Real Estate Tax Strategy for Business Owners
The depreciation is easy to generate. Making it usable against your business income is the entire problem.
Real estate tax strategy for business owners is the use of property depreciation, particularly accelerated depreciation from cost segregation, to offset income from an operating business. Generating the deduction is straightforward. The difficulty is the passive activity rules under Section 469, which by default prevent rental losses from offsetting business income. Every strategy in this area is ultimately about getting through that constraint.
The Constraint That Defines Everything
Rental activity is passive by default under Section 469, regardless of how involved the owner is. Passive losses can offset passive income, and generally nothing else. They are not lost when they cannot be used; they are suspended and carried forward until there is passive income to absorb them or the property is sold in a fully taxable transaction.
This is why so many business owners feel that a cost segregation study underdelivered. The study did its job: it produced a $400,000 first-year deduction. The deduction then sat suspended, because the owner had $800,000 of active business income and no passive income for it to offset. The failure was not the study. It was that nobody asked, before commissioning it, whether the loss would be usable.
There are four routes through, and every real estate strategy for a business owner is one of them.
Route One: Property Used in Your Own Business
The cleanest route, and the most overlooked. Where the property is used in a trade or business the owner materially participates in, it is not a passive rental activity, and depreciation offsets active business income directly.
For an owner whose company operates from a building they own, this makes cost segregation unusually attractive: the passive question largely falls away and the hold period is naturally long, because the business is not moving.
Where the building sits in a separate entity leasing to the operating company, the self-rental rules apply and produce an unhelpful asymmetry: net rental income is recharacterized as non-passive while a net rental loss generally stays passive. The grouping election resolves this by treating the rental and the operating business as one activity where they form an appropriate economic unit. That election needs to be made deliberately and documented, not discovered afterward.
Route Two: Short-Term Rentals
An activity where the average period of customer use is seven days or less is not a rental activity under the Section 469 regulations. That sounds like a technicality and it is a significant one: the property escapes the automatic passive classification, so the owner needs only to materially participate to treat the losses as non-passive.
Material participation is generally met through more than 500 hours in the activity, or by being substantially all of the participation by anyone, which is often achievable for a self-managed property. Critically, real estate professional status is not required, which is what makes this route available to a business owner who could never satisfy the REPS tests.
The average stay is computed across the year, so a property with mostly short bookings and a few monthly stays can fail the test. Using a full-service management company also undermines material participation, because the hours belong to the manager.
Route Three: Real Estate Professional Status
REPS under Section 469(c)(7) removes the automatic passive classification from all rental activities. It requires more than half of all personal services in trades or businesses to be in real property trades or businesses, plus more than 750 hours in them.
A business owner working full time in their own company essentially cannot meet the more-than-half test. The practical route is a spouse who qualifies: the tests are applied per spouse, so one qualifying spouse is enough, and the benefit lands on the joint return where it can offset the other spouse's business income.
This position is examined regularly and turns on contemporaneous documentation rather than on the underlying facts. Reconstructed logs routinely fail.
Route Four: Generating Passive Income
The least discussed and sometimes the most practical. Suspended passive losses can offset passive income from any source, so an owner sitting on a large suspended balance can acquire passive income producing investments and free the losses.
This suits an owner who already has substantial suspended losses from prior studies. It is a way of recovering value that has already been created rather than a reason to buy property, and the investment has to make sense on its own terms first.
What Cost Segregation Contributes
Cost segregation is the engine behind most of these strategies. A study separates a building's cost into components and reassigns them from the default 27.5 or 39-year schedules to their correct 5, 7, and 15-year classifications. With 100 percent bonus depreciation permanent under the OBBBA for property acquired after January 19, 2025, every reclassified dollar becomes immediately deductible.
Typical reclassification runs 20 to 35 percent of depreciable basis for commercial property and 15 to 25 percent for residential rental. Short-term rentals often sit at the higher end because furnishings and finishes are substantial relative to the structure.
The deduction is acceleration rather than creation. Basis claimed now is not available later, and depreciation recapture applies on sale, which is why a planned sale within two to three years usually argues against a study.
The Combination That Works Most Often
For a business owner with high active income and no realistic path to REPS, the most common effective structure is a self-managed short-term rental combined with a cost segregation study.
The short-term rental classification removes the automatic passive character, self-management establishes material participation, and the study produces a large first-year deduction that is consequently non-passive and available against business income.
The requirements are specific and all of them matter: the average stay must be seven days or less measured across the year, the owner must materially participate with contemporaneous records, and full-service management generally defeats the participation test. Each condition is where these positions fail on examination.
The Limits That Still Apply
Even where the passive problem is solved, two limits remain.
The excess business loss limitation caps how much net business loss can offset non-business income in a year, with the excess carried forward. On very large studies this can spread the benefit across several years even when everything else is correct.
