Brokerage Account Taxes: Dividends, Capital Gains Explained
Brokerage account taxes depend less on how much your account grew than on what kind of income it produced. Dividends, interest and sales are taxed in different ways, and in a taxable account the bill can arrive even in a year when you never withdraw a penny.
Key takeaways
- Unrealized gains are not taxed; gains are taxed on sale, dividends and interest when received.
- Qualified dividends and long-term gains use 0%, 15% or 20% rates; other brokerage income uses ordinary rates.
- For 2026, the 0% long-term rate covers taxable income up to $49,450 single or $98,900 jointly.
- Reinvested dividends are still taxable, and a wash sale can disallow a loss near a repurchase.
- 1099-DIV reports dividends, 1099-B reports sales, and 1099-INT reports interest.
A taxable account is taxed as income arrives
A brokerage account is not a retirement account. Inside an IRA or 401(k), dividends, interest and gains are generally sheltered until withdrawal. In a taxable account there is no such shelter, so income is taxed in the year it is received or realized. See our guide to how to start investing money for account and fund choices. A rise in price alone is not taxed; the tax event is the sale, while dividends and interest are income when paid, whether you take cash or reinvest.
Dividends: qualified versus ordinary
Dividends are distributions of company earnings. Ordinary dividends are taxed at ordinary income rates, from 10% to 37% for 2026. Qualified dividends are taxed at the lower capital gains rates of 0%, 15% or 20%, and the payer must identify which ordinary dividends are also qualified on Form 1099-DIV. Qualification is not automatic: for common stock, you generally must have held the shares for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date, or at least 61 counted days.
Capital gains: the holding period decides the rate
When you sell for more than your adjusted basis, the difference is a capital gain. A gain is long-term if you held the asset for more than one year, and short-term if you held it for one year or less. Short-term gains are taxed as ordinary income, up to 37%. Long-term gains get the preferential 0%, 15% or 20% rates, decided by total taxable income and filing status. For 2026, under Revenue Procedure 2025-32, the 0% rate covers taxable income up to $49,450 single and $98,900 jointly, and the 15% rate runs up to $545,500 single and $613,700 jointly, with 20% above. Gains stack on ordinary income. Higher earners may also owe 3.8% net investment income tax above $200,000 single or $250,000 jointly.
| Income type | How it is taxed | 2026 federal rate |
|---|---|---|
| Qualified dividends | Capital gains rates | 0%, 15% or 20% |
| Ordinary dividends | Ordinary income rates | 10% to 37% |
| Long-term gains | Held more than one year | 0%, 15% or 20% |
| Short-term gains | Held one year or less | Ordinary rates, up to 37% |
| Interest | Ordinary income rates | 10% to 37% |
| Return of capital | Lowers basis, not taxed at once | Gain once basis reaches zero |
Interest, fund distributions and return of capital
Interest from bonds and money market funds is taxed as ordinary income and never earns the preferential rates. A fund can distribute capital gains even when you sold nothing yourself, because the fund sold holdings inside the portfolio, and those distributions are generally treated as long-term gains on Form 1099-DIV. Some distributions are instead a return of capital, a return of your own money rather than earnings. That is not taxed immediately; it lowers your cost basis, raising the gain when you sell.
Worked example: the same $5,000 profit, two tax bills
Suppose you sell shares for a $5,000 profit. Held for eight months, the gain is short-term: at an ordinary rate of 22%, federal tax is $5,000 x 22% = $1,100. Held for more than a year, with taxable income putting the gain in the 15% long-term band, federal tax is $5,000 x 15% = $750. The difference is $350, before state tax or net investment income tax. This is illustrative maths only: your rate depends on total taxable income and filing status.
Wash sales and tax-loss harvesting
Losses first offset capital gains; if losses exceed gains, up to $3,000 a year ($1,500 if married filing separately) can offset ordinary income, and the remainder carries forward. That is tax-loss harvesting. The trap is the wash sale rule: selling at a loss and buying the same or a substantially identical security within 30 days before or after the sale disallows the loss for that year. The disallowed loss is usually added to the replacement shares basis, but purchases by a spouse or inside an IRA can erase it permanently.
Your 1099 forms, and what to check
After year-end your broker sends a consolidated 1099 package, usually by mid-February, and reports the same figures to the IRS, so the return should match the forms. Form 1099-DIV reports dividends: box 1a is total ordinary dividends, box 1b the qualified portion already included in box 1a, so do not add it twice, and box 2a shows capital gain distributions. Form 1099-B reports sales and flags wash sales; Form 1099-INT reports interest. No tax is withheld from brokerage income, so a big gain year can mean estimated payments.
Placement and a short year-end checklist
Where you hold an investment can matter as much as what you hold. Income taxed at ordinary rates, such as bond interest, costs the most in a taxable account, so if you have both taxable and retirement accounts, those holdings are the natural candidates for the sheltered account. Broad stock index funds, which tend to pay mostly qualified dividends, are comparatively cheap to hold taxable. Before filing, reconcile the 1099 package and check for a December wash sale completed in January. State taxes are a second layer.
