Mountain Home Air Force Base is an Air Force installation in Mountain Home, Idaho.
Housing here is priced in the Mountain Home AFB military housing area. 2026 BAH for an E-5 with dependents is $1,605 a month, against HUD's FY2027 fair market rent of $1,779 for a three-bedroom — about $174 a month short of the rent.

ID exempts pay earned while stationed outside Idaho. Care here falls under the TRICARE West region. Families living off post are served by Mountain Home School District #193.
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).

Mountain Home Air Force Base draws its rates from the Mountain Home AFB military housing area. In 2026 an E-5 with dependents receives $1,605 a month and an E-5 without dependents $1,524. An E-7 with dependents receives $2,238. The rate depends on the housing area, your paygrade and whether you have dependents — not on your ZIP code, and not on whether you rent or buy.
For an E-5 with dependents, it falls roughly $174 a month short of a three-bedroom at the local benchmark. The benchmark is HUD's FY2027 fair market rent of $1,779 — a 40th-percentile gross rent, so it includes tenant-paid utilities and half the local market rents for more. Anything above that benchmark comes out of pocket, and anything below it you keep: BAH pays the same rate whatever your actual rent turns out to be.
No. BAH is a non-taxable allowance, so it does not appear as taxable wages on your W-2 and no federal or state income tax is withheld from it. That makes a dollar of BAH worth noticeably more than a dollar of base pay, which is why comparing a civilian salary against base pay alone understates military compensation.
Mountain Home School District #193 serves families living off post at Mountain Home Air Force Base. Enrollment normally needs the previous school's records, immunizations and proof of address, and the installation's School Liaison Officer can start that before you arrive.
Mountain Home Air Force Base falls in the TRICARE West region — the contractor there is TriWest Healthcare Alliance. Your region decides who pays your claims and where referrals are authorized, so a PCS that crosses regions means transferring your enrollment — Prime enrollment does not follow you automatically, and letting it lapse drops you to TRICARE Select with its cost shares.
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. Being stationed in a state does not by itself make you a resident of it: state income tax follows your state of legal residence, and the Servicemembers Civil Relief Act protects that against an involuntary PCS.
Most of it is reimbursed rather than paid. A PCS to Mountain Home Air Force Base normally pays a dislocation allowance, a mileage allowance for driving your own vehicle, per diem for you and each dependent while you travel, and temporary lodging once you arrive. Choosing a personally procured move pays you the government's cost for the same shipment, so the profit — and the tax on it — depends on your weight and the distance. The PCS calculator estimates all of those for this destination.
