Capital gains refer to the profit earned from the sale of an asset that has increased in value since it was purchased. Assets subject to capital gains taxation include stocks, bonds, real estate (excluding some exemptions), collectibles, and cryptocurrencies. When the sale price exceeds the original purchase price, the difference is the capital gain, which may be taxable depending on various factors.
Understanding Capital Gains Taxation in 2025
The IRS categorizes capital gains into two types based on the duration the asset was held before sale:
- Short-term capital gains: Gains from assets held for one year or less. These are taxed at the seller’s ordinary income tax rates, which in 2025 range from 10% to 37% based on income brackets.
- Long-term capital gains: Gains from assets held for more than one year. These enjoy preferential tax rates of 0%, 15%, or 20%, depending on your taxable income. Certain high-income taxpayers may also face an additional 3.8% Net Investment Income Tax (NIIT) on top of capital gains tax.
These differential rates are designed to encourage longer-term investments by reducing the tax burden on long-term gains.
Examples of Capital Gains
- Selling shares of stock at a higher price than their purchase price.
- Profiting from the sale of rental or investment property (subject to depreciation recapture rules).
- Selling a primary residence can qualify for an exclusion of gain up to $250,000 for single filers or $500,000 for married couples if specific ownership and use criteria are met (see Capital Gains Exclusion on Home Sale).
- Selling collectibles or valuable physical assets like art or antiques.
- Disposing of cryptocurrencies at a profit.
Reporting Capital Gains
All realized capital gains must be reported to the IRS on your federal income tax return. Typically, you will use Form 8949 – Sales and Other Dispositions of Capital Assets to detail each transaction, and then summarize the totals on Schedule D (Form 1040).
Strategies to Manage Capital Gains Taxes
- Hold assets for more than one year: Benefit from lower long-term capital gains tax rates.
- Tax-loss harvesting: Offset capital gains by realizing capital losses in the same tax year.
- Use tax-advantaged accounts: Utilize retirement accounts like IRAs and 401(k)s where capital gains are deferred or not taxed.
- Leverage exclusions when selling your primary residence: As noted above, taxpayers often qualify for significant exclusions under IRS rules.
Common Misunderstandings
- Capital gains tax is not assessed until the sale of the asset is completed; simply holding an asset does not trigger tax.
- Not all gains are taxed at the same rate; the holding period and income levels are key factors.
- Capital gains tax can be minimized or deferred through legitimate tax planning strategies.
