Short-Term Rental Tax Deductions: An Operator's Guide

TL;DR: Once your property is a rental business, the IRS lets you deduct every "ordinary and necessary" cost of running it — cleaning, supplies, platform commissions, software, and the property itself through depreciation. The deductions that actually move your taxable income are depreciation (especially bonus depreciation and cost segregation) and, if your average guest stay is seven days or less and you materially participate, the ability to offset losses against other income. This guide covers what's deductible, the rules that trip operators up, and one deduction worth shrinking on purpose.

What counts as a short-term rental tax deduction

The moment you list a property on Airbnb, Vrbo, or your own site and rent it for more than 14 days a year, the IRS stops seeing a personal asset and starts seeing a business. That reclassification is the whole game: it unlocks your right to write off the "ordinary and necessary" expenses of operating the rental against the income it produces.

This isn't an April scramble for receipts. The operators who keep the most are the ones who treat tax strategy as a year-round line item — categorizing spend as it happens, tracking rental-vs-personal days, and knowing which costs hit the books now versus over time. Here's how to think about it like an operator running a P&L, not a host filing a hobby return.

The deduction categories that matter, at a glance

Category	What's in it	When you deduct it
Operating expenses	Cleaning, property management fees, guest supplies, marketing, utilities	Same year
Property carrying costs	Mortgage interest, property taxes, insurance	Same year (prorated if mixed-use)
Repairs & maintenance	Fixing a faucet, patching drywall, repairing an appliance	Same year
Capital improvements	New roof, renovation, furniture, appliances	Over time, via depreciation
Platform commissions & fees	Airbnb/Vrbo service fees, booking commissions	Same year (100% deductible)

Mortgage interest is the single largest write-off for most owners, especially in the early years of a loan when interest dominates the payment. But the deductions with real strategic leverage — depreciation and the STR loophole — are further down. We'll get there.

How your property use changes everything

Before you write off a single welcome basket, answer one question: is this a dedicated rental, or a property you also use personally? That ratio dictates how you split shared expenses, and getting it wrong is the most common way operators overstate deductions.

The 14-day rule

• Rented 14 days or fewer (and you personally use it more than 14 days): you don't report the rental income, and you can't deduct rental expenses. The IRS treats it as a tax-free personal use.
• Rented more than 14 days: it's a rental business. You report all the income, and you unlock the deductions.

A common myth: days you spend on-site doing repairs or maintenance count as "personal use" days. They don't. Block off a weekend to fix the plumbing and repaint a guest room, and those days won't dilute your rental-use percentage.

Prorating mixed-use expenses

If the property does double duty (and you use it personally for more than 14 days), you can't deduct the full annual cost of shared expenses like mortgage interest, taxes, and insurance. Allocate them by use.

The math: rental days ÷ total use days = your rental-use percentage. Rent it 100 days, use it personally 25 days, and your rental-use percentage is 80% (100 ÷ 125). You deduct 80% of those shared costs. Expenses that are 100% for guests — cleaning between stays, platform commissions, towels bought only for guests — are fully deductible regardless.

Depreciation: the deduction most operators get wrong

Day-to-day operating costs are the easy wins. The deductions that meaningfully cut a taxable income are larger, slower, and routinely misunderstood — starting with how long you depreciate the building.

27.5 years or 39 years? It depends on average stay

You'll see "39 years" repeated all over STR blogs as if it's settled. It isn't — and citing it blindly can cost you. The recovery period for the building depends on your average guest stay:

• Average stay of more than 30 days: the property is residential rental property, depreciated over 27.5 years.
• Average stay of 30 days or less: the IRS treats it as nonresidential (more like a hotel), depreciated over 39 years.

The physical structure doesn't decide this — usage does. A single-family home rented nightly is nonresidential property under the code if the average stay is 30 days or fewer. Most STR operators land in the 39-year bucket, but plenty with monthly mid-term tenants don't. Check your booking data before your CPA assumes one or the other. (See IRS Publication 527 for residential rental property rules.)

Bonus depreciation is back to 100% — and now permanent

Here's the kicker: the building's recovery period barely matters for the assets inside it. Furniture, appliances, flooring, and decor have recovery periods of 20 years or less, which makes them eligible for bonus depreciation — deducting the full cost in year one instead of spreading it out.

Under the One Big Beautiful Bill Act, signed July 2025, 100% bonus depreciation was restored and made permanent for qualifying property placed in service after January 19, 2025 (the prior phase-down to 60% in 2024 and 40% in early 2025 was struck from the code). This replaces the old "100% through 2029" framing you may have read — it's no longer a sunsetting window. Source: IRS guidance on depreciation and expensing.

Practically: furnish a new STR for $20,000 in furniture, appliances, and TVs placed in service in 2026, and you can potentially deduct the entire $20,000 against rental income that year instead of $3,000–$4,000.

