What Are Capital Gains?
A capital gain occurs when you sell an asset for more than you paid for it. In the US, capital gains are taxed at different rates depending on how long you held the asset. Short-term capital gains (held under one year) are taxed at your ordinary income tax rate, while long-term capital gains (held over one year) receive preferential rates of 0%, 15%, or 20%.
Capital gains tax applies to stocks, bonds, real estate, cryptocurrency, collectibles, and most other investment assets. Understanding your potential tax liability is essential for making informed sell decisions and planning your investment strategy.
The difference between short-term and long-term rates can be dramatic. A taxpayer in the 32% bracket pays 32% on short-term gains but only 15% on long-term gains, saving 17 cents per dollar. On a $25,000 gain, that is $4,250 in savings just for holding one year.
