A BDC fund, short for business development company, is a regulated investment vehicle that lends money to small and mid-sized private U.S. companies and passes the interest income through to shareholders. Federal tax law requires a BDC to distribute at least 90% of its taxable income each year, which is why yields on these funds typically run well above what you’d collect from a traditional bond fund or dividend stock. That same structure shapes the tax bill you’ll face on the income, the risks you take on as a shareholder, and the trade-offs worth understanding before you buy.
Congress created the BDC category through the Small Business Investment Incentive Act of 1980, amending the Investment Company Act of 1940 to let a new kind of fund raise capital from retail investors and channel it into private company debt and equity.1GovInfo. Small Business Investment Incentive Act of 1980 At least 70% of a BDC’s total assets have to sit in qualifying private company securities, small public companies with a market cap under $250 million, or a handful of other eligible holdings like cash and government securities.2Securities and Exchange Commission. Definition of Eligible Portfolio Company Under the Investment Company Act of 1940 BDCs are also expected to offer meaningful operational guidance to the companies they finance, either through advice from directors, officers, or affiliates, or by holding a controlling stake of 25% or more of voting stock.
What BDCs Actually Hold
The bulk of a BDC’s portfolio is interest-bearing loans to private companies. These aren’t publicly traded bonds. They’re directly negotiated credit agreements with individual borrowers, and the spread the BDC earns on every dollar lent is the foundation of the dividend you collect.
Senior Secured Debt
The most common holding is senior secured debt, which sits at the top of the borrower’s repayment priority. If a borrower defaults, senior secured lenders get paid first from the liquidated collateral. That makes it the lowest-risk slice of the portfolio, but “lowest risk” in private lending is still meaningfully riskier than investment-grade corporate bonds. The borrowers are private companies without the transparency, size, or credit ratings of publicly traded firms.
Subordinated and Mezzanine Debt
Some BDCs also hold subordinated debt, which ranks below senior claims in a default and pays a higher interest rate to compensate. Mezzanine financing blends debt with an equity sweetener, often warrants or conversion rights, giving the BDC upside if the borrower’s business grows. These positions carry substantially more risk than senior secured loans, and losses tend to be steeper when borrowers struggle.
Floating-Rate Loans
Nearly all BDC loans carry floating interest rates, typically benchmarked to the Secured Overnight Financing Rate (SOFR) plus a negotiated spread.3U.S. Securities and Exchange Commission. Press Release of Kayne Anderson BDC, Inc. – December 31, 2025 Financial Results When rates rise, BDC income rises with them because borrower rates reset automatically. The flip side matters just as much: when rates fall, income and dividends tend to fall too. Every 100 basis points of rate cuts translates to roughly a one-percentage-point drop in return on equity for a typical BDC.
Why the Yields Are So High
A BDC can elect to be treated as a Regulated Investment Company (RIC) under the Internal Revenue Code, which lets it avoid corporate-level income tax on earnings it distributes to shareholders. To keep that status, the fund has to pass two ongoing tests each year.4Office of the Law Revision Counsel. 26 U.S. Code 851 – Definition of Regulated Investment Company At least 90% of gross income has to come from dividends, interest, and investment gains. And at the end of every quarter, at least 50% of the fund’s assets have to be spread across cash, government securities, and positions where no single issuer represents more than 5% of total assets, with no more than 25% concentrated in any one issuer or related group.
To actually claim the dividends-paid deduction that zeros out entity-level tax, the BDC also has to distribute at least 90% of its investment company taxable income during the year.5Office of the Law Revision Counsel. 26 USC 852 – Taxation of Regulated Investment Companies and Their Shareholders Miss the income test, the diversification test, or the distribution requirement, and the BDC gets taxed as a regular corporation, which would roughly cut in half the income available to pass through to you.
There’s also a separate 4% excise tax on undistributed income unless the fund pays out at least 98% of ordinary income and 98.2% of capital gains each calendar year.6Office of the Law Revision Counsel. 26 U.S. Code 4982 – Excise Tax on Undistributed Income of Regulated Investment Companies That’s why most BDCs distribute essentially everything they earn. The tax code pushes payouts above even the 90% minimum.
Leverage adds another layer. Under Section 61 of the Investment Company Act, a BDC has to maintain an asset coverage ratio of at least 200%, meaning total assets must equal at least twice outstanding debt. That works out to a 1-to-1 debt-to-equity limit. The Small Business Credit Availability Act of 2018 gave BDCs the option to drop that floor to 150%, effectively doubling allowable leverage to 2-to-1.7Federal Register. Order Under Sections 6(c), 17(d), 38(a), and 57(i) of the Investment Company Act of 1940 and Rule 17d-1 Most publicly traded BDCs have adopted the 150% threshold. More leverage means more income to distribute, and it also means more risk.
How BDC Distributions Get Taxed
The high yields come with a more complicated tax picture than ordinary stock dividends. Because the fund passes through income without paying corporate tax, each dollar you receive gets taxed at the shareholder level based on the underlying source. Your Form 1099-DIV breaks the distribution into separate categories, and each one lands differently on your return.8Internal Revenue Service. Form 1099-DIV – Dividends and Distributions
Ordinary Income Dividends
The largest piece of most BDC distributions is ordinary income, generated from the interest the BDC collects on its loans. This gets taxed at your regular marginal income tax rate, which tops out at 37% for 2026.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 That’s the price of BDC yields. The headline dividend looks generous, but ordinary income tax takes a bigger bite than the preferential rates that apply to qualified dividends from regular stocks.
