Every month you write a rent check to a landlord. Nothing wrong with that, until the day it occurs to you that you could be writing it to yourself.
That is the idea behind self-rental. You buy the building your business operates out of, hold it in a separate entity, and lease it back to your own company. The business deducts the rent, the same as it always did. The difference is where the money lands. Instead of building your landlord’s equity, it builds yours.
The tax code has opinions about this, because you are now sitting on both sides of a lease. You set the rent, you sign both copies, and the IRS has watched enough people abuse that arrangement to write specific rules for it.
Those rules are stranger than most owners expect. Rental income is passive by default, and passive income is useful, because it can absorb passive losses sitting suspended on your return. But self-rental income gets recharacterized as non-passive, so it cannot do that job. Meanwhile self-rental losses stay passive and get trapped. Income that cannot help you, losses that cannot help you either. There is a fix, called a grouping election, and almost nobody tells you what it costs.
Here is the part that matters more than any of it. If you buy a cost segregation study expecting a big first-year deduction against your business income, the self-rental rule may suspend the whole thing. If you make a grouping election to free it up, you may have complicated the exit you actually wanted, which is selling the business in fifteen years and keeping the building.
That exit is the real reason to do this. The deduction is a nice year-one story. The building is the thing that outlives the company.
So this is the whole picture. What the self-rental rule does, how the grouping election works and what it permanently costs you, how to set a rent that holds up, the QBI angle almost nobody mentions, and the honest answer to whether you should buy the building at all.
What qualifies as a self-rental?
A self-rental is any arrangement where you own rental property and lease it to a trade or business in which you materially participate. The classic version is a business owner who owns the building personally or through an LLC and rents it to their own operating company. The IRS cares about this arrangement specifically because you sit on both sides of the lease, which means you control the rent, and controlling the rent means you could otherwise manufacture whatever tax result you wanted.
A self-rental is when you own a piece of property in one entity and rent it to another entity you also own.
For example, you operate your business out of one entity and you own the commercial real estate that business occupies in a separate entity. If you materially participate in the operating business, that is a self-rental. You are on both sides of the transaction.
The rule itself lives in Reg. §1.469-2(f)(6), which applies when property is “rented for use in a trade or business in which the taxpayer materially participates.” Two conditions, and both have to be true. The property is rented to a business, and you materially participate in that business.
That second condition is the one people skim past. Material participation is a defined term with seven tests under Reg. §1.469-5T, and most owner-operators clear the first one without thinking about it: more than 500 hours in the activity during the year. If you run the business day to day, you materially participate. If you are a genuinely passive investor in the operating company, you do not, and the self-rental rule does not apply to you at all.
That distinction matters more than it sounds like it should. Two people can own the exact same building, rent it to the exact same business, and get completely different tax treatment based only on whether they work there.
You also need two separate entities. An operating S-corp and a separate LLC holding the real estate is the common setup. A sole proprietor who operates the business and owns the building personally does not qualify, because that is not two entities transacting. That is one taxpayer, and the rent would be a deduction and income on the same return, canceling to nothing. Same trap that keeps a sole proprietor from using the Augusta Rule.
When you are on both sides of a transaction, the IRS writes special rules to make sure you are not manufacturing a result that would not exist between strangers. That is the whole reason this section of the code exists.
Most owners land on a separate entity for the real estate anyway, for reasons that have nothing to do with taxes. It limits liability, it keeps the building off the operating company’s balance sheet, and it means you can sell the business one day and keep the property. The tax rules are just what you inherit once the structure is in place.
Is self-rental income considered passive?
No, and that is the trap. Under the self-rental rule, net rental income from property you lease to a business in which you materially participate is recharacterized as non-passive. Net rental losses, however, stay passive. The asymmetry runs one direction only. You cannot use self-rental income to absorb passive losses from your other investments, but if the rental generates a loss, that loss is suspended as passive until you have passive income or you dispose of the activity.
Rental real estate is passive by default. That is the starting point, and it is why the rest of this is strange.
Passive is not a bad word in tax. Passive income is genuinely useful, because passive losses can only offset passive income. If you have suspended passive losses sitting on your return from a rental property or an old partnership interest, you need passive income to free them up. That is the whole point of the bucket.
