What Is Capital Gains Tax and What Are the 2025 Rates?
If you sold stocks, crypto, real estate, or another investment for a profit, you may owe capital gains tax. Understanding how it works — especially the capital gains tax rates 2025 — is essential for smart financial planning and avoiding surprises at tax time.
In the United States, capital gains tax applies to the profit you earn when you sell a capital asset for more than you paid for it. The amount you owe depends on how long you held the asset and your total taxable income.
This guide breaks down everything you need to know about capital gains tax, including updated capital gains tax rates 2025, short-term vs. long-term rules, and which assets are taxable.
What Is Capital Gains Tax?
Capital gains tax is the tax imposed on the profit from selling an asset. The key word here is profit. If you bought an asset for $10,000 and sold it for $15,000, the $5,000 difference is considered a capital gain.
Unrealized gains — meaning assets that have increased in value but haven’t been sold — are not taxable. You only owe capital gains tax once you actually sell the asset.
While the concept sounds simple, the U.S. tax code adds complexity through different holding periods, income thresholds, and exemptions that can significantly affect how much you pay.
Short-Term vs. Long-Term Capital Gains
One of the most important factors in determining your tax bill is how long you owned the asset before selling it.
Short-Term Capital Gains
Short-term capital gains apply when you sell an asset that you held for one year or less. These gains are taxed as ordinary income, meaning they follow the same federal tax brackets as your salary or business income.
If you fall into a higher income tax bracket, your short-term gains could be taxed at rates as high as 37%. This is why short-term investing often leads to a higher tax burden.
Long-Term Capital Gains
Long-term capital gains apply to assets held for more than one year. These gains benefit from lower tax rates, which is why long-term investing is often more tax-efficient.
For U.S. taxpayers, the capital gains tax rates 2025 for long-term gains remain capped at 0%, 15%, or 20%, depending on your taxable income and filing status.
What Assets Are Subject to Capital Gains Tax?
Capital gains tax is not limited to stocks. In the U.S., most assets that can increase in value are considered capital assets.
Capital gains tax commonly applies to profits from selling real estate, stocks, bonds, mutual funds, cryptocurrency, NFTs, jewelry, rare coins, and other collectibles.
While ETFs are generally tax-efficient, gains realized from selling them may still be taxable depending on how and when they’re sold.
