Short-term rental tax

The short-term rental strategy, priced and qualified before you buy.

Most of the writing about the short-term rental strategy is aimed at getting you excited. This page is aimed at telling you whether it works for you, what it actually costs, and what happens afterwards. It is written for owners of short-term rentals (an Airbnb, a Vrbo listing, or a property booked directly) who want a CPA to run the numbers before they commit.

The strategy is legitimate and well established. It is also oversold: a meaningful share of the people who ask about it should not do it. Both of those things are true at once.

What the strategy actually is

Short-term rental tax work, often shortened to STR, turns on two tests.

Normally, losses from a rental property are passive. You cannot use them against your salary or your business income; they sit and wait until you have passive income or you sell.

Short-term rentals can be different. If the average guest stay is short enough, the activity is not treated as a rental for the passive loss rules at all. It is treated like any other business you are involved in, which means that if you are involved enough, the losses are not passive, and they can offset ordinary income.

That is the whole idea. Everything else (the cost segregation study, the bonus depreciation) is about making the first-year loss large enough to be worth the exercise.

A cost segregation study breaks the building into its components. Instead of depreciating the entire structure slowly over decades, the study identifies the pieces that are properly treated as shorter-lived property: fixtures, flooring, appliances, cabinetry, and land improvements such as driveways, walkways and fencing. Those shorter-lived pieces are eligible for bonus depreciation, which is 100% and now permanent for qualifying property acquired after January 19, 2025. If you signed a binding contract to buy before January 20, 2025, older and lower percentages still apply.

Two limits worth knowing up front. Bonus depreciation never applies to the building itself, only to the shorter-lived components. And land is never depreciable at all, nor is general landscaping tied to the land rather than to a building.

Whether you qualify: two tests, both required

People get this wrong constantly, usually by satisfying one test and assuming they are done.

1. The average stay has to be short

The property’s average period of customer use for the year has to be seven days or less. Not most bookings: the average across the year. One long winter booking can pull the average over the line and undo the whole strategy.

This is arithmetic, and it is the test people fail without realizing it. Run the number before December, not in April.

2. You have to materially participate

You have to be genuinely involved in operating the property. There are several ways to satisfy this; the ones that matter in practice are performing substantially all of the work yourself, or spending more than 100 hours on it with no one else spending more than you do.

The trap is who counts as “anyone else.” It is not just other owners. Cleaners, co-hosts, handymen and property managers all count against you. A full-service manager usually spends more hours than the owner does, which closes that route entirely. This is the most common reason the strategy fails.

Investor-type hours also generally do not count: researching, reviewing statements, monitoring performance. That exclusion falls away if you are genuinely involved in day-to-day operations.

And note the order of operations. Clearing the seven-day test does not by itself make the loss deductible. It only removes the automatic “rental means passive” label. You still have to clear material participation, and then basis, at-risk and excess business loss limits, in that order.

SHORT-TERM RENTAL TAX

Run the numbers before you buy, not after

The best time to have this conversation is before you close on the property, because the purchase price, the closing date and how you plan to manage it all change the answer. A short call tells you whether the strategy works for your situation and roughly what it is worth.

You can get a first read yourself: the short-term rental tax savings calculator works out what a cost segregation study is worth in year one at 2026 rates, after the section 461(l) cap.

What this actually costs

Nobody publishes this, so here it is. There are two separate bills, and they go to two different places.

What Who you pay Typical cost
Cost segregation study: engineered, with site inspection
The thorough version. Appropriate for larger or more complex properties.		 Specialist study firm $3,000–$4,000
Cost segregation study: virtual
No site visit. Appropriate for smaller properties, roughly $300,000 and under.		 Specialist study firm $1,000 or less
CPA fees: implementing it on your return
Applying the study, the bonus depreciation election, the passive activity analysis, and an otherwise straightforward personal return with the rental on Schedule E.		 Us $1,500–$2,000

So a typical first year is roughly $2,500 to $6,000 all in, depending on which study your property warrants.

Our fee covers a standard short-term rental reported on Schedule E alongside an otherwise straightforward personal return. It does not include a business return. If the property sits in a partnership or S corporation that files its own return, that is separate. Multiple properties, messy books, or a complicated personal return are quoted individually.

