What Are Capital Gains and Losses?
Capital gains and losses are the profit or loss from selling a capital asset. A capital gain occurs when the sale price is higher than the asset's tax basis. A capital loss occurs when the sale price is lower than the asset's tax basis.
Capital assets can include stocks, bonds, mutual funds, ETFs, real estate, collectibles, and other property held for investment or personal use. For tax purposes, the holding period, asset type, basis, and whether the gain is realized all matter.
Key Takeaways
- A capital gain is profit from selling a capital asset for more than its basis.
- A capital loss is a sale for less than basis, but not every personal loss is deductible.
- Short-term gains and long-term gains can be taxed differently.
- Capital losses can offset capital gains, subject to tax rules and limits.
How the Tax Treatment Differs
Category | Basic Meaning | Financial Effect |
|---|---|---|
Unrealized gain | The asset has increased in value but has not been sold | Usually no taxable gain has been triggered yet |
Realized gain | The asset was sold or otherwise disposed of for more than basis | May need to be reported on a tax return |
Short-term gain | Gain on an asset generally held one year or less | Often taxed at ordinary income tax rates |
Long-term gain | Gain on an asset generally held more than one year | May qualify for lower capital gains tax rates |
Capital loss | Sale for less than basis | May offset gains, though personal-use losses are generally not deductible |
How Basis Shapes the Result
Tax basis is usually what the owner paid for the asset, adjusted for certain events. Brokerage investments may be adjusted for reinvested dividends, return of capital, stock splits, or wash sale rules. Real estate basis may be adjusted for improvements, depreciation, and selling costs.
The gain or loss is not measured against the highest price the asset ever reached. It is measured against basis and the sale proceeds. That is why accurate records matter, especially for assets acquired through gifts, inheritance, employee compensation, or multiple purchases over time.
Where It Shows Up
Capital gains and losses commonly appear when investors sell securities, rebalance taxable portfolios, sell a second home or rental property, dispose of business interests, or liquidate inherited assets. Tax forms may include broker statements, Form 1099-B, Form 8949, and Schedule D.
The tax result can affect cash flow after a sale. A gain may create a tax bill, while a loss may reduce taxable gains or, within limits, offset some other income. Timing can matter, but tax decisions should be weighed against investment risk, concentration, liquidity needs, and transaction costs.
The Bottom Line
Capital gains and losses measure the tax result of selling capital assets. The practical impact depends on basis, holding period, asset type, and whether the gain or loss is realized. The concept matters because investment returns are not just about price movement; after-tax proceeds are what the owner actually keeps.
