Best Online Brokers for BDC Investing (2026)
Published: July 22, 2026 · Last updated: July 22, 2026
Business Development Companies (BDCs) trade on the same exchanges as every other publicly listed US equity, so technically any online broker that lets you buy NYSE or NASDAQ stocks will let you own ARCC, MAIN, BXSL, or any other BDC. That does not mean every broker is equally well-suited to a BDC income strategy. For investors building a BDC portfolio, the differences that actually matter day-to-day are:
- Fractional share support — BDC share prices cluster in the $5 to $40 range, and most yield-focused investors want to deploy fixed dollar amounts (often monthly). Brokers that allow fractional BDC purchases let you reinvest distributions to the dollar instead of being forced to round to whole shares.
- DRIP availability — automatic dividend reinvestment is what compounds BDC income, and not every broker offers DRIP on every BDC ticker.
- Fee schedule for low-priced stocks — most modern brokers are commission-free; the differentiator is margin rates, options on BDCs (covered calls are common income overlays), and pass-through fees like ORF and SEC Section 31.
- Income and distribution tracking — a broker that surfaces ex-div, pay-date, and distribution-tax classification (ordinary vs. return-of-capital) on the holdings screen saves BDC investors time at tax season.
- IRA and tax-advantaged eligibility — taxable BDC distributions are taxed at ordinary income rates by default, so holding BDCs inside an IRA is one of the most efficient placements. You want a broker that supports IRAs cleanly.
Based on those criteria, the two platforms below are the ones we recommend for retail BDC investors. Both are US regulated broker-dealers, both list every publicly traded BDC, and both are linked through internal tracking paths on this site (see our Affiliate Disclosure).

How to Choose Between the Two
If your goal is straightforward — buy a handful of high-quality BDCs like ARCC, MAIN, or BXSL, collect monthly or quarterly distributions, and reinvest them — eToro is the better fit. Fractional shares from $10 mean you can deploy every dollar of every distribution, and the 0% commission on US stocks keeps drag low. Note that eToro does not offer automatic DRIP; distributions arrive as cash, so you will need to set up recurring buy orders or reinvest manually to keep compounding. Also, eToro does not offer IRA accounts — only taxable brokerage — which matters because BDC distributions are taxed as ordinary income, making tax-advantaged accounts especially efficient. The platform is built for retail investors who want to keep things simple.
If you want to run BDCs as a serious income strategy — writing covered calls on MAIN, using modest margin to lever senior-secured BDC holdings like BXSL, or hedging NAV exposure with options — IBKR is the better fit. Its margin rates are consistently 2 to 4 percentage points below retail competitors, the options analytics in TWS are institutional-grade, and asset-coverage data is easier to layer in alongside the BDC's NAV.
There is nothing wrong with holding both. Many income investors keep a simple long-only BDC book at eToro for the fractional reinvestment, and a separate IBKR IRA for the tax-sheltered compounding — getting the best of both platforms.
What to Set Up After You Open the Account
Once your brokerage account is funded and you have placed your first BDC order, three quick settings dramatically improve the experience for an income-focused strategy:
- Set up automatic reinvestment. On IBKR, enable DRIP on each BDC position so distributions automatically buy more shares. On eToro, DRIP is not available — dividends arrive as cash, so set up recurring buy orders to redeploy them regularly. Either way, the goal is to keep every dollar compounding.
- Track ex-div and pay dates in the broker's calendar tool. BDC dividends cluster at quarter-end, so knowing when the cash will settle in your account lets you plan reinvestment or withdrawals ahead of time.
- If you own BDCs in a taxable account, turn on distribution tax classification. BDC distributions are typically split between ordinary income, capital gains, and return of capital — each taxed differently. A broker that surfaces this classification (both eToro and IBKR do) saves real money at tax time.
Frequently Asked Questions
Can I buy BDCs on any brokerage account?
Yes. BDCs are publicly traded equities listed on NYSE and NASDAQ, so any brokerage that offers US stock trading can buy and sell them. The difference between brokers is fees, fractional availability, distribution tracking, and IRA eligibility — not whether you can trade them at all.
Do BDCs pay dividends monthly or quarterly?
Most pay quarterly. A subset — Main Street Capital (MAIN), Prospect Capital (PSEC), and Gladstone Investment (GAIN) among others — pays monthly. Some BDCs supplement their regular distribution with a year-end supplemental dividend. A broker that tracks ex-div and pay dates clearly helps you project monthly income.
What is the minimum to start investing in BDCs?
On eToro, fractional shares let you start with as little as $10. On a whole-share broker, you need enough to buy at least one share of the BDC you want, typically between $10 and $40 per share for the most-traded BDCs.
Next Steps
Once your brokerage account is open and funded, the natural next step is to pick which BDCs to buy. Our BDC primer, live dividend table, and largest-BDCs ranking are the three most useful starting points on this site. If you want a quick shortlist, see Best BDCs for Income Investors.
