ARCC yields 9.71% and MPLX 7.35%, but both lose up to 37 cents per dollar to taxes outside a Roth. The $9,600 annual savings at 24% compounds tax-free.
A portfolio of BDCs, REITs, and MLPs paying $50,000 a year in distributions loses $12,000 to the IRS at the 24% federal bracket when held in a taxable account. Those payouts hit as ordinary income, not qualified dividends, making the tax drag a fixed cost of holding them outside a retirement wrapper.
Five names share that trait. Their distributions land largely as ordinary income. Yields are pulled from current market data.
Main Street Capital (NYSE:MAIN), a business development company, yields 5.29% with a $0.265 monthly base plus recurring $0.30 supplemental distributions. BDC income flows through as ordinary income.
Realty Income (NYSE:O), a net-lease real estate investment trust, yields 5.12% and has now delivered its 115th consecutive quarterly dividend increase. REIT distributions are largely non-qualified.
Ares Capital (NASDAQ:ARCC), the largest publicly traded BDC, yields 9.71% with a $0.48 quarterly dividend taxed at your marginal rate outside a Roth. AlphaScala's score is unavailable for ARCC, which carries an Unscored label in the Financial Services sector.
MPLX LP (NYSE:MPLX), a midstream master limited partnership, yields 7.35% after a $1.0765 quarterly distribution. AlphaScala assigns MPLX a Moderate Alpha Score of 65 in the Energy sector. Note the UBTI $1,000 threshold before sizing large MLP positions in a Roth.
Enterprise Products Partners (NYSE:EPD), another midstream MLP, yields 5.74% with a $0.56 quarterly distribution and the same UBTI caveat.
Run the math. A $500,000 position sized to an 8% blended yield generates $40,000 in gross annual income. Inside a taxable account at 24%, that income nets $30,400 after tax. Inside a Roth, the same portfolio nets the full $40,000. The Roth advantage is $9,600 per year. Held for a decade with no additional contributions or reinvestment, that is nearly $100,000 of income the taxable investor never sees.
The Roth advantage scales directly with your marginal rate. A reader in the top bracket forfeits more than a third of every distribution from ARCC, MAIN, and the MLP names when they sit in a taxable account.
Total returns underscore the case. MAIN is up 104.93% over five years. ARCC is up 61.85%. MPLX has advanced 226.51% and EPD 151.18% over the same window. High-yield names can still deliver meaningful capital appreciation.
If you hold any BDC or mortgage REIT in a taxable account, calculate your annual tax drag at your marginal bracket before your next tax filing, then compare it to the Roth conversion cost on that specific position. Model a phased Roth conversion starting with the ordinary-income payers on this list: ARCC and MAIN first, then O, before any qualified-dividend names.
For MLPs like MPLX and EPD, run the UBTI numbers against the $1,000 threshold inside your Roth before sizing the position, so the shelter does not create a Form 990-T filing you did not plan for.
