I have had the exact same situation come up with my work. I have worked from home since 3/20 and haven't had any MA taxes taken out at all since about 1/21. HR had to record something about me either being remote full-time or working in the office. Since my commute is 2 hours each way, I have been fighting tooth and nail to keep working from home. Starting a new job in a couple months that is more pay and permanent remote though so 🤞
