BDCs and mortgage REITs fit Roth accounts
BDCs and mortgage REITs can deliver double-digit yields, but the real investor question is not just how much income they pay — it is where that income is held and how much tax it attracts.
That matters because the structure that makes these vehicles attractive also makes their dividends expensive in taxable accounts. Business development companies and mortgage REITs generally must pass through at least 90% of taxable income to shareholders, which means they avoid corporate tax but push the tax bill onto investors, typically at ordinary-income rates rather than the lower rates applied to many stock dividends.
The distinction is not academic. AGNC Investment yields about 13.5%, Annaly Capital roughly 12.5%, Ares Capital around 9.5% and Main Street Capital about 5.5%, or roughly 7.5% including special dividends. For investors chasing income, those payouts can look compelling; for taxable accounts, they can also create a larger-than-expected April bill.
That is why the best place for these securities is often a Roth IRA or Roth 401(k), where after-tax contributions can grow and be withdrawn tax-free. Putting a BDC or mortgage REIT inside a Roth can turn a stream of ordinary-income distributions into tax-free retirement income, preserving more of the yield for the investor rather than the IRS.
By contrast, bank dividends are generally taxed more favorably, so if an investor has to choose where to shelter income, the higher-taxed BDC or REIT payout usually deserves the Roth space first. That portfolio placement issue is the core investment lesson: the same yield can have very different after-tax value depending on the account that owns it.
For investors, the message is simple. High yields from mortgage REITs and BDCs can still be useful, but only if the tax drag is managed deliberately. The next catalyst is not a product launch or earnings report, but year-end portfolio reallocation as savers decide which income assets belong in taxable accounts and which should be moved into Roths.
