A capital gain is realized when a capital asset is sold or exchanged at a price higher than its basis. Basis is an asset’s purchase price, plus commissions and the cost of improvements less depreciation. A capital loss occurs when an asset is sold for less than its basis. Gains and losses (like other forms of capital income and expense) are not adjusted for inflation.
Capital gains and losses are classified as long term if the asset was held for more than one year, and short term if held for a year or less. Short-term capital gains are taxed as ordinary income at rates up to 37 percent; long-term gains are taxed at lower rates, up to 20 percent. Taxpayers with modified adjusted gross income above certain amounts are subject to an additional 3.8 percent net investment income tax (NIIT) on long- and short-term capital gains.
The Tax Cuts and Jobs Act (TCJA), enacted at the end of 2017, retained the preferential tax rates on long-term capital gains and the 3.8 percent NIIT. TCJA separated the tax rate thresholds for capital gains from the tax brackets for ordinary income for taxpayers with higher incomes (table 1). The thresholds for the new capital gains tax brackets are indexed for inflation, but, as under prior law, the income thresholds for the NIIT are not. TCJA also eliminated the phaseout of itemized deductions, which had raised the maximum capital gains tax rate above the 23.8 percent statutory rate in some cases.
There are special rules for certain types of capital gains. Gains on art and collectibles are taxed at ordinary income tax rates up to a maximum rate of 28 percent. Up to $250,000 ($500,000 for married couples) of capital gains from the sale of principal residences is tax-free if taxpayers meet certain conditions, including having lived in the house for at least 2 of the previous 5 years. Up to the greater of $10 million of capital gains or 10 times the basis on stock held for more than five years in a qualified domestic C corporation with gross assets under $50 million on the date of the stock’s issuance are excluded from taxation. Also excluded from taxation are capital gains from investments held for at least 10 years in designated Opportunity Funds. Gains on Opportunity Fund investments held between 5 and 10 years are eligible for a partial exclusion.
Capital losses may be used to offset capital gains plus up to $3,000 of other taxable income. The unused portion of a capital loss may be carried over to future years.
The tax basis for an asset received as a gift equals the donor’s basis. However, the basis of an inherited asset is “stepped up” to the value of the asset on the date of the donor’s death. The step-up provision effectively exempts from income tax any gains on assets held until death.
C corporations pay the regular corporation tax rates on the full amount of their capital gains and may use capital losses only to offset capital gains, not other kinds of income.
Maximum Tax Rate on Capital Gains
For most of the history of the income tax, long-term capital gains have been taxed at lower rates than ordinary income (figure 1). The maximum long-term capital gains and ordinary income tax rates were equal in 1988 through 1990. Since 2003, qualified dividends have also been taxed at the lower rates applied to long-term capital gains.
