Tax Cost Hiding Inside Your Brokerage Account
At the 24% federal ordinary-income bracket, a portfolio throwing off $50,000 a year in non-qualified dividend income hands $12,000 straight to the IRS every filing season. That is the annual price of holding high-yield BDCs, REITs, and MLPs in a taxable account when the payouts hit your return as ordinary income rather than as qualified dividends.
Same Five Stocks, Two Very Different Outcomes
The five names below share one trait that makes Roth placement especially valuable: their distributions land largely as ordinary income. Yields are pulled live from current market data.
- Main Street Capital (NYSE:MAIN | MAIN Price Prediction), a business development company (BDC), 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 (REIT), 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 that is taxed at your marginal rate outside a Roth.
- MPLX LP (NYSE:MPLX), a midstream master limited partnership (MLP), yields 7.35% after a $1.0765 quarterly distribution. 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.
Anchor Comparison: $500K at the 24% Bracket
Use the platform math from the series framework. 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, every year. Held for a decade with no additional contributions or reinvestment, that is nearly $100,000 of income the taxable investor never sees.
Bracket Multiplier: Higher Earners Bleed Faster
The Roth advantage scales directly with your marginal rate. The higher your bracket, the more of every distribution the taxable account gives up.
| Federal Bracket | Share of Every Dividend Dollar Lost in Taxable | Share Retained Inside Roth |
|---|---|---|
| 22% | 22 cents | 100 cents |
| 24% | 24 cents | 100 cents |
| 32% | 32 cents | 100 cents |
| 37% | 37 cents | 100 cents |
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. That is the case for putting the highest-yielding, ordinary-income payers in the Roth first, and it is the same logic behind our free guide on turning a mid six-figure balance into a monthly paycheck, here.
Insight Most Readers Miss: The Compounding Layer
The Roth advantage compounds. It is the annual tax leakage reinvested tax-free for as long as you own the position. Anchor back to the $9,600 annual delta at 24%. Reinvested every year at a conservative rate that matches the portfolio’s blended yield, the ten-year and twenty-year gap widens well beyond the sum of the annual savings. Nothing about that requires forecasting stock appreciation. It is the same distribution stream, taxed once or not at all, compounding on itself.
Total returns underscore why these five are worth the Roth slot in the first place. 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.
What to Do Before Your Next Contribution
- 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.
