A $600,000 Dividend Portfolio Has a $52,900 Tax Problem. Here’s the Roth Solution

At the 24% bracket, a $600,000 portfolio split equally across six high-yield dividend stocks generates about $29,400 a year, and roughly $5,300 of it goes to the IRS before anything gets reinvested. Inside a Roth IRA, you keep that $5,300.

The tax rules work like this. Qualified dividends are taxed at capital gains rates when held outside tax-advantaged accounts: 15% for most taxpayers through the 32% bracket and 20% at the top. REIT payouts are mostly ordinary income taxed at your marginal rate, though a deduction of 20% of qualified REIT dividends under Section 199A can reduce that bill. Qualified Roth distributions, taken after the 5-year period and at or after age 59½, carry no tax liability. The math below uses the full marginal rate to the REIT payouts.

Six Stocks, Two Accounts, $5,300 Gap at 24%

Each stock gets $100,000. The yields shown are each company’s current quarterly dividend, annualized, divided by its latest share price.

That works out to $5,300 a year in Roth advantage and $52,900 over 10 years before any growth. The two REITs produce $9,700 of the income but account for $2,300 of the tax.

• Simon Property Group (NYSE:SPG): 4.47% yield. These payouts are ordinary income, so Simon is the top Roth candidate here. The $2.25 quarterly dividend, up 4.7%, takes about 68% of the middle of FFO guidance of $13.20 to $13.30.
• Crown Castle (NYSE:CCI): 5.23% yield, also paid as ordinary REIT income. Coverage is tight, at roughly 93% of the $4.59 AFFO guidance. Crown Castle cut its payout to $1.0625 from $1.565 in 2025, though management now calls it “sacrosanct.”
• United Parcel Service (NYSE:UPS | UPS Price Prediction): 6.79% yield, the highest qualified payout in the group. The $6.56 annual dividend takes about 91% of the roughly $7.22 adjusted EPS that UPS has guided for this year.
• LyondellBasell (NYSE:LYB): 4.47% yield on the reset rate. The quarterly dividend fell to $0.69 from $1.37, and trailing GAAP EPS is -$0.83. That shows a sheltered yield can still shrink.
• Bristol Myers Squibb (NYSE:BMY): 4.13% yield, with the best coverage of the six at about 37% of the middle of EPS guidance. Second-quarter operating cash flow came to $3.4 billion.

Franklin Resources (NYSE:BEN) fills out the portfolio with a 4.34% yield. Its $0.33 quarterly dividend took about 46% of the $0.72 in adjusted EPS from the latest quarter.

Higher Brackets Widen the Gap Fast

At 37%, the rate on qualified dividends also rises to 20%, so all six positions cost more. For a single taxpayers, the 24% bracket uses to taxable income of $103,351 to $197,300 under the 2025 tables.

Compounding Makes the Annual Gap Far Larger

If you reinvest the annual $5,300 at a conservative 4%, and there is no price appreciation, the Roth benefit reaches about $63,500 after 10 years and $157,500 after 20. Holding this income in a taxable account carries a permanent cost, and it grows every year the positions stay there. Your cheapest moment to shift these holdings into a Roth is usually the quiet period between a last paycheck and the first RMD, which is the whole subject of our free Roth window guide.

Three Moves to Make Before Your Next Tax Filing

1. For every REIT or BDC you hold outside a tax-advantaged account, multiply its income by your marginal rate to see what it costs you each year.
2. Before you decide a conversion costs too much, run the Roth conversion math on Simon and Crown Castle and weigh the one-time tax bill against the annual income gap.
3. Consider a staged conversion that moves the ordinary-income payers first, then the qualified payers, starting with the ones that cover their dividends best.
