How does Colorado tax a REIT and its taxable REIT subsidiary?

Rolling conformity and the federal REIT regime at the state level

Colorado's income tax statute defines "internal revenue code" as the federal Internal Revenue Code of 1986, as amended, and other federal income tax law, "as the same may become effective at any time or from time to time, for the taxable year" (CRS 39-22-103(5.3)). That is rolling, not fixed-date, conformity: Colorado does not reenact a snapshot of the IRC each year and does not require a separate legislative act to pick up federal amendments. CRS 39-22-103(11) reinforces the point by directing that terms used elsewhere in the income tax article carry their federal meaning unless the Colorado statute says otherwise. The corporate income tax itself is imposed on "Colorado net income" under CRS 39-22-301, and Colorado net income begins with federal taxable income, adjusted by the addition and subtraction modifications enumerated in CRS 39-22-304(2) and (3). None of those modifications target REIT status, the dividends paid deduction, or IRC section 857 by name.

The consequence for a REIT is direct: because Colorado has not decoupled from IRC section 857, a REIT's federal dividends paid deduction is embedded in the federal taxable income figure Colorado starts from, and it flows through without a Colorado-specific addback. CRS 39-22-503(1)(a) adopts the federal definition of "real estate investment trust" from IRC section 856 outright, and CRS 39-22-503(1)(b) makes the computation explicit: the "net income" of an entity taxed as a REIT for federal purposes is its federal real estate investment trust taxable income under IRC section 857, adjusted only by the ordinary CRS 39-22-304(2) and (3) modification schedule that applies to any C corporation. A REIT that has distributed enough of its taxable income to zero out or substantially reduce its federal REIT taxable income arrives at the Colorado computation with the same result.

The captive REIT rule: disclosure, not disallowance

Many states responded to REIT structuring that grew common in the late 1990s and 2000s, a parent corporation, often outside the real estate industry, holding real property through a wholly or majority owned REIT subsidiary to generate a state-level dividends paid deduction, by enacting captive REIT statutes that add back the deduction or pull the REIT into the parent's combined report. Colorado took a different route in HB 09-1093 (2009 Colo. Sess. Laws ch. 75). That act defined the captive REIT in Part 5 of Article 22, alongside a parallel captive regulated investment company definition at CRS 39-22-501(2), and put both definitions to work in a new disclosure statute, the Colorado Reportable Transactions Act (CRS 39-22-651 to 39-22-659), rather than in the corporate modification schedule at CRS 39-22-304.

CRS 39-22-503(2)(a) defines a "captive real estate investment trust" as a REIT whose shares or beneficial interests are not regularly traded on an established securities market and more than fifty percent of whose voting power or value is owned or controlled, directly, indirectly, or constructively, by a single entity that is treated as an association taxable as a corporation under the Internal Revenue Code and that is not exempt from federal income tax under IRC section 501(a). Constructive ownership is measured under IRC section 318(a), as modified by IRC section 856(d)(5) (CRS 39-22-503(3)). CRS 39-22-503(2)(b) carves out a REIT intended to become regularly traded that satisfies the listing and shareholder-count conditions of IRC section 856(a)(5) and (a)(6) through the transition rule at IRC section 856(h)(2), unless it fails to become regularly traded within the time that rule allows.

CRS 39-22-503(4)(a) does not reclassify a captive REIT. It defines "association taxable as a corporation," the phrase used in the owner test of (2)(a), and excludes from it a REIT other than a captive REIT, a qualified REIT subsidiary of a non-captive REIT, a listed Australian property trust, and a qualified foreign entity. Those owners do not make a REIT captive, so a REIT held by a listed or otherwise non-captive REIT is outside the definition.

The consequence of captive status is disclosure. A transaction between a captive REIT and its more than fifty percent beneficial owner is a "listed transaction" (CRS 39-22-652(5)(b)). A taxpayer that participates in a listed transaction must disclose it in a statement filed with its next return, in the form the Department specifies (CRS 39-22-653(2), (5)(b)), and where a taxpayer has multiple captive REIT transactions in one year, it may file a single disclosure showing the name and ownership of each entity and each entity's total assets and total income earned before any dividends paid deduction (CRS 39-22-653(2)). Failure to disclose a listed transaction carries a penalty of up to fifty thousand dollars, in addition to any other penalty (CRS 39-22-655(1)(b), (2)). The Department's rule defines the covered transactions broadly, including dividends, management fees, rent, loans, interest, and capital contributions between the captive REIT and its owner, and requires disclosure only where the return reflects a Colorado tax benefit, such as rent paid by an operating affiliate to the captive REIT that reduces Colorado taxable income (1 CCR 201-2, Rule 39-22-652). None of these provisions takes away the CRS 39-22-503(1)(b) computation or the dividends paid deduction. Colorado's approach puts a captive structure in front of the Department on the return rather than disallowing its tax result.

