REIT subsidiary asset test rises to 25% in 2026

The One Big Beautiful Bill Act delivers a structurally important change to real estate investment trust regulation through Section 70439. The provision amends Section 856(c)(4)(B)(ii) of the Internal Revenue Code, restoring the taxable REIT subsidiary asset cap from 20% to 25%. The change applies to taxable years beginning after December 31, 2025, taking effect in REIT tax filings for fiscal year 2026 and beyond.

The shift looks small on paper. Five percentage points on an asset-test denominator does not generate dramatic headlines. But for REIT operators running hotel portfolios, healthcare facilities, data centers, or any property type that requires active business operations alongside passive real estate ownership, the additional 5% of total asset capacity translates into meaningful operational flexibility. Sponsors that had been bumping into the 20% ceiling now have headroom to expand their TRS-held businesses without restructuring or asset sales.

For investors holding REIT shares directly or through retirement accounts, the change does not affect dividend tax treatment, qualified business income deduction eligibility, or any other shareholder-level mechanic. The benefit accrues at the REIT level through an expanded operational scope, which may ultimately translate into better dividend coverage, larger distributions, or stronger asset diversification for shareholders. This article walks through the asset test mechanics, why the 5-point change matters, which property types benefit most, and how investors should think about it.

What the taxable REIT subsidiary asset test actually does

A real estate investment trust must derive most of its income from passive real estate sources to maintain its REIT election. Rents, mortgage interest, and gains on real property sales count as good REIT income. Income from active business operations, like running a hotel restaurant, providing concierge services, or operating an in-house management company, generally does not qualify.

The taxable REIT subsidiary structure solves this. A REIT can own a separate corporation, the TRS, that runs the active business operations. The TRS pays regular C corporation tax on its income, and the REIT collects dividends from the TRS as good REIT income. The structure lets a REIT participate in active business value creation while preserving its REIT status at the parent level.

To prevent REITs from morphing into operating companies that happen to own real estate, Congress imposed limits on how much of a REIT's total assets may be held in TRSs. The Section 856(c)(4)(B)(ii) asset test is the operational ceiling. Before TCJA, the cap was 25%. The Tax Cuts and Jobs Act of 2017 reduced it to 20%, partly to offset other corporate tax changes. OBBBA Section 70439 reverses that reduction, restoring the original 25% threshold.

The five-point change matters because most large REITs operate close to whatever the cap. They size their TRS-held operations against the regulatory ceiling, leaving a small buffer for valuation fluctuations and acquisition activity. Moving the ceiling from 20% to 25% gives those REITs an additional 5% of total asset capacity to deploy into TRS structures.

Why the 5 percentage point change matters for REITs

REITs do not simply expand TRS holdings to fill available cap space immediately. Large operating decisions require board approval, capital allocation, and sometimes acquisition pipelines. The benefit of the higher cap shows up over time, as REITs evaluate growth opportunities they previously had to decline or restructure around.

Three operational shifts matter most.

First, hotel REITs gain the capacity to bring more property operations in-house. The TRS structure is essentially mandatory for hotel REITs because hotels are inherently active businesses. Brand affiliation, revenue management, food and beverage operations, and labor are all run through the TRS. A hotel REIT near the 20% cap was constrained in the amount of hotel operating value it could absorb before having to externalize operations to third-party managers, thereby diluting margins. The 25% cap relieves that constraint for portfolios with substantial unrealized operating value.

Second, healthcare REITs gain flexibility around skilled nursing, senior living, and active medical office configurations. Properties that combine real estate ownership with active service delivery (such as RIDEA structures in healthcare REIT terminology) require TRS holdings to capture operating economics. The expanded cap makes RIDEA portfolios more viable and supports continued growth in healthcare property segments where active operations are inseparable from real estate value.

Third, data center and specialty industrial REITs gain capacity for ancillary services. Modern data centers earn substantial value from connectivity services, technical support, and managed infrastructure offerings that sit outside passive real estate income. Specialty industrial REITs running cold storage, document management, or specialized logistics similarly need TRS structures for the operating layer.