Reg. §1.469-2(f)(6) takes self-rental income out of that bucket. Net rental income from property you lease to a business in which you materially participate is recharacterized as non-passive. It cannot absorb your suspended passive losses, because it is no longer passive income.
The losses, though, stay passive.
Read those two sentences together, because that is the entire trap. Income is non-passive. Losses are passive. The rule runs one direction only, and it is not your direction. If the building throws off income, that income cannot help your passive losses. If the building throws off a loss, that loss cannot help your business income. It sits suspended until you have other passive income or you dispose of the property.
Here is what that looks like with numbers.
Say you own a commercial building through an LLC and lease it to your operating company for $200,000 a year. After mortgage interest, property taxes, insurance, and depreciation, the building nets $60,000 of income. You also have $150,000 of suspended passive losses from a rental you bought years ago that has never quite worked.
Your instinct is that the $60,000 of building income absorbs $60,000 of those suspended losses. It does not. The $60,000 is non-passive under the self-rental rule, so it lands on your return as income with nothing to offset it. Your $150,000 of suspended losses is exactly where it was on January 1.
Now flip it. Same building, but you run a cost segregation study and generate $400,000 of accelerated depreciation. Now the building shows a $340,000 loss. Surely that offsets some of your operating income.
It does not. That loss is passive, your business income is non-passive, and passive losses cannot offset non-passive income. The $340,000 sits suspended. You paid for a cost segregation study and got a deduction you cannot use this year.
Both directions, the answer is no. That is not an accident, and understanding why makes the rest of this post easier.
Before the rule existed, the arrangement worked beautifully in one direction. An owner would rent property to their own business at a generous rent, generate rental income that was passive by default, and use that manufactured passive income to absorb suspended passive losses from unrelated tax shelters. The income was not really passive in any economic sense. You controlled the rent, so you could dial up exactly as much passive income as you needed to soak up whatever losses you were carrying.
These arrangements had a name. Practitioners called them passive income generators, or PIGs. You bought or created one specifically to feed the losses you already had.
Treasury closed the door by recharacterizing self-rental income as non-passive, which removed the only thing PIGs were useful for. The asymmetry that feels arbitrary when you first meet it is actually the point. The rule was written to stop one specific abuse, and it stops it by making sure self-rental income can never perform that function again.
Which leaves the loss side. There is exactly one way to free those suspended losses and use them against your business income, and that is a grouping election.
What is the self-rental grouping election?
A grouping election under the passive activity rules lets you treat your rental activity and your operating business as a single activity, if they form what the regulations call an appropriate economic unit. Grouped together, losses from the rental can offset income from the business, which solves the asymmetry. The requirements include common ownership in the same proportions, the business being the primary user of the property, and your material participation. What almost nobody mentions is that the election is generally irreversible and it changes what happens when you sell.
Most business owners buy commercial real estate and run a cost segregation study on it to accelerate depreciation. Then they find out at filing time that under the self-rental rules, those losses do nothing against their business income.
There is one way to free them up, and it is to tell the IRS you want the two businesses treated as a single activity. That is a grouping election under Reg. §1.469-4(c)(1).
The concept is straightforward. Passive losses cannot offset non-passive income, but if the rental and the operating business are one activity rather than two, there is nothing to cross. The loss and the income live in the same bucket, and they simply net.
A medical practice generates $900,000 of taxable income flowing through its S-corp. The owner decides to stop renting and buy the building, purchasing a $3,000,000 commercial property through a separate LLC that she owns 100%. She runs a cost segregation study, which produces $900,000 of accelerated depreciation in year one. The operating company pays the LLC $20,000 a month in rent, so $240,000 for the year.
Without a grouping election, here is where everything lands.
The S-corp deducts the rent it paid, so $900,000 of income minus $240,000 of rent leaves $660,000 flowing to her return as non-passive business income.
The LLC collects $240,000 of rent and claims $900,000 of depreciation, so it shows a $660,000 loss. That loss is passive. It cannot touch the $660,000 of business income sitting right next to it on the same return. It suspends.
She has $660,000 of taxable income and a $660,000 loss she is not allowed to use.
