How This $500K High-Yield Roth IRA Portfolio Generates $40K a Year Out of the IRS’s Reach

In the 24% federal bracket, a $500,000 income portfolio that pays about $39,870 a year sends roughly $9,569 to the IRS when the shares sit in a taxable account. Hold the same shares in a Roth IRA and the full amount stays with you.

Six High-Yielders Built for a Roth

This model portfolio puts a bigger share of capital in the steadier anchors and less in the riskiest payers. It combines two agency mortgage REITs, a business development company (BDC), a covered-call crude oil ETN, a midstream general partner, and an exploration and production company. Yields below are based on each security’s annualized forward distribution, using the share price as of October 8, 2026. The ETN is the exception and uses its trailing 12-month total because its payout changes every month.

AGNC has paid $0.12 per share every month for 75 consecutive months. Since REIT dividends count as ordinary, non-qualified income, this is precisely the kind of payout a Roth IRA is designed to shelter.

Annaly raised its quarterly dividend to $0.75 from $0.70. Earnings available for distribution of $0.79 per share covered the dividend for the ninth consecutive quarter. Like AGNC, it pays ordinary REIT income.

Prospect is a textbook example of BDC income, which is taxed largely at ordinary rates. It also carries the most risk here. The monthly payout fell to $0.035 from $0.045 in May 2026, and NAV per share slid to $5.71 from $6.56 year over year. It gets a small allocation for that reason.

USOI pays variable monthly distributions that are generally taxed as ordinary income. In 2026, those payments ranged from $0.4265 to $7.4743 per share. The yield is the highest in the portfolio, and so is the risk of NAV decay, which is why the position is capped at $10,000.

Plains GP pays $0.4175 per quarter, up from $0.38 in 2025. It gives the portfolio midstream exposure via a 1099-DIV rather than a K-1, simplifying tax reporting. Its distributions skew toward ordinary income and return of capital, and holding it in a Roth removes the need to track either.

APA pays $0.25 per quarter and is targeting at least 60% of free cash flow returned to shareholders in 2026. Most U.S. holders receive its dividend as qualified income, taxed at 0%, 15%, or 20%. That makes APA the least urgent of the six to hold in a Roth.

Roth Versus Taxable: $9,600 a Year in Your Pocket

The comparison below follows the series’ core formula: gross income times the bracket rate equals the tax cost. AGNC, Annaly, Prospect, and USOI pay ordinary income and produce $23,151 of the total. Because APA’s slice is taxed at lower qualified rates, the true drag on that piece is somewhat smaller than shown.

The IRS says the investment income rules in Publication 550 do not apply to investments held in IRAs. Inside a qualified Roth, every one of these monthly and quarterly checks lands untaxed.

Your Bracket Sets the Size of the Gap

The same $500,000 portfolio loses a very different share of its income depending on the bracket. Under the 2025 IRS schedule, the 24% bracket covered joint filers with taxable income from $206,701 to $394,600, and the 37% rate started at $751,601.

On this portfolio, a taxpayer in the 37% bracket gives up about $5,981 more each year than one in the 22% bracket. The higher your bracket, the more holding these stocks costs you each year.

Compounding Quietly Widens the Gap

The tables above treat the yearly tax saving as cash that piles up. In practice, money left inside a Roth gets reinvested tax-free. Assume the roughly $9,600 annual saving at the 24% bracket is reinvested at a conservative 4% a year, assuming flat share prices and no additional contributions:

• 10 years: about $114,900, compared with $95,700 uncompounded
• 20 years: about $284,900, compared with $191,400 uncompounded

At the 37% bracket, the 20-year figure rises to about $439,300. These numbers exclude any stock forecast and measure the cost of this income stream outside a Roth: income paid out, taxed, and gone before it can compound.

The income itself can change. AGNC’s monthly dividend was $0.20 in 2015, Prospect has cut its payout more than once, and USOI distributions move with crude oil volatility. If payouts shrink, the tax benefit shrinks with them. Investors should measure the delta against today’s dividends and avoid treating today’s yields as permanent.

Three Calculations to Run Before Your Next Filing

1. Price your current tax cost. If you hold a BDC or mortgage REIT in a taxable account, multiply last year’s ordinary dividends from your 1099-DIV by your marginal rate when you prepare your return. For a position sized like the AGNC and NLY slices here, the bracket table shows how quickly that cost adds up at 24%.
2. Work out the conversion math on these specific names. Compare the one-time tax cost of converting a position with its annual tax cost from the bracket table. Then decide whether the conversion bill outweighs a recurring delta.
3. Phase conversions by tax character. If you model a phased Roth conversion, start with the holdings that pay ordinary income (AGNC, Annaly, Prospect, and USOI) and leave qualified payers like APA for last, since they already get preferential rates.

Upcoming dates to watch include AGNC’s third-quarter earnings release and Prospect’s next monthly declaration. Both will indicate whether the income underpinning these calculations remains steady.