Basis and at-risk rules limit deductions to the amount the owner has invested and is economically at risk for. This is where entity structure matters: partnership rules include a share of entity debt in basis, while S-corp shareholders receive no basis from entity borrowings. Holding leveraged real estate in an S-corp routinely suspends losses for lack of basis, which is a structural error rather than a tax one.
Where the 1031 Exchange Fits
A like-kind exchange under Section 1031 defers gain on the sale of investment or business real property when the proceeds are reinvested in replacement property within the statutory timeframes: 45 days to identify replacement property and 180 days to close.
For a business owner, the exchange serves a different purpose from the strategies above. Cost segregation accelerates deductions against current income; a 1031 exchange defers the tax that would otherwise arrive on a sale, including the depreciation recapture that a cost segregation study makes larger. The two are complements rather than alternatives, and they interact directly: an owner who has taken large accelerated depreciation has more recapture exposure on sale, which strengthens the case for exchanging rather than selling outright.
The constraints are real. The property must be held for investment or productive use in a trade or business, so a personal residence does not qualify and a property held primarily for resale does not either. The timeframes are strict and are not extended for ordinary difficulties in finding replacement property. And the proceeds must not be constructively received by the seller, which is why a qualified intermediary is engaged before closing rather than after.
Sequencing a Real Estate Strategy
The order in which these decisions are made determines how much of the benefit survives.
First, establish which route through the passive rules is available, because it determines whether any deduction is worth generating. Second, settle the holding structure, since entity choice governs whether debt creates basis and whether the property can be moved later without triggering gain. Third, make and document any grouping or aggregation election, because these are difficult to change once made. Only then commission the cost segregation study, and time it against the year with the most income to offset.
Owners commonly run this in reverse: they buy a property, have a study done because it was offered, and then discover the loss is suspended and the structure is wrong. Every element of that sequence is recoverable, but the recovery costs more than the planning would have.
The Augusta Rule, Briefly
Section 280A(g) permits renting a personal residence for up to fourteen days a year without the rental income being taxable. A business owner with an entity can have the business rent their home for legitimate meetings, producing a deduction to the business and untaxed income personally.
It is legitimate and it is modest in scale relative to the strategies above. It requires genuine business use, contemporaneous documentation of what actually occurred at each meeting, and a rate supported by comparable local venue pricing. Undocumented use of it does not survive examination.
The practical value is in treating it as one small, clean item within a larger plan rather than as a strategy in its own right. Owners who build a plan around it are usually being sold something; owners who add it to a plan already containing structure, plan design, and depreciation are simply collecting a provision that applies to them.
Key Takeaways
- Passive activity rules, not the size of the deduction, decide whether a study is worth commissioning.
- Property used in your own business is the cleanest route, and the grouping election makes it work.
- Short-term rentals with an average stay of seven days or less are not rental activities under Section 469.
- REPS is generally unreachable for a busy owner but reachable through a qualifying spouse.
- Self-managed short-term rental plus cost segregation is the most common effective combination.
- Excess business loss and basis limits still apply even after the passive problem is solved.

Frequently Asked Questions
Can I use real estate losses to offset my business income?
Only through one of four routes: the property is used in your own trade or business, it is a short-term rental averaging seven days or less per stay where you materially participate, you or your spouse qualify as a real estate professional, or you have passive income for the losses to offset. Otherwise the losses are suspended and carried forward.
What is the short-term rental loophole?
An activity where the average period of customer use is seven days or less is not a rental activity under the Section 469 regulations, so it escapes automatic passive classification. The owner then needs only to materially participate, not to qualify as a real estate professional, for the losses to be non-passive.
Do I need real estate professional status?
Not for the short-term rental route or for property used in your own business. REPS matters for conventional long-term rentals, and a business owner working full time in their company generally cannot meet the more-than-half test. A qualifying spouse is the usual route, since the tests are applied per spouse.
How much depreciation does cost segregation produce?
Typically 20 to 35 percent of depreciable basis for commercial property and 15 to 25 percent for residential rental, all immediately deductible under permanent 100 percent bonus depreciation. On $1,500,000 of basis that is roughly $300,000 to $450,000 in the first year.
What if I already have suspended passive losses?
They carry forward indefinitely and are freed when you have passive income, when the activity's classification changes, or when the property is sold in a fully taxable transaction. Acquiring passive income producing investments is a legitimate way to use a large suspended balance.
Does a property manager affect my ability to use losses?
Substantially, on the short-term rental route. Material participation requires your own hours, and a full-service manager handling bookings, cleaning, and maintenance means those hours belong to them. Self-management is usually necessary for that strategy to work.
Should real estate be held in my S-corp?
Generally no. S-corp shareholders receive no basis from entity-level debt, which suspends the very losses the property is held to generate, and distributing appreciated property out of a corporation triggers gain as though it were sold. A partnership or disregarded LLC is nearly always the correct holding structure.
