Capital gains tax rules depend on how long you hold an asset: short-term gains (held one year or less) are taxed as ordinary income (up to 37%), while long-term gains (held over a year) have preferential rates (0%, 15%, or 20% for 2025/2026, depending on income). Key factors include holding period, taxable income, filing status, asset type (collectibles taxed at 28%), and potential exclusions for primary homes.
You can make significant capital gains without paying tax on them, primarily through the $250,000/$500,000 exclusion for your main home sale (if you meet ownership/use tests) or by having low overall taxable income (reaching 0% capital gains brackets), which are up to around $48k (single) or $96k (joint) in taxable income for 2025. Other strategies include offsetting gains with losses, reinvesting in qualified opportunity zones, or holding assets long-term within tax-advantaged retirement accounts.
You can avoid or minimize capital gains tax by holding assets over a year for lower long-term rates, using tax-advantaged accounts (like Roth IRAs/401(k)s), donating appreciated assets to charity, using tax-loss harvesting to offset gains, or leveraging primary residence exclusions for your home, but completely avoiding tax often involves specific strategies like Qualified Opportunity Zones or 1031 exchanges for real estate.
To calculate capital gains tax, find the difference between your asset's sale price (minus selling costs) and its cost basis (purchase price plus fees) to get your gain or loss; then, determine if it's short-term (held ≤ 1 year, taxed as ordinary income) or long-term (held > 1 year, taxed at lower 0%, 15%, or 20% rates). Apply the correct rate to your gain to find the tax owed, using IRS tax brackets and forms like Schedule D.
On a $100,000 capital gain, you'll likely pay 15% for long-term gains, resulting in about $15,000 in federal tax (plus potential state tax), but it could be 0% or 20% depending on your total taxable income and filing status, while short-term gains are taxed as ordinary income (potentially 22-24%).
Second, capital gains taxes on accrued capital gains are forgiven if the asset holder dies—the so-called “Angel of Death” loophole. The basis of an asset left to an heir is “stepped up” to the asset's current value.
The primary "one-time" capital gains exemption in the U.S. allows single filers to exclude up to $250,000 (or $500,000 for married couples filing jointly) of profit from selling their main home, provided they've owned and lived in it for at least two of the last five years before the sale. While it's often called a one-time exclusion, you can use it multiple times, but you must wait two years before claiming it again on another property.
The capital gains tax over 65 is a tax that applies to taxable capital gains realized by individuals over the age of 65. The tax rate starts at 0% for long-term capital gains on assets held for more than one year and 15% for short-term capital gains on assets held for less than one year.
For example, a married couple filing jointly with $400,000 in taxable income would pay 32% tax on any short-term capital gains, based on 2025 tax rates. That same couple would pay 15% tax on any long-term capital gains.
As already mentioned, some assets are specifically exempt from CGT. Some of the most common examples are: private motor cars, including vintage cars. gifts to UK registered charities.
The "6-year rule" for Capital Gains Tax (CGT) in Australia allows you to treat a former main residence as tax-exempt for up to six years after you move out, even if you rent it out, enabling you to avoid CGT on any growth during that period. You qualify by moving out, choosing to treat it as your main home for tax, and can reset the rule by moving back in. If you rent it out for longer than six years, only the portion of the gain after the six-year mark becomes taxable.
The 2025 tax legislation signed into law by President Trump, commonly referred to as the One Big Beautiful Bill Act, largely preserves the existing capital gains tax framework. Long-term capital gains rates remain set at 0%, 15% and 20%, with no changes to the underlying brackets.
On the sale (or disposal) of something (an 'asset'), if it has increased in value to the extent that you make a profit, CGT may be due. In simple terms, CGT is a tax on the profit when you dispose of an asset that's increased in value.
If you sell your house and don't buy another, you'll have cash proceeds (after paying off the mortgage and selling costs) and need to decide on new housing, often renting or moving in with family; financially, you might benefit from the IRS capital gains exclusion (up to $250k/$500k profit if you've lived there two of the last five years), but you'll pay tax on gains beyond that, while also managing the new costs of renting or storage.

The simplest way to avoid capital gains tax is to regularly use your capital gains tax allowance (officially known as your annual exempt amount or AEA). How easy this is to do depends on the assets you are selling.
The amount of tax-free capital gain depends on the asset, but the most common exemption is for your primary home, allowing single filers to exclude up to $250,000 (or $500,000 for married couples) of profit if you've lived there 2 of the last 5 years. Additionally, certain long-term investments in qualified small businesses or Opportunity Funds, plus gains on inherited assets (due to stepped-up basis at death), can also be tax-free, while lower income levels may qualify for a 0% long-term capital gains tax rate.
