Letterkenny Army Depot draws its rates from the Carlisle Barracks military housing area. In 2026 an E-5 with dependents receives $2,076 a month and an E-5 without dependents $1,617. An E-7 with dependents receives $2,442. 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 covers a three-bedroom at the local benchmark with $251 a month left over. The benchmark is HUD's FY2026 fair market rent of $1,825 — 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.
Chambersburg Area School District serves families living off post at Letterkenny Army Depot. 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.
Letterkenny Army Depot falls in the TRICARE East region — the contractor there is Humana Military. 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.
Pennsylvania fully exempts active-duty military pay and allowances from state income tax. 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 Letterkenny Army Depot 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.
