Passive income is earnings derived from a rental property, limited partnership or other enterprise in which a person is not actively involved. As with active income, passive income is usually taxable. However, it is often treated differently by the Internal Revenue Service (IRS). Portfolio income is considered passive income by some analysts, so dividends and interest would therefore be considered passive.
There are many people who get paid vast amounts of money to become the CEO of a company, play professional sports, or star in a movie. Earning a high active income is often a lot of hard work and requires a dedication beyond most of us. It’s also limited because no matter how much money you get paid you still need to show up to work to earn your money.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
