Renting Property to Your Own Business: The Self-Rental Rule
Why rent income from your own company cannot shelter passive losses, why a loss on that property stays passive, and the grouping election that changes the outcome.
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
When you rent property to a business in which you materially participate, the self-rental rule treats net rental income as non-passive — it cannot absorb losses from other passive activities — while a net rental loss stays passive and cannot offset business income. Grouping the rental with the business changes the result.

What does the rule do?
| Result for the year | Without grouping | With a valid grouping election |
|---|---|---|
| Net rental income | Non-passive: taxed as ordinary income, cannot offset passive losses, and treated as trade or business income that is generally outside the net investment income tax | Part of the active business: non-passive and outside the net investment income tax |
| Net rental loss | Passive: deductible only against passive income | Offsets the business's income |
| Sale of the building | Gain counts as rental activity income, so the year's net income from the building (gain included) is generally non-passive; suspended losses are released on a taxable sale to an unrelated buyer | Gain treated with the business activity |
The rule exists to stop owners from creating "passive" income from their own business to absorb unrelated passive losses.
When can the rental and the business be grouped?
The regulations allow a rental activity to be grouped with a trade or business when the two form an appropriate economic unit and either one is insubstantial relative to the other or every owner of the business has the same proportionate ownership in the rental (in which case only the part of the rental used by the business is grouped). The common case — the owner holds the building in an LLC and the operating company in an S corporation, both 100 percent — generally qualifies. The grouping is disclosed on a written statement with the original return for the first year and is binding in later years unless it was clearly inappropriate or a material change in facts makes it so.
What about the net investment income tax?
Rent from a self-rental is excluded from net investment income where the rental is grouped with, or recharacterized as non-passive because of, a business in which the owner materially participates. That exclusion can be worth more than the passive-loss effect.
What keeps the arrangement defensible?
A written lease at fair market rent, actual payment, the building titled in the entity that reports the rent, and consistent treatment on both returns. Rent set far above or below market invites recharacterization: too high can be a disguised distribution or compensation; too low shifts income to the business.
Why hold the building separately at all?
Liability separation, the ability to sell the business without the real estate, a different ownership mix for the property, and keeping real estate out of a C corporation. The self-rental rule is the tax cost of that design, and the grouping election is how it is managed.
Frequently asked questions
Can a self-rental loss offset my S corporation income without grouping?
No. The loss stays passive. Grouping is what allows it.
Does the grouping election affect real estate professional status?
It is separate; a real estate professional has other routes to non-passive treatment, but the grouping still matters for the net investment income tax.
What if my spouse owns the building and I own the business?
If you file a joint return, spouses are treated as one taxpayer under the passive activity rules, so the identical-ownership test is generally met and grouping is available if the two form an appropriate economic unit.
Can I regroup later?
Only if the original grouping was clearly inappropriate or a material change in facts makes it clearly inappropriate — or once, in the first year you owe the net investment income tax; the grouping is otherwise binding.
