Single member S Corp Profits for Reinvesting

I am a single-member LLC that elected to become an S Corp for the 2021 tax year. Are s-corp employees required to receive a paycheck? 


I'm aware of the discussion on the salary vs dividend ratio but I would like to continue having business income pay for my certifications, equipment, and training instead of having to take a portion early on. I a salary MUST be distributed, can I withdraw my request for S Corp election that same year I requested it?