With a grouping election, the two are one activity.
$660,000 of business income, less the $660,000 loss from the building, is zero taxable income flowing to her return.
At a 30% effective rate, that is roughly $198,000 of tax she does not pay this year. She put $600,000 down on the building. Net of the tax savings, her cash outlay in year one was about $402,000 for a $3,000,000 property her practice now controls, in a building she will still own long after she sells the practice.
Same facts. Same building. Same study. One election.
The activities have to form an appropriate economic unit. That is the standard in Reg. §1.469-4, and the regulation lists factors: similarities in the types of business, common control, common ownership, geographic location, and interdependence between the activities.
A building your business occupies and the business occupying it are about as interdependent as two activities get. That is the easy case. A building your business does not use, sitting across the state, grouped with your operating company because you happen to own both, is not one economic unit and grouping it would not hold.
Ownership and control have to line up. Under Reg. §1.469-4(d)(1), a rental activity generally cannot be grouped with a trade or business unless the ownership is proportionate. This is where real arrangements fail.
If your brother owns the operating business and you own the building, those are two separate businesses with separate owners. No grouping.
If you and your brother are 50/50 in both entities, you are proportionate, so far so good. But if you are a passive investor in the operating company while he runs it, you have a different problem. You do not materially participate, which means the self-rental rule never applied to you in the first place, and grouping cannot give you a benefit you were never in position to receive.
You have to file the election. Under Rev. Proc. 2010-13, you attach a written statement to your return by the due date including extensions. The statement names the activities being grouped, with addresses and EINs, and declares that they constitute an appropriate economic unit for measuring gain or loss under §469.
That statement is the whole election. There is no form, no approval, and nobody sends you a confirmation. Which means it is also easy to simply never file, and a grouping you meant to make but never disclosed is not a grouping.
Here is the part that gets left out of every article that ends at “make the grouping election.”
It is effectively permanent. Once you group, you cannot ungroup because your situation changed and a different answer would now be better. Regrouping is allowed only in narrow circumstances, essentially where the original grouping was clearly inappropriate or where a material change in facts makes it clearly inappropriate. Wanting a better tax outcome is not a material change in facts.
And it changes what happens when you sell. This is the consequence almost nobody surfaces, and it collides directly with the reason most owners buy the building.
Suspended passive losses are released when you dispose of the entire activity. If you have grouped the building and the business into one activity, the activity is both of them. Selling one piece is a partial disposition, and a partial disposition does not release the suspended losses.
Picture two long-term rentals you have grouped together. Both run at a loss, and you are accumulating suspended losses across the group. You sell one property expecting the suspended losses to free up. They do not, because you disposed of half an activity. The losses stay put until the second property goes.
Now apply that to the exit this post keeps pointing at. You group the building with the practice to unlock a cost segregation deduction in year one. Fifteen years later you sell the practice and keep the building, which was the plan the whole time. You have disposed of part of a grouped activity, not all of it, and any suspended losses riding along stay suspended.
That is not an argument against grouping. For an owner with a large cost segregation deduction and a business that will use the building for the next twenty years, grouping is usually the right call, and the year-one savings are real. It is an argument for making the election with your exit in view instead of making it to solve one tax year and discovering the constraint a decade later.
Should you buy the building your business operates in?
It depends on four things: whether your business is stable enough to commit to the location for a decade or more, whether the capital would earn more inside the business than in the building, whether you can carry the mortgage if the business has a bad year, and whether you are comfortable concentrating your business and your largest asset in the same bet. When those line up, owning the building is one of the better wealth decisions an owner can make, because the building outlives the business.
There are a lot of good reasons for your business to own the building it occupies. There are also plenty of reasons this is the wrong year to do it.
Start with the fact that you are already paying rent. That money leaves your business every month no matter what. The only question is whose balance sheet it builds. If you can find a property where the loan payment lands somewhere near your current rent, you have essentially redirected an expense you were paying anyway into equity you keep.
That is the whole case in one sentence, and it is a good one. Here is everything that complicates it.
Renting does not build wealth, but it buys optionality. You can move, take more space, take less, or leave the market entirely when the lease ends. Buying is a statement that this is where you plan to be for the next ten to twenty years.
