§433 Allowance for Muster Duty

Title 37 › CHAPTER 7 — ALLOWANCES OTHER THAN TRAVEL AND TRANSPORTATION ALLOWANCES › § 433

Last updated Aug 21, 2026|Official source

Summary

Members of the Ready Reserve who are not in the National Guard or Selected Reserve get a pay allowance when they do muster duty under section 12319 of title 10, if they are on that duty for at least two hours. The amount is 125 percent of the average per diem rate for the continental United States (excluding Alaska and Hawaii) found in section 452, using the rate that was in effect on September 30 of the year before the duty. The payment must be cash, not goods. Rules made by the Secretaries in charge explain how it is paid. It can be paid before, on, or after the duty, but no later than 30 days after. This single flat payment covers travel, transportation, meals, and any special costs from being away from home (including weekends and holidays), and it is full payment no matter the member’s rank. If a member gets this muster allowance, they cannot also be paid inactive‑duty training pay under section 206(a) for the same time.
