However, under certain circumstances, payment for personal services performed in the United States is not considered income from sources within the United States. For example, personal services performed by an independent nonresident alien contractor specifically exempted by a tax treaty. For more examples, see the Pay for Personal Service section in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities.
Good ranking FS, I’d have to agree with the rankings. And it looks like your portfolio covers five of the six! Some people consider real estate passive will others classify it as active. But every scenario is different, whether you are doing all the maintenance and managing yourself, or you are contracting out a lot of the work. Obviously it takes a lot more time and effort than purchasing a 36 month CD and “setting it and forgetting it.”

The 1872 census revealed that 91.3% of the population of the region constituting present-day India resided in villages.[111] This was a decline from the earlier Mughal era, when 85% of the population resided in villages and 15% in urban centers under Akbar's reign in 1600.[112] Urbanisation generally remained sluggish in British India until the 1920s, due to the lack of industrialisation and absence of adequate transportation. Subsequently, the policy of discriminating protection (where certain important industries were given financial protection by the state), coupled with the Second World War, saw the development and dispersal of industries, encouraging rural–urban migration, and in particular the large port cities of Bombay, Calcutta and Madras grew rapidly. Despite this, only one-sixth of India's population lived in cities by 1951.[113]
To these human costs can be added the massive economic waste associated with the water and sanitation deficit.… The costs associated with health spending, productivity losses and labour diversions … are greatest in some of the poorest countries. Sub-Saharan Africa loses about 5% of GDP, or some $28.4 billion annually, a figure that exceeds total aid flows and debt relief to the region in 2003.Source 10

The goal of creating multiple income streams should be to maximize your potential in each category available to you.  If you are just starting out, it really isn’t reasonable to expect you to generate tons of rental income.  However, if you start maximizing your income generating potential through your primary salary, you will find yourself having excess income that you can reinvest to generate additional income streams and earn more money.
The five-year plans, especially in the pre-liberalisation era, attempted to reduce regional disparities by encouraging industrial development in the interior regions and distributing industries across states. The results have been discouraging as these measures increased inefficiency and hampered effective industrial growth.[397] The more advanced states have been better placed to benefit from liberalisation, with well-developed infrastructure and an educated and skilled workforce, which attract the manufacturing and service sectors. Governments of less-advanced states have tried to reduce disparities by offering tax holidays and cheap land, and focused on sectors like tourism which can develop faster than other sectors.[398][399] India's income Gini coefficient is 33.9, according to the United Nations Development Program (UNDP), indicating overall income distribution to be more uniform than East Asia, Latin America and Africa.[10]
What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 
If you want to top up your income without taking on a strenuous second job, your first port of call should be your very own skillset. If you have a natural talent that could help others, you have an instant “in” to easy money. Whether you’re a gifted guitarist, mathematical genius or speak a second language, almost any talent can be turned into cash. Offering one-to-one coaching is a flexible way to make a solid hourly rate, and enables you to take on as much or as little work as you wish. Find local clients by placing adverts in the library, schools and community bulletin boards and share your talent in exchange for a fee.

However, when you lack the money, you need time. You'll need to invest the upfront time now in order to reap the benefits of automatic income later. It just doesn't happen overnight. So don't expect it to. However, you can do this without quitting your day job. All it takes is some sincere effort over a consistent period, and voila! But, to get there, you'll need to consistently burn the midnight oil or get up at the crack of dawn. Your choice.
This is an interesting take and good advice for those who probably do not need to ever worry about becoming destitute. I’m sorry but too many of your options including your own list of income require quite a bit of initial investment/capital and these suggestions are useless to those living paycheck to paycheck. I’d like to see the average low to middle income household purchase additional property for rental, invest in their portfolio (if they can even start one), or even afford to have a vehicle or room to rent. Far too first world of a solution for the general public.
“The biggest surprise is real estate being second to last on my Passive Income Ranking List because I’ve written that real estate is my favorite investment class to build wealth. Real estate doesn’t stack up well against the other passive income sources due to the lack of liquidity and constant maintenance of tenants and property. The returns can be huge due to rising rental income AND principal over time, much like dividend investing. If you are a “proactive passive income earner” like myself, then real estate is great.”
Ethiopia’s main challenges are sustaining its positive economic growth and accelerating poverty reduction, which both require significant progress in job creation as well as improved governance. The government is devoting a high share of its budget to pro-poor programs and investments. Large scale donor support will continue to provide a vital contribution in the near-term to finance the cost of pro-poor programs.
ie first you need to haul ass and do something crazy, eg write a quality 20,000 word ebook (insanely not passive hahahah), but then you get to sit back and enjoy seeing PayPal sale messages pop up on your iPhone each morning as sale after sale after sale is made…on an ongoing basis and without any additional work. That’s some seriously Pina Colada flavored passive goodness!
1) If your property is not under rent control, you have the ability to raise rent to market prices with proper warning. In SF, I have to give tenants a one month warning for up to a 10% increase and a two month warning for up to 60%. Rent control limits to an inflation index, usually around 2% a year, which is why initial pricing and tenant turnover is important for better profitability.
If you’ve been passionately collecting something over the years, this may well be your route to extra income. Be it comic books, records, stamps or even vintage clothing you picked up from second-hand stores, the chances are likely that there is someone out there who shares your passion. Whilst sites like eBay and Amazon are ideal for generic selling, if your collection consists of more niche items, you may need to use a more specific platform.
The first time I did affiliate marketing was way back in the day on my architecture exam website. I connected with a company that sold practice exams, which gave me $22 for every person who bought one of their exams via my site. Since then, I’ve generated over $250,000 simply by recommending that product alone. Again, this is a product that was not mine, but one that has still been helpful to my audience. This was all done with thousands of visitors a month. Not millions, or even hundreds of thousands.

And, let’s face it; not everyone wants to sling body wraps or nutrition shakes to their family and friends. That’s why offering a service is often one of the best, and least uncomfortable, ways to earn side income doing something you love. Maybe you want to clean houses or rake leaves or help people file their taxes. It’s totally up to you, and that’s the beauty of this option.
