Yeah. This started during the pandemic. And there were some messages from people on internal message boards along the lines of... but... such and such a state has a requirement that taxes be filed for even a day (which, frankly, would have been cheaper for me to pay out of pocket than to pay for my accountant to file an additional state filing). But said employer apparently decided to ignore de minimus travel stuff though I know people who actually spent a lot of time out of state did need to keep track.

But, also yeah, MA and NH had a bit of a spat over workers at an MA company who lived in NH who just stopped coming in and therefore stopped filing MA taxes.
