Almost everything you own and use for personal or investment purposes is a capital asset. Examples include a home, personal-use items like household furnishings, and stocks or bonds held as investments. When you sell a capital asset, the difference between the adjusted basis in the asset and the amount you realized from the sale is a capital gain or a capital loss. Generally, an asset's basis is its cost to the owner, but if you received the asset as a gift or inheritance, refer to Topic 703 for information about your basis. For information on calculating adjusted basis, refer to Publication 551, Basis of Assets. You have a capital gain if you sell the asset for more than your adjusted basis. You have a capital loss if you sell the asset for less than your adjusted basis. Losses from the sale of personal-use property, such as your home or car, aren't tax deductible.
Capital gains and losses are classified as long-term or short-term. If you hold the asset for more than one year before you dispose of it, your capital gain or loss is long-term. If you hold it one year or less, your capital gain or loss is short-term. To determine how long you held the asset, count from the day after the day you acquired the asset up to and including the day you disposed of the asset.
Report most sales and other capital transactions and calculate capital gain or loss on Form 8949 (PDF), Sales and Other Dispositions of Capital Assets, then summarize capital gains and deductible capital losses on Form 1040, Schedule D (PDF), Capital Gains and Losses. If you have a net capital gain, a lower tax rate may apply to the gain than the tax rate that applies to your ordinary income. The term "net capital gain" means the amount by which your net long-term capital gain for the year is more than your net short-term capital loss for the year. The term "net long-term capital gain" means long-term capital gains reduced by long-term capital losses including any unused long-term capital loss carried over from previous years. The tax rate on most net capital gain is no higher than 15% for most taxpayers. Some or all net capital gain may be taxed at 0% if you're in the 10% or 15% ordinary income tax brackets. However, a 20% tax rate on net capital gain applies to the extent that a taxpayer's taxable income exceeds the thresholds set for the 39.6% ordinary tax rate ($415,050 for single; $466,950 for married filing jointly or qualifying widow(er); $441,000 for head of household, and $233,475 for married filing separately).
There are a few other exceptions where capital gains may be taxed at rates greater than 15%:
- The taxable part of a gain from selling section 1202 qualified small business stock is taxed at a maximum 28% rate.
- Net capital gains from selling collectibles (such as coins or art) are taxed at a maximum 28% rate.
- The portion of any unrecaptured section 1250 gain from selling section 1250 real property is taxed at a maximum 25% rate.
Note: Net short-term capital gains are subject to taxation as ordinary income at graduated tax rates.
If you have a taxable capital gain, you may be required to make estimated tax payments. For additional information, refer to Publication 505, Tax Withholding and Estimated Tax, Estimated Taxes, and Do You Have to Pay Estimated Tax?
If your capital losses exceed your capital gains, the amount of the excess loss that you can claim on line 13 of Form 1040 to lower your income is the lesser of $3,000, ($1,500 if married filing separately) or your total net loss shown on line 16 of the Form 1040, Schedule D (PDF). If your net capital loss is more than this limit, you can carry the loss forward to later years. You may use the Capital Loss Carryover Worksheet found in Publication 550, Investment Income and Expenses, or in the Form 1040, Schedule D Instructions, to figure the amount you can carry forward.
Taxpayers with significant investment income may be subject to the Net Investment Income Tax (NIIT). For additional information on the NIIT, see Topic 559.
Additional information on capital gains and losses is available in Publication 550 and Publication 544, Sales and Other Dispositions of Assets. If you sell your main home, refer to Topics 701 and 703, and Publication 523, Selling Your Home.
