To pay less capital gains tax, hold assets longer than a year for lower long-term rates, use tax-advantaged accounts like IRAs, offset gains with capital losses, donate appreciated assets to charity, or sell your primary residence (if you meet ownership rules) to potentially exclude gains. Other tactics include tax-loss harvesting, timing sales to stay below 0% rate thresholds, and considering Qualified Small Business Stock (QSBS) or Opportunity Zones for real estate.
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 rates
A capital gains rate of 0% applies if your taxable income is less than or equal to: $48,350 for single and married filing separately; $96,700 for married filing jointly and qualifying surviving spouse; and. $64,750 for head of household.

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 "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 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).
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.
For 2025, the taxable income limit for the 0% bracket is $48,350 for single filers or $96,700 for married couples filing jointly. You calculate taxable income by subtracting the greater of the standard or itemized deductions from your adjusted gross 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.
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.
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.
You may be able to reduce your taxable income by maximizing contributions to retirement plans and health savings accounts. Tax-loss harvesting, asset location, and charitable giving are other tax strategies to consider to potentially lower your tax bill.
The "$1000 instant tax deduction" refers to a proposed Australian tax policy, specifically from the Albanese Labor government in 2025, allowing eligible workers to claim a flat $1,000 deduction for work-related expenses without needing receipts, simplifying tax returns for those with lower expenses but potentially costing those with higher expenses, starting from 1 July 2026. It's an option to replace itemised work-related deductions, not an extra refund, and doesn't affect non-work-related deductions like charity.
There are many options for transferring wealth to the next generation beyond cash gifts; 2503(c) trusts, trusts with Crummey withdrawal rights, UGMA/UTMA accounts, and 529 plans are some of the most common and tax-efficient strategies available.
Borrowing Against Assets Instead of Selling Them
Instead of selling stock and triggering capital gains taxes, billionaires like Bezos often borrow money against their assets. This allows them to access cash without paying taxes on stock sales. Think of it like this: Bezos owns billions in Amazon stock.
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%).
Under our scenario above, if the homeowner were single, her federal capital gain would be $400,000 - $250,000 = $150,000, and her federal capital gain tax would be $150,000 x 15% = $22,500.
