That wouldn't have applied in any case, since that temporary rule applied to former in-state workers who temporarily relocated out of state due to the pandemic. The taxpayer here was never an in-state worker to begin with.

In general, you owe income tax to the state where you physically live, and where you physically perform the work. There are 6-7 states that tax telework, but Massachusetts is not one of them. However, you will owe a non-resident Massachusetts tax return to report and pay tax on any wages earned while you are physically in the state of Massachusetts, even temporarily. For example, if you are required to attend in-person meetings or training 1 day per month, then about 5% of your wages would be considered MA state wages and you would report them and pay taxes on a non-resident return. Be sure to track the days you perform work in Massachusetts, if any.
