Passive income differs from active income which is defined as any earned income including all the taxable income and wages the earner get from working. Linear active income refers to one constantly needed to stay active to maintain the stream of income, and once an individual chooses to stop working the income will also stop, examples of active income include wages, self-employment income, material participation in an s corp, or a partnership.[4] portfolio income is derived from investments and includes capital gains, interest, dividends, and royalties.[5]

If an investor puts $500,000 into a candy store with the agreement that the owners would pay the investor a percentage of earnings, that would be considered passive income as long as the investor does not participate in the operation of the business in any meaningful way other than placing the investment. The IRS states, however, that if the investor did help manage the company with the owners, the investor's income could be seen as active since the investor provided "material participation." 

An investment property is an asset purchased with the sole purpose of earning revenue. Income from an investment property can be earned through leasing space within an asset or an eventual sale of the asset. Examples of this include a commercial rental property where business lease office space or an apartment building where tenants rent a home to live in.
