How Investment Income Is Taxed in the US: Capital Gains, Dividends, and Interest

Unlike some countries that exempt stock sale profits from tax entirely, the US taxes investment income — but not all investment income the same way. How much you owe depends on what the income is (a sale, a dividend, or interest) and, for stock sales, how long you held the position. Here's how each type is actually taxed in 2026.

Short-Term vs Long-Term Capital Gains

When you sell an investment for a gain, the tax rate depends entirely on your holding period:

• Short-term capital gains — assets held one year or less — are taxed as ordinary income at your regular federal bracket, anywhere from 10% to 37%.
• Long-term capital gains — assets held more than one year — get preferential rates of 0%, 15%, or 20%, depending on your taxable income.

For 2026, the long-term capital gains brackets are:

Rate	Single filers	Married filing jointly
0%	Up to $49,450	Up to $98,900
15%	$49,450 – $306,850	$98,900 – $613,700
20%	Above $306,850	Above $613,700

This is a significant incentive to hold investments for longer than a year whenever it fits your broader financial plan — the tax difference between short-term and long-term treatment can be substantial.

Qualified vs Ordinary Dividends

Dividends aren't all taxed the same way either:

• Qualified dividends — paid by US corporations or qualifying foreign corporations, and held for a minimum required period — get the same preferential long-term capital gains rates (0%, 15%, or 20%) shown above.
• Ordinary (non-qualified) dividends — those that don't meet the qualified dividend requirements — are taxed as regular income at your ordinary federal bracket.

Most dividends from mainstream US stocks held in a normal brokerage account end up qualified, but it's worth checking your 1099-DIV each year, since it separates qualified from ordinary/non-qualified amounts.

Interest Income: Always Ordinary Income

Interest from bonds, savings accounts, CDs, and similar instruments is always taxed as ordinary income at your regular federal bracket — there's no preferential rate for interest the way there is for long-term gains and qualified dividends. This makes interest the least tax-efficient type of investment income, dollar for dollar, for most investors.

The Wash Sale Rule

A common mistake for investors trying to harvest tax losses: the wash sale rule disallows a tax loss on the sale of a security if you buy a "substantially identical" security within 30 days before or after the sale (a 61-day window total). If you trigger a wash sale, the loss is disallowed for that tax year and instead added to the cost basis of the replacement shares. This trips up investors who sell a losing position for the tax write-off, then immediately buy it back — the loss doesn't count.

Capital Losses Can Offset Gains and Some Ordinary Income

Capital losses first offset capital gains, gain-for-gain. If your losses exceed your gains for the year, you can use up to $3,000 of the net loss to offset ordinary income (like wages) per year. Any loss beyond that carries forward to future tax years, where it can offset future gains or continue chipping away at ordinary income at $3,000 per year.

Worked Example: Same Gain, Different Tax Bill

Investor A earns $50,000 in salary and has $5,000 in long-term capital gains. Their total taxable income keeps them under the $49,450 single-filer threshold for the 0% long-term rate, so that $5,000 gain is taxed at 0% — no federal tax on the gain at all.

Investor B earns $300,000 in salary and has the same $5,000 in long-term capital gains. Their income falls in the $49,450–$306,850 range, so the gain is taxed at the 15% long-term rate — about $750 in federal tax on the same $5,000 gain.

Same investment, same gain, very different tax outcome — purely because of where each investor's total income falls relative to the capital gains brackets.
