What Are Capital Gains?
A capital gain is the profit you earn when you sell an investment for more than you paid for it. Short-term gains (held under one year) are taxed at your ordinary income rate. Long-term gains (held over one year) receive preferential rates of 0%, 15%, or 20%.
How Capital Gains Work
Capital gains fall into two categories based on holding period. Short-term capital gains apply to assets held one year or less and are taxed at your ordinary income tax rate — potentially as high as 37%. Long-term capital gains apply to assets held for more than one year and receive preferential tax rates of 0%, 15%, or 20%, depending on your taxable income.
This distinction is one of the most important concepts in tax-efficient investing. Holding investments for at least one year before selling can significantly reduce your tax bill on profits. Capital gains taxes only apply when you sell and "realize" the gain. Unrealized gains (paper profits on investments you still hold) are not taxed.
Why Capital Gains Matter for Your Financial Goals
Understanding capital gains helps you make smarter decisions about when to sell investments. Many investors unknowingly create large tax bills by frequently buying and selling within short periods. A tax-aware approach — holding winners longer, harvesting losses to offset gains, and using tax-advantaged accounts — can meaningfully increase your after-tax returns over time.
Key Takeaway
The tax code rewards patience. Holding investments for over a year before selling can cut your tax rate on profits roughly in half.
