At the 24% federal bracket, a $500,000 portfolio of high-yield REITs, BDCs and mortgage REITs generating roughly $35,000 in annual ordinary-income distributions hands the IRS $8,400 every year. That tax bill never appears on a brokerage statement, but it shows up in net income, in reinvestment power and in the slope of every long-term compounding curve.
The five names below are the textbook reason asset location exists.
The Tax Delta: Roth Versus Taxable at the 24% Bracket
Assume an equal-weighted $500,000 portfolio, $100,000 in each name, using current yields:
- Realty Income (NYSE:O | O Price Prediction): yield 5%, generating roughly $5,270 per $100,000. REIT distributions are classified as ordinary income, so every one of the 12 monthly payments is fully taxable in a brokerage account.
- AGNC Investment (NASDAQ:AGNC): yield 14%, generating roughly $13,700 per $100,000. Agency mREIT dividends are taxed as ordinary income, not qualified dividends, which is why a double-digit yield bleeds the most in a taxable account.
- Main Street Capital (NYSE:MAIN): yield 6%, generating roughly $5,970 per $100,000 before the $0.30 quarterly supplemental. BDC distributions are ordinary income; supplementals magnify the drag.
- Ares Capital (NASDAQ:ARCC): yield 10%, generating roughly $10,200 per $100,000. The largest publicly traded BDC has paid 48 cents quarterly for eight consecutive quarters, all taxed at ordinary rates.
- PIMCO Dynamic Income Fund (NYSE:PDI): closed-end fund trading near $16.65. Distributions blend ordinary income and return of capital, with the ordinary-income slice taxed at full marginal rates outside a Roth.
Across the four names with verified current yields, the $400,000 allocation throws off roughly $35,140 in gross annual income. At 24%, the taxable account nets about $26,706. The Roth nets the full $35,140. Annual delta: roughly $8,434. Ten-year delta with no reinvestment: roughly $84,340. PDI’s ordinary-income component adds to that gap.
The Bracket Multiplier
On the same $35,140 of gross ordinary-income distributions:
| Bracket | Annual Tax in Taxable | Net in Taxable | Annual Roth Advantage |
|---|---|---|---|
| 22% | ~$7,731 | ~$27,409 | ~$7,731 |
| 24% | ~$8,434 | ~$26,706 | ~$8,434 |
| 32% | ~$11,245 | ~$23,895 | ~$11,245 |
| 37% | ~$13,002 | ~$22,138 | ~$13,002 |
The 37% bracket kicks in above $640,600 for single filers and $768,700 for married filing jointly in 2026. A reader at that bracket loses more than a third of every BDC and mREIT distribution to the IRS the moment it hits a brokerage account.
The Insight Most Readers Miss
The $8,434 annual gap at 24% compounds year after year. Reinvested back into the same yield basket and compounded at a conservative 5% reinvestment rate, the Roth advantage stacks into roughly $106,000 over 10 years and roughly $279,000 over 20 years on this single $500,000 portfolio. No price appreciation assumed. No additional contributions. The compounding is purely the recaptured tax. AGNC’s 32% one-year total move and Realty Income’s 12% one-year gain are incremental returns on top of that tax recapture.
What to Do
Three concrete steps for readers holding any of these five names in a taxable account:
- Pull the 1099-DIV from the most recent tax year for O, AGNC, MAIN, ARCC or PDI and identify how much of each distribution sat in Box 1a (ordinary) versus Box 1b (qualified). The ordinary slice is the line that benefits most from Roth placement.
- Run the conversion math on the specific positions named here before assuming the conversion tax outweighs the long-term income delta. At 24%, a $100,000 AGNC position pays for its own conversion cost in roughly three years of recaptured tax drag.
- If the highest-yielding names sit in the taxable account and lower-yielding qualified-dividend payers sit in the Roth, model a swap. Asset location is the lever that matters here.
