Short-term rental taxes come down to a handful of specific rules: how many days you rented, how many days you used the place yourself, how long the average guest stays, what services you provide, how you depreciate the building and the furniture, and whether your losses are passive or not. Get those six answers right and your CPA conversation takes one appointment instead of three. This article is educational, not tax advice. Rules change, and how they apply depends on your facts.

I have spent 18+ years in real estate, focused on short-term rentals since 2016, and built a list of more than 10,000 short-term rental operators through CashFlow Diary. The pattern I see is not operators cheating. It is operators who cannot describe their own activity in the language the tax code uses, so their return gets filed on autopilot by a preparer who has never seen a turnover schedule. Below is the framework, with every rule tied to a live IRS page. Take it to a qualified tax professional who knows short-term rentals, and make them show you their reasoning.
The 14-Day Rule and the Personal-Use Side of It
The rule hosts usually hear about as "the Augusta rule" is set out in IRS Topic No. 415: "There's a special rule if you use a dwelling unit as a residence and rent it for fewer than 15 days. In this case, don't report any of the rental income and don't deduct any expenses as rental expenses."
Two conditions, not one. You must use the unit as a residence, and you must rent it fewer than 15 days in the year. Publication 527 states it the same way: if you use a dwelling unit as a home and rent it less than 15 days during the year, "its primary function isn't considered to be rental and it shouldn't be reported on Schedule E (Form 1040)."
The personal-use side is where operators get surprised. Publication 527 defines a dwelling unit as used as a home when your personal use exceeds "the greater of 14 days, or 10% of the total days it is rented to others at a fair rental price." Once you cross that line and you rent 15 days or more, you must split expenses between rental and personal use by days, and your deductible rental expenses can be limited.
Run the math before you assume. Say your cabin rents 150 nights at fair rental price. Ten percent of 150 is 15, and 15 is greater than 14, so your threshold is 15 nights. Stay 12 nights yourself and you have not used it as a home. Stay 20 and you have. Now change the rental nights to 120. Ten percent is 12, which is less than 14, so the threshold falls back to 14 nights — and the same 20 nights of personal use puts you over it. Fewer rental nights means a lower personal-use ceiling. Track nights in writing all year, not in April.
Your situation | Where income goes | What you can deduct |
|---|
Personal residence, rented fewer than 15 days | Not reported as rental income | No rental expenses |
Rented 15+ days, personal use at or under the greater of 14 days / 10% of rental days | Schedule E (unless substantial services) | Rental expenses, subject to loss rules |
Rented 15+ days, personal use over that threshold | Schedule E, treated as used as a home | Expenses split by days and capped by rental income |
Substantial services provided to guests | Schedule C | Business expenses, plus self-employment tax exposure |
Schedule E or Schedule C, and Why It Costs Money
Most rental real estate lands on Schedule E, which is not subject to self-employment tax. Short-term rentals can land somewhere else. Publication 527 says it plainly: "Generally, Schedule C is used when you provide substantial services in conjunction with the property or the rental is part of a trade or business as a real estate dealer."
The publication then defines the trigger: "If you provide substantial services that are primarily for your tenant's convenience, such as regular cleaning, changing linen, or maid service, you report your rental income and expenses on Schedule C." It also draws the other edge: "Substantial services don't include the furnishing of heat and light, cleaning of public areas, trash collection, etc." And it warns of the consequence — "you may have to pay self-employment tax on your rental income."
So the question is not whether you list on Airbnb. It is what you hand the guest. Mid-stay housekeeping, daily linen service, breakfast, guided tours, and an on-site attendant push toward Schedule C. Cleaning between stays, utilities, and supplying a stocked kitchen do not, on their own, look like hotel service. Where your operation sits is a facts-and-circumstances call, which is exactly the call a CPA is paid to make and to document.
The failure mode I see most often is an operator who upsells concierge services all season, reports on Schedule E out of habit, and has no memo explaining why. The fix is a one-page written description of every service you provide, refreshed each year, sitting in the file before the return is prepared.
The Deduction List Most Operators Under-Claim
Publication 527 sets the standard: "In most cases, the expenses of renting your property, such as maintenance, insurance, taxes, and interest, can be deducted from your rental income," and you can deduct "ordinary and necessary expenses for managing, conserving, or maintaining rental property from the time you make it available for rent."
That last clause matters. The clock starts when the unit is available for rent, not when the first guest books. The IRS rental guidance for small businesses lists deductible categories including mortgage interest, property tax, operating expenses, depreciation, and repairs.
