This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.
