My friend let’s talk in the present.
Cheaper location move can also mean less pay https://www.marketwatch.com/story/facebook-employees-may-fac...
I think you can still come out ahead if you have a ton of stock to vest, because they can’t cut that, but you still benefit from the lack of state tax there. But once the plague situation ends I think WFH employees will be in a weaker position and tend to get smaller refresh grants. It could be a great one-year-only move for anyone who’s due for a windfall from one of these IPOs.
But if remote work becomes the norm, companies will update the location. My comment had nothing to do with updated incomes based on the location which is of course going to be the reality.
Disclosure: not a tax accountant, talk to to one if you want accurate information.
