When you sell an investment you've held for a while, the profit you make is taxed differently than money you earn from work. Long-term capital gains are the profits from selling assets—stocks, real estate, mutual funds—that you've owned for more than a year. How these gains are taxed, and what information you need to track them, matters significantly for your finances and tax bill.
A capital gain is simply the difference between what you paid for an asset and what you sold it for. If you bought 100 shares of stock for $1,000 and sold them for $1,500, your gain is $500.
The "long-term" label applies when you've held that asset for more than one year before selling. This distinction is important: the IRS taxes long-term gains at preferential rates compared to short-term gains (assets held one year or less), which are taxed as ordinary income.
The federal tax rate on long-term capital gains depends on your ordinary income tax bracket and filing status, not directly on the size of your gain. The rates are typically lower than the rates on ordinary income—currently in the range of 0%, 15%, or 20% for most taxpayers, though this can change with tax law.
This is one reason long-term holding periods matter: the tax advantage can be substantial. But the exact rate you'll pay depends on factors like:
To report long-term gains correctly and potentially reduce your tax burden, keep clear records for every investment you sell:
| Information | Why It Matters |
|---|---|
| Purchase date | Determines if the gain qualifies as long-term |
| Cost basis (what you paid) | Calculates your actual gain or loss |
| Sale date and price | Required for tax reporting; confirms holding period |
| Dividends or distributions reinvested | These may adjust your cost basis upward |
| Sales commissions or fees | Can reduce your taxable gain |
| Type of asset | Some assets have special rules (real estate, collectibles) |
Many custodians (brokerage firms, retirement plan administrators) provide this information on year-end statements or through online accounts, but you are responsible for accuracy. If you inherited investments or received gifts, you may have a stepped-up basis (a reset to the asset's value on the date of inheritance or gift), which affects what your actual gain is.
For people over 65, long-term gains become relevant in several common situations:
No two situations are identical. Your long-term gains tax liability depends on:
To be prepared:
Long-term capital gains rules exist, and they often favor patient investors and strategic selling. Understanding the framework helps you make informed decisions about when and what to sell—but the right move always depends on your individual circumstances, goals, and complete financial picture.
