Because of Covid the majority of my office has been working remotely since March. They are actually limiting the number of people that can come to the office to 25% of capacity, and you have to get permission to be on the list.

I am considering visiting my parents to help out for a few weeks (my dad has had some recent health problems). I would work remotely from their house. They reside in a different state, and I am curious when this becomes an issue with taxes and regulations. I have gone to visit work locations in different states for a few different companies. Our CEO visits many out of state locations, so I know it is just not physically being in another state that causes a change. So what triggers having to worry about this?