Look at all the office space that sat empty during and after Covid. Every one of those buildings belonged to somebody who was confident about the next decade.
How much that costs you depends on your business. A manufacturer worries mostly about outgrowing the facility, which is a solvable and fairly predictable problem. A retail business lives and dies on the location itself, and a neighborhood can change underneath you in ways no lease term protects against. Ask honestly which one you are.
Rent is deductible either way. When you own the building, that same deductible rent is covering your mortgage, taxes, and insurance while you build equity, and a cost segregation study can put depreciation to work sheltering the rental income. Done right, the building is cash-flow positive and shows a tax loss at the same time.
Then there is the down payment, which is where a lot of these deals actually get decided. Commercial financing usually wants 20% to 30% down, though SBA 504 exists specifically for owner-occupied commercial property and typically requires meaningfully less, often around 10%.
The money usually comes out of business profits, which raises the real question. Would that capital do more inside the business? If you are scaling, and a dollar in the business reliably returns three, then parking it in a down payment is an expensive way to buy stability. Real estate appreciates at a rate a growing company should be embarrassed by. If growth has flattened and the cash is just accumulating, that math flips completely.
Owning means no landlord. Renovate as you like, no renewal negotiation, nobody raising your rent because the market moved, nobody declining to renew because they have a better use for the space.
It also means you are the landlord. Maintenance, property taxes, insurance, and every repair are now yours. If the roof goes, that is your problem and your capital. For a busy owner, that is real time and real attention pulled away from the business that actually generates your income.
This is the one to sit with. Buy the building and your income, your business, and your largest single asset all become the same bet, in the same location, exposed to the same local economy. If the business struggles, it usually struggles for reasons that also hurt the building’s value and your ability to re-lease it.
And you are signing personally. Commercial mortgages for small businesses almost always come with a personal guarantee, which means a failed business can leave you owning an empty building with a loan you still owe on it.
Everything above is the case for caution. Here is the case that outweighs it for the right owner, and it has almost nothing to do with this year’s deduction.
You can sell the business and keep the building.
Think about what that means. You spend twenty years building a company, you sell it, and the buyer needs somewhere to operate. They become your tenant. The building keeps paying you every month after you have stopped working, from a business you no longer own. Or you 1031 into something passive and never take a maintenance call again. Or you hold it, let it appreciate, and let your heirs take it with a stepped-up basis.
The deduction is a year-one story. The building is a thirty-year one.
Most owners never consider this until the sale is already being structured, at which point the building is tangled up in the deal and separating it is expensive or impossible. The time to decide you want to keep the building is before you buy it, not while a buyer’s attorney is drafting an asset purchase agreement.
How much rent should you charge your own business?
Fair market rent for comparable commercial space in your area, documented the same way you would document any related-party transaction. Charge above market and the IRS can recharacterize the excess as a distribution or disguised compensation, which costs you the deduction and can create a second problem on the owner side. Charge below market and you are leaving a deduction on the table for no reason. Pull real comparables, write an actual lease, and keep the file.
Any time you are on both sides of a transaction, everything has to be at arm’s length. That means acting as though the two parties are strangers, because for tax purposes, that is the standard you will be measured against.
The rent can fail in both directions.
Charge above market and you are moving income out of the operating business into the real estate entity, where losses can absorb it. The IRS can recharacterize the excess, and depending on the facts it becomes a distribution or disguised compensation rather than deductible rent. You lose the deduction on the business side, and you may create a second problem on your side.
Charge below market and you have simply left deductions on the table. The rent is lower, so the business deducts less, and you have wasted part of the structure you built.
Given the choice, err low. The IRS does not send letters demanding you take larger deductions. Your loss is their gain, and they are content to let you make it.
We see the same pattern constantly: a building set up to zero out. Real estate expenses run $20,000 a month, so the rent is set at exactly $20,000, even though comparable space in that market leases for $15,000. It is a tidy number and it is completely indefensible, because nobody arrived at it by looking at the market. They arrived at it by looking at their own expenses.
That is the thing an examiner notices. A rent that exactly matches your costs is evidence you set the rent from the inside out.
