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.
