Moving on orders doesn't have to change the state you pay income tax to.
Key facts
The SCRA lets active-duty members keep their legal residence in the place they consider home.
The Military Spouses Residency Relief Act lets spouses keep a residence too.
Since the Veterans Auto and Education Improvement Act of 2022, spouses can choose the service member's residence, their own, or the duty station state, for tax purposes.
How to apply
How to get it: Talk to your installation legal office or a MilTax consultant before you change anything, and keep proof of your residence (voting, license, vehicle registration).
Tax laws change every year and you may still need to file to claim the exemption. Confirm with your state's tax agency (via USA.gov) or a free MilTax consultant.