Cost segregation, for operators with scale

For larger or higher-value properties, a cost segregation study has an engineering firm reclassify building components — specialty lighting, carpeting, landscaping, certain plumbing — into 5-, 7-, and 15-year buckets instead of the 27.5- or 39-year building life. Paired with bonus depreciation, that front-loads a large chunk of the property's cost into year one. It costs money upfront, so it pays off on properties where the accelerated deduction clears the study fee — typically purchases well into the six figures.

A concrete example: how deductions move your taxable income

Numbers make this real. Take one mid-tier STR, full year, average stay under 30 days:

Line item	Amount
Gross rental revenue	$80,000
Platform commissions & service fees	−$12,000
Cleaning, supplies, utilities	−$14,000
Mortgage interest, taxes, insurance	−$22,000
Repairs & software	−$4,000
Cash operating profit	$28,000
Furniture/appliance bonus depreciation (year one)	−$20,000
Building depreciation (~$300K basis, 39 yr)	−$7,700
Taxable income (on paper)	$300

You cleared $28,000 in real cash, but depreciation — a non-cash deduction — drives taxable income to near zero. That's the leverage. And if your average stay is seven days or less and you materially participate, that paper loss can do even more (next section).

The STR loophole: offsetting other income

This is the strategy serious operators build around. Two IRS concepts unlock it:

• The 7-day rule. If your average guest stay is seven days or fewer, the activity isn't automatically treated as a "rental activity" under IRC Section 469's passive-activity rules. It's treated more like an operating business.
• Material participation. You prove you're involved on a "regular, continuous, and substantial" basis — commonly by working 100+ hours and more than anyone else, or 500+ hours a year on the property.

Clear both, and your rental losses are non-passive — meaning a depreciation-driven paper loss can offset W-2 wages and other active income, without needing Real Estate Professional Status. That's why a year like the example above, amplified by a cost segregation study, can shelter tens of thousands in outside income. This rests on longstanding Section 469 regulations, not an aggressive position — but the documentation bar is real, so log your hours. (More at TaxAct's STR loophole breakdown.)

The deduction worth shrinking on purpose: OTA commissions

Every deduction above lowers your tax bill on income you've already earned. Platform commissions are different — they're a deduction you should actively want to make smaller, because they're real cash leaving the building.

Look back at the example: $12,000 in Airbnb and Vrbo commissions on $80,000 of revenue. Yes, it's 100% deductible. But a deductible expense isn't a free one — you're still only recovering your marginal tax rate on it, maybe 25–35 cents on the dollar. The other 65–75 cents is gone to the OTA. Deducting commissions softens the blow; it doesn't change the fact that a 15% take is the single largest controllable line on most STR P&Ls.

The move professional operators make is to shift repeat and direct-search bookings off the OTAs and onto their own booking channel. A guest who books through your site costs you a payment-processing fee instead of a double-digit commission — the difference flows straight to margin. This is exactly the gap hostFront is built to close: giving operators a direct-booking website and engine so more of that $80,000 arrives commission-free. You'll still deduct the commissions you do pay; you'll just have fewer of them to deduct.

Don't forget the rest of your operating deductions

The categories below are smaller individually but add up fast across a portfolio:

• Property services: cleaning crews and management fees (100% deductible), landscaping, pool care, pest control, and security monitoring.
• Guest supplies: coffee, toiletries, welcome baskets, and replacement linens. Minor per item, but thousands a year across dozens of stays.
• Marketing & software: listing photography, ads, dynamic-pricing tools, channel managers, and accounting subscriptions.
• Professional fees: the lawyer who drafts your rental agreement and the CPA who files your return.
• Licensing: if your city requires a permit or business license to operate, that fee is a deductible operating expense.

Frequently asked questions

Can I deduct travel to my rental property?

Yes, if the trip's primary purpose is managing the rental — overseeing a renovation, hiring a cleaning crew, inventory checks. Flights or mileage, lodging for the work portion, and a percentage of meals can qualify. If the trip mixes work and vacation, deduct only the business days, and keep a daily log to back it up.

What records do I need to keep?

An undeniable paper trail for every dollar claimed: receipts, invoices, and matching bank or card statements; mortgage interest statements (Form 1098), property tax bills, and insurance policies; and a usage calendar tracking every rented night versus every personal night. That last log is what justifies your proration percentage and, if you're pursuing the STR loophole, your material-participation hours.

How do deductions work when I use the property personally?

Split shared expenses by the rental-use percentage: rental days ÷ (rental days + personal days). Rented 90 days, personal 10 days, total 100 — you deduct 90% of indirect costs like mortgage interest, taxes, and utilities. Guest-specific costs like cleaning and commissions stay 100% deductible.

When should I hire a tax professional?

When the strategy gets real: more than one property, a planned cost segregation study, or a shot at the STR loophole. A CPA who specializes in real estate will find deductions you'd miss and keep aggressive positions defensible — usually saving far more than the fee.
