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%).
Section 121 of the Internal Revenue Code (IRC), part of the Taxpayer Relief Act of 1997, allows homeowners to exclude up to $250,000 of capital gains ($500,000 for married couples filing jointly) when selling their primary residence.

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.
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.

If you rent it out for longer than six years, only the portion of the gain after the six-year mark becomes taxable.
The 2025 tax legislation signed into law by President Trump, commonly referred to as the One Big Beautiful Bill Act, largely preserves the existing capital gains tax framework. Long-term capital gains rates remain set at 0%, 15% and 20%, with no changes to the underlying brackets.

Most home improvements aren't immediately tax deductible as personal expenses, but capital improvements (adding value, prolonging life, new use) increase your home's cost basis, reducing taxes when you sell; specific energy-efficient upgrades and medically necessary changes can offer tax credits or deductions now, and home office or rental property improvements have separate rules.
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.

Also, the Income Tax Act does state that capital gains arise when an individual transfers a capital asset. However, Section 47 of the Act states that this provision excludes 'gifts' from the definition of 'transfer'. Thus, even as per the Income Tax Act, the sender of a gift can enjoy tax exemptions.
