What Is Impermissible Tenant Service Income for REITs?

Impermissible tenant service income, or ITSI, is money a Real Estate Investment Trust receives for providing non-customary services directly to its tenants, such as maid service inside individual units, concierge assistance, valet parking, or a security guard dedicated to a single tenant. Because a REIT has to earn most of its income passively, the tax code strips ITSI out of “rents from real property,” which is the qualifying bucket a REIT relies on to pass its annual income tests. Small amounts trigger a penalty tax; slightly larger amounts can disqualify all of a property’s rent; and a pattern of failures can cost the entity its REIT status entirely.

What Makes a Service Impermissible

The tax code lets a REIT include, inside “rents from real property,” charges for services “customarily furnished or rendered in connection with the rental of real property.”¹ Customary services are the things any reasonable landlord provides to keep the building functional: running elevators, heating and cooling common spaces, cleaning lobbies and stairwells, collecting trash, maintaining the building envelope.

ITSI is everything else. The statute treats it as any amount a REIT receives, directly or indirectly, for services furnished to tenants or for managing the property, beyond what is customary.² The IRS has long treated maid service inside an individual unit as the classic non-customary service, because it benefits the tenant personally rather than maintaining the building.³

The decisive question is whether the service maintains the building as a whole or caters to a specific tenant’s convenience. A few examples show how the line falls in practice:

Cleaning lobbies, hallways, and stairwells is customary; daily cleaning of an individual office suite or apartment is not.³
Providing non-metered heat, light, and basic utilities to the building is customary.
Operating a building-wide security desk or alarm system is generally permissible; assigning a dedicated guard to one tenant’s floor is not.
Elevator and boiler maintenance is customary by definition.
Concierge service, valet parking, and handling package delivery to individual units are not customary landlord functions and produce ITSI.
Providing data servers, proprietary machinery, or other personal property for a tenant’s use produces ITSI, because the charge stems from personal property rather than the real estate.

The “customarily furnished” standard also shifts with property type. Providing electricity and physical security to a telecommunications tower has been treated as customary because those services are standard for that kind of asset.³ The same service in a different context might not qualify, so each property type has to be evaluated on its own terms.

Why ITSI Is Dangerous: The 1% Cliff and the 150% Cost Floor

Two mechanical rules make ITSI far more punishing than its size would suggest.

The first is a cliff. If total ITSI from a single property exceeds 1% of all amounts the REIT received from that property during the year, the penalty does not scale proportionally. Every dollar the REIT collected from that property is reclassified as impermissible tenant service income.⁴ A REIT that collects $10 million in rent from a building and $101,000 in impermissible service fees does not lose just the $101,000. It loses the full $10.1 million from qualifying income.

The second rule blocks the obvious workaround. The amount treated as received for any impermissible service cannot be less than 150% of the REIT’s direct cost of providing that service.² If the REIT spends $50,000 delivering a non-customary service and charges the tenant only $60,000, the IRS treats it as having received $75,000. Charging tenants a token fee to stay under the 1% threshold does not work.

How ITSI Affects the 75% and 95% Income Tests

A REIT has to pass two gross income tests every year. At least 75% of gross income must come from real-estate sources, mainly rents from real property, mortgage interest, and gains on real estate sales. At least 95% must come from those sources plus passive investment income like dividends and interest.¹

ITSI is expressly excluded from “rents from real property,” so it cannot help the REIT clear either threshold.² It still counts in gross income, though, which means it shrinks the numerator and inflates the denominator at the same time. Combined with the 1% cliff, that compounding effect is what makes ITSI a threshold-level concern rather than a marginal one.

Structuring Around ITSI: TRS and Independent Contractors

Modern REITs need to offer competitive amenities, so the practical question is not whether to provide non-customary services but how to route the income somewhere other than the REIT itself. The code offers two escape valves.

Taxable REIT Subsidiary

A Taxable REIT Subsidiary is a regular corporation the REIT owns, and which has jointly elected with the REIT to be treated as a TRS. The TRS pays corporate income tax on its earnings, but its existence lets the parent REIT keep its status. The TRS performs the services that would otherwise generate ITSI, such as specialized cleaning, concierge, property management, and tenant-specific security. Because the statute treats services furnished through a TRS as not furnished by the REIT, the income never taints the REIT’s qualifying rents.² The TRS election is irrevocable unless both parties consent to revoke it. One structural limit: a TRS cannot directly operate or manage a hotel or health care facility, though it can hire an eligible independent contractor to do so.

Independent Contractor

The second option is simpler. A REIT can hire an independent contractor to provide non-customary services to its tenants, and the resulting income is not treated as ITSI, provided the REIT itself does not derive or receive any income from that contractor.² The contractor bills tenants directly. If the REIT collects management fees, profit-sharing, or any other revenue from the contractor, the exception fails and the service income becomes ITSI.

The 100% Excise Tax on Non-Arm’s-Length TRS Transactions

The TRS structure creates an obvious temptation to shift income between the tax-exempt REIT and the taxable TRS. The code answers with one of the harshest penalties on its books. A 100% excise tax applies to redetermined rents, redetermined deductions, excess interest, and redetermined TRS service income whenever a transaction between the REIT and its TRS is not on arm’s-length terms.⁵

In practice the IRS recalculates what the TRS should have paid the REIT, or vice versa, at arm’s length. If the TRS underpays the REIT for rent, or the REIT overpays the TRS for services, the excess is taxed at 100%. Every dollar of the shifted amount goes to the IRS. That is why REITs with TRS structures commission independent appraisals and document intercompany pricing as if they were dealing with a stranger.

What Happens if the Income Tests Fail

Failing the 75% or 95% income test does not automatically destroy a REIT’s status. If the failure was due to reasonable cause and not willful neglect, and the REIT files a detailed schedule identifying each item of non-qualifying income, it can keep its election.¹

Keeping the election is not free. The REIT owes a penalty tax equal to the greater of the shortfall under the 95% test or the shortfall under the 75% test, multiplied by a fraction that approximates the REIT’s overall profitability.⁶ The math works out to a tax roughly proportional to the profits embedded in the non-qualifying income.

If the failure is not due to reasonable cause, the REIT loses its election entirely. The entity is then taxed as a regular corporation at the 21% rate, loses the dividends-paid deduction that normally zeroes out its taxable income, and cannot re-elect REIT status for five years. That is the outcome the entire ITSI framework is built to prevent, and it is why REITs treat the line between customary and non-customary services as worth structuring around rather than pushing against.
