing, and yes, it matters.)

Why the form matters: Schedule C income is subject to self-employment tax of 15.3% on net profit, on top of ordinary income tax. Schedule E is not. For most hosts, Schedule E means a lower overall tax bill on the same rental income.

One important nuance: under IRC Section 469, STRs with an average guest stay of 7 days or fewer are not classified as “rental activities” for passive activity purposes. They are treated as active business activities. This means losses are not subject to the passive activity loss limitations that otherwise cap how much rental loss you can use against ordinary income, provided you materially participate. More on that in the material participation section.

The Operating Expense Deductions

Once you are properly on Schedule E, the list of deductible operating expenses under IRS Publication 527, Chapter 2 is substantial. Here is how each major category works in practice.

Mortgage Interest

If you financed your STR, every dollar of mortgage interest paid is deductible as a rental expense under IRC Section 163. For a host using a DSCR loan, which is the standard financing vehicle for most STR investors today, this deduction alone can represent tens of thousands of dollars per year. On a $400,000 balance at 7%, year-one interest approaches $28,000. All of it deductible.

Property Insurance

Insurance premiums are fully deductible under IRS Publication 527. This includes your standard homeowners policy, any STR-specific coverage endorsements, and liability insurance. The full annual premium is deductible in the year paid.

Repairs and Maintenance

Repairs, meaning work that restores the property to its prior condition without adding material value, are deductible in the year the expense is incurred. Painting a room, replacing a broken appliance, fixing a leaky faucet: repairs, all of them deductible now. The line that matters under the IRS tangible property regulations (Revenue Procedure 2015-82) is between a repair and an improvement. Improvements must be capitalized and depreciated over time. Servicing your HVAC unit is a repair. Replacing it entirely is an improvement.

Utilities

Electricity, water, gas, internet, and cable are fully deductible when paid by the host. Whether you build utilities into your nightly rate or absorb them as a host-covered cost, what you actually pay is deductible under IRS Publication 527.

Platform Fees

Airbnb, VRBO, and Booking.com charge host fees on each transaction. These fees, whether the 3% host-only fee or a higher split-fee structure, are fully deductible as ordinary and necessary business expenses under IRC Section 162. If you generate $60,000 in gross bookings and pay $1,800 in platform fees, the $1,800 comes straight off your rental income before calculating tax.

Cleaning and Turnover Costs

Housekeeping services, turnover management platforms, and individual cleaner payments are all deductible. The cleaning fees your guests pay show as income; what you actually spend on cleaning shows as an offsetting deduction. These two numbers are rarely the same, which means you likely have a real expense here.

Supplies

Guest supplies, toiletries, paper products, coffee, laundry detergent, replacement linens and towels, kitchen items, are deductible as purchased. This adds up over a full year of turnovers. Keep receipts, or at minimum keep a running total from your purchasing history.

Property Management Fees

If you use a professional property manager, their management fee (typically 20 to 30 percent of gross revenue) is deductible as a rental expense under IRS Publication 527.

Legal and Professional Fees

CPA fees, legal fees related to your rental business, and costs for professional services used in managing your STR are deductible ordinary business expenses under IRC Section 212. This includes the accountant you hire to prepare your Schedule E and the attorney you retain to review your rental agreement.

Depreciation: Where the Real Leverage Lives

Depreciation is the deduction most first-time STR investors underestimate. It is also the one that most dramatically changes the after-tax return calculation, because it costs nothing out of pocket while reducing taxable income year after year.

The 27.5-Year Residential Depreciation Schedule

Under IRS MACRS (Modified Accelerated Cost Recovery System, detailed in IRS Publication 946), residential rental property depreciates over 27.5 years. This is the baseline for your STR investment.

