Running a short-term rental on Airbnb or VRBO means you are operating a small hospitality business — and the IRS treats it that way. The expense list is long, the depreciation deductions can be substantial, and for hosts who manage their own properties, there is a significant opportunity to offset those losses against ordinary income. The catch is that the biggest tax benefits require documented management time. Here is what you need to know.
Before you can write off a single dollar of expenses, you need to understand how the IRS classifies your property. Under IRC §280A, the deductibility of your short-term rental expenses depends heavily on how many days you personally used the property versus how many days it was rented.
For STR investors using their properties as true income-generating assets — not vacation retreats with occasional rentals — keeping personal use below 14 days (or the 10% threshold) preserves full deductibility and unlocks the most valuable tax treatment.
If your property crosses the personal-use threshold, expenses must be allocated between rental and personal use. The IRS method divides rental days by total days used (rental + personal). A property rented 120 days and personally used 30 days had 150 total use days, so 80% of expenses are deductible as rental costs.
However, there is a taxpayer-favorable alternative method established in Bolton v. Commissioner: allocate mortgage interest and property taxes using rental days divided by total days in the year (including idle days). This often produces a higher rental allocation — and therefore larger deductions — for these fixed costs. Your CPA can calculate which method yields the better outcome for your situation.
Note that even under the more favorable allocation, mixed-use properties cannot generate a net loss. Deductions are capped at gross rental income, with excess carrying forward to future years.
Assuming your property qualifies as a pure rental (personal use at or below the 14-day threshold), the following expenses are deductible against rental income:
Depreciation is typically the single largest deduction available to STR owners — and the one most often missed or miscalculated. The IRS allows you to deduct the cost of the building (not land) over its useful life: 27.5 years for residential rental property.
On a property purchased for $400,000 where $80,000 is allocated to land, the depreciable basis is $320,000. Annual straight-line depreciation is roughly $11,636. That is a paper deduction that reduces your taxable income without any cash outlay.
Short-term rental properties may qualify for cost segregation studies, which reclassify portions of the building into shorter depreciation categories (5-year, 7-year, or 15-year property). Combined with bonus depreciation (100% in 2022, phasing down in subsequent years), a cost segregation study can generate massive front-loaded deductions in the year of purchase. For a $500,000 property, it is not uncommon to segregate $80,000–$120,000 into accelerated categories.
Cost segregation is most valuable when you can actually use the losses — which requires clearing the passive activity rules. This is why material participation documentation matters so much for STR investors considering cost seg.
Furniture, appliances, and equipment used in the rental are depreciated over 5–7 years and may be eligible for full expensing under Section 179 or bonus depreciation, subject to annual limits and phase-down schedules.
Most Airbnb and VRBO income is reported on Schedule E (Supplemental Income and Loss), the same form used for long-term rentals. Schedule E income is not subject to self-employment tax, which is a meaningful advantage — SE tax can be 15.3% on top of income tax.
However, if you provide substantial services to guests beyond what is customary for a rental — daily maid service, concierge, meals, or hotel-style amenities — the IRS may treat your STR as an active trade or business, requiring Schedule C (Profit or Loss from Business). Schedule C income is subject to self-employment tax, but it also allows you to contribute to a SEP-IRA or Solo 401(k) based on earned income from the rental.
IRC §280A(g) — informally called the Augusta Rule after the practice of homeowners near Augusta National renting their homes during the Masters tournament — provides that if you rent your personal residence for 14 days or fewer in a calendar year, the rental income is completely excluded from gross income and does not need to be reported.
This rule applies to your primary residence or a second home that you also use personally. If you own a vacation home and rent it for exactly 14 days during peak season at premium rates, you pocket that income tax-free.
There is also a business application that some tax advisors explore: business owners may be able to rent their personal residence to their own S-corporation or LLC for business meetings, potentially generating deductible business expenses for the company while receiving tax-free rental income personally. This strategy requires careful implementation and documentation to withstand scrutiny.
The tradeoff: properties that qualify for the Augusta Rule (14 days or fewer of rentals) cannot deduct rental expenses beyond mortgage interest and property taxes. The tax-free treatment and the expense deductions are mutually exclusive. For hosts aiming to maximize deductions, renting more than 14 days and keeping personal use low is the better strategy.
The most powerful tax opportunity for STR hosts is not any individual deduction — it is using the aggregate of all deductions (especially depreciation) to generate a net paper loss and then applying that loss against W-2 wages or business income to reduce your overall tax bill.
Under normal passive activity rules, rental losses are passive and can only offset passive income. But two pathways can unlock these losses for current-year use:
Both pathways hinge on the same critical requirement: documented hours. You must be able to prove, with contemporaneous records, how much time you personally spent managing the property. Without that documentation, the IRS can disallow the loss deduction entirely.
For a short-term rental that has cleared the 7-day average, material participation is governed by the same seven tests that apply to other trade or business activities. The most commonly used tests for STR hosts are:
Hours that count include guest communications, cleaning coordination (even if a cleaner does the physical work), maintenance oversight, restocking supplies, listing management, pricing and calendar updates, and financial management of the property.
The IRS is fully aware that the STR loophole is frequently used — and sometimes abused. Short-term rental loss deductions against ordinary income are a known audit trigger. When an examiner looks at your return and sees rental losses offsetting W-2 income, the first questions will be: What was your average rental period? And how do you know you materially participated?
Tax court cases have repeatedly upheld the IRS on this point. Taxpayers who reconstruct their hours at tax time from memory, credit card statements, and rough estimates regularly lose. Courts look for contemporaneous records — logs kept at or near the time the work was performed.
What contemporaneous records look like in practice: a log entry for every significant management activity, showing the date, what was done, which property it related to, and how long it took. Ideally accompanied by corroborating evidence — guest message threads, contractor invoices, supply receipts, calendar entries.
The IRS expects contemporaneous records of your management time. REPSAgent lets STR hosts log every guest communication, cleaning coordination, and maintenance task in seconds — so your material participation is documented before an auditor asks.
