Real Estate Investment Trusts (REITs) — Tax Rules, Qualification Tests, and Dividend Taxation
A real estate investment trust is a corporation or trust that invests in real estate and is allowed to deduct the dividends it pays to shareholders — effectively eliminating the corporate-level tax on income distributed to investors. Congress created the REIT structure in 1960 to allow small investors to participate in large-scale commercial real estate the same way they participate in stocks through mutual funds. REITs pay no corporate income tax on earnings they distribute — but to qualify, they must pass stringent income, asset, and distribution tests every year. At least 75% of gross income must come from real estate sources, at least 75% of assets must be real estate assets, and at least 90% of taxable income must be distributed to shareholders annually. When the rules are met, the REIT itself pays no tax on distributed income; shareholders pay ordinary income tax when they receive dividends. The result is a pass-through structure for real estate that trades on exchanges like stock and issues information statements like a corporation — a hybrid that has grown into a multitrillion-dollar sector of the U.S. economy, encompassing everything from apartment buildings and shopping centers to cell towers, data centers, and timberland.

Legal Authority
- 26 U.S.C. § 856(a) — "Real estate investment trust" definition: a corporation, trust, or association that is managed by trustees or directors; has transferable shares; would otherwise be taxable as a domestic corporation; is not a bank or insurance company; has beneficial ownership held by 100+ persons; and is not closely held
- 26 U.S.C. § 856(c)(2) — 95% income test: at least 95% of gross income (excluding prohibited transactions) must derive from dividends, interest, rents from real property, gains from non-dealer sales of real property and securities, and other qualifying sources
- 26 U.S.C. § 856(c)(3) — 75% income test: at least 75% of gross income (excluding prohibited transactions) must derive from rents from real property, interest on mortgage obligations, gains from real property sales (not dealer property), REIT dividends, tax abatements on real property, and qualifying temporary investment income
- 26 U.S.C. § 856(c)(4) — 75% asset test (quarterly): at least 75% of total assets must be real estate assets, cash and cash items, and government securities; no more than 25% in securities of any one issuer; no more than 5% of assets in any single issuer's securities; no more than 10% of any issuer's voting power
- 26 U.S.C. § 856(a)(5) — 100-shareholder requirement; § 856(h) — closely held prohibition (5 or fewer individuals may not own more than 50% — the "5/50 rule")
- 26 U.S.C. § 857(a) — Distribution requirement: the REIT rules apply only if the REIT distributes dividends equal to or exceeding 90% of REIT taxable income (excluding net capital gain) for the year; the "dividends paid deduction" effectively eliminates double taxation on distributed earnings
- 26 U.S.C. § 857(b) — REIT taxable income: income retained by the REIT (above the 90% distribution requirement) is taxed at the 21% corporate rate; capital gains retained by the REIT are taxed at the corporate capital gain rate, but shareholders may elect to treat those gains as if distributed (with a credit for the REIT's tax paid)
Implementing Regulations
The IRS regulations implementing REIT distribution and excise rules live at 26 CFR Part 55 — Excise Tax on Real Estate Investment Trusts and Regulated Investment Companies. Key provisions:
- § 55.4981-2 — Imposes a 4% excise tax on the "excess inclusion" between a REIT's "required distribution" for the calendar year and the amount actually distributed. The required distribution is 85% of the REIT's ordinary income plus 95% of the REIT's net capital gain income for the calendar year — a higher standard than the 90% income distribution requirement that determines REIT qualification. The excise tax is designed to prevent REITs from timing year-end distributions to avoid the income tests: a REIT that qualifies by distributing 90% of income but holds back 15% of ordinary income still owes 4% excise on that retained ordinary income. The excise applies on a calendar-year basis regardless of the REIT's own fiscal year. REITs report on Form 8612 (Return of Excise Tax on Undistributed Income of Real Estate Investment Trusts), due March 15 of the following year.
- § 55.4982-1 — Imposes the same 4% excise tax structure on Regulated Investment Companies (mutual funds and ETFs): the RIC must distribute at least 98% of ordinary income and 98.2% of capital gain net income during the calendar year. The higher thresholds (vs. the 90% REIT qualification standard) make the excise a meaningful compliance concern for funds that time large December distributions. RICs file Form 8613 (Return of Excise Tax on Undistributed Income of Regulated Investment Companies), also due March 15.