Multi-Pak Corp. v. Commissioner (T.C. Memo. 2010-139) is a compensation case rather than a rent case, but the reasoning transfers directly, and it is the same analysis an examiner applies here. The question the court asks about any related-party payment is what an independent party would have paid under the same circumstances. Not what was convenient. Not what produced the best tax result. What the market would have borne.
That standard is not difficult to meet. It just requires you to have done the work before anyone asks.
Start with comparables for like-kind commercial space in your market. Two questions frame it. What would your business pay to lease this space from an unrelated landlord? What would you charge an unrelated tenant to lease it from you?
Pull real listings. Commercial brokerage sites, local listings, and any lease you or your landlord already have. Look for:
Build a file. Screenshot the listings, date them, note the source, and write down how you reasoned from the comparables to your number. If you land at $18 per square foot because four comparable properties run $16 to $20 and yours is newer than two of them, write that sentence down. That sentence is the whole defense.
If this feels familiar, it should. It is the same discipline as substantiating an Augusta Rule rate, and the reason is identical. In a related-party transaction, the number is only as good as the file behind it.
Revisit the file every couple of years and adjust the rent to keep pace with the market. Setting it once and never touching it is how owners drift below market and quietly overpay tax for a decade.
This is not a handshake with yourself and a transfer whenever you remember. Draft a real lease between the real estate entity and the operating company, covering:
If you currently lease space from someone else, pull that lease out and read it. Yours should look substantially similar. Then pay the rent on schedule, from the operating account to the real estate entity’s account, on the terms the lease actually says. A lease that says the first of the month and a payment that shows up in irregular lumps in December is worse than no lease, because now the document contradicts you.
Self-dealing is not a reason to be loose with the paperwork. It is the reason to be stricter than you would be with a stranger, because with a stranger the arm’s-length nature of the deal is self-evident. Here, you are the only one who can prove it.
A lot of owners buy more space than they currently need and lease the rest to unrelated tenants. That works, and it changes the accounting.
The portion leased to your own business follows the self-rental rules, with income recharacterized as non-passive. The portion leased to third parties is ordinary rental activity and stays passive under the normal rules.
That means allocating between the two, usually by square footage, and tracking them separately. It also means your building can produce non-passive income and passive income at the same time, from the same property, in the same year. Your bookkeeping has to be able to tell the difference, because your return has to.
Does self-rental income qualify for the QBI deduction?
It can. Under the §199A regulations, rental to a trade or business under common control is treated as a trade or business for QBI purposes, which means the rental income may qualify for the 20% qualified business income deduction. Common control generally means the same person or group owns at least 50% of both the rental and the operating business. For an owner already collecting rent from their own company, this can be a meaningful additional benefit that never shows up in the articles about the self-rental rule.
Here is a benefit that almost never comes up in articles about the self-rental rule, largely because it lives in a completely different part of the code.
Rental real estate does not automatically qualify for the Qualified Business Income deduction. QBI requires a trade or business, and a passive rental often does not rise to that level. That is why so many landlords miss the deduction entirely.
Self-rental is different. Under Reg. §1.199A-1(b)(14), rental to a trade or business under common control is treated as a trade or business for QBI purposes. Common control generally means the same person or group owns at least 50% of both the rental entity and the operating business. If you own both, you clear that easily.
So the rent your business pays you may qualify for the 20% qualified business income deduction on your side. On $200,000 of rental income, that is potentially a $40,000 deduction that a landlord renting to a stranger would have to fight for.
These are two different questions with two different tests, and owners conflate them constantly.
Whether your income is passive or non-passive is a §469 question, answered by material participation. Whether your rental is a trade or business for QBI is a §199A question, answered by common control. Passing one test tells you nothing about the other.
They happen to point the same direction for most self-rental owners, which is why the confusion rarely causes harm. But they are separate analyses and they can diverge, so do not assume that clearing one clears the other.
This is where it gets uncomfortable for a lot of the owners most likely to buy their building.
Under the §199A regulations, when you rent to a commonly controlled business that is a specified service trade or business, the rental gets treated as an SSTB too, to the extent of that related-party rental. The character of the operating business flows through to the building.
