I qualify to collect my full age retirement benefit (age 66.2 years). I'm still working and don't need the SS income. The additional income will move me to the next federal tax bracket (I'm at 24% now). Is it better to collect and invest all the monies or wait until 70 for the additional 8% per year increase?

Hi. It sounds like it would likely be smart for you to wait until age 70 for a number of reasons. Here is a link to an article that Larry wrote on this topic: https://www.forbes.com/sites/kotlikoff/2018/11/25/it-might-be-worse-to-t....