Expense category | Typical STR examples | Watch-out |
|---|
Operating | Cleaning fees paid out, supplies, consumables, laundry | Keep guest-stay cleaning separate from your own personal-stay cleaning |
Platform and software | Host service fees, channel manager, rate automation tools, lock software | Fees are often netted out of payouts — read the gross payout report |
Occupancy and property | Insurance, HOA dues, utilities, internet, landscaping, pest control | Split by days if the unit had personal use |
Interest and taxes | Mortgage interest, property tax | Personal-use portion is handled under the home rules |
Repairs vs. improvements | Fixing a leak vs. a new roof | Repairs are deducted; improvements are capitalized and depreciated |
Travel and professional | Trips to the property for management, CPA and legal fees | Document business purpose per trip; personal side-trip days do not count |
Depreciation | Building, furnishings, appliances | Not optional in practice — basis is reduced whether or not you claim it |
Two categories where I see real money left behind (and a reminder that gross and net are not the same number): pre-rental expenses in the weeks after the unit is listed but before the first booking, and furnishings bought in a single big spend at launch that never get split out from the building on the depreciation schedule.
Depreciation, Furnishings, and What Cost Segregation Really Is
Residential rental property is depreciated over 27.5 years under the general depreciation system, per Table 2-1 in Publication 527. Land is not depreciated. Publication 527's own worked example shows the mechanics: a $160,000 basis placed in service in February of Year 1 gets a 3.182% first-year percentage, for a $5,091 deduction.
The same table puts most of what you actually bought for the unit on a far shorter clock. Table 2-1 assigns 5 years under the general depreciation system to furniture used in rental property, to appliances such as stoves and refrigerators, and to carpets. Office furniture and equipment such as desks and files get 7 years. Land improvements such as fences get 15 years. Your beds, sofas, range, and rugs are not the building, and they should not sit on a 27.5-year line. If you want the wider picture on first-year write-offs of that short-lived property, I covered the current bonus depreciation rules in this breakdown for real estate investors.
Cost segregation separates a property's cost into building, land improvements, and shorter-lived personal property so each piece gets its correct recovery period. It does not create a deduction out of nothing; it changes the timing of deductions you were going to get anyway.
Here is the cost/benefit. A study is a paid engineering-and-accounting engagement, typically quoted per property, and it makes sense when three things are true at once: the property basis is large enough that reclassification moves meaningful dollars, you have income the accelerated deductions can actually offset this year or next, and you expect to hold long enough that recapture on a near-term sale does not erase the benefit. If you have a modest-basis condo, no offsetting income, and a two-year hold plan, a study can cost more than it returns. You will see marketing that quotes a flat first-year savings number. Treat it as a sales illustration built on someone else's property, not a forecast of your result — your result depends on your basis, your component mix, your income, and your hold period. Ask the provider for a written estimate of reclassified percentages and the fee, then have your CPA model your actual tax at your actual rate.
Passive Losses, Material Participation, and the Short-Term Rental Exception
Rental losses run into the passive activity loss rules in Publication 925: passive losses generally offset only passive income. There is a limited exception — Publication 925 describes a special $25,000 allowance for certain rental real estate activities with active participation, subject to a phaseout rule.
Material participation is the higher bar. Publication 925 lists the tests, including these: "You participated in the activity for more than 500 hours." "Your participation was substantially all the participation in the activity of all individuals for the tax year, including the participation of individuals who didn't own any interest in the activity." "You participated in the activity for more than 100 hours during the tax year, and you participated at least as much as any other individual (including individuals who didn't own any interest in the activity) for the year." There are additional tests covering significant participation activities, prior-year participation in 5 of the last 10 years, and personal service activities.
Now the part short-term rental operators care about. Publication 925 excludes certain activities from the definition of a rental activity, including where "the average period of customer use of the property is 7 days or less." The publication explains how to compute it: "You figure the average period of customer use by dividing the total number of days in all rental periods by the number of rentals during the tax year." A second exclusion applies when the average period of customer use "is 30 days or less and you provide significant personal services with the rentals."
In plain terms: an average guest stay of 7 days or less keeps the activity out of the automatic rental-activity bucket, but it still has to clear a material participation test on its own to be non-passive. Two hurdles, and documentation decides the second one.