So if you are a physician, a dentist, an attorney, an accountant, or a financial advisor, your operating business is an SSTB, and your building becomes one by association. That matters because SSTBs lose the QBI deduction entirely above the income phaseout thresholds, and the owners buying commercial buildings are frequently above those thresholds.
Which produces a genuinely counterintuitive result. A physician earning $600,000 who buys her own building gets no QBI deduction on the rent, because the rental inherits her SSTB status and she is over the threshold. A manufacturer earning the same $600,000 in the same building gets the deduction, because manufacturing is not an SSTB.
Same building. Same rent. Same structure. Different professions, different answer.
There is a meaningful carve-out. The SSTB taint applies to the portion rented to the commonly controlled SSTB. A portion rented to unrelated third parties is evaluated on its own.
Take the physician above. She buys a building, uses 60% for her practice, and leases the other 40% to an unrelated insurance agency. The 60% rented to her practice inherits SSTB status and is likely phased out at her income level. The 40% leased to the insurance agency is not connected to her SSTB, and that rental income may still qualify for the deduction on its own merits.
For a high-income service professional, that changes how you think about how much building to buy. Extra space leased to unrelated tenants is not just additional rent. It can be the only part of the building producing a QBI deduction at all.
What are the most common self-rental mistakes?
Five: expecting self-rental income to absorb passive losses when it has been recharacterized as non-passive, running a cost segregation study without a grouping election and watching the loss get suspended, making a grouping election without understanding it is close to permanent, charging a rent nobody documented, and holding the building in a structure that makes it expensive to ever get out. Each one is fixable in advance and expensive to fix afterward.
This is the most common misunderstanding, and it is understandable, because the rule was written specifically to stop it.
Owners carrying suspended passive losses from an old rental or a partnership interest go looking for passive income to free them up. Buying the building your business already occupies looks like the perfect solution. Rental income is passive, you need passive income, and you were paying the rent anyway.
Then the self-rental rule recharacterizes that income as non-passive and it cannot do the one job you bought it for. The losses stay exactly where they were.
The cost is not a penalty. It is a plan built on an outcome that was never available, usually discovered at filing, after the building is bought and the closing costs are spent.
A cost segregation study takes a building that would depreciate over 39 years and reclassifies the components into 5, 7, and 15-year lives, which unlocks accelerated depreciation and can generate a very large first-year deduction.
The study works exactly as advertised. The problem is where the deduction lands. Without a grouping election, that loss is passive, your business income is non-passive, and the two never touch. You paid five figures for a study that produced a suspended loss.
Cost segregation firms rank near the top of search results for the self-rental rule for exactly this reason. The study is not the mistake. Running it without knowing whether you qualify to group is.
Make the grouping decision before you commission the study, not after you see the number.
For most owners with a building their business occupies, grouping is the right call. It unlocks the deduction and the year-one savings are real.
The mistake is treating it as a checkbox on this year’s return rather than a structural decision. You cannot ungroup later because your situation changed and a different answer would now be better. Regrouping is available only in narrow circumstances, and wanting a better tax result is not one of them.
The cost shows up years later, at the exit. Group the building with the business, then sell the business and keep the building, and you have disposed of part of an activity rather than all of it. Suspended losses riding along stay suspended.
Decide with your exit in view. The election is cheap to make and expensive to regret.
Any time you are self-dealing, the standard is arm’s length. The rent has to be what an unrelated party would have paid.
The failure is almost always the same. The number gets picked from the inside out, chosen because it zeroes out the rental income, or maximizes the deduction on the operating side, or simply matches the mortgage payment. Nobody looked at what comparable space in the market actually leases for.
Above market, the IRS can recharacterize the excess as a distribution or disguised compensation, which costs you the deduction and can create a problem on your personal side. Below market, you have quietly overpaid tax for as long as it has been running.
Pull comparables, write down how you reasoned from them to your number, sign a real lease, and pay it on the terms the lease states. Then revisit the file every couple of years, because a rate that was defensible in 2020 may not be defensible now.
Almost everything in this article depends on a structure you set up before any of it applies.
