Author Bio: Sam started Financial Samurai in 2009 to help people achieve financial freedom sooner, rather than later. He spent 13 years working in investment banking, earned his MBA from UC Berkeley, and retired at age 34 in San Francisco. Everything Sam writes is based on first-hand experience because money is too important to be left up to pontification.

The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
