It's very possible neither you nor your husband have to file a North Carolina return, due to MSRRA.
What is your active duty husband's HOR (Home of Record) with the military? Active duty servicemembers whose only income is military pay file taxes in their Home of Record, not in the state where they happen to be stationed due to military orders. The spouse of an active duty servicemember may choose to file in her servicemember's home of record (even if she's never lived there), or in her own home state (it's the spouse's choice). She is not required to file in the state where she happens to be stationed with her husband.