Question | Where it is answered | What turns on it |
|---|
Average guest stay 7 days or less? | Pub. 925, exceptions to rental activity | Whether the automatic rental-activity treatment applies |
Do you meet a material participation test? | Pub. 925, material participation tests | Whether losses are non-passive |
Do you provide substantial services? | Pub. 527, Schedule C discussion | Schedule E vs. Schedule C and self-employment tax |
Personal use over the 14-day / 10% threshold? | Pub. 527, dwelling unit used as a home | Expense allocation and deduction limits |
Two cautions. First, the hours test is about your hours, and Publication 925 excludes work you do in an investor capacity and sets out proof-of-participation standards. If a full-service property manager runs the unit, the "substantially all" and "as much as any other individual" tests get hard fast. Second, this is educational, not tax advice, and the interaction of these rules with your other income is not something to settle from an article.
Occupancy Tax, Platform Remittance, and Records
Lodging or occupancy tax is a state and local matter, and it is separate from income tax. Airbnb collects and remits occupancy taxes automatically in some jurisdictions and not others, and publishes the list of where collection is available in its help center. Direct bookings, Vrbo listings, and channel bookings can each be handled differently in the same city. Confirm per platform, per jurisdiction, and keep the confirmation.
If the platform does not collect, you do. Registration, filing frequency, and remittance are on you, and each of those is set by the taxing jurisdiction, not by the platform. Get the rules from the city or state revenue office in writing rather than from a host forum.
On records, the IRS is direct: "You must be able to substantiate certain elements of expenses to deduct them," and good records help you monitor progress, prepare returns, and support items reported. Its rental guidance adds that you should keep records of rental income and expenses and documents supporting deductions such as receipts, canceled checks, and bills.
What I keep, per property, per year: a nights ledger with every stay, its length, and whether it was personal or guest use; gross platform payout reports, not the net deposits; a written list of services provided to guests; a contemporaneous log of my own hours with dates and task descriptions; and the depreciation schedule with the furnishings broken out. That packet is what makes a CPA cheap and an audit boring.
The CPA Conversation Playbook
Run this before you hire, not after you file.
Step 1 — Assemble the six facts
Nights rented, nights of personal use, number of separate rentals, total rental nights (for the average-stay math), services provided, and your documented hours.
Step 2 — Compute your average guest stay
Total nights in all rental periods divided by the number of rentals, exactly as Publication 925 describes. Write the number down.
Step 3 — Write the services memo
One page listing every service you or your team provide during a stay, with frequency. This is the document that answers the Schedule C question.
Step 4 — Interview the preparer with specifics
Ask how they compute average period of customer use, which material participation test they would apply to you and what proof they require, how they would handle furnishings versus structure, and whether they have modeled cost segregation for a property your size. Vague answers are your answer.
Step 5 — Get the position in writing
Ask for a short memo stating the treatment chosen and the facts it rests on. If the facts change next year, the memo is your starting point instead of a blank page.
If your unit is a single room you rent a few weekends a year, most of this article does not apply to you and a specialist CPA is probably not worth the fee. If you own two or more units, provide guest services, or plan to claim losses against other income, it applies to all of it. One more time: this is educational, not tax advice. Tax rules change, and your treatment depends on your specific facts. Verify with a qualified professional before you file.

Frequently Asked Questions
Does the 14-day rule mean I can always rent 14 nights tax-free?
No. IRS Topic No. 415 applies the rule when you use the dwelling unit as a residence and rent it for fewer than 15 days in the year. If you use the unit as a residence and stay under 15 rental days, you do not report the rental income and you do not deduct rental expenses. A property held purely as a rental is a different fact pattern, and the count resets each tax year.
Does having an average guest stay of 7 days or less make my losses non-passive?
Not by itself. Publication 925 excludes an activity from the rental activity definition when the average period of customer use is 7 days or less, but you still have to meet a material participation test — for example, more than 500 hours, or more than 100 hours and at least as much as any other individual — for the activity to be treated as non-passive.
Do I owe self-employment tax on short-term rental income?
It depends on whether you provide substantial services. Publication 527 says Schedule C is generally used when you provide substantial services in conjunction with the property, and that you may have to pay self-employment tax on that income. Regular cleaning during a stay, linen changes, and maid service are the examples given; heat, light, and trash collection are not substantial services.
Is cost segregation worth it for a single short-term rental?
Sometimes, and only after math. The study reclassifies parts of the purchase into shorter recovery periods, which accelerates deductions rather than creating new ones. It tends to pay when basis is large, you have income to offset now, and you plan to hold. Get the fee and the estimated reclassification in writing, then have your CPA model your actual result.
Who collects the occupancy tax on my bookings?
It varies by platform and jurisdiction. Airbnb collects and remits in the areas listed in its help center; elsewhere, and for direct bookings, registration and remittance are your responsibility. Check each platform for each property location and keep that confirmation on file.