Combined reporting: where the REIT and the TRS each stand

Colorado's combined reporting standard turned over with the 2026 tax year, and the answer for any current year comes from the new one. CRS 39-22-303(11.5)(b)(I), enacted by HB24-1134 (2024), provides that for tax years beginning on and after January 1, 2026, all members of an affiliated group of C corporations, wherever incorporated or domiciled, that are members of a unitary business must file a combined report as a combined group. The inquiry is unitary rather than mechanical, and the statute's reference to members wherever incorporated or domiciled means a foreign charter does not by itself hold an affiliate out of the group, subject, for 2026, to the exclusion in CRS 39-22-303(8) for corporations with 80 percent or more of their property and payroll outside the United States. CRS 39-22-303(12)(a) supplies the affiliated group definition the combined reporting rules operate on: one or more includable C corporations connected through common ownership of more than fifty percent of the voting power and more than fifty percent of each class of nonvoting stock with a parent that is also an includable C corporation.

The three-of-six test has not disappeared, because open years predate the change. For tax years beginning before January 1, 2026, CRS 39-22-303(11) required an affiliated group to file a combined report only where the group satisfied at least three of six enumerated unity tests in the current tax year and the two preceding tax years. The six tests look at intercompany sales and purchases exceeding half of gross receipts, shared services exceeding half of the affiliate's services in five or more listed categories without arm's length pricing, intercompany long-term debt exceeding twenty percent of the borrowing affiliate's total long-term debt, substantial use of a common affiliate's intangible property, more than half common board membership, and common officers in at least twenty-five percent of the top twenty officer positions. That counting exercise governs every open earlier year and nothing after it, and a group that counted its way outside a combined report for 2025 should not carry the conclusion into 2026, since a unitary business standard asks a different question and does not turn on the absence of any three enumerated factors.

Where the REIT itself stands is an open question. Colorado taxes a REIT as a corporation (1 CCR 201-2, Rule 39-22-503), CRS 39-22-103(2.5) defines "C corporation" as any organization taxed as a corporation for federal income tax purposes, and the combined reporting statute, under the three-of-six test that governs earlier open years and under the unitary standard now in force alike, operates on affiliated C corporations. Read together, those texts support treating a REIT that meets the ownership and unity tests as a member of the combined group, with its own net income computed under CRS 39-22-503(1)(b). The competing reading treats that separate statutory computation, which ties the REIT's Colorado net income to its federal REIT taxable income, as a reason to keep the REIT outside the group. The statute does not resolve the point expressly, and captive status does not decide it either way: CRS 39-22-503(4)(a) is part of the captive REIT definition, not a rule about which entities are C corporations, and the captive REIT provisions govern disclosure, not combination. A taxable REIT subsidiary is on firmer ground. It was never a candidate for conduit treatment, since IRC section 856(l) defines it as a regular taxable corporation; it is an includable C corporation without qualification, and whether it must combine with other Colorado affiliates turns on the ordinary unity analysis, which for tax years beginning in 2026 and after means whether it is a member of a unitary business with them, with nothing REIT-specific about it either way.

Apportioning the taxable REIT subsidiary: market-based sourcing

Colorado apportions a C corporation's income using a single sales factor under CRS 39-22-303.6, effective for tax years beginning on or after January 1, 2019. Receipts from services are included in the Colorado numerator "to the extent the service is delivered to a location in Colorado," and Department guidance construes delivery location as the market for the service rather than the location of the taxpayer's employees or offices. For a taxable REIT subsidiary earning property management, asset management, or leasing fee income tied to Colorado real estate, the Department's rule treats management services as professional services, sourced for a business customer to the state where the customer principally manages the contract and for a related-party customer to where that party receives the service, while services physically performed at a Colorado property are sourced to the property (1 CCR 201-2, Rule 39-22-303.6-10); the location of the subsidiary's own personnel does not control the answer.

