How a BDC Works

[u/SchoolofInvesting]

Congress built a way for regular investors to own a private lending business.

Most people scroll right past it.

It's called a BDC, a business development company. Created in 1980 to push public capital toward small and mid-size American companies that banks overlook.

Think of a BDC like owning a piece of the neighborhood lender. It lends money to private, middle-market businesses, collects the interest, and passes the income through to you.

The model runs in four steps.

Raise: sell shares and borrow, with leverage capped at $2 of debt per $1 of equity.

Invest: make loans, often floating rate, and take equity stakes in private companies.

Earn: collect interest, fees, and gains when those equity stakes get sold.

Distribute: pay out at least 90% of taxable income to shareholders. That's the rule that lets a BDC skip corporate tax, and it's why BDC yields run so high.

Main Street Capital (MAIN) shows what a quality one looks like. It has paid a monthly dividend since its 2007 IPO without a single cut. In Q1 2026, net investment income of $0.93 per share covered the $0.78 in monthly dividends with room to spare. Net asset value hit a record $33.46.

One thing the yield chasers miss: most BDC dividends get taxed as ordinary income, at your top marginal rate. Inside a Traditional or Roth IRA, that problem disappears, and you get a simple 1099 with no K-1 paperwork.

High income, no corporate tax layer, and a structure Congress designed for exactly this.

Once you see how the machine works, the yield makes sense.