For real estate investors structuring activities through Partnerships or S Corporations, the REIT-level change does not flow through directly. Still, it does affect the competitive dynamics in property segments where listed REITs are major buyers. Pricing and acquisition appetite from REIT bidders may shift in property types that depend heavily on TRS flexibility.

How much TRS capacity does the 25% cap add to REITs

The dollar magnitude of the change depends on REIT size. The 5-point delta applies to total asset value, so larger REITs gain proportionally more absolute capacity. Three illustrative scenarios show the scale.

A mid-size REIT with $5 billion in total assets had a TRS asset cap of $1 billion under the 20% rule. Under the 25% rule, the cap rises to $1.25 billion. The REIT gains $250 million of additional capacity to deploy into TRS-held operations. For a REIT actively building out an operating platform, that is enough to absorb a sizable acquisition or to expand existing operations into adjacent service lines.

A large REIT with $20 billion in total assets had a TRS cap of $4 billion. The new 25% cap raises that to $5 billion, a $1 billion increase in capacity. At that scale, the additional capacity supports portfolio-level diversification moves that were not feasible under the lower ceiling.

A small REIT with $500 million in total assets had a TRS cap of $100 million. The new cap raises that to $125 million. The $25 million in additional capacity is meaningful for smaller REITs evaluating growth in operating activities, even though the absolute scale is much lower.

For individual investors holding REIT shares in taxable accounts, the institutional change does not require any direct action. Standard portfolio management practices, including Tax loss harvesting on REIT positions in down years, continue to apply.

How do TRS taxes interact with REIT shareholder returns

TRS earnings are taxed at the regular C corporation rate of 21%. When the TRS pays a dividend to the REIT parent, the REIT receives the dividend as good REIT income. The REIT then pays distributions to its shareholders, most of which are ordinary dividends taxed at the shareholder's marginal rate (with the qualified business income deduction available to non-corporate shareholders, subject to limits and phase-outs).

The two-layer tax structure means TRS income is effectively taxed twice. The TRS pays 21% federal corporate tax. The shareholder pays ordinary income tax on the eventual distribution. For a top-bracket individual shareholder, the combined effective rate on TRS-sourced income can run substantially higher than the rate on direct REIT rental income.

Despite this two-layer tax cost, REITs use TRS structures because the alternative of active operations would result in the loss of REIT status entirely, subjecting all REIT income to corporate tax (not just the active portion). The TRS structure is the regulatory price of operating flexibility, and the 25% cap simply allows more of that flexibility per dollar of total REIT assets.

Investors holding REIT shares in tax-advantaged accounts, including Traditional 401k and Roth 401k plans, sidestep the shareholder-level ordinary income tax entirely. For long-term real estate exposure in retirement accounts, the higher TRS cap means REITs can pursue a wider range of total-return strategies without worrying that the asset test will be a binding constraint.

Which REIT property types benefit from the 25% cap

Different REIT property types benefit from the higher cap to varying degrees, depending on how much of their portfolio value is tied to TRS-held operations.

Hotel REITs benefit most directly. Lodging operations are inherently active, and the entire economic value of operating a hotel portfolio runs through TRS structures. Hotel REITs that had been near the 20% cap can now absorb additional operating value, which may translate into more aggressive acquisition activity in the hotel sector or stronger margins on existing portfolios.

Healthcare REITs gain meaningful flexibility for RIDEA portfolios. Skilled nursing, senior living, and active medical office configurations all require TRS holdings to capture full operating economics. The 25% cap supports continued portfolio expansion in service-intensive healthcare segments.

Industrial and logistics REITs benefit moderately. Most industrial real estate generates passive rental income, so TRS structures are less central than in hotels or healthcare. However, specialty industrial segments such as cold storage and certain logistics operations can absorb the additional capacity without affecting operating income.

Office and retail REITs benefit least, because their core income is passive rental income from long-term leases. The TRS cap rarely binds for these property types, so the 5-point increase is functionally neutral for most office and retail portfolios. Some retail REITs with active business components, such as outlet center management or specialized leasing operations, may see modest benefits.

Self-storage REITs gain capacity for ancillary services. While self-storage rental is largely passive, ancillary services such as moving truck rentals, packing supply sales, and tenant insurance are operated through TRS structures. The higher cap supports the continued growth of these service offerings.

