NEW Travel Policy!

Effective for routine IRIS staff and committee travel beginning on or after July 1, 2019, IRIS will reimburse travel meals and incidental expenses (M&IE) on a per diem basis, using the applicable U.S. government rates.  IRIS program travel (e.g., interns, experiment support) may have other guidelines, so please consult IRIS Financial Services (admin@iris.edu) or your program travel coordinator for transition details.

  1. The domestic CONUS per diem rates can be found on the GSA website.
  2. The Department of Defense sets rates for Alaska, Hawaii, U.S. Territories, and Possessions (OCONUS rates).
  3. The State Department sets foreign rates.

The per diem rate is determined by the destination city as listed on the travel authorization form.

  • The first and last day of travel is calculated at 75%.
  • Deduct any meals provided/paid by others using the M&IE breakdown tables.