Qualified Dividends and Capital Gains
A smaller portion of distributions may qualify for long-term capital gains rates of 0%, 15%, or 20%, depending on your income. Qualified dividends come from the BDC’s equity holdings, and capital gain distributions come from profitable sales of assets held longer than a year. For 2026, the 20% rate applies at taxable income above $545,500 for single filers and $613,700 for married couples filing jointly.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 These favorable categories usually make up a small share of BDC distributions because the portfolio is overwhelmingly debt.
Return of Capital
Occasionally a BDC distributes more than its current earnings. The excess shows up on your 1099-DIV as a nondividend distribution, commonly called return of capital. It isn’t taxable when you receive it. Instead, it reduces your cost basis in the shares. If your basis drops to zero and you keep receiving return of capital, the excess gets taxed as a capital gain. Return of capital isn’t automatically a red flag, but a persistent pattern can signal that the fund is paying out more than it’s actually earning, which warrants a closer look at its financial health.
Section 199A Treatment
The One Big Beautiful Bill Act, signed into law on July 4, 2025, made the Section 199A qualified business income deduction permanent.10Internal Revenue Service. One, Big, Beautiful Bill Provisions Section 199A allows a 20% deduction on certain pass-through income and has historically applied to qualified REIT dividends but generally not to BDC dividends. If Section 199A ever extends to BDC ordinary dividends, it would drop the effective top rate on those distributions from 37% to roughly 29.6%. Check Box 5 on your 1099-DIV for any Section 199A dividend amounts and confirm current eligibility with a tax professional.
How to Buy a BDC
You can invest in BDCs through two channels, and the differences run deeper than where you place the trade.
Publicly Traded BDCs
These are listed on major exchanges like the NYSE and trade throughout the day like any stock. Liquidity is high. The trade-off is price volatility: shares frequently trade at a discount or premium to net asset value (NAV). During market stress, discounts of 15% to 25% below NAV are not uncommon, which means you could be selling a dollar of underlying assets for 75 to 85 cents if you have to exit at the wrong time. In calmer markets some BDCs trade at modest premiums.
Non-Traded BDCs
Non-traded BDCs are sold through broker-dealers and aren’t listed on any exchange. Shares are typically priced at NAV, which insulates you from the market-sentiment swings publicly traded BDCs go through. That stability comes at the cost of liquidity. Exit options are usually limited to quarterly share repurchase programs, and those programs can be reduced or suspended at the fund’s discretion. If you need your money back on short notice, you may not be able to get it. FINRA has flagged non-traded BDCs as a product requiring heightened due diligence from brokers who recommend them.
Non-traded BDCs often require accredited investor status. Under SEC rules, that means individual income above $200,000 in each of the two most recent years (or $300,000 jointly with a spouse), or a net worth exceeding $1 million excluding your primary residence.11eCFR. 17 CFR 230.501 – Definitions and Terms Used in Regulation D The primary residence exclusion cuts both ways: the home’s value doesn’t count as an asset, and the mortgage doesn’t count as a liability unless the balance exceeds fair market value.
Fees
BDC fees follow a two-layer model borrowed from private equity. Base management fees run 1% to 2% of gross assets, with newer BDC launches trending toward 1.5% to 1.75%. On top of that sits an incentive fee, typically 20% of net investment income above a hurdle rate plus 20% of realized capital gains net of losses. Some BDCs have negotiated the incentive fee down to 17.5%, but 20% is still the industry standard.
Non-traded BDCs frequently layer on upfront sales charges that publicly traded funds avoid. These can run several percentage points of your initial investment. A BDC yielding 11% with a 2% management fee, a 20% incentive fee, and a 3% sales load delivers meaningfully less net income than the headline suggests, so total cost matters more than the quoted yield.
The Main Risks
The yields are real, and so are the risks. BDCs lend to borrowers that banks either won’t touch or won’t fully fund, and that credit profile shows up in default rates and NAV volatility beyond what you’d see in an investment-grade bond fund.
Credit and Default Risk
Portfolio companies are private, often highly leveraged, and lack the financial cushion of larger public firms. When the economy softens, these borrowers are among the first to struggle with debt service. Defaults can drive sharp NAV declines. During severe stress periods, individual BDCs have seen NAV drops of 50% or more, and the broader BDC sector can sell off 20% to 25% in a matter of weeks.
Interest Rate Sensitivity
The floating-rate structure works both ways. Rising rates lift income, but a sustained rate-cutting cycle compresses the spread between what BDCs earn on their loans and what they pay on their own borrowings. Dividends tend to follow rates down, which can disappoint investors who bought in during a high-rate environment. Some loans include interest rate floors, but those protections are limited and not universal.
Leverage Amplification
Most BDCs operate at or near the 2-to-1 debt-to-equity limit. Leverage amplifies returns in good times and magnifies losses in bad ones. A 10% decline in the value of a BDC’s loan portfolio translates to roughly a 20% hit to equity at 2-to-1 leverage. That math explains why BDC share prices can move more sharply than you’d expect from a fund that holds debt rather than equity.
NAV Discounts on Publicly Traded Shares
Even if the underlying loan portfolio performs well, publicly traded BDC shares can trade at a persistent discount to NAV during periods of market pessimism. You’re exposed to two layers of risk: the credit quality of the portfolio and the market’s willingness to pay fair value for it. Selling during a discount period locks in a loss that has nothing to do with the borrowers’ actual repayment performance.
Liquidity Risk in Non-Traded BDCs
Non-traded BDC shares can’t be sold on an exchange, and the quarterly repurchase programs that provide the exit are subject to the fund’s discretion. In a downturn, the fund may limit or suspend repurchases entirely, leaving you holding an illiquid position with no clear path to cash. The situations where you most want to exit are exactly when the fund is least likely to buy your shares back.
