For instance, a business owner who works in the company she or he founded would have to pay an extra 15.3 percent in self-employment payroll taxes compared to someone who merely had a passive interest in the same limited liability company who would pay only income taxes. In other words, the same income earned actively would be taxed at a higher rate than if it were earned passively.

Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
