How Much More Dividend Income a Roth IRA Keeps on a Half-Million-Dollar Portfolio
Six dividend stocks in a $500,000 portfolio sound like a solid income plan, but where you hold them decides how much of that income you actually keep, and the difference compounds into a number most investors never calculate.
At the 24% bracket, a $500,000 portfolio split across six dividend payers sends about $3,072 a year to the IRS. In a Roth IRA, the same dividends arrive untaxed.
Dollars Kept: Roth Versus Taxable on $500,000
Each stock gets an equal stake of about $83,333. Yield is each company’s annualized forward dividend divided by its October 9 price. Most filers in this bracket pay the 15% capital gains rate on qualified dividends (IRS Topic 409). REIT distributions generally face the full 24% income rate.
| Stock | Yield | Annual Income | Tax Treatment | Taxable Cost at 24% |
|---|---|---|---|---|
| Texas Instruments (NASDAQ:TXN | TXN Price Prediction) | 2.11% | $1,758 | Qualified | $264 |
| JPMorgan Chase (NYSE:JPM) | 1.98% | $1,651 | Qualified | $248 |
| Pfizer (NYSE:PFE) | 6.11% | $5,090 | Qualified | $763 |
| Coca-Cola (NYSE:KO) | 2.40% | $2,004 | Qualified | $301 |
| Prologis (NYSE:PLD) | 3.31% | $2,761 | Ordinary (REIT) | $663 |
| Public Storage (NYSE:PSA) | 4.17% | $3,474 | Ordinary (REIT) | $834 |
Inside a Roth, the portfolio’s $16,739 of gross income stays whole. Outside that shelter, it shrinks to $13,667. That leaves about $3,070 more each year in the Roth, or $30,720 over 10 years with no growth or new money assumed. To qualify, Roth withdrawals have to come after the five-year period and on or after age 59½ (IRS Publication 590-B).
The REITs account for most of the gap. Prologis and Public Storage produce 37% of the income but 49% of the tax bill. Public Storage has paid $3 quarterly since 2023 and reports about $600 million of annual free cash flow. Prologis raised its payout to $1.07 from $1.01. Pfizer is the largest qualified-dividend payer here, with its $0.43 quarterly dividend unchanged since early 2025. Texas Instruments, JPMorgan and Coca-Cola recently raised their dividends to $1.52, $1.65 and $0.53. These three gain the least from Roth placement. Some REIT investors can also claim the 199A write-off, which lowers the effective rate on REIT income.
How Your Bracket Changes the Gap
In tax year 2026, single filers pay the 24% rate on income above $105,700 ($211,400 joint). Filers in the 37% bracket also move up to the 20% qualified rate.
| Bracket | Taxable Net Income | The Roth’s yearly edge |
|---|---|---|
| 22% | $13,791 | $2,947 |
| 24% | $13,667 | $3,072 |
| 32% | $13,168 | $3,571 |
| 37% | $12,331 | $4,408 |
Compounding Lifts the 20-Year Gap to $91,000
The $3,072 annual gap at the 24% bracket keeps growing if each year’s saved tax is reinvested at a conservative 4%. Over 10 years it reaches $36,883. Over 20 years it reaches $91,478, compared with $61,440 without reinvestment. No share price growth is assumed. This is what holding these six stocks outside a Roth costs over time.
Roth Limits That Shape the Plan
Roth contributions have annual caps, and income limits can reduce or block direct contributions (IRS Publication 590-A). Investors usually build a $500,000 Roth over many years or by converting a traditional IRA (Publication 17), and conversions trigger income tax. The quiet years between a final paycheck and the first required withdrawal are often when conversions are cheapest, a window we sized up in a free Roth guide. In practice, the useful question is which holdings belong in the Roth space you already have.
What to Do Before Your Next Filing
- If you hold REITs outside a retirement account, use last year’s 1099-DIV to separate ordinary dividends from qualified ones, then work out what each costs at your bracket.
- Before deciding a Roth conversion costs too much, compare the tax on the conversion with the 20-year income gap for your own holdings.
- If your Roth holds low-yield growth stocks while REITs are held outside it, model swapping them so the ordinary-income payers move into the Roth first.
