Self-Rental Rule: Renting Property to Your Own Business
The self-rental rule says that if you rent a building to a business you materially participate in, the net rent is nonpassive income, not passive. It comes from Reg. §1.469-2(f)(6). The result is lopsided: the income cannot soak up passive losses from your other rentals or syndication K-1s, but a loss on the same building stays passive. And the rule follows the building to the closing table, so the gain on sale is nonpassive too.
This matters most to the people who own their own buildings: the dentist or physician group with a medical office building, the contractor with a yard and shop, the family manufacturer with the plant in a separate LLC.
The rule in the regulation's own words
Reg. §1.469-2(f)(6) reads:
The regulation, lightly paraphrased: An amount of the taxpayer's gross rental activity income for the taxable year from an item of property equal to the net rental activity income for the year from that item of property is treated as not from a passive activity if the property (i) Is rented for use in a trade or business activity ... in which the taxpayer materially participates (within the meaning of § 1.469-5T) for the taxable year".
Three things to notice:
- It is property by property. The test runs on "an item of property," not on all your rentals together.
- It only touches net income. The amount recharacterized equals the net rental activity income. If the building shows a net loss, nothing is recharacterized and the loss stays passive.
- It turns on material participation in the business, measured under the seven tests in Temp. Reg. §1.469-5T (see material participation for rentals). A physician who works full time in her practice easily materially participates in it.
Why the rule exists, and why it stings
Before the rule, an owner could charge his own company high rent, create "passive" income in the building LLC, and use it to absorb passive losses from tax shelters. The self-rental rule shuts that down. The rent is still deductible to the business (reducing nonpassive business income) and taxable to you, but it lands in the nonpassive bucket.
The sting is the asymmetry. Income in, it's nonpassive. Loss out, it's passive. For a newer building with heavy depreciation, the early years may show losses that get stuck on Form 8582, and the later profitable years only recharacterize the building's net income, so its own old losses net first and nothing else passive can use the rent.
| Self-rented building shows | Treatment |
|---|---|
| Net income | Nonpassive (Reg. §1.469-2(f)(6)) |
| Net loss | Passive; limited by §469 like any rental loss |
| Gain on sale (rented within 12 months of sale) | Recharacterized as nonpassive (Reg. §1.469-2(f)(9)(iii)) |
A simple example: the medical office building
Simple example (2026 married filing jointly, federal only). Dr. Lee's practice pays her building LLC rent that produces $60,000 of net rental income. She also owns a passive duplex that throws off a $40,000 loss each year from depreciation. Her other taxable income, after deductions, is $500,000.
- If the building rent were passive, the $40,000 duplex loss would offset it. Taxable income: $520,000. Federal tax: $119,538.
- Under the self-rental rule, the $60,000 is nonpassive and the duplex loss is suspended. Taxable income: $560,000. Federal tax: $133,538.
The rule costs her $14,000 of federal tax this year, all at the 35% bracket, and the $40,000 joins her pile of suspended losses. (Computed with the 2026 brackets from Rev. Proc. 2025-32.)
The rule reaches the sale
Many owners assume the sale is where the stuck losses finally get used. For a self-rented building, it is not.
Reg. §1.469-2(f)(9)(iii) defines gross rental activity income to include income "from the rental or disposition of such item of property," and, for a disposition, income "from an activity that involved the rental of such item of property during the 12-month period ending on the date of the disposition." So if the practice was your tenant in the last 12 months, the net gain on the building gets the same nonpassive label.
What that means in practice:
- The gain on the medical office building will not absorb suspended losses from your duplex, your LP interests or other syndications.
- Losses from the building itself are a different story. If you sell your entire interest in that activity to an unrelated buyer in a fully taxable sale, §469(g) releases that activity's own suspended losses (see suspended passive losses when you sell).
- An installment sale does not change the character. The waterfall idea of spreading passive gain to meet passive losses simply does not apply here, which is one of the cases in when an installment sale won't help passive losses.
Spreading the gain over years can still help with brackets, NIIT and state tax. It just cannot unlock unrelated passive losses.
Grouping: the planning lever, with conditions
Reg. §1.469-4 lets you treat activities as one if they form "an appropriate economic unit for the measurement of gain or loss." But a rental cannot be grouped with a business unless, under Reg. §1.469-4(d)(1)(i), it also meets one of three conditions:
The regulation, lightly paraphrased: (A) The rental activity is insubstantial in relation to the trade or business activity; (B) The trade or business activity is insubstantial in relation to the rental activity; or (C) Each owner of the trade or business activity has the same proportionate ownership interest in the rental activity, in which case the portion of the rental activity that involves the rental of items of property for use in the trade or business activity may be grouped with the trade or business activity.
When grouping is available, the rent and the business are one activity, so the rental is no longer a separate passive activity. That can matter for a building that runs at a loss. But grouping has two costs worth weighing:
- It is sticky. Under Reg. §1.469-4(e)(1), once you group activities "the taxpayer may not regroup those activities in subsequent taxable years," except when the grouping becomes clearly inappropriate or facts change materially.
- It changes what a "disposition" is. Selling only the building out of a grouped activity is not a sale of your entire interest in the activity, so §469(g) may not release losses until you dispose of substantially all of it (Reg. §1.469-4(g)).
The same "one activity" logic shows up in the aggregation election for real estate professionals.
Common fact patterns
| Owner | Tenant | Material participation in tenant? | Result |
|---|---|---|---|
| Surgeon | Her own surgical practice | Yes | Net rent and sale gain nonpassive |
| Retired founder | Business he no longer works in | Tested each year; may fail | Rent may be passive again, but see the 24-month rule below |
| Silent LLC investor | Operating company he does not work in | No | Ordinary passive rental |
| Contractor | His construction company | Yes | Net rent and sale gain nonpassive |
One more trap for sellers who stop working. Even after you retire from the business, Reg. §1.469-2(c)(2)(iii) treats gain on substantially appreciated property as nonpassive unless the property was used in a passive activity for 20% of your holding period or for the entire 24 months before the contract. We walk through that clock in retired real estate professional.
Bottom line
If your business is your tenant, the building's net income and its sale gain are nonpassive under Reg. §1.469-2(f)(6) and (f)(9)(iii). They will not free up unrelated passive losses, while the building's own losses stay passive. Grouping can help in narrow cases and is hard to undo. If you are counting on a building sale to use up stuck losses, check the tenant first. The free book shows which sellers the loss-matching idea fits and which it does not.
Questions to ask your CPA
- Is any property I own rented to a business in which I materially participate this year, or was it in the 12 months before a planned sale?
- How much of my suspended loss on Form 8582 belongs to the self-rented building versus my other activities?
- Did we group the building with the business under Reg. §1.469-4, and was the grouping disclosed?
- If I sell the building, which suspended losses will actually be released, and which will stay stuck?
- Would the rent level between my business and my building hold up as arm's length?
