I thought DC and VA have a recipricol agreement where they do not tax each others residents. And DC does not have a non resident return, so if one moved from DC to VA, I do not know how DC would tax a bonus earned while a DC resident and paid while a VA resident. I do not think they have an accrual rule for moving out of the state, although I am not sure.
I would be interested in knowing about this more if anyone knows.
Thank you,
