Income tax is levied on money you earn from working — wages, salaries, tips, and self-employment income. Federal rates are progressive, meaning higher portions of income are taxed at higher rates up to 37%.
Capital gains tax applies when you sell an asset for more than you paid. Short-term gains (held under 1 year) are taxed as ordinary income, while long-term gains enjoy preferential rates of 0%, 15%, or 20%.
