Yes, capital gains are considered taxable income by the IRS and are added to your other earnings (wages, interest, etc.) to calculate your total income, but they are taxed at different rates depending on how long you held the asset: short-term gains (held one year or less) are taxed as regular income, while long-term gains (held over a year) get preferential rates (0%, 15%, or 20%).
Profits from capital gains are a type of income and are considered taxable. Some capital gains and qualified dividends are taxed at a separate (and lower) rate compared to the income tax rate. In total, there are seven federal income tax brackets for the 2026 tax year.
You must hold the possession of these assets for a predetermined period, typically at least one year, to be allowed to make a sale. Once you sell any of these long-term assets, you earn long-term capital gains, which add to your taxable income.
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.
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.
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.
Capital gains tax assessment and exemptions
Capital gains tax is payable as part of your income tax assessment for the relevant income year. It's not a separate tax, instead, it forms part of your assessable income.
Yes, capital gains are included in MAGI. Capital gains are the profits you earn from selling assets like stocks, bonds, real estate, and other investments. These gains contribute to your overall income and can significantly impact your MAGI, which in turn, affects your eligibility for various tax benefits.
How to calculate your AGI. Start with your total (gross) income from all sources. This includes wages, tips, interest, dividends, capital gains, business income, retirement income and other forms of taxable income.
Capital gains tax on $100k depends on how long you held the asset: short-term gains (held 1 year or less) are taxed as ordinary income (10-37%), while long-term gains (held over a year) are taxed at lower rates (0%, 15%, or 20%) based on your total taxable income and filing status, with 15% often applying in this range, plus potentially a 3.8% Net Investment Income Tax (NIIT) if your income is high.
The 20% rule for capital gains refers to the highest federal tax rate for long-term capital gains, applying to higher income brackets when you sell investments (stocks, real estate) held for over a year, with lower rates of 0% and 15% for lower incomes, and even higher rates for special assets like collectibles. This rate kicks in for single filers earning over approximately $492,300 (2024) or $533,401 (2025), and higher for joint filers, making holding assets over a year a key tax strategy.
Capital gains tax on $300,000 depends on your filing status and total income, but for most, it will be taxed at the 15% federal rate, meaning around $45,000 in tax, potentially rising to 20% if your total income is very high, and you'll also need to account for state taxes and potentially a 3.8% Medicare surtax. A $300,000 gain usually falls into the 15% bracket for single filers (above $48,350) and married filing jointly (above $96,700), while for married filing separately, it hits the 20% bracket (over $300,000).
Capital gains, especially long-term ones, are usually taxed at lower rates compared to ordinary income. That means if you hold your investments like mutual funds or stocks for more than a year, you might pay less tax on the gains than you would on your salary or interest income.
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 "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.
Capital gains tax rates

When you sell your primary residence, $250,000 of capital gains (or $500,000 for a couple) are exempted from capital gains taxation. This is generally true only if you have owned and used your home as your main residence for at least two out of the five years prior to the sale.
