An $800,000 Portfolio Pays Nearly $3,800 a Month. How Much Would Taxes Take?
Where you hold a dividend portfolio matters almost as much as what you hold, and for one mix of REITs and a BDC generating nearly $45,000 a year, the difference between account types could quietly reshape your retirement math.
At the 24% federal bracket, an $800,000 portfolio split evenly across three monthly and quarterly payers produces about $45,384 in annual dividends. Held in a taxable account, roughly $10,892 goes to the IRS each year. In 2026, the 24% rate starts at taxable income above $105,700 for single filers and $211,400 for married couples filing jointly.
Why REITs and BDCs Take the Biggest Tax Hit
Payouts from REITs and business development companies are mostly non-qualified dividends, so a regular account taxes them as ordinary income. Under 26 U.S.C. § 1(h)(11)(D)(iii), the tax code limits qualified-dividend treatment for dividends from REITs and regulated investment companies. REIT shareholders can deduct 20% of qualified REIT dividends under 26 U.S.C. § 199A(b)(1)(B). That deduction narrows the gap on the two REITs here, but the gap remains significant. The math below uses the full bracket rate.
A Roth keeps $45,384 a Year. A Taxable Account Keeps $34,492
Each position gets about $266,667. Current share prices and forward annualized dividends set the yields.
| Stock | Yield | Gross Income | Tax at 24% | Taxable Net | Roth Net |
|---|---|---|---|---|---|
| Main Street Capital (NYSE:MAIN | MAIN Price Prediction) | 6.0% | $16,000 | $3,840 | $12,160 | $16,000 |
| NNN REIT (NYSE:NNN) | 6.09% | $16,241 | $3,898 | $12,343 | $16,241 |
| Agree Realty (NYSE:ADC) | 4.93% | $13,143 | $3,154 | $9,989 | $13,143 |
| Total | $45,384 | $10,892 | $34,492 | $45,384 |
The Roth comes out ahead by about $10,892 a year, or $108,920 over 10 years with no growth assumed.
- Main Street Capital: The yield uses a $3.18 forward regular dividend and a $53 share price. Special payouts brought trailing 12-month dividends to $4.33, so actual income, and actual tax drag, can run above the table. Safety read: Q2 distributable net investment income (DNII) before taxes came in at $1.08 per share. NAV hit a record $33.92, non-accruals were 1.1% of fair value, and leverage stood at 0.69x. Management expects Q3 DNII of at least $0.97 per share.
- NNN REIT: The yield uses a $2.48 annualized dividend and a $40.72 share price. As the highest yielder of the three, it carries the largest tax bill. Safety read: the AFFO payout ratio is 69%, occupancy is 99.1%, and 2026 marks the company’s 37th consecutive annual dividend increase.
- Agree Realty: The yield uses a $3.252 forward dividend and a $65.98 share price. The monthly payout just rose to $0.271. Safety read: Q3 payout was approximately 69% of AFFO, occupancy hit a record 99.8%, and the company has no material debt maturities until 2028.
How Much Your Bracket Adds to the Roth Advantage
| Bracket | Taxable Net | Roth Net | The Yearly Roth Advantage |
|---|---|---|---|
| 22% | $35,400 | $45,384 | $9,984 |
| 24% | $34,492 | $45,384 | $10,892 |
| 32% | $30,861 | $45,384 | $14,523 |
| 37% | $28,592 | $45,384 | $16,792 |
A household in the top bracket gives up close to $16,792 a year on these three stocks alone. The higher the bracket, the more each year of holding these stocks costs (the quiet years between your last paycheck and your first RMD are often the cheapest time to move these positions into a Roth, which is the whole subject of our free Roth Window guide).
Compounding Turns $10,892 a Year Into $324,343
Reinvest the annual $10,892 difference at 4%, and it reaches about $130,771 after 10 years, compared with $108,920 without reinvestment. After 20 years, it reaches roughly $324,343, compared with $217,840. These figures leave out dividend increases and price changes. They show what it costs to hold these three positions in a taxable account over time.
Three Steps Before Your Next Tax Filing
- Pull your 1099-DIV for any BDC or REIT held in a taxable account and multiply its ordinary dividends by the rate on your top bracket. Your annual tax cost is that figure.
- Run Roth location math on Main Street Capital and NNN REIT first. They yield the most here, so they gain the most from tax-free location.
- Model a phased conversion over several tax years, set so each year’s converted amount keeps you inside your current bracket.
