I understand your point but axing the entire tax portion of this problem is massive. Sure, your employer would probably still have to know to some degree, but it would be much easier and could end up with something like "you don't need to tell us unless you're working from $listOfPlaces".

Good luck getting that (potentially every changing) list from the hands of your HR and legal departments! Remember, that (at least in US) lot of protections and laws change quite frequently and not knowing where an employee is would put the company at huge risk. Companies, for most part, establish their bases where they find local laws are favorable to them (in addition to ability to find enough able warm bodies to fill the positions), they don't want to open themselves up to lawsuits, legal hassle, what-nots from state/city the laws of which they are not fully appraised of all the time! What happens when that @listOfPlaces change, say every year?