For real estate developers structuring properties through C Corporations, the REIT-level change does not flow through directly. Still, it does affect what listed REIT bidders are willing to pay for properties with operating components. Sellers of hotels, healthcare facilities, and active-service properties may see broader bidder pools after January 1, 2026.

How should REIT investors position for the new cap

For individual investors seeking to build real estate exposure through REIT shares, the higher TRS cap is a small positive at the institutional level but does not require any portfolio adjustments. Asset allocation, sector concentration, and tax-location decisions remain governed by the same considerations as before OBBBA.

Three portfolio considerations are worth refreshing in 2026:

• Sector tilt within REIT exposure now slightly favors property types that benefit most from the cap restoration (hotels, healthcare, specialty industrial)
• Tax-location decisions for REIT holdings continue to favor tax-advantaged accounts because REIT distributions remain mostly ordinary income at the shareholder level.
• Position sizing for individual REIT names should account for TRS exposure (a REIT with substantial TRS-held operations carries different risk-reward than a pure passive landlord)

Investors using Depreciation and amortization strategies on directly held real estate alongside REIT positions should continue to model the two exposures separately, as the institutional REIT change does not affect the depreciation profile of personally owned real estate.

For high-net-worth investors with substantial real estate exposure, coordinating REIT positions with Sell your home timing and the Augusta rule for short-term home rentals provides a layered approach to real estate tax efficiency that the institutional REIT change supplements but does not replace.

How does the 25% cap interact with other OBBBA changes

Section 70439 sits alongside several other OBBBA provisions that affect real estate investors and operators. The expansion of Section 179 expensing limits, the permanent extension of bonus depreciation in modified form, and changes to opportunity zone deadlines all interact with REIT-level operations and direct real estate ownership in different ways.

For investors evaluating their full real estate tax picture in 2026, working through how the various OBBBA provisions stack against existing positions is a meaningful planning exercise. Some provisions accelerate deductions on direct ownership. Others affect institutional vehicle economics. The TRS cap restoration is part of a broader real estate tax refresh that affects both direct owners and institutional investors.

Frequently asked questions

Q: What changed under Section 70439?

A: Section 70439 amends IRC Section 856(c)(4)(B)(ii) by replacing "20 percent" with "25 percent." The amendment raises the maximum percentage of a REIT's total assets that can be held in taxable REIT subsidiaries. The change applies to taxable years beginning after December 31, 2025.

Q: Does this change affect REIT shareholder dividend tax treatment?

A: No. Section 70439 affects only the asset test at the REIT entity level. Shareholder tax treatment of REIT dividends, including the qualified business income deduction available to non-corporate shareholders within applicable limits, is unchanged. Investors do not need to take any action on existing REIT positions.

Q: Why does the TRS structure exist in the first place?

A: REITs must derive most of their income from passive real estate sources to maintain REIT status. Active business operations like hotel management, healthcare service delivery, or specialty data services do not qualify as good REIT income. The TRS structure lets a REIT own a separate corporation that runs active operations, paying regular C corporation tax, while the REIT collects dividends as good REIT income.

Q: Which REIT property types benefit most from the higher cap?

A: Hotel REITs benefit most because hotel operations are entirely active and run through TRS structures. Healthcare REITs benefit substantially through RIDEA portfolio expansion. Specialty industrial, data center, and self-storage REITs gain moderate flexibility for ancillary services. Office and retail REITs see little practical change because their TRS exposure is typically well below the cap.

Q: Does the change affect REITs held inside a retirement account?

A: Not directly. The asset test operates at the REIT entity level. Retirement accounts remain tax-advantaged vehicles for holding REIT shares, and the higher cap may indirectly support stronger long-term REIT performance by expanding operational flexibility, but no direct shareholder action is required.

Q: When did the 25% cap apply previously?

A: Before the Tax Cuts and Jobs Act of 2017, the TRS asset test was 25%. TCJA reduced the cap to 20% as part of broader corporate tax changes. OBBBA Section 70439 restores the original 25% threshold, returning the asset test to its pre-2018 level.
