Investing in a business: Another good way to generate passive income is to invest in a business --even a small one -- in return for a percentage of the profits - just like Shark Tank, only smaller. Lending $10,000 to a local business that, for example, is working on a mobile app for Apple phones could lead to a passive income-generated share of the profits when that mobile app starts selling like hot cakes.
According to Uncle Sam, you need to be "materially involved" in an enterprise to earn active income. With passive income, it's just the opposite, as the IRS deems you to be earning passive income if you're not materially involved with a profit-making enterprise. By and large, expect income to be taxable if you are engaged in a passive income enterprise. You will need to report earnings to the IRS.
In many instances, a business project consumes far more resources than meets the eye. Assume you are running a dog grooming business from the first floor of your two-family house and that your daughter is helping you over the weekends. The business is making $50,000 per year and you want to know whether this represents a positive or negative residual value. In this case, you must deduct from $50,000 all opportunity costs which include the money you would make if you rented the first floor of your house to a business; how much you plus your daughter would earn if you invested the same amount of time and effort into a regular job; and how much the total assets owned by the business would return every year if they were sold off and the cash proceeds were held in a bank account.
4. eCourses: A step up from an eBook is an eCourse. These are a more thorough training that you can offer in a text format and typically include supplemental formats like video, worksheets, audio and more. This opportunity involves more work and likely an investment into a platform for delivery like Teachable, but you can also ask a lot more money. If you have been around the blogging world for any period of time you know it’s not unusual to see eCourses being sold for several hundred dollars if not more.

Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
