It doesn’t pay much, but if you’re a healthy person and want to make a bit of extra money online, the AchieveMint app will reward you for doing things like walking, tracking your food, or taking health surveys. AchieveMint works by connecting to fitness apps you might already be using like Fitbit, RunKeeper, Healthkit, and MyFitnessPal and then giving you points for certain actions. For every 10,000 points, you earn $10 with no limit on your earnings.

When money is lent to a partnership or S-corporation acting as a pass-through entity (essentially a business that is designed to reduce the effects of double taxation) by that entity’s owner, the interest income on that loan to the portfolio income can qualify as passive income.

Many affiliate programs run with last-click attribution, where the affiliate receiving the last click before the sale gets 100% credit for the conversion. This is changing. With affiliate platforms providing new attribution models and reporting features, you are able to see a full-funnel, cross-channel view of how individual marketing tactics are working together. For example, you might see that a paid social campaign generated the first click, Affiliate X got click 2, and Affiliate Y got the last click. With this full picture, you can structure your affiliate commissions so that Affiliate X gets a percentage of the credit for the sale, even though they didn’t get the last click.

The IRS states, however, that if the investor did help manage the company with the owners, the investor's income could be seen as active since the investor provided "material participation."
