A Practical Guide
A 10% headline yield on a BDC and a 10% headline yield on a dividend-paying blue-chip stock are not the same thing once taxes enter the picture. Because BDCs, REITs, and mREITs are structured around a 90%-of-income distribution requirement in exchange for avoiding corporate-level tax, the character of what they distribute is fundamentally different from a typical corporate dividend—and that difference can meaningfully change an investor's actual after-tax return.
A note before starting: tax law is complex, varies by individual circumstance, and changes over time. This guide explains the general framework as it commonly applies, not personalized tax advice. A tax professional should always be consulted for an individual's specific situation.
Most dividends from ordinary U.S. corporations qualify for the preferential "qualified dividend" tax rate (the same lower rates that apply to long-term capital gains: 0%, 15%, or 20% depending on income) provided certain holding-period requirements are met. This favorable treatment exists because the underlying corporation has already paid corporate income tax on those earnings before distributing them.
BDCs, REITs, and mREITs generally don't pay corporate income tax at all. Because that income was never taxed at the corporate level, most of what these entities distribute does not qualify for the lower qualified-dividend rate. Instead, it's typically taxed as ordinary income, at the investor's regular marginal income tax rate. This is the single most important tax concept to understand across all three asset classes: the high yields these investments offer are, in large part, a reflection of pre-tax income being passed through directly to the investor.
BDCs elect to be treated as Regulated Investment Companies (RICs) under the Internal Revenue Code—the same tax structure used by traditional mutual funds. BDC distributions are typically broken into several distinct components, each taxed differently:
A note on "spillover" distributions: Because RICs must distribute at least 90% of taxable income to maintain their tax status, BDCs sometimes carry forward a portion of one year's taxable income into the next year's distributions. This is a normal mechanical feature of RIC taxation and doesn't necessarily indicate anything about the BDC's underlying financial health.
The exact split between ordinary income, capital gains, and return of capital is reported on Form 1099-DIV (Box 1a: Total ordinary dividends; Box 1b: Qualified dividends; Box 2a: Capital gain distributions; Box 3: Return of capital). Most BDCs also publish a "tax characterization of distributions" summary on their investor relations website each year.
Equity REIT distributions follow a broadly similar framework to BDCs, but with one significant additional wrinkle: the Section 199A qualified business income (QBI) deduction.
REIT distributions are typically broken into:
A meaningful tax benefit specific to REIT ordinary dividends: under current law, individual taxpayers can generally deduct 20% of the ordinary REIT dividend income they receive (categorized as "Section 199A dividends," reported in Box 5 of Form 1099-DIV) before calculating tax on that income. This deduction is available regardless of whether the investor itemizes deductions, and it's one of the more significant tax advantages REIT ordinary dividends carry relative to a BDC's ordinary income distributions, which generally don't qualify for this deduction.
Because the large majority of publicly traded mREITs are organized and taxed as REITs, their distributions generally follow the same tax framework described above for equity REITs: predominantly ordinary income (eligible for the Section 199A 20% deduction), with smaller portions potentially characterized as capital gains or return of capital.
Key mREIT nuance: Because mREITs primarily generate net interest income rather than rental income with large depreciation deductions, mREIT distributions tend to have a smaller return-of-capital component than equity REIT distributions on average. Also, gains and losses on interest rate hedges can affect a mREIT's taxable income in ways that don't always track its GAAP or economic results, which is part of why the specific tax characterization of distributions can shift meaningfully from year to year.
A frequent point of confusion is whether investors will receive a Schedule K-1 (associated with partnerships and MLPs) rather than a standard Form 1099-DIV. The vast majority of publicly traded BDCs, REITs, and mREITs are organized as corporations for tax purposes and issue standard Form 1099-DIV, not a K-1. This is one practical advantage these structures have over MLPs: no K-1, no delayed filing season, and generally no state-tax filing complications in states where the investor doesn't otherwise have a filing obligation.
Because a substantial share of BDC, REIT, and mREIT distributions are taxed as ordinary income rather than at preferential rates, many investors find it tax-efficient to hold these investments in tax-advantaged accounts—such as a Traditional IRA, Roth IRA, or 401(k)—where the ordinary-income characterization doesn't trigger an annual tax bill. Income compounds tax-deferred (Traditional accounts) or tax-free (Roth accounts) until withdrawal, sidestepping the ordinary-income tax drag that would otherwise apply each year in a standard taxable brokerage account.
The tax treatment of BDC, REIT, and mREIT distributions is the part of these investments most easily overlooked when comparing headline yields, yet it can meaningfully change the actual after-tax return an investor takes home. The unifying theme across all three is that most of what they distribute is ordinary income, not preferentially taxed qualified dividends—a direct consequence of the same pass-through, no-corporate-tax structure that makes their high yields possible in the first place.
The relevant comparison is after-tax yield, not headline yield—and that comparison depends heavily on where the investment is held and the investor's own tax bracket.