A note on the study firms. We do not perform cost segregation studies and we do not take referral fees for them. Study quality varies enormously and a weak study is a liability, not an asset, because it is the document that has to hold up if anyone asks. We will tell you which kind your property warrants and who does credible work.

Is it worth it? A rough sense of scale

The deduction is driven by how much of your purchase price reallocates to shorter-lived components. How much that is depends entirely on the property and its finishes. A study is the only way to know, and anyone quoting you a percentage before seeing the property is guessing. We can run a preliminary estimate before you commit to anything.

To give a sense of the mechanics rather than a promise: if a study reallocated $150,000 of a purchase to components eligible for bonus depreciation, that is a $150,000 first-year deduction from the reallocation. For someone in a 35% bracket that is roughly $52,000 of tax deferred, against a total cost of a few thousand dollars. That is the shape of why people do this.

Three limits sit on top of it:

  • Land is not depreciable, and neither is the building shell for bonus purposes. Only the shorter-lived components qualify.
  • There is a ceiling on how much loss you can use in one year. For 2026, the excess business loss threshold is $256,000, or $512,000 on a joint return. Loss above that is not lost: it carries forward as a net operating loss, but it is not available this year.
  • Basis and at-risk limits come first. A heavily financed property can run into those before the excess business loss cap is ever reached.

The part that gets left out: what happens on sale

This is a timing benefit, not a permanent one. Depreciation you take now reduces your basis, and when you sell, that comes back as recapture.

The pieces reclassified as personal property (appliances, carpeting, cabinetry) come back as ordinary income, at your regular rate. The building portion is taxed at a rate of up to 25%. Neither gets capital gains treatment.

That does not make the strategy bad. Deferring tax for years is valuable, and there are ways to manage the sale. But you should go in knowing that a large first-year deduction is a loan against a future tax bill, not a gift.

Who this is not for

You use a full-service property manager and do not want to change that. If the manager works more hours on the property than you do, the most common participation route closes. This is the single most frequent reason the strategy fails.

Your average stay is not actually short. Monthly or seasonal bookings pull the average over seven days. Mid-term rentals are a different strategy with different rules.

You use the property yourself a fair amount. If your personal use exceeds the greater of 14 days or 10% of the days it is rented at a fair rate, a separate set of rules caps your deductions at the rental income. There is no loss left to deduct, and the rest of this analysis stops mattering. A vacation home you also rent out is the classic case. Worth checking before anything else.

You plan to sell within a few years. Recapture arrives quickly and much of the benefit unwinds.

Your income is modest. If you are not in a high bracket, a large deduction is worth proportionally less and the fixed costs eat the benefit.

You will not keep records. If you know you will not log hours during the year, this is not a strategy, it is an exposure.

We would rather tell you no in a fifteen-minute call than prepare a return that does not survive scrutiny. Disqualifying people honestly is part of the service.

How a first year runs

When What happens
Before you buy, ideally We look at the purchase price, the expected closing date, how you intend to manage the property and your income picture, and give you a realistic estimate of the benefit.
At closing The property has to be placed in service, ready and available for rent, in the tax year you want the deduction. Late-December closings are tight and the timing detail matters.
First month We set up the participation log and tell you exactly what to record. This is the step that protects everything else.
During the year You keep the log. We are available for the questions that come up: a long booking that would break the average, a manager arrangement that would break participation.
After year end Study is commissioned if it has not been already, we apply it, run the passive activity analysis, and prepare the return.

Frequently asked questions

How much does a cost segregation study cost?

It depends on which kind your property warrants. An engineered study with a site inspection generally runs $3,000 to $4,000. A virtual study (no site visit, appropriate for smaller properties, roughly $300,000 and under) is generally $1,000 or less. That fee goes to the specialist firm performing the study. Our CPA fee for applying the study to your return is separate, at $1,500 to $2,000 for a standard short-term rental on Schedule E with an otherwise straightforward personal return.

What do you charge to do a short-term rental return?

$1,500 to $2,000 for a standard short-term rental reported on Schedule E, including implementing the cost segregation study and the bonus depreciation election, together with an otherwise straightforward personal return. That does not include the cost segregation study itself, which is paid to the study firm, and it does not include a business return. If the property sits in a partnership or S corporation filing its own return, that is quoted separately. Multiple properties or a complicated personal return are quoted individually.