You need two genuinely separate entities. A sole proprietor who owns the building personally has nothing to work with, because there is no second taxpayer to pay rent to. And the ownership across the two entities has to line up, or grouping is off the table regardless of how well the rest of the arrangement is documented.
Which entity holds the real estate is the decision with the longest tail. Some structures make it straightforward to refinance, add a partner, or eventually take the property out. Others make getting the building back out expensive or effectively impossible, and by the time that becomes a problem, the property has usually appreciated enough that fixing it is the most expensive option on the table.
When should I talk to an advisor about self-rental?
Before you buy the building, because the structure and the grouping decision are both much easier to get right than to fix. Also worth a conversation if you already rent to your own business and have never looked at whether the rent is defensible, whether a grouping election helps or hurts your eventual exit, or whether the rental income qualifies for the QBI deduction. This is a decision with a twenty-year horizon, and most of the expensive mistakes happen in the first ninety days.
Here is what makes this one different from most tax strategies.
The Augusta Rule is a small deduction you can run yourself and unwind next year if you change your mind. Self-rental is not that. You are buying a building, choosing a structure, and possibly making an election you cannot take back, all in the same few months. The decisions cluster at the front, and almost none of them are cheap to reverse.
That is the argument for having someone look at it before you close rather than after. Not because the rules are impossible to understand, but because the expensive mistakes here are structural, and structural mistakes are the ones you live with for twenty years.
The other reason is that this sits in two places at once. Your CPA can tell you what the self-rental rule does. Your realtor can tell you what the building is worth. Neither one is usually asking whether the capital would do more inside the business, or what happens to the property when you sell the company, or whether the grouping election that saves you money this year quietly complicates the exit you actually want. Those are the questions that determine whether this works out, and they sit between tax and wealth rather than in either one.
We do that work under one roof, which is the whole reason to have this conversation before the wire hits, not after.
If any of these sound like you, it is worth a conversation:
Triggers:
Find out whether owning your building actually makes sense for you. Book a 30-minute discovery call
The self-rental rule is one of the stranger corners of the tax code. Income you cannot use, losses you cannot use, and a fix that costs you something on the far end. It is worth understanding, and it is not the reason to do this.
The reason is simpler than any of it. You are already paying rent. That money leaves your business every month regardless. Owning the building only changes where it lands, and the change compounds for as long as you own the place.
Get the front end right, because that is where this is decided. Two separate entities. A rent you can defend with a file behind it. A real lease you actually follow. A grouping decision made with your exit in view instead of just this year’s return.
Then let it run. And in fifteen or twenty years, when you sell the company and the new owner writes you a rent check every month for a building you still own, that will have almost nothing to do with a deduction and everything to do with a decision you made now.
A self-rental is any arrangement where you own rental property and lease it to a trade or business in which you materially participate. The most common version is a business owner who owns the building personally or through an LLC and rents it to their own operating company. The IRS treats it as a special case because you control both sides of the lease, which means you control the rent.
No. Under the self-rental rule, net rental income from property leased to a business in which you materially participate is recharacterized as non-passive. The asymmetry is that net rental losses stay passive. So you cannot use self-rental income to absorb passive losses from other investments, but a loss from the rental gets suspended until you have passive income or dispose of the activity. A grouping election can address this, with tradeoffs.
The core rule recharacterizes net self-rental income as non-passive while leaving net losses passive. Beyond that, the rent must be fair market value for comparable space, the arrangement should be documented with a real written lease, and the building generally has to be held in an entity separate from the operating business for the structure to work. If you want rental losses to offset business income, you need a grouping election, which carries its own long-term consequences.
Not in any way that produces a deduction. If you operate as a sole proprietor and own the building personally, there is no separate taxpayer to pay rent to. The rent would be a deduction and income on the same return and would simply cancel. This is the same trap that keeps sole proprietors from using the Augusta Rule. You need a separate operating entity for the arrangement to do anything.
It depends on four things: whether the business is stable enough to commit to the location for a decade or more, whether the capital would earn more inside the business, whether you can carry the mortgage through a bad year, and whether you are comfortable concentrating your business and your largest asset in the same bet. When those line up, it is one of the better wealth decisions an owner can make, largely because you can eventually sell the business and keep the building.
