In 2025, you do not pay federal taxes on long-term capital gains if your total taxable income is $48,350 or less for single filers ($96,700 for married filing jointly). For 2026, these 0% rate thresholds increase to $49,450 for single filers and $98,900 for married couples.
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 do this if you meet all three conditions: You owned the home for a total of at least two years. You used the home as your primary residence for a total of at least two years in the last five-years before the sale. You haven't excluded the gain from another home sale in the two-year period before the sale.
Capital Gains Tax allowances
You only have to pay Capital Gains Tax on your overall gains above your tax-free allowance (called the Annual Exempt Amount). The Capital Gains tax-free allowance is: £3,000.
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%).

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.
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.
Long-term capital gains tax applies to assets held for more than a year. The long-term capital gains tax rates are 0%, 15% and 20%, depending on your income. For many taxpayers, these rates are much lower than the ordinary income tax rate.

One of the simplest yet most expensive mistakes is misunderstanding the difference between short-term and long-term capital gains taxes. Short-term gains — profits from assets held less than a year — are subject to typical income tax rates, which can reach 37% for high earners.
Unlike business expenses, you can't simply write off a kitchen renovation or new flooring on your current tax return. However, this doesn't mean your improvements provide no tax benefit. They may impact your capital gains tax when selling the home.
Manage your tax bracket
At the lowest income levels, the capital gains tax rate is 0%, which means no federal income taxes on your gains (state income taxes may still apply). For a married couple filing jointly, the maximum taxable income to qualify for the 0% rate is $96,700 in 2025.
The "2-year, 5-year rule" primarily refers to the IRS rule allowing homeowners to exclude up to $250,000 (or $500,000 married) of capital gains from the sale of their primary residence if they owned and lived in it as their main home for at least 2 years out of the 5 years before the sale, meeting both ownership and use tests within that 5-year window. There's also a "5-year rule" for Roth IRAs, requiring separate 5-year periods for contributions and conversions to avoid taxes.

To qualify for 0% capital gains tax, you must have long-term capital gains (assets held over a year) and your taxable income (after deductions) must fall below specific IRS thresholds, which change annually but are roughly <$48,350 for single filers and <$96,700 for married filing jointly for the 2025 tax year, allowing for higher total income when combined with deductions like the standard deduction. The key is keeping your adjusted gross income (AGI) low enough so that after subtracting deductions, your taxable income remains within these limits.
Lifetime capital gains exemption eligibility
Qualifying for the exclusion
You're eligible for the exclusion if you have owned and used your home as your main home for a period aggregating at least two years out of the five years prior to its date of sale. You can meet the ownership and use tests during different 2-year periods.
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 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.
Billionaires often employ the “buy, borrow, die” strategy to avoid income and capital gains taxes. First, they acquire appreciating assets like stocks or real estate. Instead of selling these assets when they need cash (which would trigger capital gains tax), they borrow against them at favorable interest rates.
