If you can save a lot early on in life, you can build up sources of unearned income, and this income will be exempt from payroll taxes. This is good news for investors and for retirees. Any pre-tax salary deferral contribution made to a retirement account, pension plan, or other pre-tax contribution will lower the amount of federal and state income tax liabilities, however, they do not lower your payroll/FICA tax - the FICA tax has already been taken out of gross wages. 

Great breakout of some common items that are (mostly) accessible to individuals. My biggest issue with p2p is the ordinary interest it generates and the ordinary tax that we have to pay. That really takes a bite out of the returns. Fortunately, I opened an IRA with one of the providers to juice the return with zero additional risk. 6-8% nominal returns over a long period of time will make me very happy. It should end up as 5-7% of the portfolio anyway, so nothing too significant.
I prefer assets that make me a high return for the lowest amount of work possible (semi-passive involvement). And assets that pay me in several unique ways. Cash flow is only one way RE makes money for me. I also get principal reductions, appreciation, tax advantages (depreciation), and I control the rental increases on a yearly basis. Plus a majority of the capital is provided by the secondary market on 30 year fixed low interest rate debt.

The ideas that follow are not truly “passive income,” in that they require a significant amount of effort. However, I’m defining the term loosely and considering anything where one hour of work does not equal one hour of pay as passive income. The idea is that you put the work in up-front and then reap the benefits down the road. Read on for my top 10 passive income ideas!
Passive income bluntly is income that would continue to generate if you died. Morbid. How about this? Passive income is income that would continue to generate if you decided to do nothing and sunbathe on some beach. That sounds better. Passive income includes rental income, royalties and income from businesses or investment partnerships / multi-member LLCs where you do not materially participate.

“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.”
Special rules regarding passive activity losses were enacted in 1986 to limit the amount you could reduce your tax liability from passive income. However, you can still reduce your non-passive income up to $25,000 if your income is below $150,000 and you actively participate in passive rental real estate activities. This amount is phased out between $100,000 and $150,000. Other than this exception, you may only claim losses up the amount of income from the activity. Losses that can not be claimed are carried forward until the property is disposed of or there is adequate income to offset the loss. Real property and other types of investments, if they qualify, may also be used in a 1031 exchange to avoid paying taxes on the income from the sell of the property. This only applies if the proceeds from the sell are used to purchase a similar investment.
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
