How BAH Changes When You PCS: What to Expect and How to Plan
PCS moves change your BAH rate, sometimes significantly. Here's the exact timeline of when rates change, what you receive during the move, and how to budget the gap.
BAH is one of the most variable parts of military compensation — it can change dramatically with a single PCS move. A move from Fort Campbell to Fort Meade or San Diego can swing your monthly housing allowance by hundreds of dollars in either direction.
Here's how BAH works across a PCS and how to avoid getting surprised.
When Your New BAH Rate Takes Effect
Your new duty station BAH rate begins on the effective date of your orders, not on the day you physically arrive. This is a key distinction.
If your PCS orders are effective June 1 and you drive across the country, arriving June 15, you receive your new duty station BAH rate starting June 1 — even if you spent June 1–14 in transit or staying with family.
Similarly, if your old duty station BAH rate was higher than your new one, the rate drop happens on the orders effective date, not when you check in.
What Happens to Your Old BAH
Your old duty station BAH stops on the effective date of your orders. You do not continue receiving it during your move, with one exception: if your PCS orders allow for Dependent Advance (where your family stays behind temporarily for school or other reasons), the rules become more complex.
For the standard case — family moves together on orders — old BAH stops and new BAH begins on the orders effective date.
Move-In Housing Allowance (MIHA)
If you're moving OCONUS (overseas), you may receive a Move-In Housing Allowance (MIHA) — a one-time payment to cover furnishing and initial setup costs in overseas housing. MIHA rates vary by location and are published by the Defense Travel Management Office.
MIHA is separate from OHA (Overseas Housing Allowance) and is paid once upon arrival, not monthly.
Temporary Lodging Allowance (TLA) and TLE
During a PCS move, you may be authorized temporary lodging before moving into permanent housing:
TLE (Temporary Lodging Expense) — For CONUS moves, up to 10 days of lodging expense reimbursement at government-specified rates, either at the old or new duty station. You still receive BAH during this period.

TLA (Temporary Lodging Allowance) — For OCONUS moves, a similar allowance for the period before you obtain permanent housing overseas.
Note: TLE and TLA do not replace BAH — they are separate reimbursements for temporary lodging costs during the physical move.
BAH Gap: The Deposit Problem
One of the most common financial crunches during a PCS: you need a security deposit and first month's rent for your new place before you receive your first paycheck with the new BAH rate.
If your new BAH is $2,000/month, a landlord requiring first month + last month + deposit may want $6,000 upfront. If you're arriving mid-month, you also need to cover partial rent for the remainder of the month.
Planning: Budget 2–3 months of your new BAH rate as your PCS housing reserve. This covers deposit, early rent, and the overlap period.
When BAH Goes Down: Rate Protection
If your new duty station has a lower BAH rate than your current station, your rate simply drops on the orders effective date — there is no phased reduction or cushion. This is a real budget shock for service members moving from high-cost locations (San Diego, DC) to lower-cost ones.
However: if the DoD reduces BAH rates in a location during an annual survey year (meaning local rents dropped), existing residents are rate-protected — they keep their previous rate. PCS moves reset this protection; you start at the current rate for your new location.
When BAH Goes Up: The Good News
Moving from a lower-cost installation to a higher-cost area can meaningfully increase your housing allowance. Many service members who move to San Diego, Northern Virginia, or Hawaii for the first time are surprised by how much their BAH increases.
If you're making a choice between on-post quarters and off-post housing at a high-BAH location, run the full math. In some locations, off-post housing cost equals BAH, leaving you no out-of-pocket housing expense.
