My employer has been around for a long time and is financially extremely conservative so I am willing to take the risk.
Unfortunately, apparently you need to submit your W2 when applying for financial aid so it will look very strange to the financial aid officer at the college if your medicare income is 100's thousands dollars more than your taxable income. As a result, I will not be applying for financial aid for my kids when they go to college. It will be kind of embarrasing if they ask me about this, because clearly I am highly compensated.
That said, I would be very interested in learning more if someone with real-life experience tells me it actually works. My family is actually living a pretty frugal life because I am putting most of my base salary and cash bonus into my NQDC account.