The practical significance of the excise: year-end distribution timing is critical for both REITs and mutual funds. A REIT that misses its December distribution deadline — say, the board declares a December 31 dividend but payment clears on January 2 — may face the 4% excise on the undistributed income that timed incorrectly. Funds with large unrealized gains that are forced to distribute must navigate the 98%/98.2% thresholds. The excise acts as a compliance backstop below the main REIT qualification rules.
The REIT Pass-Through Mechanics
Why REITs are tax-efficient: A regular C corporation pays 21% corporate income tax on earnings, then distributes after-tax dividends to shareholders who pay income tax again — double taxation. A REIT avoids the first tax by deducting dividends paid. If a REIT earns $100 million in rental income, distributes $90 million, and retains $10 million, it pays zero tax on the $90 million distributed (the dividends paid deduction offsets the income) and 21% on the $10 million retained. The $90 million flows to shareholders who pay personal income tax rates.
Shareholder taxation: REIT dividends are generally ordinary income — not "qualified dividends" eligible for the preferential 15–20% rate that applies to most corporate dividends. REIT shareholders typically pay ordinary income rates (up to 37%) on REIT dividends. However, the 2017 TCJA created a § 199A deduction that allows individual shareholders to deduct 20% of "qualified REIT dividends" (ordinary REIT dividends other than capital gain distributions), effectively reducing the top rate to 29.6%.
Capital gain distributions: When a REIT sells appreciated property and distributes the gain (potentially triggering depreciation recapture), that distribution retains its capital gain character in shareholders' hands — taxed at 20% (for those in the top bracket) rather than ordinary rates. This is one of the most favorable aspects of REIT investing: property appreciation flows through as capital gain.
Return of capital distributions: When a REIT distributes more than its current earnings (e.g., distributes depreciation tax losses as cash), part of the distribution is a "return of capital" — tax-free at the time received, but reduces the shareholder's cost basis, increasing eventual capital gain on sale.
Types of REITs
Equity REITs own physical real estate and generate revenue primarily from rents. Major sectors include: apartments (residential REITs), office buildings, retail (shopping centers and malls), industrial (warehouses and distribution), healthcare (hospitals, nursing homes, senior housing), and "net lease" properties (single-tenant properties where tenants pay operating costs). Equity REITs account for the majority of the REIT market.
Mortgage REITs (mREITs) invest in real estate loans and mortgage-backed securities rather than physical property. They earn income from interest — the spread between their borrowing rate and the rate on mortgage assets. mREITs are highly leveraged and interest-rate sensitive. They pass the REIT income tests because interest on mortgage obligations is qualifying 75% income.
Specialty REITs include cell tower REITs (where tower lease rents qualify as "rents from real property"), data center REITs, timberland REITs, and billboard/outdoor advertising REITs. The IRS has issued guidance ruling that various types of lease structures qualify as real property rents for REIT purposes.
Taxable REIT subsidiaries (TRS): A REIT can own up to 25% of its assets in taxable REIT subsidiaries — regular corporations that pay corporate tax. TRS entities allow REITs to provide non-qualifying services (hotel management, retail services) without contaminating the REIT's income tests. The TRS pays corporate tax; the REIT owns the TRS stock, which is a qualifying security asset.
The Qualification Tests in Practice
The 75% and 95% income tests and the quarterly asset tests are compliance requirements that REIT legal and accounting teams track continuously. A failure — even inadvertent — can disqualify the REIT and trigger back taxes for all years.
Income test traps: Non-qualifying income (operating business income, income from services provided to tenants that go beyond customary property management) can cause failures. Rent that varies based on tenant profitability (percentage rents based on net income) disqualifies; percentage rents based on gross revenue qualify. The IRS has ruled extensively on what counts as "rents from real property."
Asset test compliance: The quarterly measurement creates exposure if investments shift during the year. REITs may inadvertently exceed the 5% single-issuer limit if a security appreciates substantially. The Code provides a 30-day cure period for de minimis violations.
