State tax and TRICARE in Idaho
Idaho. Idaho taxes an Idaho resident's active-duty pay unless it is earned while stationed outside Idaho for at least 120 consecutive days. Pay earned in Idaho is taxable.
SCRA. Under the Servicemembers Civil Relief Act your military pay is taxed by the state you are domiciled in, not by the one your duty station sits in. Being assigned to Mountain Home Air Force Base does not by itself change which state may tax you, and it does not create a filing obligation where you are stationed.
TRICARE West. Care at Mountain Home Air Force Base falls under the TRICARE West region, administered by TriWest Healthcare Alliance — enrollment and claims run through 888-TRIWEST (874-9378).
