Start an affiliate marketing website: This passive income model works for individuals who already own a bog or website. Here, your business goal is to contact companies and offer to tout their products and services, usually for a fee or a commission, based on the number of page views you get. Studies show that more people spend time online and less watching TV or reading the newspaper. Take advantage of that leverage and earn income from the tens of thousands of companies who want to reach an audience - maybe your audience. Either reach out to companies directly or go through a site like ClickBank, which offers affiliate marketing opportunities.
Once your audience has grown and you have validation that you’re offering them value, there are many ways to create passive income. You could sell digital products like ebooks or courses, take up affiliate marketing in which you promote other company’s products and earn a commission when you sell that item to your audience, build a community and charge people to be a part of it, create software and sell that, among other avenues. Ask your audience directly what would serve them best, or look at what they’re saying on Twitter, Facebook or other websites, to find out what problems they have and how you could help solve them.
The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.

What about getting hit with AMT (Alternative Minimum Tax) in cases your passive income / capital gains are too high? I’m not that familiar with the details of AMT, but I got hit with AMT one time due to an “exercise and hold” of ISOs (stock options). My CPA explained it’s another method of calculating my tax liability, and in cases I gain too much capital gains, the IRS may treat and tax them as ordinary income.

Book sales ($36,000 a year): Sales of How to Engineer Your Layoff" continue to be steady. I expect book sales to rise once the economy starts to soften and people get more nervous about their jobs. It's always best to be ahead of the curve when it comes to a layoff by negotiating first. Further, if you are planning to quit your job, then there is no downside in trying to engineer your layoff so you can get WARN Act pay for several months, a severance check, deferred compensation, and healthcare.
A great source of passive income is advertising dollars from other businesses and people.  If you have a website, blog, or strong social media following, other businesses will start to take notice.  A trick I have learned in this space is that it is much less expensive and faster to go where people already are then to try and create it yourself.  But, if you create it yourself, then others will come to you.  This is how you turn you blog, etc. into passive income.  Let’s say your blog has 300,000 visitors a month, that’s quite the following!  Other businesses and people looking to advertise a product or service would rather come to you and pay you to have their advertising on your blog.  This is less expensive for them since you have already created an audience for them, and great for you since they are paying you for this audience. 
Many entrepreneurs are asking if the new rules will result in them paying additional taxes if their corporations generate passive income in excess of $50,000. In most circumstances, the answer is that they will pay more corporate taxes, thereby reducing the size of their tax deferral advantage (from 40% down to 27% on their 2019 corporate income earned in Ontario).
I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.

Where a CCPC has a RDTOH balance, since it has earned passive income, yet has also earned income that is active not subject to the small business deduction, there is an opportunity to benefit from additional deferral. The income that was taxed at the active tax rate of 26.7% would be eligible to be paid to the shareholder as an eligible dividend (“Eligible Dividend”). When an Eligible Dividend is paid that generates a tax refund from the RDTOH pool of the company, there is a 4% tax savings than if the dividend was not an Eligible Dividend. Profits from passive income do not need to be paid as a dividend that is not an Eligible Dividend to the shareholder for the corporation to recover its RDTOH pool. There is currently no ordering rule or tracking system forcing corporations to declare and pay a dividend that is not an Eligible Dividend taxed at a higher rate in the individual’s hands in order for it to recover its RDTOH.
You will get a good gauge of the market when you release your app. It’s analogous to going fishing. You have to cast your app out to see if anything bites. Once you get a few bites, you can start adding a few new features to improve your app passive income. A couple bells and whistles. Finally, start paying attention to feedback. The best way to set yourself up for success with both analytics and feedback are to integrate them both before releasing your app.
Despite some ups and downs in recent years, real estate continues to be a preferred choice for investors who want to generate long-term returns. Investing in a rental property, for example, is one way to produce a regular source of income. At the outset, an investor may be required to put up a 20% down payment to buy the property, but that may not be a barrier for someone who's already saving regularly. Once reliable tenants are installed, there's very little left to do except wait for the rent checks to begin rolling in.

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.
The appeal of these passive income sources is that you can diversify across many small investments, rather than in a handful of large ones. When you invest directly in real estate, you have to commit a lot of capital to individual projects. When you invest in these crowdfunded investments, you can spread your money across many uncorrelated real estate ventures so individual investments don't cause significant issues.

If a closely held corporation is actively engaged in equipment leasing, the equipment leasing is treated as a separate activity not covered by the at-risk rules. A closely held corporation is actively engaged in equipment leasing if 50% or more of its gross receipts for the tax year are from equipment leasing. Equipment leasing means the leasing, purchasing, servicing, and selling of equipment that’s section 1245 property.
A working interest in an oil or gas well which you hold directly or through an entity that doesn’t limit your liability (such as a general partner interest in a partnership). It doesn’t matter whether you materially participated in the activity for the tax year. However, if your liability was limited for part of the year (for example, you converted your general partner interest to a limited partner interest during the year) and you had a net loss from the well for the year, some of your income and deductions from the working interest may be treated as passive activity gross income and passive activity deductions. See Temporary Regulations section 1.469-1T(e)(4)(ii).
Active income means you are doing something in order to receive that income. Some kind of work. Some kind of effort. You are not hands-off. You have to exert some kind of energy and time towards earning that income. Passive income means you are earning regular income with little to no effort required to keep it coming. You are for the most part hands-off.
I just started out with Affiliate Marketing (idea # 8) and it is not as easy as people make out to be. For me, the hardest part so far, is learning Search Engine Optimization (SEO) and driving traffic to my website. I’m only 3 months into it, but I am confident that the site will begin to generate some incom., I have to give it 6-9 months, so we’ll see.
