Capital gains and losses arise from the sale of assets such as stocks, bonds, real estate, or collectibles. When you sell an asset, the difference between the sale price and your purchase price—known as your “basis”—determines whether you have a capital gain or loss. If the sale price exceeds your basis, you have a capital gain; if it is less, you incur a capital loss. These outcomes directly affect your income tax obligations.
Understanding Short-Term vs. Long-Term Capital Gains and Losses
Capital gains and losses are categorized based on how long you’ve held the asset:
- Short-term: Assets held for one year or less. Gains are taxed at your ordinary income tax rates, which can be higher.
- Long-term: Assets held for longer than one year. Gains benefit from preferential, lower tax rates designed to encourage long-term investment.
This distinction is key because long-term capital gains rates, which can be 0%, 15%, or 20% depending on your income, are generally lower than ordinary income tax rates.
Tax Treatment and Reporting
When you realize capital gains, you must report them on your tax return using IRS Schedule D (Form 1040), which summarizes your gains and losses for the year. Capital losses can offset capital gains dollar for dollar, reducing your taxable gains. If your losses exceed your gains, you can deduct up to $3,000 ($1,500 if married filing separately) of the excess loss against other income annually, with remaining losses carried forward to future years.
Examples
-
Stock Sale Profit: You purchase 100 shares of a company at $20 each and sell them a year later at $30 each. Your capital gain is $1,000 ($3,000 sale proceeds minus $2,000 purchase cost).
-
Real Estate Gain: Selling a home bought for $200,000 at $250,000 results in a $50,000 gain. A primary residence exclusion may apply, allowing you to exclude up to $250,000 ($500,000 if married filing jointly) from taxable gains per IRS guidelines IRS Topic 701.
-
Investment Loss: Purchasing shares at $5,000 and selling them for $3,000 results in a $2,000 capital loss, which can be used to offset other gains or deducted against income as allowed.