Here is how it works in practice: if you purchase a property for $350,000 and allocate $50,000 to land (land does not depreciate), your depreciable basis is $300,000. Divided over 27.5 years using the mid-month convention, you receive a depreciation deduction of approximately $10,909 per year. That deduction costs you nothing. Over a 10-year hold, that is roughly $109,000 in depreciation deductions. At a 24% marginal rate, that translates to approximately $26,000 in cumulative tax savings.

A cost segregation study, performed by an engineering firm or CPA specializing in real estate, reclassifies components of the building that qualify as personal property or land improvements. Flooring, cabinetry, certain plumbing and electrical fixtures, and landscaping often shift from the 27.5-year bucket into 5-year or 7-year MACRS categories. For a $350,000 property, a cost segregation study might identify $50,000 to $80,000 in reclassifiable assets, accelerating the depreciation timeline significantly.

100% Bonus Depreciation Under the OBBBA

For STR properties acquired after January 19, 2025, the One Big Beautiful Bill Act (signed July 4, 2025) permanently restored 100% bonus depreciation for qualifying property under IRC Section 168(k). This is the most significant recent change to the depreciation landscape for real estate investors, and it applies directly to STR furnishings and improvements.

Under 100% bonus depreciation, furniture, appliances, qualified improvements, and other personal property placed in service after January 19, 2025 can be fully expensed in year one rather than spread over 5 to 7 years. A 2-bedroom STR typically requires $8,000 to $20,000 in furnishings. At the $14,000 midpoint, full expensing in year one at a 24% marginal rate returns $3,360 immediately. For investors setting up multiple properties in a single tax year, this compounds quickly.

For a full analysis of OBBBA mechanics, cost segregation interaction, and how to structure bonus depreciation within your overall tax plan, dedicated coverage is coming in next week’s piece specifically on what the One Big Beautiful Bill changed for STR investors.

Section 179 Expensing

Under IRC Section 179, qualifying tangible personal property can be immediately expensed rather than depreciated on a schedule. For tax year 2026, the Section 179 deduction cap is $2,560,000 (phase-out begins above $4,090,000 of total qualifying property placed in service). For any individual STR operator, this cap is effectively unlimited relative to typical furnishing and equipment budgets.

Section 179 is a useful tool for property acquired before January 19, 2025 that does not qualify for OBBBA 100% bonus depreciation, or as a complement to bonus depreciation on a year-by-year basis. Your CPA can advise on which approach produces the better outcome for your specific tax situation.

The 14-Day Personal Use Rule

This is the rule that costs hosts deductions when they do not read it carefully. Understanding it precisely matters, because the threshold is lower than most people assume.

IRS Publication 527 and Topic 415 define the vacation home threshold:

• If you use the property personally for more than 14 days or more than 10% of the total days you rented it at fair market rate (whichever is greater), the IRS classifies it as a vacation home.
• Under vacation home classification, expenses must be proportionally allocated between rental use and personal use, and you cannot deduct a rental loss against other income.

Picture this: You own a mountain cabin you rent through Airbnb for 150 days per year and use personally for 20 days. Twenty days exceeds the 14-day threshold. The IRS proportionally allocates your expenses: 150 divided by 170 total use days means approximately 88% of eligible expenses are deductible as rental costs. The remaining 12% is a nondeductible personal expense. You also cannot use a rental loss to offset your W-2 or other income.

Same cabin, but you limit personal use to 10 days. You are under both thresholds: 10 days is below the 14-day cap, and 10 days is below 10% of 150 rental days (which would be 15 days). The property is treated as a pure rental under IRS Publication 527. Full deductibility, and rental losses can potentially offset other income subject to the passive activity rules discussed below.

One clarification that matters: days you spend at the property doing repairs and maintenance work do not count as personal use days per IRS Publication 527. If you spend a weekend repainting or fixing the deck, those days do not log against your personal use count. Keep records showing the nature of the work done on those days.

Commonly Missed Deductions

Standard operating costs get covered in most tax guides. These tend to fall through the cracks.

