Capital Gains Tax: How It Works, Rates and Calculator

The IRS refers to most items someone owns as "capital assets.^[0]

The difference between your capital gains and your capital losses is called your “net capital gain.” For example, if you sold a stock for a $10,000 profit this year and sold another at a $4,000 loss, your net capital gain is $6,000.

Capital gains taxes are taxes on the profit from the sale of your asset. Similar to income taxes, capital gains taxes are progressive, but how the money is taxed also depends on what you sold, how long you owned it before selling, your taxable income and your filing status. Holding onto an asset for more than a year before selling generally results in a more favorable tax treatment.

Capital gains can be subject to either short-term tax rates or long-term tax rates. Short-term capital gains are taxed according to ordinary income tax brackets, which range from 10% to 37%. Long-term capital gains are taxed at 0%, 15%, or 20%.

Some exceptions:

• High-earning individuals may also need to account for the net investment income tax (NIIT), an additional 3.8% tax that can be triggered if your income exceeds a certain limit.

• Long-term capital gains on so-called “collectible assets” can be taxed at a maximum of 28%. This includes items such as coins, precious metals, antiques and fine art. Short-term gains on such assets are taxed at the ordinary income tax rate^[0]

1. Hold on

Whenever possible, hold an asset for longer than a year so you can qualify for the long-term capital gains tax rate, because it's significantly lower than the short-term capital gains rate for most assets. Our capital gains tax calculator shows how much that could save.

2. Use tax-advantaged accounts

These include 401(k) plans, individual retirement accounts and 529 college savings accounts, in which the investments grow tax-free or tax-deferred. That means you don’t have to pay capital gains tax if you sell investments within these accounts. Roth IRAs and 529 accounts in particular have big tax advantages. Qualified distributions from those are tax-free; in other words, you don’t pay any taxes on investment earnings. With traditional IRAs and 401(k)s, you’ll pay taxes when you take distributions from the accounts in retirement.

3. Rebalance with dividends

Rather than reinvest dividends in the investment that paid them, rebalance by putting that money into your underperforming investments. Typically, you'd rebalance by selling securities that are doing well and putting that money into those that are underperforming. But using dividends to invest in underperforming assets will allow you to avoid selling strong performers — and thus avoid capital gains that would come from that sale.

4. Use the home sales exclusion

If you sold a house the previous year, you may be able to exclude a portion of the gains from that sale on your taxes. To qualify, you must have owned your home and used it as your main residence for at least two years in the five-year period before you sell it. You also must not have excluded another home from capital gains in the two-year period before the home sale. If you meet those rules, you can exclude up to $250,000 in gains from a home sale if you’re single, and up to $500,000 if you’re married filing jointly.

5. Look into tax-loss harvesting

The IRS taxes your net capital gain, which is simply your total long- or short-term capital gains (investments sold for a profit) minus the corresponding long- or short-term total capital losses (investments sold at a loss). The strategic practice of selling off specific assets at a loss to offset gains is called tax-loss harvesting. This strategy has many rules and isn't right for everyone, but it can help to reduce your taxes by lowering the amount of your taxable gains.

If your net capital loss exceeds your net capital gains, you can also offset your ordinary income by up to $3,000 ($1,500 for those married filing separately). Any additional losses can be carried forward to future years to offset capital gains or up to $3,000 of ordinary income per year.
