Yeah...but...a DD2058 is only "normally" used if you are posted to a non-taxing state, like TX or WA, or FL..
IF your new post is in PA, and you DD2058 as your new State of Legal Residence (SLR) then you have to pay PA taxes as long as you are posted in PA...and in the year of the change, would have to file messy NY and PA part-year tax returns.
If NY is your actual HOR right now, you leave the DD2058 alone as it is never something you "have" to file unless you do decide the change your SLR state to the one you are posted to. (just keep it in mind if you ever get posted to TX or other non-income-taxing state)
Now, as I recall, if NY is your HOR, NY only taxes that military income if you are actually posted or living in NY more than 20 days during the year...so if you are posted out of NY for almost all of the year, then the military income isn't taxed...group A:
