Frequently Asked Questions

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

Short-term gains apply to assets held for less than a year and are taxed at ordinary income rates (10-37%). Long-term gains apply to assets held for more than a year and are taxed at lower rates (0%, 15%, or 20%).

What is the Net Investment Income Tax (NIIT)?+

NIIT is an additional 3.8% tax on investment income for high earners (over $200,000 single, $250,000 married filing jointly). It is added on top of regular capital gains tax.

How do capital gains interact with my other income?+

Capital gains stack on top of your ordinary income. If your total income pushes you into a higher bracket, your gains may face a higher rate. Long-term gains have their own brackets, which may differ from ordinary income.

Can I offset gains with capital losses?+

Yes. Capital losses first offset gains of the same type (short-term against short-term, long-term against long-term). Net losses can offset up to $3,000 of ordinary income. Excess losses carry forward to future years.
