For a $100,000 capital gain, federal taxes depend on your holding period and income. Long-term gains (held >1 year) are typically taxed at 15% ($15,000) for most, or 0% for low-income earners. Short-term gains (held $\le$1 year) are taxed as ordinary income, likely 22%-24% ($22,000-$24,000+). Additional taxes may apply.
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%).
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.

A common way to defer or reduce your capital gains taxes is to use tax-advantaged accounts. Retirement accounts such as 401(k) plans, and individual retirement accounts offer tax-deferred investment. You don't pay income or capital gains taxes on assets while they remain in the account.
Capital gains tax on property depends on if it's your primary home (often excluded) or investment property, the holding period (short-term taxed as ordinary income, long-term at 0%, 15%, or 20%), and your income bracket; for primary homes, up to $250k (single) / $500k (married) profit is often excluded if lived in for 2 of last 5 years, while investment property gains are generally 0%, 15%, or 20% (long-term) or up to 37% (short-term), with potential 25% depreciation recapture.
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.
To calculate your capital gain or loss, you need to subtract the original cost of the asset and any associated expenses from the selling price. The remaining amount is your capital gain (if positive) or capital loss (if negative).
To calculate capital gain on property, find your Adjusted Basis (original cost + improvements - depreciation) and subtract it from the Net Selling Price (sale price - selling expenses like commissions) to get your Capital Gain; if it's your primary home, you might exclude up to $250k (single) or $500k (married) in gains if you meet residency requirements, notes IRS.gov, Jackson Hewitt and SmartAsset.com.
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.
You can avoid or defer capital gains tax on real estate by using the primary residence exclusion ($250k/$500k for 2-year ownership), executing a 1031 Exchange for investment properties, selling at a loss to offset gains, gifting to charity, holding the property in a self-directed IRA, or using strategies like installment sales, but the most common methods involve living in the home or reinvesting in another property.
Subtract your basis (what you paid) from the realized amount (how much you sold it for) to determine the difference. If you sold your assets for more than you paid, you have realized capital gains amount.
The "36-month rule" for capital gains tax (CGT) primarily refers to the UK's Principal Private Residence (PPR) Relief, where the final 36 months (or 9 months for most) of a property's ownership period are tax-exempt, even if not lived in, provided it was a main home at some point. In the US, the relevant rule for home sales is the "2-out-of-5-year rule" for the Section 121 exclusion, allowing up to $250k/$500k profit tax-free if owned and used as a main home for 2 of the 5 years before sale, with exceptions for unforeseen circumstances.
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%).
Can I avoid capital gains taxes?
Capital gains tax on $100,000 depends on if the gain is short-term (held a year or less, taxed as regular income at 10-37%) or long-term (held over a year, taxed at 0%, 15%, or 20% federally), plus potential state taxes and the Net Investment Income Tax (3.8%) for high earners. For long-term gains, a $100k profit could fall into the 15% bracket for many filers, meaning around $15,000 in federal tax, but your total income matters.
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.
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.
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.
