No, do not change it. You are still considered a "Resident" of CT for the entire year, no matter where stationed ...at least for 2024
CT does have some complex situations where you will be considered to be taxed as a non-resident of CT (for state tax purposes)...but that doesn't mean you are a resident of the state you are posted to...that is just for CT tax purposes. Read the examples lower down on the page on the following CT web page:
IP 92(2.5) Connecticut Income Tax Information for Military Personnel and Veterans
___________________________________
Note: that even though you may be posted out of CT for entire year...sometime in the future, you do not become a domiciled resident of any other state that you are posted to, unless you take legal steps to become a domiciled resident of that state that you are posted to. In order to do that, you would need to file a DD form 2058 with your Military HR/Personnel and finance offices to change your "State of legal Residence" (SLR). Such a DD2058 submission must usually show you have taken steps to change your Banking, Drivers Lisc, Car registrations, registered to vote etc...etc.. to the new state.
BUT, as a military member, you are not required to do so, even if posted in another state for a few years. Most military service people do not do that if they are only in service for a few years (tthus limiting the mess of part-year tax returns), and are then only subject to the state tax rules for their HOR state....but some occasionally do change their SLR if they decide to make a career in the service.
