The simple formula for capital gains tax is to subtract the asset's cost basis (original purchase price plus fees) from the final sale price (minus selling costs) to find the total gain, then multiply that gain by your applicable tax rate.
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 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.
While capital gains may be taxed at a different rate, they're still included in your adjusted gross income (AGI) and can affect your tax bracket and your eligibility for some income-based investment opportunities.

Previously, individuals could exempt up to Rs. 1 lakh in gains from taxation, but this limit has been raised to Rs. 1.25 lakh. These changes aim to provide more benefits to middle and lower-income individuals by allowing them to keep more of their capital gains tax-free.
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.

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).

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.
