If you put $500,000 into a candy store with the agreement that the owners would pay you a percentage of earnings, that would be considered passive income as long as you do not participate in the operation of the business in any meaningful way other than placing the investment. The IRS states, however, that if you did help manage the company with the owners, your income could be seen as active, because you provided “material participation."
Decide to invest in dividend stocks. Dividend stocks pay out a portion of the company's profits to shareholders. These dividends are paid at regular intervals, so they produce a regular income stream. Investors who hold a large amount of this type of stock are known as "income investors" because they prioritize regular dividends over stock value growth.[1]
