The retail industry, excluding wholesale, contributed $482 billion (22% of GDP) and employed 249.94 million people (57% of the workforce) in 2016. The industry is the second largest employer in India, after agriculture.[153] The Indian retail market is estimated to be US$600 billion and one of the top-five retail markets in the world by economic value. India has one of the fastest-growing retail markets in the world,[243][244] and is projected to reach $1.3 trillion by 2020.[245][246]
If we invest this financial capital well enough and do not lose it or spend it all along the way, it may even grow at a compound rate that matches or exceeds inflation and taxes. Most of us reinvest inflows from financial capital during the accumulation years. Our investment vehicles tend to be geared for total return and capital gains instead of monthly income generation.
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. 

3) Create A Plan. Mark Spitz once said, “If you fail to prepare, you’re prepared to fail.” You must create a system where you are saving X amount of money every month, investing Y amount every month, and working on Z project until completion. Things will be slow going at first, but once you save a little bit of money you will start to build momentum. Eventually you will find synergies between your work, your hobbies, and your skills which will translate into viable income streams.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!

​Network marketing, or multi-level marketing, seems to be on the rise. Companies such as Young Living Oils, Avon, Pampered Chef, and AdvoCare are all multi-level marketing companies. You can earn passive income through network marketing by building a team underneath you (often referred to as a down line.) Once you have a large team you can earn commissions off of their sales without having to do much.
As the third-largest economy in the world in PPP terms, India has attracted foreign direct investment (FDI).[301] During the year 2011, FDI inflow into India stood at $36.5 billion, 51.1% higher than the 2010 figure of $24.15 billion. India has strengths in telecommunication, information technology and other significant areas such as auto components, chemicals, apparels, pharmaceuticals, and jewellery. Despite a surge in foreign investments, rigid FDI policies[302] were a significant hindrance. Over time, India has adopted a number of FDI reforms.[301] India has a large pool of skilled managerial and technical expertise. The size of the middle-class population stands at 300 million and represents a growing consumer market.[303]

OK, I know what you're thinking — maybe you're not a writer. However, as Tamez says above, chances are, you're an expert sy ~something~. Also, chances are that other people want to know what you know. So whether you write an eBook on dating or tips on how to fix your car, once you write, self-publish the book, and let it go, it can sit on a site like Amazon and sell itself. Of course, you can market it, too, but that's another story! Some sites let you keep most of the earnings, while others do not.
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
