If myhusband and I are both active duty, stationed in the same state but have different states of residence/home of record, how do we file state returns?

That can get messy, and it might be best to use a professional to file taxes for 2024.  And NOT a seasonal storefront.....but someone who works year-round, locally near your post, on military taxes regularly and who would be experienced in such situations.

Here's what I mean....it really depends on what states are involved, and there may not be helpers in this forum, who can figure out the details for each of the states involved.

Yes, you likely need to file for both states....if both states assess an income tax.

1)  Some states have a way for you to file MFJ-Federal and MFJ-state, with a way in the software to take out the non-resident spouse's income. (NC allows this, but I have no idea what other states allow it).

2) Other states would require you both to file MFS-Federal and MFS-State such that each of you can report only your own income, and not your spouses.

3)  Then some community property states might require some community property/income reporting on one or both tax returns.

4) Finally, if your husband changed his state of legal residency (SLR) state during 2024  (filed a DD2058), then he might also be required to file a part-year tax return for both his former, and new SLR state, for 2024, IF both states have an income tax.  (see also:

i.e., could be a giant mess....depending on the states involved.
