I learned about both of these through lecture today. I got some rsu-s through my emploter however it looks like 83(b) time window passed as election for 83(b) requires to do within a month of grant date. Now 83(i) option for delaying tax up to 5 years available as an option but my company is a publicly traded company whose stock listed in nasdaq. This makes it non-qualified for 83(i), no? yes? Thanks.,