5/50 rule (closely held test): In the first year, the REIT is not required to satisfy the 100-shareholder and 5/50 rules. Afterward, these are annual tests. Public REITs that trade on exchanges satisfy these easily; privately offered REITs must track shareholder composition carefully.
How It Affects You
If you invest in publicly traded REITs through a brokerage account or 401(k): Most REIT distributions are ordinary income taxed at your marginal rate — not the 15–20% qualified dividend rate that applies to most corporate dividends. Your Form 1099-DIV will show ordinary dividends (Box 1a), qualified dividends (Box 1b — typically a small fraction for REITs), capital gain distributions (Box 2a, taxed at long-term capital gain rates), and return of capital (Box 3, tax-free at receipt but reduces your cost basis). The § 199A deduction reduces the effective rate on ordinary REIT dividends for individual taxpayers: if you're in the 32% bracket and receive $10,000 in qualified REIT dividends (non-capital-gain distributions), you deduct $2,000 and pay 32% on $8,000 — an effective rate of about 25.6% rather than 32%. Because of the ordinary-income treatment, REITs held in tax-deferred accounts (IRAs, 401(k)s) often have better after-tax economics than in taxable accounts where you're paying full ordinary rates annually. Consider concentrating your highest-yielding REITs (apartment, net lease, industrial) in tax-deferred accounts and lower-yielding appreciation-focused REITs in taxable accounts. Note: the § 199A deduction was scheduled to expire after 2025 under the TCJA sunset — verify whether the OBBBA extended it for the current tax year.
If you hold REIT shares in a self-directed IRA or 401(k): Standard REIT rental income and mortgage interest flowing to your IRA are not subject to UBTI — they're passive income excluded from the unrelated business income tax that otherwise applies to IRA investments in operating businesses. However, highly leveraged mortgage REITs that borrow to buy mortgage-backed securities may generate unrelated debt-financed income under § 514, creating UBTI exposure inside your IRA. If an mREIT generates more than $1,000 of UBTI for your IRA in a year, the IRA owes corporate-level tax on it — and the IRA custodian will issue a Form 990-T for the IRA to file and pay. Before investing in leveraged mREITs (Annaly Capital Management, AGNC Investment Corp, Starwood Property Trust) inside an IRA, check the REIT's investor relations materials or Form 10-K for UBTI disclosures, or ask IR directly. Equity REITs that own physical property and don't borrow against it generally don't generate UBTI.
If you're evaluating a private or non-traded REIT: Non-traded REITs satisfy the same federal tax qualification tests as publicly traded REITs, but their investor track record is substantially worse. Common structural issues: front-end sales commissions of 5–12% (your $100,000 investment starts at $88,000–$95,000); annual management fees of 1.5–2%; redemption programs that can suspend when the REIT needs liquidity; and NAV opacity — you often don't know what your shares are actually worth until a liquidity event years later. Before investing in any non-traded REIT, check whether it's registered with the SEC at sec.gov/edgar and whether it files annual 10-K and quarterly 10-Q reports (mandatory for most non-traded REITs that raise money publicly). For most investors, publicly traded REIT index exposure via Vanguard Real Estate ETF (VNQ) or Schwab US REIT ETF (SCHH) provides diversified REIT exposure with daily liquidity, transparent pricing, and expense ratios of 0.12–0.23% — structurally superior to non-traded alternatives that charge 7–12% upfront.
If you're a real estate company considering REIT conversion: Converting a C corporation's real estate portfolio to REIT status involves several non-trivial hurdles. The built-in gain rules under § 857(b)(6) mean that gains built into properties at the time of C corporation conversion remain subject to corporate-level tax when recognized — typically for 5 years after conversion. For portfolios with significant unrealized appreciation, this can make immediate conversion tax-inefficient. The organizational requirements — 100+ shareholders, freely transferable shares, no more than 50% owned by 5 or fewer individuals — typically require significant restructuring for a closely-held operating company. The most common path for private real estate operators is the UPREIT structure: instead of converting the entire company, you contribute individual properties to an existing publicly traded REIT's operating partnership in exchange for operating partnership units, deferring the gain on contribution (under § 721). See 721 UPREIT Exchange for the full mechanics. You preserve your economic interest and defer tax while gaining eventual liquidity when you convert OP units to REIT shares. The OBBBA clarified UPREIT conversion treatment, confirming deferral when specific conditions are met. Engage REIT-specialized tax counsel well before your target election year — REIT qualification errors in year one can disqualify the structure and trigger a 5-year re-election waiting period.