Can a short-term rental loss really offset my W-2 income?

Yes, if two things are both true. The property’s average period of customer use for the year has to be seven days or less, which takes it outside the rental category for the passive loss rules. And you have to materially participate in operating it. Meet both and the loss is not passive, so it can offset ordinary income including salary, subject then to basis, at-risk and excess business loss limits. Meet only one and it cannot. The second test is where most people fail, usually because a property manager or cleaning team spends more hours on the property than the owner does.

Do I need to be a real estate professional?

No, and this is the most useful thing to understand about the strategy. Real estate professional status is a demanding test built around hours spent in real property trades or businesses, and most people with a full-time job cannot meet it. The short-term rental route does not require it. That is precisely why it is attractive to high-earning professionals who could never qualify as real estate professionals.

What if I use a property manager?

It depends on what they do and how much. The participation route most owners rely on requires that no one else spends more hours on the activity than you do, and ‘no one else’ means everyone, not just other owners. Cleaners, co-hosts, handymen and managers all count against you. A full-service manager handling bookings, guest communication, cleaning coordination and maintenance will usually exceed your hours, which closes that route. A limited-scope arrangement often does not. This is worth working through before you sign a management agreement, not after.

Is the deduction permanent?

No. It is a timing benefit. Depreciation reduces your basis in the property, and when you sell it comes back as recapture. The components reclassified as personal property (appliances, carpeting, cabinetry) come back as ordinary income at your regular rate, and the building portion is taxed at a rate of up to 25%. Neither gets capital gains treatment. Deferring tax for a number of years is genuinely valuable, and there are ways to manage the eventual sale, but a large first-year deduction is best understood as a loan against a future tax bill rather than money you keep.

When does the property have to be in service?

It has to be placed in service, meaning ready and available for rent, during the tax year you want the deduction. Buying in a year is not the same as placing in service in that year. Late-December closings are tight, and if the property is not genuinely ready and available before year end the deduction moves to the following year. This is worth planning around rather than discovering in April.

Can I do this on a property I already own?

Often yes. A cost segregation study can be performed on a property you have held for some years, and the depreciation you should have been taking can generally be caught up in full in the current year by filing Form 3115 (a change in accounting method) rather than by amending prior returns. One condition: the property generally needs to have been on the books for at least two years for that route to be available; if you simply missed depreciation in the first year, the fix is an amended return instead. Whether it is worth doing depends on your basis, how long you have held it, and whether you meet the participation tests now.

What records do I need to keep?

A contemporaneous log of the time you spend on the activity: the date, what you did, and how long it took. Keep it during the year, not afterwards. If your participation is ever examined, the question will not be whether you did the work but whether you can show it, and a log written during the year is what survives. We set this up with clients in the first month of the engagement.

Does it matter if I use the property myself?

Yes, and it is worth checking before anything else. If your personal use of the property exceeds the greater of 14 days or 10% of the days it is rented at a fair rental rate, a separate set of rules limits your deductions to the rental income the property produces. There is no loss left to offset anything, and the rest of the analysis becomes moot. Separately, if you rent the property fewer than 15 days in the year, the rental income is simply excluded and no deductions are allowed. A vacation home you also rent out is the case that trips people up.

What does an STR CPA do that a general preparer does not?

The work sits in the decisions rather than the data entry. Whether the average guest stay puts the activity outside the rental rules, which material participation test your hours can actually meet, whether a cost segregation study is worth commissioning and at what depth, how bonus depreciation interacts with the excess business loss limit, and what recapture will cost when the property sells are all positions, and they are taken before the return is prepared. The difference is mostly timing: a preparer engaged in March is reporting decisions that were already made, and by then most of them can no longer be changed.

Does it matter whether the property is listed on Airbnb, Vrbo or booked directly?

The platform does not change the tax analysis. What decides the treatment is the average length of a guest’s stay and how involved you are in running the property, and those two tests apply whether the bookings come through Airbnb, Vrbo, a manager’s site or directly, and any accountant looking at the return will start there. What the platform does change is the paperwork. A 1099-K reports gross amounts that can include service and cleaning fees, so it rarely matches what reached your account, and the return has to reconcile the difference.
