Data centers and real estate investment trusts (REITs) seem, at first glance, like a natural fit. Data centers are capital-intensive real estate assets. REITs are a familiar vehicle for owning real estate at scale while attracting a broad investor base, including tax-exempt and foreign investors, for whom the REIT may serve, in different ways, as a tax-efficient “blocker” entity. As demand for AI, cloud computing, and digital infrastructure continues to grow, it is not surprising that market participants are looking closely at the REIT structure.
But data centers also highlight a recurring tension in the REIT rules: The tax law is designed for passive real estate ownership, while modern data centers often require much more than a passive landlord.
That tension is not new. REITs have long been required to satisfy detailed asset and income tests intended to distinguish real estate ownership from the conduct of an operating business. The basic policy is straightforward: A REIT may generally avoid corporate-level tax if it primarily holds real estate and distributes its income, but it is not supposed to operate a business in corporate form without paying corporate tax.
Data centers put pressure on that distinction. To be clear, the REIT structure is not merely theoretical in the data center context. Treasury regulations include a data center example for asset-test purposes, and the IRS has issued private letter rulings addressing data center assets and related income streams. Those authorities are helpful, but they do not eliminate the need for careful analysis. The regulations are fact-specific, and private letter rulings cannot be cited as precedent. The practical question remains whether the particular facility, infrastructure, contracts, and services fit within the REIT rules.
A traditional real estate lease is relatively easy to analyze. A landlord owns a building and leases space to tenants. The rent is generally good REIT income, assuming the arrangement does not involve noncustomary services, excessive personal property, or other specialized facts, and the building is generally good REIT property. Data centers, by contrast, often involve highly specialized infrastructure. Tenants may require significant power capacity, redundant systems, cooling, security, connectivity, and other services necessary to keep servers running continuously. The more the landlord provides, the harder the question becomes: Is the REIT merely leasing real estate, or is it operating a technology and infrastructure platform?
The answer matters for both the REIT asset tests and the REIT income tests.
On the asset side, the question is whether the relevant property is real property for REIT purposes. The building shell may be relatively straightforward. But electrical systems, cooling equipment, backup power infrastructure, and other specialized components require closer analysis. Certain structural components can qualify as real property, while machinery and equipment serving an active function may not. In the data center context, that line can be difficult to draw because the property is valuable precisely because of the specialized infrastructure embedded in it.
Furthermore, current data center development timelines can create construction-phase asset test issues. Developers may need to make significant upfront deposits or prepayments to secure long-lead equipment—such as power infrastructure, cooling systems, and other specialized components—well before those items are delivered and permanently incorporated into the facility. That timing can raise questions under the 75% asset test, including how to treat construction-in-progress accounts, equipment deposits, and materials or components that are expected to become part of the real property. The National Association of Real Estate Investment Trusts has recently asked Treasury and the IRS to provide guidance on these issues in the 2026-2027 Priority Guidance Plan.
On the income side, the central question is whether amounts received by the REIT qualify as rents from real property. That analysis can become complicated when payments relate not only to space, but also to power, cooling, redundancy, monitoring, maintenance, or other operational services. The impermissible tenant services rules are particularly important. If impermissible tenant service income from a property exceeds 1% of the gross income from that property, all amounts received or accrued from the property are treated as impermissible tenant service income. That rule makes operational discipline especially important for data center REITs.
That does not mean data centers cannot be held through REITs. They can be, and in many cases the structure may be compelling. But the facts matter. A REIT that owns a data center shell and leases space on relatively conventional terms presents one set of issues. A REIT that is deeply involved in providing power, cooling, connectivity, and operational support presents another.
There are several tools for managing the risk. Some services may be provided through an independent contractor or a taxable REIT subsidiary. In appropriate cases, a taxable REIT subsidiary can perform activities that the REIT itself should not perform, with the subsidiary paying corporate tax on its income. That structure can preserve the REIT’s qualification while allowing the broader enterprise to deliver the services that tenants expect. But the structure has to be respected in practice, not just on paper. Transactions between the REIT and its taxable REIT subsidiary also need to be structured on arm’s-length terms, because the REIT rules include a 100% tax on certain redetermined rents, deductions, interest, and taxable REIT subsidiary service income.
The practical point is that data center REIT analysis is highly fact-specific. It requires understanding not only the legal documents but also the commercial and technical reality of the facility. Who owns the relevant infrastructure? Who provides the power? Who controls the cooling systems? What exactly is the tenant paying for? Are services separately charged or embedded in rent? Are the services customary for similar properties? Are they provided by the REIT, a taxable REIT subsidiary, or an independent contractor?
Those questions are becoming more important as the data center market expands. The growth of AI and cloud infrastructure has increased demand for facilities with extraordinary power and cooling needs. At the same time, investors are looking for efficient structures to fund development. The REIT structure can be a powerful capital-raising tool, but uncertainty around the tax treatment can affect how aggressively sponsors and investors are willing to use it.
The policy issue is that the REIT rules were not written with modern data centers in mind. They were built around a more traditional distinction between real estate ownership and operating businesses. Data centers blur that distinction because the real estate, infrastructure, and services are economically interdependent. A data center without adequate power and cooling is not merely less valuable; it may not be commercially usable at all.
For now, the best approach is careful structuring and careful diligence. Sponsors considering a REIT structure for data center assets should pressure-test the asset and income issues early, before the commercial model is locked in. Investors should understand how the REIT intends to manage services, infrastructure, and tenant-facing obligations. And both sides should recognize that small factual differences can drive meaningful tax consequences.
The bottom line is not that REITs are a poor fit for data centers. The bottom line is that data centers expose the limits of a tax framework built for simpler real estate assets. As digital infrastructure continues to grow, clearer guidance would be helpful. Until then, the key is to identify where passive real estate ownership ends and active operation begins—and to structure accordingly.