State Variations
States generally conform to the federal REIT pass-through structure, though state conformity varies. Most states allow a dividends-paid deduction for REITs equal to the federal deduction, so REITs pay minimal state income tax at the entity level. Property taxes on REIT-owned real estate are the more significant state tax burden — REITs are major property taxpayers in every state where they hold assets. Some states impose a franchise or minimum tax on REITs organized as corporations even if income tax is zero due to the dividends-paid deduction.
Pending Legislation
No major changes to the REIT tax structure are pending. The § 199A 20% deduction for qualified REIT dividends is scheduled to expire in 2025 as part of the TCJA sunset — legislation to extend or make permanent the § 199A deduction would affect REIT investor economics significantly. Congress has periodically addressed the REIT rules for new asset classes (e.g., the 2016 PATH Act clarified REIT treatment of cell towers, outdoor advertising, fiber networks), and further guidance on data center and clean energy REIT qualification is ongoing.
Recent Developments
The 2021 American Rescue Plan Act included provisions affecting REITs that hold government-backed mortgage securities. Treasury updated regulations in 2020–2022 clarifying the treatment of REIT interests in partnerships and tiered REIT structures. The IRS has issued favorable PLRs qualifying data centers, cell towers, and fiber optic cable infrastructure as "real property" for REIT asset and income test purposes. The growth of industrial and logistics REITs driven by e-commerce, and data center REITs driven by cloud computing, has made technology infrastructure one of the fastest-growing REIT sectors — generating extensive IRS guidance on whether digital infrastructure qualifies as "real property."
- Data center REITs and AI infrastructure boom (2024-2025): The AI infrastructure buildout — requiring massive data center capacity for training and inference — has driven explosive growth in data center REITs (Equinix, Digital Realty, Iron Mountain, QTS, Cyrus One). Data center REITs that lease space to hyperscalers (Microsoft Azure, AWS, Google Cloud) for AI workloads have seen portfolio values surge 40-60% in 2024-2025. IRS guidance confirming that data center space, cooling infrastructure, and power systems qualify as REIT "real property" has enabled efficient REIT structuring for the AI buildout. The AI capital expenditure wave is the most significant driver of REIT sector growth since the e-commerce/logistics boom.
- OBBBA REIT provisions: The One Big Beautiful Bill Act made several REIT-related changes. The OBBBA increased the REIT dividend deduction for foreign shareholders, modifying the FIRPTA (Foreign Investment in Real Property Tax Act) rules to encourage more foreign capital into U.S. real estate through REITs. The bill also clarified the treatment of REIT operating partnership (UPREIT) conversions — a common structure for private real estate operators who contribute properties to a publicly traded REIT's operating partnership in exchange for operating partnership units — confirming deferral treatment when specific conditions are met.
- Office REIT distress and work-from-home legacy: Office REITs have been the worst-performing REIT sector since 2020, as remote and hybrid work reduced occupancy at major office buildings in gateway cities. Several office REITs (Brookfield, Columbia Property Trust, Pimco's distressed office funds) have defaulted on mortgage debt or sold office properties at significant discounts. REIT distribution cuts — which affect shareholders who depend on REIT dividends — have been widespread in the office sector. The conversion of distressed office buildings to residential use has become a policy priority; the OBBBA included a temporary tax incentive for office-to-residential conversions that modifies normal cost segregation and depreciation rules.
- Residential REIT supply constraints and housing policy: Single-family rental REITs (Invitation Homes, American Homes 4 Rent) and multifamily apartment REITs (AvalonBay, Equity Residential, Camden Property Trust) have faced policy and regulatory scrutiny as housing affordability crisis deepens. Some states and municipalities have restricted institutional single-family home purchases; these restrictions don't directly affect REIT qualification but affect portfolio acquisition strategies. The OBBBA included a provision requiring disclosure of institutional single-family home ownership in residential real estate transactions — a transparency measure that doesn't restrict ownership but subjects large portfolio holders to public reporting.