Vehicle Mileage

Every trip to your STR for a rental-related purpose is deductible. Trips to check on the property, meet a repair contractor, deliver supplies, or address a guest issue all qualify. The IRS standard mileage rate for 2026 is 72.5 cents per mile (per IRS Notice 2026-10, up 2.5 cents from 2025). Keep a contemporaneous mileage log showing date, destination, business purpose, and miles driven. Vehicle mileage is a category that draws IRS scrutiny; documentation here is not optional.

Home Office Deduction

If you manage your STR operation from a space in your home used regularly and exclusively for business, a portion of your home expenses is deductible under IRC Section 280A. The simplified method allows $5 per square foot up to 300 square feet, for a maximum deduction of $1,500. Hosts who self-manage bookings, guest communication, and financials from a dedicated home workspace should not leave this one on the table.

Professional Development

Books, online courses, and conference registrations directly related to your STR business are deductible as ordinary and necessary business expenses under IRC Section 162. STR data subscriptions used for investment analysis qualify on the same basis.

Loan Origination Fees

Points and origination fees paid on your DSCR loan at closing are deductible, generally amortized over the life of the loan rather than deducted fully in year one. This amount appears on your closing disclosure and does not show up on monthly statements, which is exactly why it gets overlooked at tax time. Pull your closing disclosure and check what you paid.

State and Local Occupancy Taxes

Many states and localities impose lodging taxes, occupancy taxes, or transient accommodation taxes on short-term rental revenue. The taxes you remit are deductible as business expenses. This is separate from real property taxes on the property itself, which are also deductible under IRS Publication 527.

HOA Fees

Homeowners association fees paid on your STR property are deductible as rental expenses for the rental-use period. If personal use days are a factor, proportional allocation applies.

When to Bring In a CPA: Material Participation and REPS

Everything covered above is primarily mechanical. You had the expense, you document it, you deduct it. This section is where the difference between a general tax preparer and a CPA who specializes in real estate investment genuinely matters.

Material Participation and the Short-Term Rental Exception

Under the passive activity loss rules of IRC Section 469, rental losses are generally passive. Passive losses can only offset passive income. If your STR shows a loss but you have no passive income to absorb it, the loss is suspended until you sell the property or generate passive income elsewhere.

Here is the exception that matters for most STR investors: short-term rentals with average guest stays of 7 days or fewer are not classified as rental activities under IRC Section 469(c)(2). They are treated as active business activities. If you materially participate in the operation, losses can offset ordinary income including your W-2 salary, without running into the passive activity limitation.

Material participation requires meeting one of seven tests under Treasury Regulation 1.469-5T. The most accessible for working STR hosts are: more than 500 hours in the activity during the year, or more than 100 hours with no other individual spending more time on it than you. Keep a time log throughout the year. A reconstructed log assembled in April is both less reliable and less defensible than a contemporaneous one.

Real Estate Professional Status

For STRs with average stays longer than 7 days, where the short-term exception does not apply, Real Estate Professional Status (REPS) under IRC Section 469(c)(7) offers a path to full loss deductibility. REPS requires meeting two annual conditions:

1. More than 750 hours of personal services in real property trades or businesses in which you materially participate
2. Those hours must represent more than 50% of your total personal service hours for the year across all activities

This is a meaningful threshold. For someone holding a full-time W-2 job, satisfying both requirements simultaneously is very difficult. For a full-time real estate investor or operator whose primary professional activity is property management, it is achievable. The 750-hour floor is absolute with no proration or exceptions.

IRS documentation requirements for REPS are stringent. Expect a contemporaneous log with dates, activities, duration, and property identification. If your REPS qualification is challenged in an examination, your log is your primary evidence. Start building it on January 1.

If you believe you qualify for the STR material participation exception or are exploring REPS, a CPA with real estate specialization is not optional. The tax savings are real, and the planning requirements are specific enough that general tax advice does not substitute for advice about your facts. The entity structure you hold your STR in also affects how deductions flow and how losses pass through, which is worth addressing in the same conversation.