That market-based result also does independent nexus work. Colorado's corporate income tax nexus standard, as the Department's Corporate Income Tax Guide describes it, requires that the minimum protections of Public Law 86-272 be exceeded and that the corporation have substantial nexus with the state. Public Law 86-272 protects only the solicitation of orders for sales of tangible personal property, so it offers a taxable REIT subsidiary providing management or advisory services no shelter. Department guidance describes a factor-presence approach to substantial nexus, treating a corporation as having Colorado nexus if its Colorado property or payroll exceeds fifty thousand dollars, if its Colorado sales exceed five hundred thousand dollars, or if any of those categories reaches twenty-five percent of the corporation's total. A taxable REIT subsidiary whose Colorado-sourced management fees clear that sales threshold has Colorado nexus on its own, independent of whatever filing position its REIT parent takes.

Dividends received by corporate shareholders of the REIT

Because Colorado's computation starts from federal taxable income and CRS 39-22-304 contains no REIT-specific modification, whatever dividends received deduction treatment federal law gives a corporate shareholder's REIT dividend carries through to Colorado unchanged. Under IRC section 243(d)(3), dividends paid by a REIT are generally not eligible for the federal dividends received deduction in the first place, so a Colorado corporate shareholder typically has no federal deduction to protect and no Colorado modification is needed to reach that result. REIT dividend income is included in federal taxable income and, by extension, Colorado taxable income, subject to whatever capital gain dividend or return-of-capital characterization applies at the federal level under IRC section 857(b)(3) and section 301(c). Colorado has no separate dividends received deduction regime of its own that would change this outcome for a corporate shareholder of a REIT.

Practical structuring questions: fee income and nexus through partnerships

The structuring pattern common through the late 2010s, a REIT holding Colorado real estate indirectly through one or more partnerships, with a taxable REIT subsidiary earning management or leasing fee income from those properties, raises two separate nexus questions rather than one. The first is the REIT's own Colorado nexus. An out-of-state REIT that is a partner in a partnership doing business in or owning property in Colorado does not avoid Colorado nexus by holding the real estate a level removed; Colorado's nonresident partner rules at CRS 39-22-601(5.5), which govern tax years beginning on and after January 1, 2024, treat the partnership's Colorado activity as generating Colorado-source income to the partner. A corporate partner such as a REIT cannot be included in the partnership's composite return (CRS 39-22-601(5.5)(d)(II)(B)), so the partnership must obtain the partner's agreement to file and pay or otherwise satisfy the statute's payment requirements, and the REIT files its own Colorado return. Ownership through a pass-through entity does not insulate an out-of-state owner from Colorado filing obligations.

The second is the taxable REIT subsidiary's own nexus, discussed above, independent of the REIT's filing position and turning on the subsidiary's own Colorado-sourced receipts and property. A structure is better evaluated as three separate questions than one combined judgment call: whether the REIT has a Colorado filing obligation because of the underlying partnership's activity, whether the REIT's ownership structure makes it a captive REIT under CRS 39-22-503(2), which matters where a single non-exempt corporation holds the REIT and brings the listed transaction disclosure with it, and whether the taxable REIT subsidiary independently clears Colorado's nexus thresholds and, if so, whether it belongs in a combined report with other Colorado affiliates under the unitary standard, or for earlier open years the unity tests.

Practice notes

The recurring analytical error is treating "REIT taxation" as a single question when Colorado's statute asks three: is the REIT captive, and if so has every transaction with its majority owner that produces a Colorado tax benefit been disclosed; is its taxable REIT subsidiary independently taxable and apportioned, which it always is; and does either entity, or any other Colorado affiliate in the structure, need to combine. The captive REIT question deserves attention early wherever a single corporate parent controls the REIT, since the cost of getting it wrong is a penalty of up to fifty thousand dollars for an undisclosed listed transaction (CRS 39-22-655(1)(b)) and a structure that reaches the Department without the disclosure the statute requires. Whether the REIT itself belongs in the combined group is the open question discussed above and should be decided, and documented, on the texts rather than assumed in either direction. The subsidiary's exposure should be modeled on its own facts, since market-based sourcing can create meaningful Colorado receipts, and Colorado nexus, from fee income tied to Colorado property even where the subsidiary has no employees or office in the state. And the combined reporting standard has already changed rather than being something to watch for: CRS 39-22-303(11.5)(b) combines all members of an affiliated group of C corporations that are members of a unitary business for tax years beginning on and after January 1, 2026, so a group that kept a REIT-adjacent affiliate outside a combined group by counting three of six unity tests is relying on a rule that now governs only its open earlier years, and the current-year answer has to be worked again on unitary principles.
