Frequently Asked Questions

What is the difference between short-term and long-term capital gains?

Short-term gains (assets held less than 1 year) are taxed at your ordinary income rate (10-37%). Long-term gains (held 1+ years) get preferential rates: 0%, 15%, or 20% depending on income. Holding investments longer saves significant tax.

What are the long-term capital gains rates?

For 2024 single filers: 0% on gains up to $47,025 taxable income, 15% on gains from $47,026-$518,900, and 20% on gains above $518,900. High earners may also owe the 3.8% Net Investment Income Tax.

Can I offset capital gains with losses?

Yes. Capital losses offset capital gains dollar for dollar. If you have excess losses, you can deduct up to $3,000 per year against ordinary income and carry forward remaining losses to future years. This is called tax-loss harvesting.
